The A bore came on at marginal rates with minimal WC, and minimal gas. The well stayed around these production values until July-2011 when a slotted liner lateral was added to the 05-35A in an attempt to make it a more economical well to produce. The well had a few flush tests then settled out right back at the prior rates of 05-35A. the L1 lateral was drilled in very low net to gross sand, and the production trends agree with this. The rig will set a 45 KB Packer whipstock at 10,485' MD and drill a new B lateral. Final P&A of the 05-35A, 05-35AL1 and 05-35AL2 PB1 will be completed with the primary liner cement of . 05-35B. A MIT of the liner lap will be completed to 2,400 psi. If the liner lap test fails we will set and test a 45 KB liner top packer post rig and MIT to 2,400 psi. Rig Work: (Began on January 26, 2013) 1. MIRU and test BOPE to 250 psi low and 3,500 psi high. 2. Bull head kill the well with 1% 8.4 ppg KCI. 3. Set 4-Y2" TT flow through packer whipstock at -10,800' MD. (Below the new gas contact point). 4. Mill 3.80" window at 10,485' and 20' of rat hole. 6. Drill Build/Lateral: 4.25" OH, 2,750' (12 deg/100 planned) with resistivity to a TD of 13,235'. 7. Run 3-1/2" X 3-1/4" X 2-7/8" L-80 Cemented liner leaving TOL at -10,285' MD. 8. Pump primary cement leaving TOC at 10,285' MD, 31 bbls of 15.8 ppg liner cmt planned. 9. Perform liner cleanout with mill, motor and MCNL/GR/CCL log. 10.Test liner lap to 2,400 psi. 11. Perforate liner per asset instructions (-1,000'). 12. Freeze protect well to 2500' TVD 13.Set BPV, RDMO. Post-Rig Work: 1. Re-install wellhouse, flow line and pull BPV 2. Set liner top packer if needed with slickline & test to 2,400 psi 3. Set Gas lift valves 4. Test separator. David E.

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 v 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. Thanks, Steve D. file://F:\Daily_Document Record\Procedures_Instructions\FW INTENT PLUG for RE-DRI... 4/6/2012 Schwartz, Guy L (DOA) From: Roby, David S(DOA) Sent: Wednesday,January 02, 2013 3:05 PM To: Schwartz,Guy L(DOA) Subject Review of PBU 05-35A for abandonment contingency. Guy, I've looked at the subject well's production history in the event BPXA needs to abandon the existing well and lateral during the drilling of the 05-35AL2 well. 05-35A was never a good production well. Production peaked at a little over 300 bopd but has spent most of the past year plus producing less than 100 BOPD and is therefore not a viable production well. If conditions encountered while drilling the 1.2 lateral necessitate abandoning the existing wellbores I recommend we allow the operator to do so.

This well (DS 05-35A) is not going to be P &A'd so you will be dealing with a live well during the fishing operation. Are there any changes to the kickoff depth for the sidetrack once you recover the fish??

Since we have submitted the original PTD, the scope of rig operations have changed a bit. During some of the pre-rig work, service coil parted and left-4350'of 1.75" coil tubing in the hole. We have opted to fish this with the rig, then continue on with the planned sidetrack. During our fishing operation, we will equip Nordic 2 with 1.75"CT. Therefore, we will swap out both sets of the 2-3/8" Combi Rams with 1.75"Combi Rams. After we retrieve the fish, the plan will be to switch the rams back to 2-3/8" Combi Rams and swap our spool back to 2-3/8" Coiled Tubing. Attached is the BOPE schematic for the fishing operation. «Rig#2 circ and BOPE with 1.75 rams.xls» Let me know if you have any questions. 6/1/2011 05-35AL1 BOP Stack Page 2 of 2 Thanks, Mark Staudinger BP Exploration Alaska Operations Drilling Engineer Coiled Tubing Drilling (907)564-5733 (907)440-7403 cell 6/1/2011 `• .44 N I'll - 1 • \ ..7...: • w , ..:. 1 I_ o '•� T 1 cO k.:1+ EE l ISI III Da na,,, 2 -7A° - �m2 : _ ..„ ►, .

