It is situated on the easterly edge of a broad shelf adjacent to the deep channel of the Inlet which lies between the East and West Forelands. (See Figure 1-1.) The area is subjected to almost continuous tidal currents which peak at approximately 5 knots on the flood. The well was spudded on October 2, 1966 and suspended on June 4, 1967 after two seasons of drilling operations. It was drilled as a straight hole and reached TD at 14,367 ft. on May 29, 1967. The well was logged, but not tested. Downhole plugs were then set, a subsea wellhead corrosion cap installed and the rig demobilized. The well was drilled by Pan American Petroleum Corporation. The well was drilled as an ultra tight hole and, as was the practice at that time, minimal information was submitted to the Alaska Oil and Gas Conservation Commission (AOGCC). Late in 1994, the AOGCC contacted AMOCO Production Company (AMOCO) regarding verification that a top plug was set in the wellbore at the time of suspension. AMOCO retained Fairweather E&P Services, Inc. (Fairweather) to research the matter and develop a course of action. AMOCO no longer has active operations in Alaska, and consequently desires that a final abandonment of the well be entered into AOGCC records, and that a final location clearance be issued. In May of 1995, Fairweather submitted a report to the AOGCC entitled "Interim Report on Status of Pan American Petroleum Redoubt Shoal State 22064 No. 1 Well, and Proposed Program of Investigation." The report contains a compilation of all available well data from several sources, a brief review of regulations and industry practices in effect at the time the well was drilled, and some pressure profile information representative of the Redoubt Shoal area. In addition, the report proposed a program of further investigation which had the following objectives: Relocation of the wellhead; Determine if gas is leaking from or around the wellhead; and Determine the physical condition of the wellhead and assess the options for re- entering the well, if necessary. The AOGCC concurred with the investigative approach proposed by AMOCO in the Interim Report, and accordingly a field program was conducted in June of 1995 which addressed the above objectives. This report covers the results and conclusions stemming fi'om that investigation and requests an action by the AOGCC which will bring the Redoubt Shoal State 22064 No. 1 P&A issue to closure.

(See Figure 2-4.) 2.3 Operating Conditions and Methods The Redoubt Shoal State 22064 No. 1 Well is situated in an area of strong tidal currents, compounded by severe eddies and tidal tips. This is principally due to the constriction of Cook Inlet between the East and West Forelands. Slack water periods are shorter than those experienced in the main channel of the Inlet. This is particularly apparent on the flood, where the flood emerging from Redoubt Bay lags behind the flood moving up the main body of Cook Inlet. In these instances the main channel can be at high slack water and the flood is still flowing northeasterly out of Redoubt Bay. This condition translates into very short periods being available for good side scan and image sonar surveying in the area around the Redoubt Shoal State 22064 No. 1 location. In order to gain any reasonable daily survey production, side scan work had to be run on both sides of the slack until record quality deteriorated below what was useful. Many of the track lines passed through eddies and tidal rips which caused a brief smearing of the record due to yaw of the towfish. Despite these operational constraints, better than 125% side scan coverage was obtained in an area having a 500 ff radius around the reported well location. Bhthymetry was continuously recorded during all side scan runs. Positioning, side scan and bathymetry were interfaced through a PC based Sextant Hydrographic Surveying System. This suite of equipment was capable of one foot accuracy in horizontal position and 0.2 ft accuracy in depth measurements. Soundings were corrected for tide using predicted tides computed for Drift River Terminal and adjusted to the survey area. Bathymetric data was collected continuously during every positioning cycle thereby reducing accuracy problems associated with heave, pitch and roll of the survey vessel. This collection rate also enabled a more continuous seafloor profile to be stored to a magnetic medium for later analysis, post processing and map presentation. Side scan layback and drift corrections were made during post processing of the record. SUBSEA WELLHEAD INVESTIGATION 6 Figure 2-$ Imagenex Scanning Sonar Mounted on Seafloor Tripod sUBsEA WELLHEAD INVESTIGATION 7 Figure 2-4 Diving/Survey Vessel "Mdndy SUBSEA WELLI-[EAD INVESTIGATION If the subject wellhead could be clearly identified on the side scan record, it would have been further evaluated (particularly for escaping gas) by the color imaging sonar. In the event the wellhead was not clearly identified from the side scan records, the imaging sonar would be used to "sort out" the hard targets and define the wellhead, in preparation for a physical examination by a diver. 