Attachments in Duplicate • .5?..) //-/,•3• 4-..:- _A • • To: Alaska Oil & Gas Conservation Commission From: Ryan Ciolkosz :ID biD CTD Engineer Date: November 4, 2015 Re: 09-18 Sundry Approval Sundry approval is requested to plug the 09-18 wellbore as part of the drilling and completion of the proposed 09-18A CTD sidetrack. History and current status: 06/01/91: RWO to mitigate IAxOA communication. Ran 7" L80 scab liner to get better injection conformance. Also ran 7" x 4.5" L80 tubing. After RWO, Z1 was frac'd (160k prop behind pipe) and Z4 frac'd (29.5k lbs prop behind pipe). 09-18 is a currently actively producing waterflood pattern in the central drill site 09 area of the field. Historically this well was perfed in zone 1 and 2 during the period of pre- production and has since had perfs in all 4 Ivishak zones during its long injection history. Currently injection is dominated by at least 90% of injection into the zone 3 with average injection rates of-10,000 bwpd prior to being shut-in in 2012. Wellwork was discussed to isolate zone 3 to re-direct injection into lower watercut zones (2 and 4) rather than side-track the well. However, the QCLL scab liner that is the most effective way to isolate the perfs, requires cement behind it to insure isolation. Previous experience with cement squeezes in zone 3 indicate that there is a reasonable chance that we would not be able to get cement all the way to the top of the liner(and would not be able to get complete isolation from zone Proposed plan: Drill a through tubing sidetrack with the Nordic 1 Coiled Tubing Drilling rig on or around March 10th, 2016. E-line service unit will mill XN Nipple, Set Posiset Plug to isolate perforations below and set - whipstock pre drilling rig. Nordic 1 will a mill a 3.80"window in the 7"x9-5/8" liner and drill a Zone 2&4 well to 10,313 MD. The lateral will be completed with a 3-1/2" x 3-1/4"x2-7/8" 13CR-80 liner which will be cemented and perforated. This Sundry covers plugging the existing 09-18 perforations via the 09-18A liner cement job or liner top packer set post-rig (alternate plug placement per 20 AAC 25.112(i)) and via posi-set plug. The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the current wellbore and proposed sidetrack is attached for reference.

If the"Abandon" or ✓` "Suspend" boxes are also checked, cross out that erroneous entry and initial it on both copies of the Form 10-403 (AOGCC's and operator's copies). 2 If the "Abandon" box is checked in Box 15 (Well Status after proposed Geologist / work) the initial reviewer will cross out that erroneous entry and initial then it on both copies of the Form 10-403 (AOGCC's and operator's copies). f/ Instead, check the "Suspended" box and initial that change. Drilling Engineer The drilling engineers will serve as quality control for steps 1 and 2. (QC) 3 When the Stat Tech receives a Form 10-403 with a check in the "Plug Stat Tech for Redrill" box, they will enter the Typ_Work code "IPBRD" into the History tab for the well in RBDMS. This code automatically generates a comment in the well history that states "Intent: Plug for Redrill." 4 When the Stat Tech receives any Form 10-407,they will check the Stat Tech History tab in RBDMS for the "Intent: Plug for Redrill" code (IPBRD). If present and there is no evidence that a subsequent re-drill has been COMPLETED, the Stat Tech will assign a status of SUSPENDED to the well bore in RBDMS no matter what status is listed on the 10-407. The Stat Tech will also change the status on the 10-407 form to SUSPENDED, and date and initial this change. If the Stat Tech does not see the "Intent: Plug for Redrill" comment or code, they will enter the status listed on the Form 10-407 into RBDMS. 5 When the Form 10-407 for the redrill is received, the Stat Tech will Stat Tech change the original well's status from SUSPENDED to ABANDONED. 6 The first week of every January and July,the Stat Tech and one of the Stat Tech Geologists will check the "Well by Type Work Outstanding" user query Geologist in RBDMS to ensure that all of the Plug for Redrill wells have been handled properly. At this same time, they will also review the list of suspended wells for accuracy. �r • • 1 O aJ Q 0 X co (O Q L o a N 0 v s s c oo I- a ra n O O p O >- a < • p 7 ,n ,� ,n in u� @ m oo v s -1 D „fL V , u '-' 4-' 1./1 N Q f.; W Y I W _ C7 al O A 7 w V) ✓, L C C t Orm NZJQ - N V - ' -. c rOa a) > z ,-- 0 ° o 0°- y '0 L ru L 6 0 0 0 0 0 0 0 C 0 O n w w w w W w w OA I- L.L.

