ITEM 1a: Classification of Service Wells: Gas Injection, Water Injection, Water-Alternating-Gas Injection, Salt Water Disposal, Water Supply for Injection, Observation, or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. ITEM 4b: TPI (Top of Producing Interval). ITEM 8: The Kelly Bushing elevation in feet above mean low low water. Use same as reference for depth measurements given in other spaces on this form and in any attachments. ITEM 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). ITEM 20: True vertical thickness. ITEM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. ITEM 23: If this well is completed for separate production from more than one interval (multiple completion), so state in item 1, and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval).

C-04A was proposed as a lower zone 1 sidetrack in Northern C-Pad. The rig moved off of the well in July of 1996, but the first test with PBGL was not recorded until early October. The well required a permanent poor boy gas lift installation due to insufficient gas to lift the liquids. The GOR was steadily rising in this well and in February 1998 an STP was run. It revealed several gas entries in the toe section ofthe well. An IBP was set at 11,740' md in March 1998 with the intention to shut off gas production from the last two sets of perforations. The IBP was not successful in decreasing the GOR, thus it was removed and a CIBP was installed at 11,260' md in April 1998. This plug isolated the bottom four perforation intervals. This left only 420' of the original 1,130' of production interval open. As expected, the well suffered low production rates. In 1999, C-36, the poor boy gas lift source well, was planned for sidetrack. Therefore, the CIBP was milled in February 2000 to allow C- 04A to flow independently. Post-CIBP the well produced full time until early 2001 when the well reached MGOR and began to cycle. In June 2003 an RST was run to update the gas picture and identify adperf potential. The June 2003 GOC was identified at -8848' SS or ~ 16' TVD (~ -3' /yr) below the December 1998 GOC. 15' of e-line perforations were added in March of 2004 in an attempt to increase production while maintaining ~ 57' of standoff from the gas. In July a CIBP was set at 10,510' md to isolate all of the original perforations and flow the 03/09/04 adperfs exclusively, except that the well would not flow. An additional 15' of perforations were added in September. Even with PBGL, this well would not flow following the /' adperfs. One last attempt to increase this well's productivity was made in January 2005, but 15' of e- line perforations did not prove successful. Shortly after the perforations were added in January C-04A was shut-in. It remained off production for the better part of 2005 because its twin, C-08, was sidetracked in April. Due to velocity constraints in the flowline, the wells could not flow together. C-08B reached marginal in September and C-04A had its first opportunity to produce. Well tests revealed that there is little remaining value in this wellbore. Milling the CIBP was considered, but not pursued due to the original perforation interval's history of high gas production. REASON FOR SIDETRACK: For most ofthe well's life it has been used as a cycle well. Over the past 12 months the on-time seen by the well has dropped below 10%. This well's twin, C-08, was coil sidetracked in early 2005. Post- sidetrack these wells could not flow together due to velocity constraints in the flowline. C-08B hit marginal in September ofthis year and allowed C-04A to be brought on-line for the first time in six months. Unfortunately, the well did not heal even after being shut-in for an extended period oftime. The GOR has remained above 50k and the well has remained shut-in. Due to the low remaining value of this well, its lack of wellwork options, and its wellbore integrity, this well is recommended for a coil sidetrack to access new reserves. ~e sidetrack is planned on or arlnd June 25.2006.' The sidetrack, C-O, will exit the existing 7" /' liner and land in zone Z4. The existing perforations will be isolated by a CIBP and the primary cement job. The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack is attached for reference.

I. Supervisor State of Alaska Oil and Gas Conservation Commission DATE: March 23, 2001 FROM: Jeff Jones, SUBJECT: Petroleum Inspector Safety Valve Tests PBF/PBU C Pad March 23., 20.0.1' I traveled to Prudhoe Bay Field to witness Safety Valve System tests on BPX's C Pad. Well house inspections were also conducted. Merv Liddelow was the BPX representative in charge of testing, and performed the tests in a professional manner. Twenty-one wells on C-Pad were tested with five failures witnessed. The $SV on well C-04A tripped below 50% of the separator psi, the $SV on well C-07A failed to hold D/P, the pilot on well C-19B was frozen, the pilot on well C-20B failed to trip and the SSV failed to hold D/P. Mr. Liddelow indicated to me that all failures were repaired within 24 hours. I inspected 21 well houses and noted leaking wing valves on wells C-03A, C-13A and C-19B. A hydraulic fluid leak on the SSV control line of well C-05 and a slight crude oil leak from the SSV on well C-25A were also noted. Mr. Liddelow indicated he would have these items corrected. The AOGCC test forms are attached for reference. SUMMARY: I witnessed the SVS tests on twenty-one oil producing wells on C Pad in the Prudhoe Bay Field. 21 wells tested 42 components, 5 failures witnessed, and 11.9% failure rate. 21 well houses inspected.

The target is located in a small fault block which may not effectively communicate with the offset wells. Furthermore the 14N shale is known to be discontinuous in this area. Therefore, the underruns and high GORs found in C-37, C-39, and C-41 should not be present. Instead this well should perform similarly to C-42. C-42 is currently producing at 2400 BOPD with a GOR of 9100 scf/stb. Mud Program: Al0.00 - 10.20 ppg Biozan polymer / KC1 water based mud will be used.

( use 7200 serious mill and do not use 8200 serious mill ) . RIH open ended to 8670' MD' and spot a kick-off plug from 8670' MD up to - 200' above the top of the section ( @ 8325' MD' ). That would require total of 185 sks of cement. Hjowever, this volume could be adjusted after the section is cut. Pull 12 stands, shut in and perform hesitation squeeze. Attempt to achieve a 1000-2000 psi squeeze but do not displace TOC below 100' above section top.

Space out, test the SSSV and circulate with corrosion inhibitor prior to setting packer. Drop the packer setting ball. Pressure the tubing to 4000 psi and set the packer. ( NOTE: The Packer must be set prior to ND BOP and NU Tree because the well is perforated ) Close the SSSV, install a TWC, and test to 1000 psi. Remove BOP's. Install and test the production tree to 5000 psi. Pull the TWC valve. While holding the 1500 psi on the tubing, pressure test the annulus to 3500 psi for 30 minutes. First bleed off the annulus, then the tubing to 0 psi. Open the SSSV and shear the RP on the upper GLM with 2900 psi annulus pressure. Bleed off pressure and freeze protect with diesel to 2200' MD. Set a BPV. Close the SSSV and secure the well. Release rig. Complete appropriate documentation and hand-over to Production.
