Sampling covered the interval 110 to 7502 feet total depth. This work was done as part of M.C.I. Job Number 98-108. Procedures Standard techniques were used to process the material. All samples were boiled in Quaternary-O and washed over 20 and 200 mesh screens. Frequency symbols correspond to the following numerical values: very rare (1), rare (2 - 4), frequent (5 - 25), common (26 - 100), abundant (101 - 999) and prolific (1000+). The picked foram slides and residues are reposited at the State of Alaska Geological Materials Center in Eagle River, Alaska. Certain factors such as shelf widths, basin configuration and overall basin depths associated with Arctic Mesozoic basins are not completely understood at present. The paleoenvironments presented in this report reflect relative basinal position only and should not be tied to specific water depths. Generally, neritic corresponds to shelf or deltaic environments, while bathyal corresponds to slope or prodelta environments and bathyal (starved basin) corresponds to distal (far from the source) deposition. As an example, prodelta deposits could represent deposition as shallow as middle neritic or as deep as bathyal (slope) depending on the delta type and shelf width. With a narrow shelf, a fiver-dominated deltaic system could build across the shelf and the prodelta deposits would be in a bathyal (slope) depth. A tide-dominated deltaic system associated with a wide shelf could result in middle neritic prodelta deposition. Format A listing of the age, environment, fauna and occasional lithology comments for each biostratigraphic interval follows. A generalized summary of the well is presented in the Conclusions section at the end of the Foraminifera Report. A Foraminifera Distribution Chart (Figure F-I) and a High Resolution Biostratigraphy Plot (Figure B- 1) containing foram diversity/abundance plots, a cumulative faunal plot and paleoenvironmental plot(s) are in pockets at the back of this report. 10 RESULTS 110-1010' Age, Environment.

(M.C.I.) conducted palynological analyses on a total of 107 samples from the ARCO Alaska Bergschrund No. 1 well. The samples consisted of ditch cutting composites between 110 feet and the total depth of 7502 feet. Procedures The samples were processed with standard palynologic techniques using hydrochloric acid, hydrofluoric acid and nitric acid treatments. The resultant kerogen residues were further concentrated by heavy liquid separation, sonification and a sieving/panning technique. Permanent slide mounts were made of the residues. Two square coverslips are placed on each sample slide. One square has the greater than 20 micron fraction and the second square contains the 10-20 micron fraction. As each sample was examined, an estimate of abundance for each palynomorph taxon was recorded in a ~microcomputer. These data form the basic elements of the species distribution chart. Based on the palynomorph assemblages observed, an age and generalized environment of deposition were interpreted for each palynostratigraphic subdivision. The environments, as interpreted from the palynological preparations, are simply categorized as nonmarine, marginal marine or marine. The categories are based on the absence or presence and diversity of microplankton. .Report Format The following Results section gives the age, environment of deposition and significant palynomorphs for each palynological subdivision. This is an expansion of the brief Summary at the beginning of the report. After the Results, some generalized interpretations are outlined in the Conclusions section. 22 A Palynomorph Distribution Chart (Figure P-l) is located in a pocket. This chart records the occurrence and abundance of individual taxa in each sample. Included on this chart are the diversity and abundance curves for spore-pollen and microplankton cysts. High Resolution Biostratigraphy Plots - Foraminifera/Palynomorphs (Figure B- 1) are also provided. Additional palynology parameters are given in the form of a cumulative plot that illustrates the relative abundance of nonmarine, marine and miscellaneous palynomorph constituents. 23 RESULTS 110-830' Zone.

Late Cretaceous Maestrichtian P-TI 1 and marginal marine equivalent Marginal Marine The Maestrichtian section is marked by the pollen species AquilapolIenites magnus and Wodehouseia spinata. The dinocyst assemblage increases in numbers. This increase is obvious in the diversity/abundance curves (see Figure P-I). The dinocysts consist mainly of species of Chatangiella. 24 1280-1910' Zorle. Environment. Palyr!.omorphs. Late Cretaceous Campanian P-T12 and marine equivalent Marine The spore-pollen remain dominant, but the dinocysts increase in diversity. The important pollen species in this interval are Aquilapollenites quaddcretae and A. tdalatus. The dinocyst assemblage consists mainly of Chatangiella species, Isabelidinium acuminatum and Laciniadinium biconiculum. Reworked Paleozoic spores occur sparsely throughout the interval. 1910-2630' Age. Zolle. Environment. Palynomorphs. Late Cretaceous Santonian - Campanian P-M14 Marine The spore-pollen fraction is relatively unimportant in this interval and the marine forms become dominant (Figure P- 1). The dinocyst species increase in diversity with the appearance of many forms of Chatangiella of which C. ditissima is a marker for this zone. Other species in the assemblage include Hystdchosphaeddium difficile, Odontochitina o£erculata and Tdthyrodinium sus£ectum. 25 2630-3560' Zone. Environment. Palynomorphs.

Early Cretaceous Middle- Late Albian P-M17 Marine The Albian section is separated by the appearance of the dinocyst marker species Luxadinium pro£atulum, Ovoidinium verrucosum and S£inMinium vestitum. The consistent occurrences of S£inidinium vestitum appear to form a correlative datum in the lower part of this interval. This datum is placed at 6200 feet in this well. The same point was designated at 5910 feet in the Fiord No. 1 well. Throughout this interval many samples reflect a dominance of nonmarine palynomorphs (Figure P-l). Fairly consistent, rare or very rare, occurrences of reworked Carboniferous age Densospores were recorded throughout this interval. 27 6500-6650' Zolle. Early Cretaceous Barremian- Early Albian P-M18a Environment. Marine .Palynomorphs. The nonmarine component is very sparse through this interval and the marine forms begin to be dominant (Figure P-l). The prolific dinocyst assemblage is marked by the increased abundance of Oligosphaeridium complex, and by the appearance of Fromea amphora, Gardodinium deflandrei, Micrhystridium sp.

Early Cretaceous Hauterivian P-M19 Marine The spore-pollen component remains relatively unimportant contrasted to the dinocyst abundances. The Hauterivian interval typically contains a very diverse dinocyst assemblage. This assemblage includes the species Florentinia cooksoniae, Gardodinium trabeculosum, Imbatodinium micro£odum, Oligos£haeridium complex (thick-wall), ProtoelIipsodinium spinigerum, Pseudoceratium nudum, Sentusidinium rioultii and Tubotuberella uncinatum. Within this interval, below 6700 feet, reworked Mississippian spores begin to appear more consistently, although they remain relatively rare. 29 6830-6950' A~e. Zone.

