                         REPORT OF THE COMMISSION

 

             This cause came on for hearing before the Commission on July 20, 1992, in Room 101, State Education Building, 201 East Colfax, Denver, Colorado, after giving Notice of Hearing, as required by law on the verified application of Snyder Oil Corporation, for an order to amend Cause No. 499 to establish 320-acre drilling and spacing units for production from the Dakota Formation, to amend Cause Nos. 499, 232, 407 and 493 to allow the wells to be recompleted to the "J" Sand, Codell, Niobrara, Sussex and Shannon Formations, and further, to allow the downhole commingling of production from the Dakota, "J" Sand, Codell, Niobrara and Sussex Formations.

 

                                FINDINGS

 

             The Commission finds as follows:

 

             1.  Snyder Oil Corporation as applicant herein, are interested parties in the subject matter of the above‑referenced hearing.

 

             2.  Due notice of the time, place and purpose of the hearing has been given in all respects as required by law.

 

             3.  The Commission has jurisdiction over the subject matter embraced in said Notice, and of the parties interested therein, and jurisdiction to promulgate the hereinafter prescribed order.

 

             4.  In Order No. 499-1, the Commission established 320-acre drilling and spacing units for the production of oil, gas and associated hydrocarbons from the Dakota Formation, identical to the 320-acre drilling and spacing units previously established for the "J" Sand Formation required by Cause No. 232, with the permitted well to be located in the NW1/4 and the SE1/4 of the section and no closer than 990 feet to the boundaries of the quarter section, for certain lands.  Subsequent Order No. 499-3 established 320-acre drilling and spacing units for additional lands, with the permitted well to be located in any quarter section and no closer than 990 feet to the boundaries of the quarter section for production from the Dakota Formation and allowing the dual completion and downhole commingling of production from the Dakota, "J" Sand, Codell, Niobrara, Sussex and Shannon Formations.

 

             5.  In Cause No. 232, the Commission established 320‑acre drilling and spacing units for the production of gas from the "J" Sand in the Wattenberg Field with one well allowed for each unit to be located in the NE1/4 and SW1/4 and no closer than 990 feet to the boundaries of the quarter section.  On August 21, 1979, the Commission issued Order No. 232‑20 which allowed a second well to be drilled on each 320‑acre unit.

 

             6.  In Order No. 407‑1, the Commission established 80‑acre drilling and spacing units for the production of oil and/or gas and associated hydrocarbons from the Codell Formation.  Wells shall be located in the center of the 40‑acre tract or quarter‑quarter section with a tolerance of 200 feet in any direction.  In Order Nos. 407‑10 and 407‑13, the Commission amended Order No. 407‑1 to include production from the Niobrara Formation in certain lands and to allow the downhole commingling of production from the Codell and Niobrara Formations.

 

             7.  In Order No. 493-2, the Commission established 80‑acre drilling and spacing units for the production of oil, gas and associated hydrocarbons from the Sussex Formation.  Wells shall be located in accordance with the permitted locations established in Cause No. 407 and shall allow the downhole commingling of production from the Codell, Niobrara and Sussex Formations.

 

             8.  That evidence presented at the hearing indicates that the Dakota, "J" Sand, Codell, Niobrara, Sussex and Shannon Formations constitute common sources of supply of oil, gas and associated hydrocarbons underlying the following described lands in Weld County, Colorado to‑wit:


 

                 Township 2 North, Range 68 West, 6th P.M.

                            Section 25:  W1/2

 

                 Township 3 North, Range 65 West, 6th P.M.

                             Section 9:  W1/2

 

             9.  Engineering testimony presented indicated that prudent production engineering practices would allow commingled production from the various reservoirs resulting in increased recovery of reserves and no irremediable reservoir damage.

 

             10.  That additional rules be established for the protection of correlative rights and procedures to process recompletion, commingled and dual completion requests.

 

                                  ORDER

 

             NOW, THEREFORE, IT IS ORDERED, that the following rules and regulations shall apply hereafter to a well or wells drilled, completed or recompleted in the Dakota Formation, where the production is commingled or dually completed with the "J" Sand, Codell, Niobrara, Sussex and Shannon Formations underlying the described herein below, in addition to other applicable rules and regulations and orders of the Commission, if any, heretofore adopted and not in conflict herein:

 

             Rule 1.  Three hundred and twenty (320) acre drilling and spacing units shall be and the same are hereby established for the production of oil, gas and associated hydrocarbons from the Dakota Formation underlying the following described lands in Adams and Weld Counties, Colorado, to-wit:

 

                 Township 2 North, Range 68 West, 6th P.M.

                            Section 25:  W1/2

 

                 Township 3 North, Range 65 West, 6th P.M.

                             Section 9:  W1/2

 

             Rule 2.  Said drilling units shall consist of the E1/2 and the W1/2 or the N1/2 and the S1/2 of each section, according to governmental survey, and said units shall be identical to the 320-acre drilling and spacing units previously established for the "J" Sand Formation required by Cause No. 232, with the permitted well to be located in any quarter section, no closer than 990 feet from the boundary of the quarter section.

 

             Rule 3.  That evidence presented at the hearing indicates that the Dakota, "J" Sand, Codell, Niobrara, Sussex and Shannon Formations constitute common sources of supply of oil, gas and associated hydrocarbons underlying the following described lands in Weld County, Colorado to‑wit:

 

 

                 Township 2 North, Range 68 West, 6th P.M.

