The well penetrated the Kuparuk reservoir approximately -90' high and LWD logs showed signs of gas in the reservoir. Plans are to plug back and sidetrack to a Kuparuk target approximately 1200' to the south west of the current penetration. Below is an outline of the proposed plug back and sidetrack operations. Also enclosed is a schematic of the existing wellbore and proposed plug-back. If you have any questions or require any additional information, please contact me at 564-4178. Scope' RiQ Operations: 1. RIH to TD at 15,603' MD with 5" DP cement stinger. Circulate and condition well for cementing operations. Spot a balanced 15.8 ppg cement P&A plug from TD to +/-14,950' MDl-450' above the Top Kuparuk Reservoir). Plug volume should be based upon an equivalent hole diameter of 10.4" throughout this section (70 bbls total). Pull above cement plug and circulate DP clean. Spot a 11.0' ppg heavy mud spacer from top of cement P&A plug at -14,950' MD to -12,050' MD. Pull DP up to 12,800' MD and circulate out any excess heavy mud spacer above this point. 3. Spot a 10.7 ppg Form-A-Plug pill (cross-linked polymer pill) from 12,800' to -12,600' MD to act as a base for the upcoming cement kick-off plug. Pull DP above top of plug and circulate any excess pill out of DP. Pull to shoe and wait on Form-A-Plug to set (-6 hrs). 4. RIH to -12,300' and wash down looking for top of plug. Once top of plug is verified, condition mud as required for spotting the cement kick-off plug. 5. Spot a 15.8 ppg cement kick-off plug from 12,600' to 12,200' MD (estimated depths). Plug volume should be based upon an equivalent hole diameter of 11.5" throughout this section (51 bbls total). Pull DP above plug and circulate DP clean. POOH. / 6. PU 9-7/8" drilling assembly and RIH. Dress top of cement as required. Planned kick-off point is at -12,300' MD, however will kick-off soon if plug allows. Kick-off and drill the 9-7/8" hole section as per directional plan to TD @ :f:14,940' MD (7205' TVD). POOH. 7. Run and cement the 7", 26# production casing as required to cover all significant hydrocarbon intervals (no significant hydrocarbons were seen in the Ugnu or West Sak intervals and therefore, plans are to bring cement -1200' above top Kuparuk formation only). Displace the 7" casing with seawater during cementing operations. Once cement has had adequate time to set, freeze protect the 7" x 10-3/4" annulus as required. 8. RU slick-line and run gauge ring / junk basket to PBTD. 9. Run a 4-1/2",12.6#, L-80 TC-II completion and space-out tubing tail -50' MD above top Kuparuk. S-114 Application for Sundry ') ) 10. RU slick-line. RIH with standing valve and set in 'XN' nipple below packer. Set packer and test the tubing to 4000 psi and annulus to 4000 psi for 30 minutes. Shear open RP valve in bottom GLM. 11. Nipple down the BOPE. Nipple up and test the tree to 5000 psi. 12. Freeze protect the well to -2400'. Secure the well. Rig down and move off. Post-Riq Work: 1. RU e-line - Run Cement Evaluation log. 2. Perforate the Kuparuk interval, using bottom most GLM to circulate guns down as required. 3. Pull RP shear valve from bottom GLM and install dummy valve.

Both 8-105 and 8-106 are located -15' from the S-114 conductor and both 8-104i and 8-201 are -30' from S-114. Each well requires wellhouse removal for the move in of Doyon 14. The wells will need to be shut-in at the surface and the SSSV if present (see Close Proximity SOP listed below for details). All surface flowlines and gas lift lines will be depressured to header pressure. Also, the swab valve on S-106 will need to be removed to allow safe move in operations. The tree on 8-106 extends slightly higher than some of the adjacent wells, and as is will not comfortably fit under the Doyon 14 substructure. Therefore, the swab valve will be removed and a flange (with a gauge) installed on the 8SV. Discuss the move at a pre-job safety meeting and designate a spotter to ensure there is no danger of a collision. All wells can be brought back on production / injection once the move is complete. ~ 8 Pad is not designated as an H2S drill site, however Standard Operating Procedures for H2S precautions should be followed at all times. Recent H28 data from the pad is as follows: Adjacent producers at Surface: S-105 less than 10 ppm S-106 less than 10 ppm Adjacent producers at TD: S-106 less than 10 ppm S-107 less than 10 ppm / The maximum level of H2S recently recorded on the pad was -60 ppm from S-40A. The maximum level ever recorded on the pad was -130 ppm from S-32 back in 3/2001. Both of these wells are Ivishak producers while the above wells and subject well are Kuparuk wells. '>-'"""''''''''''''''''''''''''''~'''''~~~~-",''''''~''''''''''''''''''''''',,,,,,",,'.'''>"''-W''''''''''"-'''''''"IW.'