  2. Location Exception Rules: Oklahoma Corporation Commission

  3. 165:5-7-9Well Location Exception • (a) Notice of hearing for an order authorizing a well to be drilled for oil or gas into any common source of supply at a requested location therein other than that prescribed by a rule or order of the Commission shall be served by the applicant no less than fifteen (15) days prior to the date of the hearing, by regular mail upon the operator of each well located in an adjoining or cornering tract of land or drilling and spacing unit, currently producing from the same

  4. common source of supply, toward which the well location is proposed to be moved and the same notice also shall be required if the requested well location would be closer to the wells producing from those adjoining or cornering tracts of land or drilling and spacing units than would be permitted at a legal location. Provided, however, if the applicant, or any entity to be named operator of the requested well location, is the operator of any of the wells in an adjoining or cornering tract of land or drilling and spacing unit, identified herein above, then the applicant shall serve each working interest owner in such well by regular mail. All applications and notices

  5. for location exception shall specify the surface location of the well. • (b) For a directionally drilled well, the application and notice shall also include the proposed location of the well's entry into and the proposed location of the well's exit from the common source of supply for which the location exception is requested, expressed in feet from the two nearest boundaries of the drilling and spacing unit, or, if no drilling and spacing unit has been established, from the two nearest boundaries of the mineral estate(s) upon which the well will be drilled. Provided that, at the time of hearing, the well's surface location may be changed

  6. and the location of the well's entry into the common source of supply and/or the location of the well's exit from the common source of supply, as set out in the notice of hearing, may be changed to another subsurface location which is not closer to the offsetting well or to the drilling and spacing unit boundaries or the tract boundaries described in the notice of hearing. • (c) For a horizontal well, the application and notice shall also include the proposed location of the completion interval, as defined by OAC 165:10-3-28, within the common source of supply for which the location exception is requested, expressed as the

  7. distance in feet of each end point of the completion interval from the two (2) nearest boundaries of the drilling and spacing unit, or, if no drilling and spacing unit has been established, from the two (2) nearest boundaries of the mineral estate(s) upon which the well will be drilled. In addition, a tolerance distance shall be expressed in terms of feet from the proposed completion interval. If the applicant does not intend to drill between the two end points of the completion interval on a straight line in the horizontal plane, the application shall contain a pre-plat depicting the proposed location of the entire completion interval within the unit or tract.

  8. (d) If a directionally drilled or horizontal well is drilled and completed in compliance with an interim order approving a location exception, and no party of record has requested a hearing, the Commission may issue a final order approving the location exception, without further hearing, based on an administrative review by the Commission’s Technical Services Department of the following documents, which must be filed with the Court Clerk for the record: the directional survey, a final plat showing the actual location of the lateral, and the well completion report. The applicant must also submit a proposed final order to the Commission’s Technical Services

  9. Department regarding causes remanded for administrative review. In the event the directional survey shows that a directionally drilled or horizontal well was not drilled and completed in compliance with the interim location exception order, the applicant shall notify the Commission and all of the parties entitled to notice in the original hearing establishing the interim order by filing an amended application in the cause setting forth the actual subsurface locations of the well and by giving proper notice thereof. The actual subsurface locations of the well will be considered at a hearing conducted on the date specified in the interim location exception

  10. order, or on such date to which the hearing is continued. • (e) Notice of hearing for an order authorizing a well to be drilled for oil or gas at a location other than that prescribed by a rule or order of the Commission shall be published pursuant to 165:5-7-1(n)(2).

  11. 165:10-1-21General Well Spacing Requirements Any well drilled for oil or gas to an unspaced common source of supply 2,500 feet or more in depth shall be located not less than 330 feet from any property line or lease line, and shall be located not less than 600 feet from any other producible or drilling oil or gas well when drilling to the same common source of supply; provided and except that in drilling to an unspaced common source of supply that is less than 2,500 feet in depth, the well shall be located not less than 165 feet from any property line or lease line and not less than

  12. 300 feet from any other producible or drilling oil or gas well in the same common source of supply; provided, however, that the completed depth of the discovery well shall be recognized as the depth of the common source of supply for the purpose of this Section; provided further, when an exception to this Section is granted, the Commission may adjust the allowable or take such other action as it deems necessary for the prevention of waste and protection of correlative rights.

