10/22/2020: 1 traveled to Prudhoe Bay Unit U -Pad for a surface abandonment
inspection on well U -02A and met Hilcorp representative Jaycen Sala. Excavation had
been completed and the tree removed. The casing cut was determined to be adequate
(at least 3 feet below tundra grade) and casing tops exposed. All casing strings and the
tubing were filled to surface but upon checking for rigidity of the cement found the outer
annuli (13 3/8" x 9 5/8" OA and 20" x 13 3/8" OOA) was soft and mushy. Hilcorp was
instructed to dig out as much of the soft material from the 2 annuli and top off with fresh
cement. I verified the well information on the marker plate as found in the approved
Sundry. I told Operator to give cement at least 12 hours curing time to harden, and I
would return to verify.
10/23/2020: Traveled back PBU U -02A to verify the cement integrity in the OA and
OOA. The cement had not quite hardened, so Hilcorp was instructed to allow until
morning of the next day to harden and I would return to verify.
10/24/2020: 1 stopped by PBU U -Pad and verified cement top and rigidity. Cement to
surface on all strings was solid. I allowed them to proceed welding on the marker plate
and backfill the excavation.

Remarks:
I arrived on location to witness the tag and pressure test of the bottom cement plug on PBU U -02A. These tests where both to
be completed by a Coil tubing unit. I witnessed the tag on the top of the cement plug (TOC) @ 9508 feet MD . After confirming
the top of the plug 50001b was stacked on top. The operator then pulled up hole and re -tagged showing the TOC to be at the
same depth. The next step was for them to run and set a cement retainer to isolate the tubing above and pressure test the plug.
The retainer was set at a depth 9490ft, the ball was dropped into the coil and pumped down to the retainer. After the ball was
confirmed at the retainer 3700 psi was applied to the coil in order to shear the ball and allow communication below the retainer. I
didn't see any definitive sign that the ball had sheared and allowed communication below the retainer. The operator pulled up
50001b and then stacked 50001b on the retainer confirming it to be set. I asked them how they could give me a 100% positive
answer that the ball was sheared, and we would be testing the cement plug and not just the coil. The tool hand told me that /
pulling up on the coil would allow the ball to drop the rest of the way even if pumping didn't allow it to drop all the way. I
witnessed a passing pressure test on Plug 1 TOC (below retainer) as long as the tool was open. ✓

Expected Start Date:
May 1, 2019
History:
U-02 was drilled and completed as a conventional Z4 producer in 1985. U-02 had significant
corrosion problems. The original 3-1/2" tubing was replaced 7/90 and a 7" scab liner installed to
repair a casing leak. The well was shut-in 5/19/98 due to repeated casing integrity problems
and poor production, then side tracked in 1999. U -02A reached a depth of 13429' md, —1700'
below plan. The well did not reach the primary target due to high fluid loss intervals, fault
related fractures, and the risk of a poor cement job, thus finalized as a barefoot completion. U -
02A was shut-in 8/26/02 (due to T x IA communication). It passed an NFT on 10/24/02 but POP
attempts were unsuccessful due to low flow from the reservoir and a hole in the tubing.
Attempts were made change out the GLV from Station #4, it was found damaged and a piece
broken off — possible piece of the GLM sticking out into the wellbore. Fishing runs found fill /
obstructions at —6989' wlm, with several bailing runs recovering the missing GLV fishing neck,
mud like material, solid clay and cement while working down to 7023' wlm. On 12/8/03, a
production casing leak and tubing leak was identified by E -Line LDL at 2960' and in the tubing
and 3170' and in the production casing.
Objective:
Perform a full P&A on the well placing cement plugs in the wellbore. Excavate and cut casings
3' below original tundra level and install marker plate.

