A Closer Look at the Woodford
Arkoma Basin WOODFORD HUNTON SYLVAN Logs leased from TGS 150-200 thick Fairly uniform porosity Hot gamma throughout Variable but predictable and high resistivity Underlain by Hunton and Sylvan Dominated by dry gas production
WOODFORD HUNTON Anadarko Basin Logs leased from TGS 200-250 thick Hot gamma throughout Higher and more variable porosity Lower and more uniform resistivity Underlain by Hunton and Sylvan Bounded by pressure Significant liquids-rich zone

2014: High Fluid Volume
Double Plays: Filling the Value Gap Piggyback conventional drilling on horizontal development in lease fairways HBP with profitable foundation production from vertical development Long term reserve growth from horizontal development
Oklahoma s Oil and Gas Landscape Horizontal drilling moves the needle and creates an opportunity in the vertical value gap High fluid volume plays elevate the importance of artificial lifting and surface operations Heterogeneous reservoirs require a renewed focus on trap configuration and geologic insight
