P()C: H 4 ~... t, PlIII.." { ~ , PHILLIPS ALASKA, INC. GRIZZLY #1 ( \ DRilliNG SUMMARY PROSPECTUS The desired goal of Phillips Alaska Inc.'s GRIZZLY 1 was to find oil in economic quantities to justify extending the current oil production infrastructure to this "uplands" area north of the Kuparuk Field. The information acquired while drilling GRIZZLY 1 should prove very useful in the continuing effort to investigate, define and exploit the hydrocarbon potential of the North Slope of Alaska. The PAl GRIZZLY 1 objective was to drill through, and then log, two or more high-potential target sections. The subsurface projections based on 3-D seismic work could be validated, and the new data would apply to newer and increasingly more accurate stratigraphic delineations. Drilling returns would be examined for oil show properties and then producibility verified by wireline logging. The well plan was to drill vertical from surface, kick off at a shallow depth (900':1:), build to a moderate inclination (24.0°+) in a Southwesterly azimuth (255.7°+) and then slowly drop angle in a slightly more Southerly direction to the final target. Included zones of interest were the Grizzly Wedge (Cretaceous), Omaha Sandstone (Cretaceous), Juno/Utah Sandstones (Cretaceous) and the Bryce Sandstones (Cretaceous). The option of taking full cores in one or more potential "pay" zones was included in the well plan. ( BRIEF SUMMARY OF ACTIVITY The drilling rig was Nabors Alaska Drilling #19E. The surface location was 2252' FNL, 1969' FEL, SEC 1, T 4N, R5E, UM. The well was spudded at 115'MD on March 14, 2002, and reached a Total Depth of 8509' (7987.00' TVD) on April 5, 2002'. There were no major problems that caused delays in the drilling of GRIZZLY 1. The main well plan was executed without significant changes and, with the exception of a failed core attempt at 8096', most activity was routine. There were some minor clay/shale sticking problems that caused delays, but with the expectation that certain shale zones would be difficult, the time plan was not exceeded. Unfortunately, as the open hole duration increased, the mobile interbedded shale and volcanic ash in the long middle section of the hole formed bridges in the wellbore, and ultimately prevented the core barrel from going to bottom. The interval from 3960' to 4030' proved to be tight, sticky and ultimately impassable, and the core barrel had to be pulled out of the hole. ( The bridging and sticking problems also became more pronounced after reaching T.O., and eventually limited the wireline logging program to only one successful run. Logging tools were unable, at different times, to get through the large shale-dominated zone from the 9 5/8" casing shoe to roughly 4500'. On a clean up run through this interval the drill string got stuck and had to be jarred out. The Plug and Abandon program was delayed a day by a failure to tag-up on the highest intermediate cement plug. A successful cement plug was set on the second try, and the rest of the program was otherwise routine. [:I EP()C:H 5 ( ( 4LL." { œPHILLIPS ALASKA, INC. GRIZZLY #1 ( '. BRIEF DIRECTIONAL REVIEW GRIZZLY 1 was drilled vertically from surface to the kickoff point at 900'. Hole Inclination Angle was built from 0.08°at 900'MD to 23.14° at 2213'MD 12178.51 'TVD, and then tightly ranged from 21.61 ° to 23.80° until 6604'MD 16231.49' TVD. After formation properties and extended sliding caused an uupward turn" to a maximum of 25.99° at 6795'MD 16405.00' TVD, the inclination angle was forced slightly downward, and then allowed to gradually decrease. The final projected inclination angle was 16.46° at 8509.72'MD 1 7987.00'TVD. ( The planned well path was West-Southwest at a Vertical Section Azimuth of 255.72°. The build portion of well path became a series of long corrections from alternating westerly and southerly positions. At kickoff the first Azimuth was 249.370. During the first combined build of inclination and turn to the west, the direction slid to a maximum westerly Azimuth of 262.04° at 1460'MD 1 1456.28'TVD. After 1460' a directional correction back toward the planned path was initiated. The new more southerly well path "overcorrected" , sliding past a 255.81 ° Azimuth at 2888'MD 1 2802.97'TVD, and reaching a direction of 252.52° at 3365'MD 1 3243.15'TVD'. From 3343' the path was drilled in another gradual westerly correction to 260.51 ° at 4829'MD 1 4587.46'TVD. From 4829' the direction switched southerly again and at a more rapid degree of change, to a maximum southerly direction of 237.67° at 6034'MD 1 5706.80'TVD. After 6034' the well path became a series of short tight faster turning corrections ranging from 245.44° at 6604'MD 1 6231.49'TVD to 237.58° at 8126'MD 1 7622.03'TVD along an average azimuth of 240.5°. The last direction change was westerly to a final projected Azimuth of 244.68° at TD (8509.72'MD 1 7987.00'TVD). LOGGING PROCEDURES Epoch Well Services provided RIGWATCH 2000TM Drilling Monitoring services and DML TM Mudlogging Service. A QGMTM electric motor driven gas trap was used to maximize the agitation of mud returns, enhance the break out of mud gas, and obtain the optimum sampling. Hydrogen Flame Ionization (FID) Hydrocarbon Analyzer and Chromatograph instruments were used to detect and analyze the formation gases, after a mud gas-air mixture was continuously drawn from the gas trap to the logging unit by sample pumps. Wet and Dry cuttings samples were collected at regular 30' intervals and critical 1 0' intervals in zones of interest as directed by PAl's sampling program. Additionally, Gas Bag samples were caught at regular 500' and 200' intervals and at more frequent intervals in zones of interest. ( Daily logs and zip files were produced for the Phillips geologist.

