The well was completed with 3.5" tubing. It was hydraulically April of 2006, 140,000 #'s of 16/30 Badger Sand was placed. We intend to re- 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 240 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 • 700 bbls YF125ST Pad • 260 bbls YF125ST w/ 2 ppa 16/20 Carbolite • 500 bbls YF125ST w/ 4 ppa 16/20 Carbolite • 200 bbls YF125ST w/ 4 ppa 16/20 Carbolite • 800 bbls YF125ST w/ 7 ppa 16/20 Carbolite • Flush with 160 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.) 3 Cement Evaluation of CD2-4g and wells within 1 /4 mile of CD2 -43 CD2 - 43: 7" Casing cement job was pumped on 1/9/2004 as designed, indicating competent cement operations.

A screen out occurred (40% of desired volume), but was still considered a successful stimulation. Another treatment will be p erformed in the OH horizontal section to establish communication in another art of the completion. A coil cleanout p P v' will only be performed should it be necessary post -frac. Procedure: 1. MIRU seven clean insulated frac tanks with a berm surrounding the tanks that holds the tank volume plus 10 %. Load tanks with seawater from the injection system (approximately 4000 bbls are required for the treatment) 2. Rig up Schlumberger equipment and stab Tree Saver. (Test tree saver seals to expected pressure using warm diesel to assure seal integrity in tubing hanger). 3. Pressure test surface lines to 9500 psi 4. Pump the 100 bbl Breakdown with Schlumberger's YF125ST fluid system. Bring pumps up to maximum rate ASAP. 5. Pump the following schedule at 20 -25 BPM with a maximum pressure of 9000 psi, add breaker as per lab results. Maintain 3000 psi on the IA during the treatment. • 1000 bbls YF125ST Pad • 500 bbls YF125ST w/ 2 ppa 16/30 White Sand • 1200 bbls YF125ST w/ 4 ppa 16/30 White Sand • 600 bbls YF125ST w/6 ppa 16/30 While • 600 bbls YF125ST w/ 7 ppa 16/30 White Sand • Flush with linear fluid and freeze protect Total Sand: —450,000 lbs. 6. Monitor the surface pressure fall -off at the end of the job for 30 min (or until closure is verified) if the well does not screen out. 7. Rig down equipment, (and prep for next well frac after evaluation by Engineering) move off location. FCO if required with slick diesel. • .~.._ :.h: MICROFILMED 43/01 /2008 DO NOT PLACE ANY NEW MATERIAL UNDER THIS PAGE F:1LaserFiche\C~+rPgs_Inserts~Microfilm_Marker. doc , . . ~ ConocoPhillips Alaska V¡{lP 7, ~ P.O.

March 24, 2007 Mr. Tom Maunder Alaska Oil & Gas Commission 333 West ih Avenue, Suite 100 Anchorage, AK 99501 'Jlß-¡q7 Dear Mr. Maunder: Enclosed please find a spreadsheet with a list of wells ITom the Alpine field (ALP). Some of these wells were found to have a void in the conductor by surface casing annulus. The voids that were greater than 3 feet were first filled with cement to a level of approx. 1.0 foot. The remaining volume of annular void respectively was coated with a corrosion inhibiter, RG2401 engineered to prevent water ITom entering the annular space. As per previous agreement with the AOGCC, this letter and spreadsheet serves as notification that the treatments took place and meets the requirements of form 10-404, Report of Sundry Operations. The cement top-fill operation was completed on March 21st, 2007. Schlumberger Well Services mixed 15.7 ppg Arctic set I in a blender tub.

