It is constructed with 6 1/8" open hole completion from 12953' to 17513' MD, and 3-1/2" 9.3# L-80 tubing from surface to 12159'MD. It has not been fractured to date. The well will be fracture-stimulated placing approximately 302k# 16/20 CarboLite in six 0-7-PPA stages at 20-bpm. Proposed Procedure: Schlumberger Pumping Services: 1. Conduct Safety Meeting and Identify Hazards. Inspect Wellhead and Pad Condition to identify any pre existing conditions. 2. Ensure all Pre-frac Well work has been completed and confirm the tubing and annulus are filled with a freeze protect fluid to 2,000' TVD. 3. Ensure the 10-403 Sundry has been reviewed and approved by the AOGCC. 4. MIRU 6 clean insulated Frac tanks, with a berm surrounding the tanks that can hold a single tank volume plus 10%. Load tanks with 100° F seawater(approx. 2370 bbls are required for the treatment with breakdown, maximum pad, and 450 bbls usable volume per tank). 5. Ensure lift plan is reviewed and signed prior to RU of Frac equipment requiring lifts. 6. MIRU Stinger Tree Saver Equipment and SLB Frac Equipment. 7. PT Surface lines to 9,000 psi using a Pressure test fluid. ✓ 8. Test IA Pop off system to ensure lines are clear and all components are functioning properly. 9. Pump the 180 bbl breakdown stage (linear gel) according to the attached excel SLB pump schedule. Bring pumps up to maximum rate of 20 BPM as quick as possible, ,/ pressure permitting. Slowly increase annulus (IA) pressure from 2,500 psi to 3,500 psi as the tubing pressures up. Ensure sufficient volume is pumped to load the well with Frac fluid, prior to shut down. 10. Perform a hard shut down, Obtain ISIP and fluid efficiency estimates. 11. Pump the Frac job by following schedule @ 20 bpm with a maximum expected treating pressure of 6200 psi. Stage 1 • 600 bbl Schlumberger fluid Pad • 240 bbl Schlumberger fluid w/2 PPA • 440 bbl Schlumberger fluid w/4 PPA • 230 bbl Schlumberger fluid w/4 PPA • 800 bbl Schlumberger fluid w/7 PPA • Flush with 135 bbl of linear fluid and freeze protect • Total Sand: Approx. 301,500-lb of 16/20 CarboLite Proppant 12. Monitor the surface pressure fall-off at the end of the job for 30 minutes, if the well does not screen out. 13. RDMO SLB Equipment. Freeze Protect the tubing and wellhead if not able to complete following the flush. 14. Well is ready for Post Frac well prep for flowback (Slickline and possibly CTU). Cement Evaluation of CD2-01 and wells within 1/4 mile of CD2-01 CD2-01: 7" Casing cement job was pumped on 9/6/2005 as designed, indicating competent cement operations. The cement pumped was 15.8 ppg Class G cement, displaced by 9.8 ppg mud. The plug was bumped @ 1,100 psi and floats held. CD1-30: 7" Casing cement job was pumped on 9/26/2000 as designed, indicating competent cement operations. The cement pumped was 15.8 ppg Class G cement, displaced by 9.6 ppg mud. The floats held. CD1-31: 7" Casing cement job was pumped on 9/8/2000 as designed, indicating competent cement operations. The cement pumped was 15.8 ppg Class G cement, displaced by 9.8 ppg mud. The floats held. CD2-08: 7" Casing cement job was pumped on 1/30/2003 as designed, indicating competent cement operations. The cement pumped was 15.8 ppg Class G cement, displaced by 9.9 LSND ppg mud. The plug was bumped @ 1,300 psi and floats held. Full returns maintained throughout the job. Summary Based on engineering evaluation of the wells referenced in this application, ConocoPhillips has determined that this well can be successfully fractured within its design limits. It has also been determined that the frac will not adversely affect wells within a % mile radius or other nearby well. • • c o ck ¢ k3»»> d 2 O E •a a ` ov,tiaZZZZZ .a �W 0. 2 to aaaa ca Ga Qb, 2¢ Eamm - m(3z ¢ e > a RW z . 0, 3ooc.) yZaoo >.sscnava0=___¢¢ Q LL.uZZOWc a � O fn Z rn `m� Dm + • • • . . . . . . . • • . » m .

