Dr. Thrash has served as Chief Executive Officer of eCORP, predecessor companies and affiliates since 1985, having formally joined in 1982. For more than 30 years, he has continuously lead the development, acquisition and disposition of the Company’s E&P (primary and enhanced oil recovery and natural gas production), gas storage and power projects, as well as its often unique, highly sophisticated financing initiatives. Dr. Thrash developed the Company’s current global business plan as an outgrowth of this platform.

Owning, operating and integrating three classes of assets (upstream natural gas and oil; midstream natural gas; and downstream electric power) which in the aggregate, have constituted many billions of USD investment to-date and allowed the company to uniquely manage E&P risk by coupling it with natural gas storage development in select geologic settings. He has positioned the company as a noted “green” developer through projects exhibiting profound environmental care and concern in their construction and operation in addition to innovating adaptive “green” technologies. The company’s latest technology (ecorpStim) uses pure home grade propane without water or chemicals – an alternative to traditional hydraulic fracturing.

Dr. Thrash has served in numerous advisory roles and presented to a broad range of US and international regulatory agencies (such as the U.S Federal Energy Regulatory Commission, Comisión Reguladora de Energía of Mexico, United Nations Economic Commission for Europe, and Alliance Nationale de Coordination de la Recherche pour l’Énergie) as well as to public forums on scientific and energy related topics. He also has had a distinguished academic and research career. He is a Phi Beta Kappa graduate of Trinity University in San Antonio, Texas with a Bachelor of Science in Chemistry. Dr. Thrash obtained a M.D. and trained at Baylor College of Medicine, Houston, Texas.

Audis C. BYRD


Mr. Byrd brings to the team strong technical knowledge and experience, including high pressure/high temperature completions and shale resource plays, as well as onshore, offshore and deep-water projects globally with an excellent interdisciplinary background in both well construction and completion practices. Mr. Byrd, a former COO of GasFrac Energy Services, led the company’s introduction of LPG Fracturing “Waterless Stimulation” technology into the US Market and grew the US division revenue to $13,500,000 per month in two years. Over the course of his 30-plus year energy services career, including 25 years at Halliburton Energy Services and 5 with EOFG Resources, Inc., he served on National Petroleum Counsel (NPC) Study to evaluate the Natural Gas Market in the US and update the NPC 1999 study out to the year 2025 for the US Secretary of Energy. Additionally, while leading a 22-person team to improve stimulation operational efficiency, this team developed the first fully remote controlled fleet of stimulation equipment using mobile computing and high-speed LAN communication, a 6 million dollar development project that was on time and on budget.

Mr. Byrd further directed a team to improve stimulation designs, which was the birth of a Stimulation Optimization process (SIGMA) to use the well construction and completion data to optimize well completions and led the development of a real-time software package to analyze Mini-Fracs to optimize Stimulation treatments-this process reduces stimulation cost and improves well production. He holds a BS in Mechanical Engineering from Louisiana Tech University and is a Registered Professional Engineer in Oklahoma. Mr. Byrd holds 12 US Patents and has authored 10 Society of Petroleum Engineers Papers and 4 Trade Journal Articles.




Drawn from his 30 year career with industry leaders including Chevron, Arco, Clayton Williams, S.A. Holditch, Ely, Falcon, Petroleum Consultants, Halliburton Energy Services and Norton Proppants, Mr. Stephen Schubarth has expertise spanning fracture treatment design, analysis, and supervision; formation evaluation through log and core analysis; evaluation of “tight” gas reservoirs; pressure transient analysis of oil and gas wells; and reservoir evaluation and computer simulation.

More specifically, Mr. Schubarth developed an evaluation process for multi-layered reservoir completions to determine both stimulation effectiveness and reservoir permeability, worked with Operating companies in “Unconventional” Oil & Gas plays to provide innovative stimulation designs to improve recovery of hydrocarbons, both domestically and internationally and designed and developed the concept for a new proppant product.

Mr. Schubarth has testified before the Texas Railroad Commission as an expert witness in “tight” gas sand applications and has authored more than 20 technical papers, the vast majority of which have been peer reviewed.
