Abstract
As of January 1, 1977, approximately 1,450 billion cubic feet of gas and about 670 million barrels of oil* are estimated as remaining recoverable reserves in 11 of the 12 fields in the Outer Continental Shelf (OCS) off Southern California. No estimates were made for the unnamed field on lease P-0234 because well testing was not sufficient to allow a reasonable assessment. Of the 12 recognized fields, only two are producing and none is completely developed. Limits of many of the fields will be further defined by anticipated additional exploratory drilling. Original recoverable reserves in 11 fields are estimated to have been approximately 1,530 billion cubic feet of gas and about 830 million barrels of oil.
Reserve estimates for nine fields were based on individual volumetric reservoir studies. Decline curve and volumetric analyses were used to estimate reserves in two fields. The estimates of original and remaining reserves are reported as one total for oil and one for gas within the Southern California OCS.
*The term "oil" as used in this report includes crude oil, condensate and gas-plant liquids.
