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. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10 -404, Report of Sundry Operations.

Assessment of the 7" drilling liner isolation is as follows: • While running the 7" drilling liner losses were experienced uphole. Once circulating at TD these losses had healed and full returns were seen at surface. • Possible indications of an improper cement job were remediated before operations resumed. An unsatisfactory test on the 7" indicated that pressure was leaking past the liner top packer. After running an isolation packer to isolate the leak, the integrity of the 7" x 9-5/8" overlap and 7" drilling liner was confirmed competent before proceeding ahead. • Once drilled out of the 7" shoe a FIT to 11.5ppg was performed with no irregularities indicating an inadequate cement job.

My questions were answered; however 1 have some further questions regarding the USIT log and the cementing operation. The USIT shows a very pessimistic presentation and I request an assessment of the 7" drilling liner isolation. Some difficulties were encountered running the liner, although they appear not to have affected the actual cementing which appears to have gone well. Was the pipe reciprocated? Afterwards, there were repeated attempts to satisfactorily test the 7" liner which may have affected the ultimate bond presentation. The 4-1/2" liner operation appears to have gone well. Thanks in advance.

The DIMS report has the wiper dart drop and the pump cement lines incorrect in order of action. I have attached the Schlumberger cementers tabular report and job plot confirming that cement was pumped before the wiper dart was dropped. 2.) U-05 tubing completion did not have gas lift mandrels (injector well). As such, no differential was needed to keep a shear disk in place. The rated collapse for 4-1/2" 12.6# L-80 tubing is 7500 psi so the 4000 psi pressure test of the IA was below 80% of tubing collapse (6000 psi). 1 have also attached a zip file with the USIT log dated 08/17/2009. I had to zip the file since it would have been too big to send uncompressed. Let me know if you need anything additional. Office number is 564-4373.

When the IA is pressure tested to 4000 psi after setting the packer and pressure testing the tubing, no internal pressure is reported held on the tubing. This is not how the operations is normally conducted as I remember. For production wells, the need to hold a differential is to maintain the shear out valve which is not included in an injection string. Could you provide a comment here?

This revision was necessary due a change in the bottomhole location greater than 500' laterally and 2009 as well revising the type of well to be drilled. This approval supersedes the original approval dated July 14, 2009. This permit to drill does not exempt you from obtaining additional permits or an approval required by law from other governmental agencies and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. When providing notice for a representative of the Commission to witness any required test, contact the Commission's petroleum field inspector at (907) 659-3607 (pager). Sincerely, Daniel T.

A 7" drilling liner with premium threads has been run to the top of the Sag River and partially cemented 1,000'. The production hole has been drilled with a 6-1/8" BHA to 12,112' MD. Geologic data indicates repositioning the lateral will better support the existing producer in the area. The proposed TD is in excess of 500' from the permitted TD.

A NW-SE trending fault (Fault A) is located east of the proposed TD of this well. This fault lies under the intermediate sail section of the well. Fault A vertically tips out at a depth of approximately 8300 ' tvdss and will not impact the well (The directional plan is 2300' above the shallowest occurrence of Fault A). Additionally, there is a N-S trending fault (Fault B) that lies 2350' west of the well TD. Well Control Well control equipment consisting of 5,000 psi working pressure pipe rams (2), blind/shear rams, and annular preventer will be installed and are capable of handling the maximum potential surface pressures. Based upon calculations below, BOP equipment will be tested to 4,000 psi. BOP regular test frequency for U-05A will be 14 days during drilling phase and 7 days during decompletion and surface casing work. BOPE and drilling fluid system schematics on file with the AOGCC.

The Ivishak in this fault block is expected to be under-pressured at 6.2 ppg EMW. This pressure is estimated based on offset well pressures. 4000 psi test pressure is in accordance with the RP for Prudhoe production well casing tests for injector wells. Lost Circulation/Breathing A. The U-05A RST will not cross any mapped faults. A NW-SE trending fault (Fault A) is located east of the proposed TD of this well. This fault lies under the intermediate sail section of the well. Fault A vertically tips out at a depth of approximately 8300' TVDSS and will not impact the well (The directional plan is 2300' above the shallowest occurrence of Fault A). Additionally, there is an N-S trending fault (Fault B) that lies 2350' west of the well TD. B. Lost circulation events in the area have been a problem. Severe lost circulation events have happened in production hole sections and have been fault related. U-02A production hole being the largest volume lost at 16,212 bbls. III. Kick Tolerance/Integrity Testing A. With the planned mud weights, the kick tolerance for the intermediate section is 186 bbls, and for the production section is infinite. The FIT/LOT will prove up adequate formation strength for expected EC D's. B. Integrity Testing Test Point Test De th Test a EMW Ib/ al 9 5/8" window 20-ft minimum from the 9 5/e" window FIT/LOT 11.2 minimum 7" shoe 20-ft minimum from the 7" shoe FIT/LOT 9.5 minimum IV. Stuck Pipe A. There are differential sticking tendencies across the Kingak in the intermediate section and within the under-pressured production section. Keep the pipe moving and follow Stuck Pipe Prevention Procedures while drilling and running the 7" casing in this interval of the well. VI. Hydrogen Sulfide A. U-PAD should be considered an H2S site. U-05 H2S data is not available. H2S levels above the 100 ppm threshold have been recorded on this pad. U-06B the closest well BHL location is 20 ppm as of 5/16/08. VII. Faults A. The U-05A wellpath is not expected to intersect any mapped faults. See Section II on lost circulation for more details. VIII. Anti-Collision Issues A.

