Box 100360 Anchorage, AK 99510-0360 Re: Administrative Abandonment Action Colville River Unit CD4-318 Permit # 205-196 Dear Mr. Alvord, Colville River Unit ("CRU") well CD4-318A (permit #206-113, API # 50-103-20519-O1) will replace CD4-318 (permit #205-196, API # 50-103-20519-00) effective the date that permit 206-113 is approved by the Commission. CRU CD4-318A incorporates an extension to a new bottom hole location from the existing CRU CD4- 318 well bore. This extension, along with the original well bore, will be used for production of hydrocarbons. A review of the well history file for CD4-318 and the proposed operations in CD4-318A indicates administrative abandonment of the originating well bore is appropriate according to current Commission procedures for wells when an additional permitted extension is drilled from an existing well bore. 20 AAC 25.005(a) requires a Permit to Drill for each hole drilled below the conductor unless drilled to straighten the original hole, sidetrack junk, or correct mechanical difficulties. In addition, Commission databases require one permit number and API number for each conductor. Administrative abandonment of the original well bore only eliminates duplication in databases. Information for the original well bore and its replacement will be maintained in their respective files. Please notify other affected personnel in your orgamz n that the well will be correctly identified on subsequent reports and applications submitted to th om ssion. cc: Commission Well History File #205-196 Commission Well History File #206-113 C Memorandum z o S -- /9~ State of Alaska Oil and Gas Conservation Commission To: Colville River Unit Well History File #205-19b July 27, 2006 Colville River Unit Well History File #206-113 Re: Administrative Abandonment Action Caused by Deepening of Existing Wellbore Administratively Abandoned Wellbore: Colville River Unit CD4-318 Permit #205-196 Extension Wellbore: Colville River Unit CD4-318A Permit #206-113 This memo will remain at the front of the subject well files.

Wanted to make sure it didn't get missed. Steve Davies and I looked at the file and it is our assessment that a new permit for CD4-318A needs to be submitted. According to the 407, the well was reported completed and there was cleanup production reported. This is similar to CD2-17 and CD2-17A, although you didn't drill as far. Are your plans to pull the completion and then just go in and drill on or will you be setting some cement or a retainer? If you are just going to drill on, then a sundry won't be necessary. CD4-318 can be administratively abandoned. If there is some "plugging" planned, then a sundry is necessary. The pull completion work can be authorized with the new permit to drill. Call or message with any questions.

I cannot find any emails regarding the matter. Is it you all's intent to pull the "guts and feathers" and then drill on to the original BHL? I looked at the file and a 407 was received on June 7 with the well listed as a completed oil well. I have to do some checking, but since the well has been reported as completed with some production as well, it may be that CP will have to apply for a new drilling permit as CD4-318A.

This well was suspended in January this year due to having hole problems right out of the 7" shoe and losing the cones off our insert bit. Also we were in a hurry to get on the ice road to CD3. We should be moving the rig to CD4-318 early next week. Let me know if there is anything we need to do from here. 1 of 2 7/27/2006 9:12 AM STATE OF ALASKA ALASKA OIL AND GAS CONSERVATION COMMISSION REPORT OF ANNULAR DISPOSAL 1. Operator: 4a.

Please note that any disposal into the surface /production casing annulus of a well approved for annular disposal must comply with the requirements and limitations of 20 AAC 25.080. As provided in AS 31.05.080, within 20 days after written notice of this decision, or such further time as the Commission grants for good cause shown, a person affected by it may file with the Commission an application for rehearing.. A request for rehearing is considered timely if it is received by 4:30 PM on the 23rd day following the date of this letter, or the next working day if the 23rd day falls on a holiday or weekend.

It is intended to begin annular disposal operations on CD4-318 approximately June 3, 2006 or as soon as a permit is available. Please find attached form 10-403RD and other pertinent information as follows: 1. Annular Disposal Transmittal Form 2. Pressure Calculations for Annular Disposal 3. Surface Casing Description 4. Surface Casing Cementing Report & Daily Drilling Report during cement job 5. Casing and Formation Test Integrity Report (LOT at surface casing shoe). 6. Intermediate Casing Description 7. Intermediate Casing Cementing Report & Daily Drilling Report during cement job 8. Formation LOT on 9-5/8" x 7" casing annulus 9. Plan View of Adjacent Wells 10. List of wells on CD2 pad and the lateral distance from the surface casing shoe. 11. Additional information regarding wells within % mile radius at AOGCC: none needed for this permit 12. Copy of previous authorization (CD1 and CD2) for disposal of new product cleanup fluids such as cement rinsate, and mud and brine pit rinse from mixing operations f The initial annular LOT (17.1 ppg) occurred at a lower equivalent mud weight than the casing shoe test (18.2 ppg LOT). Therefore we conclude that waste will not migrate above the confining zone provided we do not inject -- with sustained surface pressures that will cause pressures at the surface shoe to be in excess of the shoe FIT/LOT. If you have any questions or require further information, please contact Vern Johnson at 265-6081; Chip Alvord can also be reached by calling 265-6120.

