The Richland gas field was the second field discovered in northeastern Louisiana. The discovery well was completed in December, 1926, 10 years later than the discovery of the Monroe gas field, 10 miles northwest. Gas is produced in an area of more than 75 square miles at depths ranging from 2,320 to 2,500 feet in Gulf Cretaceous beds composed of red gumbo, gray tuffaceous sand, and sand. There is also a gas horizon several hundred feet below the regular "pay" and in the upper part of the Lower Glen Rose formation. The structure on the base of the Midway clays immediately above the pay horizons is that of an irregular dome elongate north and south, with the least dip away from the field located at the northwest side and toward the Monroe field.

The drilling practice has been to set casing at 2,300 feet, then to drill to 2,450 feet and bring in the well. This custom necessitated, because of the nature of the pay horizon, the development of a method of tubing the wells under the existing high open flows and pressures which at the beginning were 1,125 pounds. By January 1, 1934, the field had produced 368 billion cubic feet of metered gas from 240 wells.

The marketing of production is now fully under way with gas from the Monroe and Richland fields moving through pipe lines to Atlanta, St. Louis, New Orleans, Houston, and intermediate cities.
