As previously reported, initial diagnostics passed, but the initial IA drawdown test showed minor pressure fluctuations so a 30-day monitor on MI was commenced to allow an extended drawdown. During the first half of the monitor,the IA pressure appeared stable. During the second half of the monitor,the IA pressure has risen to suggest TxIA communication,though temperature fluctuations were also present. CPAI plans to drawdown the IA pressure and extend the MI monitor for 30-days for confirmation and to gather data on the IA pressure build-up rate while on MI. The well would then be WAG'd to water for a 30-day monitor period to confirm integrity on water. If integrity on water is confirmed an AA will be submitted. If TxIA on gas was confirmed, then depending on the results of the monitor periods,the AA application could be for water-only injection or for continued MWAG service with 'maintenance bleeds'. Attached is a 90-day TIO plot. Please let us know if you disagree with this plan. Regards, Rachel Kautz/Travis Smith Well Integrity Supervisor,ConocoPhillips Alaska Inc.

Tyler Subject: Alpine injector CD2-18 (PTD#203-151) Update Attachments: CRU CD2-18 90-day TIO plot.docx Chris, Alpine injector CD2-18 (PTD#203-151) was previously reported for an anomalous IA pressure increase while on MI injection. DHD has completed diagnostics and obtained a passing MITIA and packoff tests. The drawdown test did show very minor pressure fluctuations, so CPAI intends to put the well on a 30-day MI monitor to confirm integrity. If pressures appear normal throughout the monitor, we intend to treat the well as a normal MWAG injector. However, if TxIA communication becomes evident during the monitor, a follow-up email with a plan forward will be sent. Attached is the 90-day TIO plot. Please let me know if you have any questions or disagree with this plan. Regards, Rachel Kautz/Travis Smith Well Integrity Supervisor, ConocoPhillips Alaska Inc.

Let me know if there is anything else I you need. ~~~-l5 \ f¡. Vern Johnson -----Original Message----- From: Thomas Maunder [mailto:tom_maunder@adrnin.state.ak.us] Sent: Tuesday, February 24, 2004 11:29 AM To: Johnson, Vern; Alvord, Chip Subject: CRU CD1-07 :-EB 2 ry )ilnJ Vern and Chip, Recently approval for annular disposal and to initiate water injection into the subject wellbore were given. As I was filing information I noted a mud log report in the file which I examined. After reading the report, I have a couple of questions. These comments are in particular for the surface hole. It is indicated that after TDing the surface hole at 3016' md that it proved not possible to enter the old hole during the trip and a new wellbore was drilled from about 1104' to 2660' where the old wellbore was reentered. Surface hole was ultimately TDed at 3051'. It appears that the surface casing was successfully run and cemented with the intersection point some 400' md above the shoe. Although the initial leak off test showed 2 slopes, I think it unlikely that given the md between the intersection and the shoe depth that there is any communication with the lost section. I don't believe that the analysis of your AD application would have changed, however I do believe that information regarding the loss of the hole section should have been included in your application. CPAI was fortunate to have intersected the old wellbore. If the intersection had not occurred, there would have been 2 penetrations fairly close to each other at the shoe depth and the ability to use the well for annular disposal would likely have been compromised. In the future if an unplanned/unfortunate event such as this should occur, then that information should be part of any application that you might submit. This event does result in one other "big" question. surface hole sections that have been lost at Alpine. with any questions.

The job log indicates that they were not able to reciprocate the casing and lost a li ttle fluid, but that is not really remarkable. The only well logs I have seen from Alpine where there was questionable cement/isolation were those recent ones where significant lost circulation was experienced. Your proposal to delay the log and initiate water injection is acceptable. This approval is for WATER ONLY. Any change to MI cannot be made until the required bond log has been obtained and submitted to the Commission. Please call with any questions. Tom Maunder, PE AOGCC Jerry C Dethlefs wrote: Tom: As per our discussion over the weekend, I would like approval to delay the SCMT bond log on Alpine well CD2-l8 for a few weeks. Doyon 19 will be moving over the well and there is not enough time to prep the well for injection and perform the bond log prior to the move. By all indications the production casing cement job was successful and the completion was run and tested good. Attached is the cementing summary excerpt from the Daily Drilling Report and the well handover form. Operations would like to get this well on injection as quickly as possible and preferably not wait for the next well to be drilled. Our intent will be to log the SCMT bond log as soon as the drilling rig has again (See attached file: CD2-l8 well handover.xls) (See attached file: CD2-18 Cementing Log.doc)exposed the wellhead. Drop me a line when you get a minute to review this request. Thanks for the help.

'" OR r.Rì'~' J,1 Ii,;. .,' .'/" '; I,.. ~ It,.,.{ /)1 ..,"~ " ' Well Proximity Risks: Directional drilling / collision avoidance information as required by 20 ACC 25.050 (b) is provided in following attachments. CD2-19 will be the closest well to CD2-18. Well separation is 10.5 ft at 300 ft MD. Accounting for survey uncertainty, the ellipse-to-ellipse separation is 5.5 ft at 300 ft MD. CD2-17 is another close approach with 11.5 ft of separation at 400 MD and ellipse-to-ellipse separation of 4.6 ft. DrillinÇl 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 PumpinÇl Operations: Incidental fluids developed trom drilling operations on well CD2-18 will be injected into a permitted annulus on C02 pad or the class 2 disposal well on CD1 pad. The CD2-18 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 CD2-18 form 10-403, Application for Sundry Operations, will be filed. Annular pumping of fluids occurring as a result of 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 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 !

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 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% 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. r' \ O· I~, ."

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]0 Where: ASP = Anticipated Surface pressure in psi FG = Fracture gradient at the casing seat in Iblgal 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) = 3286 - (0.1 x 7262') = 2560 psi 3. Drilling below intermediate casing (7") ASP = FPP - (0.1 x D) = 3281 - (0.1 )( 7252') = 2556 psi '.

The intended spud date for this well is September 15, 2003. It is intended that Doyon Rig 19 be used to drill the well. CD2-18 will be drilled to penetrate the Alpine reservoir horizontally. After setting 7'1 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 injection." . v Note that it is planned to drill the surface hole without a diverter. There have been 38 wells drilled on CD1 pad and 38 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 CD2-18. 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: 1. Form 1 0-401 APPLICATION FOR Permit to Drill per 20 ACC 25.005 (a). 2. Fee of $100 payable to the State of Alaska per 20 ACC 25.005 (c) (1). 3. A proposed drilling program, including a request for approval of annular pumping operations. 4. A drilling fluids program summary. 5. Proposed completion diagram. 6. Proposed completion diagram with open hole isolation options. 7. Pressure information as required by 20 ACC 25.035 (d)(2). 8. Directional drilling / collision avoidance information as required by 20 ACC 25.050 (b). Information pertinent to the application that is presently on file at the AOGCC is: 1. Diagrams of the BOP equipment, diverter equipment and choke manifold layout as required by 20 ACC 25.035 (a) and (b). 2. A description of the drilling fluids handling system. 3.
