It is intended to begin annular disposal operations on CD2-12 approximately December 24,2003. Please find attached form 10-403 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 1,4 mile radius, not already on file at AOGCC; CD2- 06, CD2-07 Further details regarding wells on CD2 pad within 1,4 mile radius should be on file at the AOGCC. The annular LOT (14.9 ppg) occurred at a lower equivalent mud weight than the casing shoe test (16.1 ppg). 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 information, please contact Vem Johnson at 265-6081, or Chip Alvord at 265-6120. ~~l~~ Vem Johnson Drilling Engineer cc: CD2-12 Well File Chip Alvord Nancy Lambert Sharon Allsup-Drake RECEIVED DEC 1 0 2003 Alaska Oil & Gas Cons. COrmMS$ion Anchorage ATO-1700 Anadarko ATO-1530 )~G1NAL ) ) Note to File CD2-12 (203-073...303-365) Colville River Unit (Alpine) ConocoPhillips Alaska, Inc Phillips has made application for annular disposal for the subject well. 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 220 bbls of cement was circulated to surface. The net cement remaining in the surface hole was 7% XS of the calculated hole volume. --On the initial leak off test, it was not possible to pump into the well at 16.1 ppg EMW. --The casing test and leak off pressure plot of CD2-12 essentially overlay each other. During the 10-minute observation period, the applied leak off pressure declined from 800 psi to 650 psi. --No problems. are reported drilling the intermediate hole or while running and cementing the 7" casing. The pipe was reciprocated during the cementing operation. There was no indication of lost circulation during the cementing operation. --On the injectivity test down 9-5/8" x 7" annulus, the pressure increases steadily to 610 psi where it broke. While pumping proceeded, the pressure varied between 550 and 580 psi. During the 1 O-minute observation period, the pressure declined from 560 to 380 psi. The EMW where the pressure broke was 14.9 ppg, with steady pump in at about 14.6 EMW. --CPA provided a listing of all surface casing shoes within % mile of CD2-12. The records of the wells within 1100' radius were examined and no problems were identified that would preclude granting CPA's request for CD2-12.

Designation of the well or wells to recei ve drilling wastes. 2. The depth to the base of freshwater aquifers and permafrost, if present. 3. A stratigraphic description of the interval exposed to the open annulus and other information sufficient to support a commission finding that the waste will be confined and will not come to the surface or contaminate freshwater. 4. A list of all publicly recorded wells within one- quarter mile and all publicly recorded water wells within one mile of the well to receive drilling waste. CD2-12 There are no USDW aquifers in the Colville River Unit. Base of Permafrost = 1552' TVD (RKB) The Schrader Bluff formation provides an upper barrier and marine shales and claystones of the Lower Cretaceous Torok Formation provide a lower barrier. Calculated water salinities of the Cretaceous and older stratigraphic sections range from 15000 to 18000 mg/I. (Ref. AOGCC Conservation Order No. 443, March 15, 1999) See attached map indicating wells within 1/4 mile. There are no water wells within 1 mile. 5. Identify the types and maximum volume of waste to Types of waste may be drilling mud, drilling cuttings, be disposed of and the estimated density of the waste reserve pit fluids, cement-contaminated drilling mud, slurry. completion fluids, diesel, formation fluids associated with the act of drilling a well, drill rig wash fluids, domestic waste water, any added water needed to facilitate pumping of drilling mud or drilling cuttings, and any other fluids associated with drilling a well. Densities range from diesel to 12#/gal. Maximum volume to be pumped is 35,000 bbls. 6. Description of any waste sought to be determined as Cement rinsate drilling waste under h (3) of this section 7.

Details that show the shoe of the outer casing is set below the base of any freshwater aquifer and permafrost, if present, and cemented with sufficient cement to provide zone isolation. 9. Details that show the inner and outer casing strings have sufficient strength in collapse and burst to withstand anticipated pressure of disposal operations. 10. Any additional data required by the Commission to NA confirm containment of drilling wastes. See attached cementing reports, LOT/FIT reports, and casing reports.

