Re:J-25B Permit to Drill
Approval is requested for drilling a CTD sidetrack lateral from well J-25A with the Nabors CDR2/CDR3
Coiled Tubing Drilling.
Proposed plan for J-25B Producer:
See J-25A Sundry request for complete pre-rig details - Prior to drilling activities, screening will be conducted to
drift for whipstock and MIT. E-line will set a 4-1/2"x5-1/2" whipstock. Coil will mill window pre-rig. If unable to set
the whipstock or milling the window, for scheduling reasons, the rig will perform that work.
A coil tubing drilling sidetrack will be drilled with the Nabors CDR2 or CDR3 rig. The rig will move in, test BOPE
and kill the well. If unable to set whipstock pre-rig, the rig will set the whipstock. A single string 3.80" window + 10'
of formation will be milled. The well will kick off drilling in the Ivishak Zone 4 and lands in Ivishak Zone 1. The
lateral will continue in Zone 1 to TD. The proposed sidetrack will be completed with a 3-1/2"x3-1/4"x2-7/8” L-80
solid liner, cemented in place and selectively perforated post rig (will be perforated with rig if unable to post rig).
This completion will completely isolate and abandon the parent Prudhoe Pool perfs.
The following describes the work planned. A wellbore schematic of the current well and proposed sidetrack is
attached for reference.
Pre-Rig Work:
Reference J-25A Sundry submitted in concert with this request for full details.
1. Fullbore : MIT-IA and/or MIT-T to 2,500 psi
2.E-Line : Set 4-1/2"x5-1/2" whipstock
3. Service Coil : Mill 3.80" window (if window not possible, mill with rig). Give AOGCC 24hr
notice prior to BOPE test. Test BOPE to 3500 psi. MASP with gas (0.10
psi/ft) to surface is 2,359 psi.
4.Valve Shop : Bleed production, flow and GL lines down to zero and blind flange.
5. Operations : Remove wellhouse and level pad.
Rig Work: (Estimated to start in February 2025)
1. MIRU and test BOPE 250 psi low and 3,500 psi high (MASP 2,359 psi).
2. Mill 3.80” Window (if not done pre-rig).
3. Drill build section: 4.25" OH, ~638' (18 deg DLS planned).
4. Drill production lateral: 4.25" OH, ~2,676' (12 deg DLS planned). Swap to KWF for liner.
5. Run 3-1/2” x 3-1/4” x 2-7/8” L-80 solid liner.
6. Pump primary cement job: 47 bbls, 15.3 ppg Class G 1.24 yield, TOC at TOL*.
7. Only if not able to do with service coil extended perf post rig – Perforate Liner
8. Freeze protect well to a min 2,200' TVD.
9. Close in tree, RDMO.
* Approved alternate plug placement per 20 AAC 25.112(i)
Post Rig Work:
1. Valve Shop : Valve & tree work
2.Slickline : SBHPS, set LTP* (if necessary). Set live GLVs.
3. Service Coil : RPM and Post rig perforate (~200’).
4. Testing : Portable test separator flowback.

Pipe rams sized for running liner. - mgr
Managed Pressure Drilling:
Managed pressure drilling techniques will be employed on this well. The intent is to provide constant bottom hole
pressure by using minimum 8.4 ppg drilling fluid in combination with annular friction losses and applied surface
pressure. Constant BHP will be utilized to reduce pressure fluctuations to help with hole stability. Applying
annular friction and choke pressure also allow use of lighter drilling fluid and minimizes fluid losses and/or
fracturing at the end of the long well bores. A MPD choke for regulating surface pressure and is independent of
the WC choke.
Deployment of the BHA under trapped wellhead pressure will be necessary. Pressure deployment of the BHA will
be accomplished utilizing 3”/3-1/8” (big hole) & 2-3/8” (slim hole) pipe/slip rams (see attached BOP
configurations). The annular preventer will act as a secondary containment during deployment and not as a
stripper.
