Winfree 265 -6820 or Dave Burley at 670 -4300 Operations Summary: 6 -3/4" production hole was TD'd. Backreamed to the 7 -5/8" casing shoe. Monitored well at the shoe and the well bore appeared to be breathing. An exhale test was performed to confirm breathing. The upper pipe rams were functioned to shut in the well. The following pressures were observed CP = 18 psi DP = 34 psi. The rams were opened and flow from the well was observed to decrease to 0.25 bph before the rams were functioned closed again and the following pressures observed CP = 10 psi DP = 0 psi. BOPE Used: Upper Pipe Rams Reason for BOPE Use: Perform exhale test to confirm well bore breathing Actions to be Taken: Test upper pipe rams after pulling out of hole with drilling BHA. Please let me know if you require additional information regarding our exhale test at CD4 -25. Thank You, Mike A.

The advantage to setting casing in the B shale is that it minimizes the exposure time from first cutting the unstable Miluveach shale to getting it cased. Below is the proposed procedure: 1. Continue sidetracking off of plug at 13,200' MD 10/12/2010 • Page 2 of 2 2. Drill to 16,700' MD ( -622' MD shallower than planned) 3. Condition hole for casing run 4. POOH with drilling assembly 5. RU and run 7 -5/8" The shallower casing point is planned to reduce shale exposure time by 14 -18 hours. Operationally the production drill out, lower completion, window milling, drilling and completing the upper lateral and running upper completion will operationally be the same, only the depths will have changed. The well is planned as a dual lateral producer and I am unaware of any regulatory issues with the proposed plan outlined above. Please advise if the proposed plan forward is in compliance with State regulations or requires additional information to proceed.

G.Robertson ©conocophillips.comJ Sent: Friday, September 24, 2010 10:10 AM To: Schwartz, Guy L (DOA) Cc: Winfree, Michael Alex (Jr.) Subject: RE: CD4 -25 Kuparuk Cement Plug and Kick Off Plug (PTD 209 -150) Guy, As per your conversation with Mike Winfree Jr... Doyon 19 was able to work the 3.5" cement stinger to a depth of 14,871' MD over the course of the evening, however deteriorating hole conditions prevented running the stinger past this point to the intended cementing point of 14,941' MD. In addition, the cement stinger was temporarily stuck in the hole at this depth for several hours before the crews were able to work it free. Once free, the stinger was pulled to a depth of 14,805' MD, and the crews were able to reciprocate and circulate without issue. Below is the revised proposal to isolate the Kuparuk C formation, which is driven by the concern that attempting to work the cement stinger to 14,941' MD below the base of the Kuparuk will result in stuck pipe. Proposed Plan Forward: 1. Set 15.8 ppg Class G balanced plug from 14,805' MD to 14,522' MD (300' MD above the Kuparuk sand) 2. Circulate above plug and pull stinger up to 13,850' MD and set hi viscosity gel pill 3. Rig up and pump densified 17.0 ppg balanced plug from 13,550' MD to 13,150' MD. (Planned kick off point is 13,450' MD) 4. Pull out of hole and lay down cement stinger 5. Pick up drilling BHA and run in hole and tag kick off plug 6. Begin sidetrack operations. See the revised CD4 -25 Cement Plug Placement schematic that is attached for additional information.

It is not necessary to tag the Kuparuk zone cement plug as long as the operation goes as planned. You have a semi "base" (collapsing shale) to lay in the plug from and there is little doubt that it will be isolated as it is a small zone TVD wise. If your tag depth of the "kick off' plug comes in a lot different that expected please notify me right away. As we discussed this Plugback becomes CD4 -25PB1 and has a API number ending in -70 operations and log data for this lateral should be included in the final 407 report when the well is finished.

ORIGINAL • • Well Proximity Risks: Directional drilling / collision avoidance information as required by 20 ACC 25.050 (b) is provided in the following attachments. CD4 -24 is the nearest existing well to CD4- 25wp12. Ellipse to ellipse separation is 13.47' at 523' MD. Drilling Area Risks: Unstable Shales: Intermediate hole sections in this area have shown shale instability at lower mud weights. Plan to use mud weight sufficient to stabilize shales based on offset data. Lost circulation: - Faulting within the Alpine reservoir section is considered to be the most likely cause of lost circulation. Standard LCM material is expected to be effective in dealing with lost circulation. Annular Pumping Operations: Incidental fluids developed from drilling operations on well CD4 -25 will be injected into a permitted annulus on CD4, or the class 1 disposal well on CD1 pad. The CD4 -25 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 Qannik reservoir and there will be 500' of cement fill above the top of the Qannik as per regulations. Upon completion of CD4 -25, 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 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 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) * (2,400') + 1,500 psi = 2,997 psi Pore Pressure = 1,086 psi Differential = 2997 —1086 = 1911 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 10 -3/4" 45.5 L -80 3 BTC -M 2,480 2,108 psi 3,580 psi 3,043 psi 7 -5/8" 29.7 L -80 3 BTC -M 4,790 psi 4,071 psi 6,890 psi 5,856 psi ORIGINAL . .

