March 5, 1998 CORING OPERATIONS Core point will be picked in ~e Moraine Interval using the LWD resistivity log.. l_ow-invasi~_ conng procedures when convenient will be used for the core taken from this well. LOW invasion can be achieved ia most sands so long as coring rate exceeds 30 to 60 feet/hr: Higher rotary speed 80 to 100 rpm, and higher bit weights, 8000 to 12000 lbs will produce codng rates which easily reach 120 feet/hr in good quality sandstone. Rotary speed and bit weig~ needed will depend on mci[ Prol3erties ~ lower rotary s~c=l and higher bit weig~ in poorer quality rock. ARC 412N FD Is the recommended bit for this well. it should core at 60 to 120 feet/hr in sand and has given Iow invasion retiab~Ul3 to 5000 md. Aluminum barrels am-recommended because of the greater mechanical' stmngt~.:-.The spacing between the catcher shoe and core bit should be 0.125 inches at bottom-hole circulating conditions. A larger spacing is set on the surface to compensate for differential expansion between the steel outer barrel and the aluminum inner barrel. Material and Site Preparation in Heated Work Space Upon amval at the dg site, the required core handling ecluipment will be set up in an indoor work space by the Core Lab and Ddlling personnel, preferably in the pipe shed. Inner barrel marking and cutting equipment will be set up and tested. This core handling must take place in a heated space. The cora will start to freeze after 30 minutes exposure to sub-freezing temperature. Do net perl/tit ~ core to fraeze~ Upon completion of the above preparations, the core boxes should be put together and marked with client name, well name, core number, and box number. Inner Barrel Laydown, Cutting, Capping, Transportation at the Rig Site The aluminum inner barrel will be laid down in the core barrel shack and transported to the catwalk with a crane or cat line. Wipe down the outer surface of the inner barrel to remove mud. Locate the top of the core and mark inner barrel. Double stripe red and black, red on dght looking up-hole. Mark depths each foot on outer barrel starting from core top and cut inner barrel into 3-foot lengths using the pipe cutter or chop saw ami' barrel support/clamp. Geoscience will chip off a piece of core for description at the 3' intervals. Cai3 one end of the barrel. Place rubber caps on the upper end of core with stainless steel hose claml3s to hold caps in place. If core sticks out too far for the cap, then use a triple thickness of polyethylene core tubing and clamp with a steel hose clamp. Load 3' sections of inner barrel into core boxes and transport inside a heated vehicle to Kuparuk for transportation to Anchorage. This should be as soon as possible after codng to obtain the most reliable routine and special core plug. Total elapsed time between cuttinq the core and preservin.q it in Anchora.qe should not exceed 48 hours. DO NOT ALLOW CORE TO FRE;7'~ DURING TRANSPORTATION FROM THE WI~I,I=SITE TO ANCHORAGE. CORE PROCESSING IN ANCHORAGE General Core Handling: . Core sampling will be conducted as soon as possible after cutting the core. Sample the core immediately upon arrival at the service laboratory regarclless of the time of day. The service company personnel will be notified when the core is on the way and will pick up the core shipment at the airport once the freight company releases it. The service company should be notified that they may receive up to two 90-foot cores in a single 24-hour period. Exposure to air sl~ould be minimized to avoid evaporation of fluids and wettability changes. March 5, 1998 All routine plug clriiling will be done using lsopar L to remove cuttings. Routine core plu~s will be cut ancl analyzed every one-foot over the entire length of core. ,. Sawing will be clone with a clry saw for small samples such as plugs or w~en cutting out full diameter core sections. Slabbing of the core for geology can be conducted with cooled nitrogen gas to cool Me saw blade. Surface Corn Gamma Log in Anchorage The core is laid out on tables in deptl~ order while still inside the aluminum tubes. The corn remains preserved while*it is gamm~~.'- The core gamma unit is calibrated with a 200 APl gamma ray emitter before every core. The core is placed on a conveyor belt (beginning with the bottom of the core) which moves the core at a constant speed under the gamma detector. The pieces are butted fifight to one another, with no breaks in measurements, until the core is completely logged. Now the mco~ed gamma ray response is digitJ~- anct plotted: Core Lay-Out, Marking and Sawing in Anchorage Processing should begin immediately upon arrival in Anchorage so the core can be rapidly sampled and analysis can be expeclited. Place core inner barrel sections in cle~h order convenient to the layout bench. The core should be laid out on the counter in 5- or 10-foot lengths by a Service Company Lab represe~e. Dump core out of inner barrel sections onto lay-out bench. Core pieces are wiped with dry rags to remove mud,. f'~ed-together, oriented with the apparent up dip at the top, degttt roamed and double stril~ed for orientation. Del~tts shall be marked below the con'esponcling foot line and orientation lines marked with white on the rig~ and yellow on the left using waterproof markers, it is recommended that lumber crayons be used for marXing core surface and Marks-A-Lot markers (red and black, reel on dght) for foil wmppecl core. Mark the locations for the routine core plugs. A 3 inch long routine sample will be marked and sawed to separate it from the core having its top at the foot mark each foot. If vertical plugs am cut these will be obtained from the 3 inch sample located at the foot mark. The slabbing of the core can precede the separation of the routine samples from the core using the saw. In this way the slab will be more continuous and higher quality. Core Slabbing in Anchorage Core slabbing will be conducted as soon as the Gamma Ray is completed. Do not open the inner barrel until you are ready for core layout, marking and slabbing. Since this core is only preserved in capped aluminum barrels, core processing must not be delayed when the core an'ives in Anchorage. Water can move out of the core as a vapor during daily cycles of heating and cooling in the laboratory. The core pieces will be fit together so that the same side of the core is always presented in the slab. The core will be slabbed 1/4-3/4 so that the bedding and dip angle are clearly observable. The 3/4 slab should retain the white and yellow stripe and de~h markings made previously (not a wellsite). Rotate the core 90* from these markings and cut the slab. Slabbing should be conducted using cooled nitrogen to cool the saw blade. Double stripe the 1-inct~ slab for orientation. If scribe lines are present, do not use them as cutting guides; try to preserve them on the 3/4-slab as they will be used to caiculatecl paleocurrent directions. 