REPORT OF THE COMMISSION
The Commission heard this matter on June 17, 2013, at the Two Rivers Convention
Center, 159 Main Street, Grand Junction, Colorado, upon application for an order
to establish an approximate 640-acre drilling and spacing unit for Section 30,
Township 10 North, Range 59 West, 6th P.M., and approve up to 13
horizontal wells within the unit, for the production of oil, gas, and associated
hydrocarbons from the Niobrara Formation.
FINDINGS
The Commission finds as follows:
1.
Carrizo Oil & 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.
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 30,
Township 10 North, Range 59 West, 6th P.M. is subject to Rule 318.a.
for the Niobrara Formation.
5.
On April 18, 2013, Carrizo Oil & Gas,
Inc. (“Carrizo” or “Applicant”),
by its attorneys, filed with the Commission pursuant to §34-60-116
C.R.S., a verified application (“Application”) for an order to establish an
approximate 640-acre drilling and spacing unit for the below-described lands
(“Application Lands”), and approve up to thirteen horizontal wells in the unit,
for the production of oil, gas and associated hydrocarbons from the Niobrara
Formation, with internal wellbores offset by 300 feet and unit boundary setbacks
of 600 feet. Applicant further requests that 100 foot “heel-and-toe” completed
interval setbacks from the unit boundaries perpendicular to the well laterals
apply so long as Applicant obtains exception location approvals pursuant to Rule
318.c. This exception location requirement for reduced unit boundary setbacks
shall not apply if superseded by a subsequent Commission Rule or Order.
Township 10 North, Range 59 West, 6th P.M.
Section 30:
All
The proposed wells shall be located on no more than one
wellpad per quarter quarter section within the drilling and spacing unit.
6.
On June 4, 2013 (Revised June 11, 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.
7.
On June 11, 2013, the Bureau of Land Management (“BLM”) filed a protest
to the Application.
8.
On June 11, 2013, Carrizo, by its attorneys, withdrew the request for the
100 foot “heel and toe” setbacks.
9.
On June 13, 2013, BLM withdrew its protest to the Application.
10.
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.
11.
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 345 feet thick and to be consistent, continuous, and underlying
all of the Application Lands.
12.
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.
13. 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.
14.
Carrizo agreed to be bound by oral order of the Commission.
15.
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 establish an approximate 640-acre
drilling and spacing unit for Section 30, Township 10 North, Range 59 West, 6th
P.M., and approve up to 13 horizontal wells within the unit, for the production
of oil, gas, and associated hydrocarbons from the Niobrara Formation.
ORDER

1.
An approximate 640-acre drilling and spacing unit for the below-described lands,
is hereby established, and up to 13 horizontal wells within the unit, are hereby
approved, for the production of oil, gas and associated hydrocarbons from the
Niobrara Formation, with the treated interval of the horizontal wellbore to be
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 30:
All
2.
The proposed wells shall be located on no more than one wellpad per quarter

required prior to the filing for judicial review.

8th
day of July, 2013, as of June 17, 2013.
