whipstock assembly and stab onto well and PT. RIH. PUH through GLM #1 while logging for tie in to
GR/CCL dated 11/24/94. RIH, passing through tight spot in tubing tail (9390'-9409') without problems.
PUH and log 3 collars below and above 10,307' to verify on depth (CCL to top of whipstock is 13'). RIH to
10,380' and attempt to set whipstock. Unable to set whipstock, out of desired orientation window.
Continue to make attempts to set whipstock by varying speeds while RIH and PUH. Closest orientation is
roughly 55 degrees left of the high side one joint above (10,270' to 10,312') desired whipstock set point of
10,320' (top of joint located at 10,312'). Call Well Operations Team Leader to discuss next plan of attack.
Receive approval from Anchorage Drilling Engineer to set whipstock at 55 degrees left of the high side in
the joint from (10,270' to 10,312') rather than risk getting stuck in the damaged tubing tail. PUH to 10,267'
- top of whipstock is at 10,280', RA tag is at 10,288.9'. Whipstock is oriented 44 degrees left of highside.
Unable to set whipstock - short in the tool string. SWS to attempt switching modules in the logging unit
prior to attempting to POH and through the TT. New module produces similar results, unable to set
whipstock. POH. Able to pass through tight spot at TT from 9390' to 9409' with no problems. At surface -
lay down lubricator and examine tool string. Found that some portions of the tool string were flooded. Call
to SWS shop for replacement parts.

pumped 5 bbls straight cement followed by 25 bbls cement with aggregate followed by 6 bbls straight
cement. At 25 bbls away (cement covering perfs) noted first sign of pressure build up. Continued
pumping cement with choke closed until 34 bbls cement out nozzle, WHP - 200 psig. Open choke and
maintain 200 psig until remaining cement out nozzle, PUH to safe. Shut down, hesitate 30 min. Bump
pressure up to 600 psig. Hesitate 30 min. Bump pressure up to 1000 psig. Hesitate 15 min. Bump
pressure back up to 1000 psig - good squeeze. Bleed pressure back to 200 psig. RIH contaminating
with Biozan. Found stringer/bridge at 9818'. Worked down to 9848' encountering harder cement.
Elected to abort further attempt to contaminate deeper. POH.
Based on hard cement depth, approx. 9 bbls. cement (470') remains on top of whipstock, leaving 25
bbls below whipstock covering perfs and approx. 2 bbls into perfs.

Well E-24A Prep for CT Sidetrack
Well E-24a is scheduled for a through tubing sidetrack to be drilled with
coiled tubing. The following summarizes the procedure required to prepare E-
24a for sidetracking and is submitted as an attachment to Form 10-403. A
schematic diagram of this proposed completion is attached.
1. A Tubing Integrity Test, whipstock drift and Kinley caliper log are
scheduled to be done.
2. E-Line will set a mechanical whipstock at 10340' MD.
$. Service coil will squeeze approx. 20 bbls cement past the whipstock to
shut off existing perfs.
4. Service coil will then be used to mill the window. Service coil BOPE will
be pressure/function tested with AOGCC witness prior to milling.
Step 3 is scheduled for approx. June 14, and step 4 is scheduled for June 15,
2000, pending AOGCC approval.

COMMENTS ·
This survey was run to assess the condition of the tubing with respect to corrosive and mechanical
damages. The caliper recordings indicate that the 4.5" tubing is mostly in good to fair condition, with
maximum corrosive penetrations in excess of 40% wall recorded in only 6 joints. No corrosive penetrations
in excess of 50% wall are recorded throughout the interval logged. The interval of most severe corrosive
damage recorded ( 30% - 50% wall thickness) runs between joints 134 and 190, from 5,400' to 7,600'. The
damage appears in the form of isolated pits, tending to form in a line on the Iow side of the pipe. The
distribution of the damage recorded throughout the tubing string is illustrated in the Caliper Overview page of
this report.
What appears to be a "slot" milled completely through the tubing wall, approximately 3.125" wide and 4.7'
long is recorded at the very bottom of the tubing tail, through the Wire Line Entry Guide. Tool off-center
motion through this interval indicates that the tubing is stabbed into the liner tie-back sleeve at an angle, with
the "slot" appearing near the Iow side of the pipe, which also appears to be the outside of the "bend" between
the tubing tail and tie-back sleeve. A cross-sectional drawing and 3D picture of this interval is included in the
report.
The 5" liner appears to be in good condition with no penetrations in excess of 12% wall thickness recorded.
No significant ID restrictions or areas of significant cross-sectional wall loss are recorded throughout the
interval logged.

BOPE Test- Doyon 14
BPX - PBU - E-23A
Prudhoe Bay Field
Wednesday, November 9, 1994: I traveled this date to BPX's PBU E pad and
witnessed the BOPE test on well E-24A being drilled by Doyon rig 14.
As the attached AOGCC BOPE Test Report shows there was 1 failure. The lower
kelly valve leaked. This was changed and tested OK.
The location was clean and all extra drilling equipment was stored properly. The rig
was clean and all equipment seemed to be in good working order.
Summary: I witnessed the BOPE test on Doyon RIG 14 - test time 2.5 hours - 1
failure.

Perforations Cement plug
BPX well # E-24
Prudhoe Bay Field
PTD # 940-122
Monday, October 10, 1994: I traveled to BPX E pad to witness the verification of
placement of the cement plug at the perforations in well # 24.
When I arrived the rig was just tripping in the hole and was running late due to problems
setting the 9 5/8 packoff. I was informed it would be approximately 0200 hours to bottom.
Tuesday, October 11, 1994: At 0230 hrs the rig tagged cement at 9573' RKB the mud
motor was started and they milled down to 9587' RKB where the cement seemed alot
firmer. The motor was stopped and 15000 K was set down with out the appearance of
settling in. When the string was picked up it was smooth giving all indications of a solid,
setup cement plug. The rig then prepared to drill down to the window that had been
previously cut at 9839' RKB.
SUMMARY: I witnessed the verification of placement of the cement plug at the
perforations in BPX well #E-24 in the Prudhoe Bay field.

Dear Mr Clark:
Enclosed is the approved application for permit to re-drill the above referenced well.
The permit to re-drill does not exempt you from obtaining additional permits required by law
from other governmental agencies, and does not authorize conducting re-drilling operations
until all other required permitting determinations are made.
Blowout prevention equipment (BOPE) must be tested in accordadnce 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 a new hole. Notice may be given
by contacting the Commission's petroleum field inspector on the North Slope pager at 659-3607.
