Joe Lastufka, 564 - 4091 Well Number Permit No. / Approval No. Drilling Engineer: Matt Ross, 564 - 5782 INSTRUCTIONS General: This form is designed for submitting a complete and correct well completion report and log on all types of lands and leases in Alaska. Submit a well schematic diagram with each 10 -407 well completion report and 10 -404 well sundry report when the downhole well design is changed. Item 1 a: 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 and Ground Level elevation in feet above mean sea level. 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: Report true vertical thickness of permafrost in Box 20. Provide MD and TVD for the top and base of permafrost in Box 28. Item 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool. Item 24: 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). Item 27: Method of Operation: Flowing, Gas Lift, Rod Pump, Hydraulic Pump, Submersible, Water Injection, Gas Injection, Shut -In, or Other (explain). Item 28: Provide a listing of intervals cored and the corresponding formations, and a brief description in this box. Submit detailed description and analytical laboratory information required by 20 AAC 25.071. Item 30: Provide a listing of intervals tested and the corresponding formation, and a brief summary in this box. Submit detailed test and analytical laboratory information required by 20 AAC 25.071.

History of B -20. Well B -20 was a rotary well drilled in November 1982 as a Zn2B well. A cement bond log run March 1986 indicated no cement from the Sag to Z3 and poor cement from Z3 to TD. To shut -off gas, in the course of 11 years, 4 cement squeeze jobs were unsuccessfully performed. After 2 failed patch attempts, a RWO was completed in October 2008 which restored integrity with new tubing. The most recent calliper from 12/20/11 showed the tubing to be in good condition with no b' significant wall penetrations. All sidetrack screening pressure tests passed. Reason for sidetrack. B -20 is no longer a competitive well due to low productivity and has no remaining wellwork options. The proposed sidetrack will access a target in the Zn2A. Proposed plan for B -20A is to sidetrack with the SLB /Nordic 2 Coiled Tubing Drilling rig on or around April 25 2012. The existing perforations will be isolated by the primary cement job for the liner. The sidetrack, B -20A, will exit the existing 7" liner and kick off in Zn2C and land in Zn2A. This sidetrack will be completed with a 3 -1/4" x 2 -7/8" liner in the production interval. The following describes the work planned and is submitted as an attachment to Form 10 -403. A schematic diagram of the proposed sidetrack is attached for reference. v2 /l p(o`lvcy 01/ q 6 J 1 i 4'5gaa f Cohcv : // an of 54104,/ �/I o of ve," f L/� 19 -�� rw let 1v / ire Cv,ip / k-9 // k' 5 4'�iO7 ' 7 /P?" f c yC/er 1 41 forT o1 - pie /1)0/ S /O ,�A' /t recd Td yy • • Pre -Rig Work: (scheduled to begin April 2 2012) 1.

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. If you require any additional information, please contact me or my alternate, Anna Dube, at 659-5102. Sincerely, Torin Roschinger BPXA, Well Integrity Coordinator BP Exploration (Alaska) Inc.

There was no danger of losing well control, but we felt that it was to our advantage to take the gas-cut circulation fluid through our manifold and gas buster. We contacted AOGGC, North Slope Inspectors, within minutes of the well shut-in, leaving a message. September 27th, at about 0630-hours, we gave AOGCC NS Inspectors atwo-hour notification that we were going to test the Hydril. Bob Noble returned the call shortly thereafter waiving the State of Alaska's right to witness the Hydril test. It was successfully tested at 1130-hours, September 27th, to 250-psi low and 3,500-psi high without any adjustment or repairs to our BOP equipment.

There is no report of the patch installation. Could you please send the installation reports? Email is fine. According to the "matrix", a 404 should be sent when a patch is installed.

I. Supervisor ~\/\c~- E~\ SUBJECT: Petroleum Inspector January 18, 2001 Safety Valve Tests PrudhOe Bay Unit B Pad Thursday, January, 18, 2001: I traveled to BPXs B Pad and witnessed the 'semi annual safety valve system testing. As the attached AOGCC Safety Valve System Test Report shoWs I witnessed the testing of 17 wells and 34 components with 2 failures. The. Pilot on well B-18 tripped below the required set point and the pilot on well B-21 was frozen. Both failures were repaired and-suCessfully retested before I departed location. The' new style pilot insulation box fabricated using pipeline insulation installed on most wells on this pad should be installed onthe remaining SVS pilots to eliminate the freeze up problems evident on this pad. I also inspected the well houses on this pad while witnessing SVS testing. All the well houses inspected were clean and the equipment appeared to be in good cOndition.

RIH with slickline and run a drift to ensure no obstruction exists in wellbore and to tag PBTD. Do not perform acid'job unless 50' of rathole exists. 2. Obtain wellhead sample. Test for emulsion tendencies using. API RP 42 testing procedure with spent and unspent acid. Acid system to contain 5000 ppm ferric iron. Adjust additives as required. 3. Obtain rate test at the same choke setting that will be used for the post rate test. 4. Pull SSSV and isolate SSS. · 5. MIRU CTU and stimulation company. Lay lines and pressure test to 4000 psi. 6. Sample acids to insure acceptable concentration and that iron count is less than 350 ppm. 7. RIH with Lynes 130 rib inflatable packer and tie into tubing tail for depth control. The 130 rib tool has less chance of failure if set in perfs. As target interval is only 10 ft. some perfs may be covered when packer is set. Preference is to err towards the high side instead of covering perfs in the lowest interval. 8o Set packer in the 10 ft blank interval between 9790 and 9800'. Pressure annulus to 500 psi and hold at this level during job. However, if behind the pipe communication is observed on the backside, began pumping down the annulus at 1/2 BPM. As no open perfs exist on the backside objective is to hold pressure without breaking squeeze down. If perfs do fail from the acid, pumping down the backside will at that time minimize perf exposure to acid. Do not bullhead wellbore fluids into interval being acidized. 9o Acidize 23' (92 holes) of Zone 2 perfs with 15% HCL acid. Maximum pressure is 4000 psi. Filter fluids to 3 microns. Pump as follows: A) 1500g 15% HC1 with 1.0 ppp OSR. B) 500g arctic diesel with 10% mutual solvent. C) Unseat packer and reciprocate across perfs. D) 500g arctic diesel with 10% mutual solvent. E) Displace to perfs with sea or produced water. 10. POOH while pumping diesel. 11. Return well to production ASAP. 12. Obtain rate test at same choke size as pretreatment setting.

The proposed post workover perforation strategy is perforate 9800'-9818', 9820~'-9822' and 9825'-9838' MD BKB and to stage reperforate intervals 9747'-9757' at limited shot density. 1. Rig up coiled tubing unit and pressure test BOP's to 4000 psi. 2- Perform mud acid perforation wash and sump cleanout. 3. Fluid pack the wellbore with produced water. 4. Pump cement with surfactant/mutual solvent pre-flush. 5. Perform cement squeeze on existing perforations. 6. Contaminate cement in wellbore. WOC. 7. Reverse out contaminated cement and test squeeze. 8. Perforate the following intervals at 4 spf: 9800' - 9818' MD BKB (18') 9820' - 9822' MD BKB (2') 9825' - 9838' MD BKB (13') 9.
