PTD /1 -e. , • • Loepp, Victoria T (DOA) From: NSK Well Integrity Supv CPF3 and WNS <n2549@conocophillips.com> Sent: Friday, December 15, 2017 9:14 AM To: Loepp,Victoria T(DOA) Cc: Senden, R.Tyler Subject: CRU CD4-208 (PTD 211-060)IA Sustained Casing Pressure Follow Up Flag: Follow up Flag Status: Flagged Victoria, Alpine producer CRU CD4-208 (PTD 211-060)is being reported for sustained casing pressure of the IA exceeding 2000 psi as a result of an open gas lift mandrel pocket and deferred wellwork. The IA pressure previously increased above 2000 psi after the OV was intentionally pulled during planned wellwork. CPAI is reporting the well because the wellwork has been temporarily deferred for logistical reasons in addition to weather delays,and the IA pressure is expected to remain high(near 2450 psi at present) until further wellwork is commenced and completed. The well has 7",26 lb/ft, L-80 grade production casing with a burst pressure rating of 7240 psi. CPAI will continue to monitor the well's condition while a wellwork plan forward is progressed. Please let us know if you have any questions or disagree with this plan. Regards, Rachel Kautz/Travis Smith Well Integrity Supervisor,ConocoPhillips Alaska Inc.

Attachments: CD4-208A TIO plot.JPG;CD4-208A.pdf Follow Up Flag: Follow up Flag Status: Flagged Victoria- Alpine producer CD4-208A(PTD 211-060)was reported today with SCP of the IA. The IA was reported at 2038 psi. Operations attempted to bleed the IA but the pressure built back immediately. The well has 7"26Ibs L-80 pipe which has a pressure rating of 7240 psi. A plan forward is being formulated and slick line will start diagnostics as soon as reasonably possible. The well is currently shut in and will be until diagnostics are completed. Attached are the 90 day TIO plot and well bore schematic. Dusty Freeborn/Jan Byrne Well Integrity Supervisor ConocoPhillips Alaska, Inc.

We decided to not run a PBR with the second completion run because of the trouble we had stabbing back into the first PBR (both with the first upper completion run and a subsequent drift run on drill pipe). The second upper completion was run on 7/1 and the rig moved off on 7/2. I updated the schematic (attached)this morning to reflect the changes.

With the extensive trouble drilling this well doing the choke manifold test offline will minimize the BOP test period and get you back into the well sooner to run the 4.5" liner. Doing the choke test offline doesn't necessarily move up the start time on the BOP test though. I'm not sure how Mr Regg looks at that .... Normally the start time for the test is when the actual BOP are tested. But this well has some special circumstances. POOH safely (without swabbing) and start the BOP test as soon as possible. Regards, Guy Schwartz Senior Petroleum Engineer AOGCC 793-1226 (office) 444-3433 (cell) From: Winfree, Michael Alex(Jr.) [mailto:Michael.A.Winfree@conocophillips.com] Sent: Friday, June 24, 2011 2:11 PM To: Schwartz, Guy L (DOA) Subject: CD4-208A BOPE Test(PTD# 211-060) Guy, Per our conversation, we are currently pulling out of the hole at 7,000' MD with pumps. Our BOPE test is due today and we anticipate laying down the BHA by 10:00 pm and initiating our BOPE test before midnight. As we pull out of the hole and it becomes likely that we may not make the timing stated above, CPAI proposes initiating the BOPE test on the choke manifold prior to midnight while finishing the trip out of the hole. Once out of the hole and the choke manifold tested, a test plug can be set and the full BOPE test will be performed before running our lower completion. Current timing suggests we will be out of the hole and able to start our test prior to midnight, but since the timing is tight, I wanted to get preapproval to test the choke offline since this will be happening well after business hours. Please let me know if you need additional information regarding this BOPE test. Thanks, -Mike Mike A.

The new plan is to run a Baker Premier packer higher up in the hole and tie it to the liner with a long tubing tail. The connection at the liner will not be a hydraulic barrier.

On CD4-208A,after reaching casing point at 11,704' MD,the drill string packed off and tight hole conditions were observed on the subsequent wiper trip 4 stands off bottom. The drilling BHA was pulled out of the hole and the attempt to recover the hole v with a clean out assembly was unsuccessful. A sundry was submitted and approved to abandon the wellbore. The 7"intermediate casing shoe lands 1,334' MD away from the original permitted 7"shoe location. The primary reason for the sidetrack is hole instability in the lower shales, but based on the sand observed at the original casing point,the shoe location e- ms was moved southeast to an area expected to have a more favorable sand presence. 44e-- CD4-208A (`CD4-208A is still planned to be a horizontal Alpine C sand producer.

