Some of these wells were found to have a void in the conductor by surface casing annulus. The voids that were greater than 3 feet were first filled with cement to a level of approx. 1.0 foot. The remaining volume of annular void respectively was coated with a corrosion inhibiter, RG240l engineered to prevent water from entering the annular space. As per previous agreement with the AOGCC, this letter and spreadsheet serves as notification that the treatments took place and meets the requirements of form 10-404, Report of Sundry Operations. The cement top-fill operation was completed on March 21st, 2007. Schlumberger Well Services mixed 15.7 ppg Arctic set I in a blender tub. The cement was pumped into the conductor bottom and cemented up via a hose run to the existing tOf of cement. The corrosion inhibitor sealant was pumped in a similar manner March 21 st - 22ß , 2007. The attached spreadsheet presents the well name, top of cement depth prior to filling, and volumes used on each con~uctor. Please call Jerry Dethlefs or M.J. Loveland at 907-659-7043, if you have any questions. Sincerely, \]}# ~ Arend· ConocoPhillips Well Integrity Field Supervisor ~ ~GANNEO MAR 2 8 2007 Attaclunent . . ConocoPhillips Alaska Inc.

This document examines the pertinent information for the well and recommends approval of ConocoPhillips' request. --No unusual events were reported while drilling the surface hole of the well. --Surface casing was cemented to surface. Approximately 240 bbls of cement was circulated to surface. The net cement remaining in the surface hole was 10% XS of the calculated hole volume. The 5XS left in the hole is lower than previously seen, however the engineer indicated that the job went well and the nut-plug "tattletale" was circulated from the well. -..On the initial leak off test, it was not possible to pump into the well at 18.0 EMW. The pressure declined during the observation period to 15.9 EMW. The initial leak off indicates that the surface casing shoe is well cemented. --No problems are reported drilling the intermediate hole. The 7" casing was run and became stuck prior to cementing. The 7" was cemented without pipe movement approximately 200' off bottom. Some minor lost returns was experienced while cementing. --An injectivity test down 9...5/8" x 7" annulus was conducted. Pressure steadily increases until the break at 15.0 EMW. Steady pump in occurred at 13.5 EMW. During the observation period, the pressure declined to 12.4 EMW. The lower EMW of the pump in test indicates that the planned disposal should be conducted at EMWs below that of the shoe integrity. --CPA provided a listing of all surface casing shoes within % mile of CD2-27. There are a total of 10 wells within % mile of the surface shoe. The nearest well is C02-51 about 350' distant. CD2-51 was approved for AD in late October 2003. There are 4 other wells between 700' - 900' away with 2 of the wells having been approved for AD. The remaining wells are in excess of 1000' distant. An examination of the files did not reveal any problem that would preclude granting CPA's request for CD2-27. Based on examination of the submitted information, I recommend approval of ConocoPhillips' request for the subject well. f::::1~ Sr. Petroleum Engineer June 22, 2004 G:\common\tommaunder\ Well Information\By Subject\Annular Disposal\040622......CD2- , 27.doc ( ( ConocoPhillips Alaska, Inc.

It is intended to begin annular disposal operations on CD2-27 approximately June 23, 2004. Please find attached fonn 10-403AD and other pertinent infonnation as follows: 1. Annular Disposal Transmittal Fonn 2. Pressure Calculations for Annular Disposal 3. Surface Casing Description 4. Surface Casing Cementing Report & Daily Drilling Report during cement job 5. Casing and Fonnation Test Integrity Report (LOT at surface casing shoe). 6. Intennediate Casing Description 7. Intennediate Casing Cementing Report & Daily Drilling Report during cement job 8. Fonnation LOT on 9-5/8" x 7" casing annulus 9. Plan View of Adjacent Wells 10. List of wells on CDl pad and the lateral distance from the surface casing shoe. 11. Additional information regarding wells within y.¡ mile radius, not already on file at AOGCC; CD2-57 Further details regarding wells on CD2 pad within lj.¡ mile radius should be on file at the AOGCC. The initial annular LOT (15 ppg) and occurred at a lower equivalent mud weight than the casing shoe test (18 ppg LOT). Therefore we conclude that waste will not migrate above the confining zone provided we do not inject with sustained surface pressures that will cause pressures at the surface shoe to be in excess of the shoe FIT/LOT. If you have any questions or require further infonnation, please contact Vem Johnson at 265-6081, or Chip Alvord at 265-6120. ~~.

