Section 165:10-15-1 - Classification of oil pools and projects

(1) Discovery oil pool (165:10-15-5 ).

(2) Allocated oil pool (165:10-15-9 ).

(3) Unallocated oil pool (165:10-15-12 ).

(4) Enhanced oil recovery project (165:10-15-14 ).

(5) Excessive water exempt oil project (165:10-15-16 ).

(6) Reservoir dewatering oil spacing unit (165:10-15-18 ).

(1) Pool rules controlled by volumetric withdrawal.

(2) Discovery oil pool rules.

(3) Allocated oil pool rules.

(4) Some other order of the Commission.

(1) A new oil pool which has complied with the provision of 165:10-15-5 may be granted discovery allowable production rates, administratively, subject to either:

(2) Each permitted discovery oil well shall be subject to discovery oil pool rules until either:

(1) The Commission shall classify an oil pool as an allocated oil pool when:

(2) A gas well located in an allocated oil pool that is reclassified as an oil well for allowable purposes shall be subject to allocated oil pool rules.

(3) Each allocated oil well shall be subject to the allocated oil pool rules until the Commission reclassifies the well or pool.

(1) Classification of unallocated oil pool:

(2) Each unallocated oil well shall be subject to unallocated oil pool rules until the Commission reclassifies the well or pool.

(1) Authorized pressure maintenance. The Commission may, upon application, notice, and hearing, authorize the pressure maintenance of a pool or the production of oil by the injection of fluid, fluids, gas, gases, or other material into a common source of supply or a portion thereof, whether unitized or not, where substantial quantities of additional oil may be recovered which could not be recovered under ordinary primary depletion methods. When so authorized, the project will be classified as an Enhanced Oil Recovery Project with one of the following classifications:

(2) Status of a gas well reclassified as an oil well. If a well classified as a gas well in an enhanced oil recovery project is reclassified as an oil well for allowable purposes, the well shall be subject to the appropriate enhanced oil recovery project rules.

(3) Termination of enhanced oil recovery status. Each enhanced oil recovery well shall be subject to enhanced oil recovery project rules until one of the following occurs:

(1) Oil production rates. The Director of Conservation may administratively authorize the production of oil at rates greater than the normal allowable provided the water-oil ratio of the well and/or pool is greater than or equal to 3:1. All applications shall comply with 165:5-7-12.

(2) Status of a gas well reclassified as an oil well. If a well classified as a gas well in an excessive water exempt oil project is reclassified as an oil well for allowable purposes, the well shall be subject to excessive water exempt oil project rules.

(3) Termination of excessive water exempt status. Each excessive water exempt well shall be subject to excessive water exempt oil project rules until at least one of the following occurs:

(1) Oil production rates. To set an allowable for a well in a reservoir dewatering oil spacing unit, the operator shall refer to Appendix J and submit the appropriate forms and/or application as provided in OAC 165:10-15-18.

(2) Reclassification of oil well as gas well. If a well in a reservoir dewatering oil spacing unit is later subject to reclassification as a gas well for allowable purposes, such reclassification will be determined according to general classification procedures based on its gas/oil ratio pursuant to OAC 165:10-1-6(d) and (e) and 165:10-13-2. If the subject well is designated an excessive water exempt oil project pursuant to OAC 165:10-15-1(g) and 165:10-15-16, reclassification shall be determined by OAC 165:10-15-1(g)(2). If the subject well is assigned an allowable based upon its most efficient rate pursuant to OAC 165:10-13-5, such allowable shall remain in effect under the order establishing the production rate, so that the well will not be reclassified, until its status is modified or terminated by the terms of the instant or a subsequent Commission order.

(3) Termination of reservoir dewatering oil spacing unit allowable. The oil allowable assigned a reservoir dewatering oil spacing unit shall remain in effect until one of the following occurs:
