Purpose of Well BEAUFORT SEA BLOCK 54 WELL NO. 1 page 4 The Beaufort Sea Block 54 well will be drilled to investigate a potential pinchout trap of Cretaceous age sands on the north flank of the Barrow Arch. A complete testing program will be conducted if necessary to assist in evaluating potential accumulations. 2. Proposed Site The proposed site of the well is to be adjacent to Cross Island. 3. Site Description The drill site, located approximately 15 miles northeast of Prudhoe Bay, will be a gravel pad situated within a cove on the west side of Cross Island. Water depths of six to eight feet may be found in the cove. During the proposed operating season, the area should be covered by landfast ice 5-6' thick. This landfast ice should remain essentially static throughout the winter and we anticipate no ice override of the drill site. However, we plan to install a suitable ice monitoring system and the rig will be positioned somewhat to the lee side of Cross Island so as to provide protection against ice override. page 5 If override becomes a significant concern several optional procedures may be employed to minimize the danger to personnel and equipment. These decisions will be made based on the existing conditions and could include the following: a. Have minimum equipment and personnel ready until protection from override is obtained by natural offshore ridging. b. Induce early offshore ridging by slotting the ice on the seaward side of the Cross Island. c. Provide barrier berms to the seaward side of the rig. d. As a last resort, secure the well and remove personnel and as much equipment as possible. The following Figure 1 shows Cross Island in respect to the surrounding area and Figure 2 shows the location of the drill site in more detail. Additional data on the island and surrounding area is provided in Attachment D, "Environmental Conditions in the Vicinity of Cross Island" by oceanographic Services, Inc.

Proposed Operational Time Schedule The timing sequence of the operation is shown in the following Figure 3 and is designed to be compatible with all lease stipulations and attendant ordinances concerning the ecology of the area. Survey work, the transporting of some equipment and supplies will begin after August 15. Such work will be preparing the rig pad, the well cellar, erecting the camp and stockpiling consumables. It is anticipated that the rig can be moved in by barge, or ACV, erected, and drilling started by 1 November 1982. It is expected that the well can be completed and tested ana the rig moved out before deterioration of the ice in April. If such is not the case the well would be temporarily plugged and abandoned, then completed and tested the following year. In the event a two year program is required to complete the well, the rig could be moved off the gravel island, then back to the site the following winter or stacked on location, pending approval of the agencies concerned.

Name and Address of Operator This well will be operated by' Tenneco Oil Co. P. O. Box 2511 Houston, TX 77001 6. Area Wildlife and Fish Local observations and area studies indicate the proposed winter operation will not hinder the habits of the area wildlife. Note Attachment "D" page 11. 7. Native Settlements No villages are in the vicinity of the proposed location so the drilling operations should not directly affect any of the local population. 8. Biological Monitorin~ Biological populations or habitats that require additional protection, will be monitored and surveyed as directed by the Director of the Division of Minerals & Energy Management. In addition if any area of biological significance should be discovered it will be reported immediately and protected until advice is received from the Director. page 8 9. Environment Training Environmental training required will be conducted in an approved manner. 10. Access Roads Vehicle access to the drilling location will be from the Prudhoe Bay field road system and a sea ice road. The ice road will comprise a cleared route approximately 15 miles long over the shore fast ice. This road will be approximately 30' wide in grounded ice areas, but will be maintained wider to facilitate snow clearing. The rig and all heavy components will be transported by barge or ACV to the island. The ice road will be utilized for rig removal. Utilization of the ice is a proven aspect of Arctic drilling technology. Grounded and ungrounded ice has been utilized for ice roads to supply drilling rigs with great success. page 9 .~.~.. ll. Materials Required To provide a better foundation for the rig and to give additional free board height to the drilling pad, as protection from the ice, approximately llO,000 cubic yards of gravel will be moved in. This will make a drilling location of approximately four acres, 8 feet above sea level. The building of this pad will require an Army Corps. of Engineers Permit. 12. Fuel Storage Fuel will be stored in double walled steel tanks, or single wall with a containment dike of snow and ice. These dikes, based on prior Arctic experience, should be competent during the operating period. Safety precautions, procedures, flow diagrams, etc., will be developed for fuel facilities and spills. Leaks should be non-existent or minimal. All personnel will be trained in safety and procedures to avoid possible mishaps. 13. Blowout Prevention Program and Equipment All operating procedures at the location, whether automated or directly controlled by Company or Contractor personnel, are specifically designed and organized to prevent accidental oil spills. Continued emphasis is page l0 placed on the prevention of spills, but at the same time, contingency, 'emergency clean-up eqiupment and procedures are kept in a state of readiness. The primary method of blowout prevention utilizes hydrostatic pressures exerted by sufficient density drilling mud to prevent undesired flow into the wellbore. In the unlikely event primary well control is lost, the following surface equipment would be utilized for secondary containment of any formation fluid influx into the wellbore. The rig will be equipped with a 20" 2,000 psi working pressure (wp) annular diverter system installed on 80 ft. of 20" H-40 94# conductor pipe while drilling the 17-1/2" surface hole to 2,700'. The diverter lines will be vented in different directions to provide downwind diversion. After running and cementing 13-3/8" 72# L-80 surface casing at 2,700', a blowout preventer (BOPE) consisting of.three 13-5/8" 10,000 psi wp rams, a 13-5/8" lO,O00 psi wp annular preventer, and a two-choke manifold will be installed. After installation of the BOPE, it will be thoroughly tested for leaks using diesel fuel. It will be pressured tested and function tested as required in 20 AAC 25.035. This same procedure will also be followed after setting 9-5/8" casing. Automatic and manual monitoring equipment will be installed to detect any abnormal variation in the mua system and drilling parameters. A mud logging unit, manned by experienced personnel, will be in continuous use while drilling, and it will monitor page 11 formation pressure, hydrocarbon shows, loss or gain in the mud pits, rate 'of penetration, etc. In the event that the well "kicks," the BOPE will be used to shut in the well immediately and confine the pressure within a closed system. The casing program is designed so that any anticipated formation pressures can be shut in at the surface without breaking down the casing seat. The Company representatives assigned to the drill site will have extensive training, together with actual experience in controlling and killing kicks. These personnel will be further supported by well-trained drilling crews approved by the Company. Pressure resulting from a kick will be circulated out using the balanced bottom hole pressure method, and the well will be restored to its normal operating condition. Tenneco Oil Company is a member of the Alaska Beaufort Sea Oilspill Response Body (ABSORB) so in the unlikely event that secondary control of the well is lost and premature well flow occurs, the full scope of the ABSORB organization and equipment is provided for control and clean-up purposes. Our Spill Contingency Plan is provided as Attachment 2. In addition to the ABSORB response to a blowout, well kill procedures will be initiated. These are highly specialized and designed to the conditions of the blowout. Capping and killing procedures are usually successful but directional relief wells are frequently started as soon as possible as an page 12 additional assurance of successfully regaining well control. A 'number of other drilling rigs on the North Slope would be available for such and emergency well if this were necessary. 14. Casin9 Program The casing and cementing program is briefly shown below.

