Exploration Activity: Tracer Testing At Raft River Geothermal Area (1983)

Exploration Activity Details
Location Raft River Geothermal Area
Exploration Technique Tracer Testing
Activity Date 1983

Usefulness not indicated
DOE-funding Unknown

 
Exploration Basis
To develop chemical tracing procedures for geothermal areas.
 
Notes
Two field experiments were conducted to develop chemical tracer procedures for use with injection-backflow testing, one on the fracture-permeability Raft River reservoir and the other on the matrix-permeability East Mesa reservoir. Results from tests conducted with incremental increases in the injection volume at both East Mesa and Raft River suggests that, for both reservoirs, permeability remained uniform with increasing distance from the well bore. Increased mixing during quiescent periods, between injection and backflow, at Raft River suggest an area near the well bore that has a hydrologic character different from the far well bore environment.
