For the 160-acre drilling and spacing units established for the below-listed lands, two (2) wells shall be allowed to be optionally drilled into and produced from the Williams Fork Formation, with the permitted well to be located no closer than 600 feet from the lease line nor 1,200 feet from any other producible or drilling oil and gas well in the Williams Fork Formation.

5. Testimony presented at the administrative hearing indicated that extremely difficult topographic conditions are present in the above-described lands and that a thirty (30%) larger window in which a well could be located would reduce the amount of exception location requests by approximately forty (40%) percent. The permitted well should be located no closer than 400 feet from the boundaries of the unit and no closer than 800 feet from an existing W illiams Fork Formation well. In addition, upon adequate showing by an applicant, the Director should be allowed to grant exceptions to the permitted well locations for topographical reasons. Further, testimony was recounted from the February 22, 1994 hearing to show that correlative rights would not be harmed by a change in permitted well locations due to production typically not extending beyond the limited vertical and lateral natural fracture pattern and lithologic boundaries.

6. Based on the facts stated in the application, having received no protests, and having been heard by the Hearing Officers on March 16, 1994 and recommended for approval, the Commission should approve the application to change the permitted well location.

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 Williams Fork Formation of the Mesaverde Group described herein below, in addition to other applicable rules and regulations and policies and orders of the Commission, if any, heretofore adopted and not in conflict herein:
