WEBVTT 00:00:00.000 --> 00:00:01.944 align:middle line:90% [SQUEAKING] 00:00:01.944 --> 00:00:03.888 align:middle line:90% [RUSTLING] 00:00:03.888 --> 00:00:10.692 align:middle line:90% [CLICKING] 00:00:10.692 --> 00:00:11.680 align:middle line:90% [APPLAUSE] 00:00:11.680 --> 00:00:13.760 align:middle line:84% PROFESSOR: And our next speaker is 00:00:13.760 --> 00:00:16.820 align:middle line:84% Brock Yordy from the Geothermal Drilling Association, 00:00:16.820 --> 00:00:19.880 align:middle line:84% and he had the pleasure of collaborating with Brock 00:00:19.880 --> 00:00:23.020 align:middle line:84% this past summer to do geothermal driller 00:00:23.020 --> 00:00:24.660 align:middle line:90% pre-apprentice program. 00:00:24.660 --> 00:00:26.160 align:middle line:84% PROFESSOR: Did she not take him out? 00:00:26.160 --> 00:00:27.618 align:middle line:84% BROCK YORDY: So how does this work? 00:00:27.618 --> 00:00:30.175 align:middle line:90% Do I still have 20 minutes or? 00:00:30.175 --> 00:00:31.300 align:middle line:90% PROFESSOR: So sorry, Brock. 00:00:31.300 --> 00:00:33.903 align:middle line:90% 00:00:33.903 --> 00:00:35.820 align:middle line:84% They wanted you to put it on the next guy, so. 00:00:35.820 --> 00:00:37.040 align:middle line:90% BROCK YORDY: Oh, excellent. 00:00:37.040 --> 00:00:38.880 align:middle line:84% So we're going to do introduction 00:00:38.880 --> 00:00:43.080 align:middle line:84% to geothermal drilling, abridged in 20 minutes. 00:00:43.080 --> 00:00:44.660 align:middle line:84% There's plenty of things in here. 00:00:44.660 --> 00:00:48.020 align:middle line:84% And we have heard about how drilling affects us. 00:00:48.020 --> 00:00:52.040 align:middle line:84% And I think any of you that are flipping the television 00:00:52.040 --> 00:00:55.200 align:middle line:84% and you come across FX and you see the movie Armageddon, 00:00:55.200 --> 00:00:57.360 align:middle line:84% you can see that the major premise 00:00:57.360 --> 00:01:00.820 align:middle line:84% is it's easier to teach drillers to be astronauts 00:01:00.820 --> 00:01:03.480 align:middle line:84% than it is to teach an astronaut to be a driller. 00:01:03.480 --> 00:01:07.180 align:middle line:84% When Ben Affleck asked that question, 00:01:07.180 --> 00:01:09.560 align:middle line:84% some choice words were used by Michael Bay, 00:01:09.560 --> 00:01:12.740 align:middle line:84% but in reality, suspension of disbelief 00:01:12.740 --> 00:01:14.440 align:middle line:90% is what we're looking at. 00:01:14.440 --> 00:01:20.180 align:middle line:90% 00:01:20.180 --> 00:01:21.160 align:middle line:90% Jump past that. 00:01:21.160 --> 00:01:22.920 align:middle line:90% OK, here's my warning. 00:01:22.920 --> 00:01:25.380 align:middle line:84% The following presentation features tribal drilling 00:01:25.380 --> 00:01:27.620 align:middle line:84% knowledge acquired by drilling professionals 00:01:27.620 --> 00:01:30.520 align:middle line:84% or under the supervision of geothermal professionals. 00:01:30.520 --> 00:01:33.220 align:middle line:84% Accordingly, me, must insist that everyone 00:01:33.220 --> 00:01:35.580 align:middle line:84% who engages with drilling in this presentation 00:01:35.580 --> 00:01:38.540 align:middle line:90% consider this advice. 00:01:38.540 --> 00:01:42.040 align:middle line:84% Drilling is the imperfect combination of science, 00:01:42.040 --> 00:01:45.660 align:middle line:84% physics, and self-taught tribal knowledge compounded over years 00:01:45.660 --> 00:01:47.860 align:middle line:90% of success and failure. 00:01:47.860 --> 00:01:50.780 align:middle line:84% Drilling is a disruptive process. 00:01:50.780 --> 00:01:52.420 align:middle line:90% We know this. 00:01:52.420 --> 00:01:55.500 align:middle line:84% The key to the success lies in your conscious choice 00:01:55.500 --> 00:01:58.080 align:middle line:84% of the drilling program that minimizes the impact 00:01:58.080 --> 00:01:59.900 align:middle line:90% of the surrounding environment. 00:01:59.900 --> 00:02:01.140 align:middle line:90% That's the borehole. 00:02:01.140 --> 00:02:02.300 align:middle line:90% That's the neighbors. 00:02:02.300 --> 00:02:05.320 align:middle line:84% That's the project staying on time. 00:02:05.320 --> 00:02:08.080 align:middle line:84% Drillers, contractors, engineers, scientists 00:02:08.080 --> 00:02:11.240 align:middle line:84% and clients have entered into a powerful partnership 00:02:11.240 --> 00:02:14.120 align:middle line:84% to uncover the mysteries of the subsurface. 00:02:14.120 --> 00:02:18.640 align:middle line:84% We are discovering the unknown together. 00:02:18.640 --> 00:02:21.080 align:middle line:90% And how are we going to do that? 00:02:21.080 --> 00:02:24.480 align:middle line:84% Abridged version, 20 minutes, right? 00:02:24.480 --> 00:02:25.300 align:middle line:90% It's simple. 00:02:25.300 --> 00:02:26.800 align:middle line:84% We have a drilling system, and we've 00:02:26.800 --> 00:02:30.780 align:middle line:84% seen this from the OG Karen Eubanks, who, 00:02:30.780 --> 00:02:35.580 align:middle line:84% as we've talked a lot, geology, formation, hydraulics, 00:02:35.580 --> 00:02:38.340 align:middle line:84% depth to water, subsurface challenges. 