REPORT OF THE COMMISSION

 

            The Commission heard this matter on December 12, 2016, at the Colorado Oil and Gas Conservation Commission, 1120 Lincoln Street, Suite 801, Denver, Colorado, upon application for an order to: 1) vacate an approximate 1280-acre drilling and spacing unit established by Order No. 535-519 for Sections 5 and 6, Township 4 South, Range 64 West, 6th P.M., for the production of oil, gas and associated hydrocarbons from the Niobrara Formation; and 2) establish an approximate 640-acre drilling and spacing unit for Section 6, Township 4 South, Range 64 West, 6th P.M., and approve up to one horizontal well within the unit, for the production of oil, gas, and associated hydrocarbons from the Niobrara Formation.

 

FINDINGS

 

The Commission finds as follows:

 

1.         ConocoPhillips Company (Operator No. 19160) (“ConocoPhillips” or “Applicant”) 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 Oil and Gas Conservation Commission requires that, on unspaced lands, 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.  Section 6, Township 4 South, Range 66 West, 6th P.M., is subject to this Rule for production of oil, gas, and associated hydrocarbons from the Niobrara Formation.

 

5.           On November 29, 2011, effective October 31, 2011, the Commission entered Order No., 535-97, which established 25 approximate 640-acre drilling and spacing units for certain lands located in Townships 4 and 5 South, Ranges 64 and 65 West, 6th P.M., and approved up to two horizontal wells within each unit, with surface locations being located anywhere within the unit or surrounding lands but the lateral of such well may not enter the Niobrara Formation any closer than 300 feet from the section line, with the treated interval of the permitted wellbore to be located no closer than 460 feet from the boundary of the unit and no closer than 920 feet from the treated interval of any other well in the unit producing from the Niobrara Formation, without exception being granted by the Director, for the production of oil, gas and associated hydrocarbons from the Niobrara Formation.  Section 6, Township 4 South, Range 64 West, 6th P.M., is subject to this Order.

 

6.         On August 13, 2014, effective as of July 28, 2014, the Commission entered Order No. 535-519, which vacated two approximate 640-acre drilling and spacing units established by Order No. 535-97 for Sections 5 and 6, Township 4 South, Range 64 West, 6th P.M., and established an approximate 1280-acre exploratory drilling and spacing unit for Sections 5 and 6, Township 4 South, Range 64 West, 6th P.M., and approving a total of up to two horizontal wells with the productive interval of the wellbore to be located no closer than 460 feet from the unit boundaries, and no closer than 960 feet from the productive interval of any other wellbore located in the unit, without exception being granted by the Director, for the production of oil, gas and associated hydrocarbons from the Niobrara Formation.

 

7.         On October 13, 2016, ConocoPhillips, by its attorneys, filed a verified application (“Application”) pursuant to §34-60-116, C.R.S., for an order to: 1) vacate an approximate 1280-acre drilling and spacing unit established by Order No. 535-519 for Sections 5 and 6, Township 4 South, Range 64 West, 6th P.M., for the production of oil, gas and associated hydrocarbons from the Niobrara Formation; and 2)  establish an approximate 640-acre drilling and spacing unit for the below-described lands (“Application Lands”) and to approve up to one horizontal well within the unit, for the production of oil, gas and associated hydrocarbons from the Niobrara Formation, with the productive interval of the wellbore to be located no closer than 460 feet from the unit boundaries, and no closer than 150 feet from the productive interval of any other wellbore located in the unit, unless an exception is granted by the Director:

 

Township 4 South, Range 64 West, 6th P.M.

Section 6:        All 

 

8.         On November 21, 2016, ConocoPhillips, by its attorneys, filed with the Commission a written request to approve the Application based on the merits of the verified Application and the supporting exhibits.  Sworn written testimony and exhibits were submitted in support of the Application.

 

            9.         Land testimony and exhibits submitted in support of the Application by Marie Giuffreda, Associate Landman for ConocoPhillips, showed that ConocoPhillips holds oil and gas leasehold interests and has a right to drill in the Application Lands.        

 

10.       Geologic testimony and exhibits submitted in support of the Application by Adam Mullins, Staff Geologist for ConocoPhillips, showed that the Niobrara Formation is present throughout the Application Lands, is approximately 320 feet thick, and is generally of uniform thickness throughout the Application Lands.

 

11.       Engineering testimony and exhibits submitted in support of the Application by Jeff Stine, Senior Reservoir Engineer for ConocoPhillips, showed that the drainage area for analog horizontal Niobrara Formation wells are estimated at 301.2 acres, and an approximate 640-acre drilling and spacing unit is therefore not less than the maximum area than can be efficiently, economically and effectively drained by a horizontal well producing oil, gas and associated hydrocarbons from the Niobrara Formation.

 

12.       The above-referenced testimony and exhibits show that granting the Application will allow more efficient reservoir drainage, will prevent waste, will assure a greater ultimate recovery of hydrocarbons, and will not violate correlative rights.

 

13.       ConocoPhillips agreed to be bound by oral order of the Commission.

 

14.       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, the Commission should enter an order to: 1) vacate an approximate 1280-acre drilling and spacing unit established by Order No. 535-519 for Sections 5 and 6, Township 4 South, Range 64 West, 6th P.M., for the production of oil, gas and associated hydrocarbons from the Niobrara Formation; and 2) establish an approximate 640-acre drilling and spacing unit for Section 6, Township 4 South, Range 64 West, 6th P.M., and approve up to one horizontal well within the unit, for the production of oil, gas, and associated hydrocarbons from the Niobrara Formation.

Section 6:        All 

 

3.         The productive interval of the wellbore will be located no closer than 460 feet from the unit boundaries, and no closer than 150 feet from the productive interval of any other wellbore located in the unit, unless the Director grants an exception.

 

IT IS FURTHER ORDERED:

 

1.         The provisions contained in the above order shall become effective immediately.