Operating parameters and fluid densities will be adjusted based on real-time bottom hole pressure measurements
while drilling and shale behavior. The following scenario is expected:
MPD Pressure at the Planned Window (8,728’ MD -8,645' TVD)

Operation Details:
Reservoir Pressure:
The estimated reservoir pressure is expected to be 3,239 psi at 8,800 TVD. (7.1 ppg equivalent).
Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,359 psi (from estimated
reservoir pressure).
Mud Program:
Drilling: Minimum MW of 8.4 ppg KCL with viscosifier for drilling. Managed pressure used to maintain
constant BHP.
Disposal:
All Class l & II non-hazardous and RCRA-exempt drilling and completion fluids will go to GNI at DS 4.
Fluids >1% hydrocarbons or flammables must go to GNI.
Fluids >15% solids by volume must go to GNI.
Fluids with solids that will not pass through 1/4” screen must go to GNI.
Fluids with PH >11 must go to GNI.
Hole Size:
4.25" hole for the entirety of the production hole section.
Liner Program:
3-1/2", 9.3#, 13Cr/Solid: 8,310' MD – 8,720' MD (410' liner)
3-1/4", 6.6#, 13Cr/Solid: 8,720' MD – 9,150' MD (430' liner)
2-7/8", 6.5#, 13Cr/Solid: 9,150' MD – 12,044' MD (2,894' liner)
The primary barrier for this operation: Kill Weight Fluid to provide overbalance as necessary.
A X-over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole.
Well Control:
BOP diagram is attached. MPD and pressure deployment is planned.
Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3,500 psi.
The annular preventer will be tested to 250 psi and 2,500 psi.
1.5 wellbore volumes of KWF will be on location at all times during drilling operations.
20 AAC 25.036 (c)(2)(A)(iv): Waiver Request
. Blind/Shear rams will be utilized in place of pipe rams sized for CTD jointed pipe operations as a
worst-case shut-in scenario (in place of 2-3/8”x3-1/2” VBRs for liner runs and 1” / 1-1/4” CS hydril
pipe rams).
a. Blind/Shear rams are preferred over pipe rams in CTD jointed pipe operations, because liners and
jointed pipe strings for CTD are only ~500-3500’ long and therefore are not suitable killstrings –
having a circulation point of less than ~3500’ MD. The jointed pipe will also be pipe light and would be
shut in below the flow cross. Thus, circulation would not be possible if shut in.
There is not adequate room to add extra BOP rams for this well (see attached tree height diagram):
b. Current Well Tree height is 167.5”.
c. CDR2 max tree height, with six ram BOP, to fit over the well is 163”.
d. CDR3 max tree height, with six ram BOP, to fit over the well is 172”.
e. A six ram BOP stack (to accommodate two extra rams for CTD jointed pipe operations – 2-3/8”x3-1/2”
VBRs for liner runs and 1” / 1-1/4” CS hydril pipe rams), is based off two triples.
Mitigations:
f. The well will be full of KWF prior to running liner or jointed pipe operations.
g. The BHA will be circulated out of hole prior to laying down BHA for jointed pipe operations.
h. The well will be flow checked after laying in KWF, before laying down BHA and before making jointed
pipe.
i. In addition, a X-over shall be made up to a 2 3/8" safety joint including a TIW valve for all tubulars ran
in hole.
j. Primary shut-in standing orders will be to use a safety joint while running 2-3/8” or 3-1/2”x3-1/4”x2-
7/8” solid or slotted liner, 1” or 1-1/4” CS Hydril jointed pipe, and perf guns.The desire is to keep
the same standing orders for all jointed pipe operations and not change shut in techniques in
the middle of jointed pipe operations or from well to well (run safety joint with pre-installed
TIW valve). When closing on a safety joint, 2 sets of pipe/slip rams will be available, above and
below the flow cross providing better well control option.