Various species of the spore TriIobosporites begin their appearance. The ditch samples continue to recover many forms from the interval above. The important species recorded from this interval are Gochteodinia villosa and Tubotuberella apatela. The reworked spores (Mississippian age) begin to increase in consistency and abundance, and continue into the Oxfordian strata below. 30 6950-7502'T.D. Zone. Environment. Palynomorphs. Discussion. Late Jurassic Oxfordian P-M22 Marine The Oxfordian interval is marked by a distinct dinocyst assemblage. This assemblage includes Chytroeisphaeridia pericompsa, C. '~errucosa", Endoscrinium galetitum, Gonyaulacysta cladophora and Nannoceratopsis pellucida. The dinocysts exhibit an increase in relative abundances in the lower part of this interval. The reworked Mississippian spores continue and become quite common in the upper part of this interval. The Oxfordian marker species Nannoceratopsis pellucida tops at 7010 feet. This leaves open the possibility that the top 60 feet of this Late Jurassic interval could be as young as Kimmeridgian. The Chytroeisphaeridia Yerrucosa" datum occurs at 7310 feet. This datum, which is usually associated with the abundant occurrences of Chytroeisphaeridia peticompsa, forms a correlative horizon within the Oxfordian in many of the wells in the Colville Delta region. 31 .CONCLUSIONS Palynological analysis of the ARCO Alaska Bergschrund No. 1 well provides the following generalized palynostratigraphic succession: [] Marginal marine Paleocene strata occur from 110 feet to 830 feet. Marginal marine and marine strata of Campanian and Maestrichtian age occur between 830 feet and 1910 feet. Marine Santonian to Campanian age strata occur between 1910 feet and 2630 feet. Marine strata of Turonian to Coniacian age occur from 2630 feet to 3560 feet. Marine strata of possible Cenomanian age are identified from 3560 feet to 3830 feet. Marine strata of Middle to Late Albian age are present from 3830 feet to 6500 feet. Marine Barrernian to Early Albian age strata are identified between 6500 feet and 6650 feet. A very small percentage of the organic recovery is land-derived material. Marine Hauterivian age strata occur from 6650 feet to 6830 feet. The very high percentage of marine-derived organic material persists in this interval. Marine probable Valanginian age strata are interpreted to be present between 6830 feet and 6950 feet. A marked increase in land-derived organics begins in this interval and continues through much of the Jurassic section below. Marine Late Jurassic (Oxfordian) strata occur between 6950 feet and the total depth of 7502 feet, although the top 60 feet of this interval may be as young as Kimmeridgian. Most of the section contains a large percentage of reworked Mississippian spores. 32 TONY KNOll'LES, GO FERNOR DEPT.

Landt District Landman ARCO Alaska Inc. P. O. Box 100360 Anchorage, Alaska 99510-0360 Subject: Request for extended confidentiality Bergschrund No. I and Fiord No. 2 In your January, 31 1996 letters you requested extended confidentiality for Bergschrund No. 1 and Fiord No. 2 under the authority of 11AAC 83.153. Under this regulation: The commissioner will, in his or her discretion, extend confidentiality to reports or information required under AS 31.05.035 from a well located more than three miles from any unleased land if the owner of the well from which these reports or information are derived makes a sufficient showing that the reports or information contain significant information relating to the valuation of un/eased land beyond the three mile radius. Bergschrund No. 1 lies greater than three miles from unleased acreage which is currently included as part of the State Lease Sale 86A. Fiord No. 2 is located greater than six miles from unleased acreage scheduled to be offered in State Sale 86A. Since granting extended confidentiality for these'wells is discretionary and required a "sufficient showing" to demonstrate its relevance to acreage in Sale 86A, I requested that ARCO provide the information necessary to link Sale 86A acreage to these wells. The interpreted well and seismic data that ARCO presented to me on February 27, 1996, was adequate to make a "sufficient showing." Therefore, I am granting your request for extended confidentiality for these wells until 90 days after State Sale 86A, which is currently scheduled for August 1996. By copy of this letter I am requesting that the Alaska Oil and Gas Conservation Commission extend the confidentiality of data from Bergschnmd No. 1 and Fiord No. 2 until further notice.

Mr. Lynch reports that on the Bergschrund location the helicopter made three passes over the location and no trash or debris was located. "The only manmade feature was the small gravel mound covering the area where the well cellar was." Mr. Lynch reports that on the Fiord #2 location they landed the helicopter and "[t]his site too was free of trash and debris". Mr. Lynch further states: "With elimination of the well stem and thorough cleaning by ARCO there was not much to see. I think AOGCC's decision to eliminate the above ground well locator pipe was a good move for both safety reasons and aesthetics." Based on the above information, final location clearance is hereby approved for these ARCO wells: Bergschrund #1 (PTD 94-026) Fiord #2 (PTD 94-009) Chairman c: Leon Lynch, NRO DNR-DOL Blair Wondzell bew/llar2nsw STATE OF ALASKA Alaska Oil Gas Conservation Commission Anchorage, Alaska 99501-3192 CONFIDENTIAL DATA RELEASE The AOGCC will release confidential well data to authorized DNR/DOG employees.

