Drilling operations on CD4-301 began on 12-09-07 with Doyon 19 (permit no. 207-150) and the well was drilled to the planned landing point in the Kuparuk reservoir. The sand was thinner than expected at the planned landing point, and additional 8-3/4" hole was drilled to confirm formation tops. Unfortunately sand quality and thickness were not ~ sufficient for the well to be economically viable. It was decided to plug back the existing wellbore with cement, and sidetrack to another location north-west of the original landing location. The Nanuq sand will be plugged back with providing +/-100' MD above and below the Kick off plug from +/-10,400' to 9800' MD plugs. cement from13,715' MD to +/-13,115' MD, reservoir penetration. There will also be a with a mud gap between the two cement Since the abandonment plug is planned with sufficient volume to cover +/-245' MD above the Nanuq interval, and another plug is planned to kick off from, ConocoPhillips requests that the requirement to tag the bottom abandonment plug is waived (provided there are no problems during cementing operations). Once the well CD4-301A is kicked off, the 8-3/4" section will be drilled to a new bottom hole location and landed in the Kuparuk sand horizontally. Intermediate casing will then be run and cemented in place. The productive interval will then be drilled horizontally. The well, CD4-301A, will be completed as a slotted liner producer. The 8-3/4" plugged back hole will maintain the name CD4-301and once re-drilled the new sidetracked hole will become CD4-301A with an API extension -01. Please find attached the information: 1. Form 10-403 APPLICATION FOR sundry approval 2. A proposed plug back and drilling program 3. Proposed plug back schematic 4. Actual rig surveys for CD4-301 5.

The well will TD at the same XYs. Although, the intermediate landing point has changed slightly due to dropping the pilot hole.

In accordance with 20 AAC 25.005(fl, all records, data and logs acquired for the pilot hole must be clearly differentiated in both well name (CR CD4-301 PH) and API number (50-103-20557-70) from records, data and logs acquired for well CRU CD4-301. 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. When providing notice for a re esentative of the Commission to witness any required test, contact the Comm' si n's petroleum field inspector at (907) 659-3607 (pager).

Commission Anchorage, Alaska 99501 Anchorage Re: Application for Permit to Drill CD4-301 &CD4-301 PB1 Dear Sir or Madam: ConocoPhillips Alaska, Inc. hereby applies for a Permit to Drill an onshore horizontal producer well from the Nanuq CD4 drilling pad. The intended spud date for this well is 11/11/2007. It is intended that Doyon Rig 19 be used to drill the well. CD4-301 is intended to be a horizontal Kuparuk C sand producer. However, the sand may not be thick enough to drill a horizontal. Therefore a pilot hole, CD4-301 PB1, will be drilled through the Kuparuk sand at 70° to verify if a horizontal well is feasible. The pilot hole will be abandoned with 2 plugs. Then the well, CD4-301, will be kicked off at approximately 11,200' MD and landed in the Kuparuk C sand horizontally. After setting 7" intermediate casing, the horizontal section will be drilled and the well completed as slotted liner producer. The well will be flowed back to mitigate formation damage and then be closed in '~ awaiting completion of well work for the well to begin production. CONTINGENCY PLAN: If the sand and pressures do not allow for a horizontal well, the intermediate °` casing will be run in the pilot hole. The well will be completed as a high angle slant and will be perforated before production. It is expected that both the K2 (Qannik) and the Nanuq sand will be considered a significant hydrocarbon bearing zone. The Nanuq will be cemented 500' above top of the sand. And for the Qannik, it is planned to pump lead cement, then open a stage toot 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) be granted. There have been 19 surface holes drilled at CD4 and there has not been a significant show of shallow gas or gas hydrates. 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 drilling fluids program summary. 4. Proposed pilot hole schematic 5.

Well Proximity Risks: Directional drilling /collision avoidance information as required by 20 ACC 25.050 (b) is provided in following attachments. CD4-302 is the nearest existing well to the CD4-301 plan with 8.6' well to well separation at 523' MD. Drilling Area Risks: There are no high-risk events (e.g. over-pressures zones) anticipated. i Lost circulation: Faulting and low reservoir pressure within the Kuparuk reservoir section is considered to be the most likely cause of lost circulation. Standard LCM material and well bore strengthening pills are 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 Pumoina Operations: Incidental fluids developed from drilling operations on well CD4-301 will be injected into a permitted annulus ~~ on CD4 pad or the class 2 disposal well on CD1 pad. The CD4-301 surface/intermediate casing annulus will be flushed with 300 bbls of fresh water prior to freeze protecting with diesel to 2000' TVD. The significant hydrocarbon zones are the Nanuq, Kuparuk, and the Qannik reservoir. There will be 500' of cement fill above the top of the Nanuq and Qannik reservoirs. Upon completion of CD4-301 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 = 2998 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: OD Wt (ppf) Grade Range Connection Type Collapse 85% of Collapse Burst 85% of Burst 9-5/8" 40 L-80 3 BTC 9,090 psi 1,717 psi 5,750 psi 2,992 psi 7" 26 L-80 3 BTC-Mod 5,410 psi 4,599 psi 7,240 psi 6,154 psi or~siNa~ • DRILLING FLUID PROGRAM SPUD to 9-5/8"surface casing oint - 12 %" Intermediate hole to 7" casing point - 8 3/<<" Production Hole Section - 6 1/8" Density 8.8 - 9.6 ppg 9.6 - 9.8 ppg - 8.8 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 NA HPHT Fluid Loss at 160 (drilling) 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 reservoir 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 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.