We trend the pressure response from there as the formation naturally de-pressures and assume the frac discontinues to grow. From there we determine ISIP or instantaneous shut-in pressure. We also use frac design modeling software such as SLB's FracCADE, and others such as GOHFER, and StimPlan,to help interpret the data and analyze reservoir parameters such as closure pressure, fluid efficiency and leak off rate. With this data we may optimize the main frac treatment with respect to pad volume and/or proppant stage increases or decreases. I don't remember the calculations for fluid efficiency; I would need to look them up in a reference again, but the plots generated are generally the Nolte plot,the Nolte log-log, and then square-root of shut-in time plots. Let us know if you have any additional questions. Regards, Mike Mike Hazen Wells Engineer—ConocoPhillips Alaska, Inc.

This well is an open hole style completion with 3.5" tubing. It has not been fractured to date. We intend to stimulate the Alpine C formation with a single stage treatment of the open hole section. If the stimulation is successful we intend to place -300,000#'s of 16/20 Carbolite and anticipate an increased production of 150 bpd in 2013. Proposed Procedure: Schlumberger Pumping Services: (Alpine C Frac) 1. Conduct Safety Meeting and Identify Hazards. Inspect Wellhead and Pad Condition to identify any pre existing conditions. 2. Ensure all Pre -frac Well work has been completed and confirm the tubing and annulus are filled with a freeze protect fluid to 2,000' TVD. 3. Ensure the 10 -403 Sundry has been reviewed and approved by the AOGCC. 4. MIRU 7 clean insulated Frac tanks, with a berm surrounding the tanks that can hold a single tank volume plus 10 %. Load tanks with 100° F seawater (approx. 4950 are required for the treatment with breakdown, maximum pad, and 450 bbls usable volume per tank). 5. Ensure lift plan is reviewed and signed prior to RU of Frac equipment requiring lifts. 6. MIRU Stinger Tree Saver Equipment and SLB Frac Equipment. 7. PT Surface lines to 8,000 psi using a Pressure test fluid. 8. Test IA Pop off system to ensure lines are clear and all components are functioning properly. 9. Pump the 300 bbl breakdown stage (25# linear gel, WF125) according to the attached excel SLB pump schedule. Bring pumps up to maximum rate of 40 BPM as quick as possible, pressure permitting. Slowly increase annulus pressure from 2,500 psi to 3,500 psi as the tubing pressures up. Ensure sufficient volume is pumped to load the well with Frac fluid, prior to shut down. 10. Perform a hard shut down, Obtain ISIP and fluid efficiency estimates. 11. Pump the Frac job by following schedule @ 40bpm with a maximum expected treating pressure of 3700 psi. Stage 1 • 600 bbls YF125ST Pad • 240 bbls YF125ST w/ 2 ppa 16/20 Carbolite • 480 bbls YF125ST w/ 4 ppa 16/20 Carbolite • 2400 bbls YF125ST w/ 4 ppa 16/20 Carbolite • 800 bbls YF125ST w/ 7 ppa 16/20 Carbolite • Flush with 150 bbls of linear fluid (WF125) and freeze protect • Total Sand: Approx. 300,000 lbs 16/20 Carbolite 12. Monitor the surface pressure fall -off at the end of the job for 30 minutes, if the well does not screen out. 13. RDMO SLB Equipment. Freeze Protect the tubing and wellhead if not able to complete following the flush. 14. Well is ready for Post Frac well prep for flowback (Slickline and possibly CTU). RB • • 15. Flowback will be initiated through Expro until the fluids clean up at which time it will be turned over to production. (initial flowback fluids to be taken to appropriate disposal well until they are clean enough for production.) Cement Evaluation of CD2 -01 and wells within' /4 mile of CD2 -01 CD2 - 01: 7" Casing cement job was pumped on 9/6/2005 as designed, indicating competent cement operations. The cement pumped was 15.8 ppg Class G cement, displaced by 9.8 ppg mud. The plug was bumped @ 1,100 psi and floats held. CD1 - 30: 7" Casing cement job was pumped on 9/26/2000 as designed, indicating competent cement operations. The cement pumped was 15.8 ppg Class G cement, displaced by 9.6 ppg mud. The floats held. CD1 - 31: 7" Casing cement job was pumped on 9/8/2000 as designed, indicating competent cement operations. The cement pumped was 15.8 ppg Class G cement, displaced by 9.8 ppg mud. The floats held. CD2 - 08: 7 Casing cement job was pumped on 1/30/2003 as designed, indicating 9 job p p g competent cement operations. The cement pumped was 15.8 ppg Class G cement, displaced by 9.9 LSND ppg mud. The plug was bumped @ 1,300 psi and floats held. Full returns throughout the job. Summary Based on engineering evaluation of the wells referenced in this application, ConocoPhillips has determined that this well can be successfully fractured within its design limits. It has also been determined that the frac will not adversely affect wells within a %4 mile radius or any other nearby well. RB • • Stimulation Surface Rig -Up z u. \ 11 \ .