Fifty seven rotary sidewall samples and two percussion sidewall samples were delivered to Core Laboratories' Anchorage facility by ARCO personnel in April of 1994. The sidewall samples were preserved in small glass jars. Sample Processing Sample Preparation Fifty six rotary and two percussion samples were found suitable for Dean- Stark analysis. Two samples failed in the permeameter. They were first cleaned of drilling mud and cut into shapes approximating right cylinders on a dry saw. The samples were then weighed, placed in thimbles, and loaded into the Dean-Starks. Analysis Techniques Dean-Stark Fluid Saturation Measurements Water was extracted from the sidewall samples by Dean-Stark technique using toluene. Samples were left in Dean-Stark for 48 hours and until a stable water reading was obtained. Recovered waters were measured and the samples were placed in a Dean-Stark with chloroform for hydrocarbon extraction for a minimum of 48 hours. They were removed from cleaning when no cut fluorescence was observed. Extracted samples were dried in convection and vacuum ovens at 180 degrees F. for a minimum of 48 hours, and cooled in a desiccator to room temperature before porosity and permeability were measured. Saturations by Dean-Stark methods were calculated using Equations 1 and 2. So : [((W1 - W2 - H20)/Do)/Vp] x 100 Sw = [H20/Vp] x 100 (1) (2) Where: So = Oil Saturations, Percent Sw = Water Saturation, Percent W1 : Natural Weight W2 : Extracted and Dried Weight H20 = Extracted Water, Density Assumed 1.0 gm/cc Do : Density of Oil Vp : Pore Volume Grain Density Grain volume determinations were performed according to Boyle's Law utilizing Helium in a Auto Porosimeter. Grain density was calculated using Equation 3. Where: Dg : Mg/Vg (3) Dg = Grain Density Vg = Grain Volume Mg = Grain Mass Atmospheric Porosity The samples were measured for bulk volume by mercury displacement at ambient conditions. Porosity was calculated using Equation 4. P : [(Vb-Vg) / Vb)] x 100 (4) Where: P = Porosity, Percent Vb = Bulk Volume Vg = Grain Volume Atmospheric Permeability to Air Rotary samples were loaded into a Hassler type core holder at a confining pressure of 400 psig. Percussion samples were ran at a confining pressure of 200 psig. Permeability calculations were performed as defined by Darcy~s Equation for compressible fluids, Equation 5. Pa x v x 1000 Qa x L x L K = x (5) (P1 - P2)(P1 +P2) Vb Where: K = Permeability v = Gas Viscosity P1 - P2 = Differential Pressure P1 + P2 = Mean Pressure Pa = Atmospheric Pressure Qa = F1 ow Rate L = Length Vb : Bulk Volume Company Well : ARCO ALASKA, INC. : BERGSCHRUND #1 ANALYTICAL PROCE CORE LABORATORIES Field : EXPLORATION Formation : DU RES AND QUAL I T File No.: Date : 28-APR-94 Y ASSURANCE HANDLING & CLEANING ANALYSIS Core Transportation Solvent Extraction Equipment Extraction Time Drying Equipment Drying Time Drying Temperature : Delivered by ARCO : Toluene : Dean-Stark : To stable reading : Convection and vacuum ovens : 48 hours minimum : 180 F.

