Glossary of Terms Used in Petroleum Reserves/Resources (неопр.) (PDF). Society of Petroleum Engineers (2005). — «Proved reserves are those quantities of petroleum which, by analysis of
geological and engineering data, can be estimated with reasonable certainty to
be commercially recoverable, from a given date forward, from known reservoirs
and under current economic conditions, operating methods, and government
regulations... . If probabilistic methods are used, there should be at least a 90%
probability that the quantities actually recovered will equal or exceed the
estimate. Often referred to as P1, sometimes referred to as “proven”.» Дата обращения: 20 апреля 2008. Архивировано 28 марта 2012 года.