2.4 Chronology of the Investigation The diving/survey vessel "Mandy M", owned and operated by Marine Solutions Services, Inc., was mobilized for the project at Northstar Terminal in the Port of Anchorage. Mobilization required approximately one week, as the vessel had been laid up all winter and this was the first project of the season. In addition, the diversity of equipment required for the job necessitated a protracted period for installation, interfacing and checkout. The vessel departed the Port of Anchorage on Sunday June 4, 1995 at 1132 hours, a~er working its way offa mud bar adjacent to the dock. This could not have been avoided, as the berth assigned to the Vessel by Northstar Terminal is normally only used during the highest tidal excursions. Since this operation required the period of smallest tidal excursions, the encounter with the mud bar was a certainty. The vessel made a brief stop at OSK Dock in Nikiski enroute to the work area to take on fresh water, as none was available from Northstar Terminal. The vessel arrived in the work area at about 2305 hours, June 4, and immediately began side scan sonar work to attempt to locate the wellhead. Several passes were made before tidal currents forced a suspension of work at 0100 hours, June 5. Prior to anchoring up to wait out the tide, a weighted buoy was dropped on the reported well location to act as a visual reference. Side scan operations resumed at 0445 hours and continued until 0720 hours when the tide again made the sonar record unusable. The next period available for side scan work was between 1044 hours and 1316 hours. During this time the search area was expanded, as only one possible target had been observed and there was considerable doubt that it was the wellhead. Precision bathymetry was run concurrently with all side scan passes. A review of side scan coverage indicated that in excess of 100% coverage had been obtained around the reported wellhead location over an area having a radius of approximately 500 feet. Further study of the one questionable target reported above indicated that the scanning sonar should be deployed.. This was done on the next several slack tides. Image scanning sonar work continued during all available work periods until approximately 0900 hours June 6, 1995. During those periods the target was examined from several perspectives. Based on these images, and the fact that the target was the only one in the area that could not be clearly identified as a rock, a decision was made to jump a diver for verification. In preparation for the dive, the buoy was repositioned closer to the target to act as a down line. Survey gear was rigged down and dive gear prepared. The diver entered the water at 1825 hours June 6, using the buoy as a downline. He conducted a radial search of the bottom using a line tied to the clump weight buoy anchor. The diver determined that the target was a rock (See Section 3.4 herein.). Finding no other targets, the diver returned to the vessel. No further dives were justified, given the lack of target. SUBSEA WELLHEAD INVESTIGATION 9 Prior to departing from the survey area, three long bathymetric lines were run through the project area and extending southwest to the north end of Redoubt Shoal. This was done to define growth and migration of the shoal as it affected sedimentation in the well location area. The vessel then departed for OSK Dock in Nikiski, arriving there at approximately 0030 hours on June 7. The vessel was demobilized at that location later that day and all personnel but the vessel crew returned to Anchorage. SUBSEA WELLHEAD INVESTIGATION 10 3.0 RESULTS OF THE INVESTIGATION 3..! Bathymetry Interpretation of the bathymetric data collected in the area around the reported Redoubt Shoal State 22064 No. 1 location revealed bottom topography that is very similar to that shown on NOAA Chart 16662 (Cook Inlet, Kalgin Island to North Foreland). Bathymetry and Side Scan Sonar track lines are shown on the Trackline Map found in the pocket herein. Figure 3-1 is a bathymetric map of the surveyed area drawn on a one foot contour interval. The major inconsistency observed is in the water depth reported on the AOC~C well records. These records indicate that the water depth at the well location was -75 fi MLLW, and that the wellhead extended 7 f~ above the seafloor (-68 ft MLLW). The present survey shows the water depth at the location to be -64 fi MLLW, a positive difference of 11 ft. NOAA Chart 16662 shows the top ofthe wellhead at -57 ft (9-1/2 fathoms) MLLW, which would be roughly consistent with the present survey, were the wellhead present on seafloor as reported. Curiously, a check of NOAA Notices to Mariners shows no reference to the wellhead, yet it still apears on the chart as "Position Approximate." A rocky hard bottom persists over the survey area, characterized mainly by the cobbles. It is therefore hard to rationalize an approximate 10 ft accretion of the bottom over the past 29 years (wellhead installed in 1966). However some buildup of the bottom in the survey area is reasonable to expect due to the growth of Redoubt Shoal. The growth of the shoal and surrounding deposition is discussed in Section 4.2 herein, and was observed on three long bathymetric lines which connected the well location area with Redoubt Shoal. 