The well will be shut in and freeze protected. DHD will perform initial diagnostics today including pack off tests and a MITIA after which wireline diagnostics will be performed if necessary. If initial diagnostics pass, CPAI plans to bring the well back on injection for a 30 day monitor period. The proper paperwork for continued injection or corrective action will be submitted once the path forward has been determined. A wellbore schematic and 90 day TIO plot is attached.

(CPAI) notified the Alaska Oil and Gas Conservation Commission (AOGCC) of a potential improper injection at the KRU Drillsite 1B into well WSW-05. WSW-05 is a permitted Class II disposal well authorized and operating in accordance with AIO 2C. After areview of the events and details surrounding the origin and classification of the waste, and the ultimate disposal in WSW-05, AOGCC has determined that improper Class II injection did not occur. As a result, by copy of this letter, the AOGCC refers this to the EPA Region 10 office for a determination as to any potential investigation and / or enforcement action relating to this matter.

If the notice was mailed, then the period of time shall be 23 days. An application for reconsideration must set out the respect in which the order or decision is believed to be erroneous. The AOGCC shall grant or refuse the application for reconsideration in whole or in part within 10 days after it is filed. Failure to act on it within 10 days is a denial of reconsideration. If the AOGCC denies reconsideration, upon denial, this order or decision and the denial of reconsideration are FINAL and may be appealed to superior court. The appeal MUST be filed within 33 days after the date on which the AOGCC mails, OR30 days if the AOGCC otherwise distributes, the order or decision denying reconsideration, UNLESS the denial is by inaction, in which case the appeal MUST be filed within 40 days after the date on which the application for reconsideration was filed. If the AOGCC grants an application for reconsideration, this order or decision does not become final. Rather, the order or decision on reconsideration will be the FINAL order or decision of the AOGCC, and it may be appealed to superior court. That appeal MUST be filed within 33 days after the date on which the AOGCC mails, OR30 days if the AOGCC otherwise distributes, the order or decision on reconsideration. In computing a period of time above, the date of the event or default after which the designated period begins to run is not included in the period; the last day of the period is included, unless it falls on a weekend or state holiday, in which event the period runs until 5:00 p.m. on the next day that does not fall on a weekend or state holiday.

The subsequent LDL showed what appeared to be a leak just below the isolation sleeve covering the jet pump profile at 3078' and there was suspicion of a potential leak higher in the tubing. The plan was to pull and reset the isolation sleeve to facilitate further diagnostics, but after the isolation sleeve was reset an MITIA passed (10-426 attached).

Because the Alaska Disposal and Reuse Guide (the "Red Book") does not specifically address the operation as it was performed, we conducted a review of the matter. As promised in our earlier notification, we hereby provide you a summary of our review. Description: On the night of February 3, 2018, 24-hour coil tubing unit operations began on well 1J-101 to perform a nitrified foam clean out of the A and B laterals. Nitrified foam is needed for this work because of the low bottom hole pressure of West Sak wells; the foam lightens the fluid column and helps get the sand returns to surface. The well work request documentation included a procedural step to pre-load the returns tanks with 50 barrels of diesel to be used as a breaker pill for the foam returns during the clean out process. The clean out began February 3, 2018 with pumping nitrogen and seawater mixed with a foaming agent. By the time the first load of returns was ready to be hauled off, the Kuparuk hydrocarbon recycle facility was closed for the day. A decision was made to send the load to 1B Class II disposal. On February 6, 2018, the foam cleanout continued, and a constant stream of returns was generated, resulting in three more loads of returns being hauled to 1B Class ll disposal. Altogether, the four loads of returns taken to the 1B Class II disposal contained a total of 200 barrels of diesel that had been pre-loaded into the returns tanks. The diesel used was low end point diesel manufactured at the Kuparuk topping plant and had not been previously used down-hole for freeze protection, or used in any other way. • • The remaining loads of returns, generated from the early morning of February 7 through job completion on February 9, were delivered to hydrocarbon recycle, rather than the 1B Class II disposal well. Discussion: Diesel was used to treat the foam and condition the returns for handling and disposal. Nitrified foam clean outs can result in foam overflowing from the returns tank, but diesel breaks the foam and ensures the returns take the form of a pumpable liquid. The returns must be in the form of a pumpable liquid in order to be transferred from the returns tank to a vac truck, and then from the vac truck to injection well and into the approved disposal zone at (or below) the approved injection pressure. The Alaska Disposal and Reuse Guide (the "Red Book") does not specifically address in the disposal and reuse tables the inclusion of a conditioning agent such as diesel that is used to serve a necessary purpose in the well operation. The lack of explicit guidance in the Red Book on this issue led to our precautionary decision to provide notice of this injection to the AOGCC. Based on our review, we believe the diesel was used appropriately as a foam breaker to mitigate against the risk of overflow from the tank and disposal well. The use of the diesel was intrinsic to and uniquely associated with the Kuparuk River Unit operations. Accordingly, our determination is that disposal of the returns in a Class II disposal well was consistent with the Red Book and applicable permit and regulatory requirements. Actions: To benefit from the learnings of this review, and to promote clarity going forward, CPAI will take the following actions. 1. We will clarify the use of conditioning fluids for Class II disposal. This may be done with a revision to the Red Book, in a separate guidance document, or in another form of documentation. 2. We will submit our proposed clarification of the use of conditioning fluids with the AOGCC for review. 3. We will review our Well Work Request form to consider including a section on Fluids Recycle/Disposal. 4. We will review the need for a night operator to operate with KRU fieldwide superintendent to keep the hydrocarbon recycle facility open when 24-hour wellwork operations are occurring. This may allow for additional hyrdocarbon recycleof fluids otherwise eligible for processing.