SILTSTONE (3635' - 4590') = Light medium gray to medium gray with very strong light brownish gray secondary hues; (a significant fraction of the very fine sandstone in this interval is gradational to siltstone and vice versa); in general the lighter colored siltstone is often sandier, and the darker colored siltstone is clayier; the siltstone in this interval, though gradational in part with the other lithologies, is not as homogeneous as in the section prior to 3635'; slightly to moderately brittle to firm to sometimes marginally hard; tough to fragile; many silt-sand-clay textural combinations; dominantly silty to microabrasive texture; after 3630' there is a very common micromicaceous texture in addition to the silty-abrasive; earthy to microsparkly lustre; many sample pieces display microthin interbedding of two or more lithologies; many obvious indicators of thin bedding; most of the siltstone is shaly, especially the micromicaceous variety; note that from 3635' to 4075' the siltstone and the interbedded shale and claystone are slightly lighter than medium gray overall, but after 4075' the (:I F.P()C: H 19 ( ( ( ( i ~~ ~PHILLIPS ALASKA, INC.

SHALE I CLAYSTONE (3635' - 4590') = General notes on all mudrock, sandstone, and mineral features in this interval; two major shale types: argillaceous and silty, with the silty being much more abundant; darker gray shale and claystone are virtually the same rock with minor differences in fissility; locally all the constituent lithologies look more like single variable rock type, than a group of different rocks; much of the claystone-shale and some of the "finer" siltstone appears to have been silica and/or calcite replaced to varying degrees, and the and the "exposed" ends of microcrystals have produced a common to locally abundant microsucrosic texture; pyrite is consistently present in rare to trace amounts, and locally is a variety of forms, including massive, crystalline, and aggregated (euhedral) microcrystals; after 4080': traces of inoceramus are present, the lithics fraction of the sandstone is much less diverse, and siltstone is dominated by medium dark gray to medium gray primary colors with faint to strong brownish gray and olive gray secondary hues.

I. Supervisor Sundav. April 21.2002: I traveled to Phillips Grizzly #1 exploratory location to inspect the casing cut off and abandonment of this well. All casing strings had been cut off at approximately 5' below Pad level and all were found to be full of cement. A 1/4"thick marker plate was welded to the 16" conductor with the required information bead welded to it.

I witnessed the BOT cement retainer set 75' from 9 5/8" casing shoe. I witnessed a volume of cement pumped thru the retainer to cover 100' of open hole below the casing shoe & the cased hole to the cement retainer. The cement was pumped by Schlumberger pumping services, displaced by Rig Pumps. There was no void or cement fall out during the time it took to swap from Schlumberger to Rig Pumps. The Drilling Foreman elected to un-sting from cement retainer & place a balanced plug to cover cased hole 50' above cement retainer. I witnessed the cement retainer capped wI 50' of cement. I witnessed the cement retainer, 9 5/8" surface casing along wI the liT AM" port collar, tested to 1500 psi. For 30 minutes. Summary: I witnessed the successful segregation of the cased & uncased portions of the Grizzly #1 wellbore to prevent vertical movement of fluid within the weHbore.

