Re: Duck IslandUnitO01 ae)/(0 Well Renaming Request SCANIJteP Dear Commissioner Foerster, Hilcorp Alaska, LLC (HAK) requests a change to the naming convention of Duck Island Unit wells to remove the unused suffixes at the end of each well name. Well names currently include a forward slash "I" followed by an obsolete bottom hole location designator. HAK would like to retain the well number as well as the "A, B, C...." sidetrack designations but remove the "/suffix". For example, "DUCK IS UNIT SDI 1-09A/L21" would become "DUCK IS UNIT SDI 1-09A". The attached spreadsheet includes original and new names for all Duck Island wells. While performing the review of Duck Island well names, HAK found a single well, "DUCK IS UNIT SDI 4-20/M35" (PTD# 1861730), that should also be modified to include an "A" label to reflect the fact that the well is a sidetrack from the original "DUCK IS UNIT SDI 4-20/T34" (PTD # 1861500). The original wellbore, abandoned 10/13/1986, was sidetracked to a new bottom hole location completed on 9/9/1987. This well appears to be one of the first sidetracks performed at Endicott. While the bottom hole code was changed, no letter was added to reflect the sidetrack. "DUCK IS UNIT SDI 4-20A" is also included on the attached spreadsheet.

To: Tom Maunder - AOGCC Date: January 15, 2009 From: Paul Hanson - BPXA ACT Rotary Drilling Subject: END 4-04 Application for Sundry Approval - P&A for Sidetrack Operations Reference: API # 50-029-21968 Approval is requested for the proposed P&A of Endicott well END 4-04. END 4-04 has been shut in since February 2008. The well has been a water injector since 1990, so the waterflood pattern is thought to be completely swept. A caliper log of the tubing conducted in March 2008 indicated that the tubing was in poor condition, and a leak detection log in July 2008 showed three tubing leaks and two anomalies. The 9-5/8" casing is believed to be in good condition, as the well passed a combo MIT in March, 2008. The proposed P&A is planned to prepare this well for the END4-04A sidetrack - a planned Kekiktuk producer. The END 4-04A sidetrack is scheduled for Doyon 14 around March 15, 2009.. The pre-rig work for this sidetrack is planned to begin as soon as the attached Application for Sundry is approved. Scope Notify the field AOGCC representative with intent to plug and abandon Pre-Rig Work to be Done: 1) Perform MTT/OA 2) PPPOT Tubing and Casing. (last done on 9/27/2008). 3) Function test casing and tubing LDS (last done on 9/27/2008). 4) Pull SSSV if installed, drift and tag fill and dummy off any live GLMs. 5) Perform injectivity test. Monitor and record IA and OA pressures during pumping operation. 6) Full-bore cement squeeze perforations with 15.8 ppg cement slurry. Final cement volume should be determined by injectivity test and PBTD. Minimum cement volume should be sufficient to cover perforations and bring cement to the tubing tail at 13,058' TMD -approximately 600 ft. above the uppermost perforation. Assuming a PBTD of 13999', this requires a minimum volume of 35 BBLS to fill the liner and tubing. Desired volume is 45 BBLS of cement slurry. (Squeeze 5 to 10 BBLS into perfs and leave excess cement in tubing). Cement calculations: ~`~,,., ~„/j • With PBTD of 13,999' -Tubing tail at 13,058' : 35 bbls ~° ~~1"~ • Barrels to squeeze behind pipe: 10.0 bbls Total cement volume : 45 bbls 7) Run wireline drift of tubing and tag TOC. CMIT tubing/IA. 8) Jet cut the tubing at 8,900' MD. 9) Circulate the tubing and IA to 9.1 ppg NaCI brine. Freeze protect tubing and IA to 200' with diesel.

A TTP was set on 03/13/08 and a CMIT-TxIA passed to 2400 psi on 03/14/08. Although wellhead pressure initially bled down, the wellhead pressures were tubing/IA/OA equal to 2600/2600/200 on 03/17/08.

