Jim Regg AOGCC piD#- I'6Z -111 5CANNED DEC 1 6 2005 1 of 1 12/5/20055:10 PM Memorandum To: State of Alaska Oil and Gas Conservation Commission Cancelled or Expired Permit Action EXAMPLE: Point McIntyre P2-36AXX API# 029-22801-95 This memo will remain at the from of the subject well file. Our adopted conventions for assigning APl numbers, permit numbers and well names did not specifically address expired or c~ncelled permits. This omission has caused some inconsistencies in the treatment of these kinds of applications for permit to drill. Operators have asked us to adopt formal procedures for this class of permit application in order to prevent future database disparities. If a permit expires or is cancelled by an operator, the permit number of the subject permit will remain unchanged. The APl number and in some instances the well name reflect the number of preexisting reddlls and or multilaterals in a well. In order to prevent confusing a cancelled or expired permit with an active well or multilateral these case sensitive well identifiers will be changed for expired and cancelled applications for permits to ddil. The AP! number for this cancelled or expired permit is modified so the eleven and twelfth digits is 95. The well name for a cancelled or expired permit is modified with an appended xx. These procedures are an addendum to the APl numbering methods described in AOGCC staff memorandum "Multi-lateral (weilbore segment) Drilling Permit Procedures, revised December 29, 1995. AOGCC database has been changed to reflect these changes to this permit. e McMains - ~ Statistical Technician STATE Of ALASKA ALASKA ~iL AND GAS CONSERVATION C0,.,-MISSION SUNDRY NOTICES AND REPORTS ON WELLS 1.

McARTHUR RIVER #1 SECTION 6 LO 82-141 Gentlemen: This is an amendement to our Plan of Operations dated June 10, 1982. Instead of using the Ocean Tempest shipshape rig, Mobil will use the Pennrod 96, a jack-up type drilling rig. The attached drawing of the Pennrodo96 rig will replace the Ocean Tempest drawings. All other attachments on our June 10, 1982, Plan of Operations will not be changed. The changes within our plan are as follows: OPERATIONAL PLA~S The target date to move in the Pennrod 96 is August 10, 1982. Phillips is currently using this rig to drill a well in the Cook Inlet. The S. McArthur River Unit #1 will be drilled 950' from the north line and 600' from the west line.of Section 6-T7N-R13W. Drilling operations will last approximately 70 days. The Pennrod 96 is capable of drilling in 250 foot waters. The mean low water depth at our location is 180 feet. The Jack-up rig configuration is shown in the attached drawing. The Pennrod 96 has living quarters for seventy-two (72) people. The jack-up rig also has equipment and methods for handling food, water, filtration and treatment. Approval for these items is being sought by Mobil and Pennrod through the appropriate state agencies. State of Alaska July 7, 1982 Page 2 WATER SUPPLY No change except the Pennrod 96 has 3200 barrels of fresh water storage capacity for the mud system, and can produce up to 15,000 gallons per day of potable water. WASTE WATER DISPOSAL Sanitary wastes from the rig will be processed through the Pennrod's Red Fox sewage treatment plant before being discharged-overboard. All wastes will be discharged in accordance with appropriate regulations. SOLID WASTE DISPOSAL No change. FUEL STORAGE Tanks for diesel fuel used for drilling operations have a 2,565 barrel capacity. Diesel fuel drawn from a 47 barrel day tank is used to power three 1050 KW generators. AIRCRAFT OPERATIONS No change except the Pennrod 96 has a 70 foot diameter heliport. DISPOSAL OF EXCESS WASTE FLUIDS No change except the Pennrod's active mud tank capacity is 1226 barrels and the reserve tank capacity is 426 barrels. DISPOSAL BY BURNING No change except should gaseous hydrocarbons be encountered and the necessity of flaring occur, Mobil will make application to the Department of Environmental Conservation for the apPropriate permits.

McARTHUR RIVER #1 SECTION 6 Gentlemen: The following is submitted as our plan of operation to drill an exploratory well. A shipshape rig (drill ship) will be used to drill one 10,000 foot well in Section 6-T7N-R13W in Cook Inlet. In addition to this plan for which approval is requested, we have filed with the Corps of Engineers for a permit to locate a drilling rig in the Cook Inlet on the lease. An application is being prepared to file for a drilling permit from the Alaska Oil and Gas Conservation Commission. An NPDES permit has also been applied for. OPERATIONAL PLANS As soon as all necessary approvals are obtained (target date is August 1, 1982) we plan to move in the Ocean Tempest drillship, owned by Odeco. It will be anchored 950' from the north line and 600' from the west line of Section 6-T7N- RI3W. The drillship will be moved from Galveston Bay, Texas, to the Cook Inlet. Drilling 'operations will last approximately 70 days. The Ocean Tempest is capable of drilling in 600 foot waters. The mean low water depth at our location is 180 feet. The generaldrillship configuration, anchoring pattern, and well site location are shown in the attached drawings. The Ocean Tempest drillship has living quarters for seventy (70) people. The drillship also has equipment and methods for handling food, water filtration and treatment, waste disposal, and sewage treatment. Approval for these items is being sought through the appropriate · state agencies by Mobil. State of Alaska June 10, 1982 Page Two WATER SUPPLY Fresh water for the mud system will be obtained from on shore. The drillship has a capacity of 16,668 barrels for this water. Domestic water will be hauled from shore or supplied from a distillation plant on board. The Ocean Tempest has two tanks for potable water, with a total capacity of 1909 barrels. Samples of the domestic water supply will be submitted weekly, or as requested, to a state designated laboratory. WASTE WATER DISPOSAL All other waste water and sanitary wastes from the ship will be processed through a Red Fox sewage treatment plant onboard the Ocean Tempest. This treated effluent will also be discharged overboard in accordance with the NPDES permit. Kitchen and shower water will be disposed of overboard in accordance with the NPDES permit. SOLID WASTE DISPOSAL Solid waste material will be hauled to shore to an authorized sanitary landfill. FUEL STORAGE Fuel for drilling operations is stored in tanks on the drillship having a capacity of 5,136 barrels. The two cranes are run by diesel engines. The drawworks, rotary and mud pumps are electrically driven. Electricity is provided by three 1500 KW generators. AIRCRAFT OPERATIONS No fixed wing aircraft operations will be used. Most of the support travel will be by. helicopter, or by boat, as necessary. The Ocean Tempest drillship has a 60' by 60' h~liport located on the aft end of the ship. DISPOSAL OF EXCESS WASTE FLUIDS Drill stem tests may be run to evaluate oil sands encountered. Crude oil produced during each test will be reinjected. Upon completion of the well, the excess drilling fluid will remain in the mud tanks. (The active mud tank capacity on the Ocean Tempest is 1200 barrels. Reserve mud tank capacity is 800 barrels.) This mud will be disposed of over- board in accordance with the NPDES permit or hauled to an authorized disposal site. State of Al~aska June 10, 1982 Page Three / - DISPOSAL BY BURNING During testing operations on the well, produced hydrocarbons will be run through a gas-oil separator with oil diverted to tanks for holding prior to re-injection. For safety reasons, we request approval to burn all associated gas.' A flare permit will be applied for. This well is being drilled for logging and testing information only. Once these operations are completed, the well will be plugged in compliance with Alaska Oil and Gas Conservation Commission regulations. Please contact Suhail.Nabi, Drilling Engineer (Phone (303) 572-2669), or Gary Hoffman, Regulatory Engineer (Phone (303) 572-2169) if you have any questions or require additional information.

