This direction and inclination was projected from the final survey point to TD, which resulted in the following bottom-hole location. Measured Depth: 11955 feet True Vertical Depth: 9040.11 feet 1 Schlumberger Formation Evaluation 8-3/4 inch Intermediate Section: The intermediate section of the well was drilled from 6764 feet to 9312 feet MD in one run. A motor was used for directional control during the run. Resistivity, Gamma Ray, APWD, Density, and Neutron data were supplied in real-time and from memory once the tools were retrieved. The final measured bottom- hole temperature was 157.6 degrees Fahrenheit. 6-1/8 inch Production Section The production lateral section of the well was drilled from 9312 feet to 11955 ft. MD in three runs due to the bits being worn out and having to change the bits. A motor was used for directional control during the run. Directional Resistivity, Gamma Ray, Azimuthal Density, and Neutron data were supplied in real-time and from memory once the tools were retrieved. The final measured bottom-hole temperature was 164.3 degrees Fahrenheit. Innovation Implementing compressed ORION data points in our Real-Time frames when high tier formation evaluation services are requested or high ROPs are anticipated is recommended. ORION data compression techniques will provide excellent data density for all evaluation needs allowing more data channels to be sent uphole and greater log detail to catch fine geological features. Schlumberger Oilfield Services — Drilling & Measurements appreciates the opportunity to provide BP Exploration(Alaska)with MWD and LWD services.

Good luck with getting it in place. I will update the well plan with the new information . Regards, Guy Sent from my iPhone On May 11, 2012, at 5:17 PM, "Ciolkosz, Ryan R" <Ryan.Ciolkosz4 bp.com>wrote: Guy, due to issues with the Kingak shale we increased the mud weight from the planned 10.3 ppg to 10.8 ppg to help stabilize the wellbore. Because we increased the mud weight we are changing our cement strategy from a single slurry 15.8 Class G to two slurrys with 500' of 15.8 ppg Class G and 11 ppg Litecrete to the Top of the 7" Liner. The new cement plan is as follows: Casing Size 7"26#, L-80 Intermediate Liner Basis: Tail: 80' of shoe track+ 500'Annular volume above shoe with 40% excess Lead: From 500' annular volume above shoe to liner top packer with 40% excess in OH and 200' excess above liner top packer Total Cement Volume: Spacer -35 bbls of Viscosified Spacer weighted to -10.9 ppg (Mud Push II) Lead 82 bbls, 461 cuft, 244 sks 11 ppg lb/gal Class G- 1.89 cuft/sk Tail 19 bbls, 106 cuft, 91 sks 15.8 lb/gal Class G- 1.16 cuft/sk Temp BHST 220° F Ryan Ciolkosz Drilling Engineer BP Exploration Alaska Office: (907)564-5977 Cell: (907)244-4357 5/14/2012 SEAN PARNELL, GOVERNOR �ry �y�+ �Dv III LELED D RAA 333 W 7th AVENUE,SUITE 100 A�1► Ll.® EORT !S!1IDE �l.CID=3OMB" ANCHORAGE,ALASKA 99501-3539 PHONE (907)279-1433 FAX (907)276-7542 Ken Allen Engineering Team Leader BP Exploration (Alaska), Inc.