                            Section 25:  W1/2

 

                 Township 3 North, Range 65 West, 6th P.M.

                             Section 9:  W1/2

 

             a.  The size of the voluntary unit for production from the Codell, Niobrara, Sussex and Shannon Formations is either (i) 160‑acres or (ii) the same size as the unit for production from the Dakota and "J" Sand Formations, with the unit for the Codell, Niobrara or Sussex Formations not less than that prescribed by Cause Nos. 407 and 493; and

 

             b.  The location of the wellbore in the Codell, Niobrara or Sussex Formations is not less than 920 horizontal feet from any existing wellbore in the Codell, Niobrara or Sussex Formations capable of producing from such Formation and, in addition, not less than 920 horizontal feet from any proposed, permitted well for which the Codell, Niobrara or Sussex Formations is the identified objective Formation.

 

             Rule 4:  If an applicant wishes to produce oil, gas or associated hydrocarbons from the Codell, Niobrara or Sussex Formations and the well is not located at a legal location under these rules or under Cause Nos. 407 and 493, the applicant shall file with the Commission waivers or consents signed by the owners toward whom the well is located, including but not limited to owners of interests in other Formations not participating in the proposed operation, agreeing that the well may be located where the applicant proposes to drill the well.  If written waivers or consents are not obtained from all of said owners, then the applicant shall give written notice of the proposed operation by certified mail to said owners.  If an owner of the well is also the owner of a lease toward which the well is located, then the applicant must also obtain a waiver or consent or give written notice by certified mail to the mineral interest owner subject to such lease.  The notice and any request for waiver or consent shall state that anyone who objects to the proposed operation should file a protest with the Commission within 30 days of the date of the notice.  The applicant shall provide the Director with a copy of the notice and a list of the addressees prior to approval of any exception location under this rule.  If the applicant intends to commingle production from the well for which an exception location is requested, then the applicant should file contemporaneously with the exception location application the application materials required in Rule 5 below.  If no written objections are filed within 30 days after notice is received, the Director is authorized to approve the proposed location as an exception location without a hearing.  If a written objection is filed, or upon motion of the applicant or the Director, the application shall be heard in accordance with the rules of the Commission.

 

             Rule 5:  Multiple zone completions and downhole commingling of oil, gas and associated hydrocarbons from the Dakota, "J" Sand, Codell, Niobrara, Sussex and Shannon Formations may be approved by the Director without hearing provided the well is located at a legal location for each Formation from which production is obtained; and further that the applicant files with the Commission prior to commencing operations, (1) a complete  Application for Permit to Drill, (2) a Sundry Notice setting forth the manner and method of completion proposed, including a diagrammatic sketch of the mechanical installation for multiple zone completion and commingling and (3) an exhibit showing the location of all wells on adjacent premises and all offset wells on adjacent lands.  Each application shall also designate the drilling and spacing units within 1/4 mile of the well proposed to be commingled and indicate that the owners have given written consent to the commingling.  If the well to be commingled is within a voluntary unit for production from the Codell, Niobrara, Sussex and Shannon Formations and is not less than 460 feet from the boundary of the unit and not less than 920 feet from any well not included in the voluntary unit, then the applicant shall not be required to give notice to owners outside the voluntary unit.  In the absence of common ownership, the application shall also include a statement that each person sharing in the costs and/or proceeds from such well has agreed to a method for allocating commingled production.

 

             If an agreement among the necessary parties cannot be reached, then the applicant shall file with the Commission, prior to commencing operations, the same information described in the preceding paragraph, excluding the statement that the parties have agreed, and in addition shall give written notice by certified mail to each person who owns an interest in the tract where production is to be commingled.  The notice shall state that anyone who objects to the proposed operation may file a protest with the Commission within 30 days.  The applicant shall provide the Director with a copy of the notice and a list of the addressees.  If any such owner, or the Commission itself, does not file written objection to the application within 30 days after receiving notice, then the application shall be approved.  If any such owner, or the Commission itself, files written objection to the application within 30 days after receiving notice, then the application shall be heard in accordance with the rules of the Commission.

 

             Rule 6:  An operator may allocate the commingled production from the Dakota, "J" Sand, Codell, Niobrara, Sussex and Shannon Formations underlying lands subject to these rules, provided the method is equitable to all of the persons sharing in the costs and/or proceeds from the well and a description of the method to be used is provided to all of such persons with notification of their right to object to the Commission within 30 days.  The applicant shall provide the Director with a copy of the notice and a list of the addressees.  However, any allocation method shall be subject to the Commission's right to object on its own account or upon application of any interested party.  Any objection or application filed with the Commission shall be filed within 30 days after receipt of notice.  If no such party, nor the Commission itself, objects to the proposed allocation method, then the operator may allocate production without action by the Commission.

 

             Upon objection or application the Commission shall hear the matter in accordance with the rules of the Commission and may approve an allocation method if the method is equitable and has been approved in writing by (1) those persons who own at least 80% of the cost‑bearing interests in each Formation from which commingled production will be obtained, and (2) by the owners of at least 80% of the cost‑free interests, such as royalties, overriding royalties and production payments, in each Formation from which commingled production will be obtained.


 

             Rule 7:  Any application, protest or objection filed pursuant to these rules shall be subject to the rules of practice and procedure of the Commission; however, in the event of a conflict between the terms and provisions of these rules and the Commission's rules of practice and procedure, the terms and provisions of these rules shall control.

 

             IT IS FURTHER ORDERED, that the provisions contained in the above order shall become effective forthwith.
