Drilling&Wells ConocoPhillips Well Intervention Alaska 1E-08 Acid Treatment (10404365) Engineer: Jason Burke Wells Engineer 907-231-4568 DAD, dynamic acid dispersion, is an acid outside-phase emulsion prepared and stabilized with dispersing agent F103. The purpose of the dispersion is to simultaneously dissolve acid-soluble minerals and remove oil paraffinic deposits. Target areas can be tubulars, perforations or the critical matrix. Objectives: Spot Dynamic Acid Dispersion (DAD) treatment with CT into perforations to increase injectivity • Coiled Tubing: Spot 100 bbl of DAD into formation 1. MIRU CT, MU 5 port wash nozzle BHA 2. Begin RIH, enter slotted liner completion at 7262' MD. 3. Continue RIH until end of first liner section at 8325' MD is reached or until CT locks up 4. When CT has reached ultimate depth begin pumping DAD treatment. When treatment is exiting the CT (depending on CT volume) shut in the choke and begin POOH at a rate that will allow treatment to be spotted from final depth to 7262' MD (At 8325' MD 100 bbl/1 BPM=100 min & 1063 ft / 100 min=10.5 fpm). Chase the DAD treatment out of the CT with produced water or diesel. a. Do not exceed 4500 psi surface pressure 5. After an additional 5 bbl of fluid has been injected behind the treatment POOH 6. RDMO CT. Return well to injection.

A 407 was filed 2/4/11 documenting the work accomplished with Doyon 141 to set up the well for a coil drilling work. 2. The status was listed as "oil" however this was changed to "suspended"which is correct since additional work was needed before the well would be capable of producing or injecting. 3. WL/WL work was begun 2/9/11 with CT operations following to drill the 6 laterals/spokes in March and April 2011. The CT work was completed about April 20 and the 407s for those penetrations were filed with the status of 1-oil. 3. A 404 was filed by the Production Engineer Specialist on May 4 changing the well status of 1 E-08A from suspended to 1-oil. 4. Our production record shows the well complex produced 28 days in May and 25 days in June. It further shows the well complex has injected water for 12 days in July. August information has not yet been posted. Regulations require that an operator obtain approval from the Commission to convert a well from development to service prior to initiating injection. The Commission has no record of any Form 403 being filed to convert any of the penetrations to service. Any injection that has occurred is not authorized. Commissioner Foerster has been apprised of this matter and she has directed that the following be communicated to you: Pending resolution of this matter, CPAI is directed to cease injection into 1E-08A and secure the well appropriately. At your earliest convenience, prior to September 23, you should contact me or Guy Schwartz to arrange a meeting to discuss this matter. The Commission reserves the right to pursue an enforcement action in this matter. Please keep Guy and me apprised of CPAI's work accomplished to comply with the Commissioner's directive. Tom Maunder, PE AOGCC From: NSK Problem Well Supv [mailto:n1617@conocophillips.com] Sent: Saturday, September 17, 2011 12:44 PM To: Maunder, Thomas E (DOA) Subject: 1E-08A (PTD 210-181) Request to WAG to MI in prep for AA submission 09-17-11 Tom, ConocoPhillips requests permission to WAG 1E-08A (PTD 210-181)to MI in order to run diagnostics before applying for an AA. This well has a high packer and we need to confirm that no out-of-zone injection takes place while on gas. Instead of first applying for a water-only AA and then needing to amend after we get gas tests, I thought it would be expedient to conduct the MI tests first before requesting an AA. A passing, witnessed MITIA was performed on 8-30- 11. I'm not sure if you were sent the CBL data, so I've attached another copy to help base your decision. We still plan to run the same diagnostic program as was done on 1A-04A: 1. getting a baseline RST while on water, 2. putting the well on MI and getting an IPROF, 3. wagging back to water and getting a follow-up RST to look for residual gas.

