Adrienne,
My Response to your questions below in red.
I’m copying Jim Regg to inform him of the change in BOP test pressure and MPSP as
noted below in your question #2.

Subject: RE: PERMIT Number 225-098
Bryan,
I have a few questions on the approved PTD for Gubik Unit #1:
1. Inclination-only survey required is marked Yes. I’ve not seen this required for a P&A
before. Can you please clarify if this is accurate? No directional survey is required since
you are not drilling new hole. -bjm
2. Condition of Approval #1 states BOP test to 1600 psi. However, Procedure Step 3.2.2
was edited to change the BOP test pressure to 1000 psi. Could we edit Condition of
Approval #1 to match? Yes. BOP test to 1000 psi. I should also have corrected the BHP
⚠️CAUTION: EXTERNAL SENDER This email originated from outside of the
to 950 psi and MPSP = 786 psi per your 1/26/26 email. Rig supervisor should have a
copy of this email available for the AOGCC inspector during the BOP test. -bjm
3. Condition of Approval #2 states: “ice plugs to be drilled in snubbing mode, with pipe
held in rotary slips and stripping annular closed, flow diverted through choke.” We will
be lined up to divert flow through the choke if gas is encountered, but the plan for
normal operating conditions is to route returns to the mud tank via the bell nipple bleed-
off line directly below the stripping annular. This aligns with the snubbing contractor’s
standard practice. Would you be willing to edit Condition of Approval #2 to read as
follows: “Ice plug to be drilled with pipe held in rotary slips and stripping annular closed.
Be prepared to divert flow through choke if gas is encountered.” Yes, this change is
approved. -bjm
4. Condition of Approval #5 states we need to tag all cement plugs with full string weight,
except surface plug. Does this apply to Contingency Plug #2a?
a. Contingency Plug #2a is 75’ of cement placed on top of CIBP Plug #1, per 20 AAC
25.112 (c)(1)(E).
b. Could we satisfy 20 AAC 25.112 (g)(1) by stacking weight on CIBP Plug #1 before
placing cement (Contingency Plug #2a) on top of it? Yes. But if contingency
plugging is not required, then still need to tag TOC for plug 2 at ~686’ MD. -bjm
5. The BOP stack drawing shows 2-7/8” slip rams at the very bottom. In our case, these are
not serving as BOPE; their purpose is to secure a pipe guide that will aid entry into the
existing 2-7/8” tubing. After further discussion with the snubbing contractor, I would like
to use a hanger flange instead. See attached brochure. Is this acceptable? Yes, please
submit updated BOP stack diagram. -bjm
Thanks,

APPLICATIONSMTI TEAM MANUFACTURED ITS 1ST HANGER FLANGE IN 2006
HANGER
FLANGES
Hanger Flanges are safety devices used to hang off tubing stings during well servicing,
and underbalanced drilling operations. They are manufactured with manual extended/
retracted rams that can be engaged on a range of tubular sizes while providing Full
Bore when the rams are fully retracted. They are manufactured with similarities to the MT
Gripper Slip Dies to vertically hold the tubular string in place using the Hanger Flange.
• Manufactured from NACE material for
H2s Service
• Safest way of Hanging Tubing String
under Live Well Conditions
• Mostly installed as part of BOP Stack
as a safety device
• Advance Alignment design for Ram
Anti-Rotation Stack as a safety device
• Dual Seal Design for Long life, without
Packing Adjustment
• Tested to hang 1.5 Rating of no
permanent deflection of Rams
• Serrated, Tool Steel Double Drawn
Heat Treated Rams to secure pipe
• Option of Integral Bowen Union

HIGHLIGHTED FEATURES
Over the years the Mitey Titan team has prototyped and tested various
improvements to MT Hanger Flange designs. The new Hanger Flanges
are extremely well built with a Ram Alignment System that is practical
to manufacture and use. It’s field repairable and is intended to fulfill its
application requirements.