Well 05-35A was rotary sidetracked in September 2008 as a horizontal producer completed in Zone 1A with 1,320' of perforations. It required artificial lift to flow. Slickline drifted the well in December 2008 and tagged hydrates shallow at 1351' SLM. A Hot Oil Treatment successfully dissolved the hydrates but did not increase the well's production rates. In November 2010, slickline drifted the well again and the tools came out caked with paraffin, requiring a Hot Oil Treatment/ Brush & Flush before progressing. The well has continued to be fulltime producer on gas lift with steady low rates. Reason for Sidetrack: Well 05-35A is a low rate producer with no remaining wellwork options. Adding a lateral leg will increase production and reserves recovery, while maintaining offtake from the 05-35A parent well. The proposed sidetrack will provide additional offtake in a—60 acre drainage area in northwestern DS 05. The well is in sound mechanical condition. It passed an MIT-IA to 3000 psi (November 2010). The OA is an open annulus as per design to allow freeze protection after the cement behind the 7" longstring had set up. Tubing and liner are expected to be in good condition and no calliper exists as this well was just completed in September 2008. The lateral sidetrack, 05-35A L1, is scheduled to be drilled by Nordic 1 starting on February 25th, 2011 targeting Ivishak Zone 1A. The pre rig work includes milling an XN Nipple to 3.80" drifting for the 4'/2" retrievable whipstock and performing a MCNL logging run for gas identification. It is not planned to abandon the parent 05- 35A. The coiled tubing drilling rig Nordic 1 will then set a retrievable whipstock at 11,220' and to allow a kick off in Zone 1A. The window will be milled, the sidetrack will then drill 2160 ft of Zn 1A via 12 DLS and will be completed with 2-7/8" slotted liner dropped outside of window. Finally, the whipstock will be retrieved to allow for production from the parent well. The following describes the planned work. A schematic diagram of the proposed sidetrack is attached for reference. CTD Sidetrack Summary Pre-CT Rig Work: The pre CTD work is planned to begin February 5th, 2011. 1. W Check tubing hanger LDS. 2. W PPPOT-T to 5000 psi 3. C Mill XN Nipple at 9,508' md. -' 4. C Drift for 4%" retrievable whipstock. 5. C MCNL logging run. 6. V PT tree (MV,SV,WV) 7.

Pull BPV. 3. Install GLV. 4. RU test separator. Mud Program: • Well kill: 8.6 ppg seawater/brine. • Milling/drilling: 8.6 ppg Geo-VIS for milling window and drilling. Disposal: • All Class II drilling and completion fluids and all other Class II wastes will go to Grind & Inject at DS 4. • All Class I wastes will go to Pad 3 for disposal. Hole sizes: 33%" hole: 11,220' and— 13,380' and Casing Program: Slotted completion. • 2-7/8", L-80 6.5 lb/ft STL slotted liner 11,240' and— 13,380' and • Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3500 psi. ./ • The annular preventer will be tested to 250 psi and 2500 psi. Directional • See attached directional plan. Maximum planned hole angle is 93°, inclination at kick off point is 87°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property—35,000' md. • Distance to nearest well within pool—2021' from 02-02A BHL. Anti-Collision • 02-02 197' (ctr—ctr distance) Status: Plugged and Abandoned. • • 05-31A 193' (ctr—ctr distance) Status: Plugged and Abandoned. Logging • MWD directional, Gamma Ray and Resistivity logs will be run over all of the open hole section while drilling. • Cased hole GR/CCL/MCNL logs will be run pre-rig. / Hazards • DS 05 is not considered and H2S drill site. There are no producers on DS 05 or DS 02 with current H2S readings greater than 100 ppm. • The maximum recorded H2S level on DS 05 was 580 ppm on well 05-09A (June 1998), but the current reading is 10 ppm (March 2010). • Most recent H2S level on 05-35A is 30 ppm recorded on April 22th, 2010. This is the only H2S sample taken since the well was sidetracked in 2008. • The lost circulation risk in the 14-33A is considered to be low and no fault crossing is planned. Reservoir Pressure • The reservoir pressure is estimated to be 3,306 psi at 8,830 TVDss (7.2 ppg equivalent) based on average offset pressures. • Max expected surface pressure with gas (0.10 psi/ft)to surface is 2,423 psi.
