NO. 517-7
LAS ANIMAS COUNTY, COLORADO
REPORT OF THE COMMISSION
This cause came on for hearing before the Commission on February 12, 2002, at
10:00 a.m. in the Raton Room, Holiday Inn Trinidad, 3125 Toupal Drive, Trinidad,
Colorado on the application of Evergreen Resources, Inc., for an order to vacate
Order Nos. 517-1 and 517-2.
FINDINGS
The Commission finds as follows:
1. Evergreen Resources, Inc., as applicant herein, is an interested party 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. On December 3, 1998, the Commission issued Order No. 517-1, which established
160-acre drilling and spacing units for the below-listed lands in the Lorencito
Field for the production of gas and associated hydrocarbons from the Vermejo
Formation with the permitted well to be located no closer than 600 feet from the
boundaries of the unit.

5. On February 23, 1999, the Commission issued Order No. 517-2, which pooled all
interests in twenty-one (21) 160-acre drilling and spacing units located in
Sections 3, 8, 9, 10, 15, 16, 17, and 22 of Township 34 South, Range 66 West,
6th P.M. for the development and operation of the Vermejo Formation.
6. On December 11, 2001, Evergreen Resources, Inc., by its attorney filed with
the
Commission a verified Application for an order to order to vacate Order Nos.
517-1 and 517-2 and place the lands under the provisions of the Rules and
Regulations of the Commission to allow the necessary latitude to more fully
develop production of coalbed methane gas from the Vermejo Formation.
7. Testimony and exhibits presented at the administrative hearing described the
area involved in Evergreen’s infill drilling, the computer modeling study and
the assumptions used in the study.
8. Testimony and exhibits presented at the administrative hearing indicated that
five (5) wells per section is the optimum number of wells to be drilled. The
results of the computer modeling study indicate that five (5) wells per section
will yield a higher cumulative production than four (4) wells per section. An
additional 2.2% of the Original Gas in Place can be recovered by drilling five
(5) wells per section instead of four (4) wells per section. Additional drilling
of six (6) or seven (7) wells per section yields very small increases in percent
of gas recovered.
9. Testimony and exhibits presented at the administrative hearing indicated the
comparison production history from wells drilled on a spacing of four (4) wells
per section to production history from wells drilled on a spacing of five (5)
wells per section.
10. Testimony and exhibits presented at the administrative hearing indicated the
drainage pattern is an elliptical pattern and that more than four (4) wells are
needed per section to insure complete drainage of the reservoir.
11. Approval of the application would prevent waste, protect correlative rights
and more efficiently recover coalbed methane gas reserves.
12. At the time of the administrative hearing, Evergreen Resources Inc. agreed
to be bound by oral order of the Commission.
13. Based on the facts stated in the verified application, having received no
protests and having been heard by the Hearing Officer who recommended approval,
the Commission should approve an order to vacate Order Nos. 517-1 and 517-2 and
place the lands under the provisions of the Rules and Regulations of the
Commission to allow the necessary latitude to more fully develop production of
coalbed methane gas from the Vermejo Formation.
ORDER
NOW, THEREFORE IT IS ORDERED, that Order Nos. 517-1 and 517-2 are hereby vacated
and the lands described below shall be placed under the provisions of the Rules
and Regulations of the Colorado Oil and Gas Conservation Commission.
