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.
PLAY DATA
• Regional structure and facies maps
• Regional cross sections
• Core descriptions and data
• Core photographs
• Reservoir cross sections
• Reservoir models
