, becoming chief of the Division of Mines there in 1912. He returned to the U.S. in 1916, and in 1918 joined
Humble Oil & Refining Co. as the company's first geologist. Prior to that time the company had treated the search for
oil as largely a hit or miss operation without scientific exploration. But Pratt, joined by 10 more geologists during 1918–19, proved that geology was an important factor in finding oil. Among the most notable early contributions made by Pratt and his staff were geological studies that led to the correct interpretation of the structure of the huge Mexia Field, discovered in October 1920 in

of the land over the oil field. Pratt was tasked with the investigation of this novel phenomenon and produced a report in which the subsidence was definitively attributed to the extraction of petroleum. In 1926, together with D. W. Johnson, he published these findings in a scientific paper. By this year, after about ten years of active pumping, most of the productive area of the field had subsided three feet, and the submerging of the facilities had already become obvious to field operators.

research and development, and the manufacture of a
refraction seismograph recording in the field. Pratt served as Humble's chief geologist and later director, and vice president. In 1937, he joined
Standard Oil Co. (Humble's parent firm in New Jersey), once again rising to director, executive committee member, and finally, vice president, a position he held until he retired from the company in 1945.
In the same year that he had joined Standard Oil, the company named one of their tankers after him, the SS Wallace E Pratt.
Petroleum geologist
After retirement, Pratt served on the
National Security Resources Board for two years and began a long career as a consultant geologist. Pratt wrote more than 100 geological papers during his lifetime, including ''Oil in the Earth'', one of the most widely read books in his profession. An often repeated quote from this book is, "Gold is where you find it, according to an old adage, but judging from the record of our experience, oil must be sought first of all in our minds." There was a limited amount to find, though: at the University of Kansas, Pratt gave a lecture "Oil in the Earth", where he speculated that the total amount of oil in the United States was 100 billion barrels.
