On 6/10/2018 a remedial conductor top job was preformed to mitigate the surface casing leak, and on 6/13/18 the well passed an OA integrity test to 1,176psi. Per sundry 318-164 the well is now approved to be placed on injection to evaluate the success of the repair. At this time the well is reclassified as Under Evaluation and is on the 28 day clock for monitoring. An AOGCC witnessed MIT -IA will be performed once the well is on stable injection. Please mind fluid packed annuli when bringing the well on.

The flowback portion for this well became complicated. Due to the nature of the anticipated fluids to be flowed back and wellstock available to assist with the flowback, the original piping plan that would be used to assist the flowback changed. The updated piping configuration would require more than 700' of hard line rig up. Due to the increased risk associated with substantial footage of hardline install and operation, along with increased costs, the flow back portion of this job has been cancelled for now. The wellwork portion of this job was beneficial and the well will remain in its current completion configuration. We do anticipate the conversion to happen at some point in the future, when flowback risks can be better understood and mitigated.

In August 2012, bubbling was noticed in the conductor by surface casing annulus during a pressure test on the Outer Annulus indicating a surface casing leak. The well status was then changed to Not Operable. The well was secured with a downhole plug in the tubing, and the subsequent pressure test on the tubing passed. Current Status The well is classified as Not Operable because of bubbling noticed in the Conductor x Surface Casing annulus during pressure testing. Objective This procedure is to clean out the Conductor x Surface Casing annulus, then top off the annulus - with a cement or polymer blend to re-establish Outer Annulus integrity. Procedural steps Well Diagnostics/Special projects 1. Steam clean the Conductor x Surface Casing Annulus to top of good cement. 2. Perform top job on the Conductor x Surface casing annulus until clean returns are observed at surface. 3. Wait for top job to cure. Well Diagnostics/Well Integrity Superintendent 4. Perform pressure test on the Outer Annulus. Slickline 5. Pull tubing plug. Well Diagnostics/Well Integrity Superintendent 6. Change well status to Under-Evaluation. 7. Place well on injection and monitor conductor/cellar for any leaks. 8. Perform standard AOGCC witnessed pressure test on the Inner Annulus. Change well status to Operable if test passes.

You indicated that the well pressures were monitored through 75 minutes and IA only gained an additional 2 psi for a total gain of 6 psi during final 30 minutes of the MIT. Increasing IA was attributed to fluctuating injection temps during the test. The well exhibits sufficient stabilization for calling this a passing test. When you submit the test report at the end of the month, please include the 75min pressure data in the remarks of the form, along with a brief note about the fluctuating injection temps.

Mr. Bob Noble was the AOGCC witness on location and deemed the test inconclusive pending further review due to the IA pressure increasing during the test.

The Sundry, originally issued February 19, 2002, was for continued water injection with tubing by inner annulus communication. The well no longer adheres to BP's Well Integrity Systems Policy and will remain shut-in until the communication has been repaired. A State witnessed MITIA for UIC compliance will be conducted once the repair is complete and the well is on injection. The application for Sundry cancellation form 10-404 is attached.

The MITIA failed and a leak rate of 12 GPM @ 2450 psi was established. A tubing tail plug was set and a CMIT TxlA passed to 2500 psi on 11/25/01. Recent events: > 03/16/00: MITIA FAILED, LLR 12 GPM @ 2450 psi. > 11/23/01: SL set TTP > 11/25/01: CMIT Passed to 2500 psi > 01/10/02: Pull plug This sundry request is to allow for continued injection of water. The following supports the request: - A CMIT-TxlA Passed on 11/25/01 to 2500 psi against a tubing plug, demonstrating competent production casing. - Pressures and injection rates will be monitored and recorded daily and checked for indications of a production casing leak. - A CMIT TxlA against a TTP will be conducted every 2 years to confirm production casing integrity. Proposed Action Plan 1. Allow well to continue water-only injection. 2. Perform combination MIT Tubing x IA against a plug every 2 years. 3. Record wellhead pressures and injection rates daily. 4. Submit a monthly report of daily pressures and injection rate. 5. Stop injection and notify the AOGCC if there is any indication of loss of production casing integrity.

Winton may have responded. Your proposal is acceptable to put the well back on water service. As usual, please add the well to the monitoring list. If you have an updated version of the wells on waiver according to the classification system you devised, I would appreciate a copy. Thanks.

A TTP was set and the well passed a CMIT TxIA to 2500 psi on 11/25/01. Current plans are to pull the TTP and submit sundry form 10-403 requesting a variance to continue injection with the known TxIA communication. I'd like to request verbal approval to put the well on injection pending approval of the written variance. Thanks and call if you have any questions.

