C-32A Application for Sundry Approval - P&A for Sidetrack Operations
APl # 50-029-21559-01
Approval is requested for the proposed P&A of PBU well C-32A. Well C-32 was unsuccessfully
sidetracked in September 1998 and has since been suspended. Well C-32A targeted the Zone 1 fluvial
deposits and would have been a horizontal completion. During drilling, the well encountered a shale
wedge, causing the well to be steered in attempts to avoid the shale. Further drilling penetrated sands
with anomalous gamma ray readings that were difficult to correlate. Finally, sand alternating shales were
drilled and the well was landed at a TD of 12,268'. Mechanically speaking, the window had been milled
and the well had been drilled to TD, but the pipe and bit became stuck while reaming shales. Once the
pipe was stuck, crude was circulated in an attempt to release the pipe. This proved to be unsuccessful.
The coil was chemical cut at 11,020', and further fishing attempts were also ineffective.
The original parent well, C-32, produced six million barrels of oil from the 14P/13P zones from August
1986 to August 1998. Additionally, perforations were added in a 27P oil lens to extend the life of the well.
At the time of the sidetrack, the parent well was suffering high gas rates and thus a GOR exceeding
marginal. A fault penetrating the well in Zone 2 was suspected to be the source of the gas, thus GSO
operations were not attempted because of the significant risk involving the fault.
The C-32B sidetrack is currently scheduled for Nabors rig 2ES, beginning around September 15,
2002, after the completion of the H-02A sidetrack. The pre-rig work for this sidetrack is planned to begin
as soon as the attached Application for Sundry is approved.
Scope
Pre. Ri; Work:
* Notify the field AOGCC representative with intent to plug and abandon *
1. Rig up slick line, drift and tag tubing to top of fish at - 9,573' MD.
2. PJU E-line. RIH and set EZSV cement retainer in the 4 %" tubing tail.
3. PJU coil tubing unit. RIH to cement retainer, plug and abandon, with 15.8ppg class 'G' cement, the
open hole and fish up into the tubing tail to the cement retainer. Use adequate cement volume to fill
the open hole, including the fish, pl.,qs., squeeze away approximately 10bbls. The estimated minimum
cement volume required is 47bbls. Pull out of retainer and circulate the tubing above the retainer
clean.
4. Drift and tag the top of the cement retainer to confirm clear to required cut depth of approximately
9,275'.
5. Fluid-pack the 4 %" tubing and 9 5~8" x 4 %" annulus to surface. Test the integrity of the cement plug
and the 9 5/8" casing to 3000psi for 30 minutes./' /
6. R/U E-line. RIH with Chemical cutter and cut the 4 W' tubing at -9,275' MD, in the middle of the joint
between the Seal assembly and the sliding sleeve.
7. Displace the well to clean seawater by circulating down the tubing through the tubing cut. Continue to
circulate until clean seawater returns to surface. Freeze protect top 2200' MD with diesel.
8. Test the 9 5~8" pack-off and tubing hanger seals to 5000psi for 30 minutes. Function all Lock Down
Screws, repair or replace as needed.

T
9. Bleed casing and annulus pressures to zero.
10. Set a BPV in the tubing hanger. Secure well.
11. If necessary, level the pad. Please provide total well preparation cost on the handover form.

Re:
Well C-32a Suspension
On Sept. 22, 1998 a report was submitted to AOGCC describing the fish left
in the well. Opportunities for further use of this wellbore are still being
evaluated but not yet resolved. We are therefore asking that C-32a be placed
on suspended status pending development of a plan for future utilization of the
well.

further 200 - 300 ft MD in polygon to delineate top of Kavild ratty sand. Geologist seeing oil in
samples but this may be affected by residual oil from freeing stuck pipe earlier.

Well C-32a Fishing Operation
The ooil drilling unit, DSINordic 1, was released from C-32a at 09:00
ho,urn today. This letter and accompanying data are being submitted
to ~nform you of the current status of operations on C-32a and to ask
for clarification on what further may be needed by AOGCC at this time.
The sidetrack, C-32a, had reached a depth of 12,268' MD when the
BHA became stuck on a wiper trip at 11,117' MD. Fishing operations
were successful in moving the fish downhole some 240 ft and back to
the original stuck point numerous times but with no progress above
11,117'. Failure of a fishing neck o,n 9/21198 left the top of the fishing
assembly at a d,epth of 9,573' MD, reside the 7" liner. The position of
the fish and fishing assembly are indicated on the attached schematic.
A detailed description of equipment currently in the hole is also
attached.
Current plans are to drill and complete the sidetrack of J-15a, organize
new fishing equipment, and return to continue fishing operations on C-
32a in about 10-14 days.
C-32a was left with overbalance drilling fluid to approx. 1700 ff and
$0% MeOH freeze protection to surface, The full tree remains in place
and the flowline is connected and freeze protected, The well is stable
with zero surface pressure,

D~ar Mr. Stagg:
Enclosed is the approved application for permit to redrill the above referenced well.
The permit to redrill does not exempt you from obtaining additional permits required by law from
other governmental agencies, and does not authorize conducting drilling operations until all other
required permitting determinations are made.
Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25 035.
Sufficient notice (approximately 24 hours) must be given to allow a representative of the
Commission to witness a test of BOPE installed prior to drilling new hole. Notice may be given
by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

C-32A Sidetrack
Summary of Operations:
C-32 is a poor cycle performer with fault related high GOR. The sidetrack, C-32A, will target
Zone 1(14P-13P) reserves.
This sidetrack will be conducted in two phases.
Phase 1: Lay abandonment cement and set whipstock: Planned for 8119/98.
C-32 will be tested for tubing integrity, drifted for the whipstock and a Kinley caliper will be
run to evaluate liner and tubing condition.
Existing perforations will be abandoned with approx. 20 bbls cement. Abandonment
cement will be downsqueezed past a mechanical whipstock set at approx. 10,087'.
Abandonment cement will be pressure tested to 1500 psi with AOGCC witness. This
procedure is described in more detail in the Form 10-403.
Phase 2: Mill Window and Drill Directional Hole: Planned for 911198.
Directional drilling coil tubing equipment will be rigged up and utilized to mill the
window and drill the directional hole as per attached plan.
Mud Program: - Phase 1: Seawater
- Phase 2: FIo-Pro (8.8 - 8.9 ppg)
Casing Program:
- 2 7/8", 6.16#, L-80, ST-L liner will be run from TD to approx. 9,373' MD and cemented with
approx. 25 bbls. cement. The well will then be perforated with coil tubing conveyed guns.
Well Control: - BOP diagram is attached.
- Pipe rams, blind rams and the CT pack off will be pressure tested to 400 psi and to 4000 psi.
- The annular preventer will be tested to 400 psi and 2000 psi.
Directional - See attachments.
- Kick Off: 10,087' MD (8,706' TVD ss)
- TD: 12,480' MD (8,919' TVD ss)
- Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run.
Logging · A Gamma Ray log will be run over all of the open hole section.
· Memory CNL will be run in the 2 7/8" liner.