00:02:38.340 --> 00:02:40.720 align:middle line:84% Those are the things that I'm thinking about when we say, 00:02:40.720 --> 00:02:42.320 align:middle line:90% Can we drill this? 00:02:42.320 --> 00:02:46.180 align:middle line:84% Next, that's going to align into my drilling capabilities. 00:02:46.180 --> 00:02:47.940 align:middle line:90% This is my drilling system. 00:02:47.940 --> 00:02:51.160 align:middle line:84% So what can my rig capable of doing, from horsepower 00:02:51.160 --> 00:02:56.060 align:middle line:84% to rotation to pull down to pullback to diameter, depth, 00:02:56.060 --> 00:02:56.800 align:middle line:90% angle? 00:02:56.800 --> 00:02:59.820 align:middle line:84% This is all going to drive our cost. 00:02:59.820 --> 00:03:04.360 align:middle line:84% Next, choice of drilling method, back to that drilling program. 00:03:04.360 --> 00:03:06.480 align:middle line:84% Is it going to be using mud pumps, 00:03:06.480 --> 00:03:10.240 align:middle line:84% air compressors, sonic, dual rotary, reverse circulation? 00:03:10.240 --> 00:03:11.820 align:middle line:90% There are plenty. 00:03:11.820 --> 00:03:13.940 align:middle line:84% Hopefully, one day we get a rock melter. 00:03:13.940 --> 00:03:15.060 align:middle line:90% Maybe a laser. 00:03:15.060 --> 00:03:17.460 align:middle line:84% We keep seeing things come out all the time. 00:03:17.460 --> 00:03:21.500 align:middle line:84% Finally, as much as we want to say autonomy is coming, 00:03:21.500 --> 00:03:24.340 align:middle line:84% and it's really cool watching the Dragon rocket go up 00:03:24.340 --> 00:03:29.740 align:middle line:84% and there's nobody really at the control, but they still-- 00:03:29.740 --> 00:03:32.280 align:middle line:84% individual can be at that stick at any moment. 00:03:32.280 --> 00:03:35.180 align:middle line:84% And this processing right here will always 00:03:35.180 --> 00:03:37.600 align:middle line:84% be very important to what we're doing. 00:03:37.600 --> 00:03:39.840 align:middle line:84% So our driller, our drilling company, 00:03:39.840 --> 00:03:42.060 align:middle line:84% our contractors' qualifications, What 00:03:42.060 --> 00:03:43.680 align:middle line:90% special tools do they bring? 00:03:43.680 --> 00:03:44.600 align:middle line:90% What methods? 00:03:44.600 --> 00:03:47.980 align:middle line:84% What applied science and fundamentals? 00:03:47.980 --> 00:03:51.320 align:middle line:84% So as I think of that, the driller, 00:03:51.320 --> 00:03:53.850 align:middle line:84% we talk about workforce development. 00:03:53.850 --> 00:03:55.450 align:middle line:90% We talk about developing this. 00:03:55.450 --> 00:03:58.130 align:middle line:84% The Liftoff report talks about where we need to be, 00:03:58.130 --> 00:03:59.530 align:middle line:90% what we need for workforce. 00:03:59.530 --> 00:04:04.670 align:middle line:84% He and I, with Stacy right here in the front row with the time, 00:04:04.670 --> 00:04:09.110 align:middle line:84% and we have collaborated a ton on workforce development 00:04:09.110 --> 00:04:10.890 align:middle line:90% and developing these drillers. 00:04:10.890 --> 00:04:13.910 align:middle line:84% But the critical system that I just showed you 00:04:13.910 --> 00:04:17.070 align:middle line:84% doesn't work without a competent drill crew. 00:04:17.070 --> 00:04:20.370 align:middle line:84% That's working in safety first, because we're rotating, 00:04:20.370 --> 00:04:24.510 align:middle line:84% we're percussing, we're lifting things over our heads. 00:04:24.510 --> 00:04:27.970 align:middle line:84% So as that drill crew steps up into this critical system, 00:04:27.970 --> 00:04:30.070 align:middle line:90% what's their goal for the day? 00:04:30.070 --> 00:04:33.310 align:middle line:84% What is the quality of the installation? 00:04:33.310 --> 00:04:36.550 align:middle line:84% What is the site and environmental impacts 00:04:36.550 --> 00:04:37.570 align:middle line:90% and management? 00:04:37.570 --> 00:04:39.530 align:middle line:84% What is the goal for project completion? 00:04:39.530 --> 00:04:41.890 align:middle line:84% Staying on time, staying under budget. 00:04:41.890 --> 00:04:43.810 align:middle line:84% Did I say under budget and I'm a drill guy? 00:04:43.810 --> 00:04:45.190 align:middle line:90% Whoa. 00:04:45.190 --> 00:04:49.070 align:middle line:84% Preparation and planning for unseen issues. 00:04:49.070 --> 00:04:55.650 align:middle line:84% For foreseeing issues, weather, those challenging geologies. 00:04:55.650 --> 00:04:58.190 align:middle line:84% Roles and responsibilities of that crew, 00:04:58.190 --> 00:05:00.930 align:middle line:90% the driller, rig operation. 00:05:00.930 --> 00:05:05.330 align:middle line:84% This is a complex process that has microsecond adjustments 00:05:05.330 --> 00:05:07.850 align:middle line:90% that need to be made at times. 00:05:07.850 --> 00:05:10.730 align:middle line:84% They need to understand this so they can have effective product 00:05:10.730 --> 00:05:14.890 align:middle line:84% installation and we get effective resource extraction 00:05:14.890 --> 00:05:17.330 align:middle line:84% so we have good project completion and good record 00:05:17.330 --> 00:05:18.050 align:middle line:90% keeping. 