That's awesome there's young people left that are using the brains that's givin to them to help the world instead of some woke ideologies! Hats off to Eavor

Stationed at Naval Air Station (NAS) Keflavik in 1979-80. The geothermal power plant extracted hot brine water and used heat exchangers to heat the fluid that flashed to steam to run turbines that produced electricity. Additionally the fluid was used to heat water for the heating district. So the NATO base got electricity and hot water to heat all the buildings. Finally, the plant dumped excess brine water into the lava field. That waste water was the origin of the Blue Lagoon which back then was an undeveloped pond with some stairs so that you could get in and out without slicing your feet up. PS - Hopefully, if there is an eruption, the new lava flow won’t destroy the plant!

Whenever big oil wants in on a renewable start up, you can pretty much forget about it. But i am amazed at how well it worked, the thermal current running for years as well as the ability to change output and even store up thermal capacity is awesome.

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

In the 1960s, New Zealand built its first Geothermal power station in Taupo (central North Island). Our family moved there and Dad worked on the first two bores and the station itself as a carpenter. The science was so new that we were the first, Government funded and built, full scale base load generation plant in the world. To see the fields today is fascinating, the hundreds of kilometers of pipes cover many square km of farmland. I would love to see this new tech in other parts of less Geothermal activity, here in NZ.

This will significantly reduce the cost of drilling to even greater depths than Eavor is currently doing and make their energy production truly the lowest LCOE (levelized cost of energy). Hope that Europe can adopt this technology as fast as possible so that Putin can be made redundant and everyone can enjoy clearer air at the same time. Exciting times.

The next step is to investigate Quaise Energy and AltaRock. Quaise is commercializing a drill bit that melts its way through basement rock and leaves a glass lining behind that obviates need to install a casing (50% of drilling cost). They hope to be able to drill 20km holes and get 450-500C temp. AltaRock in Seattle will use their technology to drill the first hole in Oregon.

Some years ago I worked in the 'oil patch'. I must agree the ability to drill precisely was amazing back then, and today I only assume it is more so. ... On of my employers was Amoco, before purchased by BP, in exploration 20Million was a typical exploration well, so 100Million is not that much money considering they put billions into exploration annually. When I was working the Exploration would find a revisor, guess as to its size then sell it to the 'production' company that would put in many well in a field and operate and produce it for many years. Eventually most fields get sold to secondary production companies (smaller oil companies).. Oh the production company typically sells the oil to their own or others refineries who the sell the refined products to wholesalers or retailers. Every step along the way each company was normally required to make their own 'profit', so the true level of profit in these companies was often obfuscated, IMHO.

Here in Australia I am sure we have many potentially great locations for Geothermal Power generation, the proof is where we have hot mud springs coming to the surface and Artesian wells/bores drilled all over the place with hot water bore drains running for kms, I believe we have capped most of them for now. There is more heat source power below us than we can use, id be very happy to see governments throw money at this tech, its probly one of our greenest solutions.

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.

Thermosiphons are old technology. The Model T Ford used that method to cool its engine with no water pump at all. The radiator does have forced air from the engine through its fan, and the temperature difference alone is sufficient to cause the water to circulate. Look at old trucks and other cars from that era and you will see the radiator is mounted quite high compared to cars with water pumps. Cars from my childhood also tended to have thermosiphon effects even when there was a water pump. Like the hole in the bumper under the radiator for a crank to start the car if the electric starter failed, cars were made with redundancy to continue working back then. Today if the computer dies so does the modern car.

Yes! Closed loop Rankine cycle with lower quality heat. Low boiling point fluid in a closed loop driving a high pressure turbine. Very little maintenance, no emissions, no water usage, can be done anywhere, and at much lower depths. Makes perfect sense!

canada has some smart people who are bringing leading technologies to the world ..

The hot water at the surface boils an organic liquid which drives a vapor turbine that turns a generator to make electricity. Similar to how a solar pond power generator works using an ammonia engine. Ammonia absorbs heat from the hot salty water at the bottom of the pond to drive the ammonia engine.

Imagine a porous rock, like a sponge. There are a lot of down hole tools. When I was designing tools for Schlumberger the limit was 200c and approx. 25,000 ft. Good job.

In Alberta where Eavor is located Eavor could build a pilot plant near the tar sands to generate the electricity that the tar sands requires to process oil.

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.

It is a misunderstanding that in Iceland all geothermal power stations use areas were the hot water or steam reaches the surface. The bigger geothermal stations use boreholes around 3 km deep to find steam. Places were you find hot water at 3 to 5 km without any sign on the surface, are rather more common than expected. Icelandic have done work in other countries finding those places and exploit them. Iceland has also done a bit of work on binary power stations. You can run binary cycle down to about 80°C. Geothermal is really underutilized, especially at it can be used as base power 24/7/365. There is also possible to use fracking technology where you have hot dry rock. You drill holes and frack the rock, you pump down water in one hole and get steam up in the other hole.

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.

As the depth of wells being drilled increases, the weight of the drilling mud must be progressively increased in order to prevent the open section of borehole from collapsing and to provide sufficient hydrostatic pressure to prevent the well from kicking or blowing out. Strings of casing are also run as needed to eliminate problems with shallower sections of the borehole.

It's a everlasting powersource. Whatever the explorationeconomics. Though i think that conventional drilling is out of time. New innovations are needed to.drill deeper, faster, cheaper. I believe in the near future.

This is great, what is their current LCOE (levelized cost of energy)? What is the up-front cost, average oil well is $1-2 mil just to drill and at least in the western US is about 500 -1,500 ft deep?

an other good reason to test this in Germany is that Germany is midtier geologic active. So it is hard enough to get to the heat that innovation is necessary. But within those regions that don't really do Geothermal because it is to hard it is one of the easiest. Therefore that Region seams to me to be a good testing ground.

So if you want to go for domestic energy, that leaves hydro, geothermal and wind. Today geothermal provides about 65% of primary energy, hydro about 20% and wind is in it's infancy here. That leaves 15% to hydrocarbons, mainly for transport.

Natural heat from the Earth is called Eorthermal Heat. No need for water in the rock. The challenge is to recover the heaat in an economic manner, so as to recover the capital costs of the drilling and installation of facilities.

The innovation is in transferring the heat from the hot water to another liquid and using the gaseous form of that other liquid with a lower boiling point to turn the turbine in a closed loop.

I wonder if being able to switch from using the heat directly in winter to generating electricity in summer would increase the efficiency enough to make the switching worth it.