Food Service The drilling contractor will be responsible for insuring that the food and potable water is adequate, handled and prepared properly. Cleanliness will be maintained in kitchen and dining facilities in compliance with all rules of "Good Housekeeping". 16. Drilling Rig Camp The camp area will be composed of steel modular structures and will be sufficient to provide safety, comfort and convenience for all personnel. 17. Location of Fresh Water and Treatment Water for the camp and rig will be provided from fresh water generator units or snow melt devices on the rig. Alternatively, on shore sources may be used. page 14 ~-~-'-~ 18. Waste Disposal Burnable wastes will be disposed of in an incinerator at location, and Other waste material will be transported to an approved location on land for disposal. 19. Site Restoration The well may have to be suspended and reentered later if problems force the rig to be removed prior to adequate evaluation or testing. However, upon final completion of all operations, tne well will be plugged and abandoned. This will be done in compliance with all appropriate regulations in force at that time and will include removing of all casing and/or well head material to below ground level. The gravel drilling pad that was constructed will become a permanent part of Cross Island. It will be windrowed and seeded under the direction of the Department of Fish and Game so as to enhance that habitat of the eider ducks and other wild-fowl species that utilize this island as a nesting ground in the summer months. 20. H2S The probability of encountering H2S in the drilling of this well is considered to be minimal. However, H2S monitoring systems will be page 15 provided and maintained by the mud logging unit so that in the unlikely event H2S is encountered, it will be detected and proper precautions can be initiated. page 16 Attachment A GEOLOGICAL PROGNOSIS AND PROGRAM May 1982 page 17 RECOMMENDATION TO DRILL BEAUFORT SEA BLOCK 54 WELL NO. 1 Operator: Tenneco Oil Company Location: Beaufort Sea Offshore Block 54 Approximately 9,630' FEL & 5,200' FSL Distance from Shore: 15 miles northeast of Arco East Dock 12 miles northeast of Niakuk Islands 12 miles north of Sag Delta area Adjacent Leaseholders: (See Figure 4) Tenneco to East anO West; /~noco to South and Southwest; Union to Southeast; open to North, Northeast and Northwest Proposed TD: 14,200' This should be adequate to penetrate all the prospective sedimentary section above economic basement and allow sufficient penetration of the pre-Mississippian to identify and log it. they - Cities Exxon-Unical Gulf se.s66so% · -----.-- ..---.., · _ - - : 74.13 Am·rod· · ~ ~ Morolhon 0 " Uflical ~ ..~ ~, 0.*j ' EKxon-Arco I I~,.e7% !Tenneco !~:~nneco Ill' '1' -- -- .~Z'1'- ----' Il liamDIItOn I / ' I. !!

In a 20 hole core drilling program conducted by the U.S.G.S. in February and march of 1979 within the lease sale area, permafrost was encountered in all but five holes. The deepest of those five only went to 140 feet. The shallowest permafrost was encountered at 46 feet and the maximum amount penetrated was 261 feet, the bit still in permafrost at TD. In the R.I.S.T. well, the actual amount of permafrost was difficult to determine but its base could be picked at 1,030' KB. The Amoco well drilling on No Name Island about 13,000 feet to the southeast of this location is reported to have no permafrost. Gas could be trapped below the permafrost zone, if it exists, or gas hydrates could also be present. If gas hydrates are encountered some free gas, either as pockets within the hydrate zone, or trapped beneath page 21 it would be anticipated. These have not presented any particular problems elsewhere in the area. B. Abnormal Pressure Reference to drilling histories and the plotting of the resistivities of shales encountered in area wells suggest the possibility that some higher than normal pressures could be encountered. The most likely zones for geopressures to occur are in the deep-water shales in he basal part of the Seabee Formation and below the Neocomian unconformity. These would be expected from about 10,555' to 12,650' and below 13,150', respectively. Most wells have been successfully drilled with about 10 ppg muU. The maximum known mud weight used in the area was at the Exxon #1 Alaska State A on Flaxman Island where 15.3 ppg was employed. WELL EVALUATION A. Mud Logging Continuous mud logging should be started from below the 20" casing show and continued to total depth. In addition to the standard sample logging, gas detection and pore pressure services, hydrogen sulphide (H2S) and carbon dioxide (C02) detection systems should be provided as well as continuous automatic mud weighing systems. page 22 B. Coring 1. Conventional Cores Conventional cores will be taken only if hole conditions and time permit. No coring is anticipated above 12,650'. Below that point it will be at the discretion of the well site geologist and only if potential reservoir rocks are encountered. 2. Sidewall Cores Numerous sidewall cores are anticipated, primarily for paleontologic and reservoir information and also for geochemical purposes. Coring points will be determined by the wellsite geologist. Wireline Lo. ggin~: Logging Aprox.

