This document examines the pertinent information for the well and recommends approval of ConocoPhillips' request. --Some severe lost circulation (80 bph) was experienced while drilling surface hole. This is unusual at Alpine. Losses were cured prior to running and cementing the casing with no problems experienced during the cementing operation. --Surface casing was cemented to surface. No problems were reported. Approximately 250 bbls of cement was circulated to surface. The net cement remaining in the surface hole was 48% XS of the calculated hole volume. -- On the initial leak off test, the pressure slope rises smoothly after filling the system to 18.1 EMW. Minimal fluid was pumped in. The pressure declined during the observation period to about 16.0 EMW. The initial leak off indicates that the surface casing shoe is well cemented. --No problems are reported drilling the intermediate hole. The 7-5/8" casing was run and successfully cemented. Full returns were noted and the casing was reciprocated. --An injectivity test down 10-3/4" x 7-5/8" annulus was conducted. Pressure steadily increases until the break at 15.6 EMW. The pressure declined with additional pumping to 13.6 -13.8 EMW. During the observation period, the pressure declined to 12.8 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. --There are 17 wells within 1300' of CD2-404 with 6 wells within 525'. The surface shoe of CD2-15 is closest, about 250' distant. CD2-15 was recommended for annular disposal in 2001. CD2-21 is 280' distant. During pump in testing the final pressures were lower than seen on other wells. CPAI did not pursue AD on CD2-21. CD2-23 and CD2-11 lie closer to CD2-404 and do not exhibit similar fall-off pressures. All proximate wells have been examined and are in my database. There are no identified issues with any of the wells. Based on examination of the submitted information, I recommend approval of ConocoPhillips' request for the subject well. =:::~ Sr. Petroleum Engineer May 8, 2007 G:\common\tommaunder\ Well Information\By Subject\Annular Disposal\070508--CD2-404.doc ~ ConocoPhillips Alaska P.O.

It is intended to begin annular disposal operations on CD2-21 approximately August 30, 2005 or as soon as a permit is available.. Please find attached form 10-403AD and other pertinent information as follows: 1. Annular Disposal Transmittal Form 2. Pressure Calculations for Annular Disposal 3. Surface Casing Description 4. Surface Casing Cementing Report & Daily Drilling Report during cement job 5. Casing and Formation Test Integrity Report (LOT at surface casing shoe). 6. Intermediate Casing Description 7. Intermediate Casing Cementing Report & Daily Drilling Report during cement job 8. Formation LOT on 9-5/8" x 7" casing annulus 9. Plan View of Adjacent Wells 10. List of wells on CD2 pad and the lateral distance from the surface casing shoe. 11. Additional information regarding wells within ~ mile radius, not already on file at AOGCC: CD2-31 & CD2-18 Further details regarding wells on CD2 pad within ~ mile radius should be on file at the AOGCC. The initial annular LOT (12.9 ppg) and subsequent annular LOT (13.7 & 14.3 ppg 8/5/05) occurred at a lower equivalent mud weight than the casing shoe test (17.5 ppg LOT). Therefore we conclude that waste will not migrate above the confining zone provided we do not inject with sustained surface pressures that win cause pressures at the surface shoe to be in excess of the shoe FIT /LOT.

The exception to tagging is null if unusual circumstance (most likely lost circulation, but riot limited to that) are encountered while setting the plug(s). Using viscosified mud in between the plugs is acceptable and should preclude the cement from moving. Good luck with the operation. Tom Maunder, PE AOGCC Johnson, Vem wrote: Tom, As discussed this afternoon, we are preparing to plug back the. pilot hole portion of CD2-21 PB1. Our current plan is slightly different from the plan described in the permit to drill application. We currently plan to place three cement plugs vs. two. The first from TO (20172' MD) to 100' + above the top of the Nechelik sand, the second will be placed 100'+ below the base of the Alpine and 100' + above the top of the Alpine. There will be mud and a hi-vis pill between the first and second plug. A third plug will be set +/- 200 ft above and below the planned kick off depth at +/- 8500' MD. This plug will have mud and a hi-vis pill below it. This is the plug that will be tagged and used to kick off and drill the intermediate section to landing in the Alpine sands. As described in the permit to drill application, we do not plan to tag lower plug(s). Let me know if you have any questions or concerns.

