Presented herein are the results of this study along with a brief description of the requested procedures and tests. In conjunction with the report, the Core Analysis results are supplied in ASCII and Excel formats on an IBM PC compatible floppy diskette. We appreciate this opportunity to be of service and hope these data prove beneficial in the development of this reservoir. DESCRIPTION OF SERVICES Sample Preparation (Dean Stark Analvsisl Samples with sufficient material for analysis were cleaned of drilling mud and trimmed to right cylinders. The samples were then inserted into thin-walled metal jackets and fitted with 120 mesh end-screens. The jackets were seated to the samples, under hydrostatic loading at a pressure determined by Equation 1. Ps = (Ds- 100) 1) Where: Ps = Seating pressure Ds = Sample depth Fluid Extraction and Saturation Determinations (Dean Stark Analysis) All water and'a portion of the contained oil were extracted by Dean Stark methods using toluene as the solvent. Samples were maintained at 230°F in the extractors until .water volumes ceased to increase in the receiving tubes ( a minimum of sixteen hours extraction). Additional hydrocarbon removal was performed in soxhlet extractors using an 80:20 methylene chloride/methanol mix. The extracted samples were placed into a convection oven and dried at 240°F until stable weights were attained, and then cooled to room temperature in a desiccator. Grain Density Determinations 'Sample grain volumes were determined using a Boyle's Law extended range helium porosimeter. Metal jacket and end-screen weight and volume corrections were applied to the jacketed samples. Grain densities were calculated using Equation 2. (~ma I Where: (~ma = Mg = IVg = Porosity Determination Mg (2) Matrix/grain density (g/cc) Grain mass (g) Grain volume (cc) Samples were installed into Hassler holders and a confining pressure of 400 psi was applied. Direct pore volume measurements were performed upon the confined samples utilizing Boyle°s Law double-cell methods. The porosity values were then calculated using Equation 3. Where: ~ = Porosity (%) Vp = Pore volume ('cc) Vg = Grain volume (cc) Fluid Saturation Calculations Oil and water saturations were calculated using Equations 4 and 5.. Sw - (4) (5) Where: So : Oil saturation (%) Mw Sw : Water saturation (%) Vw Mf = Fresh sample mass (g) Md = Dried sample mass (g) Vp = Extracted water (g) = Extracted water (cc) = Oil Density (g/cc) = Pore volume (cc) Permeability to Air Permeability determinations were made on the confined samples following the pore volume measurements. Hassler-type holders were again used for confinement at 400 psi. Permeability values were calculated utilizing Darcy°s Equation for compressible fluids, Equation 6. L' ~o'--;~ 'j ~ (6) Where: Ka = Pa =' vg = AP = p = Qa = L = Vb = Permeability to air (md) Atmospheric pressure Gas viscosity (cp) Differential pressure Mean pressure Flow rate (cc/sec) Length (cm) Bulk volume(cc) Sample Disposition The residual samples will be stored for thirty days pending instructions for' further analysis or permanent storage arrangements.

There have been a number of them this year. You are planning to perform the remainder of the abandonment as designed. There is a little void from the tubing tail to the top of As cement, but your cement volume is designed to fill that void by swap out. you noted in our conversation, it is most important that cement be at surface on the tubing and annulus. You have approval to proceed as planned. Please have your supervisor stay in contact with John Spaulding so that he may witness as desired/able.

This well is accessed via ice read originating near 2L Pad, and drilled using Doyon Rig #141. The attached Sundry and back-up information describes the suspension procedure for the existing wellbore and has been discussed with AOGCC personnel. The most likely scenario will be to complete a final P&A of the Atlas #lA sidetracked wellbore or second sidetrack (if drilled) before the end of the ice season this year. However, there is a remote possibility Phillips may want to save the option of utilizing the surface hole for a sidetrack next year. Whatever the final disposition, we will discuss with AOGCC personnel and submit the appropriate documents. If you have any questions or require any further information, please contact me at 263-4603 or Tom Brassfield at 265-6377. Sincerely, ,, -, .

This will allow them to return for sidetrack or to P&A without a rig. I have confirmed with Tom that both plug will need to be tagged. He plans to follow up with the formal paperwork on Monday.

