When entry is made into the well to replace the fluids, metal shavings are reported in the "cuttings" while circulating at 11000'. After tagging at 16254', the shakers are reported to be blinding. As circulation continues, the metal amount drops off but is still reported as "10%". Was any analysis done to identify the source of the metal shavings? No analysis was done to determine source of metal shavings. The BHA use to trip to TD included a full gauge string mill. This is the same string reamer used for window milling, located behind the starter mill. We ran this to drift the 11-314" prior to tripping in hole with the CIBP. The metal shavings were assumed to be from the 11-3/4" casing, generated by rotating the string mill while displacing out the MOBM. -^his was unanticipated -the string mill should not have worn casing. We believe the string mill reduced the casing wall thickness while circulating rotating at 16,254' and (reciprocating over a stand), for ~24 hours. This is where we believe the casing failed when attempting to pressure test to 4000 psi. 2. During the attempted casing test, it appears that the casing burst. 4000 psi is only - 60% of the published burst for the 11-3/4" pipe. Using an RTTS the casing was subsequently successfully tested to 3022 psi above 15203'. A CIBP was set at 15065' and the casing successfully tested to 2000 psi. What is the basis of the differing test pressures? After recognizing we impacted the 11-314" casing with string mill rotation, we ciid not want to unduly stress the 11- 3/4" with any more pressure than needed for well control to drill ahead. Fail another 4000 psi pressure test could have resulted in running a scab liner. This would have had significant impacts on circulating hydraulics (ECD) given the ID reduction. We therefore tested to 3000 psi, which is greater than the required casing pressure test to 50% of the working pressure of the BOPS. The 2000 psi test was a test of the CIBP, not a casing test. The well bore has recently passed another test to 2,800 psi with 11 ppg mud after cementing the 8-5/8" drilling liner in place. 3/20/2009 Page 2 of 2 3. What were the results of the USIT run on 1/29/09? The USIT was logged from -500' below the planned CIBP setting depth to surface. The log showed the 11-3/4" to have some casing wear, primarily from all the rotations made during the fir:~t attempt at drilling NS33. There is clearly more casing wear at -11,000' md, the string mill depth while rotating/c:irculating out the MOBM for 4.5 hours. The average wall thickness is well within new specs, but when isolating the minimum wall thickness (as expected) there is a wear pattern on the low side of the casing. As mentionec previously, the 11,000' interval has the most wear on the low side. We are looking at options to scab over this arE~a. One possibility is extending the current (planned) 6-5/8" scab over this interval. 4. What operations are currently underway? We are currently in the hole with a dump iron BHA circulating in LCM to plug ,~ lost circulation interval below the 8- 5/8" shoe. We were unsuccessful at getting the 8-5/8" liner to bottom. The liner shoe is -23,540' and (Kuparuk D) and openhole TD is at 24,150' and (Miluveach shale), placing the shoe 610' offi bottom. We are experiencing losses with pressures exceeding --13 ppg, most probably thru a fault at base of Kuparuk/Miluveach top. After getting losses under control, with either LCM or cement, we plan to trip for the drilling BHA to drill up the MiluveachlKingak to TSAG. Ken Allen has ordered a string of 9-5/8" in the event we have to cover up the 11-3/4" pipe, due to pipe wear. We have enough pipe to scab back to surface if necessary. We will wait until openhole drilling is completed before scabbing back to prevent ECD constraints during planned drilling operations. A new USIT may be run to review casing wear after the majority of drilling has been completed to confirm if the casing is a concern for well bore integrity. We're planning on an IA of the completed welt that is good to 4200 i~si -we're intending on assuring enough steel is available to provide for that, for life of well. Thanks in advance. I look forward to your reply.

Estimated Pre-Rig Start: Estimated Spud Date: Ken Allen Operations Drilling Engineer 907.564.4366 01 /01 /08 01 /15/08 NS33 Application for Sundry r ~ by M" To: Tom Maunder - AOGCC Date: October 30, 2008 From: Ken Allen - BP ACT Rotary Drilling Subject: NS33 Application for Sundry Approval - P&A for Sidetrack Operations Approval is requested for the proposed P&A of Northstar well NS33. This conventional well is currently suspended due to hole stability problems encountered above the reservoir in 2007. The well never drilled to the production zone and is providing zero production or value to the field as it currently sits. In April 2007 hole stability problems were encountered while drilling in the Colville formation on NS33. The open hole below the 11-3/4" casing shoe was never fully stabilized while drilling or in subsequent clean out runs. An inadvertent sidetrack was also performed while attempting to drill this section to TD. An attempt was made to run a liner string over this unstable interval, but it was not possible to run it farther than 500' past the current 11-3/4" casing shoe. The liner was then pulled out of the hole and further clean out runs were attempted, but deteriorating hole conditions along with seasonal drilling restriction forced a suspension of the well bore. The plan is to abandon the lower portion of the 11-3/4" casing that has been previously plugged and abandoned through an EZSV Cement Retainer set at 16,415' MD. 274 BBLS of Cement was squeezed below the retainer and 39 BBLS was placed on top of the retainer. Two schematics and an operations summary have been attached to assist in explaining the previous and proposed work for this Sundry application. The proposed new sidetrack will target the Ivishak formation while attempting to drill around the previous problem area. A new Permit to Drill Application will be submitted in the near future designating the new well bore as NS33A. The NS33A sidetrack is currently scheduled for Nabors 33E beginning around 01/15/08. The pre- rig work for this sidetrack will be priority scheduled immediately after the Application for Sundry is approved.