If fbbil elects to drill a test w~ll, it sh~ll commence, or cause to be ~ed, the aco_ml drilling of the test well on Subject Lands on or before ~_~gust 1, 1982. %he test well shall be drilled in a proper and wo~ike manner, either to a dapth at which oil or gas is encountered in paying quantities, or to a dapth of 13,000 feet or 300 feet into the Hmnlock formation, whichever first occurs. In th~ event mechanic~] difficulties or other comd~tions are encountered before the test well reaches the above re~,{red dapth which render further drilling in said well urmrarranted or impracticable, ~bbil may, within thirty (30) days after aban- ~t of such well, c~mm~n~e the drilling' of a substitute well on Subject Lands, and thereafter prosecute the drilling thereof with dura H~I igenme to the above specified depth. Mmbil ~m_y drill any m~er of such substitute wells to the above specified d~pth, provided not more than thirty (30) days elapse betw%~ thru aban- dornm~t of one suah well and the coDln~nc~t of the nmxt. Any substitute w~ll which Fbbil so elects to drill sh~ 11 be considared and treated as tha above test well for all purposes hereof. If ~bbil is unsuccessful in reaching th~ atxr~ required dePth in the test w~ll or any substitute well above dascribed, it may then elect to plug and abandon the well, and terminate this Agre~m~n~ t without ~mrning an assignment from Fmlhouty. 4. ASSI~. Primr to the ~em~nt of the test w~ll, Mobil sbm]_l be de,mind to own all the work~ interest in the well, and 'if ~Mobil completes the test w~ll as a w~ll capable of producing oil and ~ in comnmrcial c~ntities, Ba]bouty sb~]l execute and deliver to Mobil an assig~m=nt conveying one hundred percent (100%) of B~]bouty's ~rking interest within the spacing unit for such well and an ur~~ sixty percent (60~/o) of Halbouty's working interest in the r~air~mr of the Subject Imnds. ~he above asset shall be subject to Halbouty reserving a 1/16th overriding roymlty in the well and to the reservations set forth in Paragraph 5 hereof. 5.

SYSTEMS DESCRIPTION , , ill mmmm Di. ving Vessel: The vessel used was .the M/V Shamrock, a 70' x 28, .diving:' vessel. The Vessel incOrporates a decompression. chamber, surface supply compressor, and diver communication system. The ve'~sel is powered by two GMC 6-71 Diesels. Positionin~ System: A Motorola Mini-Ranger IV W~s used t~'* position the diver's inspection. The system was configured in the 40-mile mode and was configured with two transponders de- ployed at known survey control locations on shore. · Depth Sounding: A Raytheon DE719B Fathometer was aboard for' Confirmation of water depths. ' , ,. FIELD OPERATIONS Navigation system transponders were mobilized to Kenai Monday., October 19, 1981 by John Epps and Mel Saunders. The transponders Were deployed on the control locations October'20, anticipating that the dive vessel would depart 'Rig Tenders · Dock-that day. High winds with the consequent rough sea Conditions, however, forced postponement of the survey. Epps and Saunders then returned to Anchorage to await a break in the weather. -- High winds, and rough sea conditions persisted until Monday, October.26. BEP personnel and divers attempted to fly from Anchorage 't'o Kenai' early Monday. The Kenai airport was closed, however, by heavy fog. The Kenai airport was reopened Monday afternoon, and the crew flew to Kenai so that they would be on site for diving Tuesday. The diving survey proceeded as planned on Tuesday, October 27 and resulted in a bottom sample and diver's description of bottom conditions. .' 'Pag.e 3 · . SURVEY RESULTS A fift¥-po, und sample of the sea floor at the Wildcat #1 first choice location was obtained. The diver then accomplished a bottom survey or-.the area.as follows: Traveled South 100 feet Returned directly to down line at location Traveled West 75' feet · Returned directly to down line at location Traveled East about 50 feet Returned' directly ~o down line at location Current became too great--ended di~e The diver had no visibility on the sea floor because of the :high. parttculat'~ content in Cook Inlet water. All descrip- tions are by feel. The entire area surveyed can be'characterized as follows: Top' layer: Stationary. boulders averaging ~ foot .to 1~ feet in diameter ~ Second layer: Cobbles (fist size rocks) Third layer: Pea gravel and ~coarse sand ..... around boulders The'~diver. dug a test' hole at the well location and encountered hard pan at. 8''~ to 1'. Occasional larger. ~°ulders were encoun- - . tered, 'the largest being 5' in diameter. The diver describ'ed . several "flat" or tabular rocks. These are probably broken from the exposed'" strata 'at' nearby bedrock outcrops. · Lewis John Epps, Partner HOI,~.cIIHOSH(I HOO~IaI VHS ~ ~ HHAI([ &O ~HI(IttOOHtt.

