The Geothermal Reservoir Well Stimulation Program (GRWSP) group planned and excuted two field experiments at the Raft River KGRA during 1979. Well RRGP-4 was stimulated using a dentritic or Kiel hydraulic fracture technique, and Well RRGP-5 was stimulated using a conventional massive hydraulic fracture technique. The analyses and results of these stimulation treatments are presented. Both stimulation experiments at Raft River were technically successful; however, the post-stimulation productivity of the wells was disappointing. The productivity indices (PI) of Wells RRGP-4 and RRGP-5 were found to be 0.6 gpm/psi and 2.0 gpm/psi, respectively. Pressure transient data indicate an area of reduced transmissivity or limited entry near these wells and an area of high transmissivity (greater than 500,000 md-ft/cp) located at some distance which acts as a constant pressure boundary. The major fault lines near these wells are suspected of being the major source of the geothermal fluids. Further long-term testing is needed to confirm this fact.