  13. 165:10-1-24Permitted Well Locations within Standard Drilling and Spacing Units

  14. (a) The permitted well location within any standard square drilling and spacing unit shall be the center of the unit. The permitted well locations within standard rectangular drilling and spacing units shall be the centers of alternate square tracts constituting the units (alternate halves of the units); provided, however, a well will be deemed drilled at the permitted location if drilled within the following tolerance areas:

  15. (1) Not less than 165 feet from the boundary of any standard 10-acre drilling and spacing unit or the proper square 10-acre tract within any standard 20-acre drilling and spacing unit. • (2) Not less than 330 feet from the boundary of any standard 40-acre drilling and spacing unit or the proper square 40-acre tract within any standard 80-acre drilling and spacing unit.

  16. (3) Not less than 660-feet from the boundary of any standard 160-acre drilling and spacing unit or the proper square 160-acre tract within any standard 320-acre drilling and spacing unit. • (4) Not less than 1320 feet from the boundary of any standard 640-acre drilling and spacing unit.

  17. (b) The proper square tract of a rectangular drilling and spacing unit established prior to January 1, 1971, for which a slot drilling pattern was prescribed, shall be the northeast quarter and the southwest quarter of the governmental section, quarter section, or quarter quarter section containing two abutting rectangular drilling and spacing units; provided, slot patterns may be established or re-established upon application, notice, and hearing where consistent with available geological and engineering information when necessary to prevent waste or protect correlative rights.

  18. (c) The permitted well location tolerance areas set out in (a) of this Section shall apply to each standard drilling and spacing unit heretofore or hereafter established, notwithstanding the provisions of any special order of the Commission prescribing a different permitted well location tolerance area; provided, however, this Section shall not affect any adjusted allowable or penalty applied to any well by special order of the Commission prior to the effective date of this Section, nor shall any well heretofore drilled within a then permitted tolerance area be deemed outside the permitted tolerance area by reason of this Section.

  19. (d) Wells drilled offpattern without first obtaining an exception after notice and hearing by the Commission are hereby prohibited from producing either oil or gas. • (e) Whenever permission is granted to drill a well at a location other than specified in this Chapter, the allowable or production therefrom, or both, may be adjusted for the protection of the correlative rights of all persons entitled to share in the common source of supply.

  20. (f) Unless the order granting a well location exception provides otherwise, the permission to drill the well at the excepted location shall expire twelve (12) months after the date of the order, unless a well was commenced at the excepted location on or before the expiration date. The order granting the well location exception will thereafter expire when the well is plugged, abandoned, or converted. • (g) An application for an emergency order granting a well location exception may be granted if the applicant has obtained the written consent of the operator of each adjoining or cornering tract of land or drilling and spacing unit, currently producing

  21. from the same formation, toward which the well location is proposed to be moved. Provided, however, if the applicant is the operator of the well in an adjoining or cornering tract of land or drilling and spacing unit, currently producing from the same formation, toward which the well location is proposed to be moved, the applicant shall obtain the written consent of each working interest owner in such well. (1) Letters evidencing the written consent of off-set operators and working interest parties as described in this subsection shall be introduced and received into evidence at the time of the

  22. emergency hearing and reviewed. Copies of said letters shall be filed with the Court Clerk of the Commission. (2) If the written consent described in this subsection cannot be obtained, the applicant may send written notice to said non-consenting party giving that party at least five days notice of the emergency hearing. If said nonconsenting party fails to appear, then the emergency application shall be considered and may be granted without the non-consenting party's written consent. The applicant shall file an affidavit of mailing with the Court Clerk to prove the mailing of the five day notice.

  23. (h) If a spacing application is currently pending and the applicant or any party who owns the right to drill needs to commence a well prior to issuance of the spacing order, the applicant or party shall obtain an emergency order to commence such well and an emergency location exception order if: (1) The proposed well is offpattern according to the existing spacing for any formation involved, or (2) The well is offpattern according to 165:1O-1-21 governing well patterns for unspaced areas.