SAMPLE DISTRIBUTION II. SHOW REPORTS III. BIT RECORD IV. DAILY DRILLING SUMMARY V. INTEGRATED FORMATION LOG (MD), INTEGRATED FORMATION LOG (TVD), DRILLING DATA LOG, AND PRESSURE DATA LOG METHODS GEOLOGIC AND DRILLING DATA WAS COLLECTED AT THE WELLLStTE USING INTEQ'S DRILL MONITOR SYSTEM (DMS). THE SYSTEM IS A COMPUTER BASED DATA COLLECTION-UNIT, USED IN THE ACQUISITION, COMPILATION, AND OUTPUT OF DATA. AI)DITIONAL LITHOLOGIC AND HYDROCARBON EVALUATION WAS PROVIDED BY INTEQ'S ONSITE GEOLOGISTS. METHODS OF ANALYSIS USED FOR EVALUATION ARE PRESENTED IN EXLOG'S MANUAL "MUDLOGGING: PRINCIPLES AND INTERPRETATIONS" (MS-t96). MUDLOG THE MUDLOG FORMAT WAS ESTABLISHED PRIOR TO THE START OF THIS WELL. DATA DISPLAYED ON THE LOG INCLUDED: %LITHOLOGY, INTERPRETED LITHOLOGY, RATE OF PENETRATION, TOTAL GAS, CUTTINGS GAS, CHROMATOGRAPH DATA, AND SHOW QUALITY WHEN PRESENT. A SEPARATE TRACK WAS SET UP TO PRESENT MWD RESISTIVITY EXCLUSIVELY WHILE GAMMA RAY WAS PRESENTED WITH THE RATE OF PENETRATION. TOTAL GAS, RATE OF PENETRATION, CUTTINGS GAS AND GAMMA RAY WERE PLOTTED LINEARLY, WHILE ALL OTHER PAR;~ETERS WERE PLOTTED LOGARITHMICALLY. LOGS WERE PLOTTED AS 2 INCHES PER 100 FEET (1:600), WITH THE EXCEPTION OF THE PRESSURE DATA LOG. DRILL DATA DRILLING DATA MONITORED INCLUDED: RATE OF PENETRATION (ROP) USING THE BLOCK HEIGHT SYSTEM, ROTARY SPEED, HOOKLOAD, WEIGHT ON BIT, TORQUE (MINIMUM, MAXIMUM, AND AVERAGE), MUD FLOW IN AND OUT, MUD TEMPERATURE IN AND OUT, STANDPIPE PRESSURE, P~P STROKES, AND ALL THE MUD PITS. THREE H2S STATIONS WERE MONITORED AT ALL TIMES. THIS DATA WAS PLOTTED ON THE LOGS AS WELL AS BEING DISPLAYED ON THREE REMOTE TERMINALS. FORMATION PRESSURE WAS MONITORED AND PLOTTED. CO.~UNICATION EXLOG PROVIDED ONSITE REMOTE TERMINALS FOR THE DISPLAY OF ALL DRILLING PAR.%METERS. THERE WAS A MODEM CONNECTION WITH A REMOTE TERMINAL IN THE DRILLING OFFICE AND A REMOTE TERMINAL IN THE GEOLOGIST'S OFFICE. AN EXPLOSION PROOF DRILL MONITOR (HADD) WAS PROVIDED FOR THE DRILLER ON THE RIG FLOOR. SAMPLING SAMPLES WERE COLLECTED AT 30 FOOT AND 10 FOOT INTERVALS FROM SURFACE CONDUCTOR AT 110' TO FINAL WELL TD. !0 FOOT SAMPLES WERE COLLECTED WHEN SPECIFIED. 4 WET SAMPLES AND 5 DRY SAMPLES WERE COLLECTED DOWN TO 4130', AT WHICH 5 WET SAMPLES AND 6 DRY SAMPLES WERE COLLECTED, FOR EACH SAMPLING INTERVAL, TO WELL TD. ONE SET OF SAMPLEX TRAYS WAS COLLECTED. ! GALLON MYD SAMPLES WERE COLLECTED EVERY AT 1000' VERTICAL DEPTH INTERVALS AND AT PERTINENT POINTS AS WELL AS ONE SET OF GEO CHEM SAMPLES. ALL SAMPLES WERE TURNED OVER TO AN ARCO REPRESENTATIVE, AT THE WELL SIGHT, FOR SHIPMENT TO ANCHORAGE. A COMPLETE LISTING OF SAMPLE SHIPMENTS CAN BE FOUND IN THE APPENDIX. -4- SECTION 1 110' - 1063 LITHOLOGY THE TOP HOLE SECTION CONSISTED OF CONGLOMERATES, GRAVELS, PEBBLES, AND LOOSE SAND. CLAYSTONE WAS PRESENT, IN MINOR AMOUNTS, NEAR THE TOP OF THE SECTION AND BECAME MORE PREVALENT BY 800'. THIN COAL STRINGERS WERE NOTED THROUGHOUT THE SECTION. ~IULTICOLORED GRAVELS AND CONGLOMERATES WERE PRIMARILY lW~AFICS AND CHERT, WITH MINOR QUARTZ. OCCASIONAL ROUNDED PEBBLES WERE RECOVERED, BUT THE MAJORITY OF THE CUTTINGS WERE BROKEN AND FRACTURED. THE POORLY SORTED SANDS WERE OFTEN PRIMARILY MAFICS, WITH MINOR QUARTZ. THE SAND WAS LOOSELY CONSOLIDATED, ANGULAR, AND CO~4ONLY COARSE GRAINED. THE LIGHT GRAY TO GRAY BROWN CLAYSTONE WAS SOFT AND HYDRATED OCCURING FREQUENTLY WITH THE PRESENCE OF SOFT, DARK BROWN TO BLACK, COAL STRINGERS. TRACES OF PYRITE WERE COMMON IN THE SECTION. DRILL RATE AND GAS DATA THE PENETRATION RATE VARIED FROM A LOW OF 13 FEET PER HOUR, AT 973' MD, TO A HIGH OF 386 FEET PER HOUR, AT 405' MD, AN AVERAGE DRILL RATE OF 90 FEET PER HOUR THROUGH THE SECTION. BACKGROUND GAS WAS LOW, AVERAGING 1 UNIT OR LESS, DOWN TO 350' MD AND THEN INCREASING TO A MAXIMUM FOR THE SECTION, OF 130 UNITS AT 490' I~D. BY 590' THE DITCH GAS HAD SLOWLY DECREASED TO AVERAGE ABOUT 12 UNITS FOR THE REMAINDER OF THE SECTION. METHANE (C1) WAS THE ONLY COMPONENT PRESENT IN THE DITCH GAS DOWN TO 1038' MD AND RANGED FROM A LOW OF 14 PI~, NEAR THE TOP OF THE SECTION, TO A HIGH OF 12600 PPM FOR THE SECTION, AT 491' MD. ETHANE (C2) WAS PICKED UP IN MINOR AMOUNTS, AT 1038' I~D, AND REMAINED TO THE END OF THE SECTION. BLENDER GAS RANGED FROM A LOW OF I UNIT TO A HIGH OF 6 UNITS FOR THE SECTION. OIL AND GAS SHOWS NO OIL OR GAS SHOWS WERE NOTED OVER THIS SECTION OF HOLE. -5- SECTION 2 1063' - 1920' MD LITHOLOGY LIGHT TO MEDIUM GRAY AND GRAY BROWN CLAYSTONE QUICKLY BECAME PREDOMINATE, AT THE TOP OF THE SECTION, AND PREVAILED TO THE END OF THE 12-1/4" HOLE AT 1920'. THE GRAVELS AND CONGLOMERATES OF THE TOP HOLE SECTION DISAPPEARED AND GAVE WAY TO FINE AND MEDIUM SAND. THE SAND QUICKLY DISSIPATED, WITH DEPTH, AND GRADED TO SILTSTONE BY 1310' MD. COPIUS AMOUNTS OF CLAY WAS RECOVERED WITH MOST OF IT WASHING AWAY, WHEN PROCESSING THE SAMPLES FOR EXAMINATION. THE CLAY WAS LIGHT TO MEDIUM GRAY AND GRAY BROWN, SLIGHTLY TO MODERATELY CALCAREOUS, SILTY, AND LOCALLY VERY FINE SANDY. THE CLAYSTONE GRADED TO A SOFT, VERY FINE SANDY, MICRO CARBONACEOUS SILTSTONE IN PARTS OF THE SECTION. AN ABUNDANCE OF TAN TO CREAM TO BUFF SHELL FRAGMENTS WAS NOTED, PARTICULARLY AT 1100' AND 1160' MD, WITH THE REST OF THE SECTION BEING LOCALLY FOSSILIFEROUS. CARBONACEOUS MATERIAL AND TRACES OF PYRITE WERE COMMON WITH SOME COALLY MATERIAL SCATTERED THROUGHOUT. SOFT WAXEY TUFFS WERE NOTED IN THE SAMPLES AFTER 1800' MD. ABUNDANT WOOD WAS OBSERVED IN THE SAMPLES. DRILL RATE AND GAS DATA THE PENETRATION RATE RANGED FROM A LOW OF 29 FEET PER HOUR, AT 1877' MD, TO-A HIGH OF 460 FEET PER HOUR, AT 1564' MD, AND 490 FEET PER HOUR, AT 1621' MD. THE AVERAGE RATE OF PENETRATION WAS ABOUT 150 FEET PER HOUR DOWN TO 1350' MD, INCREASING TO AN AVERAGE OF 220 FEET PER HOUR DOWN TO 1700' MD, AND THEN DECREASING TO AN AVERAGE OF 60 FEET PER HOUR BY 9-5/8" CASING POINT, AT 1920'. DITCH GAS VARIED FROM A LOW OF 8 UNITS BACKGROUND, AT 1127' MD, TO A HIGH OF 638 UNITS, AT 1266' MD.

Sand was noted in the samples to about 2480' MI) and swab gases were recorded, from this section of the hole, for the remainder of the well. Continued to drill ahead through claystone and siltstone while weighting up to 10.6 ppg. By 2520' ~g), the background gas dropped to range from 10 to 50 units with connection gases of 30 to 100 units noted down to 2800' MD. MARCH 18, 1994 3337' - 4143' MD Drilled ahead to 3339' where it was decided to circulate bottoms up and pull bit #2 after drilling 1417 feet in 17.9 hours. The hole was swabbed, for the first 10 stands and remained static for the rest of the trip out. New bit #3, (EC R-417G, TFA=0.54), was picked up with a mud motor and run in the hole. Washed and reamed the last 60' to bottom after tagging a bridge 60 feet off bottom. A trip gas of 840 units was recorded at 1200 strokes, after circulation was started, and 180 units was recorded from bottom. Drilled ahead through claystone and siltstone with shale interbeds noted from about 3615' to about 3810' MD. The bit began to ball up by 3910' MD so a walnut hull sweep was pumped around to clean off the bit and the bottom hole assembly but the attemp was not successful. Circulated bottoms up at 4143' and pulled a short trip to the casing shoe at 1907' in an attempt to clean out the hole and improve the penetration rate. Swabbed the hole for the first 10 stands.

