A Hydrogeologic Study to Optimize Steamflood Performance in a Giant Oilfield: Kern River Field, California

摘要

The stratigraphic interval above the Round Mountain formation in the Kern River field contains four confined aquifers. Two of these confined aquifers are composed of sandstones in the main and transition zones of the Santa Margarita formation, and the remaining two are composed of sandstones in the lower and middle zones of the Chanac Formation. Above the confined aquifers is one regional, mainly unconfined aquifer in sandstones of the upper Chanac Formation and lower zones (U-lower K2) of the Kern River Formation. This unconfined aquifer is overlain by several perched aquifers in sandstones of the upper zones (upper K2-C) of the Kern River Formation.