This work will be done with the coiled tubing drilling (CTD) rig, Nabors CDR2-AC. Operations scheduled to begin March 1, 2011. • The objective of the CTD project is to drill five lateral sidetracks (1E-08AL1, 1E-08AL1-01, 1E-08AL1-02, 1E- 08AL2, and 1 E-08AL2-01)targeting the A4 and A5 sands. (NOTE: In some previous documentation four lateral sidetracks were referenced as the plan. Upon more detailed directional planning, five laterals will be necessary to reach the objectives of the project.) The ultimate, intended service for these laterals is MWAG injection. The permits have been submitted as producers, as requested by the State, due to the fact that the laterals are planned to be pre-produced for a period of time beyond 30 days. Two, single-string casing exits will milled through the 5.5" liner in the parent wellbore. Three sidetracks are planned from one window and two sidetracks from the second window. Some pre-rig wellwork is necessary to prepare the wellbore for the arrival of Nabors CDR2-AC. A Sundry application to cover this work was submitted to the State on February 3, 2011. Attached is an outline of the pre-CTD wellwork planned for 1E-08A and a brief summary of CTD work. If you have any questions or require additional information please contact me at my office 907-263-4093 or on my cell phone 907-230-7550. Attached to this application are the following documents: — 5 Permit to Drill Application Forms: 1E-08AL1, 1E-08AL1-01, 1E-08AL1-02, 1E-08AL2, 1E-08AL2-01 — Summary of Planned Operations — Proposed Schematic — Directional Plans — Anti-collision Review — BOP Schematic If you have any questions or require additional information please contact me at 907-263-4093 (office) or 907- 230-7550(cell).

In 1984 a workover was performed to install a selective completion allowing for isolation between the A and C-sands. Blast rings were placed in the straddle section. The wellbore was eventually converted to water injection in 1990. A leak was detected in the straddled section of tubing in 1995. A tubing patch was used to repair the leak and from that point on the well functioned as an A-sand only injector. From 2000-2008 the well was shut-in due to a corroded well line. When placed back in service in 2008, additional leaks were found in the straddle section. Leaks to the C-sand continued to be a problem in the wellbore. Since this well had been identified as a candidate for CTD, A-sand only sidetracks, the well was shut-in in February 2010 to allow for depressurization of the A-sand by crossflowing into the C. Preparation for CTD work began in November 2010 with a rig workover. The purpose of the workover was to replace the 3.5" leaking selective completion with new 3.5" tubing. During recovery operations, the tubing in the selective section parted resulting in some blast rings falling downhole. Due to the complications and low likelihood of recovering any equipment with broken blast rings present, workover operations were abandoned. A cement retainer was set and cement pumped. A rotary sidetrack was immediately planned in order to replace the well and set it up for CTD. The rotary sidetrack began January 5, 2011. After successfully sidetracking out of 1 E-08 and reaching TD, a 5.5" liner was run to bottom. While confirming circulation with the liner in place, the hole became packed off. In an attempt to establish circulation and place cement above the Kuparuk, perforations were shot in the liner and a cement retainer was used for circulating in cement. Additional problems ensued but ultimately after a bond log was run, all parties agreed there was adequate cement above the top of the Kuparuk to proceed with running the tubing completion. This cement work will help provide additional isolation between the A and C sands. The final 3.5" completion required three packers set in the liner to isolate the upper set of cement perforations as well as a liner leak. Operations on the rotary sidetrack were completed on January 31, 2011. CTD rig, Nabors CDR2-AC, is planned to begin operations on 1 E-08A on March 2, 2011. After completion of the CTD work, the well will be pre-produced for approximately 3-6 months. After the pre-production period, the well will return to its intended service, MWAG injection. Operational Outline Pre-Rig Work 1. Changeout all gas lift valves to dummy valves. Drift wellbore with dummy whipstock. 2. Perforate the 5.5" liner across from potential CTD kickoff locations. Planned kickoff points are —7645' MD and —7564' MD. Perforations will also be shot across a backup kickoff location at—7527' MD. 3. Set the lower whipstock at—7645' MD. 4. Cement squeeze the openhole section behind the 5.5" liner. Contaminate and cleanout cement to the top of the whipstock at—7645' MD. (NOTE: This cement will provide additional isolation between the A and C sands as well as ensure there is good cement behind pipe at the kickoff locations.) 5. Drift and tag the top of the whipstock. 6. Run a cement bond log to evaluate the cement quality. 7. Set BPV and prepare wellsite for rig arrival.

