proved reserves POSC reserves type Proved reserves are reserves that can be estimated within reasonable certainty to be recoverable under current economic conditions. Current economic conditions include prices and costs prevailing at the time of the estimate. Proved reserves must have facilities to process and transport to market those reserves that are operational at the time of the estimate, or there is a commitment or reasonable expectation to install such facilities in the future.   POSC epicentre 2.2 current
behind pipe proved reserves POSC reserves type Behind pipe proved reserves are expected to be recovered from zones behind casing in existing wells, which require additional completion work or a future completion prior to the start of production. proved reserves POSC epicentre 2.2 current
developed proved reserves POSC reserves type Developed proved reserves are expected to be recovered from existing wells and facilities (including behind pipe proved reserves). Improved recovery reserves are considered developed only after the necessary equipment has been installed, or when the costs to do so are relatively minor. proved reserves POSC epicentre 2.2 current
nonproducing proved reserves POSC reserves type Nonproducing proved reserves are reserves that are capable of being recovered but are not producing at the time of the estimate due to mechanical reasons, and the time of recovery is uncertain. proved reserves POSC epicentre 2.2 current
producing proved reserves POSC reserves type Producing proved reserves are reserves to be recovered from well completions open and producing at the time of the estimate. Improved recovery reserves are considered to be producing only after an improved recovery project is in operation. proved reserves POSC epicentre 2.2 current
shut in proved reserves POSC reserves type Shut in proved reserves are reserves that are expected to be recovered from well completions open at the time of the estimate, but which had not started producing, or were shut in due to market conditions or pipeline connection, or were not capable of production for mechanical reasons, and the time when sales will start is uncertain. proved reserves POSC epicentre 2.2 current
undeveloped proved reserves POSC reserves type Undeveloped proved reserves are reserves that are expected to be recovered: (1) from new wells on undrilled acreage, (2) from deepening wells into a different reservoir, or (3) where a relatively large expenditure is required to (a) recomplete an existing well or (b) install production or transportation facilities for primary or improved recovery projects. proved reserves POSC epicentre 2.2 current
unproved reserves POSC reserves type Unproved reserves are based on geologic and/or engineering data similar to that used in estimates of proved reserves; but technical, economic, or regulatory uncertainties preclude such reserves being classified as proved. Unproved reserves may be esitmated assuming future economic conditions different from those prevailing at the time of the estimate.   POSC epicentre 2.2 current
probable reserves POSC reserves type Probable reserves are less certain than proved reserves and can be estimated with a degree of certainty sufficient to indicate they are more likely to be recovered than not. unproved reserves POSC epicentre 2.2 current
possible reserves POSC reserves type Possible reserves are less certain than probable reserves and can be estimated with a low degree of certainty, insufficient to indicate wheter they are more likely to be recovered than not. unproved reserves POSC epicentre 2.2 current