Additional log runs may be made if abnormal pressure, adverse hole conditions or other circumstances warrant doing so. page 23 Formation Testing: A. Wireline Testing The Schlumberger Repeat Fromation Tester (RFT) may be used to determine possible hydrocarbon zones or potential reservoirs where other data is lacking or inconclusive. The wellsite geologist will determine such test points, to be based on the mud log, drilling time, wireline logs or other data. B. Drillstem Testing No open hole DSTs are anticipated. If testing is warranted a 7" liner will be run for this purpose. .Drilling Cuttings' A. Dry Cuttings Samples will be collected every 30' from below the 20" casing s~oe to approximately 10,000'. Ten foot intervals will be sampled below lO,O00'. page 24 B. Wet Cuttings Wet cuttings should be collected at the same intervals as the dry cuttings but should only be lightly rinsed and placed in plastic bags. C. Canned Geochemical Samples These samples should be collected at 100' intervals from below the 20" conductor pipe to TD. They should be placed directly in a quart container, sprayed with Bactericide "Zephrin Chloride", ana sealed. Geochemical Evaluation' Tenneco will evaluate the source rock and thermal maturity of the section. Routine determination of total organic carbon, hydrocarbon solubles, vitrinite reflectance and kerogen coloration will be carried out. Canned samples will be available for head-space gas anlysis or carbon isotope work. B. iostrati 9raphy' Biostratigraphic work will be contracted out. Contractor will be determined at a later date. The unwashed samples will be available for biostrati§raphic information ano sidewall cores will be taken for this purpose with the number and location to be decided by the wellsite geologist. page 25 Geological Supervision: The Tenneco wellsite geologist will be responsible for all geologic functions during drilling of the well. He will be responsible for daily geologic reporting to the Houston office. A coordinator for all geologic evauation of the well will be located in Houston. Security: Only Tenneco and authorized personnel are to be admitted into the mud logging and wireline logging units at all times. All logs (original and copies) are to be secured at all times and unwanted copies are to be destroyed. The radio-room is to be cleared of all non-Tenneco personnel during the times of morning reports or reporting of confidential matters to the Houston office. All distribution of geologic well data is to be handled out of the Houston office. Only authorized personnel will be allowed on the drillfloor when cores are pulled and laid out on the drillfloor. This will also apply when wireline formation test tools are being.unloaded. Authorized personnel page 26 will be Tenneco personnel, contractors' personnel working on the dri'llfloor, and all other persons authorized by the Tenneco operations supervisor. Supp1 ementary Notes' Specific procedures will be given as to the disposition of samples, shipping or transmittal of data and samples at a later date. page 27 Attachment B DRILLING PROGNOSIS AND DETAILED OPERATIONAL DATA May, 1982 page 28 ~-'~ Prognosis to Drill Lease: Beaufort Sea Block 54 District: Frontier Exploration Projected Depth: 14,200' Location: Beaufort Sea Offshore tract Block 54 approximately 9,630' FEL & 5,200' FSL Well No.: 1 Area: Alaska-Beaufort Sea Est.

BLOWOUT PREVENTION PROGRAM AND EQUIPMENT All operating procedures at the location, whether automated or directly controlled by Company or Contractor personnel, are specifically designed and organized to prevent a loss of well control. Continued emphasis is placed on well control, but at the same time, contingency and emergency clean-up equipment and procedures are kept in a state of readiness. The primary method of blowout prevention utilizes hydrostatic pressures exerted by sufficient density drilling mud to prevent undesired flow into the wellbore. In the unlikely event primary well control is lost, the following surface equipment would be utilized for secondary containment of formation fluid influx into the wellbore. The rig will be equipped with a 20" 2000 psi wp annular diverter system installed on 80 ft. of 20" H-40 94# conductor pipe while drilling the 17-1/2" surface hole to 2700' (see Figure A-B-5).

After running and cementing 13-3/8" 72# L-80 surface casing at 2700', a blowout preventer (BOPE) consisting of three 13-5/8" lO,000 psi wp rams, a 13-5/8" 10,000 psi wp annular preventer, and a two-choke manifold will be installed (see Figure A-B-6). After installation of the BOPE, it will be thoroughly tested for leaks using diesel fuel. It will be tested at least weekly thereafter, as well as prior to drilling out casing shoes. Operational tests and crew drills will be conducted daily. This same procedure will also be followed after setting 9-5/8" casing. Primary well control will be maintained by over-balancing formation pressure with a column of drilling fluid. Automatic and manual monitoring equipment will be installed to detect any abnormal variation in the mud system and drilling parameters. A mud logging unit, manned by experienced personnel, will be in continuous use while drilling, and it will monitor formation pressure, hydrocarbon shows, and loss or gain in the mud pits as well as other downhole conditions. In the event that the well "kicks," the BOPE will be used to shut in the well and confine the pressure within a closed system. The casing program is designed so any anticipated formation pressures can be shut in at the surface without breaking down the casing shoe. The Company representatives assigned to the drill site will have extensive training, together with actual experience in controlling anO killing kicks. These B.O.P.

Data from area wells indicate this should give a good casing seat and shut off the perma frost that exists from surface to approximately 1,000'. Because this permafrost might act as a caprock, small accumulations of gas could be present in the surface hole. It is anticipated that gas would be at normal pressures. (The surface hole should be carefully monitored while drilling and tripping.) Also, mud should be kept as cool as possible to prevent thawing of the permafrost. page 48 PROGRAM 1.

The liner would be run where drilling is in jeopardy due to hole conditions. The depth of the well is such that running a 7" liner could prevent reaching TD at 14,200'. Slower penetration rates and shorter bit life associated with 5-7/8" bits, along with the time required to run and cement liner will lengthen the drilling time. No operations are planned to extend past the winter operating season. PROGRAM 1. Drill 8-3/8" hole to TD of 14,200' or as hole conditions dictate. Coring should be at a minimum. 2. Run open hole logs as per Logging Program. Install 7" rams in BOP stack if liner is to be run. 3. Rig up and run 7" 32# Soo-95 Buttress casing as follows: Float shoe Two joints casing Float collar Sufficient 7", 32#, Soo-95 casing for a 200 liner lap Hanger Liner packer Tieback sleeve page 57 CASING RUNNING NOTES a.