Subject: Corrosion. Inhibitor Treatments of GPB U Pad
Dear Mr. Maunder,
Enclosed please find multiple copies of a spreadsheet with a list of wells from U Pad
that were treated with corrosion inhibitor in the surface casing by conductor annulus.
The corrosion inhibitor is engineered to prevent water from entering the annular space
and causing external corrosion that could result in a surface casing leak to atmosphere.
The attached spreadsheet represents the well name, API and PTD numbers, top of
cement depth prior to filling and volumes of corrosion inhibitor used in each conductor.
As per previous agreement with the AOGCC, this letter and spreadsheet serve as
notification that the treatments took place and meet the requirements of form 10 -404,
Report of Sundry Operations.
If you require any additional information, please contact me or my alternate, Jerry
Murphy, at 659 -5102.
Sincerely,
Torin Roschinger
BPXA, Well Integrity Coordinator

Re: Request to Commingle Test Production from S;200:~nd W-200 Wells
Dear Chairman Christenson:
As you are aware, BP as PBU WOA Operator on behalf of the lease owners, has drilled two
Schrader test wells in the PBU WOA and requested approval of a Pilot Production Plan. S-200
(aka SB-01) bottomed on T12N-R12E UM Sec. 27 within ARCO/Exxon lease ADL 28258. W-
200 (aka SB-02) bottomed on Sec. T11N-R12E Sec. 21 within Mobil/Phillips/Chevron lease ADL
28263. Both wells have been briefly tested from various Schrader Bluff formation intervals, but
additional appraisal completion or testing work remains to be performed before the pilot period.
Both wells will be completed in the Schrader Bluff formation, no approval is requested for
downhole commingling with formations other than the Schrader Bluff. The wellwork is expected
to be performed in September and October 1999. Production testing is not expected to exceed
seven days per well.
Consistent with existing practices, BP requests approval by the AOGCC on behalf of
ARCO/Exxon and Mobil/Phillips/Chevron to commingle production with other pools for
processing at PBU Gathering Center 2 during the testing period. Production allocation will be
based on the existing well test methodology approved by the AOGCC, based on well tests
conducted at S and W pads. Similar approval was granted by letter of 12/18/97. BPX will
undertake to advise the Division of the status of well operations in a timely manner.
If you have any questions, please contact Steve Deckert at (907) 564-4128.

"Gunk" Squeeze for Lost Returns
Well U-02A from rig Nabors 9ES is presently horizontal at 15,568'MD in the Ivishak formation, drilling has been
halted due to excessive loss of returns to an expected fault which was crossed. At the current time, concentrated pills
of LCM has not proved effective in halting losses.
SSD plans to pump one or two more pills of highly concentrated LCM in efforts to stop the loss of seawater which is
our fluid presently in the hole. Subsequent to these pills we propose to pump a "Gunk" squeeze composed of mineral
oil and 300-400 #Pobl of bemonite gel. When the gel mixes with available water a reD' thick product is generated
which has proved able to seal loss zones in the past,
SSD has available a stockpile of the Conoco LVT-200 mineral oil which was previously used as drilling mud on the
13-02B well last year in efforts to control running Kingak shales. As opposed to purchasing new mineral oil we plan
to use part of this existing stock of mineral oil in the "gunk" squeeze which is planned.
Your acceptance of this proposal is requested.
Regards,
SSD SDE

BOP Test, Nabors #9ES
BPX U-02
Prudhoe Bay Unit
98-0239
Non-Confidential
Sunday, January 31, 1999; I witnessed a weekly BOP test on Nabors rig #9ES drilling
BPX well #U-02 in the Prudhoe Bay field.
The rig was ready to test within a hour of when I arrived. The stack was filled with the
only available water on board, which was quite hot. This was in anticipation of building
mud for the new section of hole to be drilled. I questioned the use of such warm fluid for
testing, as this was the only water available at the time I allowed for the test to begin.
The warm fluid gave us much problems by contracting as it cooled in the stack showing
a pressure decline during each separate test. I requested that we change fluid, the only
other suitable fluid was the mud in the trip tank. Normally, mud is not used due its
compressibility and possible sealing of slight leaks, in light of this rigs short but good
record I allowed for the mud to be used but held the tests slightly longer than I normally
would. I mentioned to Lee Martin (Toolpusher) that in the future it would be required to
have water at ambient temperature for test fluid.
The test was restarted and all BOPE functioned properly and held its respective
pressure tests. With the exception of the warm fluid problem, the test proceeded
smoothly and showed this rig to be in good shape for finishing this well.
SUMMARY: I witnessed the weekly BOP test on Nabors 9ES, No failures observed.

