Mr. Allison was born and raised in Alice, Texas. He received his Bachelor of Science, Mechanical Engineering from Texas Tech University in 1986 and his Masters of Business Administration in 1988 from Texas A&M University. San Isidro was one of Mr. Allison’s first consulting clients and he has been responsible for San Isidro’s engineering and operations since 2009.

As an Offshore Operations Training Engineer, Mr. Allison completed the year long ARCO Oil and Gas Company Engineering Development Program that included schools and projects associated with the major engineering departments in 1989. Projects he worked on consisted of planning and supervising offshore workovers, transferring platforms, and evaluating and drilling offshore development prospects. He then became a Production Coordinator for Arco where he supervised operations of two South Texas fields (Donna and San Salvador) which were comprised of three production facilities and more than 60 oil and gas wells. He installed and implemented automation equipment to reduce operating expenses and ease information transmission.

Mr. Allison spent almost two years as an Operations and Analytical (Reservoir) Engineer from 1990 through 1991. He developed overall asset management plans for two ARCO operated fields in South Texas (Northeast Thompsonville and S. Aviators) and two co-owner operated fields (St. Charles Ranch and Pledger). His responsibilities included budgeting, reserve estimation, and well evaluations and proposals along with participating on teams that reviewed purchases, sales, submittals, and farmouts.

Mr. Allison shared responsibility for the start-up and overall performance of a small independent company, Alyndson Oil and Gas, Inc. of Alice, Texas from 1991 to 1994. Alyndson purchased and operated producing properties as well as participated in and operated joint drilling prospects. His responsibilities included engineering and economic evaluation, operations supervision, as well as capital acquisition.

From 1994 to 2003, Mr. Allison worked for Killam Oil Company, Laredo, Texas. For six years he was a Production Manager/Engineer. He managed oil and gas operations of Killam Oil’s 1993 acquisition of Duval County Ranch. During that time, he increased production from 350 BOPD to 1000 BOPD through drilling, workover, and acquisitions. He also was responsible for all engineering and operations in the area, which consisted of primarily shallow, stripper-well production. In 2000, Mr. Allison became Operations/Engineering Manager, responsible for managing all of Killam Oil Company’s engineering and operations in South Texas. The company operated approximately 350 producing oil and gas wells and as well as an active exploration and development drilling program, primarily in Webb, Duval and Zapata counties. The company also actively participated in joint ventures and acquisitions.

From 2003 through 2008, Mr. Allison was the Operations/Engineering Manager for U.S. Enercorp, Ltd., San Antonio, Texas. He was solely responsible for managing engineering and operations of the independent oil and gas company in South Texas. The company grew from a relative unknown to become the largest gas producer in San Antonio, Texas, producing approximately 60 MMCFPD. The company actively generated, sold, and operated exploratory and development prospects, primarily in McMullen, Duval, Jim Hogg, Zapata, DeWitt, Lavaca, Goliad, and Starr counties. Typical projects ranged from 10,000 feet to 15,000 feet. The company also had an active horizontal drilling program in the San Juan Basin of New Mexico.

In 2008, Mr. Allison founded Wishbone Energy, Ltd., an independent oil and gas company which acquired operated and non-operated working interests in exploratory and development prospects, as well as producing properties. Wishbone Operating, LLC is a consulting and operating company that manages all oil and gas design and operations for itself and other companies.