This will increase the wells production rate and reserves. A coil cleanout will only be performed should it be necessary post-frac. Procedure: 1. MIRU seven clean insulated frac tanks with a berm surrounding the tanks that holds the tank volume plus 10%. Load tanks with seawater from the injection system (approximately 2500 bbls are required for the treatment) 2. Rig up Dowell equipment and stab Tree Saver. (Test tree saver seals to expected pressure using warm diesel to assure seal integrity in tubing hanger). 3. Pressure test surface lines to 9500 psi 4. Pump the 100 bbl Breakdown with Dowell's YF125ST fluid system. Bring pumps up to maximum rate ASAP. 5. Pump the following schedule at 30 BPM with a maximum pressure of 9000 psi, add breaker as per lab results. Maintain 3000 psi on the IA during the treatment. -"..'.....................-------.. · 300 bbls YF125ST Pad · 240 bbls YF125ST w/2 ppa 16/30 White Sand · 480 bbls YF125ST w/4 ppa 16/30 White Sand · 1000 bbls YF125ST w/7 ppa 16/30 White Sand · Flush with linear YF125ST and freeze protect Total Sand: -310,000 Ibs. 6. Monitor the surface pressure fall-off at the end of the job for 30 min (or until closure is verified) if the well does not screen out. 7. Rig down equipment, (and prep for next well frac after evaluation by Engineering) move off location. FCO if required with slick diesel.

We will 81 the well on July 8th as required and plan to wash the 8CSSV once the rig completes the C02-60 and moves to the other end of the CD2 pad. The rig move is tentatively scheduled for July 10th. CT will be rigged up ASAP to attempt to clean the SCSSV. If the CT wash is unsuccessful, we will lock-out the SCSSV and install a WL retrievable SV. Let me know if you need any additional information for Tom. Thanks for your assistance on this.

It was tested and passed on 4/9/04 & 3/21/05 After C02-43's SSSV failed on 4-3-05, an extensive amount of diagnostic wellwork has been completed. A video log of the SSSV showed the flapper closed with no indication of why the flapper isn't sealing and holding back well pressure. The leak rate thru the closed flapper is the well's production rate, the flapper is not choking back well production. It is not clear if the SSSV flapper is damaged or if debris is preventing it from sealing. The tools to lock out the SSSV and install a WRDP SSSV were purchased recently, but this work is pending an attempt to wash the SSSV profile with CTU. At this time, Alpine is facility limited, so the well has been SI since 4/13/05 waiting on a potential decision to sidetrack the well later this year. The sidetrack will require pulling the tbg, thus replacing the SSSV. Prior to the CD2-60PB1 pressure event last weekend, CD2-43 was to be SI due to facility limits until the rig arrived. If production of CD2-43 is successful on reducing reservoir pressure, wellwork will be completed to either repair the SSSV or lock it out and install a WRDP within 30 days or the well will be 81. History on SSSV diagnostic work: 03/21/05: SSSV failed test 04/03/05: SSSV failed retest. 04/04/05: Well SI. SL brushed SSSV, unable to pass closure test 04/05/05: SL brushed and flushed SSSV, flow tube moving, but unable to pass closure test 04/09/05: SL set wash tool in SSSV profile (wash tool as nozzles designed to wash debris from SSSV profiles). Pumped 65 bbls diesel thru wash tool. Unable to pass closure test. Brought well on line, closed SSSV with well flowing, no drop in tbg pressure. SI well, unable to bleed off tbg pressure. Left well flowing overnight in an attempt to clean up SSSV. 04/10/05: SI well, SL ran flapper checker, flapper partly closing. Worked SSSV flow tube with friction tool. Closure test failed. Bled tbg from 1700 psi to 1150 psi, tbg pressure built 200 psi in 10 mins. 04/13/05: PUMPED HOT DIESEL & BRUSHED FLAPPER. ABLE TO CATCH & RELEASE BRUSH INDICATING SOME FLOW TUBE MOVEMENT. RAN FRICTION TOOL, HAD SOME INCONCLUCIVE EVIDENCE OF FLOW TUBE MOVEMENT. PERFORMED SEVERAL CLOSURE TESTS, ALL FAILED. Bled tbg down from 725 to 400 psi, tbg up to 650 psi after 6 míns, up to 725 psi after 8 míns. 04/14/05: PUMPED 30 BBLS OF HOT DIESEL DOWN TBG. RAN FRICTION TOOL. MADE NUMEROUS STROKES ON FLOW TUBE. SAW MOVEMENT ON MARTEN DECKER & CONTROL LINE. ATTEMPTED CLOSURE TEST WHILE STROKING FLOW TUBE UP W/ FRICTION TOOL, STILL FAILED. MADE TWO ATTEMPTS FOR CLOSURE TEST VIA PRODUCTION, BOTH FAILED BADLY. 04/23/05: COMPLETED VIDEO LOG OF SSSV. DISPLACED TBG PAST SSSV WI LIFT GAS. PRELIMINARY ANALYSIS OF VIDEO SHOWS THAT FLOW TUBE IS NOT TRAVELING ALL THE WAY DOWN AND LEAVES FLAPPER EXPOSED TO FLOW. ALSO SHOWS SOME TRASH ON ONE SIDE OF THE LOWER SEAT OF FLOWTUBE.

