Big Oil Fields Database

The Big Oil Fields Database contains over 6,422 oil reservoirs that account for over 75% of the oil expected to be ultimately produced in the United States by primary and secondary recovery processes.

In addition, the database has the following features:

  • Volumetrically consistent information on the original oil in-place endowment in each oil reservoir.
  • Updated information on cumulative oil production plus remaining oil reserves for each oil reservoir, providing rigorous data on remaining (“stranded”) oil that is the target for CO2 and other enhanced oil recovery (EOR) methods.
  • Reservoir-specific data on key reservoir properties that significantly influence the performance of a CO2-EOR project, including: swept-zone oil saturation, oil viscosity, reservoir heterogeneity (Dykstra-Parson’s Coefficient), oil gravity, reservoir temperature and reservoir pressure.
  • Reservoir-specific data on the existing field infrastructure and activities that influence the development costs and economic performance of a CO2-EOR project, including: active and shut-in producing wells, active and shut-in injection wells, and volumes of water injection and production.
  • Reservoir-specific data on any CO2-EOR activity already underway, including cumulative EOR production, the latest EOR production rate, and estimated remaining EOR reserves.

In addition, the Big Oil Fields Database contains a series of programmed sub-routines that provide output displays as well as other useful calculations for analytical purposes.

Output Displays

The Big Oil Fields Database is organized by Basin/Region and State and then by oil field within each state. Each oil field/reservoir contains 34 data items for each unique oil field in the database, including:

  • Location information
  • Key reservoir oil properties
  • Key reservoir formation characteristics
  • Active and shut-in oil production and water injection wells
  • Latest oil production, cumulative oil production and remaining proved oil reserves
  • Volume of original oil in-place
