Decision commented on: Proceeding 336 Application 1820596 Pool Delineation, Crossfield Basal Quartz C & V Pools, June 2, 2016, 2016 ABER 007
Alberta’s Oil and Gas Conservation Act, RSA 2000, c O-6 (OGCA) defines a pool as “(i) a natural underground reservoir containing or appearing to contain an accumulation of oil or gas, or both, separated or appearing to be separated from any other such accumulation”. Wells are identified as producing from particular pools and many provisions of the OGCA and the Oil and Gas Conservation Rules, Alta Reg 151/1971 (OGCR) turn on the question of whether or not a particular well is producing from a particular pool. For example, s 15(3) of the OGCA provides that “No person shall apply for a licence for a well for the purpose of obtaining production from the same pool as that from which another well is obtaining or capable of obtaining production in the same drilling spacing unit …”.
In this particular case, the applicant, Bearspaw Petroleum Ltd wanted its well classified as producing from the Crossfield Basal Quartz C Pool (BQ C Pool) rather than the single well BQ V pool in order to be able to gain access to the gas processing plant operated by the C Pool working interest owners – if necessary by means of a common processor order under s 53 of the OGCA. Since it is usually necessary to establish drainage as a pre-condition to obtaining a common processor order (i.e. that H’s well or wells are draining production from underneath B’s leased lands) (see Directive 065, Resources Applications for Oil and Gas Reservoirs, Unit 1, Equity) B first had to establish that its well was in the same pool as H’s wells.