Flow rates are expected to drop to a range where paraffin build up may be a problem. Additional centralizers were used on the 7" casing run to increase standoff through the permafrost (see attached 7" casing detail). It is expected that this will reduce heat loss to the permafrost. The 9-5/8" casing x 7" casing annulus is a to be Arctic packed to reduce convection currents in the annular space. This should reduce heat transfer to the permafrost, which will reduce paraffin build up in the tubing string. Procedure 1. Meet with Alpine Operator (x4222) to discuss any potential conflicts arising while over the well. Review CD-2 Pad Emergency, Spill and Contingency plans. Hold Safety meeting with all associated personnel. Note - the Alpine Simultaneous Operating Policy (SimOps V.1 dated 1/4/2000) is the guideline for coordination of multiple operations on any Alpine Well Pad. Note - to meet ADEC Air Emission Permit stipulations all slickline, eline, pump trucks and hot oil truck operations are monitored on the basis of fuel consumption that must be measured and recorded daily. Contact Alpine Regulatory Compliance. 2. Visually inspect the well. Record tubing pressure, IA pressure, and OA pressure. 3. Contact MI to prepare the fluids per the attached recipe. MI is aware that the job is coming up. a. Arrange for +/-85_bbls of L VT 200 mineral oil be available at the Prudhoe Bay MI plant. Verify volumes with MI in advance. b. MI will blend the base mix for shipment and organophillic clays for final mix. c. Arrange vac truck to transport base mix to Alpine. d. DS will provide blender/pump truck combo to mix and pump mix. e. Onsite blend the base fluids with organophillic clays to set the gels and finalize the blending. 4. RU on the 9-5/8" x 7" casing annulus (OA). Be sure Dowell has a valve to use as a working valve. Pump an annular volume of diesel to verify the annulus is open. The annulus has broken down at 13.1 ppg equivalent in the past, see attached annulus test. If surface pressure approaches 1200 psi, stop pumping and call Vern Johnson at 907-748-3906 (cell). With gas 2 ) ') in the 7" x 9-5/8" annulus the 80 % collapse limit of the 7" is close to 1200 psi surface pressure. 5. Pump +/- 85 bbl. of L VT -200 arctic pack down the annulus at 2-3 bpm to sweep the old annulus fluids ahead. If surface pressure approaches 1200 psi, stop pumping. Chase with 1-2 bbl. of neat diesel. 6. RD DS. a. Ship 30-50 bbl. of clean diesel to MI to clean tanks and lines. b. Return the vac trucks to MI to load and dispose of spent diesel and rinseate. c.

CD2-44 will be the closest well to CD2-43. Well separation is 9.8' at 400' MD. Accounting for survey uncertainties, the ellipse-to-ellipse separation is 2.8' at 400' MD. DrillinÇl Area Risks: There are no high-risk events (e.g. over-pressures zones) anticipated. j 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 PumpinÇl Operations: Incidental fluids developed from drilling operations on well CD2-43 will be injected into a permitted annulus J on C02 pad or the class 2 disposal well on CD1 pad. The CD2-43 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 CD2-43 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: Wt Connection 85% of 85% of OD (ppf) Grade Range Type Collapse Collapse Burst 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 CD2-43 ) DRilLING FLUID PROGRAM I· , ) SPUD to Intermediate hole to 7" Production Hole 9-5/8"surface casing casing point - 8 Y2" Section - 6 1 18" point - 12 %" Density 8.8 - 9.6 ppg 9.6 - 9.8 ppg 8.1-8.8 ppg .........

Keep flowline viscosity at ± 200 seclqt 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 I 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 a 80/20 oillwater 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.

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]D Where: ASP = Anticipated Surface pressure in psi FG = Fracture gradient at the casing seat in Ib/gal 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.
