The Dry Gas Zone was defined by US Naval Petroleum Reserve No. 1 Engineering Committee (1957) as ''/hor ellipsis/all sands bearing dry gas above the top of the Lower Scalez marker bed. The term is used to include the stratigraphic interval between the Scalez Sand Zone and the Tulare Formation - the Mya Sand Zone. The reservoirs in this upper zone are thin, lenticular, loosely cemented sandstones with relatively high permeabilities.'' Other than the limited Tulare production in the western part of the field, the Dry Gas Zone is the shallowest productive zone in the Elk Hills Reserve and is not included in the Shallow Oil Zone. It is Pliocene in age and makes up approximately eighty percent of the San Joaquin Formation as is summarized in Exhibit TL-1. The lithologic character of the zone is one of interbedded shales and siltstones with intermittent beds of various thickness sands. The stratigraphic thickness of the Dry Gas Zone ranges from 950 to 1150 feet with a general thickening along the flanks and thinning over the crests of the anticlines. The productive part of the Dry Gas Zone covers portions of 30 sections in an area roughly 10 miles long by 4 miles wide. 4 refs.