I have updated the Summary of operations in the attached document (Version 2.0). If this is acceptable I would like to update your package with the following document. The only change from your current package is deleting the step "finishing testing the lower rams". All rams should be able to be tested before pulling the Kill Sting. You are correct about the BOPE test to 5000 psi. I have the test documented as "Nipple up and test BOPE (250/5000 psi, Hydrill 3500psi)". Please let me know if this is acceptable or you prefer Sondra to send over a new package hardcopy. Thank you, Ken Allen Drilling Engineer Northstar Mobile: 907.748.3907 Office: 907.564.4366 e-mail: Kenneth.Allen@BP.com From: Maunder, Thomas E (DOA) [mailto:tom.maunder@alaska.gov] Sent: Friday, November 07, 2008 2:54 PM To: Allen, Kenneth W Cc: Kara, Danny T Subject: NS33 (206-138) Ken, I am reviewing the sundry to re-enter this suspended well and effect the abandonment. You have included a step to test the lower pipe rams after pulling the kill string. I believe the MASP for Northstar wells is > 3000 psi and note that you plan to test the BOP to 5000 psi. Does the same height conflict exist under the lower pipe rams as with the rigs at Prudhoe? I am sort of surprised that there would be such a conflict at Northstar since Nabors 33E drilled all the wells. NOT testing the lower pipe rams may be acceptable for starting operations on this well provided the prior plugging operations are determined competent. I took forward to your reply.

The quick summary is sidetrack NS16a and finish NS34. N~33 will be deferred unti# the '09 ice road season. We're actively building ice to the island - we need sufficient ice road thickness to support Schlumberger's cementer, before we can start any openhole drilling. A# this time we're estimating about Jan 26m for heavy equipment travel on the ice road. We plan to MIRU on NS16 and begin the tubing 8~ 9-518" casing cut and pull on abou# Jan 18th. That will a#low us about a week of rigging up and dealing with the uncertainties associated with the decomplete -get #hat off the critical path. So our first BOP test will be sometime around Jan 22"d. In summary, we will cut/pull the 9-5/8" below the 13-318" surface casing shoe, pump cement, sidetrack from below the surface pipe w/ 12-1/4" to the Miluveach and cement 9-518" casing, drill the Miluveach/Kingaksnd line with 7" to the top of Sag, drill the Sag/Ivishak production hole and cement in a 4-1/2" liner, then complete with 4-1/2" 13Cr tubing. I've attached the approved NS16A PTD for your reference. NS16A sidetrack should take ~35 days. NS34, #o refresh your memory, was attempted last year but we lost the hole and BHA in the MiluveachlKingak sec#ion. The we## is suspended with 13-3/8" surface casing set in the SV sands, and 9-518" intermediate casing cemented into the top of Kuparuk. We pumped cement into the openhole below the 9-5/8" shoe. An extensive review of the log data suggests the Miluveach instability was probably driven by proximity to faulting and wellbore roof collapse associated with borehole inclination approaching that of bedding planes (Drit#ing is still trying to blame the Geologist for these, again). Our solution wilt be to move the well away from the fault as far as possible (limited by exiting the 9-518" shoe) and reduce the inclination of the hole thru the shales. We will not underream the Miluveach/Kingak, from 8-1 /2" to 9-112", as we've done in the past - underreamers make dealing with unstable hole conditions very difficult. instead of opening the hole we'll reduce the liner size from 7" to 6-518", down to top of Sag. We'll finish the production hole a 5-7/8" bit and 4-112" cemented liner. We have plenty of contingency cases lined up in the event wellbore instability continues to be a problem. Dave Johnson is currently working the PTD application and you guys should see it sometime next week. NS34A should take about 5 weeks to finish. 1've attached a couple of slides which summarize NS34.

