How enhanced geothermal works

Project Red, Nevada: 2.35 km down · 990 m laterals · 16 stages · 169 °C out · 3.5 MW

Follow one well pair from first drilling to power: two horizontal wells, sixteen fracture stages between them, and water looping through hot rock to a power plant at the surface. Pick a part to isolate it, see through the rock, or go down to the fractures. Every number on the page comes from one model.