Pick up sufficient 3-1/2" drill pipe and 4-3/4" collars and RIH with 5-7/8" bit. Clean out to float collar. 10. Pressure test lap to 3000 psi surface pressure. (Do not test before 12 hours after CIP). Squeeze if necessary. ll. If liner cement job tests to 3000 psi, drill out float equipment and cement then begin drilling new 5-7/8" hole. 12. Drill 30' of new hole below the 7" shoe and run static leakoff test. Drill to TD log, test and or P&A as required. 4-1/2" Liner The possibility exists that a 4-1/2" liner may be run from the 7" liner shoe to TD. This possibility is remote, but most be provided for if hole conditions require running the 7" liner prior to T.D., and then shows are encountered below the 7" liner. The 4-1/2" liner will be run in the same manner as the 7", and a detailed procedure will be issued at a later date. TESTING PROGRAM If testing is necessary to evaluate this well, we propose to test in a fashion compatible with the production expected and the Arctic climate. page 59 All tests will be performed with tubing and packers in the hole and the tree installed. Detailed procedures will be forthcoming when and if any testing should be done. The following Figure A-B-7 is a general layout of the surface testing equipment that could be used for a production test. Plu~ and Abandonment Pro~ram Several plug and abandonment alternatives exist and will be covered in the following.

'f~' 3) To provide communication patterns to assure coordination of efforts. 4) To provide reference materials to those responsible for the various duties that occur as the result of a spill. This plan is considered supplementary to the ABSORB Contingency Plan and contains only elements of contingency planning pertaining to Tenneco Oil · Company's philosophy and organization. The bulk of the above listed preparation, training, equipment lists, organization and response actions will be defined and controlled by the ABSORB Contingency Plan and organization. It is through such cooperative efforts by the operating companies that the greatest efficiencies can be obtained in the unlikely event that an oil spill does occur during our planned exploratory operation. INTRODUCTION page 6 6 Oil spills have generated complex technical, legal, and public relations problems for the companies involved. Prior planning can help avoid or minimize such difficulties. It cannot be emphasized too strongly that the best way to handle oil spills is to prevent their occurrence. Good housekeeping, adequate equipment maintenance, and adherence to proper operational procedures are the best insurance against oil spills. If, in spite of the best care, accidental spills do occur, they will require the immediate coordination and efforts of many company departments, and perhaps, contractors and/or outside agencies. This offshore contingency plan is designed to guide Tenneco Oil Company personnel in the quick and effective response to the problems presented by accidental spills. Its primary goal is to limit, as far as practicable, damage to property, wildlife, or the ecology from such a spill. Within this offshore Contingency Plan and primarily in the referenced ABSORB Plan, you will find descriptions of the duties that are to be discharged when oil is spilled. It provides affected personnel with procedures for handling such spills effectively. Some of the procedures are mandatory, and they are so identified, others are merely suggested, as their application might be dependent on the conditions of the spill. lol ' 1.2 1.3 1.4 1. GENERAL INFORMATION page 67 Facility Name Beaufort Sea Block 54 Well No. 1 Tj/pe of Facility Exploratory Well Location of Facility The location will be on a gravel pad situated within a cove on the west end of Cross Island. The drill site about 15 miles from the Prudhoe Bay East Docks on a heading of 35°. Figure 1.1 is a map showing its location. Site Description The drill site will be a gravel pad approximately 250' by 650'. It is located within a shallow water cove on the west end of Cross Island. maximum elevation on the pad will be eight feet. LEASE SALE BOUNDARY i .__q ~F~AUrO~T SEA MIDWAY ISLANDS . '~ ~ L ~ CRO.

By the middle of October the ice is usually continuous between the drill site and shore and by early November the ice extends from the location to the polar pack. In early freezeup the ice may be susceptible to large movements but stabilizes as the ice thickens. These movements will not affect the Beaufort Sea Block 54 well as all equipment will be located on a gravel pad with the exception of the access ice road, and temporary ice berms for secondary spill containment. 1.5 Prgposed Operational Time Schedule Survey work and the transporting of equipment and supplies will begin after August 15. It is anticipated that the rig can be moved in by barge or ACV erected, and drilling started by November 1, 1982. It is hoped the well can be completed and tested and the rig movea out before deterioration of the ice strip in late April. If such is not the case the well would be temporarily plugged and abandoned, then completed and tested the following year. In the event a two year program is required to complete the well, the rig could be moved off the gravel pad then back to the location the following winter or stack on the gravel pad pending approval of page 69 the agencies concerned. It is noted that by State Stipulation No. 9, downhole activities are limited to the time period of November 1 to March 31 unless special permission is granted by the DMEM. 1.6 Name and Address of Operator This well will be operated by Tenneco Oil Company P. O. Box 2511 Houston, TX 77001 2.1 2. DETAILS AS SPECIFIED IN 18 AAC 75.310 Tenneco Oil Company is a member of the Alaska Beaufort Sea Oil Spill Reponse Body (ABSORB) and as such the Oil Spill Contingency Plan for Beaufort Sea Block 54 Well No. 1 will be the ABSORB Contingency Plan supplemented with specific information relative to our company and this well. References will be made to the ABSORB Plan but its pertinent sections will not De duplicated an~ included here as the plan in its entirety will be in all agency files along with sample participation contracts in fullfillment of 18 ACC 75.310 (a) (1) 2.2 A detailed description of the proposed manner of oil discharge containment and clean up operations, including operating manuals, page 70 personnel, organization, logistics, and communications is as follows: 2.2.1 Containment In the extremely unlikely event of a very large spill, containment would be provided in the form of a large containment area to one side of the gravel pad. This system would involve an ice sealed containment berm approximately two to three feet above the sea ice and about 200 feet square. The containment area would provide sufficient volume for a large spill from the rig (20,000) barrels). Additional areas could be quickly bermed in the same manner with on-site bulldozers and earth moving equipment should a larger area be needed. Fuel will be stored in double-walled steel tanks or in tanks which will be surrounded by snow and ice berms constructed for · secondary containment. Once the snow berm is constructed, the area will be lined with herculite and the berms will be sprayeU with water which, when frozen will form a complete ice/herculite containment area. Any fuel from a spill coming in contact with the berm would be at ambient temperatures. Inasmuch as the drilling program calls for completion prior to breakup, these dikes will be adequate during the period of operations. 2.2.2 Response page 71 An alert and response procedure will become effective immediately upon the observance of any oil spill. 2.2.2.l Any employee Observing an oil spill of any quantity must immediately notify his supervisor (Mandatory) 2.2.2.2 2.2.2.3 The supervisor will confirm the spill, its cause and basic nature, and notify the Drilling Supervisor. (Mandatory) The Drilling Supervisor will make a preliminary determination of the seriousness of the spill and initiate corrective and clean up measures. (Mandatory) 2.2.2.4 The Drilling Supervisor will notify the onshore Drilling Superintendent. If assistance is needed the Drilling Superintendent will provide personnel and equipment as needed up to and including the full scope response team as specified in ABSORB Plan Section 2. (Mandatory) 2~2.3 Clean Up Equipment page 72 A portable spill countermeasure building containing sorbent materials and clean up tools will be located near the wellsite. This equipment is designed to clean up minor spills. In the event a larger spill does occur additonal equipment and materials are available through the ABSORB Organization as specified in the Logistics and Equipment Section 6 and 7 of the ABSORB Plan. 2.2.4 Clean Up Operations Clean up operations will be conducted in accordance with Section 3 "Response Action Outline" of the ABSORB manual 'using the techniques of cleanup as described in Section 8. Operating manuals on spill response and equipment operation will be provided by ABSORB as will the basic organization for logistics and communications. These functions are covered in the ABSORB Manual Sections 2, 5, and 6. Personnel requirements for a Spill Response will be provided as much as possible with Tenneco employees and supplemented with qualified contract people and other company response te~ms as provided for in Section 2.2.1 of the ABSORB Manual. page 73 2.3 The name, title, business address, telex number, and business and after hours telephone or contact for key personnel who are assigned to elements of the Beaufort Sea Block 54 Well No. 1 operation and who will constitute the responSe team organization in case of a spill event cannot be provided at this time. As we assemble our personnel for this well a response team organizaion will be provided as in the following Figure 2-1 and in accordance with ABSORB Manual Section 2. These assignments will be updated during the progress of the well so that current availability and accountability is known by all concerned. 2.4 A communications plan to direct and coordinate clean up personnel is covered in Section 5 of the ABSORB manual and will provide the basics of such emergency communications reuirements. Inth case of minor spills, and to initiate mobilization of the more complex ABSORB System, existing communication eqiupment on the rig and in mobile units will be used. 2.5 An estimate of the size, frequency, and location of the maximum probable and median oil discharge is difficult to predict with any precision. Table 2.1 shows quantities that sould be consdered as estimates of spill events which might be reasonably conceived. In addition to this table, spill scenarios are provided in much more detail in Section 4 of the ABSORAB Contingency Plan. This data includes maximum possible and "worst case" estimates from two different sources. _ [ _.