Very truly yours, smh Attachment PHASE II OF SITE SURVEY South McArthur River Prospect, Cook Inlet, Alaska for MOBIL Oil CORPORATION by BESSE, EPPS & POTTS PROJECT DESCRIPTION ~ PHASE II This presentation is a detailed site survey of two Wildcat drilling locations within the South McArthur River 'Prospect. This is the second of three phases for the drill site investigation. The Phase I survey report, bathymetry of the entire prospect and current measurements, is inCluded as Enclosure I. Phase III is a diver investigation of the drill site for Wildcat~ #1 and is cUrrentlY in progress. The two drill sites surveyed during Phase II are the following: WildCat No. t-~ ~- S6'T7N-R13W SM 600'FWL, gSO'FNL Wil'dcat No. 2 S31'-T8N-R13W SM- 800'FEL, 1400'FNL The areas surveyed are 2000 foot strips oriented E - W and centered on each of the proposed Wildcat locations. The specific objectives of Phase II are to provide detailed site bathymetry and geophysical data for these locations. Woodward-Clyde Consultants was contracted to provide a sub- bottom profiling system and interpretation for these sites. This report includes a discussion of survey systems, field operations, and survey results. The. following items are attached: Figure l: Wildcat #1 Bathymetry Map Figure~ 2: Wildcat #2 Bathymetry Map Enclosure 1: Phase I Survey Report Enclosure 2: Geophysical Report SURVEY SYSTEMS .Navigation: A.Motorola Mini-Ranger IV with track line indicator was used for navigation and positioning. This system is configured in the forty-mile mode and was deployed with two transponders. The' Mini- Page 2 : Ranger IV is a multi-range line-of-sight positioning system that computes location by trilateration. As configured for this survey, the Mini-Ranger IV measUred distances from two known control stations on shore to the survey vessel. System accuracy is +3 meters for each range. Depth. Sounding: A Raytheon DE 719 B Fathometer was used for depth sounding. This model Fathometer has a precision of ±~% ±l ft. and a least read of 2 feet in the configuration used for the survey. Side Scan Sonar: A Klein Model 521 Side Scan Sonar system was used for the survey. This survey tool is used to identify changes in sea floor texture and objects on the bottom such as boulders and rock outcrops. Subbottom Profiling S~,stem: An EG&G Uniboom system was used to pro- . vide information about the strata underlying the inlet floor. A Woodward- Clyde Mini-SParker was also present on the survey for use if the Uniboom did not provide adequate penetration but was not used. The Uniboom system components used On this survey are EPC 4100 Recorder, EG&G 231/232 Power Supply and Trigger Capacitor Bank, Uniboom Sound Source, and 265 Hydrophone String. The 'resolution' of this system as deployed was 2-3 feet and the penetration was'~lO0-200 feet. FIELD OPEF~ATIONS , The field survey for Phase II was mobilized September 30, 1981. The field survey 'was completed October 6, 1981, and the equipment was demobilized on October 7, 1981. The field survey was conducted by John Epps, Mel Saunders, Stanley Johnson', and Robert Beer. The vessel used was the O/S Endeavor, a 60-foot tug. The survey was conducted during 12 to 16 hour daily shifts. Accom- modations and board for the survey crew were obtained in Kenai, Alaska. ! Page 3 OCtober 4 and 5 were standby days because of high winds. The survey crew checked and' interPreted survey records on these days. ' The transponder.'locati.ons for the navigation system are accessible only by' helicopter. A local Kenai, Alaska firm provided this service. SURVEY RESULTS Topographic and geological features are.shown graphically on Figures 1 and 2 and on the maps and plates of Enclosure 2. No geological faults were observed nor were any occurrences of shallow concentrated .natural gas. Both sites are typified by exposed or shallo, wly covered bedrock of the Kenai formation. The preferred location for .Wildcat #1 lays on a 7% slope perpendicular to the current direct.ion. This slope, considering the tide currents in this area, may be a significant factor in determining the lateral stability of the drilling rig. ENCLOSURE 1 PHASE I SURV£Y REPORT PHASE I OF SITE SURVEY- South McArthur River Prospect, Cook Inlet, Alaska for MOBIL OIL :CORPORATION by -BESSE, EPPS & POTTS PROJECT DESCRIPTION, Mobil Oil Corporation authorized Besse, Epps & Ports to condUct a site survey of the South McArthur River Prospect in Cook Inlet, Alaska. .The survey is in preparation for a drilling program during 1982. During discussions with Mobi. 1 Oil personnel the decision was made to conduct the survey in two phases. The first phase'is an overall area survey including ail of Sections 32, 31, 36, I and 6 and the soUth quarter of Sections 29', 30, and 25. The second phase is a detailed survey of drilling sites selected after the completion of Phase I. The Phase'l Survey was to obtain bathymetry, current measure- ments, and bottom samples. The purpose of Phase I is to provide information'for the selection of drilling sites and selection of a drilling vehicle '(floater vs jack-up rig). Water depths and bottom conditions are surveyed over a sufficient area to design an anchor configuration should a floating drill ship be selected. Phase I 'was conducted aboard a 24-foot vessel With the folloW~ng systems aboard: Motorola Mini-Ranger for positioning Klein Side Scan Sonar Raytheon DE-719 Fathometer General Oceanics Flow Meter System Sediment Samplers Page Personnel and equipment were mobilized to Kenai, Alaska, August 20, 1981, and demobilized after completion of the Phase I field survey, August 29, 1981. The Phase II Surv. ey is to provide detailed information of the drill sites selected after Phase I. High resolution and medium resolution accoustic profiling systems will be used to detect any Shallow faul.ts-or shallow gas-charged sediments. Side Scan Sonar and a fathometer will be used for a high resolution · survey in the immediate drill site area and to confirm possible gas seeps detected with the accoustic profiling systems. A magnetometer Should-be included in Phase II only if Mobil· has a specific requirement. Upper Cook Inlet has a high magnetic gradient and magnetometer surveys are generally not-very productive. Sed- iment '~ampling