This visual comes from International Finance Corporation’s new “Success of Geothermal Wells: A Global Study” report and depicts the success of a geothermal power plant well by the geology.
GEA’s Ben Matek observed from the data that “It appears larger scale volcanic features have the highest modal capacity of about 6 MW, while sedimentary basins have the smallest modal capacity at about 3 MW,” though he acknowledges the authors’ note that data fluctuations make “definite conclusions” difficult.
The authors hypothesize that older volcanic structures are more fractured than other geology types, “and so permeability of the reservoir is higher, allowing greater flow of geothermal fluids.”
