The objective is to convert this well from bas lift into a jet pumped well to increase its on-time by warming it up. Proposed Program: 1) Set catcher. Pull #1,3,4. Dmy #3, 4. Load IA. Dmy #1. MIT -IA to 3000 psi (max power fluid supply pressure = 2300 psi). 73m," ,, , - c-Lc_�4�w a. Optionally, could open the sliding sleeve and use it as a flow path while loading rather than station 1, then close it. 2) Brush sliding sleeve at WSL discretion. Open sliding sleeve. Pump —10 bbl of crude down IA to confirm sleeve is open. 3) Set jet pump insert with check valve (E+10) at 5769'. Pump 50 bbl's of crude down IA at 2 bpm to confirm we have a flow path. 50 bbl should be plenty to catch pressure and know we are going through the jet pump. BP Exploration (Alaska), Inc. P.O.

Cammis~ion Anchorape ~a~-- pc~~- ~, = aLD 4~ Enclosed please find multiple copies of a spreadsheet with a list of wells from GPB L- Pad that were treated with corrosion inhibitor in the surface casing by conductor annulus. 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.

The sampling program consisted of running two 1-gallon sample chamber and one multi-sample modules, which was comprised of six MPSR sample bottles. The primary objective of this logging run was to capture several high-quality pressurized hydrocarbon samples for PVT analysis. The first sampling point consisted of filling one 1-gallon MRSC (292) at 5,956 ft MD in the OA sand. One MPSR (1402) was filled at the second sample point of 6,324 ft MD in the OBc sand. One MPSR (1399) was captured in the Upper OBa sand at 6,089 ft MD. The fourth sampling point in the OBb sand at 6,196 ft MD was comprised of two MPSRs (1400 & 1397). One 1-gallon MRSC (226) was filled at the fifth sampling depth of 6,124 ft MD in the Lower OBa sand. The sixth and final sampling point of 6,586 ft MD consisted of filling two MPSRs (1401 & 1398) in the OBd sand. An attempt was made to capture a sample in the Mb2 sand but was unsuccessful. Upon retrieval to surface, the sample chambers were transported back to the Schlumberger base in Prudhoe Bay, AK. An opening pressures was obtained on the 1-gallon sample chamber (MRSC 292) prior to heating and agitating the samples for ten hours. Upon completion of restoring the 1-gallon sample chamber, the sample was transferred into two Conventional Sample Bottles (CSB). The remaining fluid in MRSC 292 was blown down into a 1 gallon IATA steel can. Opening pressures were obtained on the six MPSRs prior to bleeding down each sample into atmospheric containers. An opening pressure was also obtaining on the 1- gallon sample chamber (MRSC 226) prior to bleeding the contents into an atmospheric container for shipping. Both pressurized hydrocarbon samples have been sent on to the Oilphase-DBR PVT lab in Houston, TX for analysis. The atmospheric oil samples collected have been sent on the Baseline Lab in Shenandoah, TX.

O 1, T 11 N, R 11 E, UM Dear Mr. Tirpack: Enclosed is the approved application for permit to drill the above referenced development well. 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).

The Schrader in the target fault block is expected to be normal pressured at 8.3-8.6 ppg EMW. This pressure is estimated based on offset well pressures and material balance. Hydrates and Shallow gas A. Gas Hydrates are expected at L-pad from the SV5 thru the SV1 sands below the base of the permafrost. Setting casing through the SV1 should keep hydrate exposure from extending past the surface hole. Recommended practices and precautions for drilling hydrates should be followed in the surface hole. Occasionally hydrates are encountered below the SV1. III. Lost Circulation/Breathing A. Lost circulation is not expected at fault #1. This fault has been penetrated by most wells drilled from L Pad. B. Breathing is not expected on this well. IV.

L-Pad development wells may have "kick tolerances" in the 25 bbl range. A heightened awareness of kick detection, pre-job planning and trip tank calibration will be essential while drilling/tripping the intermediate/ roduction intervals. V. Hydrogen Sulfide L Pad is no _designated as an H2S site, however Standard Operating Procedures for H2S precautions should be followed at all times. No measurable H2S is being produced from the formation at this time. However 5 - 50 ppm is expected as a result of the use of Ivishak gas lift gas. All LV Pad gas lift wells will likely have H2S in this concentration. Note that all injection has been with produced water not seawater. H2S levels are expected to remain low until the waterflood matures. Recent H2S data from the pad is as follows: Adjacent producers at Surface: Adjacent producers at TD: L-106 50 ppm L-201 10 ppm L-102 20 ppm VI. Faults A. Two faults are expected to be crossed in L-204. No losses are expected to be associated with these faults. No faults are expected in the reservoir section, although sub seismic faults with throws <25' may be encountered.

Re uest The AOGCC is in the process of developing a guideline document clarifing the intent of the regulations pertaining to function pressure testing ram type BOP's. BPXA requests a variance to the provisions of 20 AAC 25A35 (e)(10)C regarding the function pressure test requirement after tike use of BOP ram type equipment far other than well control or equivalent purposes, except when the routine use of BOP ram type equipment may have compromised their effectiveness. (Example would be when pipe rams are inadvertently closed on a tool joint during routine operations.} The activities associated with this request will not compromise the integrity of the BOP equipment. Background AOGCC regulations require rams that have been used in the course of primary drilling & completion, workover and through tubing drilling operations be function pressure tested before the next wellbore entry. This is not a new regulation. The intent of this regulation is to ensure that ram type equipment has integrity after it has been utilized in a wellbore...for example; to ensure integrity if a ram was closed on a tool joint. The exact regulation language is: "if BOP sealing ram type equipment has been used, it must be function pressure-tested, before the next wellbore entry, to the required working pressure specified in the approved Permit to Drill, using anon-compressible fluid, except that an annular type preventer need not be tested to more than 50 percent of its rated working pressure;" The pertinent sections are: 20 AAC 25.035 (e)(10)C PRIMARY DRILLING AND COMPLETION; 20 AAC 25.036 (d}(4) THROUGH TUBING DRILLING AND COMPLETION; 20 AAC 25.285 {f}(2) TUBING WORKOVERS: 20 AAC 25.286(e)(1) WORKSTRING SERVICE OPERATIONS This issue has been discussed with Winton Aubert at the AOGCC. The test requirement in the regulation is intended to apply to ram type eauipment only. The AOGCC understands that ram type BOP's are utilized for purposes other than well control in the normal coarse of operations. The regulations allowing a variance are at 20 AAC 25.035(h} PRIMARY DRILLING AND COMPLETIONV; 20 AAC 25.036(f} THROUGH TUBING DRILLING AND COMPLETION; 20 AAC 25.285(h} TUBING WORKOVERS; 20 AAC 25.286(g} WORKSTRING SERVICE OPERATIONS...which says generally: 20 AAC 25.035(h)...
