Overview: CD2-31: A hydraulic fracture treatment will be performed in the open hole horizontal section to establish communication vertically and longitudinally throughout the Alpine "An and "C" sands. A 4-1/2" liner is inside the open hole interval with perforated 5' pups spaced throughout the liner section. Bio-balls will be used to divert the sand stages and 3 RA tracers; Ir-192, Sc-46 , and Sb- 124 will be added to determine the effectiveness of diversion in an effort to create multiple fractures along the openhole interval. This treatment will increase the wells production rate and reserves. A coil clean out 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 stimulation equipment and stab Tree Saver. (Test tree saver seals to expected pressure using warm diesel to insure seal integrity in tubing hanger). 3. Pressure test surface lines to 9500 psi 4.

Vern, et al: Winton and I have discussed this matter and we conclude that no sundry notice will be required for this activity. You will be accomplishing the operations which you described in you application, although the plug back depth will be shallower due to the high dog-legs. This is a mechanical consideration and such operations have not traditionally required a sundry. Since there will now be some length between the plugs, attention must be given to the placement of the deep plug. Commission practice has been to waive witnessing the tag of a deep plug when it is set on bottom and no problems such as lost circulation are encountered. If the placement of the bottom plug is suspect, plans should be made to tag the TOC and verify its location. Performing the sidetrack will accomplish the tag of the second plug. You have approval to proceed with your operations as planned. Please call with any questions. Tom Maunder, PE AOGCC Johnson, Vern wrote: Tom/Winton, This weekend we changed the plan for drilling and plugback operations on CD2-31. The original plan was to drill 8-1/2" pilot hole through the Alpine for logging purposes, then plug back with a continuous plug from TD to ± 12100' MD. Then the well was to be sidetracked and landed horizontally in the Alpine reservoir. While drilling the pilot hole at ± 8300' MD, several unexpected high dogleg (up to 20°/100) sections were drilled. The decision was made to move the kick off point and plug back depth up hole to mitigate problems associated with the high dog leg. The revised plan was to place a plug on bottom to isolate the Alpine (planned TOC 12745' MD, 242' MD above the top Alpine C). A second plug was to be placed from ± 8500 to 8000' MD to be used as a kick off plug. There are no significant hydrocarbon bearing zones between the plugs. I spoke to Winton Saturday afternoon, we discussed the plan and he gave verbal approval to continue. He suggested that I follow up with an email today. Let me know if you have any questions, or if you need further paperwork on this issue.

Well Proximity Risks: Directional drilling / collision avoidance information as required by 20 ACC 25.050 (b) is provided in following attachments. CD2-32 will be the closest well to CD2-31. Well separation is 11.9' @ 500' MD. Accounting for survey uncertainties, the ellipse-to-ellipse separation is 2.4' @ 500' 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 PumpinQ Operations: Incidental fluids developed from drilling operations on well CD2-31 will be injected into a permitted annulus on C02 pad or the class 2 disposal well on CD1 pad. The CD2-31 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 CD2-31 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 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. 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 ORfGINAL /. .

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 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 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 flashpoint (>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.