According to pressures manually recorded by our well integrity team, the tubing/inner annulus/outer annulus (TIO) pressures on February 17, ~ 2008 were 2400/1900/200. The IA pressure was bled to 1600 psi and increased to 1850 psi within 30 minutes of bleeding. A TIO plot and wellbore schematic are attached for reference. The well has been reclassified as Under Evaluation and will be added to the Monthly Injection Report. BPXA recognizes that under Rule 7 of the Area Injection Order No. 1 for the Endicott Field, we have an obligation to notify the Commission on the first working day following observations of pressure communication, and this email is intended to satisfy that obligation. Please note that BPXA has an automated system in place that generates a well integrity diagnostic report for many wells, including this one. Following this weekend's observation of pressure communication, BPXA is in the process of reviewing information from the computer system that generates these reports. Initial indications from this automated system, ~ including the attached graph, indicate that pressure communication may have occurred as early as September 22, 2007. (Unlike the manual readings obtained this past weekend, the tubing pressure upon which the attached plot is based, was generated from an automated system). BPXA is establishing an investigation team to evaluate the accuracy of the well integrity diagnostic report as it relates to this well, including further analysis of historical pressures in this well. BPXA will make the results of the investigation available to the Commission once it is completed. «END4-04 TIO.BMP» «4-04.pdf» The plan forward for this well is as follows: 1.

The pre-test pressures were monitored for 30 minutes and observed to be stable and the standard annulus pressure test was then performed. This well passed the MIT and is suitable for continued injection. Summary: I witnessed a successful MIT on BPX's DIU SDI well 4-04 in the Endicott Field.

Well had been placed on MI injection for the first time earlier in the day and was taking little if any MI (not registering on flowmeter). Bleed lAP to 2300 psi. lAP=2600 psi, bleed to 1900 psi. Check tubing hanger void space for pressure. Bled gassy black liquid for approx 20 min, but did bleed off to zero pressure. lAP=3100 psi, bleed to 2000 psi. SIWHP=4000 psi, OAP=0 psi. Plan to bleed tubing pressure down to determine if SSSV holding and hence possibly determine if the communication is above or below the SSSV. Install pressure guage on tubing hanger void space between T seals and primary seal also. Pressure readings in table below. psi Press, psi ...... 2030 .............................

RD HB&R. l J SUMMARY: Well was taking little or no MI injection shortly after being swapped to MI, then tubing-annulus communication was noted. Does not appear to be a tubing obstruction (hydrates) as were later able to pump into well with no problem. Pressure test of inner annnulus indicated pressure loss of 500 psi in 15 min. Tubing hanger seals do not appear to be leaking. SSSV failed to hold pressure during bleed off of tubing. Were unable to isolate leak other than to confirm it is not at tubing hanger. Plan to swap well back to water injection and monitor lAP for communication. Also need to change out SSSV when slickline unit available.

Zone 3C is the primary objective. The completion will be run at the time of drilling and will consist of a simple type assembly. Oneration Execute a rig move to slot 4-04 and rig-up. Vertically drill 17-1/2" hole to 2500 ft. and cement 13-3/8" 68#/ft., NT-80CYHE Buttress casing to surface. Pressure test casing. Install BOPE. Maximum BHP is 4840 psi at 9855 ft. TVDss. Maximum possible surface pressure is 3900 psi based on a full gas column. Drill out casing and 5 ft. of new hole and conduct a formation leak-off test. Vertically drill 12-1/4" hole to 2550 ft., then directionally drill to the intermediate casing point above the Kekiktuk formation. Run and cement 9-5/8" 47#/ft., NT80S and NT95HS, NSCC casing. No abnormal pressures are expected in the 12-1/4" hole section. Pressure test casing. Drill out casing shoe. Drill 8-1/2" hole to TD. Run open hole logs. Run and cement 7" 29#/ft, NT95HS buttress (TKC) liner to TD with approximately 250 ft. of lap in the 9- 5/8" casing. Clean out to float collar. Test casing and lap to 3000 psi. Change over to NaC1 packer fluid. Run CET/CBT/VDL/GR/CCL in 7" liner and in the 9- 5/8" casing to the top of cement behind the 9-5/8" casing. Run gyroscopic survey from PBTD to surface. Perforate well under balance utilizing drill pipe conveyed guns. Fl~mple clean-up. Kill well and complete with a simple com~rm M~bn completion. A sub surface safety valve will be insta!~ below b~rmafrost. Nipple down BOPE. Install tree on wellheadrand release rig. The 13-3/8" x 9-5/8" annulus will be freeze protected with a non-freezing fluid down to 3000 feet once the rig is released. Note: Notify Alaska Oil and Gas Conservation Commission prior to pressure testing casing, production liner, liner lap, and performing MIT.