Request: Approval is requested for the P&A of Prudhoe Bay well Z-06 Ivishak and Kuparuk formations and to prove isolation between these reservoirs to satisfy zonal isolation for WAG injection into the Kuparuk formation within a 1/4 mile of Z-06. The abandonment procedures outlined in this sundry application are intended to satisfy isolation requirements for WAG injection into the Kuparuk. Reason for Sidetrack Produce/Inject into Zn2-Zn4 Ivishak reservoir. Abandon Z-06 and Ensure annular isolation above and below Z-06 Kuparuk formation penetration to allow for offset WAG injection into Z-102. Well History Z-06 is an Ivishak producer with original completion in 6/1/88. No RWO or significant wellwork besides addperfs. Well is low oil rate, high WC and uncompetitive. Well has been SI since 5/12/09. Cemented 13-3/8" surface casing with 3720 cuft of 15 ppg Permaforst C cement. 60 bbls returned to surface. No top job. 14.3 ppg LOT. Cemented 9-%" casing with 168 bbls 13.2 ppg G followed by 211 bbls of 15.8 ppg cement, reported 50- 75% returns after cement hit shoe. Did not bump plug and found top of cement inside casing at 9143' MD. With 30%washout and 50% returns, cement top calculated to be at 8259' MD. No LOT recorded. Plan to run USIT log over 9-%"casing during rig sidetrack and do remedial abandonment work for Kuparuk and Ivishak while rig is on well. Down squeeze 13-%"x 9-%" annulus with 15.6 ppg 50 bbls Permafrost C cement. Cemented 7" liner on 5/29/88 with 63 bbls of Class G cement. Job went per plan. Volume was based off of caliper log plus 50% excess. CBL log run on 7" liner shows fair to good cement throughout liner. Other Requests: Given rigfloor height limitations, a MASP < 3000psi, and the fact that the three ram drillingBOP 9 � configuration is preferred to a two ram configuration with a spool, BPXA requests a variance to the provisions of 20 AAC 25.285 (f) (1) regarding the initial testing of the BOPE when existing wellhead or testing equipment prevents the testing of the lowest set of pipe rams. If the lower set of pipe rams cannot be tested during the primary BOP test, that set of rams will be tested at the earliest opportunity during path-forward de-completion work, i.e., after the completion has been pulled from the well. Safety concerns and spacing limitations with the wellhead height and tubing spool preclude us from installing a spacer spool in the BOP stack. Z-06Ai PTD Page 1 3/21/2012 Scope of Work: The sidetrack plan for the Z-06 well includes the following: during pre-rig operations laying cement across the perforations and cutting the 3-1/2" tubing at approximately 9358'. Pull tubing and run USIT log from tubing stub to surface to verify cement between Ivishak and Kuparuk reservoirs • and Kuparuk and Schrader bluff reservoirs. If cement isolation cannot be verified between the Ivishak/Kuparuk and/or Kuparuk/Schrader with the USIT log, then prove shale isolation between reservoirs to satisfy zonal isolation for abandonment of the lower Z-06 wellbore and WAG injection in Z- • 102. • Perforate two sets of perforations 99 ft apart in Kingak/HRZ shale and attempt to establish circulation up to leak off pressure between the two sets of perforations through the 12-1/4" x 9-%" casing annulus. Lack of communication between perforations will be considered evidence of zonal isolation between reservoirs If able to establish circulation, circulate cement between perfs through the annulus. Lay in at least 100' TVD cement plug above perforations to isolate Ivishak and Kuparuk and at least 100' ' TVD plug above Kuparuk to isolate Schrader and Kuparuk reservoirs. (If cement isolation in annulus is confirmed with CBL, then one continuous cement plug will be set from at least 100ft TVD below Kuparuk to at least 100' TVD above the Kuparuk) Whipstock exit from the 9-5/8" casing at - 6700'. A 8-1/2" hole will be drilled to the top of the Sag River where a 7" drilling liner will be run and cemented. A 6-1/8" production hole will be drilled in the Ivishak. Run sliding sleeves and swell packer production liner assembly with liner top packer. Run 4.5"tubing tied into top of production liner top.

Intermediate Hole: Overpressure in the Colville is expected to be 10.0 ppg (3137 psi). Kupurak is expected to be a 9.5 ppg EMW (3206 psi), however, pressures as high as 10.4 ppg EMW (3509 psi)have been encountered in the Kuparuk. Original Z-06 well penetrated the Colville with a 9.7 ppg MW and did not see any formation fluids. B. Production Hole: Ivishak is expected to be at a 8.1 ppg EMW (3764 psi) and Sag river 8.3 ppg EMW (3697psi). II. Lost Circulation/Breathing A. Intermediate Hole: Original Z-06 wellbore experienced lost circulation (1500 bbls) possibly due to the Highland state fault crossing when weighting up to 10.6 ppg MW. Z-06A will be kicking of at—500' MD (-200' TVD) below the Highland state fault. B. Intermediate Hole - One fault crossing is expected in the Kingak above the TJF at 8,300' MD. This fault is not expected to be associated with losses. C. Production Hole - Two fault crossing are planned at 10,090' and 11,350' MD in the Ivishak. Well plan is designed to minimize contact with faults. Ill. Faults Formation Fault MD TVDss Est.
