The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor.

This well was intended to trial a piece of new technology. This new technology was meant to replace DPC perforation and gravel packing across the Kuparuk reservoir. A deployment failure of the new technology occurred during the installation of the well. This failure has resulted in the P&A of the 7" production casing across the Kuprauk interval. To regain this Kuparuk interval an EZSV was set above the reservoir interval and the /' 7" casing was cemented to above the Schrader Ma sand. A whipstock was then set on the EZSV and a window cut in the 7" to facilitate a 6- Ya" sidetrack to redrill the productive interval. The sidetrack KOP was planned just below the base of the HRZ to minimize footage between the top of the liner top packer and the top of the Kuparuk reservoir. This exit point, just below the base HRZ was viewed to be a good exit point based on previous hole conditions incurred when drilling and completing the original penetration. Mik Triolo, ODE, contacted Winton Aubert, AOGCC at 11 :30 AM, 2/12/2005, and/ received verbal approval to deviate from original Permit to Drill; ie. Plugging back & abandoning the 7" casing below 7,016', then sidetracking through 7" casing to complete through the Kuparuk C4; setting and cementing a 4.5" Liner. Mik Triolo, / ODE, contacted Winton Aubert, AOGCC again on 2/14/05 to discuss further complications with the KOP as discussed below. More time was allotted to turn in the Sundry application due to the possibility of needing to sidetrack higher up within the 7" casing if this window was not able to be saved. Further verbal discussions have been held to provide regular updates prior to this application being submitted. Work Conducted To Date: 1. EZSV was set @ 7,016' MD. 2 stage cement job was pumped through the EZSV such that the lead cement covered the Schrader Ma and the Tail cement covered the Kuparuk and HRZ. /' Whipstock was set on the EZSV and the window was milled in the 7" casing TOW: 6,998' MD, BOW: 7,010' MD. / Upon finishing the window milling just prior to conducting the standard mill dressing run, a pack-off was incurred. Upon further circulation it was realized that the HRZ/Kalubik shale had destabilized and was running. The milling assembly was pulled out of the hole and a cleanout assembly was run to go outside the window and clean up the open hole and weight up the mud from 10.1 to 10.7 ppg. The cleanout was successful and the weight up seemed to help stabilize the hole. A BHA was picked up, the ST hole was drilled to TD as per the attached directional survey. A cleanout trip was performed and the BHA was pulled out of the hole and UD A 4-%" liner was picked up and RIH to the top of the window. The first attempt to get the liner to TD ended at 7,020' / MD, the second attempt ended at 7,002' MD. This operation has been aborted and the liner is currently being pulled out of the hole. 2. 3. 4. 5. Plan Forward Operations (as discussed with Winton on 2114/04): 1. Finish POOH and UD the 4-112" liner. 2. PU cleanout BHA and RIH and clean out the hole and possibly increase the MW to 11.1 ppg if the shales are running. 3. Try to rerun the liner. If successful, cement the liner in place. Test ZXP packer and displace over to seawater 4. LD DP and liner running assembly. 5. Run USIT in the 7" and 4-112" liner 6. Run completion and sting into liner tieback sleeve and set production packer 7. Freeze protect and RD / Release Nabors 7ES /1 Z-103i Application for Sundry '1' "... e e Work Conducted After Discussion: 1. The 4-%" liner was pulled out of the hole and it was noticed that the liner shoe had sustained significant wear marks /' from the window. Thus, it was decided to make a window dressing run and attempt to clean up the open hole after dressing the window during the same trip. 2. Multiple hours were spent working the window area with the mills. Multiple attempts were made to work past the ledge below the window with no success. Just prior to the trip out of the hole with the milling assembly, a dry run was conducted through the window with the milling assembly. The milling assembly would not go through the window without rotation. Upon pulling the milling assembly from the hole, it was realized that the starter mill was -W' / undergauge, indicating that the mills had done significant work to the window area. Therefore the decision was made to attempt to run the 4-%" liner with a bent joint to possibly index past both the window and the ledge just below the window rather then attempt to get a bit through the window to clean up the ledge. / 3. The liner was run past the window but could not get past the ledge. It was pulled out of the hole and laid down. 4. It was decided to make one last attempt to save this window by utilizing a directional assembly to clean up the ledge. The liner was successful in getting by the window, but not the ledge. The BHA was able to get through the window with slight rotation. Once past the window, the BHA stacked out on the ledge. Several attempts were made to work by the ledge, without success, eventually the BHA sidetracked off of the ledge. The hole was redrilled and cleaned up very well. The BHA was POOH. 5. Another liner was picked up and RIH to TD and cemented in place. // 6. A bond log was run both in the 7" and 4- 112" casing, both of which showing adequate bond. 7. The completion is being run as per the original Permit today and the rig should release from the well later on tonight.