Tom Maunder, PE AOGCC Johnson, Vern wrote, On 9J12J2005 3:56 PM: Tom, As discussed on the weekend, we made the decision to sidetrack CD2-01. After drilling out of 7" casing (12953' MD), we drilled to 14825' MD after drilling out of the top of the Alpine C formation at 14742' MD. We pulled back and open hole sidetracked the well at 14700' MD leaving ± 42' of sand in the "abandoned" leg. Due to the reason for the sidetrack and the relatively short interval, I propose we consider the "abandoned" hole to be a plug back, PB2 with API suffix -71.

This revision is necessary since the proposed bottomhole location has been changed by more than 500' laterally due to encountering thinner than expected sands along the original trajectory. In accordance with 20 AAC 25.005(f~, all records, data and logs acquired for the originally plugged back wellbore section must be clearly differentiated in both name (CD2-01 PB 1 } and API number (50-103-20514-70) from records, data and logs acquired from CD2-01. This permit to drill does not exempt you from obtaining additional permits or approvals 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. Please provide at least twenty- four (24) hours notice for a representative of the Commission to witness any required test. Contact the Commission's petroleum field inspector at (907) 659- 3607 (pager). • DATED this day of September, 2005 cc: Department of Fish 8s Game, Habitat Section w/o encl.

Drilling operations on CD2-01 began on 8-22-05 with Doyon 19 (permit no. 205-118) and the well was drilled to the planned landing point in the Alpine reservoir. The sand was thinner than expected at the planned landing point, and additional 8-1/2" hole was drilled horizontally to confirm formation tops and check if the sand became thicker further along the planned wellbore. 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. After plugging back above the Alpine C with cement, a kick off plug will be set from +/- 10440' MD to 11040' MD. It is planned to kick off from 10640' ~MD and re-drill the intermediate section of CD2-01. The intermediate section will be drilled and landed in the Alpine sand horizontally; 7" casing will then be run and cemented in place. CD2-01 will be completed as an openhole producer. 'At the end of the work program the well will be shut in awaiting slickline well work and surface connection. The originally drilled 8-1/2" hole will be re-named CD2-01PB1 with API extension -70 and the new sidetracked hole will become CD2-01. If insufficient sand is found when drilling the second intermediate hole, the well will be plugged and abandoned. 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. Fee of $100 payable to the State of Alaska per 20 ACC 25.005 (c) (1). 3. A proposed plug back and drilling program 4. Proposed completion diagram. 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 (a). Also, a copy of the CD2-01 PB1 surveys are included. Information pertinent to this 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. Diagram of riser setup which replaces diverter If you have any questions or require further information, please contact Vern Johnson or 265-6081, respectively.

CD2-02 will be the closest well to CD2-01. Well separation is 5.7' @ 275' MD. Accounting for survey uncertainties, the ellipse-to-ellipse separation is 4.9' @ 275' MD. Drilling 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. 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 Pumping Operations: Incidental fluids developed from drilling operations on well CD2-01 will be injected into a permitted annulus on CD2 pad or the class 2 disposal well on CD1 pad. The CD2-01 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 CD2-01 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)'` (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: OD Wt (ppf) Grade Range Connection Type Collapse 85% of Collapse Burst 85% of 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 ui~IGINAL CD2-01 DRILLING FLUID PROGRAM • SPUD to 9-5/8"surface casing oint -12 '/4" Intermediate hole to 7" casing point - 8 %2" Production Hole Section - 6 1/8" Density 8.8 - 9.6 ppg 9.6 - 9.8 ppg 8.1-8.8 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 (drilling) NA 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% Oil /water ratio Approx. 80/20 Surface Hole: A standard high viscosity fresh water J gel spud mud is recommended for the surface interval. Keep flowline viscosity at ± 200 sec/gt 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 9.6 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 80/20 oil/water ratio M-I Versa-Pro mineral oil based drill-in fluid. The base fluid will consist of high flashpoint (>200 F) mineral oil with 25% by weight calcium chloride as the internal phase. Calcium carbonate bridging material will be added to minimize formation damage.
