Re: 18 -08A Sundry Approval
Sundry approval is requested to abandon existing perforations on well 18 -08B in preparation for a Coiled
Tubing Drilling Sidetrack. Well 18 -08A is a February 1998 horizontal rotary sidetrack drilled and completed in
Zone 1A with 960' of perfs. The initial production rates were —2300 bopd with 3.3 MMscfd at 1430 GOR, but the
gas rate sharply rose to 35 -40 MMscfd within months. In Nov 1998 the well reached 20,000 GOR and began
cycling. It cycled with decreasing on time for the next few years. A CIBP was set on 2/27/02 to isolate the
second half of the lateral and resulted in shutting off —12 MMscfd gas. The well continued to cycle with declining
oil rates. 30' of perforations were added in Zone 1B near the heel (10042- 10072') in Feb 2005. Because both
the oil and the gas rates increased, the well continued to cycle with decreasing on time. In hopes of regaining oil
rate, the CIBP was milled on 7/17/07. Unfortunately, the oil and gas rates dropped, and the well was shut in for
high GOR within a month. It did not exhibit recharge when POP'ed after long shut -in periods in 2008 and 2009.
18 -08A has remained a long term shut -in for high GOR since July 2009.
Reason for Sidetrack: 18 -08A is no longer a competitive well due to high GOR and has no remaining wellwork
options. The proposed sidetrack will access —50 acre drainage area in western DS 18, north of the Mid - field
Graben.
The well is in sound mechanical condition. It passed an MIT -IA to 3000 psi (December 2010) and the MIT -OA
passed to 2000 psi (December 2010). A tubing ca rper was ran (December 2010) from 10,106' to surface and
found the tubing to be in good condition with a maximum recorded wall penetration of 21 %. The calliper
indicates the tubing is slightly cork - screwed from above GLM #4 at —9,200' to the the KOP at —2,875'. The
PPPOT -T passed to 5000 psi (November 2010) and the PPPOT -IC failed to 3500 psi (July 2006), but the well is
still considered operable since there is a passing MIT -IA.
The sidetrack, 18 -08B, is scheduled to be drilled by Nordic 2 starting on February 15 2012 targeting Ivishak ✓
Zone 1A/1 B. The pre rig work includes setting a whipstock with e-line. The coiled tubing drilling rig Nordic 2 will
then mill the window in Z4, followed by landing and drilling the planned 3,200' lateral in Zn 1A/1B lateral via 12
DLS. The well will be completed with 3 -1/4" x 2 -7/8" solid, cemented, and perforated liner. The following
describes the planned work. A schematic diagram of the proposed sidetrack is attached for reference.

BOP test Doyon 9
co - ps'- 18
January 19; I traveled to ARCO's DS-18 to witness a BOP test on Doyon 9. We
started testingj but the choke manifold valves wouldn't hold so the manifold was
flushed and the valves serviced. The TIW valve on the floor was not bubble tight
so it was failed. Because of the odd size tree and the distance between the tubing
hanger and the bottom set of pipe rams we were unable to test them and the kelly
valves. They will test them when they pull the tubing, repair the TIW valve and fax
over the results. Doyon 9 is a fairly old rig by slope standards and I was
impressed by the professional attitude of the crews. The BOP test occurred
across shift change-out without a bump, and although they just had a rig move the
rig was clean and orderly.
SUMMARY: ! witnessed a BOP test on Doyon 9. 26 components 1 failure

Dear Mr. Stoltz:
Enclosed is the approved application for permit to redrill the above referenced well.
The permit to redrili 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.
Bloxvout prevention equipment (BOPE) must be tested in accordance ~vith 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 mav be given
bv contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

18-06A Short Well Summary
18-08 History
18-08 was originally drilled in April 1986. It is a vertical well completion in Zone lB and lA with 38 feet of
perforations. Initial production was 2000 BOPD. In January 1987, half strength mud acid was pumped to
improve productivity. Shortly afterwards GOR began to rise. A PITS log in October 1987 showed a
channel up to the GOC. By March 1988, the well reached an uncompetitive GOR. April 1988 brought a
GSO squeeze behind the pipe, sealing off the channel. The well returned to production at 1500 BOPD
and solution GOR and after a few months GOR began to slowly rise. The well reached MGOR in 1990
and has been cycle produced since then. YTD, the well has been on-line 67% of the time, averaging 720
BOPD with a GOR of 18,600. Cumulative oil production is 3,560 MBO.
Doyon Rig 9 may move to DS 18-08A on/about January 15, 1998 following the completion of Well 18-06A.
The drilling objective of well 18-08A is to mill through 7-5/8" casing via whipstock into Zone 4, and
directionally drill this sidetrack well down to a single 1,250' horizontal target in the remaining L. Romeo
reserves trapped along the down-thrown side of a normal fault.
Pre-Rig Operations:
The objective of the pre-rig work is to ascertain the condition of the 3 W' tubing and 7 5/8" casing
presently in the hole; P & A all open perforations; chemically cut the 3 ~,~" tubing; test the 7 5/8" pack off.
1. Notify AOGCC of initiation prior to commencing any P&A operations.
2. NU on Well. Bullhead seawater down tubing to kill well and verify injectivity. Report injectivity to ODE.
3. Make GR/JB run on 31/~'' tubing.
4. Pressure test 9 5/8" annulus to 3000 psi for 30 min to check for casing integrity and tubing integrity to
packer. If pressure test fails, set plug in tubing and pressure test to 2000 psi for 30 min. Call ODE if
there are any problems.
5. Bullhead 88 sks. (18 bbls.) of class G, 15.8 ppg cement down tu,b, ing, and displa?.~o place TOC @
100' above top perf. Rig operations will set a bridge plug @ 955~,~JV~.¢["o ~~liii'~)nal barrier.
