This permit to drill does not exempt you from obtaining additional permits or an approval required by law from other governmental agencies and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit.

The main bore of the well will be designated CD4-25 and the second lateral of the well will be designated as CD4-25L1. The planned spud date for this well is 09/6/2010. Doyon Rig 19 will be used to drill the well. After setting 7-5/8" intermediate casing,the first horizontal section, CD4-25,will be drilled and the well lined with blank liner and perforated pups in the Alpine A sand. The CD4-25L1 lateral will drilled off a whipstock into the Alpine C sand and lined with blank and slotted liner. Blank and slotted liner placement is dependant on excursions out of zone while drilling the laterals. The well will then be closed in awaiting completion of well work and facilities connection that will allow the well to be placed on production. It is expected that the K2 (Qannik)sand will be considered a significant hydrocarbon bearing zone in this area. After running 7- .— 5/8"casing, lead cement will be pumped to cover the lower hydrocarbon bearing intervals,then a second stage cement job will be pumped through a stage tool 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). 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. Riser setup If you have an estions or require further information, please contact Mike A.Winfree at 265-6820. Sincerely, Mike A.

CD4-25 will be the closest approach while drilling the CD4-25L1wp12. There is ellipse overlap from 16,100' MD to 16,150' MD. There is sufficient geologic control to mitigate the risk of colliding with the CD4-25 wellbore. The CD4-25 lateral will be drilled in the Alpine A sand which is prognosed to be —95' TVD feet below the bottom of the Alpine C sand which is the CD4-25L1 target. 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 CD4-25L1 will be injected into a permitted annulus on CD4, or the class 1 disposal well on CD1 pad. Upon completion of CD4-25L1, 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. 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 DRILLING FLUID PROGRAM Production Hole Section—6 3/4" Density 8 8g PV 15—22 YP 25—30 Funnel Viscosity Initial Gels 9— 12 10 minute gels 10 - 14 API Filtrate HPHT Fluid Loss at 160 <5 cc/30 min PH OWR 80/20 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.

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) = 1,086-(0.1 x 2,400') = 846 psi 2. Drilling below surface casing (10-3/4") ASP= [(FG x 0.052)-0.1] D = [(14.5 x 0.052)-0.1] x 2,400 = 1,570 psi OR ASP= FPP-(0.1 x D) = 3,434-(0.1 x 7,588) =2,675 psi 3.

Guy Schwartz Senior Petroleum Engineer AOGCC 793-1226 (office) 444-3433 (cell) From: Winfree, Michael Alex(Jr.) [mailto:Michael.A.Winfree @conocophillips.com] Sent: Monday, August 30, 2010 2:38 PM To: Schwartz, Guy L (DOA) Subject: CD4-25 Permit to Drill Re-Issue Statement Guy, The original CD4-25 well was submitted as an Alpine A Sand single lateral horizontal producer for the PTD, and was approved in November 2009 (permit number 50-103-20608-00). 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.
