Township 6 South, Range 92 West, 6th P.M.

Section 8:        SW½ SW¼ (80-acre drilling and spacing unit)

Section 16:      NW¼ (160-acre drilling and spacing unit)

Section 23:      NW¼ NE¼ and NE¼ NW¼ (80-acre drilling and spacing unit)

FINDINGS

 

                        The Commission finds as follows:

 

            1.  Antero Resources Corporation (“Antero”), 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 pursuant to the Oil and Gas Conservation Act.

 

                        4.  Rule 318.a. of the Rules and Regulations of the Colorado Oil and Gas Conservation Commission requires wells drilled in excess of 2,500 feet in depth to be located not less than 600 feet from any lease line, and not less than 1,200 feet from any other producible or drilling oil or gas well when drilling to the same common source of supply. The below-listed lands are subject to this rule:

 

Township 6 South, Range 92 West, 6th P.M.

Section 8:        S½ SW¼

Section 16:      NW¼, SW¼ NE¼

Section 23:      NW¼ NE¼ and NE¼ NW¼

                                   

                        5.  On July 12, 2006, Antero, by its attorney, filed with the Commission a verified application for an order to establish various drilling and spacing units for the production of gas and associated hydrocarbons from the Williams Fork and Iles Formations for the below-listed lands and to allow the equivalent of one (1) well per 10 acres:

 

Township 6 South, Range 92 West, 6th P.M.

Section 8:        S½ SW¼ (80-acre drilling and spacing unit)

Section 16:      NW¼ (160-acre drilling and spacing unit)

Section 16:      SW¼ NE¼ (40-acre drilling and spacing unit)

Section 23:      NW¼ NE¼ and NE¼ NW¼ (80-acre drilling and spacing unit)

 

                        That as to all future Williams Fork Formation wells to be drilled upon the application lands, each well may be located anywhere downhole in the established drilling and spacing unit but no closer than one hundred (100) feet from the boundaries of the unit, without exception being granted by the Director, except that with respect to units or lease lines abutting or cornering lands for which the Commission has not at the time of the drilling permit application granted the right to drill 10-acre density wells, the well shall be located downhole no closer than 200 two hundred (200) feet from the boundary of the drilling unit so abutting or cornering such lands.  

 

                        That as to all future Iles Formation wells to be drilled upon the application lands within drilling and spacing units (granted pursuant to this aApplication), the well should be located downhole anywhere in the drilling and spacing unit but no closer than one hundred (100) feet from the boundaries of the unit without exception being granted by the Director of the Oil and Gas Conservation Commission.  It is provided however that in cases where the application lands abut or corner lands in respect of which the Commission has not at the time of drilling permit application granted the right to drill 10-acre density Iles Formation wells, the well should be located downhole no closer than four hundred (400) feet from the boundary or boundaries of the drilling unit so abutting or cornering such lands without exception being granted by the Director of the Oil and Gas Conservation Commission. 

 

                        That all Williams Fork Formation and Iles Formation wells drilled upon the application lands  will be drilled from the surface either vertically or directionally from no more than one pad located on a given quarter quarter section unless exception is granted by the Director of the Colorado Oil and Gas Conservation Commission.  In addition, wells drilled to the Iles Formation may only be drilled and completed in connection with drilling of wells to the Williams Fork Formation.

 

                        6.  On May 23, 2006, Antero, by its attorney, filed with the Commission a written request to approve the application based on the merits of the verified application and the supporting exhibits. 

 

·                        7.  Testimony and exhibits submitted in support of the application showed the proximity of the lands in the vicinity of the Application application lands which have been previously approved by the COGCC for increased density in the Williams Fork and Iles Formations.  Antero controls between 75 to 100 percent of the leasehold within the lands covered by each proposed drilling and spacing unit.  The multiple parcels require Antero to space the lands to coordinate efficient development.  Additional testimony indicated that all of the unleased mineral interest owners within or immediately abutting theApplication application  area have received notice of this Applicationapplication. We haveAntero has not received any notice of objection or protest to this Application application

 

8.  Testimony and exhibits submitted in support of the application showed that the Williams Fork and the Iles Formations are common sources of supply underlying the application lands.  The Williams Fork Formation is a highly discontinuous reservoir with units which were deposited in a series of sinuous fluvial systems.   The Iles Formation is a marine sandstone and shale sequence and contains a series of marine sandstone members know as the Rollins, Corcoran, and Cozette.  Additional testimony indicated that the median channel width of the Williams Fork Formation is approximately four hundred (400) feet.

 

9.  Testimony and exhibits submitted in support of the application described the pilot projects at Grand Valley and Rulison Fields to show that these infill drilling programs are increasing the recovery of gas in the pilot by contacting “new” gas.  Additional testimony showed that the wells drilled on 10- acre density are tracking closely to the wells drilled on 80 acres and 40 acres.

 

                        10.  Testimony and exhibits presented at the administrative hearing showed that increasing well density from twenty (20) to ten (10) acres has increased estimated ultimate recovery by 9.09 BCF within the development area located nearby in Section 32, Township 6 South, Range 92 West, 6th P.M.

 

11.  Testimony and exhibits submitted in support of the application showed that wells will have a 14.4% rate of return and 5 year payout. These economics meet Antero’s requirement for drilling the wells.  Additional testimony indicates that wells must be drilled on less than 20- acre well density in order to effectively drain the reservoir.

 

12.  Testimony and exhibits submitted in support of the application showed that the Iles Formation in the application area concerned with this testimony could not be economically developed with wells drilled and completed only in the Iles Formation. The rates of return are well below 5% and the wells do not pay out in any reasonable time frame. Reserves from the Iles Formation would not be recovered in the foreseeable future unless they are completed as a part of the Williams Fork Formation wells drilled at the same location.

 

                                                                                      

13.       The above-referenced testimony and exhibits show that the proposed drilling and spacing units will allow more efficient reservoir drainage, will prevent waste, will assure a greater ultimate recovery of gas, and will not violate correlative rights.

 

                        14.  Antero Resources Corporation agreed to be bound by oral order of the Commission.

 

                        15.   Based on the facts stated in the verified application, having received no protests and based on the Hearing Officer review of the application under Rule 511.b., the Commission should enter an order to establish various drilling and spacing units for the production of gas and associated hydrocarbons from the Williams Fork and Iles Formations for the below-listedcertain lands in Township 6 South, Range 92 West, 6th P. M. and to allow the equivalent of one (1) well per 10 acres.