Nabors 19E personnel were not ready to tag the plug at the scheduled time and an additional 6 hrs. elapsed while the cement plug was allowed to harden. A 27/8" mule shoe XO'd to 4" drillpipe was RIH to 5618' MD and circulation was established at a rate of 1.5 BBUmin. Bottoms up was circulated with no indication of cement in the returns. The rig crew continued RIH to +/- 5650' MD where it was determined that the depth of the top of the cement plug was insufficient to cover the hydrocarbon zones per regulation 20 MC 25.112 (1)(A). Due to a conflict with a previously scheduled inspection I was not able to remain on location to witness the eventual tag of the TOC. I informed PAl representative Granville Rizek that additional cement would be required to properly abandon this zone, and he agreed to perform the task and notify the AOGCC inspector on duty when completed.

You are presently drilling ahead looking for your objective which is likely a little deeper than planned. It has not been the practice of the AOGCC to force a trip to allow a test to be conducted. Based on your forward plans, you have approval to delay the test until you are next out of the hole. Please keep us informed regarding how operations proceed. A BOP test must be conducted before you next trip in the hole. With regard to drilling deeper, as discussed new paperwork will be needed only if you drill more than 500' beyond the presently permitted TO. Good luck.

Overstreet Exploration Drilling Supervisors 659-7881 [Fwd: G~1y mud disposal] ( J: \ Subject: [Fwd: Grizzly mud disposal] Date: Wed, 13 Mar 2002 16:38:22 -0900 From: Tom Maunder <tom_maunder@admin.state.ak.us> To: Cammy Oechsli <Cammy_Oechsli@admin.state.ak.us>, Daniel T Seamount JR <dan_seamount@admin.state.ak.us>, Julie Heusser <julie_heusser@admin.state.ak.us> All, I have received the attached request from Tom Brassfield regarding an exception to 20 AAC 25.080 (d) (4) which, without approval, does not allow disposal of drilling waste into the annulus of a well not located on the same drill site. In this case, Phillips requests to dispose of liquid drilling waste from their Grizzly exploration well into an approved annulus on the Meltwater pad. This request is for the liquid waste only, any cuttings are planned to be hauled to G&I at DS 4. G&I is nearly 100 miles one way from Grizzly. The Meltwater site is located some 32 miles north of Grizzly and is the closest developed site. PPCo has permitted several wells at Meltwater for annular disposal for the drilling wastes developed at that site. PPCo is requesting the exception to .080 (d) (4) in order to help reduce the number of trucks necessary to move the drilling waste and thereby reduce additional traffic on what is going to become a very congested stretch of road between Meltwater and the Kuparuk field. I support Phillips' request. Subsurface disposal is acknowledged as the most environmentally acceptable method to handle drilling waste. Granting Phillips. request will help mitigate the traffic between Meltwater and Kuparuk field which differentially should enhance the overall safety there. Annular disposal has been approved in several of the Meltwater wetls and no problems have been reported. Phillips acknowledges that they are not seeking to have the regulatory proscribed volume per annulus (35,000 bbls) increased. Granting this request should not impair the ability of Phillips to dispose of the drilling waste generated at Meltwater nor result in waste. Also, no USDWs have been identified in the Meltwater area. I request your concurrence with my recommendation.

Cuttings from Grizzly will be placed in the cuttings pit on location (Standard Exploration practice) and taken to Prudhoe Bay Grind & Inject facility at DS4 at the end of the well. The haul is about 1/2 of that required to 1 R pad, and as referenced below decreases the traffic density north of 2P pad, especially when the 870 gravel haulers start their gravel work 3/15 between F pit and 2P Pad.

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 has not been requested as part of the Permit to Drill application for Grizzly #1. 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 surface interval (from base of conductor to surface casing shoe) must be logged with GR/Resistivityand Sonic or NeutronJDensity. Ii ( { Permit No: 202-040 March 4, 2002 Page 2 of 2 Blowout prevention equipment (BOPE) must be tested in accordance with 20 MC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test perfonned 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.

