Title: Elwood Field: ABSTRACT

Author(s): J. D. Traxler

Article Type: Meeting abstract

Abstract:

The Elwood field is located along the coast line, 10 miles west of Santa Barbara, California. Less than 500,000 barrels of heavy oil has been recovered from the Rincon Shale, almost 100 million barrels of 28°-36° A.P.I. oil from the Vaqueros Sandstone (a shallow-water transgressive beach sandstone), and more than 3 million barrels of 33°-38° A.P.I. oil from four zones of the Sespe Formation (non-marine sandstone with siltstone interbeds). Productive area is slightly more than 690 acres. Early offshore wells were drilled from piers and later wells were directionally drilled from the adjacent sea cliffs.

Complex east-west-trending reverse and lateral-type faults parallel the Elwood anticlinal structure on the north and south. One minor cross-fault in the western productive area is not an effective barrier to oil movement. Naples offshore field, located 2 miles west on the Elwood trend, and La Goleta gas field, located 4 miles east on the Elwood trend, are characterized by geologic conditions similar to those in the Elwood field.
