There are several unperforated Z4 targets expected to increase oil rate and improve WC. Objective:Utilize CTU to surface deploy TCP guns to add new perfs and improve WC. Sundry Procedure (Approval Required to Proceed): Note: The well will be killed and monitored before making up the extended perfs guns. This is generally done during the drift/logging or plug set run. This will provide guidance as to whether the well will be killed by bullheading or circulating bottoms up throughout the job. If pressure is seen immediately after perforating, it will either be killed by bullheading while POOH or circulating bottoms up through the same port that opened to shear the firing head. Coil Tubing 1. MIRU Coiled Tubing Unit, spot ancillary equipment and PT. 2. Bullhead ~230 bbls of 8.4 ppg 1% KCl or equivalent down the tubing to the formation to kill well ahead of extended perforations and fluid pack well for logging. a. Wellbore volume = 10200’ X .0152 bpf = 160 bbls b. Freeze protect tubing as needed. 3. MU GR/CCL Logging tools and RIH. 4. Log up from ~11650’ MD to 11200’ MD stopping at ±11,350’ MD to paint flag. 5. POOH and confirm good data. Obtain corrected flag. 6. At surface, prepare for deployment of TCP guns. Assure excess fluids available if needed to keep hole full. 7. Confirm well is dead. Bleed any pressure off to returns tank. Kill well w/8.4 ppg 1% KCl or equivalent as needed. Maintain continuous hole fill taking returns to tank until lubricator connection is reestablished. 8. Pickup safety joint and TIW valve and space out before MU guns. Review well control steps with crew prior to breaking lubricator connection and commencing makeup of TCP gun string. Once the safety joint and TIW valve have been spaced out, keep the safety joint/TIW valve readily accessible near the working platform for quick deployment if necessary. * -00 DLB CTU Extended Perf W-45 PTD:207-127 9.

Currently we are only able to get a LOT of 9.7 to 9.9 ppg outside of the surface casing shoe. We have inspected the surface equipment and everything seems to check out. There are no anticipated faults at our shoe. We suspect it may be the TAM collar and are currently running in the hole with a TAM shifting tool to attempt to re-shift the collar closed. If this fails we will pick up an RTTS and attempt to isolate any leaks in the casing/TAM collar. Finally, if no leaks are found, we attempt a cement squeeze on the shoe to isolate any loss zone. This is just a heads up on our operations. The cement job wouldn't be until tomorrow, so if you need anymore details I would be happy to give them to you.

However, since this is a producer, we only need to test casing and tubing to 3500 psi. 1 would like to request that our BOP tests be changed from 4000 psi to 3500 psi on the Rams, and remain at 2500 psi on the Annular Preventer.

No wells will require subsurface shut-in during drilling operations. Reference the Anti-collision report in the directional plan for a full list of offset well paths. W-45 Permit to Drill Application Page 5 i ~- Well Control Surface hole will be drilled with a diverter. The intermediate and production hole sections will be drilled with well control equipment consisting of 5000 psi working pressure pipe rams(2), blind/shear rams, and annular preventer. This equipment is capable of handling maximum potential surface pressures. Based upon calculations below, BOP equipment will be tested to 4,000 psi. Due to anticipated surface pressures not exceeding 3,000psi it will not be necessary to have two sets of pipe rams installed at all times.

After drilling past the larger rocks and wood sections, the flow paddle will be put back in the flow line. • To mitigate any risk involved with no flow paddle, the following steps will be taken while the flow paddle is removed from the flow line. Ensure PVT alarms are used and the pit levels are accurately monitored for any pit gain. Visually look down the riser during connections to ensure the well is not flowing. Disposal • No annular disposal in this well. • Cuttings Handling: Cuttings generated from drilling operations will be hauled to grind and inject at DS-04. • Fluid Handling: Haul all drilling and completion fluids and other Class II wastes to DS-04 for disposal. Haul all Class I wastes to Pad 3 for disposal. W-45 Permit to Drill Application Page 6 Drilling Hazards and Contingencies POST THIS NOTICE IN THE DOGHOUSE I. Well Control /Reservoir Pressures: The Schrader Bluff sands are expected to be pressured at 8.7 ppg EMW. There is no Kuparuk sand expected in this well, but if present pressures would range from 9.8 - 10.0 ppg EMW. The Ivishak is expected to be pressured at 7.9 -8.1 ppg EMW. II. Hydrates and Shallow gas: Gas Hydrates are expected at W-pad near the base of the permafrost. Setting casing through the SV1 should keep hydrate exposure from extending past the surface hole. Recommended practices and precautions for drilling hydrates should be followed in the surface hole. Occasionally hydrates are encountered below the SV1. III. Lost Circulation /Breathing: Lost circulation is considered low to moderate at the faults in the intermediate section, and the LCM tree for non-pay zone sections should be followed if losses occur. Lost circulation is considered moderate to high in the production hole sections. The LCM tree for solid liners should be followed if losses occur. The Shublik phenomenon could occur on this well, however all lessons learned have been applied within the plan to mitigate this potential. Follow the RP guidelines for dealing with it if it occurs. IV. Kick Tolerance /Integrity Testing: Intermediate Section Kick Tolerance and Integrity Testing • Integrity Test - 8-3/4" hole: LOT 20' - 50' from 9 5/8" shoe • Kick Tolerance: 139.0 bbl KT with a 11.2 ppg mud and a 11.8 ppg LOT Production Section Kick Tolerance and Integrity Testing • Integrity Test - 6-'/8" hole: FIT 20' - 50' from 7" shoe • Kick Tolerance: Calculated an Infinite KT with a 8.5 ppg mud with 10.5 ppg FIT V. Stuck Pipe There could be slight differential sticking across the open hole while running the 7" casing. Keep the casing moving as much as possible and follow the centralizer program to help with standoff. VI. Hydrogen Sulfide W Pad is not designated as an H2S site, however Standard Operating Procedures for HzS precautions should be followed at all times. H2S levels across the pad are typically in the 10 to 30 ppm range based on the latest samples taken. VII. Faults There is a low to moderate risk of losses incurred when crossing faults #1 and #2 in the intermediate section. There is a moderate to high risk of losses incurred when crossing faults #3 and #4 in the production section. Formation Where Encounter Fault MD Intersect TVDSS Intersect Est.

RE: W-42 Tom- Sorry to get back to you so late, but I've been swamped with catching up since getting back from vacation. I'm assuming you are referring to the Permit to Drill for W-45, not W-42. I have answered your questions below. I also wanted to let you know that we have modified the directional profile since I sent in the permit. Our latest plan has changed through the intermediate section with less directional difficulty and tortuousity. All of our targets in the production section are essentially unchanged. Please let me know if you have any other questions.

I need some clarification on the cement calculations and yields. --is your surface lead deepcrete or litecrete? Deepcrete --using the 1.16 yield for surtace tail and 85 bbls volume, I calculate 411 sx. That is correct. I missed that in the original permit. --the intermediate lead yield is given as 1.53, but that seems low for 12.5 ppg . Slb provided me with the incorrect yield. It will actually be a yield of 2.24 cuft/sk, which will actually yield 436 sks for the 174 bbl job. -the liner cement weight is given as 15.8, but the yield is 1.53 which seems low. Again, the yield for the liner job should be 1.17 cuft/sk. This will yield a job quantity of 444 sks for the 92.6 bbl job. 2. Although Kuparuk is not expected at this location, what is the MASP for the intermediate hole if it is encountered?