00:05:18.050 --> 00:05:19.770 align:middle line:90% We have an assistant driller. 00:05:19.770 --> 00:05:23.670 align:middle line:84% They're supporting that driller, rig support, tool handling, 00:05:23.670 --> 00:05:26.450 align:middle line:84% product assembly, getting into the standards 00:05:26.450 --> 00:05:29.810 align:middle line:84% that we just talked about from pressure testing to making sure 00:05:29.810 --> 00:05:33.050 align:middle line:84% our grout, making sure we're making that right hole. 00:05:33.050 --> 00:05:35.610 align:middle line:84% And then finally, our field technician, 00:05:35.610 --> 00:05:39.170 align:middle line:84% who is doing the solids control management, because, let's face 00:05:39.170 --> 00:05:42.050 align:middle line:84% it, we love this concept of drilling and putting boreholes 00:05:42.050 --> 00:05:42.730 align:middle line:90% in. 00:05:42.730 --> 00:05:46.770 align:middle line:84% We forget about the cubic yards of material we pull out 00:05:46.770 --> 00:05:51.830 align:middle line:84% of the ground and how we're going to do that 5 times to 90 00:05:51.830 --> 00:05:55.110 align:middle line:90% times to 600 to 1,000 times. 00:05:55.110 --> 00:05:57.330 align:middle line:84% And we have to be able to manage that. 00:05:57.330 --> 00:05:59.970 align:middle line:84% So three people, we can get away with two. 00:05:59.970 --> 00:06:05.190 align:middle line:84% It depends on the project, the timeline and the expectations. 00:06:05.190 --> 00:06:07.380 align:middle line:84% We're all going to become drillers today. 00:06:07.380 --> 00:06:09.990 align:middle line:90% This is the basic fundamentals. 00:06:09.990 --> 00:06:14.310 align:middle line:84% I am exerting force against our geology, 00:06:14.310 --> 00:06:16.190 align:middle line:90% and then I have to cut it. 00:06:16.190 --> 00:06:17.690 align:middle line:90% So is that in rotation? 00:06:17.690 --> 00:06:18.890 align:middle line:90% Is that in percussion? 00:06:18.890 --> 00:06:20.250 align:middle line:90% Is that in velocity? 00:06:20.250 --> 00:06:23.390 align:middle line:84% Is that in frequency, as we see with sonic drilling? 00:06:23.390 --> 00:06:27.880 align:middle line:84% Next, I have to remove those solids or it's not a borehole. 00:06:27.880 --> 00:06:30.530 align:middle line:84% It's just a thing that we got stuck in, 00:06:30.530 --> 00:06:32.910 align:middle line:84% and, man, we don't drill more boreholes. 00:06:32.910 --> 00:06:34.810 align:middle line:90% So I have to flush it. 00:06:34.810 --> 00:06:37.790 align:middle line:84% I can do this either mechanically, that's 00:06:37.790 --> 00:06:40.110 align:middle line:84% with augers, that's with frequency, 00:06:40.110 --> 00:06:43.510 align:middle line:84% or flushing with water, air, drilling fluids, engineered 00:06:43.510 --> 00:06:45.396 align:middle line:90% solutions. 00:06:45.396 --> 00:06:49.210 align:middle line:90% This is straight air rotary. 00:06:49.210 --> 00:06:52.510 align:middle line:84% We can see one's going into some rock here, 00:06:52.510 --> 00:06:55.930 align:middle line:84% and we have one going into a blue green shale. 00:06:55.930 --> 00:06:58.650 align:middle line:90% Nice, clean, out of the way. 00:06:58.650 --> 00:07:00.290 align:middle line:90% No water table here. 00:07:00.290 --> 00:07:03.850 align:middle line:84% How many times are we intersecting water tables 00:07:03.850 --> 00:07:05.170 align:middle line:90% and producing water? 00:07:05.170 --> 00:07:07.910 align:middle line:84% This is a big piece for us in our cost, 00:07:07.910 --> 00:07:09.670 align:middle line:84% in our responsibility as a driller. 00:07:09.670 --> 00:07:11.330 align:middle line:90% Here's mud rotary. 00:07:11.330 --> 00:07:12.810 align:middle line:90% Conventional. 00:07:12.810 --> 00:07:13.990 align:middle line:90% Man, it looks messy. 00:07:13.990 --> 00:07:17.250 align:middle line:84% So we immediately go, we want to go back to that other slide. 00:07:17.250 --> 00:07:17.990 align:middle line:90% But we can't. 00:07:17.990 --> 00:07:21.570 align:middle line:84% We have to select the right method for the right geology. 00:07:21.570 --> 00:07:24.970 align:middle line:84% So we get into engineered drilling solutions. 00:07:24.970 --> 00:07:29.490 align:middle line:84% Jordan, I drilled with the US military to 2,400 feet with 00:07:29.490 --> 00:07:30.350 align:middle line:90% bubbles. 00:07:30.350 --> 00:07:33.810 align:middle line:84% Got the nickname Captain Bubbles for that entire project. 00:07:33.810 --> 00:07:37.730 align:middle line:84% We can use foam with low hydraulic conductivity 00:07:37.730 --> 00:07:39.390 align:middle line:90% and carry those cuttings out. 00:07:39.390 --> 00:07:40.910 align:middle line:90% Mud, mud rotary. 00:07:40.910 --> 00:07:44.330 align:middle line:84% Why it's been predominant throughout geothermal 00:07:44.330 --> 00:07:47.490 align:middle line:84% is because, again, it's low influence to our ground. 00:07:47.490 --> 00:07:49.570 align:middle line:84% But it creates two waste streams. 