I wanted to verify diesel was our preferred fluid for step rate tests with our field drilling supervisor before I responded,which is why you received the email today. From now on you can consider me the single point of contact for this project, I apologize for the confusion. WSW-02—PTD 182-137 1. MITIA's in 1989, 1993 and 1997 passed. Well was used to dispose of pigging fluid in 1991 and was not in use after 1991. Well passed MITIA to 1700 psi on 4/27/13 and passed a state witnessed MITIA to 1710 psi on 5/9/13. 2. Plan forward for this well is to complete further investigation to see if it will be an adequate slurry injection well, this is the only well we are considering for slurry injection at this time, the rest of the WSWs will remain class 2 fluid disposal wells. Once the sundry is approved we plan to use this well to inject class two fluids while monitoring other well pressures on 1B pad to confirm that they are not in communication with this well. We would like to perform a step rate test before we begin injection,our preferred fluid is diesel. 3. We are currently verifying cement bond logs of surrounding 1B wells and confirming upper shale zone confining pressures from previous modeling results. We are currently working on a plan to monitor surrounding wells while using WSW-02 as a class 2 fluid disposal well to confirm that it will be an adequate slurry injector. We plan to submit all of our results when our studies are complete and the sundry requesting slurry service is submitted. WSW-03—PTD 182-142 1. MITIAs in 1988, 1993 and 1997 passed.

If these wells are to be used for slurry injection,then the appropriate hydraulic modeling should be performed to establish the injection pressure and rate limitations to avoid fracturing the well into the confining layers. This would then be included into the MIT test pressure consideration. The MIT you speak of should be performed to the maximum anticipated surface pressure, 1500 psi, or 0.25 psi/ft x packer depth TVD ft whichever is greater. As per Guidance Bulletin 10-002 MIT,Shut in Wells "The Commission's preference is to witness an MIT while a well is actively injecting and wellbore conditions (rate and temperature) are stable. If the well is in a short-term shut-in status when the MIT is due,the Commission should be notified and provided an alternate date for testing based on when injection will be recommenced. Injection wells that are shut in long-term (undetermined when injection will restart) need not be tested until they are ready to recommence injection. In lieu of an MIT for the long term shut-in well, the operator must provide to the Commission a quarterly graph of tubing, inner annulus and outer annulus pressures." Please schedule MITs with the inspectors at your earliest convenience,to the maximum that you feel is adequate for your path forward.

The purpose of the step rate test is to determine the injectivity of the existing wellbore. The anticipated length of the test is 6-12 hours. (Verbal approval was granted by Commissioner Lonnie Smith, June ~7, 1988) These wells were drilled for use as creataceous source water in Increment 1 Waterflood at Kuparuk River Field. They are completed in the Upper Ugnu. The intent is to convert these well. s from producers to injectors to dispose of non-hazardous, Class II reserve pit water. Recent correspondance with the EPA has confirmed the Class II classification of reserve pit water. Subsequent Sundry Notices will be filed for the conversion of these wells. No BOP will be used for the proposed work. The estimated BHP in the Upper Ugnu is 1000 psi. No workover fluids are required.

Describe proposed program: ARCO Alaska, Inc., proposes to drill a Kuparuk River Field, Kuparuk River Unit, water source well to approximately 3960' MD, 3424' TVD. Selected intervals will be logged. A 20" 2000 psi annular diverter will be installed on the 16" conductor while drilling the surface hole. A 13-5/8" RSRRA BOPE stack will be installed on the 10-3/4" surface pipe. It will be tested upon installation and weekly thereafter. Test pressure will be 3000 psig (1800 psi for annular). Expected maximum surface pressure will be 1537 psig based on warming of a gas bubble rising at constant volume. A 3-1/2" gravel pack screen will be run to + :3100' TVD and gravel packed. The interval will be produced by a downhole pump set above the gravel pack packer on 3-1/2" 9.2# J-55 BUTT. TBG. Non-freezing fluids will be left in uncemented annuli through the permafrost interval. Selected intervals will be perforated within the Ugnu formation and reported on subsequent reports. -23.

WSW No. 4 is vertical to 700' and WSW No. 5 will be vertical to 750'. At these points, the areas of uncertainty of the individual well surveys.would be 24' and 26' in diameter, respectively. This is based upon typical field-observed accuracies for the surveying tools utilized. Assuming a worst-case situation, the areas of uncertainty would not intersect or overlap one another. Further, after reaching these points, the subject wellbores are directionally drilled at diverging angles further widening the margin of safety. In addition, please note that the proposed WSW #5 crosses Well 1B-5 at a distance of 60' @ 1527~TVD. At this depth, the areas of uncertainty of the individual well surveys would have maximum, diameter of 54' for both wells. Even assuming the worst-case situation, the areas of uncertainty do not intersect. In light of the above, we feel we can safely drill Water Source Well No. 5 and avoid proximity problems with the adjacent wellbore. 12 ~ O- MARKER :590' 1 - '~' ..... zoO-Jo' 261' J ~j~- WS- IP_.O' PIT I ~~t 'iZO' '~,WS-3 B-6 -~- RESERVE ~,WS-4 ~,WS-6 ~o' ~zd -(~ )-WS..7 6~ )' ~4 ~ ~ ~ws, e T 120' =: 530' B-2 -~ 120' ! 60' lB-Ii GI-~ -~WS-9 80' 160' ~ O~ _ I O' ...... ~ 0 ~R~ER ~ Revised WS-8 Thru WS-12 8-12-82 c.l.f.
