From:Smith, Travis T To:Loepp, Victoria T (OGC) Cc:Earhart, Will C Subject:CRU CD4-23 (PTD#210-067) High IA Pressure Date:Tuesday, December 28, 2021 4:44:46 PM Attachments:CD4-23 90-day TIO.pdf CD4-23.pdf Victoria— CRU producer well CD4-23 (PTD#210-067) has exhibited elevated IA pressure in excess of 2000 psi. The well is currently shut-in due to downhole fill issues and awaiting intervention. The IA pressure is currently at 1703 psi after having been bled. The production casing is 7-5/8” 29.7# L80 with a burst rating of 7900 psi. DHD performed a shut-in TIFL that failed. Our next step is to pursue diagnostics and troubleshooting with slickline—if Sundry paperwork is required for a fix, we will submit that at the appropriate time. A 90-day TIO and well schematic are attached. Please let me know if you have any questions or disagree with the plan.

Each of these wells was found to have a void in the conductor. These voids were filled with cement and corrosion inhibitor, engineered to prevent water from entering the annular space. As per previous agreement with the AOGCC,this letter and spreadsheet serves as notification that the treatments took place and meets the requirements of form 10-404, Report of Sundry Operations. The corrosion inhibitor/sealant was pumped March 13-15 and March 27-28, 2011. The attached spreadsheet presents the well name,top of cement depth prior to filling, and volumes used on each conductor. Please call MJ Loveland or Perry Klein at 907-659-7043, if you have any questions. Sincerely, MJ Loveland ConocoPhillips Well Integrity Projects Supervisor i ConocoPhillips Alaska Inc.

The following are brief descriptions of the operations related to the well bore naming question: Drilled out surface shoe and TD'd intermediate Could not get casing to bottom Pulled casing and laid it down Cleanout run was unsuccessful Plugged back with cement and sidetracked. The plugged back well bore will be CD4-23PB1 API Suffix-70 Drilled out intermediate and had excursion into unstable shale Pulled up and open hole side track to isolate shale interval This well bore with the unstable shale will be CD4-23PB2 API Suffix-71 The lateral that we just TD'd will be designated CD4-23 API Suffix-00 Please advise if this is the correct naming convention for the respective wellbores.

Page 1 of 1 Subject: FW: INTENT PLUG for RE-DRILL WELLS: Corrected From: Davies, Stephen F (DOA) Sent: Monday, February 08, 2010 10:52 AM To: Foerster, Catherine P(DOA); McMains, Stephen E(DOA); Schwartz, Guy L(DOA); Saltmarsh,Arthur C (DOA);Aubert, Winton G (DOA) Subject: RE: INTENT PLUG for RE-DRILL WELLS: Corrected Revised procedure with an additional step per Cathy's comment: INTENT PLUG for RE-DRILL WELLS (IPPRD)Type Work Code in RBDMS 1. When a Form 10-403 is submitted requesting approval to plug a well for redrill, the initial reviewer(Art or Steve D.) will check to make sure that the "Plug for Redrill" box in the upper left corner of the 403 form is checked. If the "Abandon" box is checked, we will cross that erroneous entry out and initial it on both copies of the Form 10-403 (AOGCC's and operator's copies). 2. On the Form 10-403 if"Abandon" is checked in Box 15 (Well Status after proposed work), Art or Steve D. will cross that erroneous entry out and initial it on both copies of the Form 10-403 (AOGCC's and operator's copies). Instead, we will check the "Suspended" box. Guy and Winton will serve as quality control for steps 1 and 2. 3. When Steve McMains receives the Form 10-403 with a check in the "Plug for Redrill" box, he will enter the existing code "IBPRD" into RBDMS. This code automatically generates a comment under the History tab stating "Intent: Plug for Redrill." 4. When Steve McMains receives any Form 10-407, he will check the History tab in RBDMS for this comment. If he sees the "Intent: Plug for Redrill" code, and cannot find any evidence that a subsequent re-drill has been COMPLETED, he will assign a status of SUSPENDED to the well bore in RBDMS, no matter what status is listed on the 10-407. Steve will also change the status on the 10-407 form to SUSPENDED, and will date and initial his change. If Steve does not see the "Intent: Plug for Redrill" comment or code, he will enter the status listed on the Form 10-407 into RBDMS. 5. When the Form 10-407 for the redrill is received, Steve M.will change the original well's status from suspended to abandoned. 6. The first week of every January and July, Steve M. and Steve D. will check the "Well by Type Work Outstanding" user query in RBDMS to ensure that all of the Plug for Redrill wells have been handled properly. At this same time, Steve M. and Steve D. will also review the list of suspended wells for accuracy.