Robert B; Hobbs, Greg S (ANC) Subject: U-05A (209-070) -Revised Cementing Practices Tom, To reply to your comment: Page 1 of 2 BP commissioned a study earlier this year to re-examine "Cre#aceous" or Ugnu intermediate and long string casing leak causes. Past studies have concluded tha# the casing leaks were related to cement placement above the Ugnu. The current study found that cement placement across the Ugnu was not consistently high enough or of sufficient quality to avoid the corrosion effects of connate or injected fluids. In addition, bringing the top of cement high enough to full cover the Ugnu adds considerable risk to the well. Cement can be introduced into the outer annulus, thus leading to inability to freeze protect the well. By injecting down the outer annulus to clear out any cement, the wel! runs a high probability of breaking the Ugnu formation at an unknown depth. For these reasons, Alaska Drilling and Wells has decided not to fully cover the Ugnu formation with cement. Instead cement will be brought to 1000 feet above the intermediate shoe for most wells designed to penetrate the Ivishak. TC II thread connections will be used in place of BTC connections to provide a gas tight, premium connection over the entire intermediate long string or liner.

As far as changing the cementing program, there have been other wells that have also had similar changes. I'd appreciate some further information on the engineering reason for the change. As discussed, there likely aren't Cretaceous issues at U pad. External corrosion issues are more known in the EOA area. I look forward to your reply.

The sidetrack plan for the U-05A (an Ivishak injector) includes the following during pre-rig operations: laying cement across the perforations, the 5-1/2" tubing will be cut 200' below planned whipstock exit point. The whipstock exit from the 9-5/8" casing is estimated at 4600' MD and will be milled using an 8-1/2" milling assembly. The 8-1/2" hole will be drilled to the Top of the Sag River where a 7" drilling liner will be run and fully cemented up to 150' inside the 9-5/8". A 6-1/8" pilot hole will then be drilled and plugged back. Kicking off of the cement plug, the production hole will be drilled with a 6-1/8" BHA building to horizontal and running through the Ivishak formation to TD. The liner will be a 4-1/2" L-80 and the tubing will be 4-1/2" L-80, tied into the top of the production liner.

The Ivishak in this fault block is expected to be under-pressured at 6.2 ppg EMW. This pressure is estimated based on offset well pressures. 4000 psi test pressure is in accordance with the RP for Prudhoe production well casing tests for injector wells. II. Lost Circulation/Breathing A. The U-05A RST will not cross any mapped faults. A NW-SE trending fault (Fault A) is located east of the proposed TD of this well. This fault lies under the intermediate sail section of the well. Fault A vertically tips out at a depth of approximately 8300' TVDSS and will not impact the well (The directional plan is 2300' above the shallowest occurrence of Fault A). Additionally, there is an N-S trending fault (Fault B) that lies 2350' west of the well TD. B. Lost circulation events in the area have been a problem. Severe lost circulation events have happened in production hole sections and have been fault related. U-02A production hole being the largest volume lost at 16,212 bbls. III. Kick Tolerance/Integrity Testing A. With the planned mud weights, the kick tolerance for the intermediate section is 186 bbls, and for the production section is infinite. The FIT/LOT will prove up adequate formation strength for expected ECD's. B.

Stuck Pipe A. There are differential sticking tendencies across the Kingak in the intermediate section and within the under-pressured production section. Keep the pipe moving and follow Stuck Pipe Prevention Procedures while drilling and running the 7" casing in this interval of the well. VI. Hydrogen Sulfide A. U-PAD should be considered an H2S site. U-05 H2S data is not available. H2S levels above the 100 ppm threshold have been recorded on this pad. U-06B the closest well BHL location is 20 ppm as of 5/16/08. VII. Faults A. The U-05A wellpath is not expected to intersect any mapped faults. See Section II on lost circulation for more details. VIII. Anti-Collision Issues A.

Sehlumberger PBU U-05APB1/A (P3b) Nabors 7ES Close Approach Analysis We have examined the potential intersections of subject well with all other potentially conflicting wells, according to the BPA Directional Survey handbook (BPA-D-004) dated 09/99. Method of analysis: 1. A list of wells to be analyzed is created in Compass by performing a global scan with an initial search radius of two hundred feet with an increment of one hundred feet for every one thousand feet of measured depth in the subject well. 2. Wells are analyzed using the Compass Anti-collision module (BP Company setup) with major risk safety factors applied. For problem wells that are plugged and abandoned or that can be shut in, risk-based safety factor may be used, with client notification. 3. All depths are relative to the planned well profile.