U-02A, Possible Second Sidetrack
Date: January 20, 1999
U-02A was planned as a 7,000' extended horizontal undulating sidetrack, drilling to two (2) Zone 4 targets.
The well was kicked out of 7 "casing at _ 9,900' MD in the Sag River formation and directionally drilled
through Z4 Target #1 at _+ 11,800' MD. Four (4) faults were crossed through Target #1 without any hole
problems. The well was then turned 60° WNW and directionally drilled through Z4 Target #2 crossing four
(4) additional non-troublesome faults. At ± 15,568' MD massive loss circulation occurred when fault ,f9 was
encountered; static fluid losses to the fault were as high as 200 bbl/hr (the rig switched from FIo-Pro mud to
filling the hole with 8.4 ppg seawater). Three large MI Kwikseal/Coarse Nut Plug LCM pills were pumped into
the fault where static losses decreased to 4 - 5 bbl/hr. Fault #9 was then drilled across to 15,628' MD where
static loss circulation dramatically increased to as high as 400 bbl/hr. When drilling the fault, the Nabors 9ES
driller described that he drilled through a void for about 5 feet. Three more coarse mix, 120 ppb/100bbl
Kwlkseal/NutPlug pills were mixed and pumped to slow the loss circulation. Static losses again slowed to
< 20 bbl/hr to the fault. The fault was then penetrated a second time and massive loss circulation occurred
again; as high as 400 bbl/hr. The BHA was changed to allow for larger and more diverse LCM pills to be
pumped. One 50 bbl Iow compressive strength cement pill and two (2) more high density Kwikseal/Nutplug
pills were pumped to the fault with no positive effect. The fault took every type of LCM pill and continued to
take seawater from the wellbore at 100 - 200 bbl/hr static.
Because the fault could not be effectively sealed, hole cleaning while circulating the drill string was very
ineffective. Full circulation and good hole cleaning could not be achieved after fault ~9 was penetrated. The
wellbore was not completely clean of drilling cuttings and had LCM material throughout.
After the cement LCM pill and final two (2) high density Kwikseal/Nutplug was pumped, the drill string was
pulled out of the hole. At + 14,000' MD the hole started to get sticky and acted as if the hole was packing off.
Circulation could no longer be achieved (due to losses to the fault and due to packing off) but the drill string
could be rotated and could still be pulled out of the hole. At 12, 745' MD the drill stdng could no longer be
pulled out of the hole and became stuck.
The drill pipe was backed off at _+ 10,900' and a jarring assembly RIH. The 1,845' fish was jarred up hole 60'
but could not be completely recovered.
Fishing operations continue today. I} the fish is not recovered soon, the fishing assembly will be backed off, a
cement plug will have to be set on top of the fish and a new Z4 wellbore will have to be ddlled. Drilling will
stop prior to encountering fault #9 with the next directional plan.
In the event that a second sidetrack wellbore will be needed to complete this well, a complete Sundry Permit
· will be submitted.

