ERRATA NOTICE
The Alaska Oil and Gas Conservation Commission (AOGCC) notes that Conservation Order
477B (CO 477B) had two sections of the original affected area of Conservation Order 477A (CO
477A) omitted from the Affected Area table and that CO 477A did not reflect an Amendment
originally made to Conservation Order 477. Namely, sections 30 and 31 of Township/Range
14N-10E were omitted from “Table 1: Legal Description of the Expanded SBOP” of CO 477B,
and the sustained casing pressure rules defined by Conservation Order 496 (CO 496) were absent
from the Rules of CO 477A and hence those of CO 477B. These corrections will be reflected in a
Conservation Order 477B Errata to be issued by the AOGCC.

IT APPEARING THAT:
1.By application dated February 4, 2025, Hilcorp Alaska, LLC (Hilcorp), as operator of the
Milne Point Unit (MPU) and operator of the Nikaitchuq Unit (NU), requested an order
from the Alaska Oil and Gas Conservation Commission (AOGCC) to expand the affected
area of Conservation Order No. 477A (CO 477A), which established pool rules for the MPU
Schrader Bluff Oil Pool (SBOP), and to supersede Conservation Order No. 639 (CO 639),
which established pool rules for the NU Nikaitchuq Schrader Bluff Oil Pool (NSBOP).
2.Pursuant to 20 AAC 25.540, the AOGCC tentatively scheduled a public hearing for April 3,
2025, at 10:00 AM. On February 24, 2025, the AOGCC published notice of that hearing on
the State of Alaska’s Online Public Notice website and on the AOGCC’s website and
electronically transmitted the notice to all persons on the AOGCC’s email distribution list.
On February 26, 2025, the notice was also published in the Anchorage Daily News.
3.The AOGCC received no comments or requests to hold the proposed hearing. The tentatively
scheduled hearing was vacated.
4.Hilcorp’s application, AOGCC’s records, and publicly available information provide
sufficient information upon which to make an informed decision.
FINDINGS:
1.Order History
x CO 255, issued July 2, 1990, defined the SBOP and established Pool Rules to govern its
operations.
x CO 477, issued August 23, 2002, expanded the extent of the SBOP and consolidated
several older conservation orders into one comprehensive set of Pool Rules for the SBOP
in the MPU.
x CO 496, issued September 8, 2003, defined sustained casing pressure rules for
development wells in all pools within the Milne Point Field.
Conservation Order 477B Errata
September 18, 2025
Page 2 of 9
x CO 639, issued November 19, 2010, defined a new oil pool, the NSBOP, and prescribed
comprehensive Pool Pules governing operation of that pool.
x CO 806, issued July 11, 2023, granted an exception to well spacing requirements for well
MPU M-61in the SBOP.
2. CO 477A, issued May 29, 2024, expanded the aerial extent of the SBOP within the MPU.
Operatorship History of SBOP and NSBOP
The SBOP was defined in 1990 and operated initially by Conoco Inc. In 1994, BP
Exploration Alaska became sole owner and operator of the MPU and the SBOP. In 2020,
Hilcorp North Slope, LLC became sole owner and operator of the MPU and the SBOP. The
NSBOP was defined in 2010 and initially operated by Eni US Operating Company, Inc. In
2024, Hilcorp Alaska, LLC acquired the Nikaitchuq assets from Eni and became sole owner
and operator for the NU and the NSBOP.
3. Owners and Landowners
The affected landowner of the MPU and the NU is the State of Alaska, Department of
Natural Resources (DNR). All lands within the Affected Area are leased from the State of
Alaska. Hilcorp, Herbaly Exploration LLC, and George Alan Joyce are the lease holders of
the MPU. Hilcorp is the sole lease holder of the NU.
4. Expansion of the SBOP
Hilcorp proposes combining the SBOP and the NSBOP into one contiguous oil pool that
underlies part of the MPU and all the NU. This expanded SBOP will incorporate about
21,228.6 acres currently assigned to the NSBOP. Figure 1, below, presents a map depicting
the current and proposed Affected Areas. A legal description for the expanded Affected Area
is presented in Table 1, below.
5. Expansion Justification
To support this proposed pool expansion, Hilcorp provided confidential data to the AOGCC
consisting of a seismic cross-section, annotated with well logs, that passes through the NU
(west to east) and the MPU (northwest to southeast), and a structure map of the Schrader
Bluff OA Sand showing a continuous oil-water contact that crosses the MPU and NU
boundary. These data give Hilcorp high confidence that the Schrader Bluff forms a common
reservoir within both units. Hilcorp’s initial plan is to further develop the SBOP by drilling
wells from the Milne Point Raven Pad that cross the NU-MPU boundary. Figure 1 also
depicts the locations of several currently proposed wells to be drilled from the Milne Point
Raven Pad.
CONCLUSIONS:
1. AOGCC accepts Hilcorp’s request to keep the seismic data and OA Sand structure map
confidential because they are based on interpreted data.
2. Information provided by Hilcorp demonstrates that the SBOP is continuous across the MPU
and NU boundary and that combining the NSBOP and the MPU SBOP into one single,
contiguous pool is appropriate.

3. Having an administrative action rule in the SBOP pool rules is no longer necessary due to
AOGCC regulations now allowing administrative action to be taken on any order issued by
the AOGCC.
NOW, THEREFORE, IT IS ORDERED:
1. This conservation order hereby supersedes CO 477A, dated May 29, 2024, and all associated
administrative approvals to CO 477A (CO 477A.001, CO 477A.002, and CO 477A.003). The
record, findings, and conclusions of CO 477A and its associated administrative approvals are
incorporated by reference into the record for this order.
2. This conservation order hereby supersedes CO 806. The record, findings, and conclusions of
CO 806 are incorporated by reference into the record for this order.
3. This conservation order hereby supersedes CO 639, dated November 19, 2010, that defined
the NSBOP.
4. This conservation order hereby supersedes Administrative Approval CO 639.001 and
639.002.
5. The development and operation of the SBOP within the affected area is subject to the
following rules and the statewide requirements under 20 AAC 25 (to the extent not
superseded by these rules).

Rule 13: Sustained Casing Pressure Rules (Restated from CO 496)
a. The operator shall conduct and document a pressure test of tubulars and completion
equipment in each development well at the time of installation or replacement that is
sufficient to demonstrate that planned well operations will not result in failure of well
integrity, uncontrolled release of fluid or pressure, or threat to human safety.
b. The operator shall monitor each development well daily to check for sustained pressure,
except if prevented by extreme weather conditions, emergency situations, or similar
unavoidable circumstances. Monitoring results shall be made available for AOGCC
inspection.
c. The operator shall notify the AOGCC within three working days after the operator
identifies a well as having (1) sustained inner annulus pressure that exceeds 2000 psig or
(2) sustained outer annulus pressure that exceeds 1000 psig.
d. The AOGCC may require the operator to submit in an Application for Sundry Approvals
(Form 10-403) a proposal for corrective action or increased surveillance for any
development well having sustained pressure that exceeds a limit set out in paragraph “c”
of this rule. The AOGCC may approve the operator’s proposal or may require other
corrective action or surveillance. The AOGCC may require that corrective action be
verified by mechanical integrity testing or other AOGCC approved diagnostic tests. The
operator shall give AOGCC sufficient notice of the testing schedule to allow AOGCC to
witness the tests.
e. If the operator identifies sustained pressure in the inner annulus of a development well
that exceeds 45% of the burst pressure rating of the well’s production casing for inner
annulus pressure, or sustained pressure in the outer annulus that exceeds 45% of the burst
pressure rating of the well’s surface casing for outer annulus pressure, the operator shall
notify the AOGCC within three working days and take corrective action. Unless well
conditions require the operator to take emergency corrective action before AOGCC
approval can be obtained, the operator shall submit in an Application for Sundry
Approvals (Form 10-403) a proposal for corrective action. The AOGCC may approve the
operator’s proposal or may require other corrective action. The AOGCC may also require
that corrective action be verified by mechanical integrity testing or other AOGCC
approved diagnostic tests. The operator shall give AOGCC sufficient notice of the testing
schedule to allow AOGCC to witness the tests.
f. Except as otherwise approved by the AOGCC under paragraph “d” or “e” of these rules,
before a shut-in well is placed in service, any annulus pressure must be relieved to a
sufficient degree (1) that the inner annulus pressure at operating temperature will be
below 2000 psig and (2) that the outer annulus pressure at operating temperature will be
below 1000 psig. However, a well that is subject to paragraph “c” but not paragraph “e”
Conservation Order 477B Errata
September 18, 2025
Page 9 of 9
of these rules may reach an annulus pressure at operating temperature that is described in
the operator’s notification to the AOGCC under paragraph “c,” unless the AOGCC
prescribes a different limit.
g. For purposes of these rules,
“inner annulus” means the space in a well between tubing and production casing;
“outer annulus” means the space in a well between production casing and surface casing;
“sustained pressure” means pressure that (1) is measurable at the casing head of an
annulus, (2) is not caused solely by temperature fluctuations, and (3) is not pressure that
has been applied intentionally.

