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, RG2401 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 top of cement. The corrosion inhibitor sealant was pumped in a similar manner March 21St- 22" , 2007. The attached spreadsheet presents the well name, top of cement depth prior to filling, and volumes used on each conductor. Please call Jerry Dethlefs or M.J. Loveland at 907-659-7043, if you have any questions. Sincerely, on Arend ConocoPhillips Well Integrity Field Supervisor Attachment C~ ConocoPhillips Alaska tnc.

My guess {f didn't research it) is they lost a bunch of packer fluids to the reservoir when they replaced the DCR - ~`y~Fc,.~ ~1a\~le v~~ pro ~~~ pcc~~-~c~\ ~-~~ It also could be thermal -they inject seawater that starts at 60 degrees at CPf= 3... 1Ne have had larger fill ups, but mostly they are in the ~25 bbls range...

Is the volume reduction due to the fluids cooling after drilling? Is this what is normally seen on the wells? Tom NSK Well Integrity Proj wrote, On 4/18/2006 10:35 AM: Tam, Sorry l didn't cc you when f answered the same question for Jim. This was an initial MITIA - we did not pre load the welt. 43 bbls is a lot, but the welt had not been loaded since completion, Since Spaulding was out there for State SVS testing; we asked him if he'd witness the MITIA {even though it wasn't loaded and ready). Other wise the Inspectors would have had to make a special trip to catch it. T/110 was 20001450/350 since it has been online and warm. Let me know if you need more data.

Please check into the MIT you sent. Although it says 1 of 3 12/28/2005 3:05 PM Re: CD2-1 l: Approval to Commence Injection • • CD2-11, the PTD number is for CD2-02 and the packer TVD does not agree with the depths on the wellbore drawing provided in the Schlumberger log. Any info on what the disconnect was with the prior processing of this log? Strange that the "cement top" in the prior presentation just vanished like the tool had been pulled into the tubing tail. Hence my supposition that the tubing tally might be off. Look forward to your reply, Tom Maunder, PE AOGCC Hanson, Kelli L wrote, On 12/27/2005 2:08 PM: Mr. Maunder, CPAI requests approval to commence injection into CD2-11. The SCMT bond log was run on December 14th and indicates good bond up to the tubing tail at '12,734' MD {6,934' TVD SS) from the deepest depth reached of 13,346" MD {7107" D SS}. As you knave, the original log showed the cement top to be below the tubing tail, which was inconsistent with the cement job plan and execution. The log was reviewed by Schlumberger and reprocessed to correct a software deficiency that locked on an incorrect set of values. Schlumberger has assured us this problem is under roves#igation. The reprocessed log showing good cement up to the tubing tail is attached. The packer is located at 12,660' MD {6,903' TVD SS) @ 65 deg. The top of the Alpine C sand is located at 13,696' MD {7,154' TVD SS} @ 85 deg. The top ofi the Alpine A sand is located at 13,780' MD {7,160' TVD SS) @ 88 deg. The 7° casing shoe is located at 13,809' MD {7,161' TVD SS) @ 88 deg, PBTD is located a# 18,187' MD {7,145' TVD SS) @ 92 deg. The casing was run to 13,809' MD {7,161' ND SS) below the top of the Alpine C interval {tap at 13,696' MD; 7154' TVD SS} and cemented on September 2S, 2005. The cement job went well with full returns. Cement Job summary is noted below.