As the course of action is finally decided, give me a call...cell is 244-1567, home phone is 345-0850. A few thoughts that I have are... 1--If it is decided to run casing and complete, there really isn't any need to contact us. Base your cement design on the meeting held the other day between yourself, Bob Crandall and myself. TOC to be about 5900' md. 2--In either the sidetrack or permanent abandon case, a deep plug and a plug at the casing shoe will be necessary. The TOC for the deep plug should be 5900' as determined in the meeting. Such a plug height would likely require setting the plug in 3 stages. This plug should be tagged. For the plug at the shoe, in the P&A case you would likely use a retainer with cement below and cement above. Setting the retainer gives you a default tag. In the potential sidetrack case you propose to set a balanced plug of some 400 or 500' up into the casing. You would plan to tag this plug. 3--For the surface plug in the sidetrack case you would set a balanced plug about 200-300' and then run tubing above it. In the event the sidetrack did not come about, then it would be possible to complete the abandonment without a rig. I hope this captures our discussion. Good luck however you go.

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. Annular disposal of drilling wastes will not be approved for this well until sufficient data is submitted to ensure that the requirements of 20 AAC 25.080 are met. Annular disposal of drilling waste will be contingent on obtaining a well cementefl~surface casing confirmed by a valid Formation Integrity Test (FIT). Cementing records, FIT data, subsequent LOT data following setting production casing, and any CQLs must be submitted to the Commission on form 10-403 prior to the approval of disposal operations. 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. The blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE tests must be given so that a representative of thc Commission may witness the tests. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. Sincerely, J. M.

This well will be accessed via ice road originating near 2L Pad, drilled using Doyen Rig #141, tested and permanently abandoned prior to spring breakup. The original Atlas #1 PTD package included information required by 20 ACC 25.005 (c). We did not experience any shallow hazards while drilling the surface hole for Atlas #1, nor did we experience any overpressured zones drilling to TD. The nearest offset wells indicate no overpressured intervals or lost circulation zones. There will be no reserve pit for this well. Waste drilling mud will be hauled to a KRU Class II disposal well. If a production casing string is set in this well Phillips requests that Atlas #1 be permitted for annular disposal of fluids occurring as a result of drilling operations, per regulation 20 AAC 25.080. As in the past Phillips would submit a 10-403 Form to the Commission with the appropriate technical information. All cuttings generated will be either stored temporarily on site or hauled to the Prudhoe Bay Field for temporary storage and eventual processing for injection down an approved disposal well. If this well is tested, the produced fluids will either be hauled to Kuparuk for recycling or injection into an appropriate disposal well or the produced fluids will be reinjected into the Atlas #1 wellbore. Please note that Phillips does not anticipate the presence of H2S in the formations to be encountered in this well. However, there will be H=S monitoring equipment operating, as is the usual case while drilling wells in and near the Kuparuk River Field.

Casing Setting Depth Rationale 16"-118' RKB Conductor casing to provide sufficient anchor and fracture gradient for diverter system. 9-5/8"-1976' TVD RKB Surface casing to provide good anchor for BOPE and sufficient fracture gradient and well control while drilling to next casing setting point. COMPLETED 7"-7338' TVD RKB Production casing to cover all open hole and all previously set casing to allow comprehensive testing of the well. This casing will not be set if logs indicate the well is a dry hole. Annular Pumping Operations: Incidental fluids developed from drilling operations will be either injected into the Atlas #lA approved annulus or hauled to the nearest permitted Class II disposal well. The cement rinsate will not be injected down the dedicated disposal well but will be recycled or held for the Atlas #lA open annulus or injected down another Kuparuk well open annulus. The open annulus will be left with a non-freezing fluid during any extended shut down (> 4 hr) in pumping operations, The Atlas #lA surface/production casing -2- Atlas #1 PRESSURE INFORMATION AND CASING DESIGN annulus will be filled with diesel after setting production casing and prior to the drilling rig moving off of the well. If isolation is required per regulations over significant hydrocarbons, then sufficient cement volume will be pumped during the production cement job to cover those formations. We request that Atlas #lA be permitted for annular pumping of fluids (if production casing is set) occurring as a result of drilling operations, per regulation 20 AAC 25.080. 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 has been set in the Cretaceous shales below the base of the West Sak Sands. These 300-500' thick shales are part of the Colville Group and are known to provide vertical barriers to fluid flow. 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) * (1976') + 1,500 psi Max Pressure = 2733 psi · This pressure is conservative, since frictional losses while pumping have not been '. "taken into consideration. The surface and production casing strings exposed to the annular pumping operations have sufficient strength by using the 85% collapse and burst ratings listed in the casing performance properties above. Fluids to be disposed of in the annulus will be limited to drilling wastes associated with drilling a well as defined in 20 AAC 25.080 (h).