Drillina Area Risks: Shallow Hazards: See attached explanation Drilling Risks: Examination of the offset wells, Tulaga #1, Wolfbtn 32-7-8, Meltwater #1, Ekvik #1 (See attached mud weight versus depth graphs for these wells), reveal no subsurface hazards such as abnormal pressure or lost circulation zones. A Seismic Analysis was performed for the Grizzly # 1 well and Pore Pressure/Fracture Gradient Curves derived. Again, no indications of abnormal pressure or weak formations were seen particularly at shallow depths. The mud weights planned for Grizzly # 1 are conservatively based on those used during drilling of the offsets. Prudent and precautionary drilling/tripping techniques will be emphasized while drilling this well with specific regards to potential shallow gas hazards. Annular Pumpina Operations: Incidental fluids developed from drilling operations will be hauled to the nearest permitted Class II disposal well. (Note that cement rinseate will not be injected down the dedicated disposal well but will be recycled or held for an open annulus.) The Grizzly #1 surface/intermediate casing annulus will be filled with diesel after setting intermediate 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. PAl may request approval to inject or dispose of fluids in the Grizzly # 1 9-5/8" x 7" annulus at a later date. This request would be made after sufficient data is available to meet the requirements of AOGCC's 20 AAC 25.080. ORIGINAL IV. .~. Phillips Alaska, Inc.

Ten-foot (10') wet and dry samples, or continuous, collected across the target intervals. Flow Testing Currently, Phillips plans to complete and test the Grizzly #1 well. Flow testing and pressure build-up tests will be used to determine formation properties and estimate the commerciality of this exploratory well. A reservoir stimulation may be performed in the form of an acid or frac treatment. The flow period will be determined on-site in response to analysis of initial II. III. ORIGINAl ( Phillips Alaska, Inc. ( flow period, PBU and fluid properties. The well will be flowed to temporary surface production facilities consisting of gas separation and fluid storage tanks. Produced fluids will either be trucked to an existing production facility or reinjected into the formation following completion of the flow testing operations. Additional prospective intervals may be tested as described above or may be commingled with the previously tested intervals. If commingling is chosen, production logging will be performed during the flow test to determine the productivity of the individual zones.