The NS33 displayed very similar total gas to the N509 well. The NS08 well displayed total gas readings at least a magnitude greater (max 367 units vs. 5915 units) than either the NSOB or the NS33.

The formations exposed in the original hole are Kalubik shale, Kuparuk D shale and Kuparuk C sands (tight). The Kuparuk C is the only possible hydrocabon bearing zone exposed. The original hole TD'd at the base of the Kuparuk C sands and did not penetrate any Kuparuk A sands. 2. After penetrating the Kuparuk C in the original hole, our BGG increased from 134 to 329 with 10.3 ppg mud. We think it is too tight to be productive. 3.

It would seem that there isn't a need to have made the request. By successfully accomplishing your last primary cementing operation, isolation with the open hole intervals has been achieved and operations in the prior hole section completed. Your operation is not under any requirement to test the new NU on any time schedule related to the operations you have just completed. The initial BOP test for the new NU is in preparation for drilling the new hole section and there is much preparatory work to do prior to even tripping in the hole that will take multiple days. The rig supervisor's should contact the Inspectors with the usual notice, although given the requirements for travel to North Star notice earlier than that may be appropriate. If you or the others have any questions, please message or call.

As you know, we are in the process of of re-starting the production facility at Northstar and non-essential person are on the beach for a few hours. We should be back at work this evening, at which time, we will ND the 16-3/4" BOP and NU Nabors' 13-5/8" BOP. That may take a few days. We also need to prepare the rig for MOBM. We respectfully request that the initial test of the 13-5/8" BOP's take place when we have all of our miscellaneous surface work finished and we are ready to trip in the hole to drill out.

Date: September 18, 2007 NS33 is currently scheduled to be drilled by Nabors 33E with operations commencing on or about January 20, 2007, depending on ice-road access. NS33 is an ERD well which incorporates a 5-string well design. As such, an extra casing string will be set in the T/Colville: thus casing off the Ugnu, West Sak and Schrader Bluff before drilling ahead. The additional casing string divides the typical intermediate hole section into two distinct sections. As such, this approach improves the overall wellbore stability while drilling. Although the NS33 well plan passes Major Risk criteria, there is a close approach issue for this well as it passes NS32: a disposal well. In accordance with Northstar Policy covering close approach above the SSSV, NS32 is not required to be shut in. However, we plan to constantly monitor the OA and IA pressures while drilling and opening the ~ surface hole. The monitoring will be done by the mudloggers and/or facilities personnel. A Diverter waiver is hereby requested for NS33. To date, no development well drilled ~ through the Northstar upper stratigraphic intervals has experienced any difficulty with shallow gas. All surface holes have been drilled and cemented to a common depth of approximately 3,170' TVDss depth, 0150' TVD below the top of the SV6), with the exception of one well, which extends into the SV5 3280' TVDss. Well mud logs and seismic data do not indicate the presence of a shallow gas hazard. To accommodate the extra casing string, the surface casing in NS33 will be 16". We plan to install 16-3/4" BOPE on the 16" surface casing in accordance with 20 AAC 25. 035 (e)(2)(A). This BOP stack will be used while drilling to the T/Colville only. As such, t maximum anticipated surface pressure (full column of gas from TD to surface) is 18 psi. The 16-3/4" BOP stack will include: (1) annular preventer, (1) set of pipe rams and (1) set of blind rams in accordance with 20 AAC 25.035 (e)(1)(A). For the first intermediate string, we plan to set and cement 11-3/4" casing into the T/Colville at 16,161' MD / 6976' TVD. Prior to running the 11-3/4" casing, the pipe rams will be changed to 11-3/4" casing rams and the bonnet seals tested to ~-596'psi. ~ ~ G~.. 25o d In the remaining hole sections (below the 11-3/4" intermediate casing), the maximum anticipated surface pressure (full column of gas from TD to surface) is 3981 psi. For these remaining hole sections, we will be utilizing Nabors 33E 5000 psi four preventer stack (3 rams and an annular) in accordance with 20 ACC 25.35 (e)(2)(B). • • The subsequent operations require two (2) drilling liners: +/- 7500 ft 9-5/8" drilling liner, and +/- 2055 ft 7-5/8" drilling liner. For these operations, we are requesting a variance to 20 AAC 25.35 (e)(2)(B)(iv) that requires 2 ram preventers for the liner AND 2 ram preventers for the DP. We propose instead to use one (1) casing ram for the liners when run and a VBR to cover any size drill pipe used in the running string. This proposal would provide one ram and the annular preventer for the liner, as well as, one ram and the annular preventer for the DP. This scheme does not necessitate changing both pipe rams after picking up the liners. In the event of a well control incident, our standard practice is to immediately cross-over to DP to allow annular to ram stripping (if required). NS33 will utilize gas detection equipment the entire well. It is also planned to use mudlogging services below the surface casing to TD. In that the depth of this well precludes the use of slick line deployed BHP bombs, we hereby request a waiver to Field Rule 5 "Reservoir Pressure Management and iMonitoring': As such, we respectfully request that no BHP bomb be required. `Please find attached the NS33 Well Plan Summary, directional plan, and proposed completion diagram.