After drilling the 9-7/8" intermediate hole section to TD at 11,987' MD, we were unable to get casing to bottom. The 7-5/8"string could not be worked past 10,495' MD. A decision was made to pull casing and make a cleanout run. The cleanout BHA could not be worked past 10,560' MD. The hole was packing off and required some Page 2 of 2 overpull to move the string. Currently we are pulling out of the hole with our clean out BHA and are preparing to pick up a cement stinger and set the cement plugs as described in the attachment, pending the states approval of our plug strategy.

The intended spud date for this well could be 06/01/2010. It is intended that Doyon Rig 19 be used to drill the well. After setting 7-5/8" intermediate casing, the horizontal section will be drilled and the well completed with tubing and slotted liner as an Alpine C sand producer. At the end of the rig work program, CD4-23 will - be flowed back for 2-3 days to mitigate reservoir damage. The well will then be closed in awaiting completion of well work and facilities connection that will allow the well to be placed on production. It is expected that the K2 (Qannik) sand will be considered a significant hydrocarbon bearing zone. After running 7-5/8" casing, it is planned to pump lead cement, then open a stage tool and pump a second cement job to isolate the K2 with 500' of cement above and below the interval. This will leave a mud gap between the two stages. It is requested that a waiver of the diverter requirement under 20 AAC 25.035 (h)(2) is granted. At CD4, there has not been a significant show of shallow gas or gas hydrates through the c surface hole interval. Please find attached the information required by 20 ACC 25.005 (a) and (c) for your review. Pertinent information attached to this application includes the following: 1. Form 10-401 Application for Permit to Drill per 20 ACC 25.005 (a). 2. A proposed drilling program. 3. A proposed completion diagram. 4. A drilling fluids program summary. 5. Pressure information as required by 20 ACC 25.035 (d)(2). 6. Directional drilling/collision avoidance information as required by 20 ACC 25.050(b). Information pertinent to the application that is presently on file at the AOGCC is: 1. Diagrams of the BOP equipment, diverter equipment and choke manifold lay out as required by 20 ACC 25.035 (a) and (b). 2. A description of the drilling fluids handling system. 3.