INTRODUCTION Core Laboratories was requested to perform a core analysis study on behalf of Arco Alaska, Inc. for samples recovered from the DS 4-42 well from the North Slope, Alaska. Presented herein are the results of this study. iConventional cores cut with a bland mud were processed on site by Arco personnel. A service description and methodology are presented in section 1. The core analysis results and lithological descriptions for the horizontal plug samples are presented in section 2. A statistical summary and plots for the horizontal plug samples are in section 3. Section 4 contains vertical plug sample core analysis results and lithological descriptions. Vertical plug sample statistics and plots can be found in section 5. Section 6 contains copies of shipping and receiving transmittals. In conjunction with the report, the tabular results of the analysis are supplied on an IBM PC compatible diskette. We sincerely appreciate this opportunity to be of service and hope these data prove beneficial in the development of this reservoir.

The core was preserved using the aluminum inner core barrels. The barrels were marked and cut into three foot sections, and the open ends were covered with rubber capped and clamped. These aluminum barrel sections were then shipped to Core Laboratories' Anchorage facility. Conventional Core Processing i Upon arrAval at Core Laboratories Anchorage facility, the core barrels were placed in depth order, and surface core gamma logged. The core sections were removed from the aluminum sections, fit together, oriented, depth marked and double striped to maintain proper orientation. Horizontal and vertical plug points were then designated by Arco personnel. The plugs were then drilled, using brine as a coolant, and trimmed into right cylinders. The plug ends were placed in plastic bags and boxed. Upon completion of the plugging, the core was slabbed into two third and one third library sections, with appropriate depths being marked on both. One set of state chips were taken from the two third sections of cores 1 and 9. Both the one third and two third slabbed sections were then boxed according to depth. Core Photographs The two-third slabbed section of the cores were photographed. Approximately 15 feet of core appears in each photograph. Seven sets of visible spectrum flash light and four sets of ultraviolet light photographs appear in separate binders. Bedding Study A bedding study was performed on the core. Results of the study will be included in a separate report. Special Considerations The aluminum inner barrels containing the core samples were allowed to stand for a period of five days before plug poin~.s were chosen by Arco. This may have effected the water saturations. Laboratory procedures Dean-Stark Fluid Saturation Measurements Water was extracted from the samples by Dean-Stark technique using toluene. Samples were removed from the Dean-Stark and placed in toluene for hydrocarbon extraction aminimum of one day, or until no fluorescence was visible. Extracted samples were dried in a convection oven at 240 degrees F. for a minimum of 24 hours, and cooled in a desiccator to room temperature before porosity and permeability was measured. Saturations by Dean-Stark methods were calculated using Equations I and 2. Where' So : [((W1 - W2 - H20)/Do)/Vp] x 100 (1) Sw: [H20/Vp] x 100 So = Oil Saturations, Percent Sw = Water Saturation, Percent W1 : Natural Weight W2 = Extracted and Dried Weight H20: Extracted Water, Density Assumed 1.0 gm/cc Do : Density of Oil ~. : Pore Volume (2) Grain Density ~ Grain volume determinations were measured on all samples according to Boyle's Law utilizing the Extended Range Helium Porosimeter. Grain densities were calculated using Equation 3. Dg : Mg/Vg (3) Where: Dg = Grain Density Vg = Grain Volume Mg = Grain Mass Atmospheric Porosity All of the plug samples were measured for bulk volume by mercury displacement at ambient conditions. Porosity was calculated using Equation 4. P : [(VD-Vg) / Vb)] x 100 (4) Where: P: Porosity, Perrent Vb: Bulk Volume Vg : Grain Volume Atmospheric Permeability to Air Horizontal a~d vertical permeabilities were measured in a Hassler type core holder at a confining pressure of 400 psig.

Excess non-hazardous fluids developed from the well operations and as necessary to control the reserve pit fluid level will be pumped down the 7-5/8" x 10-3/4" annulus. The annulus will be left with a non-freezing fluid during any extended period. The annulus will be sealed with 300 sxs of cement followed by Arctic Pak. b. Minimum distances of wells within 200 ft. of the proposed well are: _o DS 4-06: 57' @ 2500' MD/TVD "DS 4-13: 77.50' @ 5300' MD/TVD o DS 4-05: 108' @ 3700' MD/TVD c. The drilling fluid program and surface system will conform to the regulations set forth in 20AAC25.003. d. Maximum surface pressure is based on BHP and a full column of gas to TD (0.10 psi/ft ). e. Based on previous logs on DS#4, no potential productive zones are anticipated above 3500' TVD. f. No potential hazardous levels of H2S are anticipated in this well.
