IN THE MATTER OF THE PROMULGATION AND ESTABLISHMENT OF FIELD RULES TO GOVERN OPERATIONS IN THE SECOND WIND FIELD, CHEYENNE COUNTY, COLORADO Cause No. 463 Order No. 463-1

REPORT OF THE COMMISSION

This cause came on for hearing before the Commission on September 19, 1988, at 8:30 A.M., in Room 101, Education Building, 201 East Colfax, Denver, Colorado, after giving Notice of Hearing as required by law, on the verified application of Union Pacific Resources Company, for an order establishing 80-acre drilling and spacing units for the production of oil and associated hydrocarbons from the Morrow Sandstone formation underlying certain lands in Cheyenne County, Colorado.

FINDINGS

The Commission finds as follows:

1. Union Pacific Resources Company, as applicant herein, is an interested party in the subject matter of the above-referenced matter.

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. Evidence presented to the Deputy Director as Hearing Officer indicates that the Morrow formation constitutes a common source of supply of oil and associated hydrocarbons underlying the following described lands in Cheyenne County, Colorado to wit:

Township 16 South, Range 42 West, 6th P.M. Section 12: All Section 24: All Section 13: All Section 25: All Section 14: All Section 26: All Section 23: All Section 35: E/12 Section 36: All

Township 16 South, Range 41 West, 6th P.M. Section 7: All Section 30: All Section 18:All Section 31: All Section 19:All

Township 17 South, Range 41 West, 6th P.M.

Section 6: All Township 17 South, Range 42 West, 6th P.M. Section 1: All

5. In order to prevent the waste of oil and gas as defined by law, and to protect the correlative rights of all parties concerned; to prevent the drilling of unnecessary wells, and to insure proper and efficient development and promote conservation of the oil and gas resources of the State, an order should be made establishing 80-acre drilling and spacing units. The units should consist of 80-acres more or less, and consist of the E/2 and W/2 or the N/2 and S/2 of each quarter section of a governmental section with the unit designated by the operator of the first well in each quarter section. The permitted well for each 80-acre unit should be located within the NE/4 or SW/4 of a quarter section and no closer than 460 feet from the boundaries of the unit tract.

6. For purposes of conservation and to prevent waste, a maximum allowable of 100 MCF of gas per day per well should be imposed on the production of all wells at standard locations. For the above purposes and to protect correlative rights, a restriction of 300 barrels of oil and water per day per well at a standard location should be imposed, and that any well should be restricted by whichever production limit is reached first.

7. The Director, upon giving ten days notice to cornering and contiguous lease owners, after administrative hearing, should be able to permit exception locations throughout the entire Second Wind Field, upon a showing that a well has been drilled at the designated location as prescribed in the orders of this cause and the well is unproductive in the Morrow Sandstone formation interval and the operator of the drilling and spacing unit submits an Application to Drill accompanied by information indicating why the designated location was unproductive and why a well at the exception location should be productive and economically viable. Such exception location should be located no closer than 460 feet to the unit boundary and all such exception locations should have production restrictions equal to one-half that of wells drilled at standard locations.

8. On February 21, 1986, the Commission authorized Order No. 442-1 to be issued which established 40-acre drilling and spacing units for the production of oil and associated hydrocarbons from the Morrow formation with the permitted well to be located no closer than 330 feet to the boundaries of a quarter-quarter section for the following lands:

Township 16 South, Range 41 West, 6th P.M. Sections 7, 8, 17, 18, 19, and 20: All Township 16 South, Range 42 West, 6th P.M. Section 12, 13 and 24: All On September 21, 1987, the Commission authorized Order No. 442-2 which approved the Southwest Stockholm Unit Agreement and deleted the blow listed lands from Order No. 442-1:

Township 16 South, Range 41 West, 6th P.M. Section 8: Lots 5 and 6 a.d.a. S/2 spacing units and well location requirements applicable to any of the above described lands that are under Order No. 442-1 should be superseded by any order granted by the Commission under this application.

9. No protests to the application have been filed, and the Hearing Officer recommends approval of the application.

Township 17 South, Range 41 West, 6th P.M. Section 6: All Township 17 South, Range 42 West, 6th P.M. Section 1: All

Rule 2. The units shall consist of 80-acres more or less, and consist of the E/12 and W/2 or the N/2 and S/2 of each quarter section of a governmental section with the unit designated by the operator of the first well in each quarter section. The permitted well for each 80-acre unit shall be located within the NE/4 or SW/4 of a quarter section and no closer than 460 feet from the boundaries of the unit tract.

Rule 3. For purposes of conservation and to prevent waste, a maximum allowable of 100 MCF of gas per day per well shall be imposed on the production of all wells at standard locations. For the above purposes and to protect correlative rights; a restriction of 300 barrels of oil and water per day per well at a standard location shall be imposed, and that any well shall be restricted by whichever production limit is reached first.

(a.) Gas production for the purpose of determining the restriction shall include all gas sold, flared or re-injected, less that amount used on the unit and shall be measured by an orifice and recording meter in accordance with Rule 331 of the Colorado Oil and Gas Conservation Commission. Regular production reports shall be made to the Commission in accordance with Rule 307 of the Colorado Oil and Gas Conservation Commission and copies distributed to the other Operators on the field by each Operator for its own wells.

(b.) For the determination of the monthly gas production attributable to each well when production is to a central lease battery servicing more than one well, each well shall be allocated a theoretical production volume based upon a monthly production test of the well. This shall be done by calculating a theoretical production percent for each well on the lease and multiplying that percent by the total monthly lease production to calculate the total monthly production attributable to an individual well.

-- 5 --(463-1)

(c.) Overproduction shall be made up by underproducing in the month following such overproduction and overproduction in a given month shall not exceed the previous month's allowable. Underproduction shall be made up within two (2) months following the month of underproduction.

Rule 4. The Director. upon giving ten days notice to cornering and contiguous lease owners, after administrative hearing, shall be able to grant exception well locations when a well has been drilled and abandoned at the designated location as prescribed in the orders of this cause and the well is unproductive in the Morrow Sandstone interval and the operator of the drilling and spacing unit submits an Application to Drill accompanied by information indicating why the designated location was unproductive and why a well at the exception location should be productive and economically viable. Such exception locations shall be no closer than 460 feet to the unit boundary and all such exception locations shall have production restrictions equal to one-half that of wells drilled at standard locations.

IT IS FURTHER ORDERED, that all spacing units and well location requirements applicable to any of the above described lands that are under Order No. 442-1 shall be superseded by the hereinabove order, and that those portions of Order No. 442-1 shall be rescinded.

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