BY ORDER OF COMMISSIONER THE COMMISSION ORIGINAL af (,1 Date: SUBMIT IN DUPLICATE ) ) ConocoPhillips Alaska, Inc. Alpine Well CD2-37 PTD 202-211 Sundry Notice 10-403 Request From: Guy Schwartz (CPAI) Date: 2-24-04 To: Tom Maunder Subject: CD2-37 Fracture Stimulation Overview: CD2-37 was completed 11/28/2002 as an openhole horizontal well and has produced briefly at rates (-400 SOPD) to low to remain online. The productivity of CD2-37 is too low to enable continuous production into the common line gathering system. Approximately 3.1 MM barrels (gross) of reserves are at risk if the well remains shut-in. It is therefore requested that CD2-37 be fracture stimulated to capture these reserves at risk. Assumptions: * CD2-37 will not be returned to production without rate enhancement. This will result in loss of pattern reserves in excess of 3.1 MM barrels (gross) * Injectors have been drilled to provide pattern pressure support to CD2-37. That said, given the changing depositional environment on the southern periphery, it must be recognized that continuity across pattern distances is not assured. We know that CD2-37 was found to be pressure depleted when drilled which confirms some continuity to the Alpine sands being produced in the core area of the field. * This is the first horizontal fracture stimulation on an Alpine producer. There is some degree of uncertainty as to the outcome and ultimate success of the stimulation. The preliminary fracture stimulation design calls for placing 310,000 Ibs of 16/20 into the formation. A detailed stimulation procedure is currently being developed for this well. Please call me if you have any questions or comments on this procedure. ) ) CD2-37 Fracture Stimulation Procedure FRACTURE TREATMENT: OBJECTIVE: Create a co-linear frac in the open hole section of the Alpine C sand. 1. MIRU clean insulated frac tanks. Load tanks with diesel (approximately 2500 bbls are required for the treatment) 2. Rig up Dowell equipment and stab Tree Saver 3. Pressure test surface lines to 9500 psi 4. Pump the 100 bbl Breakdown with Dowell's YFGOIII fluid. Bring pumps up to maximum rate ASAP. 5. Pump the following schedule at 30 BPM with a maximum pressure of 9000 psi, add breaker as per lab results. . 285 bbls YFGOIII Pad 260 bbls YFGOIII wi 2 ppa 16/20 Carbolite 560 bbls YFGOIII wi 4 ppa 16/20 Carbolite 1050 bbls YFGOIII wi 6 ppa 16/20 Carbolite 150 bbls Slick Diesel flush . . . . 6. Monitor the surface pressure fall-off at the end of the job for 30 min if the well does not screen out. 7. Rig down equipment, move off location 8.

CD2-38 will be the closest well to CD2-37, 11.0' at 300' MD. Accounting for survey tool inaccuracies, the ellipse separation between these wells will be 5.8' at 300' 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. . ~nnular PumDina Ooerations: Incidental fluids developed from drilling operations on well CD2-37 will be injected into a permitted annulus on CD2 pad or the class 2 disposal well on CD1 pad. Incidental fluids to include oil based mud using mineral oil as the base fluid. The CD2-37 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 CD2-37 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 USDWs 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 = 2,991 psi = 1 ,081 psi Pore Pressure /0'--:>,"\ i'.' ) Therefore Differential = 2991 - 1 081 ~Si. 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: \Nt OD (ppf) Grade Range 9-5/8" 36 J-55 3 7" 26 L-80 3 Connection Type Collapse BTC.I / 2,020 psi J- BTC-Mod 5,410 psi 85% of Collapse 1,717 psi 4.599 Dsi / Burst 3,520 psi 7,240 psi 85% of Burst 2.992 psi / 6,154 psi J JIG..

Keep ~owline viscosity at :t: 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 wellbore 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. Calcium carbonate bridging material will be added to minimize formation damage. 0,1/ G I L ') Colville River Field CD2-37 Production Well Completion Plan - Î ! ¡ ! i - 16" Conductor to 114' Updated 10/09/02 ...1 4-112" Cameo BAL-O SSSV Nipple (3.812" ID) at 2000' TVD=2272' MD Isolation Sleeve with DB-6 No-Go Lock (3.812" OD) run in profile Dual 1/4" x 0.049" s/s control lines 9-518" 36 ppf J-55 BTC Surface Casing @ 3085' MD /2390' TVD cemented to surface WRDP-2 SSSV (2.125"ID) w/ DB-6 No-Go Lock (3.812" OD) - to be installed later !!..J Camço KBG-2 GLM (3.909" 10) at 3400 TVO for E Oummywith 1" BK-2 Latch PAcker Fluid mix: niesel in tUbinQ and Annulus -r- 'I ".at W'GA- A.4Ii» 12.6 ppf L-8Q IBT Mod.
