REPORT OF THE COMMISSION

 

            The Commission heard this matter on July 29, 2013, at the offices of the Colorado Oil and Gas Conservation Commission, 1120 Lincoln Street, Denver, Colorado, upon application for an order to approve up to thirteen horizontal wells within an approximate 640-acre drilling and spacing unit established for Section 31, Township 10 North, Range 59 West, 6th P.M., for the production of oil, gas, and associated hydrocarbons from the Niobrara Formation.

 

FINDINGS

 

The Commission finds as follows:

 

1.         Carrizo Oil and Gas, Inc. (“Carrizo” or “Applicant”), 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.         On February 11, 2013, the Commission entered Order No. 535-272 which, among other things, established four approximate 640-acre drilling and spacing units, and approved one horizontal well within each unit, for the production of oil, gas and associated hydrocarbons from the Niobrara Formation. Section 31, Township 10 North, Range 59 West, 6th P.M. is subject to this Order for the Niobrara Formation.

 

5.         On February 11, 2013, the Commission entered Order No. 535-264 which, among other things, approve up to six horizontal wells within each of two approximate 640-acre drilling and spacing units, for the production of oil, gas and associated hydrocarbons from the Niobrara Formation.  Section 31, Township 10 North, Range 59 West, 6th P.M. is subject to this Order for the Niobrara Formation.

 

6.         On May 25, 2013, the Commission entered Order No. 535-312 which, among other things, pooled all interests in an approximate 640-acre exploratory drilling and spacing unit for certain lands, including the Application Lands, to accommodate the drilling of the Timbro 31-44-10-59 Well, for the development and operation of the Niobrara Formation.  Section 31, Township 10 North, Range 59 West, 6th P.M. is subject to this Order for the Niobrara Formation.

 

7.         On May 30, 2013, Carrizo, by its attorneys, filed with the Commission pursuant to §34-60-116, C.R.S., a verified application (“Application”) for an order to approve up to thirteen horizontal wells within an approximate 640-acre drilling and spacing unit established for the below-described lands (“Application Lands”) for the production of oil, gas and associated hydrocarbons from the Niobrara Formation, with the treated interval of the wellbore to be located no closer than 600 feet from the unit boundaries, and no closer than 300 feet from the treated interval of any other wellbore located in the unit, without exception being granted by the Director:

 

                    Township 10 North, Range 59 West, 6th P.M.

                    Section 31:          All

 

The proposed wells shall be located on no more than one wellpad per quarter quarter section within the drilling and spacing unit.

 

8.         On July 16, 2013, Carrizo, 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 Craig E. Wiest, Land Manager for Carrizo, showed the Applicant is an owner with the right to drill in the Application Lands.

 

10.       Geologic testimony and exhibits submitted in support of the Application by Paul Fears, the DJ Basin Geologist for Carrizo, included stratigraphic cross-sections and gross thickness isopach tests showing the Niobrara Formation is approximately 355 feet thick and to be consistent, continuous, and underlying all of the Application Lands.

 

11.       Engineering testimony and exhibits submitted in support of the Application by Stephen C. Peters, Manager of Reservoir Engineering for Carrizo, showed that analog wells, drilled by Carrizo on 300 feet internal wellbore setbacks with frac half-lengths of 75 feet, and the assumed lateral length of 5080 feet should exhibit an Estimated Ultimate Recovery (“EUR”) between 128.3 and 136.3 thousand oilfield barrels of oil (“MBO”) plus associated gas and processed natural gas liquids (NGLs).  This configuration will accommodate up to 13 wellbores in a 640-acre drilling and spacing unit with 600 feet unit boundary setbacks. Testimony concluded the economics of the project were sound.

 

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.       Carrizo agreed to be bound by oral order of the Commission. 

 

14.       Based on the facts stated in the verified Application, having resolved all protests, and based on the Hearing Officer review of the Application under Rule 511, the Commission should enter an order to approve up to thirteen horizontal wells within an approximate 640-acre drilling and spacing unit established for Section 31, Township 10 North, Range 59 West, 6th P.M., for the production of oil, gas, and associated hydrocarbons from the Niobrara Formation.