I concur that isolation is demonstrated by the log. You have approval to commence injection into the well. Please coordinate with the Inspectors to have a witnessed MIT when one of them is next out at Alpine. Tom Maunder I PE AOGCC Crabtree I C L wrote: Tom CPAI requests approval to commence injection into CD2-27. This well was out of necessity completed slightly different from the normal Alpine injector because the 7" casing was stuck above the normal location the casing shoe is set..... After concluding the pipe was stuck. The casing was cemented with the shoe at 12,461' MD in the Alpine D interval. Normally the 7" shoe would be just below the top of the Alpine C at 12,530' MD. The cement job went well although circulation was lost on the last 10 barrels of the displacement. Job notes follow: RU cement head & lines - Establish circulation - circulate @ 4 BPM @ 530 psi - condition mud - PJSM on cement job Cement 7" casing as follows - Pumped 5 bbls CW 100 - test lines to 3500 psi - pump 15 bbls CW100 @ 3.2 BPM @ 425 psi - Mix & pump 50 bbls Mud Push XL @ 12.5 ppg @ 4.7 BPM @ 480 psi Dropped bottom plug - Mixed & pumped 37 bbls Class G wi .20% D46, .25% D65, .40% D1671 & .02% B155 @ 15.8 ppg - 5.1 BPM @ 500 psi Dropped top plug wi 20 bbls water fl Dowell - switch over to rig pumps & displace wi 452 bbls 9.6 ppg LSND mud @ 5 BPM @ 260 to 760 psi - slowed pumps to 2.5BPM & bumped plug wi 1500 psi - CIP @ 1830 hrs. Lost returns on last 10 bbls of displacement Check floats - OK - RD cement lines & head - LD mouse hole Since some of the D interval shale was open to the production hole after cementing casing , we elected to run the tubing tail through the 7" casing shoe in case the D interval would present hole stability problems in the future. Because this was the plan1 we elected to run a USIT bond log before running the tubing. The log indicates good isolation was achieved with the primary cement job. The tubing and casing were MIT'd - OK after 10f2 12/12/20033:34 PM Re: Approval to commence injection in CD2-27 e running the tubing. e ~OS-\l) Cliff Crabtree Alpine Subsurface Development - ConocoPhillips Alaska, Inc.

The key isolation required is around the penetration into the Alpine. As I understand, the D is not reservoir rock which gives some sealing ability and then the shale overlies the D. Based on your log interpretation, the shoe is set into the D. Running the evaluation log will help you determine the way forward and there is a possibility of sufficient isolation already being achieved. The only comment I have with regard to the proposed Bonsai is filling the ECP with brine. Has that been done previously?? My concern would be the potential to burst the elements as thermal equilibrium is achieved. I don't know if this is a risk, but it should be considered. Good luck with the evaluation and forward plans. Please keep us advised of your progress.

If the bond log looks good, and it is clear that we have 7" casing isolated in the Alpine D, we would prefer to run our typical Alpine injector completion, but with extra tailpipe running into the Alpine C sand. The extra tailpipe would facilitate running coil tubing in the future. > > If the bond log does not show sufficient isolation, we plan to run a Bonsai type isolation completion. See the attached proposed completion schematic. We are still working on a few details, but this is pretty much what it will look like. We may drop the upper ECP. Current plan is to fill the lower ECP with brine, pump cement around, then fill the second ECP with cement and set the liner top packer. > > Let me know if you have any questions or comments. > > Regards > > Vern Johnson > ConocoPhillips > 907-265-6081 > > «Visio-Revised completion schematic CD2-272.pdf» > > ------------------------------------------------------------------------ > > > > Name: Visio-Revised completion schematic CD2-272.pdf Visio-Revised completion schematic CD2-272.pdf Type: Acrobat (application/pdt) Encoding: base64 Description: Visio-Revised completion schematic CD2-272.pdf I . ____ - .. ..._____ - .,__,__ . ._."'_..'._n.'.. .'. _._____.._ .. _..__. .,.'. .0. .__.,. ___. ....,_ __._ ,..._._..