3.2 Side Scan Sonar Fourteen (14) side scan sonar fines were run through'the area surrounding the reported well location (See Trackline Map in pocket). Numerous large rocks and boulders were observed on these lines, but only one target was identified as having the possible signature of a subsea wellhead. The individual sonar lines are found in the Appendix, and the suspicious target is shown from several perspectives in Figure 3.2. The sonar coverage overlapped sufficiently such that all parts of the seafloor in the area surrounding the reported location of the wellhead were observed from at least two (and usually three) perspectives. Tidal currents presented a major challenge to the side scan sonar effort. For reasons discussed in Section 2.2 herein, slack tides in the area are almost non-existent. The period of time chosen to complete the investigation should have provided the best slack water conditions available. However, tidal current influences from Redoubt Shoal, Kalgin Island, West Foreland and deep water channels combine to produce tidal rips and converging currents. This equates to difficult operating conditions fbr both side scan and image scanning sonar. The following is a summary of the 14 side scan sonar lines: Line 01: Line run South to North on 75 meter scale. Target identified between Shot Points 12 and 13 was revealed to be a boulder when observed from another direction (Line 08). Bottom is covered with very coarse materials, mainly cobbles and small boulders, and with numerous large boulders extending several feet above the seafloor.

This trackline passes directly over the reported wellhead location at Shot Point 147. The target identified between Shot Points 146 and 147 is the same suspicious target seen on several other tracklines, and later confirmed to be a boulder. The record is somewhat "smeared" locally due to tidal rips. The bottom is covered by coarse pebbles and cobbles with numerous isolated large boulders rising to varying heights above the seafloor. Line 14: Line run South to North on 50 meter scale. The reported wellhead location lies at the extreme outer edge of the port channel between Shot Points 159 and 160. The identified target at the inner edge of the same channel at the same location was later confirmed to be a large boulder. This same boulder appears on several tracklines (See Figure 3-2). Bottom is covered by coarse materials, mainly cobbles, with numerous isolated boulders extending up to 6 f~ above the seafloor. Side scan sonar is also an effective tool for identifying the presence of gas in the water column. The side scan records were analyzed in detail for gas, in the event the wellhead had corroded away or been buried in the sediment and was leaking gas. No trace of gas was found on any of the records, nor were any bubbles observed rising to the surface during the time that this investigation occupied the survey area. SUBSEA WELLHEAD INVESTIGATION 15 3.3 Imaee Scanning Sonar The target s~own in Figure 3-2 was of sufficient interest to deploy the color image scanning sonar. In order to provide a stable platform for these observations, the sonar head was mounted on a weighted seafloor tripod. The tripod has an orienting vane to keep it aligned in the current and prevent twisting of the armored cable that transmits data back to the survey vessel. The target was observed from several different deployments of the device, and from several perspectives. In every observation, the target gave very "hard" returns and had a general cylindrical shape that roughly suggested the shape of the wellhead being sought. (See Figure 3-3.) Every redeployment °fthe color image scanning sonar was very dependent on tidal conditions and associated currents. It was decided that further definition of the target by imaging sonar would be time intensive and probably yield no better data, given local operating conditions. Since the target is only about 100 f[ east of the reported wellhead location, and has the general image characteristics of the wellhead, it was further decided that a diver investigation was warranted. 3.4 Divine Diving in Cook Inlet is limited to periods of slack or nearly slack water, as a diver will have a very difficult time holding position on the bottom in current much greater than 1.5 knots. In addition, Cook Inlet is essentially a "black water" diving environment and diver observation and manipulation of objects is guided only by feel. For these reasons, dives need to be carefully planned and have specific objectives. The diving investigation of the only possible wellhead target in the survey area used a series of circumferential searches of expanding radii, with the buoy clump weight as an anchor for the search line. The diver located the target at approximately 50 ft from the downline and described the object as a rock with the appearance and dimensions shown in Figure 3-4. This information was described in real time by voice communication with the diver while on the bottom, and later confirmed by a sketch prepared by the diver when back onboard the vessel.