CD2-13 will be the closest well to CD2-12. Well separation is 9.3 ft at 300 ft MD. Accounting for survey uncertainty, the ellipse to ellipse separation is 3.2 ft at 300 ft 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 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 CD2-12 will be injected into a permitted annulus on CD2 pad or the class 2 disposal well on CD1 pad. The CD2-12 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. We request that CD2-12 be permitted for annular pumping of fluids occurring as a result of drilling operations, per regulation 20 AAC 25.080. 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 850/0 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 ) ') CD2-12 DRilliNG FLUID PROGRAM SPUD to Intermediate hole to 7" Production Hole 9-5/8"surface casing casing point - 8 Y2" Section - 6 1 18" point - 12 1A" Density 8.8 - 9.6 ppg 9.6 - 9.8 ppg 9.0-9.3 ppg PV 1 0 - 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 60/0 Suñace Hole: A standard high viscosity fresh water I gel spud mud is recommended for the surface interval. Keep flowline viscosity at ± 200 seclqt 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°k 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. ) ) CD2-12 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) MDrrVD(ft) (Ibs.

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. 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] D = [(14.5 x 0.052) - 0.1] x 2390 = 1563 psi OR ASP = FPP - (0.1 x D) = 3239 - (0.1 x 7157') = 2523 psi 3. Drilling below intermediate casing (7") ASP = FPP - (0.1 x D) = 3236 - (0.1 x 7152') = 2521 psi Colville River Field CD2-12 Injection Well Completion Plan 16" Conductor to 114' 4-1/2" Cameo DS Nipple (3.812') at 2000' TVD = 2185' MD 9-518" 36 ppf J-55 BTC Surface Casing @ 2660' MD 12390' TVD cemented to surface 4-1/2" 12.6 ppf L-80 IBT M tubing run with Jet Lube Run'n'Seal pipe dope Cameo KBG-2 GLM (3.909" DRIFT 10) wi dummy Packer Fluid mix: 9.2 ppg KCI Brine with 2000' TVD diesel eap Tubing suspended with diesel Completion .MQ IY.Q Tubing Hanger 32' 32' 4-1/2", 12.6#/ft, IBT-Mod Tubing Cameo DB6 nipple 22185' 2000' 4-1/2", 1206#/ft, 1ST-Mod Tubing Cameo KSG2- GLM (3.909" ID) 8200' 6922' 4-1/2", 12.6#/ft, 1ST-Mod Tubing (2) Baker 53 Packer wI millout extension 8300' 6984' 4-1/2", 12.6#/ft, 1ST-Mod Tubing (1) HES "XN" (3.725")-61° ine 8400' 7037' 4-1/2", 12.6#/ft, 1ST-Mod 10' pup joint WEG 8412' 7043' Baker 83 Packer WI milloul extension al +1- 8300' MD <200' TVD from lop of Alpine TOC @ +1- 8064' MD 16826' TVD (>707' MD above top Alpine) Top Alpine at 8771' MD 17151' TVD Well TD at 13439' MD ¡ 7152' TVD 7" 26 ppf L-80 STC Mod Production Casing @ 8839 I 7157' TVD @+I- 872 ) \ Alpine, CD2-12 Well Cementina Reauirements 9 5/8" Suñace Casine: run to 2660' MD I 2390' TVD Cement from 2660' MD to 2160' (500' of till) with Class G + Adds @ 15.8 PPG, and from 2160' to suñace with Arctic Set Lite 3.

The intended spud date for this well is April 30, 2003. It is intended that Doyon Rig 19 be used to drill the well. CD2-12 will be drilled to penetrate the Alpine reservoir horizontally. After setting 7" intermediate 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 production. Note that it is planned to drill the surface hole without a diverter. There have been 38 wells drilled on CD1 pad and 31 surface holes drilled on CD2 pad with no significant indication of gas or shallow gas hydrates. All of the wells on CD2 have surface casing shoes within a 2000' radius of the planned surface casing shoe of CD2-12. 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 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: -Form 10-401 APPLICATION FOR Permit to Drill per 20 ACC 25.005 (a). -Fee of $100 payable to the State of Alaska per 20 ACC 25.005 (c) (1). -A proposed drilling program, including a request for approval of annular pumping operations. -A drilling fluids program summary. -Proposed completion diagram. -Pressure information as required by 20 ACC 25.035 (d)(2). -CD2-12 Cementing Requirements. -Directional drilling / collision avoidance information as required by 20 ACC 25.050 (b). Information pertinent to this application that is presently on file at the AOGCC: -Diagrams of the BOP equipment, diverter equipment and choke manifold layout as required by 20 ACC 25.035 (a) and (b). -A description of the drilling fluids handling system.