As an indication of this low probability, note the following quotes: "No oil spill in excess of 50 barrels has been recorded during exploratory drilling, to our knowledge, in any offshore area throughout the world," Elmer P. Danenberger, 1976, U.S.G.S. Circular 741 page 9. Further more, "A study for Environment Canada indicated the probability of having a large blowout during exploration in the Beaufort Sea was in the range of 1 in lO0,O00 to 1 in 1,000,000," S. L Ross, Oilweek, May 19, 1980, page 52. We thus assume the probability of a maximum to medium oil discharge on this well to be extremely small. The most probable occurrance would be a minor spill associated with fuel transfer or maintenance and would occur in the fuel storage or power plant areas. These areas are provided with containment facilities and would be easily cleaned up. 2.6 Means of oil discharge detection, including surveillance schedules, leak detection, monitoring systems, spill detection systems and spill detection instrumentation- 2.6.1 Fuel and Lube The total operation of the Beaufort Sea Block 54 well will be under the constant surveillance of both operator and rig supervisors, and daily inspections will be made to assure no oil leaks or minor spills have occured. A personnel working in the fuel handling page 75 area or other areas where spills could occur will be thoroughly trained in handling procedures and how to respond in the event an accidental spil 1 does occur. 2.6.2 Blowout Prevention The source of a major spill would be from a well blowout and all operating procedures at the location, whether automated or directly controlled by Company or Contractor personnel, are specifically designed and organized to prevent such blowouts. The primary method of blowout prevention utilizes hydrostatic pressures exerted by sufficient density drilling mud to prevent undesired flow into the wellbore. In the unlikely event primary well control is lost, the following surface equipment would be utilized for secondar~ containment of influx into the wellbore. The rig will be equipped with a 20" 2000 psi W.P. annular diverter system instal.led on 80 ft. of 20" H-40 94# conductor pipe while drilling the 17-1/2" surface hole to 2700'. The diverter lines will be vented in two different directions to provide downwind diversion. After running and cementing 13-3/8" 72# L-80 surface casing at 2700', a page 76 blowout preventer {BOPE} consisting of three 13-5/8" 10,O00 psi W.P. rams, a 13-5/8" 10,O00 psi. W.P. annular preventer, and a two-choke manifold will be installed, After installation of the BOPE, it will be thoroughly tested for leaks using diesel fuel. It will be pressured tested and function tested as required in 20 AAC 25.035. This same procedure will also be followed after setting 9-5/8" casing. Automatic and manual monitoring equipment will be installed to detect any abnormal variation in the mud system and drilling parameters. A mud logging unit, manned by experienced personnel, will be in continuous use while drilling, and it will monitor formation pressure, hydrocarbon shows, and loss or gain in the mud pits as well as other downhole conditions. In the event that the well "kicks", the BOPE will be used to shut in the well immediately and confine the pressure within a closed system. The casing program is designed so any anticipated formation pressures can be shut in at the surface without a casing failure. The Company representatives assigned to the drill site will have extensive training, together with actual experience in controlling and killing kicks. These personnel will be further supported by well-trained drilling crews approved by the Company. Pressure resulting from a kick will be circulated out using the balanced bottomhole pressure method, and the well will be restored to its normal operating condition. page 77 In the unlikely event that control procedures are unsuccessful and a blowout does occur, emergency steps must be initiated. This usually involves people, equipment and methods dictated by the circumstances. Very often directional wells are drilled for the purpose of killing or controlling the blowout. In the event of such an emergency one of the many rigs in the North Slope area would be made available for drilling the directional well. 2.7 Procedures for notifying operating personnel, response personnel, and appropriate state and federal agencies are covered in Section 3 and Appendix D of the ABSORB Manual. A copy of the form and reporting guidelines from ABSORB are included here as Figure 2.2 and 2.3. 2.8 A complete inventory of clean up equipment is provided in Section 7 of the ABSORB Manual. 2.9 The use of chemical collectants and chemical dispersants for the use of oil discharge control is thoroughly covered in Section $ of the ABSORB Manual. 2.10 Response times to a spill will depend on the source and severity of the spill and many other conditions that may exist at the time of the spill. Small spills can be reacted to immediately, then contained and cleaned up with personnel and equipment at the well site. Other spills may require the obtaining of additional personnel and equipment.

