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, 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 frac will consist of pumping _+200,000 pounds 16/20 Carbo-lite proppant, resulting in a 100 foot propped length with an average prop concentration of _+ 4 Ib/ft2. The procedure includes the following major steps: · S:.~:1::.06:': :i :."i' ::.:,:: i :~;:.:..' :. i:i: ::'. :::::: 5~M0031' :i:'~':'~:.iCTU:.hOt:: °i]lXyl. ene :wash.'.perfs. it::Ub:i'n:g~.~'~ :.; .:i: :i:. :: i:~....::. ;...;.' ..:.: :.:: :'.' :~: ::!i:. ~:.. · '~: :: :. i..:: .:.::.: :~.i. ~; ::.' .!i:::.: ;:.'..i::i ??:::;:..: !::'i :..:: :.:~ :. i :,...::; ::i,:: ::::~ ~,."!~i~f~'~:,f:rab p:t~pi'(LONGi;:C::OIL)':'::::: ::':. ::'/: :: :.::::'.:.: ':: :.i.i. ;.

CTU hot oil/xylene wash perfs tubing for frac prep verify all perfs accessible. 2. Set DGLVs in sta's 1,2&3. 3. Load annulus, pressure test IA to 3500 psi. Fracture Treatment 2) 3) Water requirements, heat water to - 100 F. A total of -2000 bbls filtered KCL water are required (excluding tank bottoms). RU the treesaver/isolation tool for 4 Y2 "- 12.6 #/ft. tubing (see attached schematic), Set pop-off at 8500 psi. PT backside and maintain 3500 psi throughout treatment (set IA pop-off at 4000 psi). Pressure test lines to 10000 psi. Set pump trips afterwards to 7500 psi. It is recommended that 5 pumps be on location. The maximum allowable surface treating pred'~''~ ~is 9200 psig. The well should treat ~' ,300 psig, allowing for 3500 psig of excess treating pressure. If the data frac indicates that the well cannot be treated below 8000 psig, then consult with town or onsite engineer before raising pump trips to max 9000 psig. 4) Pump Data Frac/SD per attached schedule; initial rate will be 5 bpm while displacing wellbore fluid, after spotting Data Frac fluid a few feet above top perf increase rate design for data frac. Shut down, monitor for closure time, calculate efficiency and re-design frac schedule as necessary (Pad size, fluid loss additive, Shut down for ISIP, strap tanks, calibrate flow meters and calculate excess perforation pressure, etc). Re-establish injection, when add rates are lined out start counting PAD. Pump the proppant schedule as detailed in the attached pump schedule. Flush with linear fluid containing 50% methanol for freeze protection 6) Bleed off excess annulus pressure. Rig down Service Company. Post Fracture Treatment (within 48 hours) 7) Perform CTU fill cleanout to PBTD. i) Perform clean-out slightly under-balanced (to minimize damage to frac & perfs) through portable clean-up separator. ii) Formation pressure will support equivalent ECD of 9.7ppg, if this limit is much be exceeded, use only gelled diesel, have lab verify that breaker loading is adequate to break polymer & mix water at 140° F. iii) It is important to slow down FCO rate when the top of the interval is reached. Excess proppant production can be caused by circulating too fast or kicking the well off too quickly. 8) Retrieve sidepocket gauge changeout DGLV's to LGLV's (deep design). 9) FLOWBACK: Drop 5bbls MeOH into IA, open production choke slowly to 100% and POP well with minimum lift gas (<500 MSCFD) to flow through portable clean-up separator (expect proppant to be flowed back while well is cleaning up). If WHT remains below 50 F, Pump 20 gal/hour MeOH down IA continuously (or 1 bbl at minimum rate possible every 2-hours). a) The objective is to have the frac flowed back within 5-10 days of pumping the frac b) Do not allow rates to exceed 20 bbl/hr for first 6-hours and gradually open choke during the remaining flowback period. The objective is to limit flowrate increases to a maximum of 750 BLPD in any 12 hour period. c) Once the flowback has initiated, do not shut-in the well until majority of proppant has been cleared from the tubing. d) Continue producing through clean-up separator until solids are down to trace (<0.2%) with the well at maximum drawdown (1200 GLR, wide-open choke). Obtain liquid sample and send to PBU lab. Return to GC2 and obtain well-test from S-pad separator as soon as possible (default NOC=0.865).

