I've had a public data request for Clover A, PTD 200-007, sidewall core analyses and a digital image of the GR/Res log run by Sperry-Sun. I've checked the well history file, both paper and electronic, and have not found any core analyses,though I did locate core descriptions. The analyses were requested in 2002 but were not supplied and the person on this end did not follow up again. If ConocoPhillips has a digital image available of the GR/Res it would be much appreciated. If not, I will suggest the requestor have the paper log scanned. Thanks so much for your help with this.

Based on your presentation to the Division'on May 8, 2002, I extend the confidentiality time period for the data, reports, and information generated from four of the seven wells listed in Attachment A to your letter.

No future extensions will be granted for these wells, The information generated from the other three wells---Rendezvous 2, Lookout 1, arid Moose's Tooth C--does not become public under AS 31.05,035 until the middle of next year, so I am not extending the confidentiality time period for that information at this time, This confidentiality extension for the information from these four wells is through September 3, 2002, 90 days after the Bureau of Land Management's N'PR-A lease sale scheduled for lune 3, 2002.

Mott Vice President oo-oo'7 March 22, 2002 Pat Pourchot, Commissioner State of Alaska Department of Natural Resources Division of Oil and Gas 550 West 7th Ave., Suite 1400 Anchorage, AK 99501-3510 RECEIVED APR 2002 Re: Request for Extension of Confidentiality Alaska Statute 31.05.035 & Regulation 11 AAC 83.153 Phillips Alaska, Inc. ("PAl"), as operator for and on behalf of the working interest owners ("Lessees") of the wells listed in Attachment A hereto ("NPRA Wells"), hereby respectfully requests extended confidentiality for the reports and information generated from the NPR-A Wells and filed with the Alaska Oil and Gas Conservation Commission as required by state law ("Data"). All of the NPR-A Wells are located on federal lands located within the NPR-A. The Lessees make this request for the following reasons: (1) this Data is important to the Lessees in evaluating acreage in future federal oil and gas lease sales in the NPR-A; and (2) the Data for the NPR-A Wells is protected from public disclosure under federal law and state law. First, the Data from the NPR-A Wells contain significant proprietary and sensitive information relating to the valuation of unleased land within the NPR-A. Disclosing the Data to the public would cause financial harm to the Lessees because additional leasing of lands in the NPR-A will probably take place in the future. An EIS is currently underway for the planning of a federal oil and gas lease sale in the western NPR-A. Due to the remoteness of the lands that could be leased in the NPR-A and the restrictiveness of protections already in place for exploration and development of the leased lands within the NPR-A, disclosure of Data to the public about what the future potential for development for the currently leased lands, which Data was obtained at the sole risk and expense of the Lessees, would be detrimental to the Lessees' competitive position in NPR-A. Second, the Data is protected from disclosure under federal law. Federal statute 5 USC 552(b)(9) exempts "geological or geophysical information and data, including maps, concerning wells" from the right of public inspection and disclosure provided in the Freedom of Information Act at 5 USC 552(a). The NPR-A lease terms under which Lessees leased the lands on which the Wells were drilled states as follows: During existence of this lease, information obtained under this section [section 5] shall be closed to inspection by the public in accordance with the Freedom of Information Act (5 U.S.C. 552). Pat Pourchot, Commissioner State of Alaska, DNR March 22, 2002, Page 2 Paragraph 2, Section 5, NPR-A Lease Form, a copy of which is attached hereto as Attachment B. When a record is protected under federal law, it is also protected under Alaska law. Pursuant to AS 40.25.120(a)(4), a record required to be kept confidential by federal law or regulation is not available for public inspection. The focus of the provision for release of well data after two years under AS 31.05.035 appears to be data taken on state lands, not federal lands over which the Department of Natural Resources does not have jurisdiction. Because the Data is protected from disclosure by federal and state law, the commissioner should extend the confidential status of the Data. If you have any questions or require any additional information, please call me or Mr. Jim Winegarner at 265-6914 and we will arrange a meeting to review this request in more detail.

I was accompanied today by Lee Gooding (Phillips environmental tech) and Rick Overstreet (Phillips KRU drilling superintendent). We flew to the location by helicopter and verified proper location by G.P.S. coordinates. Clover A was drilled and abandoned this last winter exploratory season. We attempted a landing and found that the entire area had standing water over it. A landing was impossible so we circled the location 3 times at a Iow altitude for a visual inspection. Other than the mound of clean gravel over the cellar there was no indications of any drilling activity on this location. We flew the ice road path this was clean and seemed well vegetated. I recommend this location be approved for final clearance. SUMMARY: I made a Location clearance inspection on Clover A. No problems were observed.