Job 9: Case & Cement Production Hole/Run USIT Hazards and Contingencies ~ The interval is planned to be cemented with a lead and tail slurry. The lead slurry will cover from 500' above the Kuparuk to 500' above the Schrader Ma and the tail will cover from the shoe to 500' above the top of Kuparuk interval. > A casing running program will be jointly issued by the ODE and Drilling Supervisor detailing circulating points and running speed. In addition a Steel Seal pill composed may be placed across the Schrader and Ugnu to help arrest mud dehydration if losses were experienced while drilling this interval. ~ Ensure a minimum hydrostatic equivalent of 10.1 ppg on the HRZ during pumping of cement pre flushes/chemical washes. Losses of hole integrity and packing off has resulted from a reduction in hydrostatic pressure while pumping spacers and flushes. ~ Ensure the lower production cement has reached at least a 70BC thickening value prior to freeze protecting. Pump approximately annulus volume +10% prior to freeze protecting. After freeze protecting the 7" x 9-5/8" casing outer annulus with 62 bbls of heated diesel (2500' MD, 2442'TVD), the hydrostatic pressure will be 7.6 ppg vs 8.6 ppg EMW of the formation pressure immediately below the shoe. Ensure a double-barrier at the surface on the annulus exists until the cement has set up for at least 12 hours. Trapped annulus pressure may be present after pumping the dead crude as the hydrostatic pressure of the mud and crude could be 140 psi underbalance to the open hole. ~ A cement bond log (USIT) will be run to confirm injection zone isolation. This will be done with the rig prior to running the completion. Send results of USIT log into Anchorage office as soon as possible for evaluation.

Z-103 Well Summary of Drillinq Hazards POST THIS NOTICE IN THE DOGHOUSE Surface Hole Section: · Gas hydrates may be encountered near the base of the Permafrost at 1929' MD and near the TD hole section as well. · Gravel beds below the Permafrost will tend to slough in when aerated (hydrate cut) mud is being circulated out. Ensure adequate mud viscosity is maintained to avoid stuck pipe situations. Production Hole Section: · A majority of the V-Pad development wells will have "kick tolerances" in the 25-45 bbl. A heightened awareness of kick detection, pre-job planning and trip tank calibration will be essential while drilling/tripping the intermediate/production intervals. · The production hole section will be drilled with a recommended mud weight of 10.1 ppg to ensure shale stability in the HRZ shale and to cover the Kuparuk B/A 9.8 ppg pore pressure. · Tight hole, hole packing-off, and lost returns have been encountered in previous wells on this pad. Pipe sticking tendency is possible if the HRZ shale gives problems. Back reaming at connections and good hole cleaning practices and close monitoring of PWD data will contribute to favorable hole conditions. · Z-103 is expected to cross one fault in the intermediate hole section. The approximate location of the fault is 3450' +/- 100' and has an estimated throw of 170'. Lost circulation is considered a minimum risk.

" . . Bob, There was a error on the Z-103 injector drilling permit application in regards to nearby wells at the Kuparuk level which is part of the Area Of Review (AOR) process. I've had our subsurface group produce a plan view map at the Kuparuk level to identify any of the penetrations and added a circle at 1/4 mile radius from the proposed Z-103 at top Kuparuk (attached). We have also performed an investigation at the Schrader level and find no Schrader wells within 1/4 mile. Using this information we have found: 1. The nearest well Kuparuk well is the Z-100 producer at 2200' to the north 2. There are 3 Ivishak wells within 1/4 mile of the point where Z-103 penetrates the Kuparuk. Details are: Z-39 at 790' east, calculated TOC at 3762'MD ~ðO ~i' ,/ 2-03 at 1160' south-southeast, calculated TOC at 3200'MD Z-11 at 1280' southwest, calculated TOC at 4500'MD l Cfo 071- ,/ Please find attached a plan view drawing to better clarify this information. «Slide1.ZIP» Regards, Jim Smith GPB ODE 564-5773 Content-Description: Slide1.ZIP Content-Type: application/x -zip-compressed Content-Encoding: base64 lofl 11/18/20041:10 PM R~Z-103 1250ft. Offset well scan Question on Information Required ,\ --. . . Neil; Yes, we want a listing of all wells that penetrate the Kuparuk Fm. within a 1/4 mile radius of the Z-103i well's pentetration of the Kuparuk Fm. This is part of the UIC (underground injection control) program which we administrate for the EPA. Any well that penetrates a formation within a 1/4 mile of an injection well completed in that same formation (1 03i is injecting in the Kuparuk Formation, any well that penetrates the Kuparuk Formation within a 1/4 mile of the 103i injection interval, in this case we'll use the 103i top ofKuparuk) needs to be evaluated for mechanical integrity, in this case it will mean evaluating Kuparuk isolation (cement). The ajacent wells are considered likely out of zone conduits for 103i injection fluids. The adjacent wells regardless of completion interval require evaluation. Attached is a newsletter containing a complete description of this process, for reasons you understand I'm sure, it's in everyones interest we do this proceedure correctly. I'd appreciate your circulating Tom's article to everyone you know (including Kip) who is involved with this. Do I have a complete listing of wells that penetrate the Kuparuk Formation within a 1/4 mile ofthe Z-103i well's penetration of the Kuparuk Formation? BobC Magee, D Neil wrote: Bob, I was discussing this with Kip Cerevny here at BP just after I sent this note and he bought up a point for clarification. The Z-013i injection well is a Kuparuk penetration. The wells we have identified on the scan are Ivishak penetrations. There were no Kuparuk intervals "open" in these nearby wells. Is this the information you're looking for, any penetration within a 1/4 mile of the production zone regardless if the well is injecting/producing in the same zone?
