About 5, gpm of geothermal water is produced from four production wells, generating 11 MW e of power before being reinjected back into the reservoir through four injection wells. The objective of the project was to take a sub-commercial injection well, RRG-9 ST1, and hydraulically and thermally stimulate it to improve its injectivity to commercial levels.

The Raft River Geothermal Exploration Well No. 1 (RRGE-1), drilled to a total depth of 4, feet (1,m), approximately feet (m) into basement rock, encountered F ( C) bottomhole temperatures with an artesian flow.