Ensure good hole cleaning by pumping regular sweeps and maximizing fluid annular velocity. Maintain mud weight at or 11.0 ppg for lower shale stability. 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 production interval will be drilled with a MOBM drill-in fluid. The fluid will consist of 80/20 OWR. Base oil is LVT-200 mineral oil, the internal phase will consist of 33% w/w CaCl2 brine with emulsifiers and wetting agents. Sized calcium carbonate will be used as a bridging agent for proper filter cake building and fluid loss control.

CD4-208A was planned to be a horizontal Alpine C sand producer. The 8-3/4" intermediate hole was sidetracked and drilled to a depth of 11,703' MD/7,376' TVD. Hole conditions required a clean out ran and due to Milluveach instability, the cleanout BHA was unable to reach TD following a pack off event and tight hole conditions. The intermediate hole appears to have collapsed around 10,613' MD which is in the Kalubik shale. The decision was made to pull out of hole and plug back with cement. The new plan is to isolate,CD4-208A with three cement plugs to isolate the Alpine/Kuparuk, and Nanuq reservoirs. An abandonment/kick off plug will be placed on top of an ECP cementing tool at 6,150' MD. Upon isolation the original well, CD4-208A will maintain API: 50-103-20517-01-70 and named CD4-208APB1. The new well,will become CD4-208A(API: 50-103-2517-01-00) Please find attached: • Form 10-403 Application • Plan forward • Proposed final well schematic If you have any questions or require further information, please contact Nina Anderson 265-6403 or Mike A.

Guy Sent from my iPhone On May 29, 2011, at 11:41 PM, "Robertson, Ryan G" <Ryan.G.Robertson@conocophillips.com>wrote: Guy, As per your discussions with Mike Winfree Jr... Shale stability issues in the lower portion of the 8.75" intermediate hole on CD4-208A have prevented forward progress on the well as planned. Initial hole problems occurred on May 26th while tripping out of the hole after TD was reached at 11,703' MD. A subsequent clean out run performed today indicated that the hole could not be recovered past 10,618' MD due to deteriorated hole conditions. As a result, CPAI proposes to abandon the intermediate hole section and sidetrack a new 8.75" intermediate hole. Prior to sidetracking operations, three separate abandonment plugs will be set, with the base of the lowest plug set at 10,618' MD. Each plug is planned to be 700' MD in length, bringing the top of the third plug to 8,518' MD, roughly 450' MD above the top of the Nanuq sand. This sand is the upper most hydrocarbon bearing formation that will be abandoned. The lower Kuparuk C and Alpine C sands will be isolated from above with this series of plugs. After setting the third plug, the cement stinger will be used to confirm final plug height by tagging up after the cement has gained sufficient strength. Once the lower intermediate is abandoned, an ECP cementer will be ran to 5,850' MD, and a kick off plug will be set to allow the well to be sidetracked at 6,000' MD. Please see attached schematic and don't hesitate to call or email with any questions.

CD4-208Awp19 request for verbal approval (PTD 211-oho) Mike, You have verbal approval to proceed with your sidetrack as outlined below and depicted in the attached directional plan. Please submit a revised PTD as soon as possible. Guy Schwartz Senior Petroleum Engineer AOGCC 793-1226 (office) 444-3433 (cell) From: Winfree, Michael Alex(Jr.) [mailto:Michael.A.Winfree@conocophillips.com] Sent: Wednesday, June 01, 2011 2:59 PM To: Schwartz, Guy L(DOA) Subject: CD4-208Awp19 request for verbal approval Guy, Attached is the proposed directional profile for the upcoming sidetrack operations at CD4-208A. After reaching casing point at 11,704' MD, the drill string packed off and tight hole conditions were observed on the subsequent wiper trip 4 stands off bottom. The drilling BHA was pulled out of the hole and the attempt to recover the hole with a clean out assembly was unsuccessful. A sundry was submitted and approved to abandon the wellbore. The attachment shows the directional profile of the proposed sidetrack. The 7" intermediate casing shoe lands 1,334' MD away from the original permitted 7"shoe location. The primary reason for the sidetrack is hole instability in the lower shales, but based on the sand observed at the original casing point, the shoe location was moved southeast to an area expected to have a more favorable sand presence. Current operations on the rig are running in the hole with Baker ECP to kick off depth. Plan forward is to set kick off plug on top of the ECP and, pending AOGCC approval, kick off cement plug and re- drill the 8-3/4" intermediate interval. The revised Permit to Drill application will be delivered to the AOGCC office tomorrow (6/2/2011). ConocoPhillips requests verbal approval to continue operations as described above. Please let me know if you need additional information regarding the sidetrack operations at CD4-208A to process this request.

