Gas reserves growth boosts Sacramento basin

Operators have discovered 153 gas fields in the Sacramento basin of northern California ( Fig. 1 [203,575 bytes] ). This study includes data from 114 fields; gas fields with less than 1 bcf of cumulative recovery were eliminated from the tabulations. These 114 fields have a combined probable ultimate recovery of 9,546.3 bcf of gas. The fields produced a combined 75.5 bcf in 1996. Cumulative production to Jan. 1, 1997, is 9,027.2 bcf, and remaining reserves are estimated at 519.1 bcf. Including
