Disciplines & Capabilities

Globe Icon Separator Red

Our technical staff is intimately familiar with the recognized industry reserves and resources definitions, specifically those set forth by (1) U.S. Securities and Exchange Commission Regulation S-X Rule 4-10(a), (2) the 2007 Petroleum Resources Management System approved by the Society of Petroleum Engineers, and (3) the Society of Petroleum Evaluation Engineers (Calgary Chapter) and Canadian Institute of Mining, Metallurgy & Petroleum (Petroleum Society). We employ deterministic methods to estimate reserves for most evaluations and also utilize stochastic methods to determine probabilistic estimates of reserves for many exploration studies, early field development projects, and large field developments.