The lack of protection and maintenance is understandable since the well had been previously thought to be plugged and abandoned by both the operator and the AOGCC. However a recent review of records by the AOGCC revealed the possibility that the well was suspended rather than abandoned. The underlying purpose of this investigation was to assess the condition of the wellhead and determine a future course of action so the well can be accepted as plugged and abandoned by the AOGCC. The fundamental conclusion reached from this investigation is that the wellhead for Redoubt Shoal State 22064 No. 1 is not present above the seafloor at the reported location or in the surrounding area. The search area was wide enough to 'more than encompass any reasonable positioning differences between the 1966 reported position and the re-positioning techniques used in this investigation. Consequently position error cannot be considered as a reason for not finding the wellhead. This leaves corrosion and deposition as two other possibilities, both of which probably play a role in the loss of the wellhead. 4.1 Corrosion Effects Corrosion rates for unprotected steel structures in Cook Inlet are known to be very high. This is due to the following factors: High current velocity combined with high suspended sediment loads produce a hydroblasting effect which continuously cleans metal surfaces of any corrosion products as fast as they accumulate. Therefore a continuous fresh metal surface is presented to the marine environment. The waters of Cook Inlet are rich in oxygen, most of which is contributed by fresh water streams flowing into the Inlet. The strong tidal currents of the Inlet mix this oxygen throughout the water column, and consequently corrosion occurs at all depths in the Inlet. In addition, these tidal currents prevent an oxygen depleted boundary layer from forming adjacent to metal surfaces, as would be expected in calm waters. Therefore oxygen rich waters are constantly in contact with fresh metal surfaces. Corrosion protection in Cook Inlet usually requires approximately 35 milliamps per square foot of matal surface. In other less severe environments, 15 to 20 milliamps seems to be the norm. Since the subject wellhead has been unprotected and unobserved for 29 years, the accumulated effects of corrosion were considered in explaining its loss. To better understand these effects, several acknowledged corrosion experts with Cook Inlet experience were contacted and asked about unprotected metal corrosion rates: Paul Guy, Corrpro. verbal communication 6-26-95: Says a 20 lb. metal loss from a square foot of fresh metal surface in Cook Inlet could be expected. This equates to approximately 0.5" of metal from a square foot of exposed metal, which seems on the high side. SUBSEA WELLHEAD INVESTIGATION 19 Joe Delbraith, CTI, verbal communication 6-26-95: Says 100 mils (0.100") per year is reasonable to expect on unprotected metal surfaces in Cook Inlet. Bob Visser, Belmar Engineering, verbal communication, 6-26-95: Says up to 35 mils (0.035") per year accompanied by much deeper pitting has been observed. Also says 1/2" of metal loss in 20 years is very reasonable to expect on unprotected structures. Eric Hedborg, Hedborg Associates, Inc., verbal communication, 6-26-95: Says up to 60 mils (0.060") per year were observed on the wear plates of Cook Inlet platforms before cathodic protection was installed, and in two cases, between 80 and 100 mils (0.080" to 0.100")'per year were measured. In another instance, an unprotected pipeline spool had corrosion of 120 mils (0.120") in two years on the bottom. While all of these sources are not in total agreement, the corrosion rates reported for unprotected surfaces are high enough to have destroyed the subject wellhead over the 29 years it has been exposed to Cook Inlet waters. Since the wellhead was reported to stand 7 t2 above the seafloor, it would be reasonable to expect the corrosion would be able to attack the thinner metal of the well casing where it mated to the wellhead housing. Given the above corrosion rates, the casing may have failed and allowed the wellhead to fall over. Corrosion would then continue to attack what was left. Admittedly, subsea wellheads contain a lot of metal, and some parts of the housing may have been an inch or more in thickness. Some of this material may still remain, but lie buried in the sediment. 