The targeted reserves are in the primary Northstar Ivishak structure. The target location (T/Sag) is located some 21,635' northwest of Northstar island. As such, NS33 will be the longest well (VS) drilled at Northstar and will be the longest well (VS) in Alaska. TMD will be 25,638'. VS at TMD will be 21,806'. The well will utilize 24" drive pipe which was installed in May, 2006. NS33 will have 16" surface casing installed with the shoe between the SV6 and the SV5 as is the norm. A string of 11-3/4" intermediate casing will be set and cemented through the Ugnu and Schrader Bluff sands with the shoe into the top of the Colville mudstones. Below the 11-3/4" intermediate casing a 10-5/8" hole will be drilled and under reamed to 12-1/4" with a RWD tool. It is planned to use MOBM to drill this hole section. A 9-5/8" drilling liner will be set and cemented in place with the shoe into the Miluveach. Next, an 8-1/2" hole will be drilled and under reamed to 9-1/2" with a RWD tool. MOBM will be used for this hole section as well. A 7-5/8" drilling liner will be set and cemented in place with the shoe into the top of the Sag River formation. Finally, the production zone will be drilled using a 6-3/4" bit to TD. Then a 4- 1/2" production liner will be set with blank pipe down to the T/Ivishak and slotted pipe below. The blank and slotted sections will be separated by an external "Swell" packer. Aliner-top / packer and PBR will be used for annular isolation. The well will be completed with 4-1/2" chrome tubing as is the norm. Pre-Riq Work: 1. Install the ABB Vetco 24" mudline hanger profile and 24" riser adapter.

The rule states that the surveys may be "stabilized static pressure measurements at bottom-hole or extrapolated from surface (single phase fluid conditions), pressure fall-off, pressure buildup, multi-rate tests, drill stem tests, and open-hole formation tests". I spoke with BP production engineer Robert Younger about this waiver request. NS-33 will be highly deviated (70 deg inclination by 3500' md) and will be the longest reach well drilled in Alaska. The reservoir datum of 11,100'ss is 10 ss' deeper than the planned TD of 25,638'md. Mr. Younger's slick-line model suggests that the maximum depth reachable will be about 23,000'md (+/- 9300' ss) assuming there are no dog-legs. Mr. Younger believes this to be optimistic, and he is concerned that changing fluid levels in the well could cause serious errors in estimating the BHP to datum. It is premature to grant a waiver of the requirement to obtain a BHP survey. However, the Commission will accept slick-line deployed BHP measurements taken as deep as possible in the well and extrapolated to datum based upon measured pressure gradient. The Commission will not require that asingle-phase gradient exist from the gauge depth to datum. If BP finds upon completion of the well and during the initial slickline run to retrieve the PX plug that the conditions make further slick-line runs too risky, the Commission may reconsider waiver of this BHP requirement at that time. • SONDRA D STEWMAN BP EXPLORATION AK INC "Mastercard Check" PO BOX 196612 MB 7-5 ANCHORAGE, AK 99519-6612 as-sii2sz 1'47 _ J L,, -.

Specifically for the NS33A well, determine a probable Oil/Water contact based on fluid pressure gradients. Comments: Run 6 was conducted with the StethoScope 475 tool between 16-Apr-2009 and 17-Apr-2009 in the 5.875" hole, from approximately 25,617 ft to 25,828 ft (Measured Depth). A total of 26 tests were attempted. Of those attempts, data was acquired for 24 tests. Of those 24 tests, 18 were completed with normal results, 3 were 'No Seal', 2 were 'Tight' and 1 was 'Dry'. Overall, the quality of the tests was good - see the comments on specific tests in the Test Point Table. The test quality is graded by color, with Green being the highest (see the table below for grading explanation). Eleven of the normal tests were acquired using the Time Optimized Pretest (TOP) 2-C sequence and the remainder were acquired using the 2-D sequence, as noted in the Test Point Table. The data used to generate this report was the Recorded Mode FPWD475 StethoScope data, processed using PD-Plot software (Vers 7.1.56).
