Consider Minute 50:49 on presentation, there you have some field data. Based on these data you have "gross energy" or power and Net energy, you have flow rates and bottom hole pressure. One thing is clear, the graphs have gross power around 2.5 MWe and net power around 1.5 MWe. Even the EGS project generate 3.4 MWe the capital cost for this energy is enormous (my opinion). 3.4 MWe and 63 kg/sec water is only 8133 BTU electricity (2.133 kWh) per every barrel water injection/produced as steam. EGS projects are great to make money for companies who take subsidies (grants), but not to generate cheep afordable energy.
Good lecture as usual Dr. Horne. I can't recall what city, but one recently allowed their public gas utility to switch to a district heating business model. Interested to see how that turns out.
Do the temperature contours follow uplifted/intrusions of granite as implied by the "Geologic structure" slide? If so, are there advantages to drilling at the base of steep gradients of granite such as in the Eastern Sierras & Central Oregon?
What I see coming is a national electrical distribution grid. The USA is about two thousand miles wide with four hours of time zones. One or more east/west DCHV power line would load balance across the nation. Morning solar in the east afternoon solar in the west. Geothermal all of the time. Wind and other sources as available. Behind the meter and system batteries would provide load balancing. One for all and all for one.
Oil and gas fracked wells traditionally use sand and the like to hold open fractures against pressure, w relatively low flow, a 1-2 kg per sec. How are a fractures held open w 60-80kg/sec working to remove sand?
Thank you, we can prevent these phenomena like cyclone by using this hot seasonal atmospheric condition and geothermal in summer happen in surface of coastline, there are many countries in coastline with seasonal hot weather and water condition by using this energy not only is economy but also reduce global warming like Japan, China, Mediterranean countries, Iran, Mexico, Us, Canada, (Africa and Arabian countries....) that I mentioned in my profile.
Pumping power? PE alone, m*g*h of 80kg/sec, depth 7km is 6MW, w say 60% eff pump, 10MW. Can that ever pay? Once again, much nearer surface, hotter rock seems to be required, ie rare geothermal conditions using traditional, not enhanced methods.
@@mohammadaljubran2456 I’m aware; I don’t think it significantly applies. You know better? The injection wells and recovery wells and generation system with steam expansion in between would have to somehow be a single phase system w little compressibility over 10km. I don’t see it. I do know some earlier egt pilot projects a few years ago were net loss power.

@ Yes it’s store window operation imo to pretend something is being done about intermittent solar-wind build outs, when gas is what’s really being done. But that need will keep $ flowing to stunt/prototype EGS projects. Eventually they’ll be like the old abandoned failed tidal turbine projects, a big pile of rusting machinery in the middle of nowhere.
@ applying heat extraction at scale can influence the soil in hard to predict ways from earthquakes to sink holes to ground aquifers it’s just not worth it solar is dirt cheap and so is energy storage now

With regard to running counter to solar timing -- could you soak daytime power into injecting hot water to store the thermal energy?

got any on Advanced systems?, as in enhanced vs advanced ...geothermal systems.. : )

How much water loss?
The MIT feasibility target was 80kg/s, and 7000N deep, yes? Blue Mountain was 300M deep per this demonstration, yes?
Blue Mountain is about 3000 m deep.

Think of thermosiphon effect
