1. NEW REGIONAL RESERVOIR PLAY CHARACTERIZATION PROGRAMS IN TEXAS & NEW MEXICO at the Bureau of Economic Geology Principal Investigators: Stephen C. Ruppel & Robert G. Loucks GEOLOGICAL SYNTHESIS OF THE PALEOZOIC OF THE PERMIAN BASIN (PBGSP) CARBONIFEROUS GAS SHALE RESOURCES IN TEXAS (CGSR)

2. GEOGRAPHIC SCOPE Permian Basin study area Barnett shale study area

3. PROGRAM GOALS Produce a detailed, comprehensive history of Paleozoic depositional and reservoir systems in the Permian Basin Create spatially integrated data bases of depositional, stratigraphic, lithologic, and petrophysical properties

4. TARGET RESOURCES Development Target: : 23 billion barrels of mobile oil remaining in existing reservoirs Exploration Target: 3.5 billion barrels of undiscovered oil and NGL resources

5. VALUE Provide fundamental stratigraphic and reservoir- specific data in a readily accessible and useable format. Integrated data will decrease the risk and increase the efficiency of exploitation Integrated data will define new opportunities for drilling. Integrated data will form the basis for new engineering approaches and completion practices

6. SOURCE DATA Reservoir studies Cores Wireline logs 3D & 2D seismic Outcrop studies Published reports Company data NEW STUDIES

7. DELIVERABLES Text: Written synthesis of history, stratigraphy, facies, structural history, and reservoir development in Permian Basin. Data: ARC/INFO GIS-based regional structure maps, facies maps, cross sections, core descriptions and data, outcrop descriptions and sections, core data, reservoir data, production data, publications, etc for each play.

8. TEXT First-year report on depositional history and stratigraphy of the Cambrian-Permian Incremental play reports as completed.