I met with Peter Ditton P.E. for the Bureau of Land Management for the U.S. Department of the Interior. Regulations & test procedures were discussed. We proceeded with BOP test with no major problems. As the attached AOGCC test report indicates 2 failures were witnessed. The lower Kelly valve & the full opening floor safety valve failed to hold test pressure. These were replaced & tested OK. This was the first time the hydraulic choke had been functioned since the Rig moved out to Clover "A". The super choke panel needed work before the choke would function properly. It was notice that 4" FH HWDP was being utilized in the drilling BHA. I requested that 4" FH floor safety valve be on hand before POOH after drilling open hole.

The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. A weekly status report is required from the time the well is spudded until it is suspended or plugged and abandoned. The report should be a generalized synopsis of the week's activities and is exclusively for the Commission's internal use. All dry ditch sample sets submitted to the Commission must be in no greater than 30' sample intervals from below the permafrost or from where samples are first caught and 10' sample intervals through target zones. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. Sin~, / ~ Robert N. Christenson, P.E.

Clover A well is approximately 15 miles south and west of the Alpine field While the well is being drilled there is no annulus available (Casing design is 2 strings) Fluids incidental to drilling the well will be hauled to a dedicated injection well at Alpine or Kuparuk The decision on which dedicated disposal well to use will be a business decision If the well is cased, it will create an annulus If the well is cased, it will be tested without the rig on location Without the rig on location, additional equipment would be needed to annulus pump Test equipment would also be rigging up on the well In order to use the annulus, the fluids incidental to drilling the well would need to be stored Stored fluid would need to be heated. Currently, our ADEC air permit does not allow for extra heaters/boilers. The Environmental Assessment prepared by the BLM does not address annulus pumping Current plan is to move the rig from Clover to Arco Spark #1, 12 miles further to the west. I hope this addresses the concerns you raised on the telephone, and please don't hesitate to contact me with further questions. Respectfully, James Trantham Sr. Drilling Engineer ARCO Alaska, Inc. 1 of l 2/8/00 8:01 AM ARCO Clover A NPRA Leak Off Test Procedure After cementing casing and nippling up BOPE, RIH to top of cement and pressure test the casing to 2500 psi for 30 minutes and record on chart (AOGCC required casing integrity test). Record the information on the AAI LOT form (you can locate on the drilling web page). Plot Casing Pressure Test (volume vs. pressure and time holding pressure on casing). Verify that the test indicates a linear line and that there is no air entrained in the mud. Repeat Casing pressure test if needed. 2. Drill 20' to 50' of new hole below the casing shoe. Circulate the hole to establish a uniform mud density throughout the system (required for a good FIT or LOT). PU into the shoe. 4. Close the blowout preventer (ram or annular). 5. Pump down the drill stem at 1/4 to 1/2 bpm. , On the LOT form, plot the fluid pumped (volume or strokes) vs. drill pipe pressure until the formation begins to take fluid; at this point the pressure will continue to rise, but at a slower rate. 7. At leak off pump 3 bbls of mud into formation prior to shutting down the pump. . Shut down when the leak-off point is clearly seen and 3 bbls of mud has been pumped into the formation. Record initial shut-in pressure. With the pump shut down monitor, record and report the shut -in pressures for a minimum of 10 minutes or until the shut -in pressure stabilizes. Record time vs. pressure in 1-minute intervals and plot information. Bleed the pressure off and record the fluid volume recovered. Forward the data to the Drilling Engineer in Anchorage. The Drilling Engineer will forward the information to the Agencies.