'i'he 3/4 butt end of the core will be immediately preserved in order to minimize exposure. The 1/4 slab should be placed in a slab box with styrofoam inserts to prevent breakage and in de~h sequence. After photographing the 1/4 slab (white light and ultraviolet), the 1/4 slab should be repackagecl and sent back to ARCO's Bayview Warehouse in Anct~orage for detailed descd~ion work at the following address: Bayview Warehouse Building Attn: Dan Przywojski 619 East Ship Creek Ave. Anchorage, AK 99501 March 5, 1998 Core Preservation in Anct'Jorage The 3/4 core butt is placecl with the top to the left on the bench. This will help insure that the proper core orientation is maintained. When moved to the wrapping stations this orientation is maintained. The wrapping stations must be covered with Oilsorbent tissue to provide a soft surface which will not damage Saran and foil. Wrapping should begin as soon as possible after the core has been slabbed. All of the 3/4 core butt is wrapped with Saran wrap (6 layers), then wrapped with aluminum foil (3 layers) and marked. Wrapped core will be marked with depth using white stick-on labels and a black Marks-A-Lot and with red and black (red on right) orientation lines. The murine samples (3' pieces) should be preserved separately from the other core samples in a given foot in Saran and aluminum foil depth marked and stdpped for orientation. These can then be used for cutting plugs as time and manpower permit, if the plugs will not be cut from a routine core sample until the next day, then it should be coated with CoreSeal to prevent evaporation over night. Next, the 3/4 core butt should be coated with CoreSeal. Coreseal coating should be complete on ali samples in 3 to 4 hours except for samples awaiting core plugs. No samples should remain without CoreSeai protection longer than 8 hours. Glass strapping tape is placed on the foil under the wire to prevent puncture of the foil. Bailing wire is wrapped tightly around the center of the core to facilitate the dipping of the samples in Core Seal. Monitor CoreSeal temperature in melting pot. Temperature should not exceed 330°F. If discolored by being too hot-then replace the CoreSeal. The core should be completely submerged in the dip tank for 1-2 seconds and then hung on the cooling racK. After the Core Seal has cooled (3-5 minutes), the sample should be redipped to insure a proper seal and to help protect the core from damage during shipment. After the second dip, the wire is cut at a point just above the preserved piece and a small amount of Core Seal should be placed over the exposed wire to eliminate a wicking effect. Once all the 3/4 core butt has been preserved and placed in the open core boxes, it should be checked for proper preservation and markings. Occasionally the CoreSeal will be too thick to read the markings. Therefore, if possible, a waterproof marker should be used to mark the appropriate designations on the outside of the sample. Cutting and Trimming Core Plugs in Anchorage- The routine core plugs will be cut from the 3/4 slab at 1-foot intervals over the entire length of core. Routine core plugs should be cut at approximately the same place at each foot, moving only when an obvious fracture or core rubble is observed. Cut the 1.0-inch diameter horizontal plugs parallel to bedding plane using isopar L. The plug will be cut from the butt portion starting at this saw-cut face. The diagram below illustrates the slab and horizontal plug locations. March 5, 1998 ROUTINE CORE SAMPLE 11 S. ABBED FAC~ The plug should be cut completely through the center of the core and as close to the depth mark as possible. Take care to be sure the plugging bit is perpendicular to the slab face, otherwise the plug may need to be trimmed. Dab core plug, if necessary, with an Oilsorbent tissue to remove excess oil immediately after plugging. Trim one end of the core plug with a dry saw so that the final plug is 1.5 inches long. if the plugging bit was not perpendicular to the slab face, first tdm the stab side of the plug 1/8 inch (the width of the saw blade) and then tdm off the end piece so that the resulting plug is 1.5 inches long. Identify plug number on the core plug and end piece. Preserve plug in Saran wrap (6 layem) and aluminum foil (3 layers). Relabel with plug number on the foil. Place wrapped plug in pre-weighed bottle, seal, tape and weigh. Label the bottles with well name, depth, plug number, tare and total weight. Routine Core Plug Ends: Plug end-pieces will be batch cleaned with toulene for 4 days. The end-pieces will be clded over night in a convection oven. Place end-piece in a zip-lock bag and marl( deptl~ and plug number on the package. Indicate eh-piece with' EP following plug number. Please ship by overnight mail to the address listed below:. Steve C. Johnson ARCO Oil & Gas Company (PEC-4) 1600 Summit Avenue Piano, TX 75074 (972) 509,4482 Please call Ken Helmoid at (907) 265-t491 before shipping plug ends so he can coordinate with the Piano Lab. The figure on the next page shows the plug and tdmmed end. March 5, 1998 SC SAMPLE I .25" I .5" END 1.0" Vertical Core Plugs: The routine vertical core plugs will be cut once every foot. These will be I inch diameter by 1.5 inches long cut perpendicular to bedding from the same 3/4 butt section of core used to obtain the horizontal core plug. The location of this core plug in the sample is not critical since mud filtrate invasion will not be measured. This plug can go directly to extraction. Use toluene and batch extract these plugs. Continue extraction until these plugs do not fluoresce when tdchlommethylene is placed on the plug. The plugs can then be dded and brushed in the same manner as the horizontal plugs and permeabilities are then measured. PDPK Mini Permeability to Air in Anchorage The % slab will be measured using the PDPK miniperrneameter in Anchorage. The core will be measured at 5 points per foot clown the center of the core. Core breaks and surface imperfections will be avoided. Core Photography in Anchorage The core will be photographed in white and UV light, with 15 feet per frame. The % slab will be used for the photography, so plug holes will be visible. The lsopar will affect the fluorescent for each plug remnant. Four sets of photographs will be required. ROUTINE CORE ANALYSIS IN THE BAKERSFIELD LABORATORY All horizontal and vertical core plugs will be shipped preserved to Bakersfield for routine core analysis. Dean Stark Analysis The Dean Stark method is used to determine water saturation. The flasks and glassware must be cleaned from the previous use to ensure there is no residual water. Rinse condenser, core chamber ancl flask with fresh toluene and discard the rinse. Weigh a clean, dry Dean Stark flask. Add toluene 120:!:1 cc and pre-Ooil. Che~ sidearm for water and transfer pure toluene in side arm to flasK. Dry side arm. To keep toluene loss to a minimum, keep the system closed except when adding or removing sample. March 5, 1998 The core plug is removed from its preservation materials. The core plug is weighed to an accuracy of ~-0.001 g, placed in a pre-clried and pre-laDeled thimble to trap lost grains ana reweighed to the same precision. If core plugs are soft or poorty consolidated in some intervals, then encase them in Teflon tal3e, aluminum or lead foil and screens prior to the last weight. Obtain individual weights on Teflon, foil, and sc. mens. The plug is then loaded into the Dean Stark apparatus without further delay. Then, seal the apparatus. Perform all tasks for one plug at a time. Toluene is refluxed until no further c~ange in the water volume in the receiver is observed for four hours. Take readings at 8, 12, aha 24 hours. Continue with daily readings if necessary. Soap dispersed in toluene may be used to wa~ water from the condenser. Record the volume of the water to within :L-0.025CC (1.2% PV ~ 10% porosity). If water volume is less than 0.5 cc, pull water from receiver with a sydnge and weigh it. Extract with toluene for at least 2 days in the Dean Stark. Extraction and Drying Change to chloroform (use a second Dean Stark device if