Attention has been focused on those environmental conditions that will have an impact on the drilling of an exploratory well near Cross Island in the 1982 and 1983 drilling season. Consideration has been given to site description; ice, oceanographic, adn meteorological conditions affecting site preparation, mobilization, drill, and demobilization; and the biological impact of drilling activities on wildlife and fish in the area. An attempt has been made to present the discussion in a format that can be directly used in Tenneco's operational plan. SITE DESCRIPTION General Cross Island is a member of the Midway Islands group located about 18 miles north of Prudhoe Bay (Figure 1). The island is semicircular in plan, about 2 miles long, and 1,100 feet at its widest point, maximum elevations on the island are 7 to 8 feet. The island is primarily composed of silt and sand, and coarse gravels may be found at higher elevations. There are a few patches of sparse vegetation on the island (Gavin, 1976). During the summer the island may be subjected to waves and surge caused by severe summer storms (Reinmitz and Maurer, 1979). In winter large ice pile-ups have been observed on the island's northern beaches (Kovacs and Sodhi, 1979). It should also be noted that Cross Island has been identified as an important bird breeding and molting site during the summer (Divocky, 1978; and Gavin, 1976). 71°00~ 70°',30, 70000* II 1,3 / ..... ,4 i.'i · I I I 150° 149° 148° 147° 166° Fi 9ure ] Geotechnical Considerations Cross .Island is a recent constructional accumulation (lag deposit) of sand and gravel entirely derived from the Pleistocene Flaxman Formation (consolidated marine sandy silt containing dropstones of Canadian origin). The island appears to be migrating southward en masse at rates of 12 to 24 feet per year. The older parts of the island, covered by vegetation, are underlain by ice-bonded permafrost at depths of about 6 feet. Most of the island does not have permafrost near the surface, that is, within 30 feet (Rogers and Morack, 1978). Based on a borehole obtained just northeast of Cross Island by Harding-Lawson Associates (1979), relict permafrost is expected about 60 to 70 feet below the island surface. Numerous mounds, up to 5 feet high, extend as much as 100 feet inland from the northern beach. These mounds were formed during previous ice pile-up and ride-up events (Kovacs and Sodhi, 1979). Problems may be encountered with gas hydrates during drilling. Katz (1971) has indicated that gas hydrates may be present at depths between 1900 and 3400 feet in the Prudhoe Bay area. The sediment source for Cross Island is no longer evident. The' island is a lag deposit and is regarded as being irreplaceable by arctic geologists. Removal of gravel from the island would perturb the local oceanographic and biological regime. Summer Conditions During August and September the area around Cross Island is usually ice free and the island may be subjected to waves and surge caused by easterly and westerly storms. Easterly storms (winds greater than 25 knots) typically last for 3 to 5 days. They result in offshore ice movement and negative surge. The low water levels often ground boats and barges in shallow water areas. Westerly storms are usually accompanied by strong west to northwest winds (greater than 25 knots) and usually last 2 to 3 days. These storms result in positive surge and must be considered in the design height of drilling platforms to be used in the summer. The average frequency of easterly and westerly storms by month is given in Table 1. Waves during the summer are generally less than 2 feet high and rarely greater than 8 feet in height (Brower and others, 1977). Extreme statistics on oceanographic conditions have been reported by Heideman (1979). Some results from two hindcast studies performed for a 30-foot water depth site in Stefansson Sound are given in Table 2. The Splash II model was used to hindcast storm surges and Bretschneider's shallow-water wave generation theory was used to calculate the height of storm wages. It is expected that the storm surge levels would be slightly less for Cross Island and that the storm waves would be slightly higher. The estimated 100-year storm surge level agrees favorably with observed results of the 1970 North Slope storm reported by Reimnitz and Maurer (1979). Wood carvings from a cross erected on Cross Island in 1889 were washed away during that storm. Winter Conditions Freezeup along the North Slope takes place in late September or early October. By the middle of October the ice is usually continuous inside the barrier islands and by early November the ice extends seaward of the barrier island to the pack. During freezeup the thin ice may be susceptible to large movements, however, as the ice thickens it becomes more stable. Over ice transport-inside the barrier islands is generally safe by late December when the sheet ice is about 3 feet thick. The ice remains safe for travel in Stefansson Sound until the rivers overflow the sea ice in late May. Immediately north of Cross Island the ice may remain dynamic throughout the winter and is usually Table 1 FREQUENCY OF EASTERLY AND WESTERLY STORMS ALONG THE NORTH SLOPE (after Selkregg, 1976) Month Easterly Westerly August 3.3 1'0 September 2.8 1.3 October 1.5 1.0 Table 2 OCEANOGRAPHIC DESIGN CRITERIA FOR A 30-FOOT WATER DEPTH SITE IN STEFANSSON SOUND (after Heideman, 1979) Return Period (Years) Storm Significant Wave Maximum Wave Surge Height Height (Feet) (Feet) (Feet) 25 4.4 12 22 100 6.3 14 27 highly deformed. Breakup takes place in July and by the end of July.the area of interest in usually surrounded by open water. Average dates of significant seasonal fast ice events are given in Table 3. These data were compiled by Barry (1977) from four years (1973-76) of Landsat satellite imagery. In a subsequent study, Barry (1978) reported that river overflooding of the sea ice was first preceded by darkening of the river channels (average date of 22 April). Stringer (1979) has characterized the ice inside the barrier islands as being generally smooth, often formed in place with little or no deformation. Occasionally, the ice is broken while it is still thin and forms a cover of floes surrounded by a matrix of younger broken ice. These small ridges are typically less than 2 feet high (Cox, personal communication) and present little difficulty to surface travel. Even though the ice inside the barrier islands is generally smooth from year to year, it can exhibit significant surface roughness. During 4-9 November 1978 storm ridges up to 13 feet high were formed inside the barrier islands. This storm was then followed by another event which resulted in the formation of some minor pile-ups on the south side of the barrier islands-- (Kovacs and Weeks, 1979). Larger ridges, such as these, are typically isolated and may be avoided through route selection by ice reconnaissance flights. Ice movement inside the barrier islands after November is certainly limited. Ice movements statistics for a site in the middle of Stefansson Sound have been presented by ~<heeler (1979) and are given in Table 4. The data were compiled from three winters of ice movement measurements obtained in the area by petroleum operators. .The maximum observed ice movement or excursion in Stefansson Sound was 14 feet. The maximum measured rate of movement was 5 feet per hour. Estimates of the 25 and 100-year ice movement rate and excursion were also given.