CD2-28 will be the closest well to CD2-27. Well separation is 8.8 ft at 350 ft MD. Accounting for survey uncertainty, the ellipse-to-ellipse separation is 2.9 ft at 350 ft MD. Drillinq Area Risks: There are no high-risk events (e.g. over-pressures zones) anticipated. Lost circulation: Faulting within the Alpine reservoir section is considered the most likely cause of lost circulation. Standard LCM material has proved effective in dealing with lost circulation in previous development wells. Additional care and attention will be ,given to the higher potential of inducing a kick when drilling horizontally as opposed to vertically. Good drilling practices will be stressed to minimize the potential of taking swabbed kicks. Annular Pumping Operations: Incidental fluids developed from drilling operations on well CD2-27 will be injected into a permitted annulus on C02 pad or the class 2 disposal well on CD1 pad. The CD2-27 surface/intermediate casing annulus will be flushed with 300 bbls of fresh water prior to freeze protecting with diesel to 2000' TVD. The only significant hydrocarbon zone is the Alpine reservoir and there will be 500' of cement fill above the top of the Alpine as per regulations. Upon completion of cD2-27 form 10-403, Application for Sundry Operations, will be filed. Annular pumping of fluids occurring due to drilling operations, per regulation 20 AAC 25.080, could then begin once properly permitted. As stated above, any zones containing significant hydrocarbons will be isolated prior to initiating annular pumping. There will be no USDW's open below the shoe or potable/industrial water wells within one mile of the receiving zone. Reference the enclosed directional drilling plan for other formation markers in this well. Surface casing will be set near the below the base of the Schrader Bluff Formation (C-40). These 300-400' thick shales are part of the Colville' Group and are known to provide vertical barriers to fluid flow in other areas. The maximum volume of fluids to be pumped down the annulus of this well will not exceed 35,000 bbl without the specific permission of the AOGCC. Fluid densities will range from diesel to a maximum of 12.0 ppg for drilling fluid wastes. Using 12.0 ppg fluid and the rig's specified maximum pumping pressure of 1,500 psi for annular injection, the maximum pressure at the surface casing shoe is estimated by: Max Shoe Pressure = (12.0 ppg) * (0.052) * (Surf. Shoe TVD) + 1,500 psi = (12.0 ppg) * (0.052) * (2390') + 1,500 psi = 2,990 psi Pore Pressure = 1,081 psi Therefore Differential = 2991 - 1081 = 1910 psi. The internal casing pressure is conservative, since frictional losses while pumping have not been taken into consideration. The surface and intermediate casing strings exposed to the annular pumping operations have sufficient strength by using the 85% collapse and burst ratings listed in the following table: Wt Connection 85% of 85% of OD (ppf) Grade Range Type Collapse Collapse Burst Burst 9-5/8" 36 J-55 3 BTC 2,020 psi 1,717 psi 3,520 psi 2,992 psi 7" 26 L-80 3 BTC-Mod 5,410 psi 4,599 psi 7,240 psi 6,154 psi I; CD2-27 DRILLING FLUID PROGRAM ) ) SPUD to Intermediate hole to 7" Production Hole 9-5/8"su¡1ace casing casing point - 8 Y2" Section - 6 1 18" point - 1.2 14" Density 8.8 - 9.6 ppg 9.6 - 9.8 ppg 8.8-9.3 ppg PV 10 - 25 10 -15 YP 20 - 60 15 - 25 25 - 30 Funnel Viscosity 100 - 200 Initial Gels 4-8 10-15 10 minute gels <18 12 - 20 API Filtrate· NC - 10 cc I 30 min 4 - 12 cc/30 min (drilling) HPHT Fluid Loss at 160 12 - 14 cc/30 min PH 8.5-9.0 9.0 -10.0 9.0-9.5 KcL 6% Surface Hole: A standard high viscosity fresh water I gel spud mud is recommended for the surface interval. Keep flowline viscosity at ± 200 sec/qt while drilling and running casing. Reduce viscosity prior to cementing. Maintain mud weight < 9.6 ppg by use of solids control system and dilution where necessary. Intermediate Hole Section: Fresh water gel I polymer mud system. Ensure good hole cleaning by pumping regular sweeps and maximizing fluid annular velocity. There is potential for lost circulation, particularly after the Alpine is penetrated. Maintain mud weight at or below 9.8 ppg and be prepared to add loss circulation material. Good filter cake quality, hole cleaning and maintenance of low drill solids (by diluting as required) will all be important in maintaining wellbore stability. Production Hole Section : The horizontal production interval will be drilled with aM-I Flo-Pro drill-in fluid. The base fluid will consist of 6% KCI, with ± 30PPB calcium carbonate bridging material to minimize formation damage. Flo-Vis Polymer and Dual-Flo starch will be used for viscosity and fluid loss control respectively. (), ,'.""',:," ."''''''',.' .~ "~.,I' , .: ~"" , , .',:' \, ,.' ,I " ~ , $ , \.",. '\~ CD2-27 PRESSURE INFORMATION AND CASING DESIGN (per 20 ACC 25.005 ( c ) (3,4) and as required in 20 ACC 25.035 (d) (2)) The following presents data used for calculation of anticipated surface pressure (ASP) during drilling of this well : Csg Setting Fracture Pore Casing Size Depth Gradient pressure ASP Drilling (in) MDfTVD(ft) (Ibs. 1 gal) (psi) (psi) 16 114/114 10.9 52 53 95/8 3359 1 2390 14.5 1081 1563 7" 12524/7151 16.0 3236 2542 N/A 17802/7212 16.0 3263 N/A . NOTE: The Doyon 19 5000 psi BOP equipment is adequate. Test BOP's to 5000 psi. PROCEDURE FOR CALCULATING ANTICPATED SURFACE PRESSURE (ASP) ASP is determined as the lesser of 1) surface pressure at breakdown of the formation casing seat with a gas gradient to the surface, or 2) formation pore pressure at the next casing point less a gas gradient to the surface as follows: 1) ASP = [(FG x 0.052) - 0.1]D Where: ASP = Anticipated Surface pressure in psi FG = Fracture gradient at the casing seat in Ib/gal 0.052 = Conversion from Ib./gal to psi/ft 0.1 = Gas gradient in psi/ft D = true Vertical depth of casing seat in ft RKB OR 2) ASP = FPP - (0.1 x D) Where; FPP = Formation Pore Pressure at the next casing point ASP CALCULATIONS 1.