The last 60 feet were washed and reamed to bottom before drilling ahead at 4143'. A maximum short trip gas of 586 units was recorded from bottom. Drilled ahead to 4175' with no improvement in the penetration rate. Bottoms up was circulated out and bit #3 was pulled after drilling 838 feet in 11.4 hours. The mud motor was laid down and new bit #4 (STC FDSSH, 3x13) was picked up to run in the hole. Reamed the hole and logged the last 40' to bottom with the mwd tool. Maximum trip gas recorded was 225 units from bottom. Drilled ahead, with the conventional rotary assembly, through predominate siltstone, claystone and local interbedded sands. Mud weight was 10.6 ppg with an average background gas of about 12 units. -3- DAILY DRILLING SUMMARY (Continued) MARCH 20, 1994 4560' - 4955' KD Continued to drill ahead to 4777' where it was decided to circulate bottoms up and pull out of the hole to pick up a mud motor. Bit #4 cut 602 feet in 18.8 hours. New bit #5 (STC MF15L, 3x14) was picked up, with the mud motor, to run in the hole. Run in the hole to 4700' and washed to bottom while circulating out gas. Maximum recorded trip gas was 1335 units from 1350 strokes after circulation was started. Bottoms up gas was 546 units and still masked by the trip gas from 2400'. Drilled ahead through siltstone and claystone with a mud weight of 10.5 ppg. Background gas averaged about 12 units. MARCH 21, 1994 4955' - 5509' KD Continued to drill ahead through predominate claystone and siltstone. Background gas averaged about 12 units with 10.5 ppg mud in the hole. The clay began to hang up the bottom hole assembly and would not let the bit drill. At 5448' a S.A.P. pill was pumped around the drill collars, while working the pipe, in an attempt to free the stabilizers. At 5448', it was decided to pull an 8 stand short trip to free the drill string. The hole was sticky and swabbing while pulling out, but went back in the hole slick. Maximum short trip gas was 168 units, from the upper sand at 2400', and 28 units from bottom. Drilled ahead, from 5448', but the hole continued to stick the drill string and stall the motor. HARCH 22, 1994 5509' - 5710' KD Continued to drill ahead to 5545' where it was decided to pull the bit out of the hole. The mud system was weighted up to 10.6 ppg while circulating bottoms up. Bit #5 made 768 feet in 25.4 hours. The stack was tested, 250 psi - 3000 psi, after breaking off the bit. The mud motor was laid down and new bit #6 (SEC S44G, 3x14) was picked up and run in the hole to 5530' where the kelly was picked up. Washed the bit to bottom while circulating out gas. Maximum recorded trip gas, at 5545', was 380 units from the upper sand at 2400' and 170 units was noted from bottom. Drilled ahead through siltstone and claystone with local sands and argillaceous siltsones. Background gas averaged about 9 units with 10.6 ppg mud in the hole. KARCH 23, 1994 5710' - 6133' KD Continued to drill ahead to 6133' where circulation was lost. An LCM pill was pumped to bottom and l0 stands were pulled out with the hole sticky and swabbing. The pipe was worked while circulating slowly and spotting LCM. Returns were regained partially and then lost again. -4- DAILY DRILLING SUMMARY (Continued) MARCH 24, 1994 6132' - 6210' MD Finished spotting an LCM pill and let it sit for half an hour. Slow pump rates regained circulation and when full returns were regained, the pump rates were brought up to drilling pressure slowly while circulating out heavy mud. Run in the hole 5 stands and brought the circulating pressure up slowly starting at 25 strokes per minute. Run in the hole to bottom and again slowly brought up the circulating pressure starting at 25 strokes per minute. Drilled ahead, with 10.5 ppg mud in the hole, after full returns were established. At 6210', it was decided to circulate bottoms up and pull bit #6 out of the ground after making 665 feet in 25.7 hours. The first 3 stands were tight and swabbing, but the rest came out slick. Bit #6 was broke off and new bit #7 (SEC GS82F, 2x14, lxll) was picked up to run in the hole. MARCH 25, 1994 6210' - 6626' MD Continued running in the hole to 6180' and picked up the kelly to wash the rest of the way to bottom. Maximum recorded trip gas was 205 units from the upper sand at 2400' while 80 units was reorded from bottom at 6210'. Drilled ahead through siltstone, shale, and claystone with minor volcanic tuffs. Background gas averaged about 15 units with 10.5 ppg mud in the hole. MARCH 26, 1994 6626' - 6868' MD Continued to drill ahead through siltstone and shale to 6288' where it was decided to check the hole and pull a 6 stand short trip. The hole appeared to be okay so the bit was run back to bottom to drill ahead. Maximum recorded short trip gas was 162 units from the upper sand and 98 units from bottom. Drilled ahead through predominate shale. Average background gas was about 25 units with 10.5 ppg mud in the hole. Drilled ahead to 6868' where it was decided to circulate bottoms up and pull bit #7 after cutting 658 feet in 33.3 hours. Finished the trip out and broke off bit #7. New bit #8 (SEC GS82F, 2x14, lxll) was picked up and run in the hole. MARCH 27, 1994 6868' - 7178' MD Run in the hole to 6837' and washed the rest of the way to bottom. Trip gas was 230 units from the upper sand and 50 units from bottom. Drilled ahead through shale to 6886' where sandstone was encountered and a dramatic increase in background gas to a maximum of 435 units at 6912' was recorded. Background gas remained above 100 units until about 6939' and sand was noted in the samples down to about 6970'. Continued to drill ahead performing flow checks at each connection. The background gas dropped to an average of below 20 units while drilling through claystone, shale, and siltstone with 10.5 ppg mud. APPENDIX V. LOGS APPENDIX V.