The ice just offshore is usually highly deformed consisting of large shear ridges and dynamic'flaw leads. These ridges have sail heights of several tens of feet and are up to 10 miles long (Kovacs and others, 1976). During March-May 1976, a large multi-year shear ridge was investigated in 45 feet of water just north of Cross Island. Maximum ridge heights were up to 40 feet. This ridge had formed in the fall of 1976 and remained in the area through August 1976 (Kovacs and Weeks, 1976). Similar large features have also been observed off Narwhal Island in 60 feet of water. During a 16-18 March 1979 storm, a grounded ridge 70 feet high and over 1000 feet long was formed. Half a mile of ice movement was observed to have taken place about 5 miles to the west of this site (displaced seismic lines). Ice movements in water depths less than 60 feet just north of Cross Island have been described by Agerton and Kreider (1979). During the 1976-77 winter, movements in excess of 150 feet were measured during January and April storms. Movements measured farther offshore by OCSEAP investigators were even greater (Tucker and others, 1978). Large ice motions can occur any time during the winter north of the barrier islands if the ice sheet is not suitably pinned by large grounded ridges or multi-year ice. Large ice pile-ups also have been observed on the northern beach of Cross Island. In 1974 a large pile-up having a mean height in excess of 20 feet was studied by Kovacs (Kovacs and Sodhi, 1979). The ice blocks in the pile-up were 20 inches thick. Ice just offshore was 21 inches thick indicating that the pile-up had recently formed. 10- Area Wildlife A summ., ary of annual biological events in the Beaufort Sea is presented in Table 5 (from Broad, 1980). Available information indicates that little wildlife will be present on or around Cross Island during the anticipated operations period (15 October through 15 May). The primary residents in t~e area during winter are polar bears and ringed seals. Occasional visitors are arctic foxes and a few bird species (willow ptarmigan, snowy owl a~d common raven). Polar bears and ringed seals reproduce during the winter. Major land denning areas of the polar bear are along the banks of rivers, especially in Cambden Bay. Denning areas in landfast ice are believed to be distributed widely along the Beaufort coast from Jones Island eastward beyond Flaxman Island. Polar bear tracks have been sighted on Cross Island during winter (Gavin, 1976). Ringed seals are present in the landfast ice zone during winter. They are known to be in the area from historical hunting records. The depth beneath the ice adjacent to Cross Island is limited during winter, so it is doubtful that any seals will be present near the drilling site during drilling operations. Several other organisms are present on and around Cross Island during the summer or "non-drilling" season only, and therefore, should pose no restrictions to winter drilling operations. Benthic forms retreat to greater depths with the onset of freezeup to escape crushing by encroaching ice. Plankton is-plentiful during the brief open water period.. ~ost of these organisms are eaten by fish and seals while those that survive overwinter under the ice bear young the following year (Carey, 1978). Birds, primarily common eiders, glaucus and sabine gulls, and arctic terns, nest on Cross Island from June through August. However, they do not occupy the island until the onset of breakup 11 MICROB.

