Passage: DeGolyer opened a petroleum geology consultancy in 1914, moving to Montclair, New Jersey to work in New York City in 1916. In 1919, while working as a consultant to the British entrepreneur Lord Cowdray, DeGolyer negotiated the sale of the El Aguila company to Royal Dutch Shell. In the same year, DeGolyer organized the formation of the Rycade Oil Company as well as the Amerada Petroleum Corporation for Lord Cowdray, rising to become general manager, president, and chairman from 1929 to 1932 DeGolyer left the firm in 1932, but remained with Rycade, which was established to explore salt dome oil deposits through 1941. As a geophysical consultant with Rycade, DeGolyer made the first torsion balance survey in the United States at the Spindletop oilfield. An oilfield found by DeGolyer on behalf of Rycade at Nash, Texas was the first oilfield anywhere to be discovered using geophysics. From 1925 DeGolyer established the Geophysical Research Corporation as a subsidiary of Amerada to develop reflection seismology techniques originated by J. Clarence Karcher and Eugene McDermott, leaving in 1932 to move to Dallas, Texas. DeGolyer provided financial support for the 1930 establishment of GRC's successor, Geophysical Service Incorporated. GSI went on to spin off Texas Instruments.

DeGolyer was also associated with the Atlatl Royalty Company from 1932 to 1950 and the Felmont Corporation in 1934.