that is more convenient). Change chloroform after the first forty-eight hours; then, change it every twenty-four hours. Continue extraction until clean chloroform shows no crude oil color after eight hours. A clean core plug should not fluoresce when tdchioromethane is dropped on it under ultraviolet light. Extraction time should be a minimum of two days and may require as long as a week. Do not use batch cleaning techniques in this step. Dry core plug, and thimble in a convection oven at 180 F for 4 hours. Then, dry the core plug, bag and thimble in a vacuum oven for 24 hours at 180 -~F and then to constant weigh ~-0.02 grams, after four hours additional drying. Cool the plug and thimble over desiccant. Weigh the plug and thimble within :L-O.001 g. Remove plug from thimble. Brush plug to remove fines and weigh again. Porosity Porosity is calculated from the difference in bulk volume and grain volume divided by the bulk volume. The pore volume is the difference between bulk volume and grain volume. That is the value used to calculate saturations. Grain Volume The helium porosimeter will be used to determine the grain volume of ali samples. Plugs from drying are kel3t over clesiccant until ready for grain volume measurement. If the plugs are exposed to laboratory air for more than 30 minutes, they sllould be redded and reweighed. The helium porosimeter should be recalibrated to :L-0.1% twice a day. The porosimeter should be checked with a steel cylinder with a known volume to ~0.1% after every five samples and after a break in instrument usage of greater than one hour. If drift between successive calibrations will _cause grain density to vary ~,O.005 g/cc, calibrate before every plug. Bulk Volume Bulk volume for all plugs will be measured using mercury immersion. Bulk volume will be measured within :L-0.01 cc (~O.05% BY). Maximum depth of immersion in mercury will be the minimum required to yield an accurate bulk volume. The plug must be weighed within ~'-0.001 g before and after the mercury immersion to check for mercury intrusion. Any weight gain greater than 0.04 g (0.0030 cc out of 42 cc approximate bulk volume) will be significant intrusion. Bulk volume will be increased to correct for the calculated mercury intrusion. Permeability to Air Permeability to air is measured on all routine horizontal and vertical core plugs. The fine materials generated while sawing should be cleaned from the plug faces before this measurement is made. Brush the plug faces and blow clean with ~lry compressed air before measuring permeaDility. Marctl 5, 1998 Permeai3ility is measured with 400 psi net ovemurclen pressure. Complete recalibration of permeameter will be I~erformed every two wells. Check plugs of known permeaDility will be used to cl~ec~ calibration daily. Permeability should be measured with a stable air flow rate. Routine horizontal core plugs vail be used in trois measurement only after the completion of bulk volume. Marc~ 5, 1998 CORE TRANSPORT Core Transport From Exploration Drilling Rigs Transport of boxed core samples from the Alpine and Kalubik ddll dgs to the Materials Warehouse for shipping will be coorclinated through the Kuparuk Ddlling Tool House and the Kuparuk Materials Warehouse The Kuparul; Drilling Tool House will arrange transportation of the cores in a heated van from the Alpine a~ Kalubik ddil dgs to the KRU Materials Warehouse where they will be weighed and readied for shipmem to Anchorage and then transport the core samples to the Deadhorse airport, The following procedure should be adhered to: 1.The well site geologist should notify the Kuparuk Drilling Tool House two days in aclvance of anticipated conng. A second call should instruct the Kuparuk Drilling Tool House as to date and pick-up time of the cores at the ddlling rig. Terry Bean/Lewie AIImon 659-7367) 2. An FR (materials transport requisition) filled out on location by the drilling supervisor should read: Ship to: Core Laboratories 600 West $8u~ Ave. Unit D Anchorage, Alaska Hold for pick up by Core Lab. (Scott Kehlar) NOA (907) 349-3541 Do Not Freeze The word Priority should be printed boldly on the FR. The FR will accompany the shipment. 3. Core Lab will supply wooden boxes that hold two three-foot pieces of core. These boxes will weigh appx. 130 LB when full. 4. Dave Childress/Pete Richards (659-7459) at the KRU materials warehouse should be notified a day in advance of the shipment. They sttould be notified again on date and pick-up time of the core and on the departure of the core shipment to KRU materials. $ Materials will inform Scott Kehlar wi Corelab (work 349-3541) as to the flight number, ETA, and airway bill number. Note: Do not allow the core to freeze during transportation from the well site to final destination. Destination address must be written on each core Box shipped. Sample shipments in cardboard boxes will be handled in a similar manner. March 5. 1998 Kalubik ~3 CORING OBJECTNES Analysis by Core Lab will include a gamma-ray scan over the entire com, slabbing and photographing in white and ultraviolet light, and analysis of core plugs (1 horizontal plug/foot and I vertical plug/foot). The core will provide core gamma-ray log, in-situ water saturation, porosity, grain density, horizontal permeability, vertical permeability, and lithology. Micropermeameter measurements (every 0.2 feet) will be collected on the 1/4 slab. Part of the core will be preserved for future engineering studies. Below are general guidelines. The on-site geologist or Renee Hannon may moclify these procedures at any time. GENERAL GUIDELINES The wetisite operations will be minimized and conducted quickly so We core can be transported to Core Lab in Anchorage and then on to Core Lab in Bakersfield, Texas for ali other operations. A summary of operations is listed below:. At The Riq Site A. Use Iow invasion core t3its, 60-foot aluminum inner barrel, 4-inch core diameter, bland water base mud. Lay down, deptl~ mark, double stripe, cut, and cap inner barrel in 3-foot lengttm. Place in core crates, two or three 3-foot lengths to the crate so two men can lift them. Minimize dg site operations and transport the core immediately to Anchorage for immediate processing. Durinq transportation~ the core must not be allowed to freeze. Notify personnel to be at-the airport in Anchorage for pick-up. In Anchoraqe A. C. D. E. E. F. G. Core Lab should meet the core at the airport and begin core processing. Lay out aluminum core barrels and run surface gamma ray log while the core is still preserved in inner barrel. Remove core from inner barrel sections, lay out, and depth mark core. Slab the core 1/4 - 3/4. Mount the 1/4 slab in slab boxes for photographing and viewing. Run the Micropermeameter measurements (every 0.2 feet) on the 1/4 slab. The 3/4 slab needs to be processed and preserved immediately after slabbing each 3' section so tl~at special core analyses are not compromised. Cut the 3/4 slab into three I foot pieces. The top 3" of each 1 foot piece should be cut off of the slab for routine core analysis and the required samples for the State of Alaska. The remaining 9" of each I foot piece should be imme(liately preserved for future SCAL work. Preservation should be done within 48 hours of when the core reached the surface at the 'well site. Cut and tdm the plugs for routine core analysis. Routine core samples are to be sent to Bakersfield for analyses. After photographing the 1/4 slab, repackage it and send it to Anchorage Bayview for detailed description work.

