REPORT OF THE COMMISSION
The Commission heard this matter on August 20, 2012, 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 four horizontal wells
within an approximate 640-acre drilling and spacing unit established for Section
22, Township 3 North, Range 63 West, 6th P.M., for the production of
oil, gas and associated hydrocarbons from the Niobrara Formation.
FINDINGS
The Commission finds as follows:
1.
Marathon Oil Company (“Marathon” 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 April 27, 1988, the Commission adopted Rule 318A, which among other
things, allowed certain drilling locations to be utilized to drill or twin a
well, deepen a well or recomplete a well and to commingle any or all Cretaceous
Age Formations from the base of the Dakota Formation to the surface. Rule 318A.
supersedes all prior Commission drilling and spacing orders affecting well
location and density requirements of Greater Wattenberg Area wells. On December 5, 2005, Rule 318A
was amended, among other things, to allow interior infill and boundary wells to
be drilled and wellbore spacing units to be established. On August 8, 2011, Rule 318A was
again amended, among other things, to address drilling of horizontal wells.
Section 22, Township 3 North, Range 63 West, 6th
P.M. is subject to this Order for the Niobrara Formation.
5.
On June 27, 2011 (Corrected February 14, 2012), the Commission issued
Order No. 407-560 which, among other things, established nine 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, with the treated interval of the wellbore to be located no
closer than 460 feet from the unit boundaries.
Section 22, Township 3 North, Range 63 West, 6th P.M. is
subject to this Order for the Niobrara Formation.
6.
On December 12, 2011, the Commission issued Order No. 407-528 which,
among other things, approved two horizontal wells within each unit, with the
treated interval of the wellbore to be located no closer than 460 feet from the
unit boundaries. Section 22,
Township 3 North, Range 63 West, 6th P.M. is subject to this Order
for the Niobrara Formation.
7.
On June 21, 2012, Marathon, 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 four 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 surface locations consistent
with Rule 318A and the treated interval of the wellbore to be located no closer
than 460 feet from the unit boundaries, without exception being granted by the
Director:
Township 3 North, Range 63 West, 6th P.M.
Section 22: All
8.
On August 7, 2012, Marathon, 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 Tricia
Clarke, Land Professional for Marathon, showed that the Applicant has partially
leased the mineral interests in the Application Lands, that the Application
Lands are both state and private fee leases and that the interested parties
received notice of the Application.
10.
Geologic testimony and exhibits submitted in support of the Application by
Matthew Humphreys, Advanced Senior Geologist for Marathon, showed that the
Niobrara Formation underlies most of the DJ Basin in eastern Colorado,
southeastern Wyoming, and western Nebraska.
An isopach map of the Niobrara Formation showed total thickness of the
Niobrara Formation ranges from 275 to 285 feet in 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 of the Application Lands showed the
Niobrara Formation to be consistent, continuous, and underlying all the
Application Lands as a common source of supply.
11.
Engineering testimony and exhibits submitted in support of the Application by
Tara Watson, Reservoir Engineer for Marathon, showed estimated ultimate recovery
(“EUR”) values from 40 to 472 MBO; and a drainage area ranging from 46 to
534-acres, with an average of 177-acres. EUR and drainage estimates (which vary
from 29 to 507-acres for horizontal wells) for the analogous Silo field were
included in Applicant’s engineering analysis.
Testimony concluded granting the proposed spacing application will result
in efficient and economic development of Application Lands.
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.
Marathon
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 up to four horizontal
wells within an approximate 640-acre drilling and spacing unit established for
Section 22, Township 3 North, Range 63 West, 6th P.M., for the
production of oil, gas and associated hydrocarbons from the Niobrara Formation.
ORDER
NOW, THEREFORE IT IS ORDERED, that up to four horizontal wells within an
approximate 640-acre drilling and spacing unit established for the
below-described lands, are hereby approved, for the production of oil, gas and
associated hydrocarbons from the Niobrara Formation, with the surface locations
consistent with Rule 318A and the treated interval of the wellbore to be located
no closer than 460 feet from the unit boundaries, without exception being
granted by the Director:
Township 3 North, Range 63 West, 6th P.M.
Section 22: All
IT IS FURTHER ORDERED,
that the provisions contained in the above order shall become effective
immediately.
IT IS FURTHER ORDERED, that the Commission expressly reserves its right, after
notice and hearing, to alter, amend or repeal any and/or all of the above
orders.
IT IS FURTHER ORDERED, that under the State Administrative Procedure Act the
Commission considers this Order to be final agency action for purposes of
judicial review within 30 days after the date this Order is mailed by the
Commission.
IT IS FURTHER ORDERED, that an application for reconsideration by the Commission
of this Order is not required prior to the filing for judicial review.
ENTERED this
day of August, 2012, as of
August 20, 2012.
