INTEGRATED SYNTHESIS OF PERMIAN BASIN DEPOSITIONAL HISTORY AND STRATIGRAPHIC ARCHITECTURE: DATA AND MODELS FOR RECOVERING EXISTING AND UNDISCOVERED OIL RESOURCES A PROPOSAL FOR A NEW INITIATIVE BY THE BUREAU OF ECONOMIC GEOLOGY PBSS

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

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

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

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

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.

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