Geophysical History of the La Gloria Field, Jim Wells and Brooks Counties, Texas

Abstract

This paper presents a historical record of the geophysical activity in the area of the La Gloria Field. The successive stages of geophysical exploration were: Torsion balance survey 1934–1935; correlation reflection seismograph survey 1936; dip reflection seismograph survey, 1938; correlation reflection seismograph survey, 1938; gravity meter survey, 1943–1944. The discovery well, Magnolia’s Sam Maun No. 1, was drilled and completed in 1938–1939, producing initially 165 barrels per day of 65° gravity distillate and 5,646,000 cubic feet of gas through a 5/16 inch choke. Oil and gas in the La Gloria Field are being produced from sands in the Frio formation of Oligocene age. There are a number of sands producing gas‐distillate. Several flank wells produce oil. The field has been unitized and a cycling plant is engaged in processing the gas‐distillate.