1 General Plug & Abandonment Design
Gubik Unit #1 was drilled in 1963 under Permit to Drill number 163-013. Well tests indicated no economic
production. The well was partially plugged in 1966, but no surface plug was installed, and the wellhead
was not cut off. 2-7/8 kill string and 7 casing are full of fresh water (ice) from 1359 (top of existing
cement plug) to surface.
Thru Tubing Solutions, Cudd Pressure Control and ASRC representatives visited the site in June 2023 to
confirm wellhead specifications and height. The wellhead top flange is 7-1/16, 3000 psi working pressure,
and is located approximately 2 below ground level.
Bottomhole pressure estimate:
16.0 ppg mud weight before perforating 7 casing * 0.052 * 2110 ft TVD = 1756 psi
Maximum potential surface pressure:
1756 psi (0.1 psi/ft * 2110 ft TVD) = 1545 psi
2 Objective
Complete permanent plug and abandonment of the subject well, excavate and cut casings three feet below
original tundra grade and weld permanent marker cap.
3 Procedure
3.1 Site Preparation
3.1.1 Build snow trail from Franklin Bluffs. Approximately 70 miles from Franklin Bluffs to Gubik
Unit #1.
3.1.2 Begin site remediation.
3.1.3 Notify AOGCC Inspectors 48 hours before commencing hot tap.
3.1.4 Hot tap dry hole marker, top flange, and side outlet and verify zero pressure. Record and bleed
any pressure. Monitor for 1 hour for potential pressure build up.
3.1.5 Begin excavation and leveling required for upcoming wellwork.

Section 1: General Plug & Abandonment Design
Bottomhole pressure estimate: 950 psi at 1640 TVD.
This estimate is based on the shut-in bottomhole pressure measured during a 9/19/63 drill stem
test (DST) of the 1662 1674 perforated interval, which represents the highest-pressure interval in
the well. The packer and pressure gauge depth for this DST were not recorded. For other DSTs
conducted in this well, the packer and gauge were set approximately 18 35 above the top
perforation. For purposes of this bottomhole pressure estimate, a gauge depth of 1640 TVD
(approximately 22 above the top perforation) was assumed.
Maximum potential surface pressure: 950 psi (0.1 psi/ft * 1640 TVD) = 786 psi.

Adrienne,
Id like to discuss plug #2 in step 3.2.10.
The current plan is for a 2.6 bbls cement plug, which is very di icult to place without
contaminating most of it. Would be better to increase cement volume to assure good cement
where you need it.
Need to place cement across surface casing shoe per 20 AAC 25.112(c)(3) unless we know there
is no fresh water aquifer present.
If you run the CBL log before placing cement and determine that there is already cement in the
annulus above the casing shoe, you could then lay one plug from top of CIBP at 1200 to 686 MD
(100 above surface casing shoe.
Would need to tag cement with full string weight after.
Then proceed to setting surface plug.

Bryan,
I am working with the snubbing contractor to generate a piping diagram and will send as soon as its available.
Regarding your other questions:
Primary pressure control:
Annular preventer (stripping annular BOP in attached diagram)
Dual BPVs in workstring
Secondary pressure control:
Second annular preventer (annular BOP in attached diagram)
1-1/4 pipe ram (single gate ram BOP 1-1/4 in attached diagram)

Managing pipe light:
Snubbing slips will always be engaged on the 1-1/4 workstring, preventing it from being ejected under
pipe-light conditions.

Adrienne,
Can you please submit a piping diagram and an explanation of how you will maintain pressure
containment and avoid pipe-light scenario when drilling out the ice plug in step 3.2.3?
Thank you

Adrienne,
Are you planning to perform the ice drilling in snub mode in case there is gas encountered?

Bryan,
Ill nd out whether the CBL can distinguish between cement and ice.
Good point on the extended time it will likely take to thaw the annuli.
For the 2-7/8 x 7 annulus: I expect the ice cleanout/melting run with heated uid inside the 2-7/8 will
take quite a bit of time, which will give ample opportunity for heat transfer to thaw and warm the annulus
before we run the rst CBL.
For the 7 x 11-3/4 annulus: well be doing quite a lot of circulating with heated uid inside the 7 after the
2-7/8 is pulled and before we run the CBL, again giving ample opportunity for heat transfer to thaw and
warm the annulus.
Although we are planning for 12 versus 24-hour full-scale operations, we will have a small night crew so we can
continue circulating heated uid overnight to keep the wellbore warm.
Thanks,

Adrienne,
Just reading over the permit application for P&A of this well.
Is the CBL able to distinguish between cement and ice in the annulus? I think you will need to circulate
hot water for a considerable amount of time to thaw the ice in both the 2-7/8 x 7 annulus and the 7 x
11-3/4 annulus before running CBL and before you will be able to circulate through perf holes. In my
experience, it takes a lot longer than you think to establish communication when trying to thaw a frozen
annulus. I would expect you to circulate for at least 3-6 hrs before you can establish circulation up the
annuli.