The SBOP was defined in 1990 and operated initially by Conoco Inc. In 1994, BP
Exploration Alaska became sole owner and operator of the MPU and the SBOP. In 2020,
Hilcorp North Slope, LLC became sole owner and operator of the MPU and the SBOP. The
NSBOP was defined in 2010 and initially operated by Eni US Operating Company, Inc. In
2024, Hilcorp Alaska, LLC acquired the Nikaitchuq assests from Eni and became sole owner
and operator for the NU and the NSBOP.
3. Owners and Landowners
The affected landowner of the MPU and the NU is the State of Alaska, Department of
Natural Resources (DNR). All lands within the Affected Area are leased from the State of
Alaska. Hilcorp, Herbaly Exploration LLC, and George Alan Joyce are the lease holders of
the MPU. Hilcorp is the sole lease holder of the NU.
4. Expansion of the SBOP
Hilcorp proposes combining the SBOP and the NSBOP into one contiguous oil pool that
underlies part of the MPU and all the NU. This expanded SBOP will incorporate about
21,228.6 acres currently assigned to the NSBOP. Figure 1, below, presents a map depicting
the current and proposed Affected Areas. A legal description for the expanded Affected Area
is presented in Table 1, below.
5. Expansion Justification
To support this proposed pool expansion, Hilcorp provided confidential data to the AOGCC
consisting of a seismic cross-section, annotated with well logs, that passes through the NU
(west to east) and the MPU (northwest to southeast), and a structure map of the Schrader
Bluff OA Sand showing a continuous oil-water contact that crosses the MPU and NU
boundary. Hilcorp has high confidence that this data suggests that the Schrader Bluff forms a
common reservoir that lies within both units. Hilcorp requested that the seismic data and OA
Sand map be held confidential. Hilcorp’s initial plan is to further develop the SBOP by
drilling wells from the Milne Point Raven Pad that cross into the NU. Figure 1 also depicts
the locations of several currently proposed wells to be drilled from the Milne Point Raven
Pad.
CONCLUSIONS:
1. AOGCC accepts Hilcorp’s request to keep the seismic data and OA Sand structure map
confidential because they are based on interpreted data.
2. Information provided by Hilcorp demonstrates that the SBOP is continuous across the MPU
and NU boundary and that combining the NSBOP and the MPU SBOP into one single,
contiguous pool is appropriate.
3. Having an administrative action rule in the SBOP pool rules is no longer necessary due to
AOGCC regulations now allowing administrative action to be taken on any order issued by
the AOGCC.

Re: Docket Number: CO-25-005
Spacing Exception Milne Point Unit H-21 Injector Well
Milne Point Unit
Schrader Bluff Oil Pool
Dear Ms. Wilson:
By letter dated March 3, 2025, Hilcorp Alaska, LLC (Hilcorp) requested the Alaska Oil and Gas
Conservation Commission (AOGCC) issue an order approving an exception to the spacing
requirements of Conservation Order 477A1 (CO 477A) to drill, complete, short-term pre-produce
(flow back for up to 60 days), and operate as a service injection well the proposed Milne Point
Unit (MPU) H-21 well (MPU H-21) within 500 feet of the external boundary of the Schrader Bluff
Oil Pool (SBOP) affected area, MPU, North Slope Borough, Alaska.
Pursuant to 20 AAC 25.540, AOGCC tentatively scheduled a public hearing for May 13, 2025.
On March 10, 2025, AOGCC published notice of the opportunity for that hearing on the State of
Alaska’s Online Public Notice website and on AOGCC’s website, electronically transmitted the
notice to all persons on AOGCC’s email distribution list. On March 12, 2025, AOGCC published
the notice in the Anchorage Daily News. Hilcorp sent, by certified mail, notice of the application
to all owners, landowners, and operators of all properties within 1,000 feet of the MPU H-21 well
trajectory and provided the notice, addresses to which the notices were delivered, and certified
mail receipts to AOGCC.
The AOGCC received no comments or requests to hold the proposed hearing. The scheduled
hearing was vacated. Hilcorp’s application, the hearing record, AOGCC’s records, and publicly
available information provide sufficient information upon which to make an informed decision.
1 As discussed below, since Hilcorp submitted this application, CO 477A has been superseded by CO 477B.
Accordingly, the AOGCC is treating Hilcorp’s application as a request for an exception to CO 477B.
CO 477B.001
July 28, 2025
Page 2 of 5
PURPOSE AND NEED FOR THIS ORDER
Well spacing regulations protect the oil and oil rights of adjacent landowners and maximize
resource recovery by establishing default limits on how close, under the land's surface, oil and gas
wells can be to each other and to property lines where ownership changes hands. These limits are
set forth in a regulation 20 AAC 25.055 or in pool rules like CO 477B. Operators must abide by
the default well spacing limits (referred to as statewide spacing requirements) unless they apply
for, and obtain, an exception to those limits. Although exceptions to the default well spacing
requirements are not unusual, AOGCC carefully evaluates each application, and typically grants
them only when actual geologic conditions demonstrate that the proposed subsurface location of a
well is necessary to reach otherwise unreachable oil or gas, the rights of both adjacent landowners
are upheld, and underground drinking water can be protected. As a general matter, AOGCC does
not have extensive authority over surface impacts such as noise, emissions, or construction.
FINDINGS
Hilcorp is operator for the MPU and the planned MPU H-21, an onshore, horizontal, extended-
reach injection well that targets the informally named OBa reservoir sandstone within the SBOP.
Surface Location: 2529' FNL, 1212’ FWL, Section 34, T13N, R10E, U.M.
Top Productive Horizon: 70’ FSL, 1320’ FWL, Section 34, T13N, R10E, U.M.
Bottom Hole Location: 70’ FSL, 1440’ FEL, Section 31, T13N, R10E, U.M.
MPU H-21 will be located on State of Alaska leases ADL 025906 and ADL 025517 that are
operated by Hilcorp. Adjacent immediately to the south are State of Alaska leases ADL 025627
and ADL 025628 that lie within the Kuparuk River Unit (KRU), which is operated by CPAI.
Since Hilcorp submitted this application, the AOGCC has issued CO 477B, which expands the
areal extent of the SBOP and restates the rules governing that pool. CO 477B supersedes CO 477A
and all administrative approvals associated with CO 477A. Accordingly, Rule 2 of CO 477B now
governs well spacing in the SBOP within the MPU. That Rule states: “There are no restrictions as
to well spacing except that no pay shall be opened in a well closer than 500 feet from the exterior
boundary of the affected area.”
At Milne Point, the SBOP development comprises three high permeability reservoir sandstones
(informally designated as OBa, OA, and NB, in ascending stratigraphic order). These sandstones
were deposited in shallow marine and fluvial-deltaic environments, are relatively uniform in
thickness, and are widespread throughout the MPU and adjacent acreage within the KRU.
MPU H-21 will be drilled to the west from a surface location on H-Pad. This well will open
reservoir along a course that lies parallel to, and 70 feet from, the external boundary of the SBOP,
which coincides with the boundary line separating the MPU from adjacent leases within the CPAI-
operated KRU. This horizontal, extended-reach well will open a two-and-one-half-mile long
section of Schrader Bluff OBa reservoir to injection.
MPU H-21 will be the peripheral well of a line-drive injection pattern. Fluid injected into this well
will push a uniform, linear bank of oil toward the planned, parallel, horizontal MPU H-22
CO 477B.001
July 28, 2025
Page 3 of 5
production well that will be located about 1,000 feet to the north. Similarly, injection into MPU
H-21 will also push a uniform, linear bank of oil toward the south into the KRU.
Figure 1. Map of Planned Hilcorp MPU H-21 Wellbore Displaying the Proposed Well Path
(Source: Modified from Hilcorp Alaska, LLC)
The courses of MPU H-21 and MPU H-22 are situated at the most prospective locations on the
subsurface structure and within the reservoir.
Polymer-injection pilot projects within the MPU SBOPconducted below reservoir parting pressure
greatly improved pattern sweep efficiency and increased ultimate recovery. Polymer injection also
significantly reduces direct channeling of injected water from injectors to producers, a problem
CO 477B.001
July 28, 2025
Page 4 of 5
that has adversely impacted past waterflood projects in Schrader Bluff reservoirs.2 Injection at
pressures less than reservoir fracturing pressure will safely maintain reservoir pressure and should
not adversely impact CPAI’s future development of adjacent Schrader Bluff reservoirs within the
KRU.
Polymer injection into MPU H-21 will impact oil reserves that lie within 500 feet of the external
boundary of the MPU SBOP. These reserves would not be swept by an injection well conforming
to the spacing requirements of CO 477B Rule 2. A horizontal production well located 500 feet
from the external boundary would recover only a small portion of these reserves.
Limited-duration pre-production of MPU H-21 (60 days or less) prior to injection operations will
clean out the well bore, improve injectivity, and recover a portion of the oil reserves from those
portions of Hilcorp’s leases that lie within 70’ of the MPU-KRU boundary. Such limited-duration
pre-production will not significantly impact oil reserves on adjacent CPAI acreage.
CONCLUSIONS
An exception to the well spacing provisions of CO 477B is necessary to allow drilling, completion,
limited-duration pre-production, and regular injection into the SBOP in MPU H-21 well to
maximize ultimate resource recovery.
It is not possible to recover a significant portion the targeted reserves from a well location that
conforms to the spacing requirements CO 477B.
Recent polymer-injection pilot projects within viscous-oil-bearing Schrader Bluff reservoirs at
MPU have demonstrated the effectiveness of polymer injection to improve pattern sweep
efficiency, increase expected ultimate recovery, and significantly reduce water channeling.
Injection of polymer at pressures no greater reservoir fracturing pressure will safely maintain
reservoir pressure and should not adversely impact CPAI’s future development of adjacent
Schrader Bluff reservoirs within the KRU.
Limiting pre-production of MPU H-21 to 60 days will increase injectivity and will not adversely
affect reserves located within the KRU.
If constructed and operated as required, granting an exception to the well spacing provisions of
CO 477B for MPU H-21 will not result in waste or jeopardize correlative rights of adjoining or
nearby owners, is based on sound engineering and geoscience principles, and will not result in an
increased risk of fluid movement into freshwater.

