Reserves Certification for Onshore Mexico

An onshore operator in Mexico needed independent reserves certification with expertise in assessing field reactivations, geologically complex environments and in shale resources plays.

Project Highlights

  • Evaluated 140MMbbl original oil in place
  • Stratigraphically complex fields
  • Project turnaround in under 15 business days
  • Support Canadian and Mexican regulatory requirements


  • A leading onshore operator in Mexico need independent reserves certification services within a very short timeline
  • The client needed a consulting firm with expertise in assessing field reactivations, geologically complex environments, and in shale resource plays, for future consideration
  • The mature fields, located in Southern Mexico’s Tabasco region, are geologically complex


  • Sproule evaluated the reactivated fields, validating future potential within a range of uncertainty
  • Final deliverables supported TSX (National Instrument 51-101) disclosure


  • Sproule completed the project in less than 15 days
  • Independent evaluation contributes to investor confidence and as required, evaluations will meet the regulatory requirements of both the Canadian (TSX) and Mexican (CNH) regulatory bodies
  • The client now has a clear understanding of the reserve process and how to navigate the Canadian regulatory system with confidence
  • The reserves evaluation provided assurance for the client’s directors, partners, and creditors and will support the development of opportunities in a key resource-rich region
