Overview: CD2-28: A hydraulic fracture treatment will be performed in the open hole horizontal section to establish communication vertically and longitudinally through the Alpine "C" sand. This will increase the wells production rate and reserves. A coil cleanout will only be performed should it be necessary post-frac. Procedure: 1. MIRU seven clean insulated frac tanks with a berm surrounding the tanks that holds the tank volume plus 10%. Load tanks with seawater from the injection system (approximately 2500 bbls are required for the treatment) 2. Rig up Dowell equipment and stab Tree Saver. (Test tree saver seals to expected pressure using warm diesel to assure seal integrity in tubing hanger). 3. Pressure test surface lines to 9500 psi 4. Pump the 200 bbl Breakdown with Dowell's YF125ST fluid system. Bring pumps up to maximum rate ASAP. 5. Pump the following schedule at 40 BPM with a maximum pressure of 7000 psi, add breaker as per lab results. Maintain 3000 psi on the IA during the treatment. ~\.\\s~~~\s\~ ~~.\ %'-\ ~O ~~\ 'bl_7h<1 ~{~ -() ì ~ · 300 bbls YF125ST Pad 240 bbls YF125ST wI 2 ppa 16/30 White Sand 480 bbls YF125ST wI 4 ppa 16/30 White Sand 1000 bbls YF125ST wI 7 ppa 16/30 White Sand Flush with linear YF125ST and freeze protect · · · · Total Sand: -310,000Ibs. 6.

"'"' ~\1 a-.. t) (j ;"'"'\ -,J 2i Enclosed please find a spreadsheet with a list of wells :fióm the Alpine field (ALP). 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 subsequently was filled with a corrosion inhibiter engineered to prevent water ftom entering the annular space.

CD2-29 will be the closest well to CD2-28, 9 a 300' MD. Accounting for survey tool inaccuracies, the ellipse separation between these wells will be . '" t 300' MD. prUllng 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 Pumplna Operations: Incidental fluids developed from drilling operations on well CD2-28 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 CD2-28 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 ceme~u above the top of the Alpine as per regulations. We request that CD2-28 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 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 Pore Pressure = 1,081 psi Therefore Differential = 2991-1081 =~../ 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 850/0 collapse and burst ratings listed in the following table: Wt Connection OD (ppf) Grade Range Type 9-5/8" 36 J-55 3 BTC / 7" 26 L-80 3 BTC-Mod / Collapse 2,020 psi 5,410 psi 85"0 of Collapse 1 ,717 psi 4.599 psi Burst 3,520 psi 7,240 psi 85"0 of Burst 2.992 psi 6,154 psi ,/ J ,J, ',",:,' ",~' ,,""" ,,' ,,, '" " ," ,~, '14 I ' , '4 '1 . ~ ';', ' .

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/ 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.

CD2-29 will be the closest well to CD2-28, 9.9' at 300' MD. Accounting for survey tool inaccuracies, the ellipse separation between these wells will be 2.8' at 300' MD. prillina 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 Pumpina ODerations: Incidental fluids developed from drilling operations on well C02-28 will be injected into a permitted annulus on C02 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 C02-28 surfacelintermediate 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 C02-28 be permitted for annular pumping of fluids occurring as a result of drilling operations, per regulation 20 MC 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)· (Surt. Shoe TVD) + 1,500 psi = (12.0 ppg) · (0.052) · (2390') + 1,500 psi = 2,991 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: \Nt Connection 85% of 85% of 00 (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 O Rû .r t~ g ,~ § .~ L .-:., h ,.' , , ,.