Alaska, lnc Phillips has made application for annular disposal for the subject well. This document examines the pertinent information for the well and recommends approval of ConocoPhillips' request. --No unusual events were reported while drilling the surface hole of the well. --Surface casing was cemented to surface. No problems were reported. Approximately 203 bbls of cement was circulated to surface. The net cement remaining in the surface hole was 32% XS of the calculated hole volume. --On the initial leak off test, the pressure slope hardly changed to the determined LOT point at 18.2 EMW. Minimal fluid was pumped in. The pressure declined during the observation period to about 17.2 EMW. The initial leak off indicates that the surface casing shoe is well cemented. --No problems are reported drilling the intermediate hole. The 7" casing was run and successfully cemented. Full returns were noted and the casing was reciprocated. Lead and tail slurries were used to place cement above the shallower Nanuq-Nanuq sand. --An infectivity test down 9-5/8" x 7" annulus was conducted. Pressure steadily increases until the break at 17.1 EMW. The pressure declined with additional pumping to 16.6 EMW. During the observation period, the pressure declined to 14.3 EMW. Although about 1 ppg EMW above well CD4-319 on the same pad, the lower EMW of the pump in test indicates that the planned disposal should be conducted at EMWs below that of the shoe integrity. --CPA provided a listing of all surface casing shoes within '/ mile radius of CD4-318. Nanuq 3 and CD4-319 are about 1130' distant at 11 and 2 o'clock respectively from the surface shoe. An examination of the cementing information for these wel~did not reveal any problem that would preclude granting CPA's request for CD4-318. Based on examination of the submitted information, I recommend approval of ConocoPhillips' request for the subject well. ~l ~ ° ~ Tom Maunder, PE Sr. Petroleum Engine r May 24, 2006 G:\common\tommaunder\Well Information\By Subject\Annular Disposal\060524--CD4-318.doc • • Note to File CRU CD4-318 (PTD 2051960) Re: ConocoPhillips' Application for Sundry Approval for Annular Disposal of Drilling Waste on Well CD4-318 Request ConocoPhillips requests approval to dispose of waste drilling fluids by pumping them into the annulus of CD4-318. This annulus extends from the base of 9-5/8" casing at 3,485' MD (2,340' true vertical feet subsea, or TVDss) to the top of 7" casing cement at 11,800' NID (5,930' TVDss). Recommendation Approve annular injection operations in CD4-318 as proposed. Discussion CPAI's application to inject wastes generated by drilling operations into the annulus of CD4-318 was reviewed along with records from offset wells Nanuq 3 (1000' to the north) and Nanuk 2 (1400' to the south). The diagram below illustrates CD4-318 with respect to these offset wells. North Nanuq 3 CD4-318 Nanuk 2 South CRU CD4-318 ~ ~ May 25, 2006 Note to File Page 2 of 2 Various reports from the operator place permafrost thickness between 800' and 1600' thick in this area. My estimate is 1350'. According to the findings and conclusions of Area Injection Orders 18, 18A, and 18B, there are no underground sources of drinking water beneath the permafrost in the Colville River Unit area. Examination of well log data from exploratory wells in and near the CD4 drill site conducted for the Nanuq Area Injection Order (AIO 28) confirms that there are no aquifers within the affected area that could serve as underground sources of drinking water. Surface casing shoes in offset wells Nanuk 1, Nanuk 2 and Nanuq 3 were set near the base of a sequence of interbedded siltstone and claystone at 1750', 2010' and 1740' TVDss, respectively. The surface casing shoe of CD4-3181ies within a thick claystone interval at about 2340' TVDss. The annulus that will be used for disposal of drilling wastes extends from the surface casing shoe to the top of cement for the 7-inch casing string, which is estimated to be at about 5930' TVDss. Immediately beneath the CD4-318 surface casing shoe is a thick sequence of siltstone, claystone and shale with scattered, thin layers of sandy siltstone and silty sandstone that will be receptors for the injected waste fluids. Upper confinement will be provided by about 140 true vertical feet of claystone and siltstone. Lower confinement will be provided by three intervals of claystone, shale and siltstone that have an aggregate thickness of about 180 true vertical feet. Conclusions The 9-5/8-inch casing shoe is set in a thick, competent claystone interval. Upper and lower confining layers are sufficiently thick to ensure injected materials stay within the target interval. There are no USDWs in this area. Based on examination of the submitted information and well records for Nanuk 2 and Nanuq 3, I recommend approval of annular pumping of drilling waste fluids into the annulus of CD4-318.