NOW THEREFORE IT IS ORDERED
The AOGCC grants Hilcorp’s March 3, 2025 application for an exception to the well spacing
provisions of CO 477B to allow drilling, completion, limited-duration pre-production, and
injection into well MPU H-21 within the SBOP. Hilcorp may proceed and must comply with the
constraints stated below, all applicable laws, and all other legal requirements.
1. Constraints requested to apply until December 31, 2030:
a. Injection pressure gradients not to exceed 0.65 psi/ft;
b. No gas injection;
c. Pre-production of MPU H-31 not to exceed 60 days; and
d. Downhole pressure gauge data for the Well provided to CPAI upon written request,
or as reasonably necessary.
2. Constraint requested to apply for the life of the well:
a. Injection only (cannot be converted to a producer).

Re: Docket Number: CO-25-006
Application for Spacing Exception Milne Point Unit H-31 Extended Well (Injector)
Amendment to CO 477.009
Milne Point Unit
Schrader Bluff Oil Pool
Dear Ms. Wilson:
By letter dated March 3, 2025, Hilcorp Alaska, LLC (Hilcorp) requested the Alaska Oil and Gas
Conservation Commission (AOGCC) amend an existing spacing exception order (CO 477.009)
that approved an exception to the spacing requirements of Conservation Order 477 (CO 477) to
drill, complete, test, pre-produce for a limited period (up to 60 days), and operate as a service
injection well the proposed Milne Point Unit (MPU) H-31 well (MPU H-31) within 500 feet of the
external boundary of the Schrader Bluff Oil Pool (SBOP) affected area, MPU, North Slope
Borough, Alaska. Hilcorp seeks to amend the spacing exception approved in CO 477.009 as the
planned well course for MPU H-31 has since changed.
Pursuant to 20 AAC 25.540, AOGCC tentatively scheduled a public hearing for May 13, 2025.
On March 10, 2025, AOGCC published notice of the opportunity for that hearing on the State of
Alaska’s Online Public Notice website and on AOGCC’s website, electronically transmitted the
notice to all persons on AOGCC’s email distribution list. On March 12, 2025, AOGCC published
the notice in the Anchorage Daily News. Hilcorp sent, by certified mail, notice of the application
to all owners, landowners, and operators of all properties within 1,000 feet of the MPU H-31 well
trajectory and provided the notice, addresses to which the notices were delivered, and certified
mail receipts to AOGCC.
The AOGCC received no comments or requests to hold the proposed hearing. The scheduled
hearing was vacated. Hilcorp’s application, the hearing record, AOGCC’s records, and publicly
available information provide sufficient information upon which to make an informed decision.
CO 477B.002
July 28, 2025

PURPOSE AND NEED FOR THIS ORDER
Well spacing regulations protect the oil and oil rights of adjacent landowners and maximize
resource recovery by establishing default limits on how close, under the land's surface, oil and gas
wells can be to each other and to property lines where ownership changes hands. These limits are
set forth in a regulation 20 AAC 25.055 or in pool rules like CO 477B. Operators must abide by
the default well spacing limits (referred to as statewide spacing requirements) unless they apply
for, and obtain, an exception to those limits. Although exceptions to the default well spacing
requirements are not unusual, AOGCC carefully evaluates each application, and typically grants
them only when actual geologic conditions demonstrate that the proposed subsurface location of a
well is necessary to reach otherwise unreachable oil or gas, the rights of both adjacent landowners
are upheld, and underground drinking water can be protected. As a general matter, AOGCC does
not have extensive authority over surface impacts such as noise, emissions, or construction.
FINDINGS
Hilcorp is operator for the MPU and the planned MPU H-31, an onshore, horizontal, extended-
reach injection well that targets the informally named OBa reservoir sandstone within the SBOP.
Surface Location: 2223' FNL, 1293’ FWL, Section 34, T13N, R10E, U.M.
Top Productive Horizon: 70’ FSL, 682’ FEL, Section 34, T13N, R10E, U.M.
Bottom Hole Location: 70’ FSL, 570’ FWL, Section 31, T13N, R10E, U.M.
Hilcorp’s amended application extends the course of proposed well MPU H-31 within the OA
reservoir, and it adds a final three-quarters of a mile section through the underlying OBa reservoir.
MPU H-31 will be located on State of Alaska leases ADL 025906 and ADL 025517 that are
operated by Hilcorp. Adjacent immediately to the south are State of Alaska leases ADL 025627
and ADL 025628 that lie within the Kuparuk River Unit (KRU), which is operated by CPAI.
Since Hilcorp submitted this application, the AOGCC has issued CO 477B, which expands the
areal extent of the SBOP and restates the rules governing that pool. CO 477B supersedes CO 477A
and all administrative approvals associated with CO 477A. Accordingly, Rule 2 of CO 477B now
governs well spacing in the SBOP within the MPU. That Rule states: “There are no restrictions as
to well spacing except that no pay shall be opened in a well closer than 500 feet from the exterior
boundary of the affected area.”
At Milne Point, the SBOP development comprises three high permeability reservoir sandstones
(informally designated as OBa, OA, and NB, in ascending stratigraphic order). These sandstones
were deposited in shallow marine and fluvial-deltaic environments, are relatively uniform in
thickness, and are widespread throughout the MPU and adjacent acreage within the KRU.
MPU H-31 will be drilled to the west from a surface location on H-Pad. This well will open
reservoir along a course that lies parallel to, and 70 feet from, the external boundary of the SBOP,
which coincides with the boundary line separating the MPU from adjacent leases within the CPAI-
operated KRU. The initial portion of this horizontal, extended-reach well will open a two-and-one-
CO 477B.002

Page 3 of 5
half-mile long section of Schrader Bluff OA reservoir to injection.The final portion of this well
will open about three-quarters of a mile of the underlying OBa reservoir to injection.
Figure 1. Map of Planned Hilcorp MPU H-31 Wellbore Displaying the Proposed Well Path
(Source: Modified from Hilcorp Alaska, LLC)
MPU H-31 will be the peripheral well of a line-drive injection pattern. Fluid injected into this well
will push a uniform, linear bank of oil toward the planned, parallel, horizontal MPU H-32
production well that will be located about 1,000 feet to the north. Similarly, injection into MPU
H-31 will also push a uniform, linear bank of oil toward the south into the KRU.
The courses of MPU H-31 and MPU H-32 are situated at the most prospective locations on the
subsurface structure and within the reservoirs.
CO 477B.002
July 28, 2025
Page 4 of 5
Polymer-injection pilot projects within the MPU SBOP conducted below reservoir parting pressure
greatly improved pattern sweep efficiency and increased ultimate recovery. Polymer injection also
significantly reduces direct channeling of injected water from injectors to producers, a problem
that has adversely impacted past waterflood projects in Schrader Bluff reservoirs.1 Injection at
pressures less than reservoir fracturing pressure will safely maintain reservoir pressure and should
not adversely impact CPAI’s future development of adjacent Schrader Bluff reservoirs within the
KRU.
Polymer injection into MPU H-31 will impact oil reserves that lie within 500 feet of the external
boundary of the MPU SBOP. These reserves would not be swept by an injection well conforming
to the spacing requirements of CO 477B Rule 2. A horizontal production well located 500 feet
from the external boundary would recover only a small portion of these reserves.
Limited-duration pre-production of MPU H-31 (60 days or less) prior to injection operations will
clean out the well bore, improve injectivity, and recover a portion of the oil reserves from those
portions of Hilcorp’s leases that lie within 70’ of the MPU-KRU boundary. Such limited-duration
pre-production will not significantly impact oil reserves on adjacent CPAI acreage.
CONCLUSIONS
An exception to the well spacing provisions of CO 477B is necessary to allow drilling, completion,
limited-duration pre-production, and regular injection into the SBOP in MPU H-31 well to
maximize ultimate resource recovery.
It is not possible to recover a significant portion the targeted reserves from a well location that
conforms to the spacing requirements CO 477B.
Recent polymer-injection pilot projects within viscous-oil-bearing Schrader Bluff reservoirs at
MPU have demonstrated the effectiveness of polymer injection to improve pattern sweep
efficiency, increase expected ultimate recovery, and significantly reduce water channeling.
Injection of polymer at pressures no greater reservoir fracturing pressure will safely maintain
reservoir pressure and should not adversely impact CPAI’s future development of adjacent
Schrader Bluff reservoirs within the KRU.
Limiting pre-production of MPU H-31 to 60 days will increase injectivity and will not adversely
affect reserves located within the KRU.
If constructed and operated as required, granting an exception to the well spacing provisions of
CO 477B for MPU H-31 will not result in waste or jeopardize correlative rights of adjoining or
nearby owners, is based on sound engineering and geoscience principles, and will not result in an
increased risk of fluid movement into freshwater.

