Mr. Whitaker has over 38 years of extensive, multidisciplinary experience with both major and independent oil companies encompassing numerous aspects of exploration for, and development of, carbonate, clastic, and unconventional reservoirs. For 16 years he ran his own oil company in the Illinois Basin where he conducted exploration and development programs in addition to owning and operating 24 wells. Mr. Whitaker has a well-earned reputation for utilizing proven methods and developing innovative concepts to improve production through development, EOR/IOR, and exploration projects. His extensive experience includes: business management, project economics, operations, geology, petroleum engineering, geophysics, detailed mapping of subsurface and surface geology, prospect generation and development, reservoir characterization, EOR/IOR design and implementation, computer-enhanced mapping, and acreage acquisition. He has authored several publications regarding oil and gas development and exploration and has won awards for his presentations at regional and international technical conferences.
