Vice President - Geoscience Technology with primary responsibility for the research and development, technical service, and organizational capability of the geophysical, geological, and petrophysical functions at Chesapeake Energy. Additional external role - one of two Chesapeake Energy representatives as a Board of Director member for the company Wireless Seismic.

VP Geosciences Northern Division with primary responsibility for MidContinent, Anadarko and Arkoma Basins.

Houston, Texas And Calgary, Alberta

Chief Geoscientist for BP’s North America Gas Business Unit with primary responsibility of overall geoscience discipline health• Manage Onshore US New Ventures Team - geoscience technical specialists responsible for developing BP’s unconventional reservoir strategy. Team developed new basin and fairway screening techniques for shale gas plays and evaluated all basins in North America. BP recommended options resulted in a resource booking of > 1.0 B barrels of oil equivalent Non Proved resources in three years. • Coordinate the North America Gas exploration strategy and annual plan execution for conventional exploratory drilling, leasing and seismic expenditures with annual budget ranging from $100 - $125 MM.• Lead technical assurance reviews for BP exploration and production projects and external new business opportunities• Coordinate geoscience technology R&D needs, manage technology ‘seed’ budget for experimentation and field trials. Positive results include: 1. Re-defined petrophysical pay definition in tight gas sands and shales 2. New petroleum systems workflows for unconventional reservoirs 3. Test of cableless 3D seismic acquisition techniques• Consult on database management issues for wellbore, core, biostrat and seismic data• Conduct organizational capability assessment and feed inputs into global college recruiting program • Represent NA Gas at the BP Global Geoscience Advisory Forum – steering committee for developing and editing BP’s three volume Geoscience Handbook distributed to more than 1,500 subsurface staff worldwide• Coach and mentor new hire geoscientists

Houston, Texas

Resource Manager responsible for the business performance planning, reservoir management and technical assurance for the Anadarko Basin Asset drilling and completions budget of ~ $150 MM• Led the exploration focus for the asset in multiple fairways (Atoka, Granite Wash, Morrow and Hunton formations). Asset team added > 2 TCF of Non Proved resources in the Mountain Front area of the Anadarko Basin• Worked with industry partner to develop a commercially successful horizontal drilling program in the Cleveland Fm.• Created a low cost business strategy with industry partners to drill wells on HBP acreage position in areas where we were operationally inactive. Program produced the best economic performance in the business unit year on year.• Represented NA Gas to BP’s Global Subsurface Technology Advisory Board

Houston, Texas And Tulsa, Oklahoma

Geoscience Technology Manager with primary role of providing management of technology areas relating to Biostratigraphy, Petroleum Systems, Sedimentology and Sequence Stratigraphy, Seismic Modeling and Rock Properties Analysis• Provided leadership in the delivery of integrated, cost effective technology solutions for Business Unit problems• Led an organizational re-design of the Amoco E&P Technology Business Unit and implemented a process-centered model within six months. The new organization achieved a $23 MM improvement in financial performance within the first two years and received the Amoco Chairman’s Award for Business Excellence in 1997 and 1998.• Served as an extended team member to the Amoco Prospect Quality Team and responsible for the geoscience technical assurance of Amoco’s worldwide exploration prospect portfolio. • Led Amoco’s worldwide Sequence Stratigraphy User Group as Network Leader and shared best practices of sequence stratigraphic analysis of exploration and development projects worldwide.

Houston, Texas

Individual technical contributor with primary role of basin analysis and prospect generation and in West Africa (Gabon, Angola), North Sea (Norway), Vietnam, West Australia, New Zealand and Argentina.• Responsible for structural and isopach mapping, cross-sections, sequence stratigraphic interpretation of 2D and3D seismic data, fieldwork, core descriptions, regional studies and well-site operations• Provided technical leadership on West Africa Regional Project (WARP) – subsurface regional new ventures team assigned to risk assess and rank all of the basins in offshore West Africa from Niger Delta to Kwanza Basin – led to overall technical support for Amoco’s entry into Block 18 Offshore Angola • Provided technical support for bid rounds in Gabon (Shell), Norway (NorskHydro), Australia and New Zealand (Shell)

Houston, Texas

Individual technical contributor with primary role of basin analysis, prospect generation and field development assessment in the following US basins: Permian (Midland and Delaware), Midcontinent (Cambrian Reelfoot Rift) and onshore Gulf Coast (Vicksburg and Yegua trends in South Texas)• Responsible for structural and isopach mapping, cross-sections, sequence stratigraphic interpretation of 2-D and3-D seismic data, fieldwork, core descriptions, regional studies and well-site operations• Contributed as the Sed-strat technical lead on the Reelfoot Rift Project to assess the Cambro-Ordovician potential on 2.2 MM acres of leases in Missouri, Arkansas, Kentucky, Illinois and Tennessee. Regional exploration project work led to the drilling of two deep stratigraphic tests that confirmed pre-drill estimates of reservoir potential in the platform carbonates but lacked any evidence of a working petroleum system in the basin. • Conducted field studies on Amoco’s Siluro-Devonian and Permo-Penn oil fields in the Midland and Delaware Basins in West Texas and Eastern New Mexico focusing on updating reservoir characterizations, infill opportunities and wellwork nominations for recompletions.• Provided operational support for Amoco drilling activity by processing farm-out requests as well as performing wellsite geology operations support for company operated drilling activity.