Dear Ms. Wilson:
By letter dated March 3, 2025, Hilcorp Alaska, LLC (Hilcorp) requested the Alaska Oil and Gas
Conservation Commission (AOGCC) issue an order approving an exception to the spacing
requirements of Conservation Order 477A1 (CO 477A) to drill, complete, short-term pre-produce
(flow back for up to 60 days), and operate as service injection wells the proposed Milne Point Unit
(MPU) H-41 and H-43 wells (MPU H-41 and MPU H-43) within 500 feet of the external boundary
of the Schrader Bluff Oil Pool (SBOP) affected area, MPU, North Slope Borough, Alaska.
Pursuant to 20 AAC 25.540, AOGCC tentatively scheduled a public hearing for May 13, 2025.

The AOGCC received no comments or requests to hold the proposed hearing. The scheduled
hearing was vacated. Hilcorp’s application, the hearing record, AOGCC’s records, and publicly
available information provide sufficient information upon which to make an informed decision.
1 As discussed below, since Hilcorp submitted this application, CO 477A has been superseded by CO 477B.
Accordingly, the AOGCC is treating Hilcorp’s application as a request for an exception to CO 477B.

FINDINGS
Hilcorp is operator for the MPU and the planned MPU H-41 and MPU H-43, onshore, horizontal,
extended-reach injection wells.
MPU H-41 targets the informally named NB and OA reservoir sandstones within the SBOP.
Surface Location: 2435' FNL, 1105’ FWL, Section 34, T13N, R10E, U.M.
Top Productive Horizon: 70’ FSL, 2535’ FWL, Section 33, T13N, R10E, U.M.
Bottom Hole Location: 70’ FSL, 70’ FWL, Section 31, T13N, R10E, U.M.
MPU H-43 targets the NB and OA reservoir sandstones within the SBOP.
Surface Location: 2291' FNL, 1158’ FWL, Section 34, T13N, R10E, U.M.
Top Productive Horizon: 1497’ FSL, 612’ FWL, Section 33, T13N, R10E, U.M.
Bottom Hole Location: 2004’ FSL, 70’ FWL, Section 31, T13N, R10E, U.M.
MPU H-41 and MPU H-43 will be located on State of Alaska leases ADL 025906 and ADL
025517 that are operated by Hilcorp. Adjacent immediately to the south are State of Alaska leases
ADL 025627 and ADL 025628 that lie within the Kuparuk River Unit (KRU), which is operated
by ConocoPhillips Alaska Inc. (CPAI). Immediately adjacent to the west is State of Alaska lease
ADL 025519 that also lies within the KRU.
Since Hilcorp submitted this application, the AOGCC has issued CO 477B, which expands the

At Milne Point, the SBOP development comprises three high permeability reservoir sandstones
(informally designated as OBa, OA, and NB, in ascending stratigraphic order). These sandstones

were deposited in shallow marine and fluvial-deltaic environments, are relatively uniform in
thickness, and are widespread throughout the MPU and adjacent acreage within the KRU.

MPU H-41 will be drilled to the west from a surface location on H-Pad. This well will open
reservoir along a course that lies parallel to, and 70 feet from, the external boundary of the SBOP,
which coincides with the boundary line separating the MPU from adjacent leases within the CPAI-
operated KRU. The initial portion of this horizontal, extended-reach well will open a one-and-

three-quarters-mile long section of Schrader Bluff NB reservoir to injection. The final portion of
the well will open a nearly one-mile long section of Schrader Bluff OA reservoir to injection.
MPU H-41 will be the peripheral well of a line-drive injection pattern. Fluid injected into this well
will push a uniform, linear bank of oil toward the planned, parallel, horizontal MPU H-42
production well that will be located about 800’ to 1,000 feet to the north. Similarly, injection into
MPU H-41 will also push a uniform, linear bank of oil toward the south into the KRU.
MPU H-43 will be drilled to the west from a surface location on H-Pad. This well will open about
one-and-one-half miles of NB reservoir along a west-trending course that mainly lies
approximately parallel to, and about 1,500’ and 2,000’ feet north of, MPU H-41. The final portion
of the well will open about three-quarters of a mile long section of Schrader Bluff OA reservoir to
injection. MPU H-43 will lie about 800’ to 1,000’ north of the planned parallel, MPU H-42
producer that will lie in between, and approximately equidistant from, MPU H-41 and MPU H-43.
An exception to the spacing requirements is needed for MPU H-43 because the proposed bottom-
hole location lies 70’ from State of Alaska Lease ADL 025519, which lies to the west within the
CPAI-operated KRU. MPU H-43 will push a linear bank of oil toward the H-42 producer. The
lowermost portion of MPU H-43 will also push oil west into the KRU.
The courses of MPU H-41 and MPU H-43 and MPU H-42 are situated at the most prospective
locations on the subsurface structure and within the reservoirs.
Polymer-injection pilot projects within the MPU SBOP conducted below reservoir parting pressure
greatly improved pattern sweep efficiency and increased ultimate recovery. Polymer injection also
significantly reduces direct channeling of injected water from injectors to producers, a problem
that has adversely impacted past waterflood projects in Schrader Bluff reservoirs.2 Injection at

Polymer injection into MPU H-41 and MPU H-43 will impact oil reserves that lie within 500 feet
of the external boundary of the MPU SBOP. These reserves would not be swept by an injection
well conforming to the spacing requirements of CO 477B Rule 2.
Limited-duration pre-production of MPU H-41 and MPU H-43 (60 days or less) prior to injection
operations will clean out the well bore, improve injectivity, and recover a portion of the oil reserves
from those portions of Hilcorp’s leases that lie within 70’ of the MPU-KRU boundary. Such
limited-duration pre-production will not significantly impact oil reserves on adjacent CPAI
acreage.