Cutting through these sections at high inclinations and ensuring no motor transitions occur within a close proximity should help mitigate the problem. - The 1 E-08AL1 lateral is very long, -4000'. Weight transfer towards the end of the lateral is a concern and so the lateral has been planned with minimal doglegs utilizing rib-steer motor(RSM) technology. - Drillsite 1E is an H2S pad. The maximum recorded H2S reading on the pad in 2010 was 130 ppm at well 1E-02 (09/15/2010). Well 1E-121 is the closest producing well to 1E-08 (located -30' to the right on surface) and had an H2S reading of 30 ppm on (09/15/2010). All H2S monitoring equipment should be operational. Fluids Program - Chloride-based Biozan brine (8.6 ppg)will be used for window milling operations. - Chloride-based Flo-Pro mud (9.8 ppg) for drilling operations. - 1E-08A does not contain a subsurface safety valve so completion kill weight fluid will be used for running completions. Disposal - No annular injection on this well. - Class II liquids to KRU 1R Pad Class II disposal well - Class II drill solids to Grind & Inject at PBU Drill site 4 - Class I wastes will go to Pad 3 for disposal.

Reservoir Pressure The most recent static BHP survey in well 1E-08 was taken October 21, 2010. The reservoir pressure was measured at 2760 psi at 7274' MD/6286' TVDss, corresponding to 8.4 ppg EMW. Well Control - Two well bore volumes (-215 bbl) of 12.0 ppg kill weight fluid will be within a short drive to the rig during drilling operations. In this situation, a"wellbore volume" is defined as the tubing volume plus the volume of the longest lateral. - BOP diagram is attached for operations with 2" coil tubing. - Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3500 psi. Maximum surface pressure anticipated while sidetracking out of 1 E-08 is -2365 psi, assuming a gas gradient to surface. This maximum potential surface pressure is calculated using the maximum expected reservoir pressure of 3000 psi based on recent pressures within the area and assuming a gas gradient of 0.1 psi/ft. - The annular preventer will be tested to 250 psi and 2500 psi. Managed Pressure Drilling Managed pressure drilling (MPD) techniques will be employed to provide constant bottomhole pressure by using 9.6 ppg drilling fluid in combination with annular friction losses and applied surface pressure. Constant BHP will be utilized to reduce pressure fluctuations to help with hole stability. Applying annular friction and choke pressure also allows use of less expensive drilling fluid and minimizes fluid losses and/or fracturing at the end of the long well bores. A hydraulic choke for regulating surface pressure is installed between the BOPE choke manifold and the mud pits, and is independent of the BOPE choke. Using this technique will require deployment of the BHA under trapped wellhead pressure. Pressure deployment of the 2%" BHA will be accomplished utilizing the 2%" pipe rams and slip rams. The annular preventer will act as a secondary containment during deployment and not as a stripper. The well will be loaded with overbalanced fluid prior to running completions. Operating parameters and fluid densities will be adjusted based on real-time bottom hole pressure measurements while drilling and shale behavior.

Many difficulties were encountered in getting the 5 1/2 liner cemented ... the initial primary job packed off before any cement was pumped and the remedial shoot and sqz cementing went poorly also. There is enough cement above the Kuparuk zone to assure injection control but later during the completion phase a leak was also found in the liner at 6293' and so an additional packer was run above that to isolate it. This puts the top packer 1350' away from the injection zone (see attached 1E-08A well schematic) .... Well past the normal 200' limit for injectors. Additional sqz perfs have been shot below the lower packer and cement placed(for A to C sand isolation) ... the current operation is under-reaming the cement and then acquire another CBL in the 5.5"liner section below the packers. The well will initially be pre-produced for 3-6 months with it used ultimately as an injector( CPAI may request MWAG service). With the marginal cement quality and the placement of the upper packer an Administrative Approval (AA) should be generated for this well to insure extra safeguards and monitoring are in place before injection is started.