00:07:49.570 --> 00:07:52.070 align:middle line:84% And we've decided those waste streams are much harder 00:07:52.070 --> 00:07:55.110 align:middle line:90% to get rid of. 00:07:55.110 --> 00:07:56.890 align:middle line:90% So let's look at this. 00:07:56.890 --> 00:07:59.170 align:middle line:84% We're going to talk conventional rotary. 00:07:59.170 --> 00:08:02.590 align:middle line:84% We could get into dual rotary, and I'll say, competent drilling 00:08:02.590 --> 00:08:04.850 align:middle line:90% companies, they're good. 00:08:04.850 --> 00:08:07.230 align:middle line:84% And they have invested in lots of different pieces 00:08:07.230 --> 00:08:08.250 align:middle line:90% of equipment. 00:08:08.250 --> 00:08:09.750 align:middle line:90% And here's the deal. 00:08:09.750 --> 00:08:12.670 align:middle line:84% They're going to sell you on their system. 00:08:12.670 --> 00:08:15.550 align:middle line:84% And sometimes those systems are bougie boreholes 00:08:15.550 --> 00:08:17.850 align:middle line:90% that go 850 feet at an angle. 00:08:17.850 --> 00:08:20.610 align:middle line:84% And we need that because of the footprint and the solution. 00:08:20.610 --> 00:08:23.510 align:middle line:84% And there's other times where we can simplify this. 00:08:23.510 --> 00:08:25.210 align:middle line:84% And if you look at the Liftoff report 00:08:25.210 --> 00:08:29.790 align:middle line:84% with 80 million buildings, we need that holistic approach 00:08:29.790 --> 00:08:31.650 align:middle line:90% of everybody drilling. 00:08:31.650 --> 00:08:33.409 align:middle line:90% This is Armageddon. 00:08:33.409 --> 00:08:36.250 align:middle line:84% We saw 3 degrees Celsius by 2100. 00:08:36.250 --> 00:08:37.770 align:middle line:90% That meteor is coming here. 00:08:37.770 --> 00:08:40.909 align:middle line:84% We all get to be Ben Affleck and Bruce Willis in this situation. 00:08:40.909 --> 00:08:44.130 align:middle line:84% So as we look at this, we have mud drilling. 00:08:44.130 --> 00:08:46.330 align:middle line:84% I need to be able to remove solids 00:08:46.330 --> 00:08:49.090 align:middle line:84% from the bottom of the borehole at the bit phase, 00:08:49.090 --> 00:08:52.810 align:middle line:84% at somewhere between 60 and 150 feet per minute. 00:08:52.810 --> 00:08:54.870 align:middle line:90% Low conductivity. 00:08:54.870 --> 00:08:58.970 align:middle line:84% I'm not going to force on those fragile formations. 00:08:58.970 --> 00:09:00.110 align:middle line:90% I get into air. 00:09:00.110 --> 00:09:02.330 align:middle line:84% I think about Stan Lee and Spider-Man. 00:09:02.330 --> 00:09:05.010 align:middle line:84% With great power comes great responsibility. 00:09:05.010 --> 00:09:08.570 align:middle line:84% Holy cow, I can move cuttings out of the hole at 7,500 feet 00:09:08.570 --> 00:09:10.170 align:middle line:90% per minute. 00:09:10.170 --> 00:09:12.310 align:middle line:84% Jobs should be done under budget, on time, 00:09:12.310 --> 00:09:13.970 align:middle line:90% like super fast. 00:09:13.970 --> 00:09:16.450 align:middle line:84% We'll have cars going back over that road. 00:09:16.450 --> 00:09:19.270 align:middle line:84% But that's competent rock formations. 00:09:19.270 --> 00:09:20.550 align:middle line:90% That's no water. 00:09:20.550 --> 00:09:22.770 align:middle line:84% What happens when we start those waste streams? 00:09:22.770 --> 00:09:25.030 align:middle line:84% So then we start engineering solutions, 00:09:25.030 --> 00:09:30.030 align:middle line:84% either in mud or in foam, and we can start changing what we need. 00:09:30.030 --> 00:09:32.510 align:middle line:84% But the influence to that borehole wall, 00:09:32.510 --> 00:09:34.990 align:middle line:84% as we talk about that thermal conductivity test, 00:09:34.990 --> 00:09:40.170 align:middle line:84% as we talk about all of those pieces of influencing 00:09:40.170 --> 00:09:43.150 align:middle line:84% and minimizing that impact, come from us 00:09:43.150 --> 00:09:45.110 align:middle line:84% matching the right drilling method 00:09:45.110 --> 00:09:48.590 align:middle line:90% to what we're going to be in. 00:09:48.590 --> 00:09:52.050 align:middle line:84% So what do I need out of that drilling program? 00:09:52.050 --> 00:09:54.150 align:middle line:84% I need an efficient rate of penetration, 00:09:54.150 --> 00:09:57.270 align:middle line:84% because, let's face it, with the drilling companies that 00:09:57.270 --> 00:10:00.310 align:middle line:84% are in here, time and diesel fuel, 00:10:00.310 --> 00:10:03.350 align:middle line:84% regardless of our waste stream, because guess what, clients? 00:10:03.350 --> 00:10:04.930 align:middle line:90% You're a cogenerator. 00:10:04.930 --> 00:10:06.290 align:middle line:90% That's your waste stream. 00:10:06.290 --> 00:10:07.930 align:middle line:90% We're just managing it for us. 00:10:07.930 --> 00:10:10.990 align:middle line:84% Time and diesel fuel are the most expensive pieces 00:10:10.990 --> 00:10:12.950 align:middle line:90% for our projects. 00:10:12.950 --> 00:10:15.830 align:middle line:84% So I need to be able to have good rate 00:10:15.830 --> 00:10:18.430 align:middle line:84% of penetration and good production. 