Oonnrrtissiart Dear Sir or Madam: An~horag~ ConocoPhillips Alaska, Inc. hereby applies for a Permit to Drill an onshore producer well from the Nanuq CD4 drilling pad. The intended spud date for this well is 12/17/2005. It is intended that Doyon Rig 19 be used to drill the well. The pilot hole well, CD4-318PB1 will be drilled through the Nanuq sand and Kuparuk sand at +/-65° inclination for logging and evaluation purposes. A cement plug will be pumped from TD to 450' above the top of the Kuparuk reservoir. It is requested that the tag of the cement above the Kuparuk sand be waivered, since the planned TOC is significantly above the Kuparuk sand and an upper plug above.' A -"~ ~'~~5"~ second cement plug will be pumped from 200+ MD feet below the nanuq formation to 100' above the top boild'~ of the Nanuq formation. A third cement plug will be pumped as a kickoff plug to 11695', 500' above the Nanuq formation. The well CD4-318 will then be drilled off the 3"d cement plug at approximately 11800' MD and landed in the Kuparuk sand horizontally. After setting 7" intermediate casing, the horizontal section will be .drilled and the well completed as a slotted liner producer. The horizontal section will be drilled with mineral oil based mud. At the end of the ~ rig work program, the well will be flowed back for 5 - 15 days to mitigate reservoir damage. The well will then be closed in awaiting completion of well work and facilities construction that will allow the well to begin production fourth quarter 2006. ~ ~~ ~ ~~~~~ ~~~~ A waiver for the diverter is requested. This will be the third well on the Nanuq pad and there has been no indication of gas or shallow gas hydrates. ~ ~~~~~~,~~~,~ ~~t~\oc-e~~-c~ vJctly Please find attached the information required by 20 ACC 25.005 (a) and (c) for your .review, Pertinent information attached to this application inc{udes the following: 1.

C7 Well Proximity Risks: • Directional drilling /collision avoidance information as required by 20 ACC 25.050 (b) is provided in following attachments. CD4-319 is the closest well. Well separation is 21.29 @ 275' MD. Drilling Area Risks: There are no high-risk events (e.g. over-pressures zones) anticipated. Lost circulation: Faulting within the Kuparuk 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. 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 CD4-318 will be injected into a permitted annulus on CD4 pad or the class 2 disposal well on CD1 pad. The CD4-318 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 Nanuq reservoir and there will be 500' of cement fill above the top of the Nanuq as per regulations. Upon completion of CD4-318 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)'` (2600') + 1,500 psi = 3681 psi Pore Pressure = 1,082 psi Therefore Differential = 3681 - 1082 = 2599.5 psi. The internal casing pressure is conservative, since frictional losses while pumpincl 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 fallowing 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 psii 2.992 psi 7" 26 L-80 3 BTC-Mod 5,410 psi 4,599 psi 7,240 psii 6,154 psi DRILLING FLUID PROGRAM ORIGINAL • • SPUD to 9-5/8"surface casing oint -12 %4n Intermediate hole to 7" casing point - 8 3/4" Production Hole Section - 6 1 /8" Density 8.8 - 9.6 ppg ~ 9.6 - 9.8 pp9 ~ 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. 64/36 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 64/36 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.

I have attached them so you will have them. Sorry about not getting them over initially. And this well is going to be drilled with Flo-pro not MOBM. This was incorrect in the permit. Hope you had a great Thanksgiving.

I have attached them so you will have them. Sorry about not getting them over :initially. And this well is going to be drilled with Flo-pro not MOBM. This was incorrect in the permit.