At 2410'-MD, loose sand was noted in the samples producing a maximum of 347 units background gas. -2- DAILY DRILLING SUNNARY (Continued) KARCH 17, 1994 1930' - 3337' Flow checks were performed while drilling through the interbedded sands. Sand was noted in the samples to about 2480' ~ID and swab gases were recorded, from this section of the hole, for the remainder of the well. Continued to drill ahead through claystone and siltstone while weighting up to 10.6 ppg. By 2520' MD, the background gas dropped to range from 10 to 50 units with connection gases of 30 to 100 units noted down to 2800' ~iD. ~ARCH 18, 1994 3337' - 4143' KD Drilled ahead to 3339' where it was decided to circulate bottoms up and pull bit #2 after drilling 1417 feet in 17.9 hours. The hole was swabbed, for the first 10 stands and remained static for the rest of the trip out. New bit #3, (EC R-417G, TFA=0.54), was picked up with a mud motor and run in the hole. Washed and reamed the last 60' to bottom after tagging a bridge 60 feet off bottom. A trip gas of 840 units was recorded at 1200 strokes, after circulation was started, and 180 units was recorded from bottom. Drilled ahead through claystone and siltstone with shale interbeds noted from about 3615' to about 3810' KD. The bit began to ball up by 3910' KD so a walnut hull sweep was pumped around to clean off the bit and the bottom hole assembly but the attemp was not successful. Circulated bottoms up at 4143' and pulled a short trip to the casing shoe at 1907' in an attempt to clean out the hole and improve the penetration rate. Swabbed the hole for the first 10 stands. Circulated bottoms up at the shoe. MARCH 19, 1994 4143' - 4560' KD Run in the hole to 3144' where a tight spot was encountered. Washed and reamed through the tight spot and run in the hole. The last 60 feet were washed and reamed to bottom before drilling ahead at 4143'. A maximum short trip gas of 586 units was recorded from bottom. Drilled ahead to 4175' with no improvement in the penetration rate. Bottoms up was circulated out and bit #3 was pulled after drilling 838 feet in 11.4 hours. The mud motor was laid down and new bit #4 (STC FDSSH, 3x13) was picked up to run in the hole. Reamed the hole and logged the last 40' to bottom with the mwd tool. Maximum trip gas recorded was 225 units from bottom. Drilled ahead, with the conventional rotary assembly, through predominate siltstone, claystone and local interbedded sands. Mud weight was 10.6 ppg with an average background gas of about 12 units. -9- DAILY DRILLING SUMMARY (Continued) MARCH 20, 1994 4560' - 4955' MD Continued to drill ahead to 4777' where it was decided to circulate bottoms up and pull out of the hole to pick up a mud motor. Bit #4 cut 602 feet in 18.8 hours. New bit #5 (STC MF15L, 3x14) was picked up, with the mud motor, to run in the hole. Run in the hole to 4700' and washed to bottom while circulating out gas. Maximum recorded trip gas was 1335 units from 1350 strokes after circulation was started. Bottoms up gas was 546 units and still masked by the trip gas from 2400'. Drilled ahead through siltstone and claystone with a mud weight of 10.5 ppg. Background gas averaged about 12 units. MARCH 21, 1994 4955' - 5509' MD Continued to drill ahead through predominate claystone and siltstone. Background gas averaged about 12 units with 10.5 ppg mud in the hole. The clay began to hang up the bottom hole assembly and would not let the bit drill. At 5448' a S.A.P. pill was pumped around the drill collars, while working the pipe, in an attempt to free the stabilizers. At 5448', it was decided to pull an 8 stand short trip to free the drill string. The hole was sticky and swabbing while pulling out, but went back in the hole slick. Maximum short trip gas was 168 units, from the upper sand at 2400', and 28 units from bottom. Drilled ahead, from 5448', but the hole continued to stick the drill string and stall the motor. MARCH 22, 1994 5509' - 5710' Continued to drill ahead to 5545' where it was decided to pull the bit out of the hole. The mud system was weighted up to 10.6 ppg while circulating bottoms up. Bit #5 made 768 feet in 25.4 hours. The stack was tested, 250 psi - 3000 psi, after breaking off the bit. The mud motor was laid down and new bit #6 (SEC S44G, 3x14) was picked up and run in the hole to 5530' where the kelly was picked up. Washed the bit to bottom while circulating out gas. Maximum recorded trip gas, at 5545', was 380 units from the upper sand at 2400' and 170 units was noted from bottom. Drilled ahead through siltstone and claystone with local sands and argillaceous siltsones. Background gas averaged about 9 units with 10.6 ppg mud in the hole. ~CH 23, 1994 5710' - 6133' WI) Continued to drill ahead to 6133' where circulation was lost. An LCM pill was pumped to bottom and 10 stands were pulled out with the hole sticky and swabbing. The pipe was worked while circulating slowly and spotting LCM. Returns were regained partially and then lost again. DAILY DRILLING SUMMARY (Continued) ~M{CH 24, 1994 6132' - 6210' MD Finished spotting an LCM pill and let it sit for half an hour. Slow pump rates regained circulation and when full returns were regained, the pump rates were brought up to drilling pressure slowly while circulating out heavy mud. Run in the hole 5 stands and brought the circulating pressure up slowly starting at 25 strokes per minute. Run in the hole to bottom and again slowly brought up the circulating pressure starting at 25 strokes per minute. Drilled ahead, with 10.5 ppg mud in the hole, after full returns were established. At 6210', it was decided to circulate bottoms up and pull bit #6 out of the ground after making 665 feet in 25.7 hours. The first 3 stands were tight and swabbing, but the rest came out slick. Bit #6 was broke off and new bit #7 (SEC GS82F, 2x14, lxll) was picked up to run in the hole. MARCH 25, 1994 6210' - 6626' MD Continued running in the hole to 6180' and picked up the kelly to wash the rest of the way to bottom. Maximum recorded trip gas was 205 units from the upper sand at 2400' while 80 units was reorded from bottom at 6210'. Drilled ahead through siltstone, shale, and claystone with minor volcanic tuffs. Background gas averaged about 15 units with 10.5 ppg mud in the hole. MARCH 26, 1994 6626' - 6868' MD Continued to drill ahead through siltstone and shale to 6288' where it was decided to check the hole and pull a 6 stand short trip. The hole appeared to be okay so the bit was run back to bottom to drill ahead. Maximum recorded short trip gas was 162 units from the upper sand and 98 units from bottom. Drilled ahead through predominate shale. Average background gas was about 25 units with 10.5 ppg mud in the hole. Drilled ahead to 6868' where it was decided to circulate bottoms up and pull bit #7 after cutting 658 feet in 33.3 hours. Finished the trip out and broke off bit #7. New bit #8 (SEC GS82F, 2x14, lxll) was picked up and run in the hole. MARCH 27, 1994 6868' - 7178' MD Run in the hole to 6837' and washed the rest of the way to bottom. Trip gas was 230 units from the upper sand and 50 units from bottom. Drilled ahead through shale to 6886' where sandstone was encountered and a dramatic increase in background gas to a maximum of 435 units at 6912' was recorded. Background gas remained above 100 units until about 6939' and sand was noted in the samples down to about 6970'. Continued to drill ahead performing flow checks at each connection. The background gas dropped to an average of below 20 units while drilling through claystone, shale, and siltstone with 10.5 ppg mud. APPENDIX V. LOGS MEMORANDb, State o.