and/or coring should be conducted during. Phase II. Our past exPeri~ence has been 'that the most rigorous requirements for'amount~ and type of sampling have been determined by the companies insuring the drilling rig. Phase II will require a larger survey vessel than was used during Phase I and will be a more cOstly survey. If sediment Coring or a. sophisticated sampling program is selected we recommend demobilizing all of the survey systems except positioning and fathometer. BATHYMETRY The survey map generated during Phase I is enclosed. The map shows the section' boundaries making up the prospect and the five . · Page 3 ; bottom hole location preferences for Wildcat #1 and WildCat #2. water depths are shown as~twenty-foot contour lines and spot elev- ations below mean lower low water. The highest predicted annual high water above this datum~is about twenty-five feet. The inlet floor in this area is covered with many boulders. The location and ~size of some of the larger 5oulders were reduced from the side scan sonar records and are shown on the surveY map. These boulders.represent less than l%'Of the boulders in the prospect and were chosen_to represent the largest boulders in the area. Attempts atbottom sampling and anchoring the 'survey vessel for current sampling.indicate that theb0ulders are bedded in cobbles or coarse gravel. No bottom samples were obtained as confirma ti on, The survey vessel has a gross weight of about 5,000 pounds and has a smooth planning hull. A 40-pound Danforth-type anchor was used to anchor the Vessel for current measurements on August 27, 1981. This anchor is recommended for vessels with.more than four times the gross weight of the survey vessel. The anchor broke loose and was destroyed at.14:15 at an observed current speed of 5.9 knots. The condition of the surface of the metal of the anchor indicates that it was dragged through coarse gravel or boulders. A picture of this anchor .is enclosed. The condition of the metal ~urface of the bottom sampler after sampling attempts also indicated that it had been dragged through Coarse gravel or boulders. Page N© evidence was found on the side scan sonar records to indicate rapidmo~ement of the boulders on the inlet bottom. We have observed large boulders remaining in the same location rela- tive to pipelines in Cook Inlet over a period of several years. · · DATUM ANDITIDE REDUCTION Datum for water depths is the National Oceanic and Atmos- pheric Administration determined mean lower low water. This datum is determined by N.O.A.A. from several tide stations located in Cook Inlet. N,O.'A,A. pUblishes tide tables for several locations in COok Inlet and corrections to be applied to these tables for a number~of Other locations. The tide correction for this survey was obtained by prOportion- ing 5/9 frOm the N.O.A.A. correction at Drift River to the N.O.A.A. correction at North FOrelands. CURRENT MEASUREMENTS Current measurements, were obtained by anchoring the survey vessel and deploying a General Oceanics Flowmeter. The flowmeter system is direct reading and was manually recorded at five-minute intervals during the measurement periods. The flowmeter sensor was deployed thirty feet from the Water surface on a line and fifty pound streamlined lead weight~ The reaction of the' line and weight to the current lifted the sensor to about one-half its slack water depth during Periods of maximum current. A table of the recorded currents is enclosed. Page 5 SAMPLING Bottom sampling was attempted at eight locations during the survey, six of which are shown on the accompanying survey map. The only sample obtained was from several m~les outside the survey area and was obtained as a check of the sampling method. The sampler used is effective with cohesive clay and silt size material and with sand and gravel with grain size to about one inch. The sampler was battered during the sampling-attempts and appears to have been d~agged through cobbles or boulders. ANCHORING CONDITIONS OBSERVED The survey vessel was anchored while taking current measure- ments, August 27th and 28th. On August 27th a forty-pound Danforth type anchor with twenty feet of three-eighth inch chain was used. This anchor is recommended for a vessel of several times the gross weight of the twenty-four-foot, 5,000 pound survey vessel. The anchor failed at 14:15 and was destroyed. A picture is enclosed. The tYpe of failure,' as shown in the picture, indicates that the anchor was set in boulders. On August 28th the survey vessel was anchored with two piggy- backed standard stocked anchors weighing twenty-five pounds each. The anchors were connected with·twenty feet of chain and led by fifteen feet of three-eighth inch chain. This ground tackle anchored the survey vessel in a reasonable manner although larger anchors would have been preferred if obtainable. The anchors Page' 6 were not reCovered.

The objective of the survey is to provide detailed information at two proposed drilling locations. The two proposed drill sites were selected following a regional investigation covering approximately six square miles by Besse, Epps & Ports in August, 1981. This report documents the field operations, data reduction and mapping procedures, and the results of the~ geophysical study of the two proposed drill sites. 1.2 Scope of Work The two sites investigated during this study are located approximately 2 to 3 miles east of West Forelands, CoOk Inlet, Alaska (Figure 1.1). Approximately 23 nautical miles of high-resolution seismic reflection data were obtained during the field operations. Survey lines were run on a 150 metre spacing in both a north-south and an east-west direction. Precision navigation, bathymetry, side scan sonar, and seismic reflection data were obtained simultaneously along each survey line. 1.3 ~eport Section 2 of this report discusses the field operations, the navigation system utilized for offshore positioning, and the geophysical systems used for the data collection. The geophysical data and the reduction and interpretational procedures used to produce the final map and geologic cross-sections are described in Section 3. Section 4 discusses the site geology and the survey results, I' I ' '! 1 Scale in Statute Miles .'~ ·' ~/¢'c~ ~°~e/~~'~ .

