Title: Yorba Linda Oil Field, Orange County, California: ABSTRACT

Author(s): James C. Benzley

Article Type: Meeting abstract


The Yorba Linda field was discovered in 1930 but received its greatest development after 1937. The originally developed area is a faulted homocline producing from lenticular Repetto sands. The "Shallow" and "Repetto" pools were discovered in 1954.

The "Shallow" pool is structurally similar to the original area, but produces 12°-13° oil from beds of Pleistocene or uppermost Pliocene age. The trap is a combination of faulting and overlap. A rather unique condition exists in the presence of top water in the structurally higher wells of the "Shallow" pool. This water is theorized to be of possible meteoric origin and may have retarded discovery of this fairly considerable reserve.

The "Repetto" pool is on a gentle east-west-trending arch. Correlations are commonly difficult in a short distance and great variation occur in well potentials due to faulting and erratic stratigraphy. Some of the production faults in the Repetto area seem to have little or no displacement in the shallow beds. The main producing zone is near the upper-middle Repetto contact. Two other producing zones are present a little higher in the section--the "Third Intermediate" and the "Hall" sand. Both are lenticular and are probably channel sands.

The Carlton area was discovered in 1956 and has been very spotty and disappointing. Production is from the Repetto with faulting and pinch-outs both important. It is possible that this area is structurally related to the East Coyote field.