00:10:18.430 --> 00:10:22.030 align:middle line:84% Next, while doing that, I have to minimize the impact 00:10:22.030 --> 00:10:26.550 align:middle line:84% to the borehole and think about how I'm influencing 00:10:26.550 --> 00:10:27.810 align:middle line:90% that downhole geology. 00:10:27.810 --> 00:10:29.390 align:middle line:90% I talked about geology. 00:10:29.390 --> 00:10:31.990 align:middle line:84% Next to it, I said formation hydraulics. 00:10:31.990 --> 00:10:34.070 align:middle line:90% I want you to think about-- 00:10:34.070 --> 00:10:36.150 align:middle line:90% I was in wood shop. 00:10:36.150 --> 00:10:39.410 align:middle line:84% There's this really cute individual next to me. 00:10:39.410 --> 00:10:40.540 align:middle line:90% It's Mother's Day. 00:10:40.540 --> 00:10:42.580 align:middle line:90% We're building birdhouses. 00:10:42.580 --> 00:10:44.140 align:middle line:90% I want to ask her to prom. 00:10:44.140 --> 00:10:46.620 align:middle line:84% So I grab my birdhouse with the pine, 00:10:46.620 --> 00:10:49.280 align:middle line:84% and I drive all the screws in it, and I get it done. 00:10:49.280 --> 00:10:53.280 align:middle line:84% It fell apart two months later in Mom's yard. 00:10:53.280 --> 00:10:57.500 align:middle line:84% Amanda's birdhouse, I helped her predrill all the holes. 00:10:57.500 --> 00:10:58.300 align:middle line:90% We set it. 00:10:58.300 --> 00:10:59.600 align:middle line:90% We put the wood glue. 00:10:59.600 --> 00:11:01.600 align:middle line:90% Our geology's the same way. 00:11:01.600 --> 00:11:03.250 align:middle line:84% When we break that fracture gradient, 00:11:03.250 --> 00:11:06.000 align:middle line:84% just the same as if I drive a screw into this right 00:11:06.000 --> 00:11:08.740 align:middle line:84% now and split this table, I can putty that. 00:11:08.740 --> 00:11:09.980 align:middle line:90% I can do things to it. 00:11:09.980 --> 00:11:13.680 align:middle line:84% But I can't fix the damage I've done to Mother Nature. 00:11:13.680 --> 00:11:17.840 align:middle line:84% So beyond that, we get through those fragile subsurface 00:11:17.840 --> 00:11:18.740 align:middle line:90% formations. 00:11:18.740 --> 00:11:21.880 align:middle line:90% We get into water production. 00:11:21.880 --> 00:11:24.060 align:middle line:84% I want you to watch the news right now. 00:11:24.060 --> 00:11:26.680 align:middle line:90% Thank you. 00:11:26.680 --> 00:11:30.760 align:middle line:84% Princeton and Arizona came out with a connection 00:11:30.760 --> 00:11:33.220 align:middle line:84% between surface water and groundwater, 00:11:33.220 --> 00:11:35.400 align:middle line:90% talking about fossilized water. 00:11:35.400 --> 00:11:36.020 align:middle line:90% Holy cow. 00:11:36.020 --> 00:11:38.780 align:middle line:84% It's the drill guy talking environmentalism now. 00:11:38.780 --> 00:11:39.588 align:middle line:90% It's a weird time. 00:11:39.588 --> 00:11:40.380 align:middle line:90% Drill, baby, drill? 00:11:40.380 --> 00:11:42.120 align:middle line:90% No drill better drill. 00:11:42.120 --> 00:11:44.660 align:middle line:84% We need better people drilling professionally. 00:11:44.660 --> 00:11:49.580 align:middle line:84% So we are pumping fossilized water out of aquifers. 00:11:49.580 --> 00:11:53.300 align:middle line:84% That's going to take 10 years to 10,000 to 100,000 years 00:11:53.300 --> 00:11:54.340 align:middle line:90% to replace. 00:11:54.340 --> 00:11:57.380 align:middle line:84% So we save the planet by 2100, but we 00:11:57.380 --> 00:12:00.500 align:middle line:84% exploited all our groundwater and it went into the Atlantic. 00:12:00.500 --> 00:12:02.780 align:middle line:90% Did we save ourselves? 00:12:02.780 --> 00:12:05.820 align:middle line:84% So we have to understand, as we produce that water, 00:12:05.820 --> 00:12:07.560 align:middle line:90% and how much and the influence. 00:12:07.560 --> 00:12:09.520 align:middle line:84% But beyond that, as we go deeper, 00:12:09.520 --> 00:12:13.220 align:middle line:84% we have to start thinking about volatile gases, CO2, 00:12:13.220 --> 00:12:15.740 align:middle line:90% hydrogen sulfide, methane. 00:12:15.740 --> 00:12:21.580 align:middle line:84% And on that minimal impact, as we step back, dust, noise, drill 00:12:21.580 --> 00:12:22.340 align:middle line:90% solids. 00:12:22.340 --> 00:12:27.300 align:middle line:84% As we look at more campuses being done, man, Ball State, 00:12:27.300 --> 00:12:29.600 align:middle line:84% they didn't care how many dump trucks came through. 00:12:29.600 --> 00:12:32.460 align:middle line:84% Those were all Indiana farm kids. 00:12:32.460 --> 00:12:35.720 align:middle line:84% You go to Yale, you go to Fordham, 00:12:35.720 --> 00:12:37.440 align:middle line:84% and you start thinking about how we're 00:12:37.440 --> 00:12:39.800 align:middle line:84% removing cuttings and people are like, Why 00:12:39.800 --> 00:12:43.000 align:middle line:84% are there 10 dump trucks a day coming through here? 00:12:43.000 --> 00:12:45.840 align:middle line:84% We have to think about the impact to our neighbors. 00:12:45.840 --> 00:12:48.500 align:middle line:90% Finally, I need data gathering. 