The West Fish Creek #1 was the only offset well that was evaluated. Eight seismic inlines from the 1999 East 3D survey were also interpreted all of which have proposed well locations associated with them. All eight proposed well locations are normal pressure with no apparent shallow hazard problems. Seismic Processing: The accuracy of Geopressure prediction is highly dependent upon the accuracy of the seismic stacking velocity field that is used as input. This velocity field is generated by picking velocities at every fourth CDP location with an automated high resolution velocity analysis program (UHCI process developed by AEPT). This process produces a very accurate and densely sampled velocity field to cover each CDP location. The RMS velocities that are output have been smoothed over 300 ms vertically and 150 CDPs horizontally to normalize any instability in the velocity field that might result from noise, lack of signal or variations in CDP fold. Pressure Prediction Procedure: ARCO's PPFG software was used to calculate the pore pressures. The compaction trend looked very similar to what had been observed in Tarn and Alpine, giving reason to use the same models for NPRA. 1) A Normal Compaction Trend Line (NCTL) was determined for each seismic line. The slope of this line was 4.0.5 with an intercept of about 150. 2) A comparison was made between the NCTL and the wireline sonic DT (for W. Fish Creek #1) or the Seismic Integrated Travel Time (ITT, for the proposed wells). This difference is AAT. 3) From the Alpine and Tarn study, a Translational Trend model was developed to convert the z~/XT to equivalent mud weight (PP). This equation is: 2 PP = C2 *AAT +C1 *AAT +C0 where C2 = -2.5769 e-04; C1 = .119231; CO = 8.94231 4) The fracture gradient was determined using the Eaton Method where the inputs are the bulk density (used from West Fish Creek #1) and Poisson's Ratio (from a West Cameron model). West Fish Creek #1 Figure #1 is the pore pressure calculation for this well. On the left is the wireline sonic DT (black curve) with the NCTL (red line). On the right is the pore pressure calculation (blue curve), actual mud weight (green curve), fracture gradient (red curve) and the overburden gradient (black curve). Labeled on the figure is the casing sizes, areas of hole problems, formation tops and areas of lithology changes. From this plot it appears that the models from Tarn and Alpine are similar to NPRA. No leak off data was available to validate the fracture gradient model. <,~,\,,~ ~- ~X',~ Seismic Pore Pressure Predictions (No Indication of Shallow Hazard) The following figures are the pore pressure predictions across the evaluated seismic lines in depth with an overlay of the seismic migration lines. Figure Number Seismic Line Well Name 6 49240 Clover "A' The warmer the colors the higher the predicted mud weight (pore pressure). Based on the West Fish Creak #1, a kerogen shale is located at about 8,800'. This kerogen zone is about 500' thick and appears as an increase in pressure but is actually a lithology effect. Another lithology effect is the silt zone at about 10,000'. The NCTL is based on shales with some silt. The velocity through silts is slower than the shales giving a false increase in pressure. The followh~g figures are the pore pressure predictions across the evaluated seismic lines in time with an overlay of the seismic migration lines. Figure Number Seismic Line Well Name 7 49240 Clover "A' Pore Pressure Prediction at Each Well Location The following figures are the pore pressure prediction for each proposed well location. On the left side of the figure is the seismic Integrated Travel Time (ITT, black curve) with the NCTL (red line). The right side of the figure is the pore pressure prediction (blue curve), fracture gradient (red curve) and the overburden gradient (black curve). Figure Number Seismic Line Well Name 23 49240 Clover "A' Conclusions: 1. There are no apparent shallow hazards for any of the proposed well locations. 2) The West Fish Creek #1 shows that the pore pressure model used in Tarn and Alpine fields appear to work in NPRA. 3) The slope and intercept for the Normal Compaction Trend Line from the Alpine and Tarn study is the same as this NPRA study. 4) There are some lithological effects due to kerogen and silts that give an indication of an increase in pore pressure between 8,000' and 10,000'. The predicted mud weights will range between 10.5 to 11.0 ppg.

The estimated spud date for the well is February 15th. As noted in the General Drilling Procedure, the intent is to drill through the objective and if necessary, the well may be twinned to obtain core. We are applying to permit a pilot hole and twinned wellbore for core if quality reservoir is present. Please note that offset wells show no indication of H2S. However, monitoring equipment will be operational on the fig. Also, from analyzing offset wells and shallow hazards there are no indications that shallow gas will be encountered. After more thorough review of geologic information, the surface casing setting depth has been changed from the original application of 3000' to 3500'. This will allow us to find more competent formation which will increase the casing shoe integrity. This well is located on Federal Lands and will also be under the jurisdiction of BLM. Any coordination with the BLM on inspections would be appreciated because of limited bed space at'the remote campsite. Please hold information on this well confidential. If you have any questions regarding this matter, please contact me at 263.4603 or James Trantham at 265.6434.
