SPE Definitions for Proved, Probable, Possible Reserves and ProspectiveResources

Proved Reserves are those quantities of petroleum, which by analysis ofgeoscience and engineering data, can be estimated with reasonable certainty tobe commercially recoverable, from a given date forward, from known reservoirsand under defined economic conditions, operating methods, and governmentregulations.

Probable Reserves are those additional Reserves which analysis of geoscienceand engineering data indicate are less likely to be recovered than ProvedReserves but more certain to be recovered than Possible Reserves.

Possible Reserves are those additional reserves which analysis of geoscienceand engineering data indicate are less likely to be recoverable than ProbableReserves.

1P refers to Proved Reserves, 2P refers to Proved plus Probable Reserves and 3Prefers to Proved plus Probable plus Possible Reserves.

Prospective Resources are those quantities of petroleum estimated, as of agiven date, to be potentially recoverable from undiscovered accumulations byapplication of future development projects. Prospective Resources have both anassociated chance of discovery and a chance of development. ProspectiveResources are further subdivided in accordance with the level of certaintyassociated with recoverable estimates assuming their discovery and developmentand may be sub-classified based on project maturity. Contingent Resources are those quantities of hydrocarbons which are estimated,on a given date, to be potentially recoverable from known accumulations, butwhich are not currently considered to be commercially recoverable.

Undiscovered Oil-In-Place is that quantity of oil which is estimated, on agiven date, to be contained in accumulations yet to be discovered. Theestimated potentially recoverable portion of such accumulations is classifiedas Prospective Resources, as defined above.