00:12:48.500 --> 00:12:51.240 align:middle line:84% I need real-time analysis of that subsurface 00:12:51.240 --> 00:12:55.420 align:middle line:84% as those formations change, as we have challenges, 00:12:55.420 --> 00:12:58.240 align:middle line:84% as we have loss zones, because I have to effectively 00:12:58.240 --> 00:13:01.160 align:middle line:84% be able to grout that so that I have the right influence 00:13:01.160 --> 00:13:03.840 align:middle line:90% to the loop. 00:13:03.840 --> 00:13:06.680 align:middle line:84% So the results of me doing this right, the hole's 00:13:06.680 --> 00:13:08.000 align:middle line:90% going to be open. 00:13:08.000 --> 00:13:09.780 align:middle line:84% Meaning, I can get product into it. 00:13:09.780 --> 00:13:11.040 align:middle line:90% It's going to be gauge. 00:13:11.040 --> 00:13:14.000 align:middle line:84% Again, my drilling influencing my geology. 00:13:14.000 --> 00:13:18.200 align:middle line:84% If we specify a 6-inch borehole, and we look at the cubic feet, 00:13:18.200 --> 00:13:20.720 align:middle line:84% or the cubic yards of grout we want to put in there, 00:13:20.720 --> 00:13:23.500 align:middle line:84% and we end up with this oblong boiler hole, 00:13:23.500 --> 00:13:25.220 align:middle line:84% we just saw what Garan talked about. 00:13:25.220 --> 00:13:27.120 align:middle line:84% We heard what Mark was talking about. 00:13:27.120 --> 00:13:28.280 align:middle line:90% We've screwed up. 00:13:28.280 --> 00:13:31.360 align:middle line:84% And now we have an ineffective system. 00:13:31.360 --> 00:13:32.620 align:middle line:90% So I need gauge. 00:13:32.620 --> 00:13:36.200 align:middle line:84% I need stable so that I can get in and out of it. 00:13:36.200 --> 00:13:40.240 align:middle line:84% It needs to be straight in the desired direction. 00:13:40.240 --> 00:13:43.820 align:middle line:84% And we need seamless product installation, loop to bottom, 00:13:43.820 --> 00:13:47.760 align:middle line:84% grout to top, so I can have efficient resource extraction. 00:13:47.760 --> 00:13:50.420 align:middle line:90% 00:13:50.420 --> 00:13:53.860 align:middle line:84% Sounds easy, but then we get into this situation right here. 00:13:53.860 --> 00:13:55.760 align:middle line:84% All different types of drill solids, 00:13:55.760 --> 00:13:59.420 align:middle line:84% how Mother Nature reacts to us, how our subsurface works. 00:13:59.420 --> 00:14:02.400 align:middle line:84% These spoils, as I get them out of the hole, 00:14:02.400 --> 00:14:05.420 align:middle line:90% How do I handle them? 00:14:05.420 --> 00:14:07.280 align:middle line:90% 6-inch borehole to 400 feet. 00:14:07.280 --> 00:14:09.080 align:middle line:90% It's 2.9 cubic yards. 00:14:09.080 --> 00:14:11.580 align:middle line:84% Oh, by the way, that's why we have three people on our drill 00:14:11.580 --> 00:14:14.180 align:middle line:84% crew, because there is a lot. if we're 00:14:14.180 --> 00:14:15.660 align:middle line:84% going to increase production, you 00:14:15.660 --> 00:14:18.220 align:middle line:84% need to be able to move this stuff away. 00:14:18.220 --> 00:14:23.940 align:middle line:84% 6-inch 850 foot hole is 6.17 cubic yards. 00:14:23.940 --> 00:14:25.920 align:middle line:84% So as we start thinking about this, 00:14:25.920 --> 00:14:27.900 align:middle line:84% How many dump trucks and back trucks 00:14:27.900 --> 00:14:30.900 align:middle line:90% am I bringing into this project? 00:14:30.900 --> 00:14:32.480 align:middle line:90% Loop installation. 00:14:32.480 --> 00:14:36.365 align:middle line:90% As we specify, two loops. 00:14:36.365 --> 00:14:39.540 align:middle line:84% The BU building with the Rygan, 1,500 feet. 00:14:39.540 --> 00:14:42.160 align:middle line:84% We think about all these different pieces. 00:14:42.160 --> 00:14:44.660 align:middle line:84% I need a good effective drilling program 00:14:44.660 --> 00:14:47.920 align:middle line:84% so I can have good grouting process. 00:14:47.920 --> 00:14:49.680 align:middle line:84% This loop should be in the center, 00:14:49.680 --> 00:14:52.180 align:middle line:84% and that trimming should be on top of it. 00:14:52.180 --> 00:14:54.420 align:middle line:90% But I'm really bad at paint. 00:14:54.420 --> 00:14:56.700 align:middle line:90% And this is what we get. 00:14:56.700 --> 00:15:00.800 align:middle line:84% So here's our tremie to bottom, our loop to bottom. 00:15:00.800 --> 00:15:04.280 align:middle line:84% My individual starts mixing the grout 00:15:04.280 --> 00:15:07.040 align:middle line:84% to the specified specifications that we need. 00:15:07.040 --> 00:15:09.500 align:middle line:84% The right amount of water, the right amount of bentonite, 00:15:09.500 --> 00:15:12.920 align:middle line:84% the right amount of graphite or sand. 00:15:12.920 --> 00:15:14.760 align:middle line:90% I start filling that borehole. 00:15:14.760 --> 00:15:16.920 align:middle line:84% As I fill that borehole, that tremie 00:15:16.920 --> 00:15:20.060 align:middle line:84% needs to stay 10 feet submerged in the grout 00:15:20.060 --> 00:15:22.980 align:middle line:84% so I have continuous grout column coming out. 00:15:22.980 --> 00:15:25.620 align:middle line:84% We talk about now we're going to leave the tremie in at bottom. 