4.2 Deposition The depositional environment in Cook Inlet is reflective of strong tidal currents and high rates of sediment transport. Streams and rivers that enter Cook Inlet seasonally carry high sediment loads, yet no deltas form at the mouths of these streams. The contributed sediment is essentially carried away as fast as it is introduced into the Inlet. A prime example can be seen in Redoubt Bay where the eruption of Mt. Redoubt in 1992 partly melted a glacier and produced flood discharges in Cannery Creek that reportedly exceeded 100,000 cubic feet per second. These torrential discharges carried thousands of tons of sediment into the Inlet ranging from sand and silt to boulders several feet in diameter. Today there is no delta at the mouth of Cannery Creek. This material has for the most part, been redistributed by tidal currents and has resulted in the growth of Redoubt Shoal as well as the deposition of some material in the areas to the North. Years of side scan data accumulated from the monitoring of subsea pipelines in Cook Inlet have demonstrated that tidal currents, particularly those associated with maximum tidal excursions, can move coarse sediment bed loads such as large pebbles and cobbles. It is suggested that this process has resulted in some recent sedimentation in the Redoubt Shoal State 22064 No. 1 area. Subsequent to this influx of material, a progressive winnowing of the fines has occurred which has resulted in the SUBSEA WELLHEAD INVESTIGATION 20 armored cobble bottom observed today. It is unrealistic to imagine this deposition to be thick enough to bury the entire wellhead. However, it clearly has been sufficient to mask the bottom, as none of the debris that is most always observed around old subsea exploration drilling sites (i.e., bits, pieces of pipe, drums, drilling line, scrap iron, etc.) was observed in the survey area. 4.3 Summary of Present Day Site Conditions The following conclusions can be drawn from this investigation and from other sources of data concerning the dynamics of the Cook Inlet marine environment: The Redoubt Shoal State 22064 No. 1 wellhead no longer exists at its reported location, or within 500 feet of its reported location. The loss of the wellhead can most likely be attributed principally to corrosion, and with any remaining debris being covered by recent sedimentation. There is no gas in the water column or emanating from the seafloor within an area covering 500 feet around the reported wellhead location. Under present site conditions relocation of the wellbore beneath the seafloor by magnetic means would be highly problematical at best. If located, excavation and re- entry would be nearly impossible to achieve. The wellbore represents no hazard to the environment in its present condition. The well was originally a dry hole with no hydrocarbons encountered. If the wellbore itself were exposed due to loss of the wellhead, it would act as settling weir and soon fill with rocks and other sediment. SUBSEA WELLHEAD INVESTIGATION 21 5.0 REQUESTED AOGCC ACTIONS Given the present day site conditions described in Section 4.3 above, it is requested that the AOGCC accept the current condition of the Redoubt Shoal State 22064 No. 1 well as effectively plugged and abandoned. AMOCO and Fairweather E&P personnel are available to discuss this report with AOGCC personnel if there are questions concerning the conclusions drawn or the request for P&A approval.

(See Figure 1-1.) The well was spudded on October 2, 1966 and suspended on June 4, 1967 after two seasons of drilling operations. It was drilled as a straight hole and reached TD at 14,367 t~. onMay 29, 1967. The well was logged, but not tested. Downhole plugs were then set, a subsea wellhead corrosion cap installed and the rig demobilized. The well was drilled as an ultra tight hole and, as was the practiCe at that time, minimal information was submitted to the Alaska Oil and Gas Conservation Commission (AOGCC). Recently, the AOGCC has contacted AMOCO Production Company regarding verification that a top plug was set in the wellbore at the time of suspension. AMOCO contracted Fairweather E&P Services, Inc. (Fairweather) to research the matter and develop a course of action. AMOCO no longer has