Abstract:

The Santa Barbara Channel region is the westerly part of the Transverse Ranges geomorphic province of California. It includes the submerged seaward extension of the Ventura basin and the continental slope to a distance of 70 mi offshore. A nearly complete post-Jurassic sedimentary section is present. The total section ranges in thickness from 19,200 to 67,600 ft. Potential reservoir rocks range in thickness from 4,600 to 25,400 ft. The section is 30% arenaceous.

Geologic structures are generally west trending. Anticlinal trends with steeply dipping flanks (up to 75°) are prominent. Numerous nearly vertical lateral faults and high-angle reverse faults are also prominent. Vertical displacements in excess of 10,000 ft and lateral displacements of more than 3 mi are recognized.

Twenty-three oil or gas fields are present in the region. Of these 5 have been discovered on Federal lands in the past 2 years, but only 1 was being developed in August 1970. Cumulative production from all fields is more than 1 billion bbl of oil and nearly 300 Bcf of gas.

Statistical approaches to the determination of original oil in place in the region have yielded varying results in the magnitude of 25-35 billion bbl. However, comparisons with other sedimentary basins of the California Coast Ranges indicate that an estimate of 10-15 billion bbl of oil in place is more likely to be in the right order of magnitude.