00:15:25.620 --> 00:15:26.960 align:middle line:90% Now we're not going to do this. 00:15:26.960 --> 00:15:30.260 align:middle line:84% I started my career after Yordy & Sons at Halliburton. 00:15:30.260 --> 00:15:33.540 align:middle line:90% I studied grout for 10 years. 00:15:33.540 --> 00:15:37.150 align:middle line:84% I'm bringing this grout column out of the hole with my tremie. 00:15:37.150 --> 00:15:38.400 align:middle line:90% And that's what I want to see. 00:15:38.400 --> 00:15:40.120 align:middle line:90% I want to see grout to surface. 00:15:40.120 --> 00:15:42.860 align:middle line:84% I need to effectively be able to look at that grout 00:15:42.860 --> 00:15:46.460 align:middle line:84% and know that I had a good column come out, 00:15:46.460 --> 00:15:48.400 align:middle line:84% that I didn't have channeling in that. 00:15:48.400 --> 00:15:50.100 align:middle line:84% As we have these discussions about, ah, 00:15:50.100 --> 00:15:51.880 align:middle line:84% it just needs to be 4 feet in the ground. 00:15:51.880 --> 00:15:52.660 align:middle line:90% No. 00:15:52.660 --> 00:15:55.700 align:middle line:84% I need to see this because this is protecting us. 00:15:55.700 --> 00:15:59.000 align:middle line:84% I need to see it come to surface. 00:15:59.000 --> 00:15:59.500 align:middle line:90% Why? 00:15:59.500 --> 00:16:02.380 align:middle line:84% Because I am replacing the native material that I just 00:16:02.380 --> 00:16:06.420 align:middle line:84% destroyed with something that meets or exceeds-- thank you-- 00:16:06.420 --> 00:16:08.680 align:middle line:90% our sealing capability. 00:16:08.680 --> 00:16:11.220 align:middle line:84% It's got to have a better standard. 00:16:11.220 --> 00:16:14.300 align:middle line:84% I need to ensure continuous contact between the loops 00:16:14.300 --> 00:16:15.040 align:middle line:90% and boreholes. 00:16:15.040 --> 00:16:17.380 align:middle line:84% We've got some brilliant individuals in here. 00:16:17.380 --> 00:16:19.700 align:middle line:84% You ask them what happens if we have a bad grout 00:16:19.700 --> 00:16:22.220 align:middle line:90% column and that air pocket. 00:16:22.220 --> 00:16:24.180 align:middle line:84% I need to completely seal the annular 00:16:24.180 --> 00:16:26.860 align:middle line:84% space to prevent comingling of aquifers 00:16:26.860 --> 00:16:29.520 align:middle line:84% and prevent surface contamination. 00:16:29.520 --> 00:16:31.500 align:middle line:84% As we look at these projects and we go hey, 00:16:31.500 --> 00:16:34.520 align:middle line:84% there's this open area, let's put a borefield here. 00:16:34.520 --> 00:16:36.320 align:middle line:90% Is it low land? 00:16:36.320 --> 00:16:37.600 align:middle line:90% Does it flood? 00:16:37.600 --> 00:16:40.520 align:middle line:84% My favorite question to ask when I show up on these projects 00:16:40.520 --> 00:16:44.120 align:middle line:84% is, Why isn't there a Starbucks here? 00:16:44.120 --> 00:16:47.000 align:middle line:84% If not, my greatest generation, my grandfather, they 00:16:47.000 --> 00:16:48.960 align:middle line:84% were really good at burying things, 00:16:48.960 --> 00:16:51.040 align:middle line:90% and we're going to find it. 00:16:51.040 --> 00:16:53.860 align:middle line:84% So I need to prevent that surface contamination. 00:16:53.860 --> 00:16:56.160 align:middle line:84% I need to comply with federal, state laws, 00:16:56.160 --> 00:16:58.480 align:middle line:84% and I need that thermal conductivity and borehole 00:16:58.480 --> 00:17:00.160 align:middle line:90% integrity to stay. 00:17:00.160 --> 00:17:02.640 align:middle line:90% This is my method. 00:17:02.640 --> 00:17:05.400 align:middle line:84% Check out my hour presentation, not abridged, 00:17:05.400 --> 00:17:06.560 align:middle line:90% so we can get into this. 00:17:06.560 --> 00:17:08.200 align:middle line:84% This is what I want to talk about. 00:17:08.200 --> 00:17:13.200 align:middle line:84% Success to a drilling project is managed through these points. 00:17:13.200 --> 00:17:17.319 align:middle line:84% And whether we're doing this all because of the climate change, 00:17:17.319 --> 00:17:20.359 align:middle line:84% we have to understand how this is changing our drill 00:17:20.359 --> 00:17:21.560 align:middle line:90% and build schedule. 00:17:21.560 --> 00:17:23.859 align:middle line:84% Next, other construction operations. 00:17:23.859 --> 00:17:25.859 align:middle line:90% What are our regulations? 00:17:25.859 --> 00:17:27.930 align:middle line:90% Location, location, location. 00:17:27.930 --> 00:17:30.070 align:middle line:84% Project timeline, and then neighbors. 00:17:30.070 --> 00:17:31.690 align:middle line:90% How am I sharing that site? 00:17:31.690 --> 00:17:34.610 align:middle line:84% How am I protecting Mother Nature? 00:17:34.610 --> 00:17:37.330 align:middle line:84% This is the reality of projects from downtown Los 00:17:37.330 --> 00:17:39.810 align:middle line:84% Angeles for George Lucas to right 00:17:39.810 --> 00:17:43.850 align:middle line:84% here just outside of Boston to a very tight location, 00:17:43.850 --> 00:17:46.450 align:middle line:90% urban church. 00:17:46.450 --> 00:17:48.970 align:middle line:84% This is what kicks our butt, everybody. 