March 20, 2014
IT APPEARING THAT:
1. By letter received December 4, 2013, Aurora Gas, LLC (Aurora) requested an exception
to the drilling units and wells spacing requirements of 20 AAC 25.055(a)(2) and (4) to
allow the drilling, perforating, completing, testing and production of gas development
wells within 3,000 feet of other existing gas wells, within the same section, and within
1,500 feet from a property line where the owner or landowner is not the same on both
sides of the line. Aurora seeks the exception for the undefined Beluga and Upper Tyonek
Gas Pools. In addition, Aurora requested an exception to the commingling restrictions of
20 AAC 25.215(b) to allow commingling of production within the same wellbore from
the undefined Beluga and Upper Tyonek Gas Pools.
2. Pursuant to 20 AAC 25.540, the Alaska Oil and Gas Conservation Commission
(AOGCC) tentatively scheduled a public hearing on Aurora's requests for January 23,
2014. On December 19, 2013, the AOGCC published notice of the opportunity for that
hearing on the State of Alaska's Online Public Notice website and on the AOGCC's
website, electronically transmitted the notice to all persons on the AOGCC's email
distribution list, and mailed printed copies of the notice to all persons on the AOGCC's
distribution list. On December 20, 2013, the notice was published in the ANCHORAGE
DAILY NEWS.
3. Pursuant to 20 AAC 25.055(d)(1), Aurora sent, by certified mail, notice of the spacing
exception application to all owners, landowners, and operators of all properties within
3,000 feet of the proposed Nicolai Creek Field affected area. Aurora provided the
AOGCC a copy of the notice, date of mailing, addresses to which the notice was sent,
and copies of the certified mail return receipts.
4. No protest to the applications or request for hearing was received.
5. Because Aurora provided sufficient information upon which to make an informed
decision, the requests can be resolved without a hearing.
6. The tentatively scheduled public hearing was vacated on January 22, 2014.

FINDINGS:
1. Requests: The requests for exceptions to 20 AAC 25.055(a)(2) and (4) and 20 AAC
25.215(b) apply to the shallow gas and potential gas sands of the Beluga Formation
(Beluga) and the upper portion of the Tyonek Formation (Upper Tyonek) of the proposed
Nicolai Creek Field affected area, located in Sections 17 (partial), 18 (partial), 19
(partial), 20, 29, 30, 31, and 32 of Township 11 North, Range 12 West, Seward Meridian.
2. Operator: Aurora is the owner and operator of the Nicolai Creek Unit (NCU) and is the
operator of the surrounding oil and gas leases proposed to be included in the Nicolai
Creek Field affected area at this depth interval. The area of interest is located on the
western side of the Cook Inlet Basin, Kenai Peninsula Borough, Alaska.
3. Subsurface Estate Landowners: The State of Alaska, Department of Natural Resources,
Division of Oil and Gas (DNR) is the subsurface estate owner of the leases that make up
the proposed Nicolai Creek Field affected area.
4. Surface Estate Landowners: Surface estate landowners in the proposed Nicolai Creek
Field affected area and within 3,000 feet of the proposed affected area are the State of
Alaska, Department of Natural Resources, Division of Oil and Gas (DNR), Mental
Health Trust, and Cook Inlet Region Incorporated.
5. Owners and Operators: Other owners and operators within 3,000 feet of the proposed
Nicolai Creek Field affected area are Apache Alaska Corporation (Apache), Buccaneer
Alaska, LLC, ConocoPhillips Alaska, Inc. (ConocoPhillips), and Hilcorp Alaska, L.L.C.
(Hilcorp).
6. Leases: The State of Alaska leases that make up the proposed Nicolai Creek Field
affected area are vertically segregated by depth with different owners (lessees). With the
exception of ConocoPhillips' 25 percent working interest in lease ADL 17585, Segment
4, Aurora owns 100 percent of the working interest in the shallow gas rights of the
Beluga and Upper Tyonek. Apache and Hilcorp are holders of the deep rights in the
DNR leases that underlie the proposed Nicolai Creek Field affected area.