Directional:
Directional plan attached. Maximum planned hole angle is 108°. Inclination at kick off point is 42°.
Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run.
Distance to nearest property line – 20,300 ft
Distance to nearest well within pool – 750 ft
Logging:
MWD directional, Gamma Ray and Resistivity will be run through the entire open hole section.
Real time bore pressure to aid in MPD and ECD management.
Perforating:
200' perforated post rig – See attached extended perforating procedure.
2" Perf Guns at 6 spf
If post rig extended perforating with service coil is not an option, the well will be perforated with the rig or
post rig under this PTD.
The well will be perforated between the CTD whipstock and TD of the newly drilled CTD well, completely
in the Prudhoe Pool.
Formations: Top of Prudhoe Pool in the parent is 8,464’ MD.

Post-Rig Service Coil Perforating Procedure:
Coiled Tubing
Notes:
Due to the necessary open hole deployment of Extended Perforating jobs, 24-hour crew and WSS
coverage is required.
Note: The well will be killed and monitored before making up the initial perfs guns. This will provide
guidance as to whether the well will be killed by bullheading or circulating bottoms up throughout the
job. If pressure is seen immediately after perforating, it will either be killed by bullheading while POOH
or circulating bottoms up through the same port that opened to shear the firing head.
Coil Tubing
1. MIRU Coiled Tubing Unit and spot ancillary equipment.
2. MU nozzle drift BHA (include SCMT and/or RPM log as needed).
3. RIH to PBTD.
a. Displace well with weighted brine while RIH (minimum 8.4 ppg to be overbalanced).
4. POOH (and RPM log if needed) and lay down BHA.
5. After MU MHA and pull testing the CTC, tag-up on the CT stripper to ensure BHA cannot pull through
the brass upon POOH with guns.
6. There will be no perforations to bullhead kill the well. Well will already be loaded w/ weighted brine or KCl
per previous steps. Re-load well at WSS discretion.
7. At surface, prepare for deployment of TCP guns.
8.Confirm well is dead. Bleed any pressure off to return tank. Kill well w/ KWF, weighted brine as needed
(minimum 8.4 ppg). Maintain continuous hole fill taking returns to tank until lubricator connection is
reestablished. Fluids man-watch must be performed while deploying perf guns to ensure the well
remains killed and there is no excess flow.
9.Pickup safety joint and TIW valve and space out before MU guns.Review well control steps with crew
prior to breaking lubricator connection and commencing makeup of TCP gun string. Once the safety joint
and TIW valve have been spaced out, keep the safety joint/TIW valve readily accessible near the working
platform for quick deployment if necessary.
10. Break lubricator connection at QTS and begin makeup of TCP guns and blanks per schedule below.Max
BHA length per PTD is 500ft. Fluids man-watch must be performed while deploying perf guns to ensure
the well remains killed and there is no excess flow.
a. Perforation details
i.Perf Interval:The well will be perforated between the CTD whipstock and TD of the
newly drilled CTD well, completely in the Prudoe pool.
ii.Perf Length:500’
iii.Gun Length:500’
iv.Weight of Guns (lbs):2300lbs (4.6ppf)
11. MU lubricator and RIH with perf gun and tie-in to coil flag correlation. Pickup and perforate perforation
intervals (TBD). POOH.
a. Note any tubing pressure change in WSR.
12. After perforating, PUH to top of liner or into tubing tail to ensure debris doesn’t fall in on the guns and
stick the BHA.Confirm well is dead and re-kill if necessary before pulling to surface.
13. Pump pipe displacement while POOH.Stop at surface to reconfirm well dead and hole full.
14. Review well control steps with crew prior to breaking lubricator connection and commencing breakdown of
TCP gun string. Standing orders flow chart included with this sundry request. Ensure safety joint and TIW
valve assembly are on-hand before breaking off lubricator to LD gun BHA.
15. Freeze protect well to 2,000’ TVD.
16. RDMO CTU.
