This cause came on for hearing before the Commission on February 22,
2010, at 9:00 a.m., in Suite 801, The Chancery Building, 1120 Lincoln Street,
Denver, Colorado,
for an order to establish 58 approximate 640-acre drilling and spacing units for
the lands (“Application Lands”) listed below for production of oil and gas and
associated hydrocarbons from the Niobrara Formation:

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.
