Report: Raft River Geothermal Exploratory Hole No. 3

Raft River Geothermal Exploratory Hole No. 3 (RRGE-3) is an exploratory hole with three directional legs, drilled to depths ranging from approximately 5,500 to 6,000 feet into intruded quartz monzonite basement rock of the Raft River valley of southeastern Idaho. The goal of the Raft River Geothermal R and D program is to determine the feasibility of developing and utilizing medium temperature (300°F) geothermal resources for power generation and nonelectrical applications. This well was drilled to provide data to further investigate and evaluate the geothermal reservoir, as well as to optimize the location of possible future resource and/or injection wells and to develop methods to reduce the cost of geothermal wells. The drilling and completion of RRGE-3 is described and the daily drilling reports, drill bit records, descriptions of the casing, cementing, logging and coring programs, and the containment techniques employed on RRGE-3 are included.