II TANT,~, 1-3 Daily operations logs, geophysical systems logs, and detailed specifications for the geophysical system used on this survey are presented in the Appendices. 2.0 FIELD OPERATIONS 2.1 Offshore Geophysical Survey Field operations for the offshore geophysical survey began with the mobilization of the survey equipment aboard the survey vessel the M/V Endeavor in Anchorage, Alaska on 30 September 1981. Mobilization was completed and the vessel departed for Nikishka the same day. Survey operations commenced 1 October 1981 on a 12 hour/day basis following an at-sea checkout of the geophysical equipment. The survey was completed on 6 October 1981, and the vessel demobilized in Anchorage the following day. Throughout the survey period, the seas were moderate and the weather fair to poor, resulting in several delays in the work schedule. No significant delays were experienced due to survey equipment problems. Documentation of all pertinent survey events is contained in the daily~ operations logs in Appen- dix A. Personnel involved in the field operations included: a Woodward-Clyde Consultants marine geophysicist; the Besse, Epps & Ports survey crew consisting of a navigator and two marine surveyors; and the crew of the M/V Endeavor. The survey program consisted of a ~detailed investigation of two proposed drill sites. Approximately 23 nautical miles of survey data were obtained in an X-Y grid at each area. A 150-metre line spacing was utilized to provide the required high-density data coverage at each site. The field operations included simultaneous data collection from the following systems: Motorola Mini-Ranger Electronic Navigation System Raytheon DE-719 Precision Survey Fathometer 2-2 o Klein Model-511 Side Scan Sonar System o EG&G UNIBOOM High Resolution Seismic Reflection Profiling System The layout of the equipment aboard the survey vessel M/V Endeavor is shown in Figure 2.1. Details of the specific instrument settings are given in the Geophysical Systems Logs in Appendix B. Manufacturers' specifications for the geophysical instrumentation utilized during this survey are provided in Appendix C. 2.2 Navigation Offshore positioning was provided by Besse, Epps &Potts of Anchorage,. Alaska, who utilized a Motorola Mini-Ranger IV electronic navigation system. The Motorola Mini-Ranger IV is a short range (approximately 20 nautical miles) line of sight, range-range navigation system. The basic system consists of a range processor and control/display unit, receiver-transmitter, and an omni- directional antenna installed on the boat. Two or more reference transponders are located at pre-surveyed points on shore. The measured ranges to the two transponders are displayed, in metres, on the range console onboard ship. The accuracy of the ranges is +2 metres at 20 nautical miles. The actual accuracy of the system is a function of the ranges and the angle of intersection of the two range lines. Complete specifications for the Mini-Ranger system are given in Appendix C. 2.3 Geophysical . Systems An EG&G UNIBOOM high resolution subbottom profiling system was used to provide information on the nature and geometry of the subbottom soil and bedroCk horizons, to detect subsurface faults, and to identify areas of concentrated 2'-3 · UNIBOOM ATAMARAN VAR ABLE SIDESCAN TOWFISH VESSEL: M/V ENDEAVOR LENGTH: 60 FEET BEAM: 16 FEET DRAFT: 7 FEET NAVIGATION ANTENNA FATHOMETER TRANSDUCER HYDROPHONE ARRAY Project: COOK INLET GEOPHYSICS Project No. 414621 GEOPHYSICAL SURVEY VESSEL EQUIPMENT LAYOUT Fig. 2.1 2-4 ! shallow gas. A precision survey fathometer and a~ side scan sonar system, which were provided by Besse, EPps &,Potts, were also utilized during this investigation. The EG&G UNIBOOM system consists of an EG&G 231/232 power source, a UNIBOOM plate mounted on a towed catamaran, a receiving hydrophone, and an EPC Model 4100 seismic record- er. The UNIBOOM sound source is an electromechanical boomer plate which generates a broadband acoustic pressure pulse with a frequency spectrum from 400 Hz to 8 kHz. Complete technical specifications for this system are given in Appendix C. The resulting seismic records generated by the subbottom profiling system are s~milar to a geologic cross-section except that the vertical axis represents the two way travel time of the reflected seismic signal rather than a true depth. Mapping of the data requires corrections for~ the layback of the system from the positioning antenna as illustrated in .Figure 2.1 and conversion of the reflection times to depths using a known or assumed .value for the velocity of sound in the sediments. 3.0 DATA REDUCTION AND MAPPING 3.1 Shiptrack and Shotpoint Locations A project base map was prepared at a scale of 1:2,400 (1 inch = 200 feet), and includes coordinates in the Alaska State Plane System, Zone 4. Navigation post plots at a scale of 1:2,400 were prepared by .Besse, .Epps &Potts of Anchorage, Alaska. These data were edited and the plots served as the base for the Shiptrack Maps (Figures 3.1 and 3.2). These maps show the final survey track lines and each navigation fix point. 3.2 Isopach and Shallow Structure Map The high resolution subbottom profile data provided structural information down to several hundred feet below the sea bed. The sea bottom sediments in the vicinity of the areas surveyed ranged from areas of rock outcrop with patchy overburden to thick sections of unconsolidated Cobbles and boulders. The thickness of the unconsolidated materials was measured, in miliseconds, and converted to feet using a value of 6,000 feet/second for the velocity of sound in this unit. These values were plotted over the shiptrack maps and contoured in feet to produce an isopach map (Figure 3.3). The geophysical records were also reviewed for evidence of any features which could prove to be geological 'con- straints. Geologic constraints include any natural features or conditions that might adversely affect the safety or success of the proposed project. Such features include surface or shallow faulting, landslides or other evidence of soil instability, irregular or steep bottom topography, buried channels, and gas seeps or shallow zones of gas- charged sediments. 3-2 Structural features that were observed on the UNIBOOM records are also plotted on this map. This information was limited to the upper four hundred feet or less below the sea floor, the practical limit of penetration of the UNIBOOM system in this area. 3.3 Geologic Cross Section A geologic cross section was prepared for each area along the east-to-west centerline, through the proposed drill site, to illustrate the shallow sediment geometry immed- iately beneath the sea floor. Thickness of the various subbottom horizons was determined from reflection travel times using a value of 6,000 feet/second for the velocity of sound in the unconsolidated materials and 12,000 feet/ second for the velocity of sound in the underlying bedrock unit. 4.0 DISCUSSION 4.1 General Geology The Cook Inlet area lies within a structural trough sur- rounded on three sides by high mountain ranges. The flat-lying lowland topography bordering the Inlet is the result of several periods of glaciation and subsequent post-glacial deposition. These lowland areas are underlain by thick glacial deposits which overlie a bedrock complex of the Kenai Group, which is Tertiary in age. The bottom sediments foUnd in Cook Inlet are primarily derived from the reworking of glacial deposits and portions of the Kenai Group. Additional sediments are supplied from onshore sources by inflowing streams. During periods of onshore flooding and high seasonal runoff, these