ORiGiNAL Well Proximity Risks: Directional drilling I collision avoidance information as required by 20 ACC 25.050 (b) is provided in following attachments. CD2-23 and its associated plug-back CD2-23PB1 will be the closest well to CD2-21. Well separation is 16.9' @ 700' MD. Accounting for survey uncertainties, the ellipse-to-ellipse separation is 4.5' @ 700' MD. Drillina 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 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 Pumpina Operations: Incidental fluids developed from drilling operations on well CD2-21 will be injected into a permitted annulus on C02 pad or the class 2 disposal well on CD1 pad. The CD2-21 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 CD2-21 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 potablelindustrial 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. 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 ORIGINAL - ",-"/ CD2-21 DRILLING FLUID PROGRAM Density PV YP Funnel Viscosity Initial Gels 10 minute gels API Filtrate HPHT Fluid Loss at 160 PH KCL Oil /water ratio SPUD to 9-5/8"surface casing point - 12 %" 8.8 - 9.6 ppg 20 - 60 100 - 200 Intermediate hole to 7" casing point - 8 }2" Production Hole Section - 6 1/8" 9.6 - 9.8 ppg 10 - 25 15 - 25 8.1-8.8 ppg 10-15 25 -30 /' NC - 10 cc / 30 min 4-8 <18 4 - 12 cc/30 min (drilling) 1 0-1 5 12-20 NA 12-14 cc/30 min 9.0-9.5 6% Approx. 80/20 8.5-9.0 9.0 - 10.0 Surface Hole: A standard high viscosity fresh water / 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/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 well bore stability. Production Hole Section: The horizontal production interval will be drilled with a 80/20 oil/water ratio M-I Versa-Pro mineral oil based drill-in fluid. The base fluid will consist of high flash point (>200 F) mineral oil with 25% by weight calcium chloride as the internal phase.

Test BOP's to minimum 3500 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]0 Where: ASP = Anticipated Surface pressure in psi FG = Fracture gradient at the casing seat in Iblgal 0.052 = Conversion from Ib./gal to psilft 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 . Drilling below conductor casing (16") ASP = [(FG x 0.052) - 0.1] D = [(10.9 x 0.052) - 0.1] x 114 = 53 psi OR ASP = FPP - (0.1 x D) = 1081 - (0.1 x 2390) = 842 psi 2. Drilling below surface casing (9 5/8") ASP = [(FG x 0.052) - 0.1] 0 = [(14.5 x 0.052) - 0.1] x 2390 = 1563 psi OR ASP = FPP - (0.1 x D) = 3271 - (0.1 x 7228') = 2548 psi 3.

The intended spud date for this well is December 24, 2005. It is intended that Doyon Rig 19 drill the well. / The pilot hole well, CD2-21 PB1 will be drilled through the Alpine C sand and Nechelik sand at +/-78° inclination for logging and evaluation purposes. The well will be plugged o -.J~\Ç)S:. rJ.. back 500+ MD feet above the top of the Alpine formation. The well CD2-21 will then be Y drilled off the 2nd cement plug at approximately 8500' MD and landed in the Alpine sand horizontally. A string of 7" casing will then be run and cemented in place. The horizontal section will be drilled with oil based mud using mineral oil as the base fluid. CD2-21 will be completed as an AlC sand producer. 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 52 w_ells drilled on C02 pad wi~h no significant indication of gas or shallow gas hydrates. Please find attached the information required by 20 ACe 25.005 (a) and (c) for your review.
