In a job drawing heavily on the best resources and technology in the oil industry, the No. 1 Gomez-Eaton gas unit, located 7 miles northwest of Fort Stockton, Texas, ran the largest carbon dioxide fracture known. Marsh's No. 1 Gomez-Eaton gas unit was drilled to the Ellenburger, where dry gas wells average 22,500 ft and temperatures run to 350 F, requiring innovative and sometimes risky fracture techniques. Since its inception in the late 1960s as a gas field, the Gomez trend has yielded over 2 tcf of gas from its deep, naturally fractured Ellenburger dolomite. The frac cost approx. $600,000, a small figure compared to the potential $40 to $100 million recovery which eventually may be expected from the formation. To successfully run the frac job, 1,200 tons of CO/sub 2/ was required, along with 105,000 gal acid (HCl-acetic acid mixture adjusted to 20% HCl equivalent).