sediments often- times consist of gravel and cobble-sized material. During normal flow, the streams deliver sand, silt, and clay-sized material. Sediments in the Inlet range from suspended glacial silt and clay to massive boulders. Clay deposits are most common in the southern Cook Inlet area and are most predom- inant in deep water areas. Silt deposits within Cook Inlet are generally confined to the outer edges of the tidal flats or local lacustrine deposits within the glacial materials. Sand or mixtures of sand and gravel are gener- ally confined to flat-lying areas. In high energy environ- ments, such as the Forelands area, gravel and cobble deposits predominate. These deposits most likely result from the winnowing of fine-grained material by the high- energy tidal currents. The general area of this investigation is underlain by sedimentary rocks and unconsolidated materials of Tertiary 4-2 to Quaternary ages. The Kenai Formation, which is wide- spread throughout the Cook Inlet Basin, is generally considered bedrock for engineering design purposes. This unit consists of interbedded non-marine claystone, silt- stone, sandstone, conglomerate and coal of Tertiary age. The strata have been gently folded and subsequently eroded forming an irregular surface over which glacial and post- glacial material has been deposited. In portions of the area studied during this investigation, the formation is exposed on the sea floor where it has been scoured clean of overburden. A limited area is covered by a layer of unconsolidated post-glacial deposits, generally sand, gravel, cobbles, and boulders. 4.2 Area No. 1 Area No. 1 is underlain by a bedrock complex considered to be the Kenai Formation. The unit is seismically character- ized by numerous prominent reflectors, which dip steeply toward the west. In the western half of the area surveyed, this unit is overlain by a layer of unconsolidated material varying in thickness up to a maximum of approximately 32-35 feet. The eastern half is characterized by outcropping reflectors, and could possibly be covered in areas with a thin veneer of unconsolidated material (Figure 3.3). No evidence of shallow faulting or gas-charged sediments' was observed at this site. An east-west cross section through the proposed site is shown on Figure 3.4. 4.3 Area No. 2 Area No. 2 is underlain by a bedrock complex considered to be the'Kenai Formation. The unit is seismically character- ized by numerous prominent reflectors, which dip toward the west. Only small isolated patches of unconsolidatd over- burden occur throughout the area, generally less than 5 4-3 feet in thickness, but locally ranging up to 10 feet thick. Only an occasional outcropping reflector was noted. No evidence of shallow faulting or gas-charged sediments was observed at this site. An east-west cross section through the proposed site is shown on Figure 3.5. APPENDIX A DAILY OPERATIONS LOGS GEOMARINE FIELD LOG Client B~sse:Epps&Potts Rep, J.

The Sound Source transducers use the Model 231-A Trigger Capacitor Bank, the Model 232-A Power Supply and the Model 233-A Capacitor Bank in various combinations to achieve the desired power levels required. The combination of one Power Sup- ply and one Trigger Capacitor Bank provides 100 to 1000 watt-seconds of energy output. Adding one Ca- pacitor Bank increases the level to 4600 watt-seconds and two Capaci- tor Banks further increases the level to 8000 watt-seconds. Typical sys- tems produce power outputs from 100 watt-seconds to 8000 watt-sec- onds as shown below.

The Model 4100 standard features provide broad flexibility under varying operational conditions. A unique digital direct drive feature enables pre-taped recordings to be reproduced with exact synchronization at a speed equal to or faster than that from which the tapes were made. In the single sweep mode it is possible to.generate records from tapes which incorporate no time channel. Additionally, the left-right/right-left scan feature allows exact record position matching when surveying on a grid pattern, thus providing record overlay analysis capability. The recorder incorporates two independent time references: 1) an internal crystal for the generation of scale lines and control of sweep speed and 2) a panel-mounted Accutron® which is used both as a calibration reference and a survey chronometer ,"" A complete spares complement, packed securely Within ~.~'"'"'~--.%,.~. .,, the case cover, is included with each Model 4100 recorder.

During discussions with Mobil Oil personnel the decision was made to conduct the survey in two phases. The first Phase is an overall area survey including all of Sections 32, 31, 36, 1 and 6 and the south quarter of Sections 29, 30, and 25. .The second phase is a detailed survey of drilling sites selected after the completion of Phase I. The Phase'l Survey was to obtain bathymetry, current measure- ments, and bottom samples. The purpose of Phase I is to prDvide information for the selection of drilling sites and selection of a drilling vehicle '(floater vs jack-up rig). Water depths and bottom conditions are surveyed over a sufficient area to design an anchOr configuration should a floating drill ship be selected. Phase I was conducted aboard a 24-foot vessel With the following systems aboard: Motorola Mini-Ranger for positioning Klein Side Scan Sonar Raytheon DE-719 Fathometer General Oceanics Flow Meter Sediment Samplers ~~'EI V JUL 9 Alaska Oil & Gas £:0~. u .... ',,sion Anchol'age Page 2 personnel and equipment were mobilized to Kenai, Alaska, August 20, 1981, and demobilized after completion of the Phase I field survey, August 29, 1981. The Phase II Sur~ey is t6 provide detailed information of the drill sites selected after Phase I. High resolution and medium resolution accoustic profiling systems will be used to detect any shallow faults or shallow gas-charged sediments. Side Scan Sonar and a fathometer will be used for a high resolution survey in the immediate drill site area and to confirm possible gas seeps detected with the accoustic profiling systems. A magnetometer should be included in Phase II only if Mobil has a specific requirement, uPper Cook Inlet has a high magnetic gradient and magnetometer surveys are generally not-very productive. Sed- iment sampling and/or coring should be conducted during Phase II. Our past experience has been that the most rigorous requirements for amount and type of sampling have been determined by the companies insuring the drilling rig. Phase II will require a larger survey vessel than was used during Phase I and will be a more costly survey. If sediment Coring or a sophisticated sampling program is selected we recommend 'demobilizing all of the survey systems except positioning and fathometer. BATHYMETRY The survey map generated during Phase I is enclosed. The map shows the section boundaries making up the pr~e~~~e five JUL 2 11 1982 Page 3 bottom hole location preferences for Wildcat #1 and Wildcat #2. Water depths are shown as twenty-foot contour lines and spot elev- ations below mean lower low water. The highest predicted annual high water abOve this datum is about twenty-five feet. The inlet floor in this area is covered with many boulders. The location and size of some of the larger ~oulders were reduced from the side scan sonar records and are shown on the survey map. These boulders represent less than 1% of the boulders in the prospect and were chosen to represent the largest boulders in the area. Attempts at bottom sampling and anchoring the survey vessel for current sampling.indicate that the boulders are bedded in cobbles or coarse gravel. No bottom samples were