This was for the plugback of PBU L2-21A in preparation of redrilling as PBU L2-21 B. Slickline unit tagged the top of cement at 10,203 feet (slickline measured depth) with a bailer; they set down with 150 lbs on the plug. In the process, they got a sample of the cement and pulled out of the hole. Little Red was all rigged up and we did a pressure test on the tubing. BPXA wanted a - minimum of 2500 psi.

L2-21 was originally drilled in 1985, worked over in 2004, and sidetracked with CTD in 2004. The Lisburne A lateral is at the end of its useful life with no viable remaining Lisburne targets. The well is no longer competitive due to low oil production, and the well has no future wellwork options. The well has not been consistently online since 2004 and is currently cycled for 3-5 days every 1-2 months. The well has passed integrity and is fit for a sidetrack. • Scope of Work: The primary objective of this wellwork is to abandon the Lisburne lateral L2-21A by cementing the formation through the slotted liner completion and by achieving zonal isolation between the Lisburne and Ivishak reservoirs. This work is in support of a planned Ivishak sidetrack from the L2-21 parent wellbore. Proposed plan: L2-21 B will be drilled from well L2-21A by the Nabors CDR 2 Coiled Tubing Drilling rig on or around August 1st, 2017. The L2-21B sidetrack will exit through the existing 4-1/2" tubing in the cemented 4-1/2"x 9-5/8" annulus above the production packer. The sidetrack will kick off in the Ivishak targeting, Ivishak reserves. The proposed sidetrack is a 2,238' horizontal producer, which will access reserves in the northern part of DS18. The lateral will be completed with a 3-1/4"x 2-7/8" L-80 liner which will be cemented and perforated. .- The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack is attached for reference. r M, � / �i�e� "fres a a+..

I've attached a snapshot of the production for the past couple years. Basically, each spike you see lasts for 4-5 days and occurs every couple months following a shut-in period to rebuild localized reservoir pressure. While the peaks are equivalent to great production,the average total production over a year is uncompetitive. In each event the well is produced until production drops off. Please let me know if this answers your question, and if you need anymore information.

In reviewing production information for this well I notice that when the well is on production it produces in the neighborhood of 350-400 BOPD on a producing day basis,which is a higher daily rate than a several L2 pad wells that are in continuous production, and the GOR and water cut is comparable to other wells. Which on the face of it doesn't sound like an uncompetitive well. I suspect what is happening, and why the well is considered uncompetitive, is that when the well is brought online you get great flush production for a day or two but then the well dies after a couple of more days and you have to wait a month or so for the well to recharge before it can be brought back on production. Is my assumption correct,or is there another process in play here that makes this well an uncompetitive producer? 1 • • Thanks, Dave Roby Sr. Reservoir Engineer Alaska Oil and Gas Conservation Commission (907) 793-1232 CONFIDENTIALITY NOTICE:This e-mail message,including any attachments,contains information from the Alaska Oil and Gas Conservation Commission(AOGCC),State of Alaska and is for the sole use of the intended recipient(s).It may contain confidential and/or privileged information.The unauthorized review,use or disclosure of such information may violate state or federal law.If you are an unintended recipient of this e-mail,please delete it,without first saving or forwarding it,and,so that the AOGCC is aware of the mistake in sending it to you,contact Dave Roby at(907)793-1232 or dave.roby@alaska.gov. 2 S Sundry Application Plug for Re-drill Wells Work Flow This process is used to identify wells that are suspended for a very short time prior to being re- drilled. Those wells that are not re-drilled immediately are identified every 6 months and assigned a current status of"Suspended." Step Task Responsibl 1 The initial reviewer will check to ensure that the "Plug for Redrill" box Geologist,, in the upper left corner of Form 10-403 is checked. 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). fi 2 If the "Abandon"box is checked in Box15 (Well Status after proposed Geologist work) the initial reviewer will cross out that erroneous entry and initial thea 1 it on both copies of the Form 10-403 (AOGCC's and operator's copies). 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. 7" r- • • o mCD o O > W 1 W 0 UJ E " 3' C 4 73 0NW v O P \., m ) ° N OA ?