  24. (i) Whenever an order permits an offpattern well, the order permitting said well may provide, at the request of a party of record in the cause, for said party to have the right, at his sole cost and risk, to attend and monitor the initial potential testing and all subsequent annual testing of the proposed offpattern well. If the order permits witnessing of tests as prescribed above, then the order shall further provide that at least five days prior to the initial potential testing and each subsequent annual testing of the proposed well, the operator of the well shall notify, in writing, all parties of record in the

  25. cause who requested to attend and monitor these tests of the date and time upon which said testing shall commence.

  26. 165:10-3-27Deviation from the vertical • (a) Well location for purposes of well spacing. For purposes of the well spacing requirements of 165:1O-1-21 and 165:1O-1-24, the location of a well in a common source of supply is the closest point to the unit boundary where the wellbore intersects the common source of supply.

  27. (b) Presumed bottom hole location. For purposes of review of Form 1000 applications, the Conservation Division may presume that the location in a common source of supply of a well without a horizontal drainhole is the same as the surface location for the well unless: (1) The operator submits a bottom hole survey, if the well has been drilled; or (2) The operator complies with (c) (1) of this Section.

  28. (c) Permitted and prohibited Locations. (1) Offpattern surface location; permitted subsurface location. • The Conservation Division may approve a Form 1000 for a well to be commenced without a location exception at an offpattern surface location for a common source of supply when: (i) The Form 1000 lists a subsurface location which is a permitted location for the common source of supply.

  29. (ii) Issuance of a Permit to Drill is conditioned on the operator running a bottom hole survey within 30 days after reaching total depth and on the operator submitting the survey to the Conservation Division within 45 days after the well reaches total depth. (B) The well shall not receive an allowable for the common source of supply until a bottom hole survey shows that the well is at a permitted location or until the operator obtains a location exception order for the subsurface location.

  30. (2) Offpattern subsurface location. (A) The Conservation Division shall not approve a Form 1000 without a location exception order for an offpattern subsurface location. (B) Issuance of a Permit to Drill under (1) of this subsection does not permit an operator to have, without a location exception order, an offpattern subsurface location for a common source of supply.

  31. (d) Required directional and bottom hole surveys. For good cause, the Commission may order an operator to run directional and/or bottom-hole surveys for a common source of supply in a well: (1) Upon application, notice, and hearing; or (2) In any case involving the location of a well, upon motion of an affected party or upon the Commission's own motion.

  32. 165:5-15-4 Location exception orders for increased density wells • (a) Required language; allowable restrictions. A location exception order for an increased density well where allowable restrictions have been imposed shall contain language obligating the applicant to: (1) Maintain a monthly allocation schedule for the well which schedule shall show the method used in calculating the allowable, production and the status as to overage or underage.

  33. (2) Furnish a copy of the schedule to each offsetting operator who entered an appearance in the cause. (3) File with the Gas Department of the Oil and Gas Conservation Division, no later than February 15 each year, a summary of the schedule showing the allowable and production for the calendar year and the status as to overage and underage as of December 31.

  34. (b) Termination of order. A location exception order for an increased density well shall terminate if the relief granted is not undertaken within one (1) year from the order's date of issuance, unless otherwise provided in the order.

  35. 165:5-15-6Location Exception Orders • A location exception order shall terminate if the relief granted is not undertaken within one (1) year from the order's date of issuance, unless otherwise provided in the order. For directionally drilled wells, the location of the entry into and exit from the common source of supply must be specified.

  39. Increased Density Rules: Oklahoma Corporation Commission

  40. 165:5-7-10Increased Density • (a) Notice of hearing. (1) For increased well density applications, notice of hearing shall be served by the applicant no less than fifteen (15) days prior to the date of the hearing by regular mail upon: (A) Each person or governmental entity entitled to oil or gas or the proceeds of oil or gas produced from the common source of supply in the drilling and spacing unit

  41. for which the application for an increased density well has been filed; and (B) The operator, as shown by the records of the Commission, of each well which is commencing or currently producing from the same common source of supply in the drilling and spacing unit or any separate tract of land for which no drilling and spacing unit has been formed for such common source of supply adjoining, cornering or adjacent to the drilling and spacing unit for such an increased density well.
