Field exploration activities initiated by GeoProducts Corp. in 1977 culminated in the successful completion of a deep production well in Sept. 1981. The well was drilled to a depth of 5823' and completed in a fractured, dominantly granodiorite lithology. A broad fault zone with associated fracturing occurs at approximately 5300'-5335' and serves as the main production zone. Well testing has indicated a highly productive well with no immediate boundaries. Long term testing was conducted at a constant artesian flow rate of 670 gpm with a maximum downhole temperature during flow of 251 F. The thermal fluid is a Na-SO/sub 4/-Cl type of low salinity. Various geothermometers suggest that the fluid originates from a reservoir in the 275-310 F range. Further study and refinement of the system model is ongoing in preparation for future deep drilling.
