Geology & Oilfields

Knowledge today for generations tomorrow.

Wyoming petroleum value begins in the rocks, but a mapped reservoir is not proof of title, a producing lease or recoverable reserves. This section connects geology with actual land and production records.

From Rock to Revenue

  • Identify the formation and source/reservoir system.
  • Confirm land title, legal description and lease status.
  • Match the as-drilled well to the appropriate spacing or unit instruments.
  • Compare production with actual sales, pricing, deductions and payor decimals.
  • Separate historical recovery, approved plans and speculative future development.