active operations in Alaska, and consequently desires that a final abandonment of the well be entered into AOGCC records, and that a final location clearance be issued. The wellhead on the seafloor has remained unobserved and undisturbed for essentially 28 years. In order to bring the abandonment of this well to closure, AMOCO and Fairweather have conducted an exhaustive search, both in-house and through outside sources, for original well data. The results of this search are described in Section 2.0 herein. Based on AMOCO's understanding of the current status of this well, a program of investigation is being proposed to determine actual site and wellhead conditions, including checking for gas escaping from or around the wellhead. The issue is fairly straight forward: Does the current condition of the well satisfy AOGCC requirements in effect in 1966-67 for plugged and abandoned wells. 2.0 CURRENT WELL STATUS 2,1 AOGCC FILES The Redoubt Shoal State 22064 No. 1 well is carded on the AOGCC Master Well List as plugged and abandoned effective June 4, 1967, however the well files do not contain any P&A documentation (old Form P-15). The chronological well history indicates that a bridge plug was set at 1995 ft. RKB, followed by the installation ora wellhead cap. This procedure, along with the downhole cement plugs, would have been sufficient to place the well in suspended status only, since a surface plug has always been required for an approved P&A under AOGCC regulations. The AOGCC files contain only the minimal information required by the Commission in the 1966-67 time frame. The well was drilled as a tight hole, and the submittal of minimal data on tight holes was the industry practice at the time. Pertinent information from the AOGCC files in this well is included Redoubt Shoal State 22064 No. 1 in Appendix I. We have reviewed the well files and the wireline logs and have determined that no commercial hydrocarbon zones were encountered in the well. Unfortunately, we cannot determine with certainty if a top cement plug was set in the well. The well history (see Appendix I) does not mention a top or surface cement plug; however, other Pan American wells drilled in Cook Inlet during the same time frame had near surface plugs set as standard procedure. The following is a summary of downhole conditions taken from AOGCC well records: Water Depth: Original RKB Elev.: Wellhead Elev.: TD: Casing: 75 f~ MLLW +31 fi MLLW (Depth reference) 7 ft above mudline 14,367 fi MD & TD 20" ~ 632 ft (Cemented to mudline) 13-3/8" ~ 2014 ft (Cemented to mudline) 9-5/8" ~ 11,839 ft (Top ofcement ~ = 10,000 ft) Rig: Offshore Company -"Polar Cub" (jackup) Plugs: 12,750 ft - 12, 850 fi (net 100 ft) open hole cement plug 11,790 ff- 11-890 ft (net 100 fi) cement plug across shoe of 9-5/8" casing 11,700 ff - Bridge Plug 1,995 ff- Bridge Plug Mudline: Steel Corrosion Cap on subsea wellhead Figure 2-1 shows the current condition of the well, insofar as can be determined from available data. 2.2 SEARCH FOR ADDITIONAL DATA Information regarding wellhead specifics, mud weights, drilling parameters, mud log data (i.e. ditch, cuttings, and background gas) and tests of plugs are not included in the AOGCC files. In an effort to fill in some of the data gaps, an intensive search for additional information was made using the following sources: AMOCO Production Company (Houston and Denver offices) Mud companies (M-I Drilling Fluids, Baroid, and Baker Hughes INTEQ(Milpark)). Drilling Contractor (Sonat Offshore Drilling Inc., successor to The Offshore Company) Subsea Wellhead Companies (Cooper, FMC, ABB Vetco Gray) Wireline Logging Company - Schlumberger AOGCC - Both internal and public files Unfortunately, the passage of twenty-eight years has resulted in the loss of much of the information that was sought. The situation has probably been compounded by the fact that the well was an ultra tight hole originally and service companies files were pretty much "sanitized" in the name of data security. The following paragraphs summarize the data search: Redoubt Shoal State 22064 No. 1 AMOCO PRODUCTION COMPANY CURRENT CONDITION - REDOUBT SHOAL 22064, #1 03/07/95 Wellhead Cap 20" @ 652' BP @ ~ 1,995' 15 $/8" ~ 2014' TOC Esflmated @ ~ 10,000' BP @ ~ 11,700' Cml Plug 11,790' - 11,890' (Net 100') 5/8"@ 11,859 2 1/4" hole) O.H.