When I arrive on location the Marker Plate had already been installed and the cellar was in the process of being'back filled. Arco representative G. W. Craig had taken photograph's of the cut and topped off casing prior to welding on the plate. I verified the information bead welded to the plate and remained on location for the filling and mounding of the cellar. As the attached 6 photograph's indicate, the casing was cut off approximately 3.5 feet below ground level and topped off with cement. The Marker Plate was welded to the casing stub and the cellar backed filled and mounded to approximately 6 feet above ground level to allow for settling during break up. ~'~J I Recommend that the commission request a schedule, for conducting Final ~_,¢~ ~...,.~,~.~ Location Clearance Inspections this summer, from all operators involved in exploratory drilling during the 1993/1994 winter season.

The perforation intervals were located at a depth of 6877' to 6932', a mechanical cement retainer was set at 6850' and pressure tested to 1000 psi, 35,000g's of weight was also set on the retainer to verify integrity. Cement was then pumped through the retainer ( 8 bbls.), drill pipe was pulled out of the retainer and 8 bbls. cement was spotted on top of the retainer and pressured tested to 1000 psi. The casing cement retainer was set at 1830' and 15.4 bbls. cement was spotted on top of the retainer and pressure tested to 1000 psi. Another cement retainer was placed at 298' and pressure tested to 1000 psi for the surface casing plug and cemented to surface. The 9/58'" X 7" casing was cemented to surface using the down squeeze method. At this time the surface casing has not been cut off and the marker plate welded on, this will be done in the near future. Summary: I witnessed the plug and abandonment of ARCO's Bergshrund #1 well.

A detailed plug and abandonment procedure is enclosed. ARCO requests a variance to the requirements of 20 AAC 25.120 Well Abandonment Marker. Rather than place an above ground marker over the wellbore, ARCO proposes to weld a cover plate to the casing stub 3' below ground level with the information required in 20 AAC 25.120 (b) bead welded to the top. The location will then be backfilled with gravel. If you have questions or require additional information, please contact Bill Mathews at 263-4607 or myself at 263-4962 in our Anchorage office.

Monday, April 4, 1994: The test was started shortly after midnight and lasted to 10:00 AM this was due to a failure of the lower pipe rams and repeated bonnet failures on the choke manifold. The failures were repaired while I was on location and added considerably to the test time. The accumulator had a excessive recharge time and was up considerably from the last witnessed test. The crew will clean the inlet strainers and try to improve this. While the doors were open on the lower pipe rams I made a visual inspection of the ram bores, these appeared pitted and I mentioned that a BOP inspection should be made by a proofing facility before the next rigup. Recommendation: if this rig is to be activated after this well I feel that the BOPE should be reworked and brought up to a more reliable condition· Summary: I witnessed the weekly BOP test on Rowan rig #33. Test time 10 hours (including repairs), three failures. Attachment:A92JDCBD.XLS ./ ._. / .Dod cc.. ~~ ,~'eco ~.

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. 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. , David W. ~ohnston~ Chairman ~ BY ORDER OF THE COMMISSION dlf/Enclosures cc: Department of Fish & Game, Habitat Section w/o encl.

ARCO will act as operator for itself and Union Texas Petroleum in evaluating acreage previously leased by British Petroleum and Chevron USA, Inc., et al in the 1965 State of Alaska Lease Sale. Both British Petroleum and Chevron USA, Inc. have assigned their leases to ARCO 100%. The proposed well location is approximately 3.25 miles southeast of the SOHIO Nechelik #1. The wellsite will be accessed via ice road originating at KRU 2M Pad. ARCO plans to use Rowan Drilling Company's Rig 33 to drill this well from an ice pad during the winter of 1993-94. Attached find the information required by 20 AAC 25.005(c), 20AAC 25.050 and 20 AAC 25.061. All waste drilling mud and cuttings generated during the drilling of Bergschrund #1 will be hauled to the Kuparuk River Field for temporary storage and eventual processing by ball mill which will grind the cuttings prior to their being injected down an approved disposal well. The TD of this well will be at the base of the Nuiqsut Formation which directly underlies the Kuparuk Formation. H2S has not been encountered in this region in any stratum shallower than the Lisburne Formation. Therefor, ARCO has not included an H2S contingency plan with this Application. However, all drilling mud, cores and produced fluids exiting the wellbore will be monitored for detectable levels of H2S.

All water added to the system should contain adequate KCL to provide the minimum 35,000 mg/l. There should be no freshwater additions to this system. 8. Maintain the pH in the 9.0-9.5 range with KOH except during cored intervals. The pH during coring should be 7.5-8.5. , Maximize all solids control efforts. Run as fine a screens as possible on the shakers. Do not run the desander or desilter. Operation of these units will cause excessive losses of calcium carbonate and liquid. Run the mud cleaner with fine screens throughout this interval. The centrifuge can be used periodically in a "solids stripping" mode to cut mud weight. 8-1/2" Production Hole (Core point to TD) Prior to each core point, the mud will be reconditioned to insure compliance with core fluid specifications. Expect a minimum dilution of 15% with KCL water to re- adjust total solids and to make the system receptive to the following treatments. 1. The pH should be alloWed to drift back to the 7.5-8.5 range. All KOH treatments should be discontinued. 2. The mud should be tested to confirm a minimum of 30 ppb calcium carbonate. Make additions if necessary. . , , The HTHP filtrate (200 °F / 500 psi) should be reduced to the 7-8 cc range with Dextrid LT and Drispac-SL at a 4:1 ratio. This will probably require 4.0 ppb Dextrid LT and 1.0 ppb Drispac-SL. Add and maintain 1.0 ppb Sodium Bromide as a filtrate tracer. Even distribution in the mud is critical. Allow enough circulating time to ensure that coring is done with a homogeneous distribution of the tracer. The NaBr should be added to all batches of original mud, and the dilution fluids while coring. Do not maintain between cores. Be aggressive with Aldacide-G (biocide) treatments to reduce/minimize bacterial degradation. Monitor the residual biocide concentration. 6. Adjust the salinity as required to 35,000-38,000 mg/I with KCL. , Adjust the weight as required using Baracarb-5 (calcium carbonate). If calcium carbonate concentrations exceed 60 ppb, begin using barite as a cost effective alternative. RECEIVED ~:, :~'..:a ~[ & G~s Cons.