Drilling Discussion
Well Objective
The NW fault block of the U - Pad has 129 million reservoir bbls total pore volume, of which
approximately 107 million (83%) will be under flood. U-02A is a critical well for flood and MI
development, and will be a 5,300' undulating Z4B producer receiving support from three injectors.
This well will capture the reserves associated with current producers U-12 (presently P&A'd for
sidetrack) and U-02, as well as the undrained region in the western most part of the U pad. The
unrisked incremental reserves are 6.02 mmstb.
The expected average first year incremental oil rate is 2645 bopd at 60% WCUT and 699 scf/stb GOR.
Drilling Objective Original Wellbore
The drilling objective was to pull the existing 4 ½" x 3 ½" tubing, mill up and retrieve the existing
production packer, dress the P & A cement plug to just below the Sag River perforations, set a
whipstock and mill through 7' liner casing into the Sag River formation. Directionally drill this 7,000'
undulating extended horizontal sidetrack through two Z4B targets to TD at 16,863'. Run, cement and
test 4 ½" liner, perforate and complete with 4 ½" tubing.
After the decompletion phase was successfully completed, the well was kicked off into the Sag River
formation, successfully steered into and through the first Z4 target and into Z4 target 4/2. Eight faults
were drilled without incident. At 15,568' MD, fault gO was encountered where massive lost circulation
losses were incurred ( as high as 400 bbl/hr). Eleven (11) LCM pills of various sizes and properties
were pumped to the fault to seal off the fault. None worked effectively. Because the fault took so much
fluid, full circulation and good hole cleaning could never be achieved. After LCM pill 4/ 11 was
pumped the drill string was POOH. At 12,745' MD, the DP became stuck and had to be severed (top of
fish 11,014'). A cement plug was set and dressed down to 10,390' where a second EHST (extended
horizontal sidetrack) will be drilled out of the original wellbore.
Drilling Objective Sidetrack Wellbore
The new Z4 wellbore will be drilled from KOP at 10,390' to TD at 15,312' MD. The well will have
two undulations (@ 1,300' in length each) through one Z4 target.
No large faults are predicted but (10) small faults will occur with the potential for fluid loss. Several
small faults (10'-35') have been interpreted, but poor data quality precludes correlation of these faults
laterally for any significant mapable extent.
The designed well path optimizes structural position and reservoir exposure with undulations that will
be geosteered using MWD/GR/Res (real time). The criteria for geosteering are approximately 20'
standoff from the HOT and ensuring the wavelength of the undulation is targeted at 1400 feet or less.
The well will be completed as a Zone 4B producer with a 4 ½", L-80, 12.64/tubing, (6) GLM's and
WOA tailpipe assy. The GLM's will be run with depths determined after log evaluation.
DRILLING HAZARDS AND CONTINGENCIES
Always have two levels of tested isolation before NU/ND.
SURFACE CLOSE APPROACH WELL SHUT-INS
There is no well that will need to be shut-in during the rig move on and off of the well. Careful
coordination with any ongoing pad or facility operations or activities will be initiated prior to
commencing the rig move.
DRILLING CLOSE APPROACH WELL SHUT-INS
No shut-ins identified on Sperry Sun directional well plan due to close approach requirements.
PORE PRESSURE: The pore pressure in the Sag River (KOP) is expected to be near 7.4 ppg
EMW and the Sadlerochit is expected to be near 7.4 ppg. 8.7 - 8.8 ppg mud will be used drilling
the Sag River, Shublik and Sadlerochit formations and will provide sufficient overbalance to the
reservoir pressure.
HOLE PROBLEMS
The well's design cuts 10 small faults in the reservoir section, however only (1) of the faults are large
enough and areally extensive to be mapped. Be prepared for the possibility of lost circulation. The
original wellbore, U-02, did not experience lost circulation. Other wells in the intermediate vicinity
have experienced minor lost circulation. The original wellbore, U-02A, experienced massive loss
circulation to fault 4/9.
No major conductive faults have been identified and no major hole problems are expected.
H~S: U-Pad is not an H2S Pad
There are no reported incidents of H2S at well U-02. H2S precautions will be in effect at all times.
These include (but are not limited to):
· Regular H2S drills (minimum of two per week)
· Proper training of all permanent onsite personnel, unescorted visitors and temporary
onsite personnel;
· H2S monitors with both audible and visual alarms;
· Access to 5-minute emergency escape air packs;
· Personal H2S monitors;
· Functional wind indicator;
· Posted evacuation routes (minimum of two);
· Muster points in designated safe areas;I-Ig.S;
--
· Functional communications between rig camp and rig floor.
Fault Evaluation
See Hole Problems. The original wellbore, U-02A, experienced massive lost circulation. Other
wells in the immediate vicinity have experienced lost circulation: U-03, U-11, U-13, U-14, H-
10, H-12, and H-32.
Casing Shoe Kick Tolerance
The smallest kick tolerance for the 9 5/8" casing shoe is calculated as infinite of influx assuming a
swabbed gas influx at the Sag River formation along the planned directional path. Based on 8.7 ppg
MW (TSAG 9,883' MD & 8,725' TVDss, 7.8 ppg reservoir pore pressure), and min. frac at shoe of
12.0 ppg.

