FINDINGS

 

                        The Commission finds as follows:

 

                        1. EOG Resources, Inc. (“EOG”), 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.  Rule 318.a. of the Rules and Regulations of the Commission requires that wells drilled in excess of 2,500 feet in depth be located not less than 600 feet from any lease line, and located 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 Application Lands are subject to this Rule for the Niobrara Formation.

 

5.    On December 29, 2009, EOG, by its attorney, filed with the Commission a verified application for an order to establish 58 approximate 640-acre drilling and spacing units for the Application Lands for the production of oil and gas and associated hydrocarbons from the Niobrara Formation, and allow one horizontal well in each of the units with a bottom-hole location no closer than 600 feet from the boundaries of each unit.  

 

6.    No protests or interventions to EOG’s application were received by the Commission.  An administrative hearing was conducted before the staff of the Commission on February 9, 2010, during which EOG provided testimony and exhibits in support of the application.

 

7.  Testimony and exhibits in support of the application showed that EOG has either fully or partially leased the mineral interests in the Application Lands except in three 160-acre tracts and two 320-acre tracts, that all but two sections are private fee lands with few severed mineral interests in the area, and that surface owners were supportive of one horizontal well per 640 acres.

8.  Testimony and exhibits in support of the application showed that the Niobrara Formation is a sequence of chalks, marls, and limestones that were deposited in the Western Interior Seaway during Cretaceous time.  The rocks were deposited as deep water sediments and underlie most of the Denver-Julesburg Basin in parts of northeastern Colorado, southeastern Wyoming, and southwestern Nebraska.  A subsea structure map on top of the Niobrara Formation indicated regional dip is approximately one-half a degree to the west.  An isopach map of the Niobrara Formation showed total thickness ranges from approximately 250-290 feet under the Application Lands.  A type log for the Niobrara Formation showed that it consists of two members, the Smoky Hill Chalk and the Fort Hayes Limestone.  A stratigraphic cross-section, zigzagging across the Application Lands, showed the Niobrara Formation to be consistent, continuous, and underlying all the Application Lands as a common source of supply.

9.  Testimony and exhibits in support of the application showed that analysis of the Kern #43-33 Well, a vertical well producing from the Niobrara Formation located on adjacent lands, indicated that the estimated ultimate recovery (“EUR”) for said well is approximately 38,450 barrels of oil and the original oil-in-place (“OOIP”) is 769,293 barrels of oil, resulting in a corresponding drainage area of approximately 23 acres.  The first exploratory horizontal well drilled by EOG on the Application Lands, the Jake #2-01 H Well, has an EUR of 250,000 barrels of oil and an OOIP of 5,000,000 barrels of oil with a corresponding drainage area of approximately 152 acres.  The Silo field, 25 miles north in Wyoming, is a major field producing from the Niobrara Formation.   Since the early 1980s, 10,000,000 barrels have been produced from vertical and horizontal wells.  EUR and drainage estimates (which vary from 35 to 492 acres) for the Silo field were included in EOG’s engineering analysis.  Additional testimony indicated granting the proposed spacing application will result in efficient and economic development of Application Lands.   

10.  EOG agreed to be bound by the oral order of the Commission.

11.  Based on the facts stated in the verified application, having received no protests, and the testimony and exhibits having been considered by the Hearing Officer at an administrative hearing, the Commission should enter an order to establish 58 approximate 640-acre drilling and spacing units for the Application Lands, for the production of oil and gas and associated hydrocarbons from the Niobrara Formation, with no more than one horizontal well to be drilled in each unit from a surface location anywhere in the unit with the horizontal leg and bottom-hole location to be no closer than 600 feet from the boundaries of each  unit.

ORDER

 

NOW, THEREFORE, IT IS ORDERED, that the following 58 approximate 640-acre drilling and spacing units for the production of oil, gas and associated hydrocarbons from the Niobrara Formation are hereby established with no more than one horizontal well to be located in each of the units.  The surface location for each horizontal well shall be located anywhere upon the drilling and spacing unit, provided that the horizontal leg into the Niobrara Formation shall not be closer than 600 feet to the outside boundary of the drilling unit and the terminus of the horizontal leg shall not be any closer than 600 feet to the outside boundary of the drilling and spacing unit without exception being granted by the Director of the Oil and Gas Conservation Commission.