Dilution with KCL water is the preferred method for thinning the mud, however "light" Therma-Thin treatments will be allowed. , No fresh water additions should be made at any time. All volume maintenance should be done with additions of KCL water or pre-mixed whole mud. After the final core has been cut, focus on rheological stabilization with KOH and Desco and/or Enviro-Thin in preparation for running and cementing casing. RECEIVED & Gas Oar, s.

O0rrlmissi0n Anchorage The important initial properties would include a pH in the 9-9.5 range, YP in the 5-10 Ibs/100ft2 range, and an APl filtrate in the 8-10 cc range. The initial FV should be in the 35-45 sec/qt range or as dictated by hole conditions. The initial mud weight requirements will be achieved with Baracarb-5 (calcium carbonate) treatments. Increase the mud weight as needed with additions of Baracarb-5. Test the mud to insure that the calcium carbonate stays in the range of 30-60 ppb before reaching core point. If calcium carbonate concentrations exceed 60 ppb, begin using barite as a cost effective alternative. . Mud weight reductions should be accomplished using KCL water dilutions and/or the centrifuge in a "solids stripping" mode. Perform solids analysis at the rig to identify the best method for making mud density reductions. 3. Maintain viscosity with additions of Aquagel and extender or Drispac. Adjust viscosity as needed for adequate hole cleaning. , Treatments with Drispac polymers should be used to control the APl filtrate in the 6-10 cc range or as required based on actual hole conditions. Low viscosity or regular viscosity PAC product will be available. 5. Aquagel concentrations should be kept at 4-8 ppb minimum. Prehydration of the bentonite is required. Prehydrate in fresh water with no caustic. . Control excessive rheology with Therma-Thin treatments (Polymer deflocculant) on an as needed basis. By maintaining a .25-.5 ppb concentration of Therma-Thin in all make-up additions, better rheological stability should be observed. Bergschrund #1 MUD PROGRAM General Overview Utilize a standard Kuparuk type spud mud to drill the 12-1/4" surface hole to the 9- 5/8" casing point (1980'). Use a watered back spud mud to drill out the 9-5/8" shoe to prevent cement contamination of the new KCL-Polymer mud system. Clean the pits and mix a KCL-Polymer mud / core fluid. Displace the spud mud with the KCL-Polymer system and perform the LOT. This mud will be used to drill the 8-1/2" hole to TD (7340'). There are no plans to displace with a new core fluid at core point. The KCL-Polymer system will be reconditioned prior to each core. 12-1/4" Surface Hole . Treat out the excess calcium in the make-up water with Soda Ash. Mix adequate spud mud surface volume with Aquagel/X-tend II to a FV of 70- 100 sec/qt and a YP of 30-35 Ibs/100ft2. Add caustic soda to adjust the pH to the 9-10 range for maximum bentonite yield. , Spud the well with a 9.0 ppg mud weight and increase to 10.0 ppg by the base of the permafrost (990'). Hold minimum mud weight of 10.0 ppg from the base of the permafrost to casing point (1980' MD). Increase weight if needed. , Maintain viscosity at initial levels to the base of the permafrost (990') or as needed to control gravel beds. Decrease viscosity to a FV of 45-70 sec/qt by casing point (1980' MD). 4. PAC treatments can be initiated near casing point to improve well bore stabilization by reducing the APl filtrate to 8-10 cc's. 5. A light Desco-DF treatment prior to POH to run casing will help reduce gel strengths. 6. Maximum utilization of solids control equipment is recommended throughout the surface hole. 7. Prior to POH to run casing and cement, condition and stabilize mud at optimum rheological properties. Thin mud back to a YP of less than 20. 8.

Corrlmission Anchorage PRESSURE ANALYSIS Bergschrund #1 RECEIVED .- FEB '.1 7 o · ~'~i~ u~t & Gas C0r~s. Anchorage A geopressure analysis for the Bergschrund #1 well was performed using site specific seismic data and offset well information from the Nechelik #1 well in the vicinity of the proposed well location. The analysis was performed using ARCO's "GAS" (Geopressure Analysis System) software. Figure 1 shows the existing well data used to determine the regional compaction trend. The coefficients for this compaction trend are listed in the appendix. The offset well sonic data is then converted to mud weight equivalents using another equation called the 'pressure translation gradient'. This is compared to the existing mud weight data from the offset well. The coefficients of the pressure translation gradient are reworked until a close match is obtained between the mud weight actually used and the calculated mud weights from the sonic values. This step is called the well calibration phase and the results are shown in Figure 2. The actual coefficients used are detailed in the appendix. The seismic data is incorporated in the form of detailed velocity analyses around the proposed well site. The velocity analyses are converted to interval transit time (ITT) both in time and in depth , and then converted to mud weight equivalents using the same coefficients derived from the offset well data. For this well the seismic line used was WKE92-14 and the well location is at SP 1251 CDP 2503. The proposed well is planned straight hole, so no deviation information was used. The plots show a permafrost effect and a velocity uncertainty effect in the shallow data. This is not geopressure, but a velocity problem caused by picking up a permafrost velocity shallow in the section. Deeper in the section there is some slight possible geopressure at about 5100 ft. However, the seismic velocities at the location do not appear to be high quality and are not very laterally continuous. Offset mud weights indicate abnormal pressure was not encountered at this interval. Analysis also shows a tremendous kick just below the proposed TD of 7340 feet. Qffset well data shows a major lithologic break at that level. This is not geopressure, but a break in the overburden or compaction trend. The software is not able to compensate for this and considers it geopressure. Aisc attached is a summary plot which shows anticipated, pore pressure, mud weight and fracture gradient curves. The fracture gradient is derived from leak-off tests conducted last two years in the ARCO Fiord #1, Kalubik #1, Kuukpik #3 and Till #1 wells as well as pressure integrity tests conducted in wells drilled by other operators in the Colville Delta area.

Following are the major concerns associated with this request. 1) After extensive study of the 1992 Cirque blowout and the performance of the equipment on Cirque, ARCO Alaska, Inc. has determined that a combination of one 16" line with no 90° turns is the optimum design. 2) Effective operation of remote valves positioned 100 feet from the rig are limited. 3) Prevailing winds on the North Slope during the winter drilling season are generally in the direction of SW to NE. With perpendicular placement of the diverter line, there is minimum exposure of gas blowing back onto an ignition source (see attached weather data). 4) A gas dispersion model named "Focus" has been used to simulate flow out of a 16" single line at varying rates and wind speeds aimed towards the rig. Included with this request are outputs from this simulation.