Drilling progressed with only minor difficulties with some bit bailing due to clays. The permafrost ended at approximately 1200', with no gas hydrates detected. The decision was made to T.D. the well at 2:15am, March 2, 1998 at a depth of 7000'. (FID) gas detection and ~ ~ l~tgwatch/FdCrak/DML mudlo~ sP. rvJces commenced on February 20, 1998 at 139' to T.D. below the Nuiqsut. Several significant oil and gas shows were observed in this well and are briefly summarized below. The first significant shows were observed within the Moraine sand from 5383' to 5462'. Strong oil indicators and heavy C-5 chromatography readings were observed at the top, but it was obvious that the sands had pinched out and now graded into a very tight siltstone. These silts were saturated with oil, had a~mg ]:)~tmletzm odor, ]e~'~ree oil in the drilling mud,gave~ bright yellowwhite fluorescence, immediate streaming bdght yellowwhite to yellowgreen cut, and left a moderate yellow residual dng fluorescence. The lower Moraine sands indicated a possible oil reservoir from 5736' to 5752' and 5987' to 5999'. These sands indicated the same fluorescence in the well, with a gas peak of 135u. This zone could maybe be economic. The Kuparuk sand from l];3317--tD-~'35-'3'_ slqowed a definite coarsening Aowztward sequence, but unfortunately only the top 4' out of 31' cored was retained in the core barrel. These 4' showed abundant tar with small interbedded finer grained stringer that were free from tar. These sands were saturated with oil, had a strong petroleum odor, a possible tar seal on the top (hopefully), left free oil in the ddlling mud, gave a bright yellowwhite fluorescence, immediate streaming bright yellowwhite to yellowgreen cut, and left a moderate yellow residual dng fluorescence. The Nuiqsut sand was a surprise. From 6559' to 6618', a 265u gas peak was observed, with strong oil indicators and heavy C-5 chromatography readings. These sands were also saturated with oil, had a strong petroleum odor, left free oil in the ddlling mud, gave a bright yellowwhite fluorescence, immediate streaming bright yellowwhite to yellowgreen cut, and left a moderate yellow residual dng fluorescence. One thing was definitely noticed clud~he codngofihe welL It is still difficuitio _retain core in the core catcher, losing 27' of 3t' total, tt appears to have slid out through the bottom of the catcher after it had been broken off before the tdp. Perhaps a PVC core barrel may aid in keeping the core inside the barrel, or checking the inner diameter of the barrel versus the inner diameter of the core bit, and adjusting for washout. Overall, I would gauge the well teJ~3eamoderate-success. Theoil column was-prover+for the Kuparuk and the Nuiqsut in this well, but the MOraine.sands definitely pinched out.

ARCO Alaska, Inc. hereby applies for sundry approval with a variance to plug and abandon the ARCO Kalubik #3, permit number 98-05. A detailed plug and abandonment procedure is enclosed. ARCO requests a variance to the requirements of 20 AAC 25.105 (1) for the cement plug # 1 (6100'-7000') placed as shown at total depth on the attached diagram. ARCO proposes to place plug #1 in the well per 20 AAC 25.105 (fl) using caliper hole volumes plus 20 % excess cement volume without recording the actual location or integrity. Plug #1 at total depth will be placed on the bottom of the hole which will prevent any chance of the cement falling downhole. The cement plug #2 across the surface casing shoe will be set with a retainer as per20 AAC25.105 (g2) and will be pressure tested to verify integrity. The surface cement plug #3 will be set on top of a bridge plug and pressure tested to verify integrity.

Dear Mr. Zanghi: We have rcvicv,'ed ARCO's letters dated January 27 and 30. 1998. as supplemented by' .','our Fcbruarv 9 letter, for a waiver to 20 AAC 25.080(d)(4). The waiver would allow ARCO to dispose of cement rinsatc from Alpine I Pool #6) and Kalubik (Doyen #141) exploratoo' wells dov,'n thc annuli of wells located on another pad. specifically whichever well Parker #245 is drilling at time of disposal. Alternatively, ARCO requests authorization to dispose cement rinsate down thc annulus of well CD1-22 after it is drilled and meets annular disposal criteria. Cement rinsatc is generated from washing cement-mixing cquipment after cementing operations. The x olume of rinsatc is small, about 3040 barrels per cementing operation. While not exempt, it is primarily water and does not e.xhibit an,,- characteristics of a hazardous waste. Because cement nnsate has not been downhole, it cannot be considered a Class II fluid and therefore cannot be disposed of in a Class II well. Consequently. if not disposed down the annulus of an approved ,,','ell. it must bc hauled to Pad 3 for disposal. The commission docs not bclicvc it is prudent to use Pad; for disposing of cement rinsate. As the principle Class l facility on the North Slope. Pad 3 handles non-hazardous, industrial oil,,' wastes. The limited capacity of Pad 3 should not bc squandered in processing cement rinsatc. which is essentially water. The commission concludes that cement rinsate from Alpine and Kalubik exploratoo, wells may be transported to Parker #245 for disposal, or alternatively to CD 1-22 after meeting disposal criteria. This approval is for thc following wells.

Inc. Kalubik No. 3 January 29, 1998 IT APPEARING THAT: . ARCO Alaska, Inc. submitted an application dated January 12. 1998, requesting exception to the well spacing provisions of Title 20 AAC 25.055 (a)(1) to allow drilling of the ARCO Kalubik No. 3 exploration oil well to a bottom-hole location in an undefined oil pool within 500 feet of a quarter section line in Harrison Bay, south of Thetus Island in the Beaufort Sea. Notice of opportunity for public hearing was published in the Anchorage Daily News on January 14. 1998 pursuant to 20 AAC 25.540. 3. No protests to the application were received. FINDINGS: . o The ARCO Kalubik No. 3 exploration oil well will be drilled as a straight hole from a surface location of 423' feet from the south line and 147 feet from the west line of Section 28, Township 14 North and Range 07 East Umiat Meridian. ARCO is the sole working interest owner of the subject and all offsetting drilling units. An exception to the well spacing provisions of Title 20 AAC 25.055 (a)(1) is necessary to allow the drilling of this well. Conservation Order No. 4 January. 29. 1998 Paze 2 CONCLUSION: Granting a spacing exception to allow drilling of the ARCO Kalubik No. 3 well will not result in waste nor jeopardize correlative rights. NOW, THEREFORE, IT IS ORDERED: ARCO Alaska.

