After graduation in 1951, Forrest A. Garb joined Socony Mobil Oil Company and was assigned to the Magnolia Petroleum Company operations in Kansas, Texas and Louisiana. He then served two years in the U.S. Air Force during the Korean conflict, during which time he researched foreign propellants and lubricants. He rejoined Socony Mobil Oil Company in 1954 and was assigned to offshore drilling programs, working with drilling fluid control and high-pressure well completions.
From 1955 to 1957 he served as a field and reservoir engineer in Socony Mobil's eastern and western Venezuela divisions. His responsibilities included formation and reservoir evaluation, development and exploration programs. He was a company representative on unitization engineering committees and directed reservoir pressure surveys and well workover programs.
Mr. Garb joined the staff of H. J. Gruy and Associates, a petroleum engineering consulting firm, in 1957. Mr. Garb attended computer programming schools and the advanced reservoir engineering course for petroleum industry personnel at Texas A&M University and introduced the use of digital computers to the Gruy company operations. Mr. Garb authored some of the first petroleum engineering computer programs used by the industry. He was elected vice president of H. J. Gruy and Associates, Inc. in 1959, Executive Vice President in 1963 and President in 1973. He became president of The Gruy Companies, Inc., an international consulting firm, with its founding in 1975. In his capacity as president, Mr. Garb contracted, performed and supervised over 12,500 projects ranging from simple hydrocarbon property evaluations to sophisticated reservoir simulations. On December 31, 1986 The Gruy Companies, Inc and H. J. Gruy and Associates Inc. were reorganized into Gruy Engineering Corporation and became a subsidiary of a public corporation. Mr. Garb served as President of the combined firms.
On February 1, 1988 Mr. Garb founded Forrest A. Garb & Associates, Inc., a privately-owned consulting firm dedicated to providing the highest ethics, technology and service to the client.
Mr. Garb has written more than 50 technical articles for technical journals, including the series in Petroleum Engineer International titled "Property Evaluation with Hand-Held Computers" and the series in World Oil magazine titled "Waterflood Calculations for Hand-Held computers." At the request of the Society of Petroleum Engineers (SPE), he updated and re-wrote two chapters on estimation and valuation of reserves for the SPE Petroleum Engineering and Production Handbook.
As a Distinguished Author for SPE during 1985-1986, Mr. Garb authored a paper for the Distinguished Author Series titled "Oil and Gas Reserve Classification, Estimation, and Evaluation." He was again designated as a Distinguished Lecturer by the SPE during 1986-1987, and lectured on risk and uncertainty in evaluating hydrocarbon producing properties at more than 35 domestic and overseas locations. In June, 1988, he was elected to Distinguished Membership in the SPE. In January, 1990, he authored his second paper for the Distinguished Author Series titled "Which Fair Market Value Method Should You Use?" He was the 1995 recipient of the Society of Petroleum Engineers' Economics and Evaluation Award for contributions to petroleum engineering. He is the recipient of the American Institute of Mining, Metallurgical, and Petroleum Engineers (AIME) 2001 Mineral Economics Award "For significant contributions to the development of practical petroleum economic models and computer programs and for efforts to share his knowledge with the industry.
Mr Garb presented a series of seminars to petroleum industry personnel in the People's Republic of China in November 1979, and was elected chairman of the National Petroleum Committee of the National Council for United States-China trade. In February, 1989 Mr. Garb served as an expert witness on behalf of American oil companies before the Iran-United States Claims Tribunal in the Permanent Court of Arbitration, The Hague, Netherlands. His technical testimony was based on more than three years of engineering studies regarding claims presented by the American oil companies resulting from the expropriation of their properties in the Persian Gulf by the government of Iran. Mr. Garb has participated as a technical expert in a number of international and domestic arbitrations or litigations involving some of the largest hydrocarbon accumulations in the world.
Mr. Garb is a member of the Society of Petroleum Engineers, and served as President of the Society of Petroleum Evaluation Engineers in 1997. He continues activity in the industry societies He has been a member of the Association of Computing Machinery, and is a member of the Petroleum Engineers Club of Dallas, the Dallas Geological Society, and the American Association of Petroleum Geologists. He is a Charter Member of The American Institute of Minerals Appraisers. He is listed in numerous Who's Who publications, Including Who's Who in World Oil and Gas. He is a licensed professional engineer in the state of Texas.
