Contingent Resources
Contingent Resources are those quantities of petroleum which are estimated, on a given date, to be potentially recoverable from known accumulations, but which are not currently considered to be commercially recoverable. It is recognized that some ambiguity may exist between the definitions of contingent resources and unproved reserves. This is a reflection of variations in current industry practice. It is recommended that if the degree of commitment is not such that the accumulation is expected to be developed and placed on production within a reasonable timeframe, the estimated recoverable volumes for the accumulation be classified as contingent resources. Contingent Resources may include, for example, accumulations for which there is currently no viable market, or where commercial recovery is dependent on the development of new technology, or where evaluation of the accumulation is still at an early stage.

Discovered-Petroleum-Initially-In-Place (DPIIP)
Discovered Petroleum-Initially-In-Place (DPIIP) is that quantity of petroleum which is estimated, on a given date, to be contained in known accumulations, plus those quantities already produced therefrom. DPIIP may be subdivided into Commercial and Sub-commercial categories, with the estimated potentially recoverable portion being classified as Reserves and Contingent Resources respectively, as defined elsewhere in this Glossary.

Gross or gross
Relating to production / reserves: Crew’s working interest (operating and non-operating) share before deduction of royalties and without including any royalty interestRelating to wells: the total number of wells in which Crew has an interestRelating to properties: the total area of properties in which the Corporation has an interest

Net or net
Relating to production / reserves: Crew’s working interest (operating and non-operating) share after deduction of royalty obligations, plus Crew’s royalty interests in production or reservesRelating to wells: the number of wells obtained by aggregating Crew’s working interest in each of its gross wellsRelating to properties: the total area in which Crew has an interest multiplied by the working interest owned by Crew

NI 51-101
National Instrument 51-101 Standards of Disclosure for Oil and Gas Activities.

Operating Netback
A measure of oil and gas sales net of royalties, production and transportation expenses. This is a non-GAAP measure used specifically in the oil and gas industry as a benchmark to compare performance between different areas of operations and different peer companies.

Prospective Resource
Prospective Resources are those quantities of petroleum which are estimated, on a given date, to be potentially recoverable from undiscovered accumulations.

Total-Petroleum-Initially-In-Place (TPIIP)
Total Petroleum-initially-in-place (TPIIP) is that quantity of petroleum which is estimated to exist originally in naturally occurring accumulations. TPIIP is that quantity of petroleum which is estimated, on a given date, to be contained in known accumulations, plus quantities already produced therefrom, plus estimated quantities in accumulations yet to be discovered. TPIIP may be subdivided into Discovered Petroleum-initially-in place and Undiscovered Petroleum-initially-in-place, with Discovered Petroleum-initially-in-place being limited to known accumulations. It is recognized that all Petroleum-initially-in-place quantities may constitute potentially recoverable resources since the estimation of the proportion which may be recoverable can be subject to significant uncertainty and will change with variations in commercial circumstances, technological developments and data availability. A portion of those quantities classified as Unrecoverable may become recoverable resources in the future as commercial circumstances change, technological developments occur, or additional data are acquired.

Undiscovered Petroleum-Initially-In-Place (UPIIP)
Undiscovered Petroleum-initially-in-place (UPIIP) is that quantity of petroleum which is estimated, on a given date, to be contained in accumulations yet to be discovered. The estimated potentially recoverable portion of UPIIP is classified as Prospective Resources, as defined elsewhere in this Glossary.
