Gasbuggy postshot hydrologic investigations in GB-3

Technical Report ·
OSTI ID:5125264
The Gasbuggy postshot well GB-3 was drilled, logged, and cored to investigate the effects of the nuclear explosion on the Ojo Alamo aquifer. Postshot investigations in other wells (GB-ER, GB2-RS, and 10-36) indicated that hydraulic communication had been established between the aquifer and the gas reservoir. Hydrologic tests in GB-3 indicated that the permeability of the aquifer was increased by factors of 2 to 4 over preshot values at a radial distance of about 630 ft from the shot point. Investigations of the aquifer response to pressure changes in the reservoir, water levels in wells 10-36, GB-3 and the tubing annulus in GB-ER suggest that the main, if not only, point of hydraulic communication between aquifer and reservoir is through casing breaks in GB-ER.