I have looked at the log, and you may be right, there is something inconsistent in the data we have. The estimated TOC from the Schlumberger SCMT is significantly lower than I expected. The cement job went well; no losses, plugs bumped, floats held, and nothing to indicate a large washout while drilling. Given the volume pumped and the success of the cementing operation, the TOC should have been well above the tubing tail. We plan to re-examine the log with Schlumberger to confirm that the original interpretation is correct. I will let you know when we finish checking our data. Vern Johnson 907-265-6081 -----Original Message----- From: Thomas Maunder [mailto:tom maunderc~admin.state.ak.us Sent: Monday, December 19, 2005 2:42 PM To: Johnson, Vern Subject: [Fwd: 1C-20 cement evaluation log] Vern, I was over to look at some bond logs on Friday with Tim. We looked at CD2-11. I was surprised to see that the packer and tailpipe were above the logged top of cement. This is unusual. Have you seen the log from CD2-11?? As I thought of it more, the way the bond signature "goes to railroad tracks" might indicate that there is a depth error on the tubing. The appearance of the "tracks" looks very similar to the other logs where only a short section is logged below the tubing tail and there is no transition in the presentation. Boom, good cement to no cement right now!! Would you have a look at the CD2-il bond log and let me know your assessment. Thanks, Tom Maunder, PE AOGCC -------- Original Message -------- Subject: 1C-20 cement evaluation log Date: Mon, 19 Dec 2005 14:29:29 -0900 From: Billingsley, Tim A Tim.A.Billingsley~~coz:ocophillips.cam> To: tom znaunderGadmi.n.state.ak.us Tom, The approved 1C-20 permit to drill states that we would be using the LWD sonic log to evaluate the cement bond on the 7-5/8" casing for 1C-20 proposed injector. The sonic tool was going to be on the production 1 of 2 12/28/2005 2:34 PM RE: [Fwd: 1C-20 cement evaluation log] hole drilling assembly. ~ • Unfortunately, the LWD Sonic log on Alpine well CD-2-11 did not prove accurate when compared to a more conventional SCMT log on the same well. So the LWD sonic log will not be run on 1C-20. We are currently running the 7-5/8" intermediate casing at 1C-20. ConocoPhillips proposes to run the SCMT memory log on drill pipe before drilling out the 7-5j8" shoe to obtain cement bond information on 1C-20. The float track will have 3 joints in it so the bottom of the logged interval in this proposal will be about 120' above the shoe. Logging before drilling out the shoe will allow us to drill ahead with the drill out assembly and not trip out to run the log. Also, if there is poor bond, remedial operations would be better conducted before exposing open hole. In addition, after drilling the production hole, there might be lost circulation occurring and it would not be as prudent to log the 7-5/8" for cement evaluation while sustaining significant losses in the well.. However, if the SCMT fails to obtain useable cement bond information before the 7-5/8" shoe is drilled out, we would still have the option of trying another log after the slotted liner is run.

This permit to drill does not exempt you from obtaining additional permits or approvals required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the. event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. Please provide at least twenty- four (24} hours notice for a representative of the Commission to witness any required test. Contact the Commission's petroleum field inspector at (907} 659- 3607 (pager). Sincerely, 7 Cathy P.

The intended spud date for this well is September 12, 2005. It is intended that Doyon Rig 19 be used to drill the well ' i It is planned to core +/- 60 ft of Kanik (K2/K3 sand) for evaluation. After coring, the well will be landed horizontally in the Alpine C formation, then 7" casing will be run and cemented in place. ~ The horizontal section will be drilled and completed as an open hole injector. At the end of the work program the well will be shut in awaiting surface connection. Note that it is planned to drill the surface hole without a diverter. There have been 41 wells ' drilled on CD1 pad and 58 wells drilled on CD2 pad with no significant indication of gas or shallow gas hydrates. CD2-11 was previously permitted (permit no.204-141) in August 04. The original permit was cancelled, because at the time it did not look like the well was with economic limits. It is also requested that the packer placement requirement be relaxed to place the completion packer 250 ft TVD above the Alpine formation. This will place the completion at a maximum inclination less than 65° and allow access to the completion with standard wireline tools for future intervention. 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 ACC 25.005 (c) (1). 3. A proposed drilling program 4.

ORIGINAL • • Well Proximity Risks: Directional drilling /collision avoidance information as required by 20 ACC 25.050 (b) is provided in following attachments. CD2-12 is the closest well. Well separation is 2.3' @ 424' MD. Drilling Area Risks: There are no high-risk events (e.g. over-pressures zones) anticipated. ~ Lost circulation: Faulting within the Alpine reservoir section is considered to be the most likely cause of lost circulation. Standard LCM material is expected to be effective in dealing with lost circulation. 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 CD2-11 will be injected into the class 2 disposal well on CD1 pad, or a permitted annulus on CD2. The CD2-11 surface/intermediate casing annulus will be flushed with 300 bbls of fresh water prior to freeze protecting with diesel to 1700' TVD. The only significant hydrocarbon zone is the Alpine reservoirs and there will be more than 500' of cement fill above the top of the Alpine as per regulations. Upon completion of CD2-11 form 10-403, Application for Sundry Operations -Annular Disposal, 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 base of the Schrader Bluff Formation (C-40). These 450-500' 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. 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°lo collapse and burst ratings listed in the following table: OD Wt (ppf) Grade Range Connection Type Collapse 85% of Collapse Burst 85% of 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 ORIGINAL • • CD2-11 DRILLING FLUID PROGRAM SPUD to 9-5/8"surtace casing Intermediate hole to 7" casing point - 8 3/," Production Hole Section - 6 1/8" Density 8.8 - 9.6 ppg 9.6 - 9.8 ppg 9.0-9.3 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 / 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 /gel spud mud is recommended for the surface interval. Keep flow line viscosity at ± 200 sec/gt 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 /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 dri{I solids (by diluting as required) will all be important in maintaining wellbore stability. Production Hole Section The horizontal production interval will be drilled with a M-1 Flo-Pro drill-in fluid. The base fluid will consist of 6% KCI, with t 30PP6 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.
