The ERCB’s current enforcement actions regarding ER schemes are set out in Directive 019: Compliance Assurance. 2.2 Enhanced Oil Recovery Project [Rescinded] 2.3 Enhanced Recovery Recognition and Good Production Practice for Enhanced and Oil Recovery Schemes [Rescinded] 2-22 • ERCB Directive 065: Resources Applications / Enhanced Recovery Scheme (October 2011)
2.4 Application for Concurrent Production 2.4.1 Background Concurrent production (CCP) is defined as the production of an oil accumulation and its associated gas cap at the same time. Section 39(1)(e) of the Oil and Gas Conservation Act requires that no CCP scheme may proceed unless approved by the ERCB. CCP is a poolwide depletion decision requiring equitable treatment of all participants with productive wells. 2.4.2 When to Make This Application If there is a need or desire to produce gas-cap gas either directly via a gas well or indirectly through oil zone perforations, application must be made to the ERCB. CCP approval can take the form of one or more of the following: • outright CCP that allows for production of gas-cap gas from both oil and gas wells • CCP where gas may be produced through the oil zone perforations only • CCP with a maximum gas withdrawal rate • CCP with a maximum gas-oil ratio (GOR) above which the wells must be shut in • CCP where only certain wells may be produced • CCP for specific areas of a pool 2.4.3 Terms of Approval A CCP application would likely be approved if the ERCB is satisfied that 1) gas-cap gas production would have a negligible impact on the ultimate oil recovery from the pool or that gas-cap gas production is unavoidable if oil is to be recovered from a given pool; 2) all gas production is or will be conserved; and 3) all potentially adversely affected parties in the pool agree with the proposed CCP scheme. 2.4.4 Requirements for an Application for Concurrent Production Conservation Requirements Comments 1) Your geological interpretation of the pool involved, including a) oil and gas net pay isopach maps of the pool, b) where pool delineation or fluid interface locations are based on structural interpretation, a structure contour map of the pool and offsetting area, c) an interpreted and annotated log crosssection or representative well log(s) showing the ERCB Directive 065: Resources Applications / Concurrent Production (October 2011) • 2-23