PU, orient to 45R, RIH and bounced thru. I love Coiltrack!!! Continue RIH. Tagged up at 11900', and had overpull at PU. TF currently 90R, non scribed. Try to orient to 45R. TF stay the same and we twisted the coil. RIH, tag up at 11905'. Continue to PU and tag up. Now at 11908'. Nothing on the caliper log at this depth. Looks like we are pushing something down hole. DD reports that Reeves left the 3.25" nylon bottom nose off of their logging BHA in the hole. This may be it. Continue to work it in the hole. 20:25 - 20:45 0.33 CASE P RUNPRD Bottom is now hard at 11908'. Continue to PU and set down on the obstruction. Moving tool face with the orienter around clockwise each time we tag up. Orienter is torquing up the coil, but we get our TF change as we yo-yo pipe. Orient all the way around to the right, then back to the left in 30 deg steps. Hard tag up each time. Finally managed to beat our way thru it after hitting it for 20 minutes.

Mud Program: · RWO: 2% KCI and ~~ Biozan for milling. · CTD: Plo-Pro (8.6 [Jppg). Viscosified 6% KCI will be used for drilling if losses are total. Disposal: · All drilling and completion fluids and all other Class II wastes will go to Grind & Inject or Pad 3. · All Class I wastes will go to Pad 3 for disposal. Casing Program: · 1.760 ft of 3 3/16" slotted un-cemented liner. Well Control: · BOP diagrams are attached. . · Pipe rams, blind rams and the CT pack-off will be pressure tested to 400 psi and to 3500 psi. / · The annular preventer will be tested to 400 psi and 2500 psi. Directional · See attached directional plan. Max. planned hole angle is approx. -98 deg. · Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging · An MWD Gamma Ray will be run over the entire open hole section. A full suite of memory open hole logs will be run at TD consisting of GR/Resistivity/SoniclDensity/Neutron. -e -e Hazards · L2 is not an H2S Pad. Most wells on L2 Pad measure between 25 and 50 ppm H2S in produced fluids. ,;.~._......-- · Lost circulation risk is considered high. Drilling may be done with viscosified water if losses are total.

Mud Program: · RWO: 2% KCI and ~~liozan for milling. · CTD: PIo-Pro (8.6 (;lppg). Viscosified 6% KCI will be used for drilling if losses are total. Disposal: · All drilling and completion fluids and all other Class II wastes will go to Grind & Inject or Pad 3. · All Class I wastes will go to Pad 3 for disposal. Casing Program: // · 1567 ft of 3 3/16" slotted un-cemented liner. Well Control: · BOP diagrams are attached. // · Pipe rams, blind rams and the CT pack-off will be pressure tested to 400 psi and to 3500 psi. · The annular preventer will be tested to 400 psi and 2500 psi. Directional · See attached directional plan. Max. planned hole angle is approx. -98 deg. · Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging · An MWD Gamma Ray will be run over the entire open hole section. A full suite of memory open hole logs will be run at TD consisting of GR/Resistivity/Sonic/Density/Neutron. . . Hazards . L2 is not an H2S Pad. Most wells on L2 Pad measure between 25 and 50 ppm H2S in produced fluids. .- · Lost circulation risk is considered high. Drilling may be done with viscosified water if losses are total. Reservoir Pressure · Pore pressure is estimated to be 3195 psi at 8900'TVDss (6.9 ppg). / · Maximum surface pressure with gas (0.1 psi/ft) to surface is 2305 psi .

All depths are Measured Depths (MD) unless otherwise noted. All depths are Bit Depths unless otherwise noted. All Gamma Ray data (GRAX) presented is real time data. Well 15-19A was kicked off @ 8810' MD (8622' SSTVD) from the wellbore of Well 15-19. Well 15-19A was drilled to 11097' MD (8759' SSTVD). The TD was shifted to 11060' MD (8759' SSTVD) following a -37' depth adjustment after a tie-in. The interval from 11079' MD (8759' SSTVD) to 11096' MD (8759' was not logged due to sensor to bit offset. The KCI content in the mud was changed from 15000 mg/l to 34000 from 10724' MD (8730' SSTVD). The data presented here may not be final and will possibly be shifted to a PDC (Primary Depth Control) log later.
