Harry G. McMahon III
Vice President
Mr. McMahon joined Mr. Van Dyke’s companies in December 1999 as a consultant and advanced to provide leadership in exploration, operations and new ventures.
Mr. McMahon started his career with Range Oil Company, Inc. where he functioned as a prospect generator and field operations supervisor. Playing the south-central area of Kansas, Mr. McMahon’s successes included stratigraphic and structural trapping mechanisms and in terrigenous and carbonate reservoirs in prospects generated without the aid of seismic.
Later he joined BEREXCO Inc. as a geologist both generating prospects and providing technical support for development and exploitation drilling and workovers. Mr. McMahon supervised drilling operations of wells in Kansas, Nebraska, and Texas as well as providing geotechnical support for a broad range of non-operated properties throughout the Lower 48 of the United States. While at BEREXCO, the company grew to become the one of the largest oil producers in the state of Kansas operating over 4,000 wells in numerous states. Mr. McMahon also used his business acumen to develop, from scratch, and EH&S policy for BEREXCO. In addition to policy development, Mr. McMahon oversaw the field implementation of EH&S policies and personally presented policy rollouts in field offices.
In 1997, Mr. McMahon joined TransTexas Gas Corporation as Acquisitions Manager with responsibilities for both domestic and international venture acquisition and divestitures. Mr. McMahon’s initial responsibility was to assist in the company’s divestiture of its Lobo (Wilcox) Trend assets which successfully closed at nearly $1.4 billion. While at TransTexas, traveled extensively in the US and abroad to acquire properties and prospect that conform to corporate strategic goals. Prospects acquired and drilled in Mr. McMahon’s tenure all targeted Wilcox reservoirs in south Texas and enjoyed 100% commercial success.
Mr. McMahon has been involved in the discovery and development of a number of significant fields in the U.S. mid-continent and Gulf Coast. Discoveries range from subtle combination traps in the Lansing-Kansas City carbonates in southwestern Nebraska to successful development of fluvial Morrow sandstones in the Hugoton Embayment of Kansas to Wilcox and Yegua sandstones of south Texas and to halotechtonic related combination traps in Miocene and Oligocene sandstone in the salt domes of southern Louisiana.
Mr. McMahon has a Bachelor’s of Science Degree in Geology (1980) from the University of Kansas, and a Master’s in Business Administration (1995) from Wichita State University.