The five leases that comprise the proposed Nicolai Creek Field affected area are held by
production.
7. Conservation Orders: There are currently three Conservation Orders (CO) regarding
spacing exceptions within the Nicolai Creek area: CO 478, C0623, and C0635A, for
NCU Nos. 1, 2, and 9; for NCU No. 11, and for NCU No. 10, respectively.
8. Exploration and Production History: Nicolai Creek Field was discovered in 1966.
Sustained production from the field commenced in April 1969. Currently, there are six
producing gas wells within the Nicolai Creek Field. The wells produce or have produced
gas from the Tsuga 2-5 interval of the Beluga to the Carya 2-6 interval of the Upper
Tyonek.
Nicolai Creek Field produces from stratigraphically discontinuous sandstones of the
Beluga and Upper Tyonek. Material balance analysis indicates that the wells drain

limited areas ranging from 25 to 155 acres, far smaller than the statewide drilling unit of
a governmental section for a gas pool specified under 20 AAC 25.055(a)(4).
9. The AOGCC received no comments, objections or protests in response to the public
notice regarding the proposed exception to the spacing requirements of 20 AAC 25.055
and the request for an exception to the commingling restrictions of 20 AAC 25.215(b).
10. The AOGCC received no comments, objections or protests in response to the notice of
the spacing exception application sent via certified mail to all owners, landowners, and
operators of all properties within 3,000 feet of the proposed Nicolai Creek Field affected
area.
11. Beluga and Upper Tyonek have similar pressure gradients, ranging from 0.45 psi/ft to
0.52 psi/ft.
CONCLUSIONS:
1. Aurora requests approval for an exception to the spacing requirements of 20 AAC
25.055(a)(2) and (4) and an exception to commingling restrictions of 20 AAC 25.215(b)
for the Nicolai Creek Field affected area, as proposed, covering approximately 2,580.30
acres of lands, both outside and within the Nicolai Creek Unit. Under AS 31.05.170(5),
"Field" means a general area which is underlain or appears to be underlain by at least one
pool, and includes the underground reservoir containing oil or gas; and the words "pool"
and "field" mean the same thing when only one underground reservoir is involved, but
"field" unlike "pool" may relate to two or more pools.
In considering the definition of "Field", subsurface control is inadequate to justify
inclusion of all lands, as proposed by Aurora, into the Nicolai Creek Field affected area.
2. Nicolai Creek Field is a mature gas production development. An exception to the well
spacing provisions of 20 AAC 25.055(a)(2) and (4) is necessary to allow more
expeditious drilling and production of new wells on closer spacing to facilitate
development of the limited -area reservoirs and to optimize resource recovery within the
field. Revising well spacing provisions for these undefined Beluga and Upper Tyonek
Gas Pools will not promote waste, jeopardize correlative rights, or result in an increased
risk of fluid movement into freshwater. Revising well spacing provisions for these
undefined Beluga and Upper Tyonek Gas Pools will not promote waste or jeopardize
correlative rights to potential oil and gas pools within the Lower Tyonek or deeper
formations.
3. Correlative rights of owners and landowners of offset acreage that lie outside of the
Nicolai Creek Field, as defined by Township Range, Section and Meridian, will be
protected by a 1,500-foot property line set -back requirement that conforms with
regulations 20 AAC 25.055(a)(2) for a well drilling to or being recompleted in the
undefined Beluga or Upper Tyonek Gas Pools.
4. Commingling of production from the Beluga and Upper Tyonek reservoirs when
bottomhole pressures are similar in the two formations, will extend the economic life of
the well by increasing production rate and thereby should increase the economically
recoverable reserves from the well and by extension the field.
Conservation Order 687
March 20, 2014
Page 4 of 6
Using a ratio of calculated reserves between the Beluga and Upper Tyonek reservoirs in
the individual wells will provide an acceptable method of allocating production between
the two formations.
