Enclosed please find a spreadsheet with a list of wells from Northstar 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, 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.

Subject: NS14 Permit Application for Sidetracking NS14
Dear Mr. Hubert,
NS14 experienced high GOR in the Ivishak production from either gas coning or
communication with nearby gas injectors. As a result, NS14 has been shut-in. It is
planned to abandon the current wellbore in the Ivishak and sidetrack NS14 with a
horizontal lateral at a new location. A Sundry Notice has also been submitted for
abandoning the current wellbore.
Maximum anticipated surface pressure (full column of gas from TD to surface) is 4619
psi. We will be utilizing Nabor's 33e 5000 psi four preventer stack (3 rams and an
annular). The drilling operation will require running 2381' feet of 7° intermediate liner. We
are requesting a variance to the requirement to have two ram preventers to cover the 7"
liner and 2 ram preventers for the 5" DP. We would like to use a variable bore ram on top
that can cover both DP and casing. This would provide one ram and the annular for the 7"
liner and two rams for the DP and does not necessitate changing rams after picking up
the 7" liner. In the event of a well control incident, our standard practice is to immediately
cross-over to DP to allow ram to ram stripping (if required) and we would prefer not to
have to change out rams during ashut-in.
The only close approach for the sidetrack is with the original NS 14 wellbore which will be
abandoned.
NS14 sidetrack will utilize gas detection equipment but is not planned for mudloggers.
Please find attached the NS14 sidetrack Well Plan Summary, directional plan and
proposed completion diagram. If you should have any questions or concerns, please
contact me @ 564-4171.

NS 14 Sidetrack Scope
The original NS 14 completion will be plugged and abandoned due to high GOR possibly from
coning and/or communication with a nearby gas injector. This will be achieved using a full bor~:
squeeze of 9 to10 bbl of Class G, 1s.8 ppg cement while displacing the tubing volume.
The existing s-1/2" X 4-1/2" tubing will be chemically cut at approximately 12,266' MD and pulled.
A bridge plug will be set at approximately 10,234' TMD and a whipstock and milling assembly run
to cut a window from 10,214' to 10231' MD (8,70s' to 8,718' TVD). The original wellbore will be
sidetracked in 8-1/2" hole (opened to 9-1/2") to 12426' MD (Sag Target) and a 7" drilling liner will
be set and cemented. After cementing the 7" liner, 6-1/8" hole will be landed at 90° and continue for
approximately 1,500' in the Ivishak. A 4-1/2" 13 Cr liner will be run and cemented and the liner will
be perforated with tubing conveyed guns. The well will be completed with 4-1/2", 13 Cr Vam Top /
tubing. The new horizontal section will minimize gas coning effects and minimize communication
with the injector -reducing GOR.
Pre-Riq Operations
1. Test 9-5/8" pack-off to 5000 psi.
2. MIT inner annulus to 4200 psi.
3. Through tubing cement squeeze perforations with 15.8 ppg cement slurry. Final
cement volume should be determined by infectivity test. Minimum cement volume
should be sufficient to cover perforations and leave TOC at +/- 12426' TMD. This
is 505' of cement above the PBTD of 12931' and requires a minimum volume of
7.7 BBLS to fill the liner. Desired minimum volume is 9.7 BBLS of cement slurry.
(7.7 BBLS to fill pipe and 2 BBLS into perfs. WOC
4. Run wireline drift tubing and tag TOC. Pressure test tubing to 2000 psi.
5. Run and set plug in XN nipple at 12318'.
6. Chemically cut tubing at 12266' TMD above packer.
7. Install BPV.
Drilling Riq Operation:
1. MIRU.
2. Circulate well clean with sea water.
3. NU BOPE and test to 5000 psi (3500 psi annular).
4. Pull 5-1/2" X 4-1/2" tubing string
5. PU DP. RIH w/ casing scraper to +/-10400'. Test casing to 3500 psi.
6. RIH and set 9-5/8" bridge plug at ~ 10234' TMD. Final setting depth will be
determined by CCL to space out bridge plug for whipstock. The desired top of
window is 10214'. Pressure test bridge plug.
7. Run and set whipstock on top of BP. Mill a window in 9-5/8" casing from +/- 10214
to 10230'.

It will be critical to keep fluid loss very tight during this interval to combat differential sticking on the liner
run. Keeping mud density as low as possible through the upper hole sections and weighting up
concurrently with tightening fluid loss will be critical for drilling through the Kingak and landing in top-of-
Sag.

ANTI-COLLISION ISSUES:
There are no known anti-collision issues with the current well plan. The only close approach potential is with the
existing NS 141ower wellbore that will be abandoned.
WELL CONTROL'
Equipment will be installed that is capable of handling maximum potential surface pressures. (Schematics are on
.file with the AOGCC and MMS.)
/ 5000 psi working pressure pipe rams (2) /
/ Blind/shear rams (VBRs will be available for cut-and-pull decompletion of 4-1/2"x 5-1/2" tubing string).
/ Annular preventer
Based upon the calculations below, BOP equipment will be tested to 5000 psi.
