Reserves and Resources

Ryder Scott is one of the largest, oldest, and most respected reservoir evaluation consulting firms in the petroleum industry. Combining capable judgment with the latest technology, Ryder Scott has earned worldwide recognition for our reliable predictions of the performance of complex oil and gas reservoirs and a worldwide reputation for quality, independent reporting.

A Reserves evaluation is the process of forecasting estimated petroleum volumes, often called future production profiles, anticipated to be commercially, economically, and technically recoverable from producing and planned wells in known oil and gas accumulations. The consultant classifies oil and gas reserves as proved, probable, and possible. Proved has the highest certainty level that an estimate of ultimate recovery will be reached or exceeded. Probable and possible have relatively lower confidence levels, respectively.

At Ryder Scott, we adhere to country-specific regulatory requirements in Reserves Certification and Resource Estimation. As an Independent Qualified Reserves Evaluator (IQRE), we provide:

  • SEC Compliant Reporting
  • SPE-PRMS Compliant Reporting
  • NI 51-101 COGEH Compliant Reporting

We have a long-standing relationship with the Society of Petroleum Engineers (SPE) Oil and Gas Reserves Committee (OGRC) and support constant improvement in the Reporting of Reserves.