ORIGINAL 'It ( ( (' PHilliPS PETROLEUM COMPANY To: Martin Olsen Tom Brassfield A TO-1388 A TO-1550 From: Herbert Swan ATO-1370 Subject: Pre-Drill Seismic Pore Pressure Prediction for Kuparuk Uplands Proposed Wells Grizzly #1, #2, #3, Heavenly #1, #2 and Supercub #1 CONFIDENTIAL Date: November 12, 2001 ( Summary Seismic velocity data was used to predict pore pressures likely to be encountered in six proposed well locations. A local compaction trend and a local pressure calibration model were established using control from the only four wells in the vicinity: Tulaga #1, Wolfbtn #32-7-8, Meltwater #1 and Ekvik #1. The compaction trend and calibration model established from these wells were applied to velocities from the Grizzly 30 seismic survey to predict pore pressures. These predictions show no apparent shallow hazards or large pressure anomalies at the proposed wells located within the 3D survey. One proposed well (Grizzly 3 in the Grizzly "C" block) does not lie within this 30 survey. For this well, a 20 seismic line was used instead. This 20 line also shows no apparent shallow hazards or large pressure buildups at the Grizzly 3 location which exceed 12 Ibs/gal. However a large potential pressure buildup close to the proposed location is indicated (Figure 14). This apparent pressure buildup could be the result of a local lithology change, a missed velocity pick, or the poorer quality of the 20 seismic data, but it warrants further analysis before this location is drilled. Pressure Calibration from Well Logs: ( Phillip's PPFG software (developed by ARCO Exploration and Production Technology) was used to calculate the predicted pore pressures. ORIGINAL ~ ~. 1\ (' Four existing wells in the Kuparuk Uplands area were used to establish both a local normal compaction trend line and a pressure calibration model. These wells were: Ekvik 1, Meltwater 1, Wolfbtn 32-7-8 and Tulaga 1. It was found that a single normal compaction trend would not optimally fit all four wells. However, a single compaction trend slope, and a single pressure calibration, will lead to conservative estimates of pore pressure, which are valid for all the proposed well locations. The Wolfbtn 32-7-8 well, in the northeast corner of the survey, yielded an optimal shale compaction trend line having a 136 us/ft intercept and a -2.97 x 10-5 slope. (See Fig 1.) A pressure calibration model was established by comparing transit time differences (M T) to mud weights. This model calculates pressure gradients (PP) using the equation PP = C2*ååT**2 + C1*MT + CO Where C2 = 0.00154, C1 = .0365, CO = 8.94 ( This same calibration proved to be valid in the rest of the wells. When the deviations from the Wolfbtn compaction curve are combined with the pressure calibration model, a slight overpressure (no more than 11 Ibs/gal) was obtained. This was in good agreement with the recorded mud log, shown in the right half of Figure 1. Although this model was originally derived for use in Offshore Texas, it is thus validated for use in the Kuparuk Uplands. The Tulaga 1 well, located in the southwest corner of the survey, yielded a different shale compaction trend (Figure 3) than Wolfbtn 32-7-8. This trend had an intercept of 129.9 us/ft and a slope of -3.8 x 10-5, This trend accurately predicted the top of geopressure at 6200 ft subsea, and the moderate pressures of 13 Ibs/gal seen at the target depth. The erroneously high pressure predictions of 15 Ibs/gal at 10800 ft subsea were due to the pebble shale (HRZ), an organic-rich condensed section prevelant in this area. The erroneously high pressure predictions of 17.5 Ibs/gal at the bottom of the well are due to bad sonic log readings, and should be ignored. The Meltwater 1 well, located in the northcentral part of the survey, yielded a shale compaction trend similar to the Tulaga 1 well, as shown in Figure 2. The trend which is optimal for Tulaga is also adequate for Meltwater. The Ekvik 1 well, located in the center of the survey, shows the same compaction trend slope as Tulaga, namely -3.8 x 10-5. However, both the log data (Figure 4) and the seismic data (Figure 5) indicate that the intercept should be shifted to 136 us/ft. Such small local shifts are not uncommon in this area. The seismic data indicates that the top of geopressure is at 6000 ft subsea, which was significantly below the bottom of the well. ( In summary, the Tulaga compaction trend yields the most conservative (Le., highest) estimates of pore pressure. For this reason, I chose it for the geohazards study of all the proposed wells except Supercub. Because of its close proximity to the Ekvik well, I chose the Ekvik compaction curve to calibrate Supercub. ORIGINAL ~ " ( (" Seismic Processing: The accuracy of seismic geopressure analysis depends critically on the accuracy of the input velocity field. The velocities used here were generated using Phillips' AVEL program, an automated high-resolution velocity analysis program developed by ARCa Exploration and Production Technology. This process produces a very accurate velocity field defined at every sample in time and laterally along each seismic line. The output RMS velocities were smoothed over 9 CDPs to minimize instabilities in the velocity field that might result from noise, lack of signal or variations in CDP fold. Seismic Pore Pressure Prediction: Pressure gradients were predicted at each well location from 3D seismic velocities. This report includes displays of pressure gradient predictions on all 3D inlines, both in time and in depth. Inlines are plotted from west (left) to east (right). Crosslines are plotted from south (left) to north (right). The 2D seismic line runs south to north.

Conclusions: ( 1. Moderate pressure buildups are expected in the Heavenly wells, starting at a depth of around 8000 ft subsea. These buildups are not expected to exceed 11 Ibs/gal. 2. Normal hydrostatic pressure (9 Ibs/gal) are expected along the entire length of the Grizzly 1, Grizzly 2 and Supercub wells, due to their relatively shallow penetrations. 3. A suspicious apparent pressure buildup is seen in the vicinity of the Grizzly 3 well at a depth of 5000 ft. The very high pressure of 19+ Ibs/gal that is indicated seismically is probably the result of a bad initial velocity pick. However, a more moderate pressure buildup of 12 Ibs/gal is seen along a horizon that intersects the borehole path (Figures 14, 15). This horizon-consistent effect could not be caused by a single bad velocity pick. Another explanation for this anomaly is caused by a lithology change. For example, it is known that organic-rich clays, such as the pebble shale, have abnormally low velocities, and hence appear seismically to have high local pore pressures, when in fact they do not. 4. The base of permafrost appears as a dark blue band between 1000-2000 ft depth. The apparent mud weights of 10-10.5 Ibs/gal are caused by this transition zone. 5. It is always possible for methane hydrates to be found in or around the base of permafrost transition zone. These hydrates do not exhibit acoustic properties, which are sufficiently different from permafrost itself to be detected seismically. Nevertheless, they can pose a significant drilling risk if proper safeguards are not in place. Feel free to call me if you have any further questions about this work.