Re: Docket Number: CO-25-013
Application for Spacing Exception Milne Point Unit M-65 Injector Well
Schrader Bluff Oil Pool
Milne Point Unit
North Slope Borough, Alaska
Dear Ms. Wilson:
By letter received June 23, 2025, Hilcorp Alaska, LLC (Hilcorp) requested the Alaska Oil and Gas
Conservation Commission (AOGCC) issue an order approving an exception to the spacing
requirements of Conservation Order 477B (CO 477B) to drill, complete, short-term pre-produce
(flow back for up to 30 days1), and operate as service injection well the proposed Milne Point Unit
(MPU) M-65 well (MPU M-65) within 500 feet of the external boundary of the Schrader Bluff Oil
Pool (SBOP) affected area, MPU, North Slope Borough, Alaska.
Pursuant to 20 AAC 25.540, AOGCC tentatively scheduled a public hearing for August 7, 2025.
On June 26, 2025, AOGCC published notice of the opportunity for that hearing on the State of
Alaska’s Online Public Notice website and on AOGCC’s website and electronically transmitted
the notice to all persons on AOGCC’s email distribution list. On June 29, 2025, AOGCC published
the notice in the ANCHORAGE DAILY NEWS.
In accordance with 20 AAC 25.055(d), Hilcorp sent, by certified mail, notice of the application to
all owners, landowners, and operators of all properties within 1,000 feet of the MPU M-65 well
and provided to AOGCC copies of the notices and addresses to which the notices were delivered.
1 Hilcorp’s application states on page 2: “Hilcorp intends to flow back this well for up to 30 days to fully clean out the
wellbore to reduce the effect of near-wellbore damage caused by drilling fluid invasion which will ensure maximum
injectivity”, and “Associated oil will only be “produced” for 30 days to ensure the wellbore is as clean as possible
before commencing injection operations.” In combination, these statements are a bit unclear; however, adjacent lease
owner/operator ConocoPhillips Alaska, Inc. subsequently proposed, and Hilcorp concurred with, pre-production not
to exceed 60 days. See emails referenced in footnotes 3 and 4, below. Pre-production for up to 60 days also conforms
to durations approved in similar SBOP spacing exception orders CO 477B.001, CO 477B.002, and CO 477B.003.
CO 477B.004
December 9, 2025
Page 2 of 6
The AOGCC received one comment from an adjacent owner / operator requesting the proposed
hearing be held if Hilcorp and that operator were unable to reach an acceptable agreement.
Subsequently, that requestor reported an acceptable agreement had been reached, Hilcorp
concurred that an agreement had been reached, and the scheduled hearing was vacated.
Hilcorp’s application, additional information submitted by Hilcorp and the adjacent operator,
AOGCC’s records, and publicly available information are sufficient to make an informed decision.
PURPOSE AND NEED FOR THIS ORDER
Well spacing regulations protect the oil and oil rights of adjacent landowners and maximize
resource recovery by establishing default limits on how close, under the land's surface, oil and gas
wells can be to each other and to property lines where ownership changes hands. These limits are
set forth in a regulation 20 AAC 25.055 or in pool rules like CO 477B. Operators must abide by
the default well spacing limits (referred to as spacing requirements) unless they apply for, and
obtain, an exception to those limits. Although exceptions to the default well spacing requirements
are not unusual, AOGCC carefully evaluates each application, and typically grants them only when
actual geologic conditions demonstrate that the proposed subsurface location of a well is necessary
to reach otherwise unreachable oil or gas, the rights of both adjacent landowners are upheld, and
underground drinking water can be protected. As a general matter, AOGCC does not have
extensive authority over surface impacts such as noise, emissions, or construction.
FINDINGS
MPU M-65 will be located as follows.
Surface: 363' FNL, 741' FEL, Section 14, T13N, R9E, Umiat Meridian (UM)
Target (Estimated): 558' FNL, 137’ FWL, Section 14, T13N, R9E, UM
Bottom Hole: 116' FSL, 94’ FWL, Section 23, T13N, R9E, UM
Hilcorp is operator for the MPU and for this proposed onshore, extended-reach, horizontal
injection well that will lie parallel to, and within 500 feet of, the external boundary of the SBOP,
which in this area also separates the MPU from the Kuparuk River Unit (KRU). (See Figure 1,
below.) CPAI is operator for adjacent KRU leases ADL 355023, ADL 25513, ADL 25519, and
ADL 25520.
The affected landowner is the State of Alaska (SOA). Hilcorp is 100% working interest owner for
lease ADL 025514, which contains the proposed surface, target, and bottom-hole locations for
MPU-65. On Figure 1, the horizontal portion of MPU M-65 that will be open to the SBOP is
depicted by the north-south oriented red line.
A portion of the MPU-65 wellbore that is shallower than the target reservoir interval will traverse
part of adjacent lease ADL 355023 that lies within the KRU and is owned by ConocoPhillips
Alaska, Inc. (CPAI) and ExxonMobil Alaska Production Inc. (ExxonMobil). Authorization to drill
this portion of the well has been granted by the Alaska Department of Natural Resources (DNR)
through a subsurface easement that is described in DNR’s Land Administration System Case File
CO 477B.004
December 9, 2025
Page 3 of 6
No. 421155, and is extended until June 12, 2029 by letter dated June 11, 2024.
2 The three
additional adjacent leases ADL 25513, ADL 25519, and ADL 25520 lie within the KRU and are
owned by CPAI and ExxonMobil.

Rule 2 of CO 477B governs well spacing for the SBOP within the MPU. An exception is required
for MPU M-65 because the proposed injection interval will lie within 500 feet of property lines
where ownership changes.

At Milne Point, the SBOP development comprises several high-permeability reservoir sandstones.
These sandstones were deposited in shallow marine and fluvial-deltaic environments, are relatively
uniform in thickness, and are widespread throughout the MPU and adjacent acreage in the KRU.
MPU M-65 will be drilled to the west-northwest from a surface location on M-Pad and then turned
directly south. This well will open to injection a nearly two-mile long section of reservoir along a
course that lies parallel to, and about 100 to 200 feet from, the external boundary of the SBOP,
which in this area coincides with the boundary line separating the MPU from adjacent leases within
the CPAI-operated KRU. The course of MPU M-65 is situated at the most prospective location on
the subsurface structure and within the Schrader Bluff reservoirs.
MPU M-65 will be the peripheral well of a line-drive injection pattern. Fluid and polymer injected
into this well will push a uniform, linear bank of oil toward a parallel, horizontal MPU production
well that will be located about 500 to 1,000 feet to the east. Similarly, injection into MPU M-65
will also push a uniform, linear bank of oil toward the west into the KRU. These reserves would
not be swept by an injection well conforming to the spacing requirements of CO 477B Rule 2.
Limited-duration pre-production of MPU M-65 (60 days or less) prior to injection operations will
clean out the well bore, improve injectivity, and recover a portion of the oil reserves from those
portions of Hilcorp’s leases that lie near the MPU-KRU boundary. Such limited-duration pre-
production will not significantly impact oil reserves on adjacent CPAI acreage.
CPAI, owner and operator of the four adjacent leases, has agreed to drilling and operation of MPU
M-65 as an injection well contingent upon the conditions listed below.3 By email dated July 30,
2025, Hilcorp concurred with these conditions.4
x Injection pressure gradients not to exceed 0.65 psi/ft;
x No gas injection;
x Pre-production of the well not to exceed 60 days;
x Downhole pressure gauge data for the well will be provided to CPAI upon written
request, or as reasonably necessary;
x Injection only (cannot be converted to a producer); and
x Hilcorp will not penetrate the N-sand interval, as seen at 3,552’ MD in the West Sak
No. 1 well, on ADL 355023.
If conducted as required, drilling, completion, pre-production, and operation of MPU M-65 as an
injection well will not cause waste or result in an increased risk of fluid movement into freshwater.

CONCLUSIONS
An exception to the well spacing provisions of CO 477B is necessary to allow drilling, completion,
limited-duration pre-production, and regular injection into the SBOP in MPU M-65 well to
maximize ultimate resource recovery.
It is not possible to recover a significant portion of the targeted reserves from well locations that
conform to the spacing requirements CO 477B.
Limiting pre-production of MPU M-65 to 60 days will increase injectivity and will not adversely
affect reserves located within the KRU.
Correlative rights of landowners of leases adjacent to MPU M-65 will be protected by the
constraints specified below.
If constructed and operated as required, granting an exception to the well spacing provisions of
CO 477B for MPU M-65 will not result in waste or jeopardize correlative rights of adjoining or
nearby owners, is based on sound engineering and geoscience principles, and will not result in an
increased risk of fluid movement into freshwater.
NOW THEREFORE IT IS ORDERED
The AOGCC grants Hilcorp’s June 23, 2025, application for an exception to the well spacing
provisions of CO 477B to allow drilling, completion, limited-duration pre-production, and
injection into well MPU M-65 within the SBOP. Hilcorp may proceed and must comply with the
constraints stated below, all applicable laws, and all other legal requirements.
x Injection pressure gradients not to exceed 0.65 psi/ft;
x No gas injection;
x Pre-production of MPU M-65 not to exceed 60 days;
x Downhole pressure gauge data for the well will be provided to CPAI upon written
request, or as reasonably necessary;
x MPU M-65 is restricted to injection only and cannot be converted to a producer; and
x MPU M-65 will not penetrate the Schrader Bluff N-sand interval, as seen at 3,552’
MD in the West Sak No. 1 well, on lease ADL 355023.

Subject: [EXTERNAL] MPU M-65 Spacing Exception - Question
Hello Jamie,
I'm working on Hilcorp's requested spacing exception for the MPU M-65 well. A shallow portion of this well will be
drilled outside of the MPU, crossing a lease within the Kuparuk River Unit. Hilcorp's application states in part:
DNR's LAS Case File ADL 421155 contains the following:
According to this Case File, the DNR's interim authorization for Hilcorp's subsurface easement expired in June 2024.
Is this correct? If not, could Hilcorp please provide me with evidence of current authorization?
Thanks and Be Well,

Re: ADL 421155 Extension of Moose Pad Wellbore Easement Pursuant to AS 38.05.850
Dear Ms. Wilson:
On Tuesday May 28, 2024, Hilcorp Alaska, LLC (HAK) submitted a request to the State of Alaska,
Department of Natural Resources (DNR), Division of Oil and Gas (Division) to extend the entry authorization
for ADL 421155 in the North Slope region. The easement covers wellbores that originate in the Milne Point
Unit (MPU), pass through land located outside of the MPU, and return to lands located within the MPU. The
term of the easement is June 11, 2019, to June 11, 2054, conditioned upon meeting the terms of the entry
authorization. The entry authorization was issued on June 12, 2019, and expires June 12, 2024. The total area
of the easement is 240 acres.
The Division finds that an extension of the existing entry authorization is necessary, to allow time for
completion of the wellbores and a final survey to be provided to the Division. This extension will ensure the
authorization remains effective until the Division has all the information required to evaluate the survey, and
to complete the necessary administrative actions and process associated with a final easement.
This extension constitutes a minor change to the existing entry authorization and does not expand the scope,
nor does it constitute a new or expanded interest in state land. The entry authorization for this project is
hereby extended until the issuance of a final easement, or for a period of up to five (5) years expiring June 12,
2029, whichever occurs first. The easement remains subject to the terms and conditions defined in the entry
authorization granted on June 12, 2019. A final easement agreement for the wellbores will be issued upon
completion of the necessary administrative and public processes for easement authorizations pmsuant to AS
38.05.850.
If you have questions regarding this authorization, please contact Alexander Zinck at (907) 269-8804 or
alexander.zinck@alaska.gov.