Inspection AAI PBU DS9-18 Permit No. 77-39 Prudhoe dOil Pool FROM: Doug Amos Petroleum Inspector Wednesday MaY 23. !991: I traveled this date from Anchorage to AAI's PBU Dsg-18 well to conduct a BOPE walk-thru inspection on AUDI workover Rig No.4. As the attached AOGCC BOPE Walk-thru inspection form indicates, I found item 16 not in-compliance. I discussed this problem with AUDI rep Jim Gafney and he called his warehouse representative and was informed that the HCR valve could not be repaired locally and had to be sent to Houston Texas to be rebuilt. The valve is scheduled to be back on location by 6/5/91. I requested that Jim try to find a loaner valve until he recieved his original valve but he was unable to locate a valve that would fit his 3000# stack. The flare and vent line were installed and will be operational as soon as the HCR valve is installed. The manual valve needed to complete the flare/vent line system is currently being used in place of the HCR valve on the BOPE stack choke line. In summary, I conducted a BOPE Walk-thru inspection at AAI's PBU DS9-18 well on AUDI Rig No. 4. I found item 16 on the inspection form not in compliance . The HCR valve is being rebuilt and will be installed on or before 6/5/91. Attachment. 02-00lA (Rev. 6/89) 20/11/MEMO1.PM3 OPERATION: Drlg.

Injection Well 9-]8 Annular Communication Per Rule 7 Requirements of Area Injection Order No. 4 DISCUSSION: WAG well 9-18 has tubing X 9 5/8 communication when the well is on miscible injection. The 9 5/8 annulus pressure tracks normal WAG injection pressure of 2500 psi. When the 9 5/8" annulus is bled back, it builds at a rate of 75 psi/hour up to an estimated 2200 psi within 24 hours. Well was shut in on 12/9/89 for a 13 3/8 MIT to 2000 psi. On 12/14/89, the 9 5/8' annulus was successfully MIT'd to 2000 psi. ARCO plans to switch the well to seawater injection and continue to monitor the pressures. No additional work is planned unless a leak to water is identified. ,,,, AOGCC RESPONSE: Fill out Form 403 Sundry. Attach summary of history and proposed plan. Submit to C.V. Chatterton.

Describe Proposed or Completed Operations (Clearly state all pertinent details and give pertinent dates, including estimated date of starting any proposed work, for Abandonment see 20 AAC 25.105-170). Atlantic Richfield Company proposes to repair production tubing leak(s) in this well. There is a SSSV stuck at +11' below the tubing hanger at a possible tubing part. The SSSV will be recovered from the well and the 5½" production tubing string will be pulled. The well will be checked for possible 9-5/8" casing leaks and the 9-5/8" casing will be repaired as necessary. The well will be completed with new 5½" plastic coated tubing wi th gas lift mandrels. A 13-5/8" 5000 psi RSRRA BOP stack will be used on well work performed by the workover rig. The BOP equipment will be pressure tested each week and operationally tested each trip. A non-freezing fluid will be left in all uncemented annuli within the Permafrost interval. Necessary provisions for subsurface safety equipment will be run in the completion string. A 5000 psi WP wireline lubricator, tested to working pressure, will be used on all wireline work. The downhole safety valve will be installed and tested upon conclusion of the job.

A 5000 psi WP wireline lubricator, tested to working pressure, will be utilized with all wireline work. All perforations will be made with hollow carrier type guns at 4 shots per foot. Well will be flowed to a surge tank to recover load fluids and any produced well fluids. All recovered liquids will be retained in the surge tank, then trucked to the oily waste disposal facilities for disposal. Any produced gas will be vented to the atmosphere during perforating operations. The downhole safety valve will be installed and tested upon conclusion of job. Estimated Start Date: 2-9-78 ]6.
