James Mayer

Founder & CEO

James Mayer has a broad entrepreneurial background in energy, management, project development, corporate finance, operations, sales and marketing. His diverse, multi-disciplinary background provides a unique platform for innovation, creative problem solving, and wealth generation in the oil & gas business. Mayer’s previous work experiences have provided unique and valuable background for the development of a large oil and gas company. While earning his MBA at the Wharton School, in 1980 Mr. Mayer formed an acquisitions, divestiture and financial consulting firm specializing in the coal industry, A. J. Mayer International, Inc. For about a decade he advised on M&A and financial transactions and undertook assignments for a broad array of domestic and international clients, including Fortune 500 companies and privately owned concerns. In the 1990s Mr. Mayer organized, owned and successfully operated Pennsylvania Coal Company, Inc. In this capacity he was responsible for all facets of a coal exploration and multi-operations surface mining company. Pennsylvania Coal Company’s slogan was “Dedicated to Integrity and Excellence, Concerned for Our Communities and Our Environment,” and Mayer and his staff lived by this creed. The result was that in the company’s history it never had a material environmental or safety violation and made many friends with regulators and members of the communities it operated in—all while achieving high productivity, low cost, and strong profitability. Pennsylvania Coal had its own exploration drilling team that cored coal and rock samples to identify and evaluate coal reserves. In the coal industry Mayer gained valuable experience in geology, engineering, land, operations (including drilling), project development, logistics, and personnel management. All of these coal industry experiences have translated well into the oil & gas business. In 2005, after selling his coal business, Mr. Mayer returned to the energy consulting business. His emphasis expanded from coal to include gasification, biomass, oil & gas, combined heat and power, and CO2 solutions with emphasis on CO2 EOR. One of Jim’s clients was former Speaker of the House Newt Gingrich, and he continued to act as an energy adviser to Speaker Gingrich through his 2012 Presidential campaign. Jim Mayer has an MBA with a dual major in finance and accounting from the Wharton School at the University of Pennsylvania, and a B.S. in business administration from the University of Maine. In association with his past investment banking activities, he was licensed by the National Association of Securities Dealers (the NASD) as a general broker dealer “representative” and as a broker/dealer “principal” for direct participation programs including limited partnerships.

Arlen Edgar, P.E.

In Memoriam – Prominent Oil & Gas Investor, Petroleum Engineer, and Executive

Arlen Edgar was a respected senior member of the Midland, Texas, oil and gas community, a successful independent oil & gas investor, and an experienced petroleum engineer and executive. He was an oil industry investor for over three decades. Arlen Edgar began his career with Pan American Petroleum in 1957 as a junior petroleum engineer. After four years, he joined Leibrock, Landreth, Campbell and Callaway, a consulting engineering firm, becoming manager of the consulting division. At the same time, he served as secretary and a director of Canada-based Kanata Exploration and southern Louisiana-based Offshore Exploration Company. In 1967, Mr. Edgar joined Robert M. Leibrock’s new company, Tipperary Land and Exploration, which was involved in farming, cattle, shrimp fishing and hard minerals. While working for Tipperary, he spent time exploring Australia, discovering a major bauxite deposit there. After four years with Tipperary, Arlen joined Western States Producing Company as general manager of the San Antonio-based oil & gas company’s Midland office. In 1973 Arlen Edgar decided to branch off on his own. He started out doing petroleum engineering consulting and gradually began participating in drilling deals as an investor, and buying oil wells, production royalties, and oil & gas mineral rights.
