Those wells that are not re-drilled immediately are identified every 6 months and assigned a current status of"Suspended." Step Task Responsible 1 The initial reviewer will check to ensure that the "Plug for Redrill" box in the Patricia or Steve / upper left corner of Form 10-403 is checked. If the "Abandon" or "Suspend" V 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 Patricia or Steve work)the initial reviewer will cross out that erroneous entry and initial it on both copies of the Form 10-403 (AOGCC's and operator's copies). Instead, then check the "Suspended" box and initial that change. V Guy or Victoria 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 for Jenni Redrill" box, she 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, she will check the History tab Jenni 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, she 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 change Jenni 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 Jenni Geologists will check the "Well by Type Work Outstanding" user query in Patricia or Steve 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.

History and current status: F-19 was originally drilled but suspended in 1981 & completed in 1985. A RWO was performed in 1994. A successful rotary sidetrack was performed in 2009. Due to the 4-1/2" slotted liner completion the well has a very high GOR and very v limited, if any future on-time. Proposed plan: Sidetrack F-19A to the F-19B location using Nordic 1 Coiled Tubing Drilling rig on or around June 7, 2014. The F-19BC sidetrack will be a single string exit through the existing 4-1/2" slotted liner and kick off horizontally into the Sag River. The proposed sidetrack is a -3155' horizontal Sag River producer, which will access Sag River reserve targets in F pad. The lateral will be completed with a 3/12" 13Cr solid by 2-7/8" 13Cr solid/slotted liner. This Sundry covers plugging the existing F-19A slotted liner via a liner top packer set post rig with slick line (alternate plug placement per 20 AAC 25.112(i)) in conjunction with using swab cups & KB packer element inside run on the completion liner inside the expandable liner & relying on an expandable liner with swellable rubber for parent isolation. • 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. Pre-Rig Work (scheduled to begin March 15th, 2014) 1. S Pull PXN plug at 11,634'. Drift for whipstock. Caliper well. Mill 4-1/2" XN nipple at 11,634' to 3.80". Set a 4-1/2"Whipstock (TOWS 2. E at 12,150' ELMD). 3. F Perform injection test &freeze protect well to 2,500' with diesel 4. V PT MV, SV, WV. 5. V Set BPV pre rig. 6. 0 Remove wellhouse and level pad. Rig Work (scheduled to begin June 7th, 2014) 1. MIRU and test BOPE 250 psi low and 3,500 psi high. (MASP 1,842 psi) 2. Pull BPV and Bull Head kill well. 3. Mill 3.80" window and 10' of rathole. 4. Drill lateral: 4.5" OH, 3,155' (15 & 12° DLS planned). 5 Run primary expandable liner from - 12,200' to - 12,400' using swellable rubber as primary isolation. Run secondary expandable liner(s) across faults/loss zones as needed 6. using swellable rubber as primary isolation. Run 2-7/8"13Cr solid/slotted x 3-1/2" 13Cr solid liner leaving TOL at 7. 11,620' MD. 8. Freeze protect well to 2,500' MD. 9. Set TWC; RDMO. Post-Rig Work: 1. Re-install wellhouse, flowline and pull TWC. 2. Install generic GLV design. SBHPS. 3. Set liner top packer with slickline*. *Approved alternate plug placement per 20 AAC 25.112(i) 4. ASRC flowback.

The plan is to exit the parent F-19 wellbore from the 9-5/8" casing at 8,750' MD with an 8-1/2" BHA. The 8-1/2' hole will be drilled to the Top of the Sag River where a 7" drilling liner will be run and cemented 150' back into the 9-5/8" casing. A USIT log will be run to determine the extent of corrosion in the 9-5/8" casing. The results of the USIT log will determine the depth of a scab liner top. If necessary, the scab liner will be tied back to surface. Cement will be brought no more than 100' from the surface casing shoe to allow for future sidetrack opportunities. The production hole will be drilled with a 6-1/8" BHA building to horizontal with 20 degree doglegs. The well will then run horizontally through the Sag River formation to TD at 14,023' MD. The liner will be a 4-1/2" slotted liner and the tubing will be 4-1/2" chrome, tied into the top of the production liner. Please reference Sundry number 307-353 for P&A.

If the lower set of pipe rams cannot be tested during the primary BOP test, that set of rams will be tested at the earliest opportunity during path-forward de-completion work, i.e., after the completion has been pulled from the well. Safety concerns and spacing limitations with the wellhead height and tubing spool preclude us from installing a spacer spool in the BOP stack. Disposal • No annular injection in this well. • Cuttings Handling: Cuttings generated from drilling operations will be hauled to grind and inject at DS- 04. Any metal cuttings will be sent to the North Slope Borough. • Fluid Handling: Haul all drilling and completion fluids and other Class II wastes to DS-04 for injection. Haul all Class I waste to Pad 3 for disposal. F-19A Permit to Drill Application Page 6 Drilling Hazards and Contingencies POST THIS NOTICE IN THE DOGHOUSE I. Well Control A. The Ivishak in this fault block is expected to be under-pressured at 6.6 ppg EMW. This pressure is estimated based on offset well pressures. 3500 psi test pressure is in accordance with the RP for Prudhoe production well casing tests. II. Lost Circulation/Breathing A. The F-19A RST will not cross any mapped faults in the target polygon. The proposed well is located in an area of generally E-W trending faults. Fault #1 is a short, N-S trending, ~20 ft, D to E fault located 250 ft west of the BHL. Fault #2 is a major NE-SW trending, 180 ft, D to N fault located 500 north of the planned well path. Fault #3 is a generally E-W trending, 10-20 ft, D to S fault located about 300 ft north of and generally parallel to the planned well path. Fault #4 is a generally E-W trending, 20-35 ft, D to S fault located about 300 ft south of and generally parallel to the planned well path. B. This well is located in an area considered to have "Moderate" potential for Lost Circulation, according to the WURD study. Many of the wells in the immediate area have drilled through faults without noting losses. The closest well with significant LC was the F-37, located approximately 1300 ft SW of the BHL, which lost 7580 BBL into the Shublik (near the intersection of two mapped faults). Based on the available data, the F-18A should have average potential for Lost Circulation. Details of losses in the surroundin area are noted below: Well T e Loss bbls MD TVDSS Zone X LOC Y LOC E-29 ri 1000 11161 8405 Above Sa -LCU 658565 5976996 F-34A ri 22 10920 8627 Sa River 652948 5979395 F-37 ri 7580 10780 8633 Shublik 648449 5978495 F-42 ri 54 11650 9111 Below BSAD 651163 5980512 J-24A coil 350 12475 8586 Sa River 646579 5976485 J-24A coil 550 12895 8604 Sa River 646921 5976263 J-24A coil 190 10938 8594 Shublik A 645288 5976197 III.

Significant directional work will be required in the production hole section. Hole cleaning and differential sticking tendency will be of concern. Watch for signs of tight hole and short trip /back ream as required to avoid stuck pipe. VI. Hydrogen Sulfide A. F-PAD is designated as an H2S site. F-19 H2S data is not available. H2S levels above the 100 ppm threshold have been recorded on this pad. VII. Faults A. The F-19A wellpath is not expected to intersect any mapped faults. See Section II on lost circulation for more details. VIII. Anti-Collision Issues A. Due to close approach concerns, one well will remain shut-in in order to drill F-19A. This is F-21 in the production holes, with the closest approach of 32.9 ctr-ctr at 12,598' MD.
