REPORT OF THE COMMISSION
The Commission heard this matter on December 15, 2014, at the Colorado Oil and Gas Conservation Commission, 1120 Lincoln Street, Suite 801, Denver, Colorado, upon application for an order to approve an additional 46 horizontal wells, for a total of up to 48 horizontal wells within an approximate 640-acre drilling and spacing unit established for Section 30, Township 9 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 22, 2011, the Commission entered Order No. 535-3 which established 160 approximate 640-acre drilling and spacing units for certain lands including the Application Lands and allowed one horizontal well in each unit, for the production of oil, gas and associated hydrocarbons from the Niobrara Formation. Section 30, Township 9 North, Range 59 West, 6th P.M. is subject to this Order for the Niobrara Formation.
5. On December 12, 2011, the Commission entered Order No. 535-102 which approved up to two horizontal wells within a drilling and spacing unit established for Section 30, Township 9 North, Range 59 West, 6th P.M., with the treated interval of the wellbore to be located no closer than 600 feet from the boundaries of the drilling and spacing unit, and the treated interval of the second wellbore shall be no closer than 1,200 feet to the first horizontal wellbore without exception being granted by the Director, for the production of oil, gas and associated hydrocarbons from the Niobrara Formation.
6. On October 16, 2014, 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 an additional 46 horizontal wells, for a total of up to 48 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 productive interval of the wellbore to be located no closer than 300 feet from the unit boundaries, and no closer than 100 feet from the productive interval of any other wellbore located within the same bench of the Niobrara Formation in the unit, and no closer than 50 feet from the productive interval of any other wellbore located in a Niobrara Formation bench above or below the Niobrara Formation bench where that wellbore is located in the Unit, without exception granted by the Director:
Township 9 North, Range 59 West, 6 th P.M.
Section 30: All
7. Applicant stated that the proposed wells shall be located on no more than four wellpads within the drilling and spacing unit.
8. On November 24, 2014, 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 that the Applicant is an owner with the right to drill wells in the Application Lands.
10. Geologic testimony and exhibits submitted in support of the Application by Paul Fears, Geologist for Carrizo, showed that the Niobrara Formation to be uniform in thickness and underlying the Application Lands. An isopach map of the interval from the top of the Niobrara Formation to the top of the Codell Formation showed the total thickness of the Niobrara averages approximately 315 feet.
11. Engineering testimony and exhibits submitted in support of the Application by Andrew R. Agosto, Vice President of Business Development for Carrizo, showed that using reservoir properties, determined from performance of actual wells drilled by Carrizo as a basis for modeling, analog development scenarios resulted in efficient drainage of an area of approximately 35 acres per wellbore.
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 received no protests, and based on the Hearing Officer review of the Application under Rule 511, the Commission should enter an order to approve an additional 46 horizontal wells, for a total of up to 48 horizontal wells, within an approximate 640-acre drilling and spacing unit established for Section 30, Township 9 North, Range 59 West, 6th P.M., for the production of oil, gas and associated hydrocarbons from the Niobrara Formation.