Project Description ARCO Alaska Inc., (AAI) proposes to drill two exploration wells in Harrison Bay, offshore of the Colville River Delta in the Kuupik Unit, these locations are still proposed, but are not expected to change significantly. Kalubik #2 Section 15, Township 13N and Range 7E of the Umiat Meridian. Kalubik #3 Section 28, Township 14N and Range 7E of the Umiat Meridian. The wells 4511 be drilled from two icepads that will be accessed by an ice road. AAI hopes to drill in early to mid-February. The wells will be plugged and abandoned upon completion of the project. A more complete description of the project may be found in the Plan of Operations and other permit applications originally distributed by AAI. ~-_..2 printed on recyc'.ed 2aoer D ~' ~. ~, Mr. Mark Major January 16, 1998 Kalubik Wells AK9711-0lOG Scope of this Review Your November 5, 1997 letter to me identified four existing state permits that will apply to this project: Temporary Water Use Permits (LAS 18597 and LAS 14396), Air Quality Control Permit to Operate (No. 9673-AA002), and Fish Habitat Permit (FG97-III-0261). The Fish Habitat Permit is no longer required because the ice roads and the ice pads are located outside of the AS 16.05.870 jurisdictional boundary of the DFG. In addition, as authorized by General Concurrence (GC)-34 and GC-5 on the "B" List, permit (LAS 21669) related to the ice roads has been issued by DNR. As described in GC-34, activities related to ice roads have already been found consistent with the Alaska Coastal Management Program (ACMP). This review addresses activities related to the proposed drilling of oil and gas exploration wells Kalubik #2 and Kalubik #3. Permits covered by this review are listed below: Alaska Department of Environmental Conservation - Temporary storage of Solid Waste - Oil Discharge Prevention and Contingency Plan (amendment to Kuparuk Field and Pipeline Plan Number 9734-CP-4125) - PSD Avoidance Air Quality Control Permit to Operate for an Exploration Well Alaska Department of Natural Resources - Lease Operations Approval - Geophysical Exploration Permit Alaska Oil and Gas Conservation Comission (AOGCC) - permit to drill Consistency Determination Based on the review of your project by the Alaska Departments of Environmental Conservation (DEC). Fish and Game (DFG), and Natural Resources (DNR) and the North Slope Borough coastal district, the state concurs with your certification that the project is consistent with the AC,XlP provided the conditions outlined in the following stipulations are met. The following stipulations will be placed on the amendment to the Kupamk Field and Pipeline Oil Discharge Prevention and Contingency Plan (9734~CP-4125) issued by DEC: 1) Exploratory oil drilling operations are prohibited after April 1, 1998. Mr. Mark Major January. 16, 1998 Kalubik Wells AK9711-01OG 2) Prior to the onset of drilling operations, provide as part of the plan a description of each oil storage container greater than 10,000 gallons used in conjunction with the operation, including specifics regarding the number, type, capacity, product stored, age, design, construction, and condition. Storage tanks greater than 10,000 gallons used for well flow tests must also be included. Note: The oil storage tanks over 10, 000 gallons used in connection with this operation must be inspected and meet all applicable spill prevention requirements prior to being placed into service. Oil storage tanks over 1 O, 000 gallons in capacity, including portable tanks, are subject to the A?i 653 inspection and spillprevention requirements oft8 A/lC 75. 065 and ]8,4AC 75. 075. The dates of any requiredAPI 653 inspections for regulated oil storage tanks must also be noted in the plan. Inspection reports must be available at the facilily for DEC examination once operations begin. 3) Prior to the onset of drilling operations, provide as part of the contingency plan the following: (a) The precise description of the geographic location of each well to be drilled [18 AAC 75.425(e)(3)(A)]; " As-built drawings depicting the physical layout of each well pad, including drill rig, oil storage tanks, camp facilities and access points [18 AAC 75.425(e)(1)(H)]. 4) Notice of Changed Relationship with Response Contractor. Because the plan relies on the use of response contractor(s) for its implementation, the plan holder must immediately notify the DEC in xaq'iting of any change in the contractual relationship with the plan holder's response contractor(s), and of any event including but not limited to any breach by either party to the response contract that may excuse a response contractor from performing, that indicates a response contractor may fail or refuse to perform, or that may otherwise affect the response, prevention, or preparedness capabilities described in the approved plan. Rationale: Stipulations I through 3 are required to protect water quality, [6 AAC 80.140 Air, Land and Water Quality standard]. The following conditions are attached to the Lease Operations Approval and Geophysical Exploration permit for this project issued by DNR: Mr. Mark Major January. 16, 1998 Kalubik Wells AK9711-01OG 5) Operation of Vehicles. ao Vehicles must be operated in a manner such that the vegetative mat is not disturbed, and the blading or removal of vegetative cover is prohibited except as approved by DNR. b. Filling of low spots and smoothing by the use of snow and ice is allo~ved. The use of ground contact vehicles for off-road travel is subject to regional cross- country travel openings and closure notices issued by the Department of Natural Resources (DNR). Operations are restricted to the winter seasonal opening. After April 15, the use of ground contact vehicles is subject to termination within 72 hours of written notification from DNR. d. The winter operation of ground contact vehicles for off-road travel must be limited to areas where ground frost and snow cover are adequate to prevent damage to the' vegetative mat and underlying substrate. Rationale: This stipulation is intended to protect the vegetation from being removed from the underl)'ing substrate exposing soils to thermal degradation or hydraulic erosion and to protect the surface waters and habitat from possible contamination through the loss of h)'drocarbons or an), other hazardous substance, [6 AAC 80. 040, Coastal Development standard: 6 A.4C 80. 130. Habitats standard; 6AAC 80.140, Air, Land, and Water QualiO; standard]. 6) ..q. olid Waste and Debris. Trails, campsites, and work areas must be kept clean. All solid waste including incinerator residue and fuel drums shall be back hauled to a solid waste disposal site approved by the Department of Environmental Conservation. b. Trash, survey lath, roadway markers, and other debris shall be picked up and properly disposed of prior to freeze-up of the following winter. Rationale: This stipulation is intended to prevent accumulation of solid waste on the tundra and to prevent the loss of and~or contamination of habitat and to protect state lands from unauthorized solid waste disposal or burial, [6 AAC 80.130, Habitats standard; 6,4,4 C 80. 