NOW THEREFORE IT IS ORDERED:
The AOGCC approves Aurora's December 4, 2013 application for:
An order granting an exception to the drilling units and wells spacing requirements of 20
AAC 25.055 to allow the drilling, perforating, completing, testing and production of gas
development wells for the undefined Beluga and Upper Tyonek Gas Pools within the below
described Nicolai Creek Field with no restrictions as to well spacing, except that no gas well
shall be completed less than 1,500 feet from an external property line of the Field, as defined
by Township, Range, Section and Meridian, where the owners and landowners are not the
same on both sides of the line.

Re: Docket No. CO-13.27. The application of Aurora Gas, LLC (Aurora) for exceptions to
the spacing requirements of 20 AAC 25.055 and commingling requirements of 20 AAC
25.215(b).
Aurora by letter received December 4, 2013, requests the Alaska Oil and Gas Conservation
Commission (AOGCC) issue an order for an exception to the spacing requirements of 20 AAC
25.055 to allow the drilling, perforating, completing, testing and production of gas development
wells for all undefined gas pools within the Nicolai Creek Field with no restrictions as to well
spacing, and within 1,500 feet from a section line; and an exception to the commingling
restrictions of 20 AAC 25.215(b) to allow commingling of production within the same wellbore
from the Beluga and Upper Tyonek formations.
The AOGCC has tentatively scheduled a public hearing on this application for January 23, 2014
at 9:00 a.m. at the Alaska Oil and Gas Conservation Commission, at 333 West 7t' Avenue, Suite
100, Anchorage, Alaska 99501. To request that the tentatively scheduled hearing be held, a

Re: Application for Field -Wide Well Spacing and Commingling Exceptions
Nicolai Creek Unit "
Dear Ms. Foerster: AW
Pursuant to 20 AAC 25.055 (d) and 20 AAC 25.215 (b), Aurora Gas, LLC (Aurora) hereby requests
approval for the following two exceptions within the onshore Nicolai Creek Gas Field (and directional
offshore from onshore surface to shallow Beluga and Upper Tyonek targets, usually above 5000'
TVD): 1) to allow the drilling, perforating, completing, testing and production of wells within 3,000
feet of other existing gas wells in the Nicolai Creek Unit, within the same section, and within 1,500
feet from a section line (20 AAC 25.055) and 2) to commingling of any or all Beluga and Upper
Tyonek sands which are gas productive in the Field (20 AAC 25.215). Aurora requests that these
Exceptions apply to all wells, both existing and future, within the boundaries described in the attached
Exhibit A and shown on the attached maps, onshore and directional from onshore to shallow offshore.
The Nicolai Creek Field is located on the west side of the Cook Inlet in the Kenai Borough. A plat
depicting the lands is attached; lands in Sections 17, 19, 20, 29, 30, 31, and 32 in Township 11 North,
Range 12 West, Seward Meridian are included in the Field and in this request.
Currently, there are 6 active wells in this Field area, all Unit wells: Nicolai Creek Unit #1B, #2, #3, #9,
# 10, and # 11. The wells produce or have produced gas from the Tsuga 2-5 interval of the Beluga to
the Carya 2-6 interval of the Upper Tyonek. There are currently three Commission Orders regarding
spacing exceptions in the Field: CO 478, CO 623, and CO 635A, for NCU #1, 2, and 9; for NCU #11,
and for NCU # 10, respectively. A commingling exception Order is currently needed to produce the
Upper Completion of the NCU #2, recompleted in September and October of 2013, which would
commingle two lower Beluga sands and an Upper Tyonek sand. This requested Order would allow for
production of this commingled completion and others that may occur in the future.
The reasons for this request are two -fold: 1) this will allow more expeditious drilling and production
of new wells on closer spacing to facilitate development of the limited -area reservoirs, and 2)
economics dictate that we commingle as many sand intervals as possible to maximize production as
the wells start to deplete. The spacing exception will allow for increased well densities and better
recovery of reserves -comparing volumetric calculations to material balance analysis (P/Z vs.
cumulative production plots), the wells drain limited areas —see attached Well and Reservoir Data
spreadsheet, which shows estimated drainage areas of 25 to 155 acres, far less than an entire section.
