The South Houston salt dome was discovered by the Stanolind Oil and Gas Company, by use of the torsion balance, in May and June, 1934.
The structure was confirmed a few weeks later by reflection seismograph, by the Independent Exploration Company, under contract to the Stanolind.
The original gravity anomaly was partly obscured by the influence of a large regional gravity-minimum area, commonly referred to as the “Pearland regional minimum.“
The discovery of the South Houston salt dome is unique in respect to the accuracy with which the domal uplift was localized and the very limited amount of work necessary to find it.
Subsequent drilling confirmed the salt dome, and oil was discovered in commercial quantities immediately thereafter.