Good afternoon, Samantha,
We have agreed to the following conditions with Hilcorp that we would like the AOGCC to
include in the order:
Injection pressure gradients not to exceed 0.65 psi/ft;
No gas injection;
Pre-production of the Well not to exceed 60 days; and
Downhole pressure gauge data for the Well provided to CPAI upon written request, or as
reasonably necessary.
Injection only (cannot be converted to a producer).
Hilcorp will not penetrate the N-sand interval, as seen at 3,552’ MD in the West Sak No.
1 well, on ADL 355023.
Hilcorp’s plans to backbuild its MPU M-65 into CPAI’s ADL 355023 under their Wellbore
Easement with the DNR will impair CPAI’s ability to fully develop its leasehold unless Hilcorp
stays out of the N-sand as laid out above.
Respectfully,
Ryan

Milne Point H-41 and H-43 Spacing Exception_3.3.25_eSIG.pdf
Steve,
I think I misunderstood what you were asking. The Exhibit A-1 on our application includes details to
the sands we are targeting in the Schrader Bluff for each well (application re-attached for reference).
However, we just realized that the H-43 is missing language stating the “Toe of the well will be
completed in the Schrader Oa”. The H-43 is planned to be drilled similarly to H-41 with the first 2/3
in the Schrader Nb and the last 1/3 in the Schrader Oa. Would we be able to set up a call to discuss
how to handle this clarification on our application? We don’t have plans to drill either of these wells
until Q1-2026.
Here is what it should say on Exhibit A-1 for the H-41 and H-43:
Thanks,
Jamie

Subject: RE: [EXTERNAL] Spacing Exception Application for MPU H-41 and MPU H-43 - Question
Steve,
We are only seeking Spacing Exception approval on the MPU H-41 and 43 injectors which will be
flowing back from the Schrader Bluff formation for up to 60 days. We made reference to the MPU H-
42 producer on the application just so you are aware we will be drilling a producer in between both
injectors. However, the MPU H-42 producer is not part of our application requesting spacing
exception approval since it is greater than 500’ from the unit boundary. Let me know if this answers
your question.
I do want to note that the first well in this batch of spacing exception requests to be drilled is the
MPU H-21 beginning as soon as the end of this month (Taylor – please correct me if this timeline has
moved up), so we ask that this well take precedent over the other applications. The next well to be
drilled is the H-31 which we are requesting an extension to the previously approved spacing
exception.
Thanks,
Jamie

Katie, Jamie:
I’m reviewing Hilcorp’s spacing exception application for these wells. To make certain my
understanding is correct, which Schrader Bluff reservoir sands will be opened by the planned
MPU H-43 injector and the associated MPU H-42 producer?

ALASKA OIL AND GAS CONSERVATION COMMISSION
RE: Docket Number: CO-25-013
Hilcorp Alaska, LLC’s Spacing Exception Application for Well MPU M-65
Milne Point Unit, North Slope Borough, Alaska
Hilcorp Alaska, LLC (Hilcorp), by letter dated June 23, 2025, filed an application with the Alaska
Oil and Gas Conservation Commission (AOGCC) for an exception to the spacing requirements of
20 AAC 25.055 and Rule 2 of Conservation Order No. 477B to drill, complete, short-term pre-
produce (flow back for up to 30 days), and inject into the Milne Point Unit M-65 service well in
the Schrader Bluff Oil Pool within 500 feet of the exterior boundary of the Schrader Bluff Oil Pool
Affected Area, pursuant to 20 AAC 25.055(d).
Surface Location: 363' FNL, 741' FEL, Section 14, T13N, R9E, Umiat Meridian (UM)
Target Location (Estimated): 558' FNL, 137’ FWL, Section 14, T13N, R9E, UM
Bottom Hole Location: 116' FSL, 94’ FWL, Section 23, T13N, R9E, UM
Well spacing regulations protect the oil and gas rights of adjacent leaseholders and landowners
and maximize resource recovery by establishing default limits on how close, under the land's
surface, oil and gas wells can be to property lines where ownership changes hands. These limits
are set forth in a regulation, 20 AAC 25.055. Operators must abide by the default limits unless
they apply for, and obtain, an order approving an exception to those limits. Although exceptions
to the default limits are not unusual, AOGCC carefully evaluates each application, and typically
grants them only when actual geologic conditions demonstrate that the proposed subsurface
location of a well is necessary to reach otherwise unreachable oil or gas and that both the rights of
adjacent leaseholders and landowners and underground drinking water can be protected. As a
general matter, AOGCC does not have extensive authority over surface impacts such as noise,
emissions, or construction.
This notice does not contain all the information filed by Hilcorp. To obtain more information,
contact the AOGCC’s Special Assistant, Samantha Coldiron, at (907) 793-1223 or
samantha.coldiron@alaska.gov.

a.m. via Microsoft Teams. The hearing, which may be changed to full virtual, if necessary, will be
held in the AOGCC hearing room located at 333 West 7th Avenue, Anchorage, AK 99501. The
audio call in information is (907) 202 7104 Conference ID: 876 411 274#. Anyone who wishes to
participate remotely using MS Teams video conference should contact Ms. Samantha Coldiron at
least two business days before the scheduled public hearing to request an invitation for the MS
Teams. To request that the tentatively scheduled hearing be held, a written request must be filed
with the AOGCC no later than 4:30 p.m. on July 15, 2025.

Spacing Exception
Milne Point Unit M-65 Well
June 18, 2025
Page 2 of 6
The M-65 Well will be an injection well. In order to achieve maximum injectivity of the
wellbore, Hilcorp intends to flow back this well for up to 30 days to fully clean out the
wellbore to reduce the effect of near-wellbore damage caused by drilling fluid invasion
which will ensure maximum injectivity. The initial flowback will consist mostly of drilling
and completion fluids, including cuttings and other fine materials that will be flowed to
tanks, transported offsite and disposed of in accordance with State regulations. Once the
flowback has less than 0.5% solids, the flow stream will be sent to the Milne Point
production facility to continue cleaning up. In order to prevent waste, Hilcorp intends to
sell any oil processed and separated at the production facility.
Hilcorp is not proposing to drill and complete this well as a producing oil well. Associated
oil will only be “produced” for 30 days to ensure the wellbore is as clean as possible before
commencing injection operations. The intent of this application is to allow Hilcorp to
prevent waste that may occur as a result of its cleanup process by:
1. Ensuring a clean wellbore to achieve maximum injectivity.
2. Enhancing recovery of the offset production well which will be spaced between
each injection well.
3. Avoid disposal of sales quality oil.
Additionally, well spacing within the Schrader Bluff Oil Pool is governed by Rule 2 of
Conservation Order 477b:
Rule 2. Well Spacing (Revised by CO 477.005, CO 477A.001, CO 477A.002, CO
477A.003, CO 477A.009, CO 806)
There are no restrictions as to well spacing except that no pay shall be opened in a well
closer than 500 feet from the exterior boundary of the affected area.
The proposed M-65 Well operations target undrained reserves that cannot be reached by
wells conforming to applicable spacing restrictions. Approval of short-term pre-production
of the proposed M-65 Well allows for protection of its correlative rights by recovering the
otherwise stranded reserves and ensures future maximum injectivity of the wellbore.
Additionally, the correlative rights of all affected owners, landowners and operators will
be protected and enhanced by the long-term support provided by the polymer injection.
Hilcorp anticipates drilling operations of the M-65 Well to commence as soon as January
2026.
This well is subject to Wellbore Easement ADL 421155 whereby the Alaska Department
of Natural Resources, Division of Oil and Gas, granted Hilcorp approval to traverse
through the Kuparuk River Unit. There will be no open casing from within the Kuparuk
River Unit.

