REPORT OF THE COMMISSION

This cause came on for hearing before the Commission on July 17, 1989 at 8:30 a.m. in Room 101, State Education Building, 201 East Colfax Avenue, Denver, Colorado as a result of Order No. 451-12 which established a production restriction on wells located in the spaced area of the Lilli Field and further ordered that operators in the field and any interested parties were to appear at the hearing scheduled for July 17, 1989, and present additional information including results of a field wide pressure survey conducted in June 1989, concerning production practices in the field.

FINDINGS

The Commission finds as follows:

1. The Commission has jurisdiction over the subject matter embraced in the notice of the aforesaid hearing and of the parties interested therein, as well as jurisdiction of promulgate the hereinafter prescribed order.

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

3. By Order No. 451-12, commencing February 1, 1989, the maximum monthly allowable for any one month, for wells completed as producing with gas to oil ratios of 3000 cubic feet of gas per barrel of oil or less, hereinafter referred to as "Oil Wells" shall be 900 barrels of oil or 7,500 MCF of gas, whichever is produced first. A well shall be considered a "Gas Well" if it has a gas to oil ratio in excess of 3,000 cubic feet of gas per barrels of oil. The allowable for a gas well shall be 21,000 MCF of gas per month. There shall be no maximum allowable for liquid production for gas wells. No adjustment in this allowable for variation of the number of days in a month shall be made.

4. Testimony presented by the Lilli Field Technical Committee at the hearing indicated the field limits remain well defined, the change in the bottom hole pressure survey are larger in the oil leg than the gas area, that the original gas-oil contact has moved very little, and that the gas to oil ratio for oil wells has increased. The

- 1 -(451-14)

testimony was supplemented by Exhibits A and B.

5. Further testimony was presented in the form of written recommendations, Exhibit C, to the Commission. The main recommendations were to establish a maximum monthly allowable of 450 barrels of oil or 3750 MCF of gas for wells with a gas to oil ratio of 3,000 cubic feet per barrel or less. For wells with a gas to oil ratio greater than 3,000 cubic feet per barrel, the monthly allowable would be 30,000 MCF of gas; there would be no maximum allowable for liquid production from these wells.

6. Additional recommendations were that Rules 5, 6 and 7 of Order No. 451-12 be amended to make changes in the production allowable accounting system, that Rule 8 be deleted, and that operators and interested parties should appear at the September 1989 hearing of the Commission to report on production activities and make recommendations as needed, and report on efforts towards unitization.

7. The Commission should adopt the recommendation of the Lilli Technical Committee.

and that the recommendations of the Lilli Field Technical Committee are adopted.

Rule 1. Eighty (80) acres, more or less, drilling and spacing units shall be and the same are hereby established for the production of oil and associated hydrocarbons from the "D" Sand formation underlying the following described lands in the Lilli Field, Weld county, Colorado, to-wit:

Township 8 North, Range 58 West, 6th P.M. Section 4: All Section 8: All Section 5: All Section 9: All Section 6: All Section 17: NW/4 Section 7: All Section 18: N/2

Township 9 North, Range 59 West, 6th P.M. Section 36: S/2

Rule 2. Said drilling units shall consist of 80-acres, more or less, and shall consist of the E/2 and W/2 or the N/2 and S/2 of a governmental quarter section, with the unit designated by the operator of the first well drilled in the quarter section. The permitted well for each unit shall be located in the center of the NW/4 and the SE/4 of each quarter section with a tolerance of 200 feet in any direction. Well No. 15-5 Bringleson, located in the SW/4 SE/4 of said Section 5 and well No. 7-10 Federal, located in the SW/4 NE/4 of said Section 10 shall each be considered exceptions and be the permitted well for the unit to be designated by the operator. Exception to the permitted well locations may be granted by the Director, provided owners of the contiguous and cornering units file a waiver or consent in writing agreeing to the exception.

Rule 3. One hundred sixty (160) acre drilling and spacing units shall be and the same are hereby established for the production of gas and associated hydrocarbons from the "D" Sand underlying the following described lands in Weld County, Colorado, to-wit:

Rule 5. (a) Commencing August 1, 1989, the maximum monthly allowable for any one month, for wells completed as producing gas/oil ratios of 3,000 cubic feet of gas per barrel of oil or less, hereinafter referred to as "Oil Wells", shall be 450 barrels of oil or 3,750 MCF, whichever is produced first. There shall be no adjustment in this allowable for variation of the days in a month. A well shall be considered a "Gas Well" if it has a gas/oil ratio in excess of 3,000:1 cubic feet per barrel. The allowable for a Gas Well shall be 30,000 MCF per month. There shall be no maximum allowable for liquid production for Gas Wells. If, during the initial gas/oil ratio test, the well is determined to be an Oil Well in accordance with the above gas/oil ratio for production restriction purposes, the well shall remain an Oil Well, regardless of future increases in the gas/oil ratio of the well.

(b) The allowable for a well will be effective the month the well is perforated. A full month allowable will be in effect for that month.

(c) If a well produces less than its allowable for a given month ("Under Production"), the allowable for that well shall be increased the following month. Production in the following month will be allocated first to the Under Production form the prior month, and then to the base allowable for that month. The base allowable not produced for the current month will be carried forward to the following month as Under Production.

In no event shall a party carry forward to a following month more than one month's base allowable as a credit as Under Production. To the extent any operator may have Under Production prior to August 1, 1989, such operator may carry forward to August, 1989, the lesser of: (i) the amount of such Under Production; or (ii) the new revised base monthly allowable as set forth herein.

(d) Any Over Production shall be made up in the month following such Over Production.

(e) The foregoing allowable rules shall be applied on a lease basis for multiple wells with combined production facilities.

Rule 6. For wells drilled and completed in the Lilli Field after the effective date of this order, in areas spaced for oil production and which are completed with an initial gas/oil ratio in excess of 3,000 cubic feet per barrel, the allowable rate shall be half of a Gas Well or 15,000 MCF per month unless the well is the only producing well within the entire quarter section, in which case the well shall have the full Gas Well allowable.

- 6 -(451-14)

Rule 7. Preliminary monthly production data shall be submitted to the Commission and the other operators in the field on a letterhead format by the end of the month following production.

IT IS FURTHER ORDERED, that the above production restrictions shall remain in effect until September 30, 1989, and that the operators and any interested party in the Lilli Field shall appear at the September, 1989 hearing with the results and additional information concerning production practices in the field for the Commission to consider any amendments or changes to this order as deemed necessary and to report on efforts toward unitization of Lilli Field.
