Who We Are

Larry B. Crain

President and Chief Executive Officer

As a graduate of the University of Texas at Arlington, Larry Crain accumulated broad business insight during his terms for Texas Instruments, in the 1970s and also with Vice President for National Comp Associates, where he was top producer for five years. Throughout his 20-year oil and gas career, Crain has focused on the ownership, operation and funding of oil and gas prospects/properties generated by PetroMax Operating Co., Inc., which he founded in 1988.

As Operating Partner, Crain’s management of daily operations allows him to maintain the successful relationships he has amassed with oil and gas industry partners, private estates, and individuals participating as non-operators with PetroMax Operating Company. Crain’s knowledge of the cyclical nature of the oil and gas industry strengthens his belief that now is the best time to capitalize on the relationships PetroMax Operating Company has with the majors and large independents.

Larry is married, the father of two sons and a daughter, and has three grandchildren.

Mike Hoover

Operations Manager

Mike Hoover has accumulated over 25 years of personal experience in the oil and gas industry including petroleum land management, geological evaluation and interpretation, open-hole and cased-hole engineering, and production management, including intrastate pipeline operations.

While completing his college degree at Abilene Christian University, Hoover worked at Burns Oil and Gas as an assistant to a former Texas Railroad Commissioner (District 7B) in a regulatory compliance consulting field. Following graduation, he worked in his father's oil and gas exploration business, Dymar Corporation, becoming educated in all areas of the business, from office operations to drilling, completion, prospect evaluation, regulatory compliance and general field operations. Hoover eventually chose to pursue his own place in the industry as a self-employed prospect generator, specializing in the Gulf Coast area, resulting in annual drilling prospects for his personal account and his industry partners.

Larry Crain invited Hoover to join forces in 1989. As Operations Director for PetroMax Operating Co., Inc., Hoover accomplishes a wide variety of tasks, including prospect generation and evaluation, geological prospect review, well-planning (legal, drilling through production, sales), post-completion operations (product marketing, re-completion implementation, and land management), and management of all operational aspects of Trans-Sabine Pipeline Co., which includes 25 miles of intrastate pipeline systems.

Mike is married, and is the father of a son and a daughter. As an alumnus, he serves on the Board of Trustees of Dallas Christian School and actively volunteers as the school’s tennis coordinator.

Flynt Gaines, CPA

Chief Financial Officer

After Gaines’ graduation from Abilene Christian University, he served over a year of active duty with the United States Air Force. Gaines continued with a reserve career until 1989, when he formally began his professional accounting career.

Gaines’ first seven years of accounting were spent with Sanders-Chance Corporation, Republic Gypsum and the University of Texas at Dallas. His experiences required a wide range of expertise such as automated accounting systems, job-costing systems, staff auditing, general ledger responsibility, internal audit preparation, due diligence on acquisition targets, and general management of accounting staff.

By early 1990's, Gaines moved into the rarefied area of SEC Corporate Accounting and Reporting, and the preparation of internal audits along with internal and external financials, including EBITDA reporting and special projects. These responsibilities for the Southland Corporation also required 1 ½ years in Japanese financial reporting.

As his career progressed, Gaines developed his own firm, Flynt Gaines & Associates, Inc. He also began his own small natural gas company, Basin Gas, Inc., active in the Barnett Shale of Denton County. Eventually Gaines redirected his professional efforts, coupling his accounting career with PetroMax Operating Company. Gaines marshaled in a new era of financial capability, providing advanced corporate accounting, advanced joint interest accounting, updated computer, and accounting and office systems. His responsibility for financial reports, internal financial controls and information systems is vital to the company.

Flynt is married, and is the father of two daughters.

Robert Sparks

Director of Business Development

Robert Sparks has over 25 years experience in the generation, acquisition, exploration, development, and operations of oil and gas properties. As a graduate of Lamar University, his professional career has focused on the business development and marketing side of the industry for independent oil and gas companies.

Beginning in 1977, Sparks served in the positions of President, Vice President of Sales and Marketing, Director of Business Development, and Business Development and Marketing Consultant to independent oil and gas operators. He has weathered the ups and downs of the industry as a 'hands on' participant, and has created a winning business model for every phase of the industry. Under Sparks’ direction, independent oil and gas companies have increased their market presence, located capital sources to fund prospects, enlarged exploratory and development budgets, strengthened communication from field to partners, and improved overall visibility in an industry once ruled by the majors.

Sparks’ professional journey also includes prior achievement in retail and wholesale distribution, business development and consulting, oil and gas development, business and personal counseling, ministry development, and fund-raising and capital acquisition for privately-held companies. Additionally, he earned two Master’s Degrees in separate fields of study.