Many birds-- old squaws, red and northern phalaropes, sabine's gulls, snow geese and eiders-huse many of the barrier islands, including Cross Island, for molting and staging prior to their southward migration. All birds, except a few stragglers, are gone from the North Slope by 15 October. Bowhead whales migrate during the proposed non-drilling season. Their north-northeastward movement takes place from May to June primarily in leads offshore in the flaw zone. They migrate west- ward during September and October, generally seaward of the barrier islands (Braham and others, 1978). There is some concern that young bowhead whales, because of their relatively small size, will be able to come near or even inside the barrier islands. However, it is unlikely that they will remain in the area later than October. Area Fish Over 30 species of fish inhabit the nearshore waters along the Alaskan North Slope. Areas of greatest species diversity are the deltas of the large rivers. The species can be classified into three broad categories: (1) freshwater species which reside in rivers; (2) anadromous species, those that tolerate both salt and fresh water and migrate from one to the other during their life cycle; and (3) marine species, those that remain in brackish or marine waters throughout their lives. Three anadromous and two marine species account for most of the fish present in near- shore waters of the Alaskan Beaufort Sea. These are: Anadramous Arctic cisco Least cisco Arctic char Marine Fourhorn sculpin Arctic cod During the summer the anadromous species migrate from the rivers to the nearshore deltaic regions to feed extensively. In general these fish do not migrate far offshore and most are found along the mainland coast or arounu the island perimeters. The reason for this is not known entirely, but the shoreline waters tend to be slightly warmer and less saline that other areas. Little is known about fish overwintering habits. In general, anadromous fish leave the coastal waters and return tooverwinter in deep or spring-fed channels in the deltas of major river mouths. ~resumably marine species migrate to deeper water offshore, though the fourhorn sculpin is known to use the Colville Delta. Arctic cod are known to be present during winter, but their under-ice distribution is unknown (Carey, 1978). Ice surrounUing Cross Island undoubtedly will be grounded, and therefore, it is unlikely that any fish will be present in the vicinity of the proposeU drill site. ICE LOADS AND RIDE-UP During the course of the drilling operation t~e island may be susceptible to large lateral ice loads and ice ride-up caused by movement of the surrounding ice sheet. 14 Ice ride-up is not considered to be a problem after December. Typically, ice Tide-up and pile-up occur during freezeup and breakup when the ice is hi§hly mobile (Kovacs and Sodhi, lg79). After December, the ice around Cross Island has stabilized. Immediately around the island the ice will have frozen to the sea floor to the 3-foot depth contour. Grounded shear ridges north of Cross Island also will pin the ice sheet and protect the island from the pack. The southern and central portions of the island may be protected from riae-up by pile-ups which had formed on the island perimeter during freezeup. An advancing ice sheet would either join against the pile-up or ride-up to the top of the pile and fail. Existing ice push mounds on the beach will increase the sliding resistance of an advancing ice sheet and induce failure. Even though ice push mounds and pile-ups have been observeU on the perimeter of Cross Island, the island has not been over-ridden by ice in the recent past. The USGS survey tower and the 30-year old cabin on the island have never been encroached upon by ice. Drilling operations have also been safely conducted on other natural islands near Prudnoe Bay (Gull, Niakuk, ano Flaxman Islands). Consideration is being given to installing an ice movement station north of Cross Island to warn personnel of any ice motion during the Urilling program. The ice movement monitoring system causes an alarm to sound at the drill site should the ice move greater than a preset amount. 15 ICE ROAD Once the sea ice in Stefansson Sound has reached a safe thickness, the drilling operation will be supplied via an ice road from Prudhoe Bay to Cross Island. The ice road will also De used to demobilize the well in late March and April. An analysis of the "safe ice thickness" is academic for most ice road traffic. North Slope construction firms and contractors have indicated that the ice must be about 3.5 to 4 feet thick before they will operate heavy equipment (25-50 tons) on the ice. Based on the ice thickness data compiled by Schell (1974), this thickness is usually attained by early to late January (Figure 2). Ice stress calculations will be performed for heavy loads (rig and substructure). A safety factor of 3 in these calculations has proved to provide a realistic mar§in of safety. The ice is regarded as being safe for travel until late May when the ice near the coast is flooded by river overflow. Other factors besides the flexural stren§th and ice thickness affect the bearing capacity of the ice sheet. Consideration will be given to vehicle speeds, fatigue, and cracks. Vehicle speeds will De maintaine~ below the critical velocity that results in the formation. 16 Figure 2, BEAUFORT SEA ICE THICKNESS CURVE (after Schell, 1974) 0.0 ~ LO L5 NOV, 0£C, ,lAN. FEB. MA R.

Velocities in excess of the critical velocity can result in increased stresses in the ice sheet and failure. Fatigue due to repeated loading may produce unWanted cracks in the ice. Consideration is being made to make the ice road of sufficient width so that the traveled path can be changed periodically to allow for the recovery of fatigued areas. Wet cracks will be avoided as the bearing capacity of the ice sheet is one-half that of a continuous ice sheet. Factors affecting the bearing capacity of an ice sheet and the use of ice roads have been described adequately by Assur (1961), Gold and others (1958), Gold (1971) Michel (1978), and Nevel (1970). Ice roughness should not present a problem for over-ice transport in Stefansson Sound. Generally, the ice is smooth with low relief. Larger ice features or deformed areas can be avoided by flying an ice reconnaissance prior to route selection. 18 REFERENCES Agerton, D. J. and Kreider, J. R.

Attachment ADDITIONAL COMMENTS ON ICE RIDE-UP Ice ride-up is of great concern to North Slope natives and will certainly be an issue during presentations in Barrow. Ride-up or "Ivu" has been observed by the Inupiat on many occasions in the Barrow area. The advancing ice sheet has damaged structures and taken lives. Natives have reported that even the top of barrier islands have been. sheared off by ice. The most comprehensive work on the nature and occurrance of ride-up is that of Kovacs and Sodhi (1979). As the distribution of this report is limited, a copy is attached for your information and files. The report has been described as "bad news" by Exxon personnel during the Gravel Island Technical Seminar. Kovacs and Sodhi show that ride-up is a common event and that it can take place during the winter even when the ice is in excess of 4 feet thick. A summary of observed ride-up events along the north coast of Alaska is included in Table iA. Ice has also been observed to have ridden- up and on top of 30-foot high bluffs near Barrow. As ride-up events usually last less than one-half hour, little time is available f~r evasive action. Fortunately, the ice stresses associated with ride-up are low, less than 50 psi, and defensive measures may be taken to minimize the risk of ride-up. These include placing sandbags on the beach to resist sliding of the ice sheet; a berm may be constructed around the perimeter of the island to cause jamming of the ice and initiate pile-ups, and a buffer zone may be maintained around the well and camp to accommodate_any ride-up. We may also be warned of such events with.a suitable ice monitoring system. 23 Table lA SUMMARY OF OBSERVED RIDE-UP EVENTS ALONG THE NORTH COAST OF ALASKA (Compiled from Kovacs and Sodhi, 1979) Location Barrow Barrow Barrow Flax~an Is.

Attachment ADDITIONAL COMMENTS ON THE ICE ROAD To insure safe utilization of the ice road the following should be considered: 1. Placement of stakes at 300-foot intervals along the road .and several emergency warm-up huts. This will allow travel along the road during poor visibility periods and shelter during white-out conditions. 2. Determine critical velocity for vehicles as a function of ice thickness and water depth. Place speed limit signs along ice road. 3. Snow removal and control should receive adequate attention. Snow banks along the sides of an ice road may overload the ice and cause the formation of longitudinal cracks. It is standard practice to clear the snow to a width of at least 150 feet and keep the snow bank height less than two-thirds the ice thickness. It is also recommended to keep a few inches of compacted snow on the ice for better traction. The thin snow layer will reduce thermal cracking and internal deterioration due to the absorbtion of solar radiation. 4. Advantage should be taken of the experience gained during the use of the Reindeer Island ice road (RIST well). 5. Safety procedures should be defined and given to personnel using the ice road.