040, Coastal Development standard.]. Mr. Mark Major January.' 16, 1998 Kalubik Wells AK9711-01OG 7) Fuel and hazardous substances. Secondary containmentI shall be provided for fuel and hazardous substances-'. a. Container3 marking. All independent fuel and hazardous substance containers shall be marked with the contents and the permittee's or contractors name using paint or a permanent label. (Note: The permittee is ultimately responsible for contractor's compliance with these standard conditions.) bo Fuel and hazardous substance transfers. Secondary containment or a surface liner4 must be placed under all container or vehicle fuel tank inlet and outlet points, hose connections, and hose ends during fuel or hazardous substance transfers. Appropriate spill response equipment must be on hand during any transfer or handling of fuel and hazardous substances to respond to a spill of up ~o five gallons. Transfer operation shall be attended by trained personnel at all times. Vehicle refueling shall not occur within the annual flood plain or tidelands. Storing containers within 100 feet of water bodies. Containers with a volume larger than 55 gallons which contain fuel or hazardous substances shall not ge stored within 100 feet of a water body. do Exceptions. The review coordinating agency, after consultation with other resource agencies and affected coastal districts, may under unique or special circumstances grant exceptions to this stipulation on a case-by-case basis. Request for exceptions should be made to the review coordinating agency. Spill notification. The lessee or permittee shall immediately notify DNR (or the appropriate land manager) and DEC by phone of any unauthorized discharges of oil to ~Secondary containment means an impermeable diked area or portable impermeable containment structure capable of containing 110 percent of the volume of the largest independent container. Double wailed tanks do not qualify as secondary containment unless an exception is granted for a particular tank. "Hazardous substances are defined under AS 46.03.826(5) as a) and element or compound which, when it enters the axmosphcre, water, or land, presents an imminent and substantial danger to the public health or welfare, including fish, animals, or ~,egetation, (b) oil, or (c) a substance defined as a hazardous substance under 42 U.S.C. 9601(14). 3Containers means any item which is used to hold fuel or hazardous substances. The includes tanks, drums, double-walled tanks, portable testing facilities, fuel tanks on small equipment such as light plants and generators, flow test holding tanks, slop mi tanks, bladders, and bags. Manifold tanks must be considered as single independent containers. Vehicles, including mobde seismic tanks, are not intended to be included under this definition. 4Surface liner is any safe, non-permeable container (e.g., drip pans, fold-a-tanks, etc) designed to catch and hold fluids for the purpose of preventing spills. Surface liners should be of adequate size and volume based on worst-case spill risk. Mr. Mark Major January 16. 1998 Kalubik Wells AK9711-01OG water, any discharge of hazardous substances (other than oil), and any discharge of oil greater that 55 gallons solely to land and outside an impermeable revetment. Ifa discharge of oil is greater than 10 gallons but less than 55 gallons, it must be reported within 48 hours by phone or fax. If a discharge is less than 10 gallons, it may be reported in writing on a monthly basis. If an unauthorized discharge greater than 55 gallons is made to a secondary containment, if must be reported within 48 hours by phone or fax. 9) Ail fires and explosions must also be reported. The DNR 24 hour spill report number is (907)451-2678; the fax number is (907)451- 2751. DNR or the appropriate land manager and DEC shall be supplied with all follow- up incident reports. The DEC oil spill report number is (800)478-9300. Rationale: Stipulations 9 through l l are intended to protect the surface waters and the chemical characteristics of habitat that contribute to its ability to support life from possible contamination through the loss of hydrocarbons or any other hazardous substance by reducing the escapement o f fuel, promoting early detection, and decreasing response time, [6 AAC 80. 040, Coastal Development standard; 6,4AC 80.130, Habitats standard; 6 AAC 80.140, Air, Land, and Water ~_.uality standard_/. The lbllowing stipulations will only be attached to the DNR Geophysical Exploration Permit: 10) Movement of equipment through willow (Salix) stands must be avoided wherever possible. Rationale: This stipulation is intended to protect the area's sparse willow stands which contribute to biological diversity in the area, and are valuable for browse, cover, and erosion control, [6 AAC 80.130, Habitats standardJ. 11) Equipment, other than vessels, must not enter open water areas of a watercourse during winter. Ice or snow bridges and approach ramps constructed at river, slough, or stream crossings must be substantially free of extraneous material (i.e., soil, rock, wood, or vegetation) and must be removed or breached before spring breakup. Alterations of the banks ora watercourse are prohibited. The structures must be breached or fractured prior to breakup so that their breakup rate coincides with those of naturally occurring ice formations in the area. This should be accomplished so as not to damage or disturb the vegetation of the terrain nor introduce dirt or debris into the waterways. Mr. Mark Major January. 16, 1998 Katubik Wells AK9711-01OG Rationale: Stipulations 13 and 14 are intended to protect the water quality and habitat of overwintering fish by preventing the introduction of sediments into the water, and the disruption of natural drainage patterns, [6 A,4C 80.130, Habitats standard; 6 d_AC 80.140, Air, Land and Water Quality standard]. 13) Unless approved by DNR, in consultation with the Department of Fish and Game, operations must avoid occupied grizzly bear dens by ½ mile. Known den locations shall be obtained from (DFG) Habitat and Restoration Division, Dick Shideler (Fairbanks 459-7283) prior to starting operations. Previously undocumented dens encountered in the field must be reported to the above and subsequently avoided by a distance to be determined on a case by case basis through consultation with the applicant, DNR, and DFG. 14) Unless approved by the DNR in consultation with the U.S. Fish and Wildlife Service (USFWS), operations must avoid known polar bear dens by one mile. Known den locations shall be obtained from the USFWS (786-3424) prior to starting operations. Previously undocumented dens encountered in the field must be reported to the above and subsequently avoided by a distance to be determined on a case by case basis through consultation with the applicant, DNR, and the USFWS. Rationale: Stipulations 15 and 16 are intended to prevent the unnecessary disturbance of hibernating or denning bears that might result from interaction with equipment, personnel, and the vibroseis sweep, [6 AAC 80.130, Habitats standard./. 