Eavor Technologies | The First Scalable Form of Clean Baseload Power 

I can see it now. The 'green' extremists wanting to shut down the drilling because it is bad for the environment just as they believe fracking is. I'm sure they will try it even though there is no fracking here. The only Eavor borrows from the oil industry is the deep drilling tech. Even then, they are developing some of their own unique technology. Go for it kids! (I call them kids because I'm 77 years old.)

Yes, but they’ll still have to be price competitive with PV + battery, which is getting cheaper all of the time.

@@TheAnticorporatist They probably don't have to exactly meet the LCOE of PV+battery because they are a firm generator. ("firm" means it never stops) They are a clean source of baseload power, which is critical for having an efficient grid.

Only if our representatives got involved and made this a government paid program so that power would be free of charge to the world!! would that be too much to ask?

Not everything is about price. The low cost of Solar is irrelevant at night. LCOE of geothermal has to be taken into account along with the LCOE of sun and wind energy production because these systems work in tandem. No?

Could reuse the wells! Just gotta figure out how to plug, flush, and seal them

@@AmandaComeauCreates. Not that easy.

Re: Closed Cycle Geothermal. I first saw this presented at UCLA 50 years back. Some of the problems then were drilling equipment unable to tolerate temperatures at those depths, as well for heat exchangers, & control precision to locate & maintain such equipment at those depths & highly adverse conditions. Finally, plus a great investment opportunity! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gV92QFDb5qQ.html

Yeah.... New jobs for old fields and you generate continuous employment for decades at least.

@@themusicgaragetmg2330the old fields will generate and grow new oil over time

A little over 50 years ago, I lived in an apartment that was heated with that type system. It was nice and warm in winter even if the electricity went off.

​@danielhanawalt4998 That is fascinating . Where was this ?

@@aptorres01 I first saw them in an episode of This Old House long ago.

Big oil has been known to suppress new technologies so they can keep a stranglehold on the energy sector.

you weren't joking about the dumb part.

Agree re the European situation. In the UK we have the Government suggesting fracking as a solution to Putin. This would be a great fast fix.

They don't even need to go very deep. 50C return water would be plenty warm enough for heating. Winter heating is one of the greatest uses of energy in Europe.

Is there any risk of fracturing the bedrock and creating earthquakes or other geological problems?

@@privatemale27 it makes you wonder, after the heat has been used to create electricity, could the hot water be pumped to the surrounding area to heat homes before being sent back down the well.

@@jonwelch564 That is pretty common in other geothermal installations. They don't need to use the same water either. They can use a heat exchanger to heat treated city water.

The world's first commercial geothermal power station was built in Italy in like 1911.

hah. end-eavor

A Model T probably couldn't produce much heat, so a heat syphon might have been sufficientl. Old cars used to boil over when I was a kid, I don't have that kind of a problem now days. My work van has just had it's first problem at 87,000 miles, the exhaust injector has just failed causing it to go into limp mode (not a real issue, but Ford want you to get it fixed). Old cars cant compete because modern technology beats it hands down.

Standard drilling equipment like the drill bit and the pipe used to rotate it can handle temperatures (1600+ degrees F) way above what their target temps are. When you start getting into directional drilling tools, downhole motors to spin the bit without spinning the pipe, and their tools used to intersect the two boreholes, those are the items that really don't have very high temperature ratings due to the moving parts, electronics, and rubber seals (probably 300 to 400 degrees F or 150 to 200 degrees C). Any technology they have for hotter temps than those they will have to develop if they haven't already. Mostly that means developing non-rubber seals and making sure the materials used in tight tolerance applications have similar coefficients of thermal expansion. Also developing electronics that are either non-silicon based or are encased in some type of dewar flask style insulation.

@@kevinstone7723 thanks for the info!! Very succinctly put.

They are so past that. They don’t utilize drills in the deep digging- they use plasma.

I'm concerned that we could sink so much heat that we could cause an accelerated cooling of the Earth and cause environmental issue for future generations.

@@VetforVets LOL, you have no idea how hot and plentiful geothermal energy on the earth is. We're literally on a mostly molten planet with a super thin crust.

@@gurumage9555 Who would of ever thought that Cow Stinkers would ever contribute to the Green House Gas problem. Never say "never" my friend.

@@VetforVets LOL you are literally comparing a very thin layer of gas (our atmosphere) with a very large ball of molten rock (our Earth). Not comparable in the least.

I assume they would pump a grout in to seal the holes in the rock.

@@jonwelch564 except wanting to line the well not plug it since if the drill a 6 inch hole a half inch lining cuts the flow to 25/36 of the volume and a one inch lining would cut the flow to 16/36 of the drilled 6 inch hole. Interestingly the larger the diameter the easier fluid flow but relatively less surface to volume so it does not warm as fast

@@jeffbybee5207 guessing, would the grout seep into the porous rock and not block the hole? I don't know, just thinking out loud.