A CTU cleanout/HCL wash and adperf is proposed in well S-106 requiring long coil as soon as possible following move of rig Doyon 14 off of well S-107 (est. 8/3/01). The existing 34' perfs are excellent quality reservoir (-4000 BOPD influx during DPC-perforating), but we're damaged after the well was killed to run tubing. Based on experience with this well, and other offsets, Aurora wells are extremely sensitive to perforation plugging and require extremely high underbalance to obtain clean perf tunnels and avoid a fracture stimulation.

Faults: Minor faults are expected to be crossed beneath the Schrader Bluff and prior to reaching Kuparuk sand. All Aurora S-Pad wells drilled this year have contained oil at the top of the Ugnu. For this reason the 7" casing will be cemented to 500' above the Ugnu Ma. Gas kicks have been experienced in offset wells. Rig team and mud loggers must be advised of the critical requirement for early kick detection and well shut-in. Produced water injection may have over-pressured the Ugnu Cretaceous sand.

For this reason the 7" casing will be cemented to 500' above the Ugnu Ma sand (the uppermost significant hydrocarbon). The surface casing point was chosen just below the SVlsands. Freeze protection of the 10 %" x 7" annulus can be accomplished via a port collar installed on the 7" production casing (vs annular injection into permeable sands below the SV1 and above TOC). After freeze protecting the 7" x 10-3/4" casing annulus with dead crude via the TAM port collar, the hydrostatic pressure alone may be less than the formation pressure. Ensure a double-barrier at the surface on the annulus exists until the cement has set up for at least 12 hours. Expect trapped annulus pressure after pumping the dead crude.

Note that the casing must be landed on the mandrel hanger(not emergency slips) for this procedure to be valid w/out rigging up a false rotary table. For a landing tool w/LH Acme running threads, modify the landing joint to consist of a 24.5' lower section and a 10' top section w/a MBTC connection. When landed the top of the lower section will be above above the flowline but below the rotary slip bowl. This will allow cement returns(and any carried gravel) to pass directly to the flowline.

Longstring Cement program: We have modified our approach and will have 10186' length of 12 ppg lead "lite crete" cement followed by 1500' of 15.8 ppg tail cement. The displacement will be slowed to 4 BPM for the last 200 bbls in order to stay beneath the 13.5 ppg fracture gradient that we used in the simulation. We will attempt to place this cement in a single stage operation. 2. A Diverter will be utilized and the document has been edited to show this in both locations that this information is discussed. 3. Drill-pipe conveyed perforating will be conducted underbalanced by 1000 psi. A "Champ" packer and "fas-ill" valve will be run. This valve will close at the pre-set depth and an air cushion will be incorporated inside for the underbalance. The hole will be circulated clean prior to TOOH and the rig will maintain trip tables while TOOH to keep the hole full. 4. The surface casing setting depth has been changed to 5874' MD which is at the base of the SV1 sands. Cement volumes have been edited in the attached "Permit to Drill" supporting documentation. <<S-106 Permit to Drill .doc>> Thanks for your input ....

MWD RUNS 1-2 WERE DIRECTIONAL WITH DUAL GAMMA RAY (DGR) UTILIZING GEIGER-MUELLOR TUBE DETECTORS. 4. THE 9 5/8" CASING BECAME STUCK OFF BOTTOM AND ENDED UP BEING SET 1033' OFF BOTTOM. THE REMAINING OPEN HOLE WAS PLUGGED BACK TO THE CASING SHOE AT 5250' MD. S-106 PB1 DATA ARE PRESENTED ELSEWHERE. 5. MWD RUN 3 WAS DIRECTIONAL WITH DGR, ELECTROMAGNETIC WAVE RESISTIVITY PHASE-4 (EWRP4), ACOUSTIC CALIPER (ACAL), AND GEO-PILOT (ROTARY STEERABLE TOOL). 6. MWD RUNS 4 AND 5 WERE DIRECTIONAL WITH DGR, EWRP4, AND PWD. 7. DATA FROM 7119' MD TO 7200' MD (BIT DEPTHS) WERE LOST DUE TO MWD HCIM FAILURE ON MWD RUN 4.
