INTEGRATED SYNTHESIS OF PERMIAN BASIN DEPOSITIONAL HISTORY AND STRATIGRAPHIC ARCHITECTURE: DATA AND

1
INTEGRATED SYNTHESIS OF PERMIAN BASIN
DEPOSITIONAL HISTORY AND STRATIGRAPHIC
ARCHITECTURE DATA AND MODELS FOR RECOVERING
EXISTING AND UNDISCOVERED OIL RESOURCES
PBSS

• A PROPOSAL FOR A NEW INITIATIVE
• BY THE BUREAU OF ECONOMIC GEOLOGY

2
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

3
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

4
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

5
SOURCE DATA

• Reservoir studies
• Cores
• Wireline logs
• 3D 2D seismic
• Outcrop studies
• Published reports
• Company data

6
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.