The intended spud date for this well is November 4, 2003. It is intended that Doyon Rig 19 be used to drill the well. CD2-27 will be drilled to penetrate the Alpine reservoir horizontally. After setting 7" i~ermediate casing, the horizontal section will be drilled and the well completed as an open hole injector. At the end of the work program, the well will be closed in awaiting completion of well work and facilities work that will allow the well to begin injection../ Note that it is planned to drill the surface hole without a diverter. There have been 38 wells drilled on CD1 pad and 40 surface holes drilled on CD2 pad with no significant indication of gas or shallow gas ~...' hydrates. All of the wells onCD2 have surface casing shoes within a 2000' radius of the planned surface casing shoe of CD2-27. It is also requested that the packer placement requirement be relaxed to place the completion packer 200ft TVD above the Alpine formation. This will place the completion at a maximum inclination less than 650 and allow access-to-the--completion-w1th-st-andard-wireli-ne-tools-fof-futur-e-i ntervention. Please find attached the information required by 20 ACC 25.005 (a) and (c) for your review. Pertinent information attached to this application includes the following: 1. Form 10-401 APPLICATION FOR Permit to Drill per 20 ACC 25.005 (a). 2. Fee of $100 payable to the State of Alaska per 20 ACe 25.005 (c) (1). 3.
