In 1994 Pacific Operators Offshore, Inc. sought and won a United States Department of Energy Class III cost sharing project to perform reservoir studies leading to the drilling of a trilateral redevelopment well in their Carpinteria Offshore Field in the Santa Barbara Channel of California. The intent of the project was to increase production and extend the economic life of this mature field through the application of advanced reservoir characterization and drilling technology, demonstrating the efficacy of these technologies to other small operators of aging fields. Two study periods were proposed; the first to include data assimilation and reservoir characterization and the second to drill the demonstration well. The initial study period showed that a single tri lateral well would not be economically efficient in redevelopment of Carpinteria's multiple deep water turbidite sand reservoirs, and the study was amended to include the drilling of a series of horizontal redrills from existing surplus well bores on Pacific Operators'Platform Hogan. After some 42 months of study, during which all existing field data were digitized, wells were re-related elated, digital petrophysical studies were performed, fault blocks defined and reservoir geometries identified and mapped, and redevelopment targets identified and graded, four target zones in two fault blocks were selected for initial redevelopment. Two pilot wells were drilled in the selected fault blocks to verify adequate remaining oil saturation, resulting in the re-assessment of one of the target zones. For economic efficiency, these wells were completed as conventional infill producers. Immediately following, drilling was commenced on the four horizontal wells. Each was completed in its target zone using slotted liner. Producing intervals averaged around 500 feet in length. In total, the initial redevelopment project added 760 barrels per day, dramatically increasing the production from Platform Hogan and extending the economic life of the field.