obtained as confirmation. The survey vessel has a gross weight of about 5,000 pounds and has a smooth planning hull. A 40-pound Danforth-type anchor was used 'to anchor the vessel for current measurements on'August 27, 1981. This anchor is recommended for vessels with more than four times the gross weight of the survey vessel. The anchor broke loose and was destroyed at 14:15 at an observed current speed of 5.9 knots. The condition of the surface of the metal of the anchor indicates that it was dragged through Coarse gravel or boulders. A picture of this anchor .is enclosed. The condition of the metal surface of the bottom sampler after sampling attempts · also indicated that it had been dragged'through Coarse gravel or boulders. ~C~V ~ D Page 4 No evidence was found on the side scan sonar records to · indicate rapid movement of the boulders on the inlet bottom. We have observed large boulders remaining in the same location rela- tive to pipelines in Cook Inlet over a period of several years. DATUM AND TIDE REDUCTION Datum for water depths is the National Oceanic and Atmos- pheric Administration determined mean lower low water. This datum is determined by N.O.A.A. from several tide stations located in Cook Inlet. N.O.A.A.'publishes tide tables for several locations in Cook Inlet and corrections to be applied to these tables for a number of other locations. The tide correction for this survey was obtained by proportion- ing 5/9 from the N.O.A.A. correction at Drift River to the N.O.A.A. correction at North Forelands. CURRENT MEASUREMENTS Current measurements Were obtained by anchoring the survey vessel and deploying a General Oceanics Flowmeter. The flowmeter system is direct reading and was manually recorded at fivehminute intervals during the measurement periods. The flowmeter sensor was deployed thirty feet from the water surface on a line and fifty pound streamlined lead weig~t~ The reaction of the line and weight to the current lifted the sensor to about one-half its slack water depth during PeriOds of maximum current. A table of the recorded currents is enclosed. R E C E; V ~ D · Alaska 011 & Gas A~horage Page 5 Bottom .sampling was ath~mpted at eight locations during the survey, six of which are shown on the accompanying survey map. The only sampl~ obtained was from several m~.les outside the survey area and was obtained as a check of the sampling method. The sampler used is effective with cohesive clay and silt size material and with sand and gravel with grain size to about one inch. The sampler was battered during the sampling attempts and appears to have been dragged through cobbles or boulders. ANCHORING CONDITIONS OBSERVED The survey vessel was anchored while taking current measure- ments, August 27th and 28th. On August 27th a forty-pound Danforth type anchor with twenty feet of three-eighth inch chain was used. This anchor is recommended for a vessel of several times the gross weight of the twenty-four-foot, 5,000 pound survey vessel. The anchor failed at 14:15 and was destroyed. A picture is enclosed. The type of failure, as shown in the picture, indicates that the anchor was set in boulders. On August 28th the survey vessel was anchored with two pi'ggy- backed standard stocked anchors weighing twenty-five pounds each. The anchors were connected with twenty feet of chain and led by fifteen feet of three-eighth inch chain. This ground tackle anchored the survey vessel in a reasonable manner although larger anchors would have been preferred if obtainable.

Commission Anchorage t 2.0 FIELD OPEraTIONS 2.1 Offshore GeophYsical sgrvey Field operations for the offshore geophysical survey began with the mobilization of the survey equipment, aboard the survey vessel the M/V Endeavor in 'Anchorage, Alaska on 30 September 1981. Mobilization was completed and the vessel departed for Nikishka the same day. Survey operations Commenced 1 October 1981 on a 12 hour/day basis following an at-sea checkout of the geophysical equipment. The survey was completed on 6 October 1981, and the vessel demobilized in Anchorage the following day. Throughout the survey period, the seas were moderate and the weather fair to poor, resulting in several delays in the work schedule. No significant delays were experienced due to survey equipment problems. Documentation of all pertinent survey events is contained in the daily operations logs in Appen- dix A. Personnel involved in the field operations included: a Woodward-Clyde Consultants marine geophysicist; the Besse, Epps & P°tts survey crew consisting of a navigator and two marine surveyors; and the crew of the M/V Endeavor. The survey program consisted of a detailed investigation of two proposed drill sites. Approximately 23 nautical miles of survey data were obtained in. an X-Y grid at each area. A 150-metre line spacing was utilized to provide the required high-density data coverage at each site.

Manufacturers' specifications for the geophysical instrumentation utilized during this survey are provided in Appendix C. 2.2 Navigation Offshore positioning was provided by Besse, Epps & Potts of Anchorage, Alaska, who utilized a Motorola Mini-Ranger IV electronic navigation system. The Motorola Mini-Ranger IV is a short range (approximately 20 nautical miles) line of sight, range-range navigation system. The basic system consists of a range processor and control/display unit, receiver-transmitter, and an omni- directional antenna installed on the boat. Two or more reference transponders are located at pre-surveyed points on shore. The measured ranges to the two transponders are displayed, in metres, On the range console onboard ship. The accuracy of the ranges is +2 metres at 20 nautical miles. The actual accuracy of the system is a function of the ranges and the angle of intersection of the two range lines. Complete specifications for the Mini-Ranger system are given in Appendix C. 2.3 ..Geophysical Systems An EG&G UNIBOOM high resolution subbottom profiling system was used to provide information on the nature and geometry of the subbottom soil and bedrock horizons, to detect subsurface faults, and to identify areaRE~~~ntrated JUL 2 1 i982 Alaska Oil & ~'~ [;~}ri~, Cu~,~mis~l~n At, thoracic 55' "*"-"- UNIBOOM ATAMARAN VARIABLE 55' SIDESCAN TOWFISH VESSEL: M/V ENDEAVOR LENGTH: 60 FEET BEAM: 16 FEET DRAFT: 7 FEET NAVIGATION ANTENNA FATHOMETER TRANSDUCER ' HYD ROPHOI~I~E JUL 2 ] ]982 Alaska 0il & Gas Cans, Anchorage Project: COOK INLET GEOPHYSICS Project No. 414621 GEOPHYSICAL SURVEY VESSEL Fig. EQUIPMENT LAYOUT 2.1 WOOl)WARD--CLYDE CON~,J LTANT$ 2-4 shallow gas. A precision survey fathometer and a side scan sonar system, which were provided by Besse, Epps & Potts, were also utilized during this investigation. The EG&G UNIBOOM system consists of an EG&G 231/232 power source, a UNIBOOM plate mounted on a towed catamaran, a receiving hydrophone, and an EPc Model 4100 seismic record- er. The U'NIBOOM sound source is an electromechanical boomer plate which generates a broadband acoustic pressure pulse with a frequency spectrum from 400 Hz to 8 kHz. Complete technical specifications for this system are given in Appendix C. The resulting seismic records generated by the subbottom profiling system are similar to a geologic cross-section except that the vertical axis represents the two way travel time of the reflected seismic signal rather than a true depth. Mapping of the data requires corrections for the layback of the system from the positioning antenna as illustrated in Figure 2.1 and conversion of the reflection times to depths using a known or assumed value for the velocity of sound in the sediments.