The new plan is to run a Baker Premier packer higher up in the hole and tie it to the liner with a long tubing tail. The connection at the liner will not be a hydraulic barrier.

The intended spud date for this well is 5/6/2011. It is intended that Doyon Rig 19 be used to drill the well. CD4-208 was plugged and abandoned with cement per the Sundry numbers 311-053 for pre-rig work and 311-090 for rig de-complete. ^ CD4-208A is planned to be a horizontal Alpine C sand producer. The 8-3/4"intermediate hole will be drilled off of a cement kick-off plug out of the existing 9-5/8"surface casing to a depth of 11,482' MD/7,360'TVD. After setting 7"intermediate casing,the 6-1/8" horizontal section will be drilled and the well completed as a producer with blank/perforated pup liner. The well will be flowed back to mitigate formation damage. It is expected that the K2(Qannik)sand will be considered a significant hydrocarbon bearing zone. A stage tool will be run to cement off the Qannik with 500'of cement above and below the interval. Lead cement will be pumped,then the stage tool will be opened and a second cement job pumped to isolate the Qannik. This will leave a mud gap between the two stages. The Nanuq formation will be cemented a minimum 500'above top of the sand. 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 drilling fluids program summary. 4. Proposed completion diagram 5. Pressure information as required by 20 ACC 25.035(d)(2). 6.

Ensure good hole cleaning by pumping regular sweeps and maximizing fluid annular velocity. There is potential for lost circulation, particularly after the reservoir is penetrated. Maintain mud weight at or below 9.8 ppg and be prepared to add loss circulation material. High mud weights are required for lower shale stability. 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 production interval will be drilled with a MOBM drill-in fluid. The fluid will consist of 80/20 OWR. Base oil is LVT-200 mineral oil, the internal phase will consist of 33% w/w CaCl2 brine with emulsifiers and wetting agents. Sized calcium carbonate will be used as a bridging agent for proper filter cake building and fluid loss control.

Drilling below surface casing (9 5/8") ASP= [(FG x 0.052)—0.1] D = [(14.5 x 0.052)—0.1] x 2440 = 1138 psi OR ASP = FPP—(0.1 x D) =3188—(0.1 x 7360') =2452 psi 3. Drilling below intermediate casing (7") ASP = FPP—(0.1 x D) =3188—(0.1 x 7360) =2452 psi • OFGtNAL Well Proximity Risks: Directional drilling/collision avoidance information as required by 20 ACC 25.050 (b) is provided in the attachments. There are no wells that fail major risk analysis. The closest well to the proposed CD4-208A wellpath is CD4-12 with an ellipse separation of 102' at—5,200' MD. Drilling Area Risks: Reservoir Pressure: Offset injection has the potential to increase reservoir pressure over predicted, • although this is highly unlikely, the rig will be prepared to weight up if required. Lower Shale Stability: High mud weights in the intermediate will require higher mud weights to stabilize. Standard LCM material and well bore strengthening pills are expected to be effective in dealing with lost circulation if needed. 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 CD4-208A will be injected into a permitted . annulus on CD4 pad or the class 2 disposal well on CD1 pad. The CD4-208A surface by intermediate casing annulus will be flushed with 300 bbls of fresh water prior to freeze protecting with diesel to 2000' TVD. The significant hydrocarbon zones are the Alpine, Kuparuk, Nanuq and the Qannik reservoir. There will be 500'of cement above the top of the Qannik reservoir. Upon completion of CD4-208A 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. 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)*(2594') + 1,500 psi = 3,118 psi Pore Pressure = 1,128 psi Differential =3056— 1128 = 1,990 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 9-5/8" 40 L-80 3 BTC- Mod 3,090 psi 2,626 psi 5,750 psi 4,887 psi 7" 26 L-80 3 BTC-Mod 5,410 psi 4,599 psi 7,240 psi 6,154 psi CD4-2O8A Drilling Hazards Summary (to be posted in Rig Floor Doghouse Prior to Spud) (See Well Plan Attachment: Detailed Risk Information for further discussion of these risks) 8-3/4" Hole / 7" Casing Interval Event Risk Level Mitigation Strategy Abnormal Pressure in low BOPE drills, Keep mud weight above 9.6 ppg.
