Drilling operations on CD4-301A began on December 21st with Doyon 19 (permit no. 207-174). On December 23`d operations encountered an over pressured Kuparuk formation. Per well control guidelines, CD4-301A was shut in & monitored at surface. Circulation was shortly resumed following stabilized well conditions at which time the wellbore packed off and circulation was lost resulting in stuck pipe at 15,307' MD. Following 6 days of attempting to free the stuck pipe, a cut was made just above the BHA at 13,445' MD. The drill pipe was removed from the hole with approximately 1,875' BHA with two radioactive sources left in the hole. It was decided to plug back the existing wellbore with cement, and sidetrack to another location west of the previous landing location. The Nanuq sand will be plugged back with cement from +/- 12,700' MD to the top offish at +/-13,430' MD, providing +/-100' MD above the reservoir penetration. There will also be a Kick off plug from +/-9,400' to 10,000' MD with a mud gap between the two cement plugs. The abandonment plug is planned to cover +/-100' MD above the Nanuq interval and 700' MD above the top of fish. The abandonment plug will be tagged. Once the well CD4-301 B 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. CD4-301 B will be suspended as Doyon 19 prepares to move over to CD3 for winter drilling operations. The productive interval will be completed in the spring by Doyon 19 or 141 and will then be drilled horizontally. The well, CD4-301 B, will be completed as a slotted liner producer. The 8-3/4" plugged back hole will maintain the name CD4-301Aand once re-drilled the new sidetracked hole will become CD4-301 B with an API extension -02. Please find attached the information: 1.

Drilling operations on CD4-301A began on December 21st with Doyon 19 (permit no. 207-174). On December 23~d operations encountered an over pressured Kuparuk formation. Per well control guidelines, CD4-301A was shut in & monitored at surface. Circulation was shortly resumed following stabilized well conditions at which time the wellbore packed off and circulation was lost resulting in stuck pipe at 15,307' MD. Following 6 days of attempting to free the stuck pipe, a cut was made just above the BHA at 13,445' MD. The drill pipe was removed from the hole with approximately 1,875' BHA with two radioactive sources left in the hole. It was decided to plug back the existing wellbore with cement, and sidetrack to another location west of the previous landing location. The Nanuq sand will be plugged back with cement from 12,700' MD to the top of fish at +/-13,430' MD, providing +/-100' MD above the reservoir penetration. There will also be a Kick off plug from +/-9,400' to 10,000' MD with a mud gap between the two cement plugs. The abandonment plug is planned to cover +/-100' MD above the Nanuq interval and 700' MD above the top of fish. The abandonment plug will be tagged. Once the well CD4-301 B 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. CD4-301 B will be suspended as Doyon 19 prepares to move over to CD3 for winter drilling operations. The productive interval will be completed in the spring by Doyon 19 or 141 and will then be drilled horizontally. The well, CD4-301 B, will be completed as a slotted liner producer. The 8-3/4" plugged back hole will maintain the name CD4-301Aand once re-drilled the new sidetracked hole will become CD4-301 B with an API extension -02. ~' Please find attached the information: 1.

The intended start date for this work is 12/19/2007. Operations for CD4-301 began on December 9th, 2007 with Doyon 19 and on December 18th TD was reached and the Kuparuk was found to not be hydrocarbon bearing. It was decided to plug back the existing well bore with cement, and sidetrack to another in board location north-west of the orginal landing location (CD4-301A). The pilot hole will be abandoned with an abandonment plug (to cover the Nanuq) and one kick off plug (see sundry application submitted 12-19-07 for more information). A mud gap will be left between the kick off plug and the abandonment plug. The well, CD4-301A, will be kicked off at approximately 10,000' MD and be re-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. 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 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. The 8-3/4" plugged back hole will maintain the name CD4-301 and once re-drilled the new sidetracked hole will become CD4-301A with an APi extension -01.

Circulate tubing to diesel and install freeze protection in the annulus. 13. Drop ball and rod, set packer and test tubing and annulus to 3500 psi / 30 mins. 14. Shear valve in the gas lift mandrel. 15. Set BPV and secure well. Move rig off. Post rig well work will include pulling the ball and rod assembly, and GLV change out. ORIGINAL 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 CD4-301A 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. ' 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 Pumpina Operations: Incidental fluids developed from drilling operations on well CD4-301A will be injected into apermitted annulus on CD4 pad or the class 2 disposal well on CD1 pad. The CD4-301A 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 CD4-301A 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) " (2387') + 1,500 psi = 2989 psi Pore Pressure = 1,086 psi Therefore Differential = 2989 -1086 = 1903 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 ORIGINAL Cementing Program: 7" Intermediate Casing run to 15281' MD / 6912' TVD Cement from 15281' MD to 12365 +/-' MD (minimum 500' MD above top of Nanuq reservoir) with Class G + adds @ 15.8 PPG.

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.

Test BOP's to 5000 psi. 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. Drilling below conductor casing (16") ASP = [(FG x 0.052) - 0.1 ] D =[(10.9x0.052)-0.1]x 114=53 psi OR ASP =FPP - (0.1 x D) = 1080 - (0.1 x 2387') = 841 psi 2. Drilling below surface casing (9 5/8") ASP = [(FG x 0.052) - 0.1 ] D _ [(14.5 x 0.052) - 0.1] x 2387 = 1561 psi OR ASP =FPP - (0.1 x D) = 3128 - (0.1 x 6912') = 2437 psi 3.

I. Supervisor I~~~~~ ~~Z4~~~ FROM: Bob Noble Petroleum Inspector SUBJECT: Wellbore Plug CD4-301 A Conoco Phillips Alaska Colville River Unit PTD #207-1740 Jan 30th, 2007: I witnessed the verification of plug placement in C.P.A.I.'s Alpine development well, CD4-301A. I traveled to Conoco Phillips's Alpine field, Colville River Unit, CD4-301 A, Doyon rig #19, to witness a tag on a cement plug. This plug was to isolate the well from the stuck bottom hole assembly containing a nuclear source. It was reported to me by Nina Woods (C.P.A.I. drilling engineer) that they had received authorization from the N.R.C. and verbal authorization from the A.O.G.C.C. to proceed with the abandonment. - ~ ~~ ~© ~ ~Q~v~ ~ ~,,~~. ~ J ,~~c~, On arrival I met with Larry Hill, Conoco Phillips rep, who reported that 54` bb~s (304sk) of 17ppg, Class G cement had already been pumped and laid in on top of the fish. I observed the rig run in drillpipe with aopen-ended mule shoe to 12702ft' where, with pumps running, weight was observed to fall off. The pumps were shut off and a 15K down tag was made at the same spot. By the numbers supplied to me this placed the top of plug 743ft' above top of the fish. TD of well was 15431ft'. Length of fish was 1,872 ft. Top of fish was 13445ft'. Top of cement was 12702ft'. Summary: I witnessed the verification of plug placement in C.P.A.I.'s Alpine development well, CD4-301 A.