Move rig off. Well Proximity Risks: Directional drilling/collision avoidance information as required by 20 ACC 25.050 (b) is provided in the following attachments. CD4-24 is the nearest existing well to CD4-23wp10. Ellipse to ellipse separation is 4.57' at 700' MD. AOR No other wells within the Alpine pool exist within a 1/4 mile radius of the planned production zone on CD4-23wp10. . CD4-24 is the closest well within pool at a distance of 1797'. Within a quarter mile of CD4-23wp10, the well path of CD4-24 crosses at a depth greater than the pool. The colored Quarter Mile View plot along with the Section and Plan view plots illustrate this and can be found within the Sperry directional plan on pages 32 -34. Drilling Area Risks: There are no high-risk events. Lost circulation: Faulting within the Alpine reservoir section is considered to be the most likely cause of lost circulation. Standard LCM material is expected to be effective in dealing with lost circulation. Additional care and attention will be given to the higher potential of inducing a kick when drilling horizontally as opposed to vertically. Good drilling practices will be stressed to minimize the potential of taking swabbed kicks. Annular Pumping Operations: Incidental fluids developed from drilling operations on well CD4-23 will be injected into a permitted annulus on CD4, or the class 1 disposal well on CD1 pad. The CD4-23 surface/intermediate casing annulus will be flushed with 300 bbls of fresh water prior to freeze protecting with diesel to 2000'TVD. The only significant hydrocarbon zone is the Qannik reservoir and there will be 500' of cement fill above the top of the Qannik as per regulations. Upon completion of CD4-23 form 10-403, Application for Sundry Operations, will be filed. Annular pumping of fluids occurring due to drilling operations, per regulation 20 AAC 25.080, could then begin once properly permitted. As stated above, any zones containing significant hydrocarbons will be isolated prior to initiating annular pumping. There will be no USDW's open below the shoe or potable/industrial water wells within one mile of the receiving zone. Reference the enclosed directional drilling plan for other formation markers in this well. Surface casing will be set near the base of the Schrader Bluff Formation (C-40). These 450-500'thick shales are part of the Colville Group and are known to provide vertical barriers to fluid flow in other areas. The maximum volume of fluids to be pumped down the annulus of this well will not exceed 35,000 bbl without the specific permission of the AOGCC. Fluid densities will range from diesel to a maximum of 12.0 ppg for drilling fluid wastes. Using 12.0 ppg fluid and the rig's specified maximum pumping pressure of 1,500 psi for annular injection, the maximum pressure at the surface casing shoe is estimated by: Max Shoe Pressure = (12.0 ppg) *(0.052) * (Surf. Shoe TVD) + 1,500 psi = (12.0 ppg) * (0.052) *(2400') + 1,500 psi = 2997 psi Pore Pressure = 1,086 psi Therefore Differential =2997— 1086 = 1911 psi. The internal casing pressure is conservative, since frictional losses while pumping have not been taken into consideration. The surface and intermediate casing strings exposed to the annular pumping operations have sufficient strength by using the 85% collapse and burst ratings listed in the following table: Wt Connection 85%of 85% of OD (ppf) Grade Range Type Collapse Collapse Burst Burst 10-3/4" 45.5 L-80 3 BTC-M 2480 2108 psi 5210 psi 4428 psi 7-5/8" 29.7 L-80 3 BTC-M 4790 psi 4071 psi 6890 psi 5856 psi DRILLING FLUID PROGRAM SPUD to Intermediate hole to 7- Production Hole 10-3/4"surface casing 5/8— casing point—9-7/8" Section—6 3/4" point- 13-1/2" Density 8.8—9.6 ppg . 9.6— 10.0 ppg • 8.8-9.2 ppg • • PV 10—25 10—15 YP 20—60 15—25 25—30 Funnel Viscosity 100—200 Initial Gels 4—8 10— 15 10 minute gels <18 12 -20 API Filtrate NC— 10 cc/30 min 4— 12 cc/30 min (drilling) HPHT Fluid Loss at 160 12 - 14 cc/30 min PH 8.5-9.0 9.0- 10.0 9.0-9.5 KCL 6 % Surface Hole: A standard high viscosity fresh water/ gel spud mud is recommended for the surface interval. Keep flow line viscosity at±200 sec/qt while drilling and running casing. Reduce viscosity prior to cementing. Maintain mud weight< 9.6 ppg by use of solids control system and dilution where necessary. Intermediate Hole Section: Fresh water gel / polymer mud system. Ensure good hole cleaning by pumping regular sweeps and maximizing fluid annular velocity. There is potential for lost circulation, particularly after the Nechelik is penetrated. Maintain mud weight at or below 9.8 ppg and be prepared to add loss circulation material. Good filter cake quality, hole cleaning and maintenance of low drill solids (by diluting as required) will all be important in maintaining wellbore stability. Production Hole Section : The horizontal interval will be drilled with a M-I Flo-Pro drill-in fluid. The base fluid will consist of 6% KCI, with ± 30PPB calcium carbonate bridging material to minimize formation damage. Flo-Vis Polymer and Dual-Flo starch will be used for viscosity and fluid loss control respectively.

PROCEDURE FOR CALCULATING ANTICPATED SURFACE PRESSURE (ASP) ASP is determined as the lesser of 1) surface pressure at breakdown of the formation casing seat with a gas gradient to the surface, or 2) formation pore pressure at the next casing point less a gas gradient to the surface as follows: 1) ASP = [(FG x 0.052) -0.1]D Where: ASP =Anticipated Surface pressure in psi FG = Fracture gradient at the casing seat in lb/gal 0.052 = Conversion from lb./gal to psi/ft 0.1 = Gas gradient in psi/ft D =true Vertical depth of casing seat in ft RKB OR 2) ASP = FPP—(0.1 x D) Where; FPP = Formation Pore Pressure at the next casing point ASP CALCULATIONS 1. Drilling below conductor casing (16") ASP = [(FG x 0.052)—0.1] D = [(10.9 x 0.052)—0.1]x 114 = 53 psi OR ASP = FPP—(0.1 x D) = 1086—(0.1 x 2400') = 846 psi 2. Drilling below surface casing (10-3/4") ASP= [(FG x 0.052)—0.1] D = [(14.5 x 0.052)—0.1] x 2400 = 1570 psi OR ASP= FPP—(0.1 x D) = 3355—(0.1 x 7415) = 2614 psi 3.
