Objective: Adperf in the K2A Sands. Procedure: Slickline: 1. Pull SSSV. 2. Drift for w/ 2” x 20’ Dummy Guns to deviation @ ~12,950’ MD. Coil – Extended Perforating 3. MU GR/CCL in 2.2” carrier. Drift to PBTD, paint flag at appropriate depth per WSS discretion. Notes: x Remote gas monitoring for H2S and LELs are required for Open Hole Deployment Operations x Due to the necessary open hole deployment of Extended Perforating jobs, 24-hour crew and WSS coverage is required. The well will be killed and monitored before making up the initial perf guns. This is generally done during the drift/logging 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. 4. After MU MHA and pull testing the CTC, tag-up on the CT stripper to ensure BHA cannot pull through the brass upon POOH with guns. 5. Bullhead 1.2x wellbore volume ~232 bbls 1% KCL/SW down tubing. Max tubing pressure 2500 psi. (This step can be performed any time prior to open-hole deployment of the perf guns. Timing of the well kill is at the discretion of the WSS.)

At surface, prepare for deployment of TCP guns. 7. Confirm well is dead. Bleed any pressure off to return tank. Kill well w/ KWF, 8.4 ppg 1% KCl or SW as needed. Maintain hole fill taking returns to tank until lubricator connection is re-established. Fluids man-watch must be performed while deploying perf guns to ensure the well remains killed and there is no excess flow. 8.*Perform drill by picking up safety joint with TIW valve and space out before MU guns. Review standing orders 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. e.At the beginning of each job, the crossover/safety joint must be physically MU to the perf guns one time to confirm the threads are compatible. 9.Break lubricator connection at QTS and begin makeup of TCP guns per schedule below. Constantly monitor fluid rates pumped in and fluid returns out of the well. Fluids man-watch must be performed while deploying perf guns to ensure the well remains killed and there is no excess flow.

Well names currently include a forward slash "I" followed by an obsolete bottom hole location designator. HAK would like to retain the well number as well as the "A, B, C...." sidetrack designations but remove the "/suffix". For example, "DUCK IS UNIT SDI 1-09A/L21" would become "DUCK IS UNIT SDI 1-09A". The attached spreadsheet includes original and new names for all Duck Island wells. While performing the review of Duck Island well names, HAK found a single well, "DUCK IS UNIT SDI 4-20/M35" (PTD# 1861730), that should also be modified to include an "A" label to reflect the fact that the well is a sidetrack from the original "DUCK IS UNIT SDI 4-20/134" (PTD # 1861500). The original wellbore, abandoned 10/13/1986, was sidetracked to a new bottom hole location completed on 9/9/1987. This well appears to be one of the first sidetracks performed at Endicott. While the bottom hole code was changed, no letter was added to reflect the sidetrack. "DUCK IS UNIT SDI 4-20A" is also included on the attached spreadsheet.

The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10 -404, Report of Sundry Operations.

The sidetrack, 3-33NJ-35, will exit..oot-efthe existing 7" liner from a whipstock at 12820' md. The existing perforations in 3-33/K-37 will be abandoned by liner cement from the 3-33NJ-35 liner (P&A sundry form already submitted). The following describes the planned sidetrack. A schematic diagram of the proposed sidetrack is attached for reference. Pre CTD Summary (phase 1) 1) Slickline -Drift tubing. Dummy GL Vs, Pressure test IA to 2500 psi. 2) CT - FCO with under reamer to ±12840', log caliper in 7" liner, mill XN nipple to 3.80" ID, drift for whipstock. CTD Sidetrack Summary (phase 2) 1) MIRV CTD rig. 2) Set 4 Y2"x7" CTD whipstock at 12820' md. 3) Mill window with 3.80" OD diamond speed mill. 4) Drill 3.75" openhole sidetrack to ~14905' TD with MWDæ' ray/resistivity. 5) Run 3 1/2" x 2 7/8" solid liner completion and cement w· 28 Is of 15.8 ppg class G cement. ../ Bottom ofliner at TD, top ofliner at ~ 12430' md. WO. ressure test liner and lap to 2000 psi. Run liner top packer if needed. P&A of 3-33/K-37 is complete. 6) Perforate 3-33NJ-35 liner. 7) RDMO. Mud Program: · Phase ~: ~pg brine · Phase 2&!ppg used Flo Pro or biozan for milling, new Flo Pro for drilling. Disposal: · All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. · All Class I wastes will go to Pad 3 for disposal. Casing Program: · 3 1/2" x 27/8" 13Cr solid cemented liner completion from 12430' to TD at 14905'. The 3 1/2" will run from 12430' to 12880' and the 27/8" will run from 12880' to TD at 14905'. The liner cement volume is planned to be ~28 bbls of 15.8 ppg class G. Well Control: · BOP diagram is 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 109 deg. · Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging · MWD directional and Gamma Ray will be run over all of the open hole section. · MWD Resistivity is planned. . e Hazards ./ · Endicott row 3 has H2S readings over 100 ppm and ij..designated as an H2S pad. Maximum recorded IDS on the pad was 2000 ppm from 3-43/P-36. The last 3-33/K-37 H2S level was 80 ppm on 7/14/97. All IDS monitoring equipment will be operational. · Lost circulation has not been a problem in previous Endicott drilling. The 3-33A sidetrack is planned to cross one known fault and may drill thru a depleted low reservoir pressure interval. Lost circulation risk is considered "low", but LCM material will be on location as a contingency. Reservoir Pressure · Reservoir pressure is estimated to be 4446 psi7at -9913'ss (8.6 ppg EMW). Max. surface pressure with gas (0.10 psi/ft) to surface is 3455 psi. Distance to Endicott Unit boundary line · 3-33A/J-35 is 2740' from the Endicott unit boundary line at TD of 14905' md. Distance to nearest well within pool · 4-38/K-34 is 478'md away at 14435' in the 3-33A/J-35 directional plan. This close approach passes the BP major risk guideline.

All Resistivity and Gamma Ray data presented is real time data. Baker Hughes INTEQ utilized CoilTrak / USMPR downhole tools and Advantage surface system. (5) Tools run in the string included Casing Coil Locator, Electrical Disconnect and Circulating sub, a Drilling Performance sub, (inner and outer downhole pressure, downhole weight on bit, downhole temperature), a Gamma and Directional Sub, and a Hydraulic Orienting Sub with near bit Inclination sensor. (6) The data presentted here is final and has been depth shifted to a PDC (Primary Depth Control) logged by SWS on March 11, 2004. (7) The sidetrack was drilled from milled window in 7 inch liner. Top of window. 12828 ft MD (9971.9 ft SSTVD) Bottom of window. 12834 ft MD (9976.4 ft SSTVD) (8) Plugback wellbores were drilled off this borehole at 12922' MD from MWD Runs 4 through Run 10. (9) The interval from 14513' MD (10076.6' SSTVD) to 14540' MD (10086.6' SSTVD) was not logged due to sensor to bit offset. (10) Tied in to 3-33/K-37 at 12752' MD.
