Excerpt: ... THE OIL FIELDS. SUBDIVISIONS. For convenience of discussion the Coalinga district has been roughly divided into five fields or regions, and these into lesser subdivisions or areas. The major subdivisions are as follows: (1) The Oil City field, lying in Oil Canyon near the north end of the district; (2) the Eastside field, embracing the territory northeast of Oil Canyon and including Anticline Ridge; (3) the Westside field, extending southeastward from Oil Canyon as far as Alcalde Canyon; (4) the Kreyenhagen field, which includes the Jacalitos and Kreyenhagen hills, Reef Ridge, and the territory southward to the Kings County-Kern County boundary; and (5) the region of the Kettleman Hills, extending from the Guijarral Hills southward to the gap separating the Kettleman from the Lost Hills. CONTOUR MAP. EXPLANATION. The contour map of the Coalinga field (Pl. II) shows the structure, boundaries of the more important geologic formations, and certain culture, such as towns, section lines, and a few roads. The structure in the productive territory is indicated by contours showing the distance above (marked by a plus) or below (marked by a minus) sea level of the base of the "Big Blue" or top of zone B in the Eastside field and of the top of zone B in the Westside field. The contour interval is 100 feet. By means of this map the direction and amount of dip of the strata in the oil-bearing formation may be calculated for any point in the field, and the depth to the various productive sands or zones may be approximated for most parts of the territory. USE OF THE MAP. Suppose it is desired to find the probable depth below the surface of the first productive sand at the middle of the north line of SE. sec. 24, T. 20 S., R. 14 E. An examination of the map will show t...
