What do we do?

Specialized in regulatory applications, reservoir and production engineering using tried and proven techniques, Proven Reserves brings a wealth of knowledge to each evaluation project.

Proven Reserves Exploitation Ltd. are experts in regulatory applications for oil and gas development. Our experienced team will guide your application from the initial conception stage to the final AER disposition, enabling the AER to process the application as quickly and efficiently as possible.

Also, Proven Reserves offers consulting work in reservoir engineering varying from data catalog to simulations. Our experienced staff uses the top of the line technologies and proven methodologies in our simulations.

Example:  Not long ago, Proven Reserves provided consulting work to a large oil and gas company. We used petro-physics software to investigate the homogeneity of a gas pool in a field. The end result was the discovery of other potential gas zones where Proven Reserves suggested additional perfs.  The client acted on our suggestions, which added 2 million dollars of additional reserve value.
