Disciplines and Capabilities

Our staff are intimately familiar with the recognized industry reserve and resource 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.
