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 degrees 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.