Drilling Discussion
Well Obiective
The NW fault block of the U - Pad has 129 million reservoir bbls total pore volume, of which
approximately 107 million (83%) will be under flood. U-02A is a critical well for flood and MI
development, and will be a 7,000' undulating Z4B producer receiving support from three injectors.
This well will capture the reserves associated with current producers U-12 and U-02, as well as the
undrained region in the western most part of the U pad. The unrisked incremental reserves are 6.02
mmstb.
The expected average first year incremental oil rate is 2645 bopd at 60% WCUT and 699 scf/stb GOR.
Drilling Objective
The drilling objective is to pull the existing 4 ½" x 3 ½" tubing, mill up and retrieve the existing
production packer, dress the P & A cement plug to just below the Sag River perforations, set a
whipstock and mill through 7' liner casing into the Sag River formation. Directionally drill this 7,000'
undulating extended horizontal sidetrack thru two Z4B targets. Run, cement and test 4 ½" liner,
perforate and complete with 4 ½" tubing.
No large faults are predicted but small faults will occur with the potential for fluid loss. Several small
faults (10'-20') have been interpreted, but poor data quality precludes correlation of these faults
laterally for any significant mapable extent.
The designed well path optimizes structural position and reservoir exposure with undulations that will
be geosteered using MWD/GR/Res (real time). The criteria for geosteering are approximately 20'
standoff from the HOT and ensuring the wavelength of the undulation is targeted at 1500 feet or less.
The well will be completed as a Zone 4B producer with a 4 ½", L-80, 12.6# tubing, (6) GLM's and
WOA tailpipe assy. The GLM's will be run with depths determined after log evaluation.
DRILLING HAZARDS AND CONTINGENCIES
Always have two levels of tested isolation before NU/ND.
SURFACE CLOSE APPROACH WELL SHUT-INS
There is no well that will need to be shut-in during the rig move on and off of the well. Careful
coordination with any ongoing pad or facility operations or activities will be initiated prior to
commencing the rig move.
DRILLING CLOSE APPROACH WELL SHUT-INS
No shut-ins identified on Sperry Sun directional well plan due to close approach requirements.
PORE PRESSURE: The pore pressure in the Sag River (KOP) is expected to be near 7.4 ppg
EMW and the Sadlerochit is expected to be near 7.4 ppg. 8.7 - 8.8 ppg mud will be used drilling
the Sag River, Shublik and Sadlerochit formations and will provide sufficient overbalance to the
reservoir pressure.
HOLE PROBLEMS
The well's design cuts 10 small faults in the reservoir section, however only (2) of the faults are large
enough and areally extensive to be mapped. Be prepared for the possibility of lost circulation. The
original wellbore, U-02, did not experience lost circulation. Other wells in the intermediate vicinity
have experienced minor lost circulation.
No major faults have been identified and no major hole problems are expected.
H__~_S: U-Pad is not an H2S Pad
There are no reported incidents of H2S at well U-02. H2S precautions will be in effect at all times.
These include (but are not limited to):
· Regular H2S drills (minimum of two per week)
· Proper training of all permanent onsite personnel, unescorted visitors and temporary
onsite personnel;
H2S monitors with both audible and visual alarms;
Access to 5-minute emergency escape air packs;
Personal H2S monitors;
Functional wind indicator;
Posted evacuation routes (minimum of two);
Muster points in designated safe areas;H_a_S;
Functional communications between rig camp and rig floor.
Fault Evaluation
See Hole Problems. The original wellbore, U-02, did not experience lost circulation. Other
wells in the immediate vicinity have experienced lost circulation: U-03, U-11, U-13, U-14, H-
10, H-12, and H-32.
Alert: The kick off will be high in the Sag River in a known fault area. There is a remote
possibility of drilling into the Kingak shale if a downthrown fault is encountered soon after
Kick off. Carefully check return cuttings when drilling out of the window, if the Kingak is
encountered we will plug back and kick off deeper.
Casing Shoe Kick Tolerance
The smallest kick tolerance for the 9 5/8" casing shoe is calculated as infinite of influx assuming a
swabbed gas influx at the Sag River formation along the planned directional path. Based on 8.7 ppg
MW (TSAG 9,883' MD & 8,725' TVDss, 7.8 ppg reservoir pore pressure), and min. frac at shoe of
12.0 ppg.