15) To avoid additional freeze do,am of deep-water pools harboring overwintering fish, watercourses shall be crossed at shallow riffle areas from point bar to point bar. Compaction or removal of the insulating snow cover from the deep water pool areas of rivers must be avoided. Rationale: This stipulation is intended to avoid additional freeze down of deep-water pools harboring overwintering fish. Deep water pools that do not freeze solid during the long arctic winter are limited in abundance and fish depending on these sources may have few alternatives once the area freezes, [6 AAC 80. 130, Habitats standard]. 16) Should any historic, prehistoric, or archaeological site, or camp, either active or abandoned, be discovered during the course of field operations, the Commissioner of DNR and the North Slope Borough shall be promptly notified. Rationale: [6 AA C 80. ] 50, Historic. Pre-Historic, and Archeological Resource standard]. Mr. Mark Major January 16, 1998 Kalubik Wells AK9711-010G Advisories 1) The DFG requests that AAI consider orienting ice pads and arranging pad layouts in relation to prevailing wind direction to minimize drifting snow that can provide hiding places for polar bears. BP Exploration (Alaska) Inc. has adopted this procedure as routine practice for its exploratory pads, and AAI may wish to do likewise. 2) The DFG requests that AAI provide final ice pad locations to reviewing state resource agencies prior to ice pad construction. 3) The Kalubik sea ice road staked route provided by AAI (letter, January 8, 1998) departs shore just outside the DFG's jurisdictional boundary, for the Colville River mouth, and the locations of Kalubik #2 and Kalubik #3 also fall outside the jurisdictional boundary. The DFG therefore will not be required to issue Fish Habitat Permit FG97-III-0285 (draft provided with DFG ACMP consistency determination dated November 25, 1997) to AAI for Kalubik activities in the Colville River Delta. Please be advised that westward deviation from the staked ice road route in the vicinity of PI-7 (AAI drawing NSK 6.01-d260) would intersect DFG's Colville River Delta jurisdictional boundary and require a Fish Habitat Permit. 4) The DEC, Air Quality Monitoring Program advises that in order for the well drilling program to be consistent with the Alaska Coastal Management Program, AAI may need to propose operational/emission constraints upon the drill rig activities to comply with ambient air quality standards and increments. 5) The North Slope Borough advises Ami to form a Nuiqsut response team that will be trained to assist in an emergency. This group would also provide local knowledge of ice conditions in the river and early warning for the onset of break up. A specific timeline to remove all equipment from the Colville Delta is highly recommended, preferably by April 1. The potential for ice override during the spring or if an early break-up occurs, is a likely scenario to happen due to the unusually warm winter conditions. s) The North Slope Borough advises AAI to perform a study of the impacts by seismic and drilling operations on the young of the year of the dominant species of the local fishery, the Arctic Cisco. The potential for harm may exist to the smallest fish due to the location of the drillsite and seismic activities. The Colville is a rearing and staging area for Arctic Cisco, a main food source for the village of Nuiqsut and should be studied for effects. From a study of Arctic Cisco we can learn how to minimize the negative impacts for Mr. Mark Major January 16, 1998 Kalubik Wells AK9711-010G future projects. A copy of this study should be sent to the reviewing parties for reference. 7) Please be advised that although the state has found the project consistent with the ACMP, based on your project description and any stipulations contained herein, you are still required to meet all applicable state and federal laws and regulations. Your consistency determination may include reference to specific laws and regulations, but this in no way precludes your responsibility to comply with other applicable laws and regulations. 8) If changes to the approved project are proposed prior to or during its siting, construction, or operation, you are required to contact this office immediately to determine if further review and approval of the revised project is necessary. If the actual use differs from the approved use contained in the project description, the state may amend the state approvals listed in this consistency determination. Elevation You must respond ~vithin five calendar days of your receipt of this proposed determination to indicate whether or not you concur with this determination. If you, the applicant, are not prepared to concur within the five-day period, you may either: (a) request an extension of the review schedule pursuant to 6 AAC 50.110(b)(8) if you need more time to consider this determination, or (b) request that the state reconsider this determination, by submitting a written statement requesting "elevation" of the determination, describing your concerns, and proposing an alternative consistency determination. This alternative determination must demonstrate how your project is consistent with the referenced standards of the ACMP and district policies. Other review participants with elevation rights pursuant to 6 AAC 50.0700) may also request an elevation if they submit the information required in (b) above to DGC within five calendar days of receipt of the proposed determination. Petition Citizens of the North Slope Borough coastal district, who submitted wTitten consistency comments on this project on or before the comment deadline established in accordance with 6 A:\C 50.070(e), may file a petition under AS 46.40.100(b)(1) seeking a review by the Coastal Policy Council of this proposed consistency determination. Any petition must be filed with this Mr. Mark Major January. 16, 1998 Kalubik Wells AK9711-01OG I0 office within five calendar days after issuance of the proposed consistency determination. The petition must: (a) (b) (c) (d) show how the district coastal management plan is not being implemented, enforced, or complied with; include the petitioner's previous written comment on the consistency of the project; describe how the petitioner believes his or her previous consistency comment was not fairly considered by the coordinating agency during the consistency review; and provide the petitioner's mailing and street address, telephone number and, if available, fax number. I f DGC does not receive a request for extension or an elevation statement from you, the . applicant, or any other review participant with elevation rights, or a petition from a citizen of an affected coastal district meeting the requirements outlined above within the deadlines specified above, this proposed consistency determination will be issued as a final consistency determination. This proposed consistency determination does not obligate DNR to issue authorization under AS 38.05 nor does it supersede the statutory obligations thereunder. You may not proceed with any specific land use activity on state lands until authorized by DNR.