Keep flow line 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. Maintain mud weight at or below 9.8 ppg and plan to weight up to 11.0 ppg for lower shale stability. 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 drill -in fluid for Alpine producer wells will be a 80/20 oil /water ratio VERSAPRO mineral oil based drill -in - fluid designed to minimize filter cake lift off pressure. The base fluid will be high flashpoint ( >200° F), low aromatics, LVT -200 mineral oil. The internal phase will consist of 33% by weight CaCl2 brine with emulsifiers and wetting agents. SAFE -CARB 2 and S -200 calcium carbonate will be used as a bridging agent for proper filter cake building and fluid loss control.

When CD4 -24 penetrated a high quality Alpine C Sand 2,000' to the east of the proposed CD4 -25 bottom hole location it was decided to optimize the well completion to enable full drainage of both sands with one well. The desire to access both the A and C Sand reserves in this location necessitated the addition of a second lateral. The proposed CD4 -25 bottom -hole location was between two existing wells in which both the Alpine A and C Sand are present. In this location the C Sand is near sub- seismic, however CD4 -24, the well to the east, penetrated 35' of gross C Sand so a change in bottom hole location was required to optimize the well spacing for both laterals. Please let me know if you need additional information regarding the CD4 -25 application for a Permit to Drill. Thanks, -Mike Mike A.

ColnniSSiGn Alaska Oil and Gas Conservation Commission Anchorage 333 West 7 Avenue, Suite 100 Anchorage, Alaska 99501 Re:Application for Permit to Drill CD4 -25 Dear Sir or Madam: ConocoPhillips Alaska, Inc. hereby applies for a Permit to Drill an onshore oil production well from the CD4 drilling pad. The intended spud date for this well is 12/21/09. It is intended that Doyon Rig 19 be used to drill the well. After setting 7 -5/8" intermediate casing, the horizontal section will be drilled and the well completed with pre - perforated pups and blank liner. At the end of the rig work program, the well will be flowed back for 2 -3 days to mitigate reservoir damage prior to being put on production. It is expected that the K2 (Qannik) sand will be considered a significant hydrocarbon bearing zone. After running 7 -5/8" casing, it is planned to pump lead cement, then open a stage tool and pump a second cement job to isolate the K2 with 500' of cement above and below the interval. This will leave a mud gap between the two stages. It is requested that a waiver of the diverter requirement under 20 AAC 25.035 (h)(2) is granted. At CD4, there has not been a significant show of shallow gas or gas hydrates through the surface hole interval. 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 10 -401 Application for Permit to Drill per 20 ACC 25.005 (a). 2. A proposed drilling program. 3. A proposed completion diagram. 4. A drilling fluids program summary. 5. Pressure information as required by 20 ACC 25.035 (d)(2). 6. Directional drilling /collision avoidance information as required by 20 ACC 25.050(b). • 1 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 lay out as required by 20 ACC 25.035 (a) and (b). 2. A description of the drilling fluids handling system. 3.

ORIGINAL • • Well Proximity Risks: Directional drilling / collision avoidance information as required by 20 ACC 25.050 (b) is provided in following attachments. CD4 -26 is the nearest existing well to the CD4 -25 plan at 19' well to well separation at 300' MD. Drilling Area Risks: There are no high -risk events. Lost circulation: Faulting within the Alpine reservoir section is considered to be the most likely cause of lost circulation. Standard LCM material is expected to be effective in dealing with lost circulation. 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 Pumping Operations: Incidental fluids developed from drilling operations on well CD4 -25 will be injected into a permitted annulus on CD4, ° or the class 1 disposal well on CD1 pad. The CD4 -25 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 Qannik reservoir and there will be 500' of cement fill above the top of the Qannik as per regulations. Upon completion of CD4 -25 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) * (2400') + 1,500 psi = 2,997 psi Pore Pressure = 1,086 psi Therefore Differential = 2,997 —1,086 = 1,911 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 10 -3/4" 45.5 L -80 3 BTC -M 2,480 psi 2,108 psi 5,210 psi 4,428 psi 7 -5/8" 29.7 L -80 3 BTC -M 4,790 psi 4,071 psi 6,890 psi 5,856 psi O • • DRILLING FLUID PROGRAM SPUD to Intermediate hole to Production Hole 10 -3/4 "surface casing 7 -5/8" casing point — Section — 6 3/4" point— 13 -1/2" hole 9 -7/8" hole Density 8.8 — 9.6 ppg 9.6 — 9.8 ppg 9.2 ppg PV 10 — 25 10 —15 YP 20 -60 15 -25 25 -30 Funnel Viscosity 100 — 200 Initial Gels 4 — 8 10 —15 10 minute gels <18 12 - 20 API Filtrate NC — 10 cc / 30 min 4 — 12 cc /30 min (drilling) HPHT Fluid Loss at 160 12 - 14 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 flow line 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 Nechelik 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 interval will be drilled with a M -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.
