Injection/Production Behavior in Cymric Field Cyclic Steam Wells, and their Implications to Surface Expressions and the Kinematic Evolution of the Diatomite Reservoir

Abstract Oil Production on the west side of the San Joaquin Basin in California includes from Miocene/Pliocene formations dominated by diatomaceous sediments which have very high porosity, very low permeability and high oil saturations, often produced using cyclic steaming. The wells are drilled in dense patterns as typically the fracturing and heating impacts of cyclic steaming are contained within 10's of feet of the wellbore.
