Gas-in-place resource estimates make no allowance for recovery of the gas. The volumes of gas which may be recoverable will depend on the reservoir characteristics encountered and future economic conditions. These gas in place estimates are not compliant with volumes of oil and gas resources classified as "discovered petroleum initially-in-place" within the meaning of the Canadian Oil & Gas Evaluation Handbook (COGE Handbook). The term "discovered petroleum initially-in-place" is equivalent to discovered resources, and is defined in the COGE Handbook to mean that quantity of petroleum that is estimated, as of a given date, to be contained in known accumulations prior to production.