Navigation post plots at a scale Of 1:2,400 were prepared by Besse, Epps & Ports of Anchorage, Alaska. These data were edited and the plots served as the base for the Shiptrack Maps (Figures 3.1 and 3.2). These maps show the final survey track lines and each navigation fix point. 3.2 .Isopach and Shallow Structure Map The high resolution subbottom profile data provided structural information down to several hundred feet below the sea bed.' The sea bottom sediments in the vicinity of the areas surveyed ranged from areas of rock outcrop with patchy overburden to thick sections of unconsolidated cobbles and boulders. The thickness of the unconsolidated materials was measured, in miliseconds, and converted to feet using a value of 6,000 feet/second for the velocity of sound in this unit. These values were plotted over the shiptrack maps and contoured in feet to produce an isopach map (Figure 3.3). The geophysical records were also reviewed for evidence of any features which could prove to be geological con- straints. Geologic constraints include any natural features or conditions that might adversely' affect the safety or success of the proposed project. Such features include surface or shallow faulting, landslides or other evidence of soil instability, irregular or steep bottom topography, buried channels, and gas seeps or shallow zones of gas- charged sediments. R~EJ~ J U L 2 ]982 3-2 Structural features that were observed on the UNIBOOM records are also plotted on this map. This information was limited to the upper four hundred feet or less below the sea floor, the practical limit of penetration of the UNIBOOM system in this area. 3.3 ~eg!o~ic cross section A geologic cross section was prepared for each area along the east-to-west centerline, through the proposed drill site, to illustrate the shallow sediment geometry immed- iately beneath the sea floor. Thickness of the various subbottom horizons was determined from reflection travel times using a value of 6,000 feet/second for the velocity of sound in the unConsolidated materials and 12,000 feet/ second for the velocity of sound in the underlying bedrock unit. 4.0 DISCUSSION 4.1 General Geology The Cook Inlet area lies within a structural trough sur- rounded on three sides by high mountain ranges. The flat-lying lowland topography bordering the Inlet is the result of several periods of glaciation and subsequent post-glacial deposition. These lowland areas are underlain by thick glacial deposits which overlie a bedrock complex of the Kenai Group,-which is Tertiary in age. The bottom sediments found in Cook Inlet are primarily derived from 'the reworking of glacial deposits and portions of the Kenai Group. Additional Sediments are supplied from onshore sources by inflowing streams. During periods of onshore flooding and high seasonal runoff, these sediments often- times consist of gravel and cobble-sized material. During normal flow, the streams deliver sand, silt, and clay-sized material. Sediments in the Inlet range from suspended glacial silt and clay to massive boulders. Clay deposits are most common in the southern Cook Inlet area and are most predom- inant in deep water areas. Silt deposits within Cook Inlet are generally confined to the Outer edges of the tidal flats or local lacustrine deposits within the glacial materials. Sand or mixtures of sand and gravel are gener- ally confined to flat-lying areas. In high energy environ- ments, such as the Forelands area, gravel and cobble deposits predominate. These deposits most likely result from the winnowing of fine-grained material by the high- energy tidal currents. sedimentary rocks and unconsolidated materials o~~k' U,Tertiary 3UL 2 982 AIlchorage to Quaternary ages. 4-2 The Kenai Formation, which is wide- spread throughout the Cook Inlet Basin, is generally considered bedrock for engineering design purposes. This unit consists of interbedded non-marine claystone, silt- stone, sandstone, conglomerate and coal of Tertiary age. The strata have been gently folded and subsequently eroded forming an irregular surface over which glacial and post- glacial material has been deposited. In portions of the area studied during this investigation, the formation is exposed on the sea floor where it has been scoured clean of overburden. A limited area is covered by a layer of unconsolidated post-glacial deposits, generally sand, gravel, cobbles, and boulders. , 4.2 Area No. 1 Area No. 1 is underlain by a bedrock complex considered to be the Kenai Formation. The unit is seismically character- ized by numerous prominent reflectors, which dip steeply toward the west. In the western half of the area surveyed, this unit is overlain by a layer of unconsolidated material varYing in thickness up to a maximum of approximately 32-35 feet. The eastern half is characterized by outcropping reflectors, and could possibly be covered in areas with a thin veneer of unconsolidated material (Figure 3.3). No evidence of shallow faulting or gas-charged sediments was observed at this site. An east-west cross through the proposed site is shown on Figure 3.4. 3Ut 2 1 ]982 4.3 Area No. 2 Area No. 2 is underlain by a bedrock complex considered be the Kenai Formation. The unit is seismically character- ized by numerous prominent reflectors, which dip toward the west. Only.small isolated patches of unconsolidatd over- burden occur throughout the area, generally less than 5 4-3 feet in thickness, but lOcally ranging up to 10 feet thick. Only an occasional outcrOpping reflector was noted. No evidence of shallow faulting or gas-charged sediments was observed at this site. An east-west cross section through the proposed site is shown on Figure 3.5. RECEIVEO J U L 2 t 1982 Naska 0ii & Gas Cons. Commission Anchorage Mobil Oil Corporation P.O.