Notice of Public Hearing
STATE OF ALASKA
ALASKA OIL AND GAS CONSERVATION COMMISSION
RE: Docket Number: CO-25-007
Hilcorp Alaska, LLC’s Spacing Exception Application for Wells MPU H-41 and H-43
Milne Point Unit, North Slope Borough, Alaska
Hilcorp Alaska, LLC (Hilcorp), by letter dated March 3, 2025, filed an application with the Alaska
Oil and Gas Conservation Commission (AOGCC) for an exception to the spacing requirements of
20 AAC 25.055 and Rule 2 of Conservation Order No. 477A to drill, complete, short-term pre-
produce (flow back for up to 60 days), and inject into the Milne Point Unit H-41 and H-43 service
wells in the Schrader Bluff Oil Pool within 500 feet of the exterior boundary of the Schrader Bluff
Oil Pool Affected Area, pursuant to 20 AAC 25.055(d).
MPU H-41
Surface Location: 2,435' FNL, 1,105' FWL, Section 34, T13N, R10E, Umiat Meridian (UM)
Target Location: 70' FSL, 2,535’ FWL, Section 33, T13N, R10E, UM
Bottom Hole Location: 70' FSL, 70’ FWL, Section 31, T13N, R10E, UM
MPU H-43
Surface Location: 2,291' FNL, 1,158' FWL, Section 34, T13N, R10E, UM
Target Location: 1,497' FSL, 612’ FWL, Section 33, T13N, R10E, UM
Bottom Hole Location: 2,004' FSL, 70’ FWL, Section 31, T13N, R10E, UM
Well spacing regulations protect the oil and gas rights of adjacent leaseholders and landowners
and maximize resource recovery by establishing default limits on how close, under the land's
surface, oil and gas wells can be to property lines where ownership changes hands. These limits
are set forth in a regulation, 20 AAC 25.055. Operators must abide by the default limits unless
they apply for, and obtain, an order approving an exception to those limits. Although exceptions
to the default limits are not unusual, AOGCC carefully evaluates each application, and typically
grants them only when actual geologic conditions demonstrate that the proposed subsurface
location of a well is necessary to reach otherwise unreachable oil or gas and that both the rights of
adjacent leaseholders and landowners and underground drinking water can be protected. As a
general matter, AOGCC does not have extensive authority over surface impacts such as noise,
emissions, or construction.
This notice does not contain all the information filed by Hilcorp. To obtain more information,
contact the AOGCC’s Special Assistant, Samantha Coldiron, at (907) 793-1223 or
samantha.coldiron@alaska.gov.
The AOGCC has tentatively scheduled a public hearing on this matter for May 13, 2025, at 10:00
a.m. via Microsoft Teams. The hearing, which may be changed to full virtual, if necessary, will be
held in the AOGCC hearing room located at 333 West 7th Avenue, Anchorage, AK 99501. The
audio call in information is (907) 202 7104 Conference ID: 595 741 512# #. Anyone who wishes
to participate remotely using MS Teams video conference should contact Ms. Samantha Coldiron
at least two business days before the scheduled public hearing to request an invitation for the MS
Teams. To request that the tentatively scheduled hearing be held, a written request must be filed
with the AOGCC no later than 4:30 p.m. on March 28, 2025.
If a request for a hearing is not timely filed, the AOGCC may issue an order without a hearing. To
learn if the AOGCC will hold the hearing, call (907) 793-1223 after April 1, 2025.
In addition, written comments regarding this application may be submitted to the AOGCC, at 333
West 7th Avenue, Anchorage, AK 99501 or samantha.coldiron@alaska.gov. Comments must be
received no later than 4:30 p.m. on April 16, 2025, except that, if a hearing is held, comments must
be received no later than the conclusion of the May 13, 2025, hearing.
If, because of a disability, special accommodations may be needed to comment or attend the
hearing, contact Samantha Coldiron, at (907) 793-1223, no later than May 8, 2025.

Well spacing regulations protect the oil and gas rights of adjacent leaseholders and landowners
and maximize resource recovery by establishing default limits on how close, under the land's
surface, oil and gas wells can be to property lines where ownership changes hands. These limits
are set forth in a regulation, 20 AAC 25.055. Operators must abide by the default limits unless
they apply for, and obtain, an order approving an exception to those limits. Although exceptions
to the default limits are not unusual, AOGCC carefully evaluates each application, and typically
grants them only when actual geologic conditions demonstrate that the proposed subsurface
location of a well is necessary to reach otherwise unreachable oil or gas and that both the rights of
adjacent leaseholders and landowners and underground drinking water can be protected. As a
general matter, AOGCC does not have extensive authority over surface impacts such as noise,
emissions, or construction.

Commissioner Chmielowski:
Hilcorp Alaska, LLC (“Hilcorp”), as Operator of the Milne Point Unit, hereby submits this
application for spacing exception to drill two (2) injection wells, the Milne Point Unit H-
41 and H-43, collectively referred to as (“H-Pad Injection Wells”)in the Shrader Bluff Oil
Pool. The proposed productive interval and location for the proposed drill operations are

Hilcorp submits this application to ensure compliance with 20 AAC 25.055(a)(1), which
states “for a well drilling for oil, a wellbore may be open to test or regular production1
within 500 feet of a property line only if the owner is the same and the landowner is the
same on both sides of the line.”
The H-41 and H-43 wells will be injection wells. In order to achieve maximum injectivity
of the wellbore, Hilcorp intends to flow back each well for up to 60 days to fully clean out
the wellbore to reduce the effect of near-wellbore damage caused by drilling fluid invasion
which will ensure maximum injectivity. The initial flowback will consist mostly of drilling
and completion fluids, including cuttings and other fine materials that will be flowed to
tanks, transported offsite and disposed of in accordance with State regulations. Once the
flowback has less than 0.5% solids, the flow stream will be sent to the Milne Point
production facility to continue cleaning up. In order to prevent waste, Hilcorp intends to
sell any oil processed and separated at the production facility.
Hilcorp is not proposing to drill and complete any of these wells as a producing oil well.
Associated oil will only be “produced” for 60 days to ensure the wellbore is as clean as
possible before commencing injection operations. The intent of this application is to allow
Hilcorp to prevent waste that may occur as a result of its cleanup process by:
1. Ensuring a clean wellbore to achieve maximum injectivity.
2. Enhancing recovery of the offset production well which will be spaced between
each injection well.
3. Avoid disposal of sales quality oil.
Additionally, well spacing within the Schrader Bluff Oil Pool is governed by Rule 2 of
Conservation Order 477a:
1 AS 31.05.170(14) “regular production” means continuing production of oil or gas from a well
into production facilities and transportation to market, but does not include short term testing,
evaluation, or experimental pilot production activities that have been approved by permit or
order of the commission.”

Spacing Exception Application
Milne Point Unit H-41 & H-43 Injection Wells

Page 3 of 8
Rule 2. Spacing (Revised by CO 477.005)
There are no restrictions as to well spacing except that no pay shall be opened in a
well closer than 500 feet from the exterior boundary of the affected area.
The proposed H-Pad Injection Wells operations target undrained reserves that cannot be
reached by wells conforming to applicable spacing restrictions. Approval of short-term pre-
production of the proposed H-Pad Injection Wells allows for protection of its correlative
rights by recovering the otherwise stranded reserves and ensures future maximum
injectivity of each wellbore. Additionally, the correlative rights of all affected owners,
landowners and operators will be protected and enhanced by the long-term support
provided by the polymer injection.
The proposed production well which will be drilled between each of the H-Pad Injector
Wells, as shown on Exhibit “A-1”, will be further than 500 feet from the exterior boundary
of the affected area and does not require a spacing exception approval. Hilcorp anticipates
drilling operations of the H-Pad Injection Wells to commence as soon as June 2025.
As of the date of delivery of this application, and in accordance with 20 AAC 25.055(d)(1),
notice of Hilcorp’s intent to drill the H-Pad Injection Wells has been sent by certified mail
to those certain owners, landowners, and operators of property within 1,000 feet of the well
listed in Exhibit “B”. A copy of the notice and corresponding certified mailing receipts
have been attached to this application.
Pursuant to 20 AAC 25.055(d)(3), and attached as Exhibit “C”, is an affidavit executed by
a person acquainted with all pertinent facts of this application and verifying that all facts
set forth herein are true.
It is requested that the Commission approve, by Administrative Approval, pursuant to 20
AAC 25.556(d), an exception to the well spacing for drilling the H-Pad Injection Wells.
If you require additional information or would like to have a technical meeting regarding
this application, please contact Katie Cunha, Geologist, at (907) 564-4786, or me at (907)