00:17:48.970 --> 00:17:50.870 align:middle line:84% If there was a slide to take a picture of, 00:17:50.870 --> 00:17:53.850 align:middle line:84% this is the one, because every time I get on a new call 00:17:53.850 --> 00:17:57.810 align:middle line:84% to troubleshoot a problematic project, I add to this slide. 00:17:57.810 --> 00:18:02.430 align:middle line:84% So if green, local geology should not be an issue. 00:18:02.430 --> 00:18:05.170 align:middle line:84% We should have an effective amount of test boreholes 00:18:05.170 --> 00:18:05.950 align:middle line:90% to know. 00:18:05.950 --> 00:18:09.590 align:middle line:84% So if I'm drilling a 600-hole project and I do two boreholes, 00:18:09.590 --> 00:18:12.850 align:middle line:90% is that a representative sample? 00:18:12.850 --> 00:18:13.730 align:middle line:90% No. 00:18:13.730 --> 00:18:15.750 align:middle line:84% That doesn't get us what we need. 00:18:15.750 --> 00:18:17.650 align:middle line:90% We need that subsurface data. 00:18:17.650 --> 00:18:18.930 align:middle line:90% What's hard? 00:18:18.930 --> 00:18:22.650 align:middle line:84% Man-made subsurface obstructions and contaminants, 00:18:22.650 --> 00:18:24.790 align:middle line:84% problematic sub subsurfaces as we 00:18:24.790 --> 00:18:29.750 align:middle line:84% get into fragile formations or water or artesian flow. 00:18:29.750 --> 00:18:30.648 align:middle line:90% And utilities. 00:18:30.648 --> 00:18:32.190 align:middle line:84% And those are the things that we have 00:18:32.190 --> 00:18:35.510 align:middle line:84% to be planning with the right qualified contractor. 00:18:35.510 --> 00:18:38.470 align:middle line:84% So if I have that right, qualified contractor and we have 00:18:38.470 --> 00:18:42.350 align:middle line:84% our pilot team right there, the pilot tutorial-- thank you-- 00:18:42.350 --> 00:18:43.890 align:middle line:90% watching Skillings drill. 00:18:43.890 --> 00:18:46.990 align:middle line:84% And that was a wonderful experience with all of them. 00:18:46.990 --> 00:18:48.870 align:middle line:84% What am I doing to choose this project 00:18:48.870 --> 00:18:51.030 align:middle line:90% if you call me as a contractor? 00:18:51.030 --> 00:18:54.310 align:middle line:84% Equipment availability, tooling, drilling method, 00:18:54.310 --> 00:18:57.690 align:middle line:84% compatibility with the location, site footprint, 00:18:57.690 --> 00:18:59.090 align:middle line:90% environmental demand. 00:18:59.090 --> 00:19:00.370 align:middle line:90% What is my timeline? 00:19:00.370 --> 00:19:03.910 align:middle line:84% What is the borefield design and borehole design? 00:19:03.910 --> 00:19:06.350 align:middle line:90% Project restoration and cleanup. 00:19:06.350 --> 00:19:09.150 align:middle line:84% That's a big piece, is managing our projects so 00:19:09.150 --> 00:19:11.910 align:middle line:84% that CSM or Clark or whoever you're 00:19:11.910 --> 00:19:13.682 align:middle line:84% using for your GC isn't like, you're 00:19:13.682 --> 00:19:15.390 align:middle line:84% going to drill another borehole and we're 00:19:15.390 --> 00:19:18.442 align:middle line:84% going to walk around in 18 inches of slop? 00:19:18.442 --> 00:19:20.510 align:middle line:90% What are my licenses? 00:19:20.510 --> 00:19:23.150 align:middle line:90% Am I IGSHPA accredited? 00:19:23.150 --> 00:19:25.530 align:middle line:90% These are all pieces. 00:19:25.530 --> 00:19:29.370 align:middle line:84% This is what we can do at test boreholes when we're surgical. 00:19:29.370 --> 00:19:32.470 align:middle line:84% And you can see, this project, we had snow and rain. 00:19:32.470 --> 00:19:33.190 align:middle line:90% It was Chicago. 00:19:33.190 --> 00:19:34.690 align:middle line:90% It was end of October. 00:19:34.690 --> 00:19:37.050 align:middle line:84% This is how we left the job site. 00:19:37.050 --> 00:19:39.570 align:middle line:90% So lessons learned. 00:19:39.570 --> 00:19:42.170 align:middle line:84% Every contractor is going to have an argument on why 00:19:42.170 --> 00:19:43.590 align:middle line:90% their method's the best. 00:19:43.590 --> 00:19:46.510 align:middle line:84% It's your choice how you move along with that. 00:19:46.510 --> 00:19:52.010 align:middle line:84% We need to optimize drilling every chance we can get. 00:19:52.010 --> 00:19:53.070 align:middle line:90% What do I want? 00:19:53.070 --> 00:19:54.950 align:middle line:90% I want qualified contractors. 00:19:54.950 --> 00:19:57.690 align:middle line:84% I want the right drilling method for the area. 00:19:57.690 --> 00:20:00.090 align:middle line:90% I want test boreholes. 00:20:00.090 --> 00:20:02.430 align:middle line:84% I want test wells that give us the right data. 00:20:02.430 --> 00:20:05.450 align:middle line:84% I want us to think about what we did successfully before, 00:20:05.450 --> 00:20:07.890 align:middle line:90% and how we loop and grout that. 00:20:07.890 --> 00:20:10.190 align:middle line:90% That was 21-ish minutes. 00:20:10.190 --> 00:20:10.910 align:middle line:90% Thank you, Stacy. 00:20:10.910 --> 00:20:11.785 align:middle line:90% Thank you, everybody. 00:20:11.785 --> 00:20:14.840 align:middle line:90% [APPLAUSE] 00:20:14.840 --> 00:20:21.000 align:middle line:90%
