2D or 2D Seismic

Seismic data which is acquired along a line with a ‘Shot and Receiver’ configuration that allows the signal-to- noise ratio to be enhanced by linear stacking of the reflections caused by subsurface interfaces between rocks with different acoustic properties

3D or 3D Seismic

Seismic data which is acquired in a multi-azimuthal pattern and processed such that the signal-to-noise ratio is enhanced by three dimensional stacking of the reflections caused by subsurface interfaces between rocks with different acoustic properties

Contingent Resources/CR

Those quantities of petroleum estimated, as of a given date, to be potentially recoverable from known accumulations by application of development projects but which are not currently considered to be commercially recoverable due to one or more contingencies. Contingent Resources are a class of discovered Recoverable Resources.

Prospective Resources/PR

Those quantities of petroleum estimated, as of a given date, to be potentially recoverable from undiscovered accumulations by application of future development projects. Prospective Resources have both an associated chance of recovery and a chance of development. Prospective Resources are further subdivided in accordance with the level of certainty associated with the recoverable estimates assuming their discovery and development and may be sub-classified based on project maturity

Proved Developed Reserves

Proved Reserves that can be produced with existing wells and perforations, or from additional reservoirs where minimal additional capital investment is required

Proved Undeveloped Reserves

Proved Reserves that require additional capital investment to bring the oil or gas to the surface

Proved Reserves (‘Proved’)

Those quantities of petroleum, which by analysis and geoscience and engineering data, can be estimated with reasonable certainty to be commercially recoverable. It is likely that the actual remaining quantities recovered will exceed the estimated Proved Reserves

Probable Reserves (‘Probable’)

Those additional reserves, which by analysis and geoscience and engineering data, are less likely to be recovered than Proved Reserves but more certain to be recovered than Possible Reserves. It is equally likely that actual remaining quantities recovered will be greater than or less than the sum of the estimated Proved plus Probable Reserves

Possible Reserves (‘Possible’)

Those additional reserves which analysis and geoscience and engineering data suggest are less likely to be recovered than Probable Reserves. The total quantities ultimately recovered from the project have a low probability to exceed the sum of Proved plus Probable plus Possible Reserves
