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 :trom entering the annular space. As per previous agreement with the AOGCC, this letter and spreadsheet serves as notification that the treatments took place and meets the requirements of form 10-404, Report of Sundry Operations. Please call Jerry Dethlefs or M.J. Loveland at 907-659-7043, if you have any questions. Sincerely, ~~C Jerry Dethlefs ConocoPhillips Well Integrity Proj Supervisor Attachment . .

For your consideration: after you finish drilling the horizontal section, run a CBT, CET, or other CQL - the additional cement cure-time may improve the performance of the CQL. If the CQL still does not meet requirements, after injection starts (a week or more), you can run a water flow log. In consideration of the possible need for additional diagnostics, you could set the tubing so the tail is a nominal 150' above the top of the Alpine instead of the 85' you proposed. If you have questions, please call me at 793-1226 Thanks, Blair Wondzell Michael D Erwin wrote: Blair, Thanks for clarifying your position on the USIT yesterday afternoon during your meeting with Doug and Mike. As you can see, there were differing interpretations on the cement quality in our shop, and it helped to clarify it with you before we move ahead. It helped me to recall your pass~fail criteria for USIT interpretation as well, which should make this easier in the future. Since our drillers are highly concerned about our chances of successfully squeezing the formation top at this time, we are preparing to drill ahead. Plans are to drill the horizontal section and proceed to complete the well with tubing. Thus my concern is where to set the packer to be close to the formation, and yet have adequate surveillance room. I plan to set the packer approx. 200' FiD (at +/-8,150') above Alpine Top (8,349' 3iD) so the tubing tail is approx. 100' (at +/-8,250) above the Alpine top, which has been our normal completion. This will leave me +/-85' of working room above the Alpine to "water-flow log" soon after the well goes on injection to further evaluate cement isolation. I understand from Doug that you would accept a WF log on injection which shows no fluids are moving upwards behind the casing. This packer setting will; - provide the minimum 50' of inspection I believe you will want, - as well as allow us room for a potential CTU squeeze, - while keeping the packer and tubing close to the formation top to minimize casing exposure. Do you have any concerns about this proposed completion, as it's early enough to make adjustments? Thanks, Mike 265-1478 1 of 1 9/29/99 2:17 PM Alpine USIT Subject: Alpine USIT Date: Tue, 28 Sep 1999 10:49:27 -0900 From: "Michael D Erwin" <MERWIN~mail.aai.arco.com> To: blair wondzell~admin.state.ak.us Blair, As we discussed, below is the CD1-26 USIT file we discussed this am. The top of the Alpine, and therefore the top potential perf depth is 8,349' MD. Please call or email your thoughts on this cement job. As we discussed, if a squeeze is required to obtain formation isolation for this injection well we should get right on it while the rig is over the well.

The permit to drill does not exempt you from obtaining additional permits required bv law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. Annular disposal of drilling wastes will not be approved for this well until sufficient data is submitted to ensure that the requirements of 20 AAC 25.080 are met. Annular disposal of drilling waste will be contingent on obtaining a well cemented surface casing confirmed bv a valid Formation Integrits.' Test (FIT). Cementing records, FIT data. and any CQLs must be submitted to the Commission on form 10-403 prior to the start of disposal operations. Please note that an.,,' disposal of fluids generated from this drilling operation which are pumped down the surface/production casing annulus of a well approved for annular disposal on Drill Site CD 1 must comply with the requirements and limitations of 20 AAC 25.080. Approval of this permit to drill does not authorize disposal of drilling waste in a volume greater than 35.000 barrels through the annular space of a single well or to use that well for disposal purposes for a period longer than one ',,ear. The bloxvout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035: and the mechanical integrits.' (MI) of the injection wells must be demonstrated under 20 AAC 25.412 and 20 AAC 25.030(g)(3). Sufficient notice (approximately 24 hours) of the MI test before operation, and of the BOPE test performed before drilling below the surface casing shoe. must be given so that a representative of the Commission max' witness the tests. Notice mav be given bx' contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. Sin~ ~/' Robert N. Christenson, P. E.

Note: Well Proximity Risks: Directional drilling / collision avoidance information as required by 20 ACC 25.050 (b) is provided in following attachments. CD1-24 will be the closest well to CD1-26 (20.1' at 294' MD). Accounting for survey tool inaccuracies, the ellipse separation between these wells will be 18.4' at 339' MD. Drillinq 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. However, there are no faults progosed within 500 ft of the proposed target polygon. Good drilling practices will be followed to ensure that mechanically induced losses are kept to a minimum. 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 Pumpin.q Operations: Incidental fluids developed from drilling operations on well CD1-26 will be injected into the annulus of a permitted well. The CD1-26 surface/intermediate casing annulus will be filled with diesel after setting intermediate casing. 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 CD1-26 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 at the base of the Schrader Bluff Formation (C-30). 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) * (2400') + 1,500 psi = 2,998 psi Pore Pressure = 1,086 psi Therefore Differential = 2998 - 1086 = 1912 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 CD1-26 & CD1-26 PB1 DRILLING FLUID PROGRAM SPUD to Intermediate hole to 7" Production Hole 9-5/8"surface casing casing point- 8 ¼" Section - 6 1/8" point- 12 ¼" Density 8.8 - 9.6 ppg 9.6 - 9.8 ppg 9.2 ppg PV 10 - 25 12 -18 YP 20 - 60 15 - 25 35 - 45 Funnel Viscosity 100 - 200 Initial Gels 4 - 8 18 - 22 10 minute gels <18 23 - 27 APl Filtrate NC - 10 cc / 30 min 4 - 12 cc/30 min (drilling) HPHT Fluid Loss at 160 <10 cc/30 min PH 8.5 - 9.0 9.0 - 10.0 9.0 - 9.5 KCL 6 % 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 Iow drill solids (by diluting as required) will all be important in maintaining wellbore stability. Treat mud with fluid loss additives prior to coring. Production Hole Section: The horizontal production interval will be drilled with a M-I FIo-Pro drill-in fluid. The base fluid will consist of 6% KCI, with _+ 30PPB calcium carbonate bridging material to minimize formation damage. FIo-Vis Polymer and FIo-Trol starch will be used for viscosity and fluid loss control respectively.

The intended spud date for this well is September 10, 1999. It is intended that Doyon Rig 19 be used to drill the well. CD1-26 PB1 will be drilled through to the base of the Alpine Sand at an inclination of approximately 33©. This will allow evaluation of the reservoir interval. CD1-26 will then be plugged back and sidetracked to enable a horizontal penetration of the Alpine reservoir. After setting 7" intermediate casing the horizontal section will be drilled and the well completed as an open hole injector completion. At the end of the work program, the well will be closed in awaiting field start up. 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 · , 2. 3. 4. o 6. 7. 8. 9. 10. 11. Form 10-401 APPLICATION FOR Permit to Drill per 20 ACC 25.005 (a).