I.; " ~, There is a growing trend toward not proposing any porosity logs in the surface hole section in exploratory wells. These logs are valuable sources of information concerning presence / absence of hydrates and for determining salinity distribution in potential shallow aquifers. Grizzly is a remote exploratory well that is 7 miles away from the closest exploratory well and 9 miles away from the next closest exploratory well. I recommend requiring running GR, resistivity and either sonic or neutron/density logs over the surface hole interval in Grizzly 1. ~~: "2 - -z- {p ~ D 2.---" .."='t d c.aY\ ~ dMM z/ ZJo/O2, ( ;( (PHI~LlPS\ PHilLIPS Alaska, Inc. ~ A Subsidiary of PHILLIPS PETROLEUM COMPANY Post Office Box 100360 Anchorage, Alaska 99510-0360 Mark Chambers Phone: (907)265-1319 Fax: (907) 265-1336 Email: mchambe2@ppco.com January 23, 2002 fR'" E "~"~\\, r"",""-,-",rj;'\) IE' D ~ .~' \~"".. ~' ' , ... ~, '; ,,'_""," , '~",;<,! ;~~"""!~ i , Cammy Oechsli Taylor, Chair Alaska Oil and Gas Conservation Commission 333 West ih Avenue Suite 100 Anchorage, Alaska 99501 (907) 279-1433 /' n C) ", "', C' ('1'-' " ',:~I ..' \,-, ;,i I : )¿ '~,',~1 I'" v (~, " Alaska Oil [; G~~s Cons.

This well will be accessed via ice road originating from the gravel road running between 2N and 2P Pads and drilled using Nabors 19E. The Grizzly #1 is designed to penetrate, evaluate and test the production potential of the objective sands. As indicated in the attachments, the drilling program will entail drilling an 8-1/2" wellbore through the objective with a full LWD logging suite for evaluation. Based upon favorable log data, Phillips plans to run 7" production casing and test post-rig. The proposed casing program will utilize a 9 5/8" surface casing string, a 7" intermediate / production casing string and 3-1/2" tubing. Please find attached information as required by 20 MC 25.005 (a) and (c) for your review. Pertinent information attached to this application includes the following: 1) 2) Form 10-401 Application for Permit to Drill per 20 MC 25.005 (a). Fee of $100 payable to the State of Alaska per 20 MC 25.005 (c) (1). ORIGINAL { { 3) A directional plat showing the surface and bottom hole locations proposed for the well per 20 AAC 25.005 (c) (2). Diagrams and descriptions of the BOP and diverter equipment to be used (Nabors 19E) as required by 20 MC 25.035 (a) (1) and (b) are on file at the AOGCC office. A complete proposed casing and cementing program is attached as per 20 AAC 25.030. A wellbore schematic is also attached visually depicting the proposed well. The drilling fluid program, in addition to the requirements set forth in 20 AAC 25.033 are attached in this APD package. Seismic refraction or reflection analysis as required by 20 MC 25.061(a) are attached in this APD package. 4) 5) 6) 7) 8) PHILLIPS does not anticipate the presence of H2S in the formations to be encountered in this well. However, H2S monitoring equipment will be functioning on the rig as is the standard operating procedure in the Kuparuk River Unit drilling operation. Complete mudlogging operations such as type log generation and sample catching are planned. The following are PHILLIP's designated contacts for reporting responsibilities to the Commission: 1) Completion Report Sharon Allsup-Drake, Drilling Technologist (20 AAC 25.070) 263-4612 2) Geologic Data and Logs Paul Decker, Geologist (20 AAC 25.071) 263-4236 The anticipated spud date for this well is March 01, 2002.