Jessie Chmielowski, Commissioner
Alaska Oil and Gas Conservation Commission
333 West 7th Avenue, Suite 100
Anchorage, Alaska 99501
RE: Application for Spacing Exception
Milne Point Unit H-31 Extended Well (Injector)
Amendment to CO477.009
Commissioner Chmielowski:
On January 12, 2024, Hilcorp Alaska, LLC (“Hilcorp”) submitted an application to drill
the Milne Point Unit H-31 well which was approved under CO477.009. After further
review, Hilcorp would like to extend the well a total of 5,440’. The new, proposed top
productive horizon (TPH) has been shifted eastward by 1,460’ and the bottom hole location
(“BHL”) of the well has been shifted an additional 3,980’ west to access additional
resources within the same lease as previously approved in order to protect the correlative
rights of the State, and prevent waste of resources that otherwise might not be captured.
There will be no change to the location of the BHL as to the exterior boundary of the lease
line.
Now therefore, Hilcorp, as Operator of the Milne Point Unit, hereby submits this amended
application for spacing exception to drill the Milne Point Unit H-31 Well (“H-31 Well”)
with an adjusted TPH and extended BHL in the Shrader Bluff Oil Pool. The proposed
productive interval and location for the proposed drill operations are listed below and
further depicted on the attached Exhibit “A”:
Surface Location (Same as CO477.009):
x State Lease ADL 25906
x 2,223’ FNL, 1,293’ FWL
x Section 34, T13N-R10E, UM
Top of the Producing Interval (Revised from CO477.009):
x State Lease ADL 25906
x 70’ FSL, 682’ FEL
x Section 34, T13N-R10E, UM
Bottom Hole Location (Revised from CO477.009):
x State Lease ADL 25517
x 70’FSL, 570’ FWL
x Section 31, T13N-R10E, UM

Spacing Exception Milne Point Unit H-31 Well
Extended BHL
March 3, 2025
Page 2 of 6
Compliance with CO477.009: Should this amended application be approved, Hilcorp will
abide by all terms and conditions outlined in CO477.009 for the Milne Point Unit H-31
Well.
Hilcorp submits this application to ensure compliance with 20 AAC 25.055(a)(1), which
states “for a well drilling for oil, a wellbore may be open to test or regular production1 within
500 feet of a property line only if the owner is the same and the landowner is the same on both
sides of the line.”
The H-31 Well will be an injection well. As previously approved in CO477.009, Hilcorp
is requesting to flow back the well for up to 60 days to fully clean out the wellbore to
reduce the effect of near-wellbore damage caused by drilling fluid invasion which will
ensure maximum injectivity. The initial flowback will consist mostly of drilling and
completion fluids, including cuttings and other fine materials that will be flowed to tanks,
transported offsite and disposed of in accordance with State regulations. Once the flowback
has less than 0.5% solids, the flow stream will be sent to the Milne Point production facility
to continue cleaning up. In order to prevent waste, Hilcorp intends to sell any oil processed
and separated at the production facility.
Hilcorp is not proposing to drill and complete a producing oil well. Associated oil will only
be “produced” for 60 days to ensure the wellbore is as clean as possible before commencing
injection operations. The intent of this application is to allow Hilcorp to prevent waste that
may occur as a result of its cleanup process by:
1. Ensuring a clean wellbore to achieve maximum injectivity.
2. Enhancing recovery of the offset H-32 production well.
3. Avoid disposal of sales quality oil.
Additionally, well spacing within the Schrader Bluff Oil Pool is governed by Rule 2 of
Conservation Order 477a:
Rule 2. Spacing.
There are no restrictions as to well spacing except that no pay shall be opened in a well
closer than 500 feet from the exterior boundary of the affected area.
The proposed H-31 Well operations target undrained reserves that cannot be reached by
wells conforming to applicable spacing restrictions. Approval of short-term pre-production
1 AS 31.05.170(14) “regular production” means continuing production of oil or gas from a well
into production facilities and transportation to market, but does not include short term testing,
evaluation, or experimental pilot production activities that have been approved by permit or
order of the commission.”

Spacing Exception Milne Point Unit H-31 Well
Extended BHL

of the proposed H-31 Well allows for the recovery of otherwise stranded reserves and
ensures future maximum injectivity of the wellbore. Additionally, the correlative rights of
all affected owners, landowners and operators will be protected and enhanced by the long-
term support provided by the proposed H-31 injection.
As of the date of delivery of this application, and in accordance with 20 AAC 25.055(d)(1),
notice of Hilcorp’s intent to drill the H-31 Well has been sent by certified mail to those
certain owners, landowners, and operators of property within 1,000 feet of the well listed
in Exhibit “B”. A copy of the notice and corresponding certified mailing receipts have been
attached to this application.
Pursuant to 20 AAC 25.055(d)(3), and attached as Exhibit “C”, is an affidavit executed by
a person acquainted with all pertinent facts of this application and verifying that all facts
set forth herein are true.
It is requested that the Commission approve, by Administrative Approval, pursuant to 20
AAC 25.556(d), an exception to the well spacing for drilling the extended BHL of the H-
31 Well, amending CO477.009.
If you require additional information or would like to have a technical meeting regarding
this application, please contact Katie Cunha, Geologist, at (907) 564-4786, or me at (907)

Spacing Exception
Milne Point Unit H-21 Well
March 3, 2025
Page 2 of 6
The H-21 Well will be an injection well. In order to achieve maximum injectivity of the
wellbore, Hilcorp intends to flow back this well for up to 60 days to fully clean out the
wellbore to reduce the effect of near-wellbore damage caused by drilling fluid invasion
which will ensure maximum injectivity. The initial flowback will consist mostly of drilling
and completion fluids, including cuttings and other fine materials that will be flowed to
tanks, transported offsite and disposed of in accordance with State regulations. Once the
flowback has less than 0.5% solids, the flow stream will be sent to the Milne Point
production facility to continue cleaning up. In order to prevent waste, Hilcorp intends to
sell any oil processed and separated at the production facility.
Hilcorp is not proposing to drill and complete this well as a producing oil well. Associated
oil will only be “produced” for 60 days to ensure the wellbore is as clean as possible before
commencing injection operations. The intent of this application is to allow Hilcorp to
prevent waste that may occur as a result of its cleanup process by:
1. Ensuring a clean wellbore to achieve maximum injectivity.
2. Enhancing recovery of the offset production well which will be spaced between
each injection well.
3. Avoid disposal of sales quality oil.
Additionally, well spacing within the Schrader Bluff Oil Pool is governed by Rule 2 of
Conservation Order 477a:
Rule 2. Spacing (Revised by CO 477.005)
There are no restrictions as to well spacing except that no pay shall be opened in a well
closer than 500 feet from the exterior boundary of the affected area.
The proposed H-21 Well operations target undrained reserves that cannot be reached by
wells conforming to applicable spacing restrictions. Approval of short-term pre-production
of the proposed H-21 Well allows for protection of its correlative rights by recovering the
otherwise stranded reserves and ensures future maximum injectivity of the wellbore.
Additionally, the correlative rights of all affected owners, landowners and operators will
be protected and enhanced by the long-term support provided by the polymer injection.
The proposed production well which will be drilled north of the H-21 Well, as shown on
Exhibit “A”, will be further than 500 feet from the exterior boundary of the affected area
and do not require a spacing exception approval. Hilcorp anticipates drilling operations of
the H-21 Well to commence as soon as June 2025.
As of the date of delivery of this application, and in accordance with 20 AAC 25.055(d)(1),
notice of Hilcorp’s intent to drill the H-21 Well has been sent by certified mail to those
certain owners, landowners, and operators of property within 1,000 feet of the well listed

would allow for further development of the Schrader Bluff reservoir from the Milne Point
Raven-Pad into the Nikaitchuq Unit, beginning as soon as April 2025. Figure 2 depicts the
location of the proposed Schrader Bluff Oa Drill Wells from the Milne Point Raven Pad.
Blue lines indicate injectors, while green lines are producers.
Well data within the proposed Expansion Area shows that the Schrader Bluff is structurally
continuous across the Nikaitchuq and Milne Point Units. Hilcorp has submitted
confidential seismic data to the Commission (Figure 3) depicting a seismic cross section
and Type Wells through the Nikaitchuq Unit (West to East) and the Milne Point Unit
(Northwest to Southeast). Reviewing this internal seismic data gives Hilcorp high
confidence that the Schrader Bluff formation is a continuously mappable seismic horizon.
Figure 3.1, marked as confidential, depicts the shared lease line between the Nikaitchuq
Unit, Milne Point Unit, and the known Schrader Bluff OA Sand Well Tops. The well
control and mappable fluid contact also indicate that the Schrader Bluff is structurally
continuous across the units.
As of the date of delivery of this application, and in accordance with 20 AAC 25.055(d)(1),
notice of Hilcorp’s proposal to expand the Affected Area of CO 477a has been sent by
certified mail to those certain owners, landowners, and operators of property within 1,000
feet of the proposed Expansion Area listed in Exhibit “A”. A copy of the notice and
corresponding certified mailing receipts have been attached to this application.
Pursuant to 20 AAC 25.055(d)(3), and attached as Exhibit “B”, is an affidavit executed by
a person acquainted with all pertinent facts of this application and verifying that all facts
set forth herein are true.
It is requested that the Commission schedule a public hearing to review Hilcorp’s
application for expansion of the SBOP in accordance with 20 AAC 25.540.