There are several separate fault blocks in the Field, and most producing sands are stratigraphically
discontinuous. Nonetheless, there is good pressure and production information which allows for
prudent reservoir management. There are currently at least 15 Beluga sands ("Tsuga 2-5 through 2-
8") and 10 Upper Tyonek sands ("Carya 2-1 to 2-6") that produce or have produced in the Field, from
depths of about 920' TVD to 3570' TVD. Correlations between wells throughout the Field are usually
done on the basis of the major coals, which mark the changing intervals and which are fairly
consistent. Sands are then correlated based on the coals and sand lobes beneath the coals. Most of the
wells have multiple selective completions, with packers and sliding sleeves to isolate selected intervals
from one another for differing pressure or water -production reasons. By allowing commingling, as
pressures equalize, multiple completions can be flowed simultaneously to maximize production and
improve economics.

The virgin pressure gradients are fairly consistent throughout the field, with gradients for shallow
formations as high as 0.52 psi/ft and for deeper formations as low as 0.45 psi/ft. Using Expected
Ultimate Recoveries (EUR's) from P/Z plots to back -calculate drainage areas from using volumetric
reserves methods, the calculated drainage areas of most reservoirs are fairly small, 25-50 acres in the
South (# 1 B, #2, #9, and # 11) to as large as 100-155 acres in the North (#3 and # 10). There are several
faults dissecting the Field, and at least 5 different fault blocks produce. The structure and stratigraphy
that limit the drainage areas make it necessary to drill multiple wells in a section and at closer -than -
legal spacing to recover the gas in place. Due to the limited reserves per well, commingling enhances
the economics by accelerating recoveries and economizing completion costs. Both of these
Exceptions will result in recovery of more, not less, gas from the leases. Thus, waste will not occur in
the overall field.
The loss of producible gas ("waste") will not likely occur with the comingling of production. Zones
are not commingled until individual bottom -hole pressures of the zones are close to each other, based
on current SIP's after the individual interval tests. While there still may be cross -flow from the higher -
pressured zone to the lower -pressured zone when intervals are commingled, the pressures will
equalized as long as neither zone produces significant water. It is believed that any such "charging
gas" resulting from cross flow will be produced as pressures equalize and drop simultaneously with
production. The attached subsurface pressure map, for Aurora's annual reservoir surveillance reporting
required by CO 478A indicates the similarities of pressures in the south.
Allocations can be made on the basis of several parameters: based on volumetric reserves, log
analyses, production test data, and reserves analysis, production can be estimated from the separate
Beluga and Tyonek formations by at least three methods: 1) on the basis of individual tests, 2) on the
basis of estimated reserves, and 3) on the basis of net pay. The reserves basis is probably the best and
most accurate allocation method, if initial production rates from tests are essentially proportional to
the reserves. See the attached Well and Reservoir Data sheet indicating reserves, producing depths,
pressures, and producing rates, all of which provide some means of allocating production. Thus,
proper allocation, while not being exact, can be done on a reasonable basis.
Aurora is the lessee and Unit Operator of the Nicolai Creek Unit and all surrounding oil and gas leases
and owns 100% of the Unit working interests at these producing depths. The only affected lease
owners of this application is the State of Alaska, Department of Natural Resources (DNR), Mental
Health Trust, and Cook Inlet Region Incorporated (CM). The Notice required by AOGCC regulation
has been sent to the DNR, MHT, and CIRI, and an Affidavit attesting to this and the other facts
contained herein is attached. The other lessees, working interest owners, within 3000' of the affected
area are Apache, Buccaneer, ConocoPhillips, and Hilcorp.
Should questions arise in connection with this request, please contact me at the numbers below.
Respectfully Submitted RV,