After a well has been drilled, open-hole wireline logs are run to identify productive formations. These logs accurately indicate the borehole caliper, minerals, porosity and types of fluid present in each formation. Another wireline tool can then be run to measure the permeability and retrieve samples of the fluid. In productive intervals with low permeability and containing high viscosity fluids, downhole reamers are often used to enlarge the original borehole. Doing this increases the productive capability of an interval and minimizes production damage to the borehole. These reamers have extendable arms lined with PDC cutters that fold downward along the sides of the tool. It is placed in the BHA (bottom hole assembly) and is designed to pass through the previously drilled borehole. When it reaches the desired reaming depth, mud pumps provide the hydraulic pressure necessary to force these arms outward and make contact with the borehole while the drill string is being rotated and moved up and down. This procedure continues until a larger borehole has been created in each zone of interest. The arms on these reamers are pulled back onto the tool when the pump pressure drops, thus allowing it to be moved to ream another interval or brought back out. Centralizers are attached to casing as it is being run down the well to assure the casing will be held away from the borehole in the areas that will be cemented. This is to assure cement will be able to bond with the casing in order to seal the annulus of the well. A cement float shoe and sometimes float collars are placed in the string of casing as it is being run in order to control where cement will be pumped into the annulus of the well. After all of the casing has been run, a calculated amount of a customized cement blend is pumped down the casing, followed by a measured amount of water sufficient to displace it in the casing, thus forcing the cement into the annulus of the well. The string of casing is hung from the derrick of the drilling rig and isn’t moved until the cement has harden, and then a wireline bond log is run to confirm it has bonded with the casing. If not, then a cement squeeze may be necessary to assure the well has been completely sealed between the borehole and casing. This is extremely important to protect fresh water aquafers. Many times cement is pumped over a productive zone and later perforation guns fire multiple holes through the casing and cement into the formation. When a productive zone is near the bottom of the well, the casing is often run 30 to 40 feet past the porosity in order to provide room to easily complete the well, then cement is pumped through a cement float collar located above the productive zone so that it won’t be covered by cement. Drilling mud prevents cement from going very far past the float collar, instead it is forced to flow up the annulus of the well. The drilling mud will then be removed during the completion work, therefore enabling production to be optimized.

@@jonwelch564 if casing is placed in all sections of the drilled area and somehow sealed to the main up and down pipes then heat can be collected with out fluid loss or contamination but the casing it's self would slow heat transfer. I would guess a plastic liner could be pulled through then pressurized but still a 6 inch Dia bore hole seems really limiting fluid flow and heat collection

Wiki has quite a good article on Australia... en.wikipedia.org /wiki/ Geothermal_power_in_Australia

This would cut into the profits of certain industries. They do their best to shelf or hide this kind of stuff from the public. Tesla is a good example. His discoveries ruffled feathers.

I believe it is currently about 20milion to produce 2mw

I agree but what happens if they spend a lot of money zapping a very deep hole, only to plunder into a magma chamber which shoots magma upward and fills the hole (and potentially destroys the equipment too)? It's a risk but in the end, I think it's worth it.

@@WeDeserveBetterNow Apparently there have been cases of drilling hitting magma, and because the walls of the hole are enough colder than the magma, the magma sets near the bottom of the hole.

That's good news. Hopefully mm waves can be used in the very near future to dig super deep!

Some of the companies are using Ammonia instead of water because it boils at a lower temp. No battery required as the earth is a thermal battery.

Geothermal is available anywhere regardless of location. some areas are closer to hot rock. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-PtQmGPmyLA0.html

I work in Electricity. It can be done basically anywhere, some regions are just more suitable than others. Also the Rockies are quite old mountains, unlike Iceland.

@@hightechredneck8587 Thing is, there's lots of hot springs in the Rockies of Canada, so crust is much thinner than eg great lakes area.

@@lengould9262 That is moreso due to the location of the faults and the push from the pacific tectonic plate, similar case as LA but their case is less extreme.

She did kind of address that question. The average change in temperature is 20c per km. That is every where. So this can be deployed almost anywhere. I haven’t heard an answer to life span. Perhaps because the tech is evolving. The original bore casing was a type of rock pipe. Sounds like they are trying different things. I would say the heat is for ever and it’s more the lifetime of the “radiator “. 50-100 years. Maybe more.

I'll just add that apart from that minor misunderstanding Anna and Christopher did a great job explaining this technology. I've been keeping up with it off and on for over a decade now and am glad to see that this pilot project is working out well and that things are about to move ahead.

Anywhere that can be drilled for oil or gas can be drilled for heat. stability helps but isnt needed, there are ways to mitigate that.

It seems humanity will have to collapse before change is taken seriously.

@@mtn1793 Civilization will definitely need some fairly serious pressure and it is probably going to get worse before it gets better, but I wouldn't go so far as assuming that it will necessarily require a full blown collapse.

Sounds like they are still perfecting the system but even if they had it all worked out. If every drilling rig on the planet was working on this, it would take decades.

I don’t think a single loop will generate 10 MW. Probably they will have multiple loops for higher power levels.

@@billorcg7779 how many loops then? A million? I cannot understand how they have got this far without doing some basic calculations on heat transfer and power flux.

Hawaii runs 20 binary air cooled machines to produce 30 Mw, or about 1.5 Mw per unit. Even with a multi path “radiator” down there, each tube must be the same length as the others (or different diameters) in order to equalize the flow thru each n be efficient. Water, like people, will always take the path of least resistance.