Johnston, Chairman Alaska Oil and Gas Conservation Commission 3001 Porcupine Drive Anchorage, Alaska 99501-3192 RECEIVED Re: Application for Permit to Drill ARCO Kalubik #3 JAN ! £ 1998 Dear Commissioner Johnston, Alaska Oil & Gas Cons. Commission Anchorage ARCO Alaska, Inc. hereby applies for a Permit to Drill an onshore exploratory well, the ARCO Kalubik #3, on State Lease ADL 355035 near the mouth of the Colville River. ARCO will act as operator for itself and Union Texas Petroleum in evaluating this acreage. The proposed surface location is approximately 3 miles northwest of the ARCO Kalubik #1 drilled in 1992. The wellsite will be accessed via ice road as shown on the attached map. ARCO plans to use the Doyon Rig 141 to drill this well from an ice pad during the winter of 1998. Attached find the information required by 20 AAC 25.005(c) and 20 AAC 25.061. All waste drilling mud and cuttings generated during the drilling of this well will be hauled to either the Kuparuk River Field or Prudhoe Bay Field for temporary storage and eventual processing for injection down an approved disposal well. The TD of this well will be in 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. Therefore, ARCO has not included an H2S contingency plan with this Application and requests an exemption from the H2S requirements. However, all drilling mud, cores and produced fluids exiting the wellbore will be monitored for detectable levels of H2S. ARCO also requests an exception to the shale density requirement in 20 AAC 25.033(e,2,D). The shale density technique does not work well in Alaska due to the variable composition of the shales and the chemical used in the shale density column is listed as an exceptional health hazard. The surface location of the Kalubik #3 well is in very shallow water offshore of the Colville Delta and is subject to offshore well design regulations. ARCO requests a waiver of the requirement to install both structural casing at 100' below the mudline and conductor casing in the interval from 300' to 1000' below the mudline. ARCO proposes to set a conventional well conductor at 100' below the mudline and drill the surface hole to 3000'. It is our opinion that the well can be safely drilled with a conductor set at 100' and that setting both the structural pipe and the deep conductor does not add any additional level of safety. This opinion is based on the following comments. The water depth at the well location is estimated to be 3'-4'. This seawater will all be frozen during the entire well operation. The well will be 242-2603 ARCO Alaskal ,mc. · .... ~~ Post Office Box 100360 Anchorage, Alask~ 995i0~0360 .~ drille-/~frsh~rlt~ g~~e~t~e pad that will be constructed to have 3' of freeboard ovm the surrounding grounded sea ice. With the pad surrounded by grounded ice there are no horizontal ice loading forces. The well will be drilled using a conventional North Slope development drilling rig. Although the well is technically offshore, the well should only experience the normal forces that an onshore well would experience thus eliminating the need for higher structural strength at surface. This well is an expendable exploration well and will be plugged and abandoned this season. Therefore the well would not be subjected to breakup and open water sea forces. The review of the offset exploration wells and the shallow hazards review from seismic data do not identify any unusual drilling hazards in the surface hole interval which might require heavier mud weights. Geotechnical and log information indicate that permafrost is not present at the surface in this area but does exist in the deeper interval from approximately 700' to 1400'. Therefore the planned conductor at 100' will be set in unfrozen firm soils which will provide good anchorage for the conductor and should not be subject to permafrost melting. Eliminating the deeper offshore conductor will result in significant time and cost savings that would be incurred to both install the additional casing string and to remove the string during the abandonment operations.

Wydrinski PRC-D 1139 509-4325 D. Gingrich ATO-1458 F. Johnson ATO- 1292 This letter is to summarize the pore pressure work done in the Kalubik area using the above data. The wireline sonic data was used to predict the pressure in the Kalubik #1; and the seismic velocity was used for the seismic lines. There is no large pressure anomaly for this prospect well. Seismic Processing: The accuracy of Geopressure prediction is highly dependent upon the accuracy of the seismic stacking velocity field that is used as input. This velocity field is generated by picking velocities at every CDP location with an automated high resolution velocity analysis program (UHCI process developed by AEPT). This process produces a very accurate and densely sampled velocity field to cover every CDP location. The RMS velocities that are output have been smoothed over 300 ms vertically and 150 CDPs horizontally to normalize any instabilities in the velocity field that might result from noise, lack of signal, or variations in CDP fold. Pressure PrediCtion Procedure: ARCO,s PPFG software was used to calculate the pore pressures. These were the steps taken to calculate the pressures: 1) 2) The Gamma Ray and Neutron Density Porosity log from the Kalubik #1, was used to distinguish the sand intervals from the shales. A Normal Compaction Trend Line (NCTL) was determined in the shales from 'the wireline sonic data for the Kalubik #1. This line indicates the predicted sonic value if these shales were normally compacted (no pressure). If the sonic delta T increases past the compaction line, (this change is A^T), then there is an indication of an increase in pressure. The compaction trend line of this project has the same slope (-4.5 e-05) as the Tam and Colevile projects; and the intercept (185) was similar. 3) Using the mud weight data from the Kalubik #1, the Pleistocene Trend model was used to convert the AAT to equivalent mud weight (PP). This equation is · PP = C2 * AAT 2 q. C1 . AAT + Co where C2 =-1.34 e-05; C~ = .0062; Co -.465 This is the same equation that was used in the Tam and Coleville project. 4) This NCTL and Translational Trend was used for the seismic line. 5) The Eaton model with a West Cameron' Poisons Ratio was used to calculate the fracture gradient. Well Discussion: Kalubik #1 Figure #1 is the pore pressure prediction results from the Kalubik #1. The left portion of the plot is the wireline sonic DT (black curve) and the NCTL (red line). The right section is the predicted pore pressure (blue line), the actual mud weights (green line) and the fracture gradient (red line). From this plot the mud weight increase to 10.3 ppg occurred at 5700'. The DST pressures were in agreement with pore pressure. The Leak Off Test (LOT) at 3,700' is 1.0 ppg higher than the predicted fracture gradient but the LOT at 7,000' is in good agreement. There were two kerogene intervals 5,750' to 5,900' and 7,300' to 7,600'. These intervals have higher Gamma Ray and DT values. Note: The DT from 1,200' to 1,750' is higher than the NCTL. This is right below the permafrost and these formations appear to be more unconsolidated than the deeper portion of the well. No shallow hazard was encountered in this well. Seismic Line WKE93-24 Figure #2 is the pore pressure prediction for this line. The well TIE is the approximate location of the Proposed location (CDP 3148) and Kalubik #1 was at CDP 2792. From this data there is a section of higher pore pressure from 1,500' to 2,000' and below 6,000' From the wireline data in Kalubik # 1, the shallow increase in DT was due to unconsolidated rock below the permafrost. Figure//3 is an overlay of the wireline DT (black curve) from Kalubik # 1, Travel Time from the seismic at Kalubik #1 CDP 2792 (WKE93-24_DT, red curve) and Travel Time for the Proposed Location CDP (TIE-DT, green curve). From this overlay, the seismic DT at the Proposed Location is the same as in the Kalubik # 1. Therefore the same pressure results would be expected. At CDPs 3325 and 3750 there may be shallow hazard. If these are potential locations then another seismic line through this CDP should be processed to confirrn this information. In Figure//3 the curves ERHOB (black curve) is the wireline density and WKE93-24_RHOB (red curve) is the synthetic density from the seismic DT at the Kalubik #1 CDP. Figure//4 is the pore pressure prediction for the Proposed Location (Kalubik Prospect). The left portion is the Seismic Travel Time (black curve) and the NCTL (red line). The right portion is the pore pressure prediction (blue curve) and fracture gradient (red curve). The expected increase in mud weight will near 6,000'. The LOT from the Kalubik #1 fits well with the fracture gradient prediction. Figure//5 is the pore pressure prediction for the seismic line with Time on the Y-axis. Conclusions 1) There are no indications of geopressure for the proposed Kalubik Prospect. 2) The anomaly at 1500' for the Kalubik Prospect is due to uncompacted formations below the permafrost. 3) At 6,000' there will be an increase in mud weight to about 10.5 ppg.. 5) The Pliestocene model was used for pore pressure prediction. 6) The Eaton / West Cameron model was used for fracture pressure prediction.