-~------ Job 2: Drill Surface Hole Hazards and Contingencies ~ No fault crossings are expected in the surface interval of S-114. ~ Drilling Close Approach: All wells pass BP Close Approach guidelines under Major Risk rules for this hole section, however there is one close approach well which limits allowable well path deviation to -4.4'. The well is 8-106, and is -14' well-to-well at 425' MD. Note tolerance lines and allowable deviation from the planned 8-114 well-path. Also, a single shot gyro will be required in the surface hole due to magnetic interference of the close offset wells. The single shots could be needed as deep as -1100' where we finally get adequate separation from adjacent wells. » Minimal hydrate gas has been encountered in the recent Aurora S-Pad development. In the few wells where hydrate gas was reported, it was encountered within a range between the 8V3 and SV1 sands. S- 113 encountered gas cut mud at the top SV2, which cut the mud from 9.7 to 8.7 ppg (after this single incident, no other gas cut mud was seen while drilling to TO below the SV1). The off-set well S-106, encountered gas cut mud (most severe was from 9.3 to 8.0 ppg) at several different depths while drilling within the lower SV sands. If encountered, hydrates will be minimized by treating the mud system with Driltreat (Lecithin). Additional measures include reduced flow rates and keeping the mud temperature cool «60 degrees if possible). Refer to Baroid mud recommendation. S-114 Permit to Drill 8/26/02 Page 6 ) ) Job 3: Install 10%" Surface CasinQ Hazards and Contingencies ~ It is critical that cement is circulated to surface for well integrity. 2250/0 excess cement through the permafrost zone (and 400/0 excess below the permafrost) is planned. As contingency, a port collar will be run in the casing at -1000' MD to allow circulating cement to surface if the single stage is unsuccessful. ,»»,,,,,,,,,,,,,*,,~,-,-,,-,~,,," Job 4: Drill Intermediate/Production Hole Hazards and Contingencies ~ Four fault crossings have been identified in this hole section. As planned, the well will encounter the first fault at -12,122' MD / 5170' TVD, within the Schrader 0 Sands. This fault looks to be very similar if not the same fault that was crossed without incident while drilling the Schrader in S-113. The second and third faults are expected within the Colville interval at -14,205' MD /5840' TVD and -14,927' MD / 6250' TVD. These faults have not been crossed in off-set drilling, however based upon similar faults cut in S- 106 and S-113, lost circulation is considered to be a minor risk with both crossings. The fourth and final fault is expected within the Kuparuk A Sand interval at -15,821' MD /7000' TVD, and is also expected to have a minor risk of encountering losses. Nevertheless, have LCM products on location to treat any losses encountered. There is also a potential to encounter several small faults in the section 400' to 1000' TVD above the Kuparuk. The well path crosses over a known fault in this area, however the seismic data in this area is poor and any smaller faults in the area cannot be distinguished. ~ The Top Kuparuk target polygon has been sized to avoid faults to the north-east and south-west of the well path. Therefore, consider the entire polygon as a hard-line and maintain directional control to hit within the 'Drillers Polygon'. ~ Minor cuttings gas and gas cut mud has been fairly typical within the Ugnu and Schrader intervals. There is a potential for these intervals to be over-pressured in some areas around S-Pad, however S-114 should penetrate this section within an isolated fault block to the west where pressures are expected to be normal. The recently completed S-113 well, drilled these intervals with a 9.4 to 9.5 ppg mud (south of proposed path), and in July of 2001, S-107 (off-set well to the north) drilled the Ugnu and Schrader intervals with 9.5 ppg mud and no signs of being underbalanced. Nevertheless monitor closely for any signs of overpressure. ~ Differential sticking will be a problem if the drill string is left stationary for an extended period of time across the long permeable sections of the Ugnu and Schrader Sands. Minimize the time the pipe is left stationary. ~ Hole cleaning at high ROP's will be marginal in this large hole. For adequate hole cleaning flow rates should be maintained in the 650+ gpm range and pipe RPM's maximized, particularly while drilling with higher ROP's through the Ugnu and Schrader intervals. » KICK TOLERANCE: Based upon the expected Kuparuk reservoir pressure of 9.8 ppg and a 10.1 ppg mud, a 12.1 ppg leak-off will provide just over 50 bbls of kick tolerance. Contact Anchorage personnel if LOT is less than 12.1 ppg. Based upon off-set drilling data on S-Pad, a minimum leak-off of 12.5 ppg is expected at the 10-3/4" shoe and will provide -63 bbls of kick tolerance. An absolute worst case kick tolerance for the 9-7/8" open hole section would be 32 bbls assuming a kick from the Kuparuk at -15,812' MD / 7071' TVD. This is a worst case scenario based on a 10.0 ppg pore pressure gradient at the Kuparuk A Sand, a fracture gradient of 12.0 ppg at the 10-3/4" shoe, gauge hole, and 1 0.0 ppg mud in the hole. » Drilling Close Approach: All wells pass BP Close Approach guidelines. The nearest close approach well in this section is V-200, which is -471' welHo-well at -9822' MD in S-114. ----_._-'._.__.~'_.".._.._- ,.........--...-..-- S-114 Permit to Drill 8/26/02 Page 7 ) ) Job 6: Install 7" Lonastrina Casina Hazards and Contingencies )- Differential sticking is a concern across the long Ugnu and Schrader intervals. Communicate individual responsibilities to all members of rig team and review connection and casing running practices to minimize the time the pipe is left stationary. )- At this location the Schrader interval is expected to be wet. Therefore, current plans are to cover only the Kuparuk interval with cement. If the Schrader interval does encounter hydrocarbons which require cement isolation, a light weight lead cement will be pumped to meet AOGCC requirements. ~ The well will be underbalanced after displacing the cement with Sea Water.