All well records were transferred to Houston at that time, however some were apparently lost in transit or misdirected and have never been subsequently found. The Redoubt Shoal State 22064 No. 1 file is among those missing. The recent search at AMOCO failed to find any data on the well. Mud Companies: In an effort to gain some confirmation of the mud weight in the well at the time it was suspended, all local mud companies were contacted and their archives searched. The drilling fluid industry has gone through numerous mergers and reorganizations over the years and it may be that the drilling fluid was supplied by a company no longer in business. A review of other wells drilled in the Redoubt Shoal area led us to believe the most likely mud companies were either Magcobar or Imco. When these two companies merged several years ago, (M-I Drilling Fluids) all records in Alaska were consolidated. A thorough search of the M-I archives failed to turn up any record of the subject well. The search did yield some valuable information on three nearby wells (Redoubt Shoal State No. 2, North Redoubt No. 1, and Redoubt Bay No. 1). Mud weight ranges used in these wells were: OPERATOR Pan American Pan American Union Oil of California WELL NAME Redoubt Shoal State No. 2 North Redoubt No. 1 Redoubt Bay No. 1 MUD WEIGHT RANGE 9.0- 9.8 ppg 9.1 - 10.8 ppg 8.7- 10.3 ppg These mud weights are considered representative of the Redoubt Shoal area. A search of the Baroid and Baker Hughes INTEQ (Milpark) archives yielded no information on the Redoubt Shoal State 22064 No. 1 well. Drilling Contractor: The Redoubt Shoal State 22064 No. 1 well was drilled from the Offshore Company jackup rig "Polar Cub". Sonat Offshore Drilling Inc., the successor to The Offshore Company, was contacted regarding the rig and any records they may have on the drilling operations (i.e. IADC daily drilling reports). We were informed that Sonat only keeps operations records back to 1980, and therefore had nothing on the subject well. The "Polar Cub" was a four-legged jackup, and was last used in Lake Maricaibo, Venezuela. Sonat was sure the rig has been scrapped. Since the well had been re-entered following an over-winter operations shutdown, it was clear that the subsea wellhead must be some early version of a mudline type suspension system or a subsea predecessor of the mudline system. Wellhead Companies: Discussions with FMC, Cooper Oil Tools, and ABB Vetco Gray personnel led us to the conclusion that a Cameron subsea wellhead was used on the well. Nearly all offshore wells drilled in Cook Inlet during the middle 1960's used the Cameron System. The current Cooper Oil Tool (successor to Cameron Iron Works) representatives in Alaska had no records on the well and were unfamiliar with the Redoubt Shoal State 22064 No. 1 subsea wellhead systems in use during the 1960's. We were finally able to locate Mr. Don R. Deitz who was the Cameron Iron Works representative in Alaska when the Redoubt Shoal State 22064 No. 1 well was drilled. Mr. Deitz ran the wellhead on the subject well and identified it as a Cameron Streamline Subsea Wellhead System. Mr. Deitz generously provided some old photographs of the wellhead components, as well as his recollection of the procedures used in running the system. This information is included in Section 2.3 herein. Wireline Logging Company: Schlumberger Well Services was contacted as a possible source of well data beyond what is shown on the log headers. With the exception of the 17-1/2 inch surface hole, all references to mud weights, viscosity, pH and fluid loss has been deleted from the log headers. The mud weight at the 13-3/8"casing point (2014 ft MD) was 9.7 ppg. A search of Schlumberger's archives proved fruitless in turning up additional information. AOGCC: In an effort to be sure we had seen everything the AOGCC had on the well, we visited with Commission personnel and went through the files a second time. Nothing new was discovered. 2.3 WHAT WE KNOW AND WHAT WE DO NOT KNOW The most significant information gaps are in the areas of mud weights and the condition of the wellhead. There is nothing in the well records or on the logs that suggests any well control problems or abnormally pressured formations. If it can be assumed that the mud program used in the drilling of the Redoubt Shoal State 22064 No. 1 well was similar to that used in other Redoubt Shoal area wells, mud weights were probably in the 9.0 - 10.5 ppg range. Figure 2-2 shows representative pressure profiles for the Redoubt Shoal area and suggests probable mud weights used in the program. The point to be made is that the hydrostatic pressure of the mud left in the hole at the time the well was suspended in 1967 is adequate to control formation pressures. In addition, even though the 9-5/8" X 13-3/8" annulus apparently is not sealed by a cement plug, the desiccation of the mud in this annulus over the last twenty-eight years has probably formed a plug of adequate strength. An annulus plug was not required at the time the well was drilled. The Cameron Streamline Subsea Wellhead System used a design that incorporated some features of both a modern mudline suspension system and a subsea wellhead system. Apparently no temporary or permanent guide structure was used, and all blowout prevention equipment was on the surface. The components and running sequence are summarized as follows: · A 30" or 36" conductor was driven to refusal from the drilling vessel. · A 26" surface hole was drilled to the 20" casing point.

Returns were taken to the seafloor. The wellhead was run concurrent with the 20" casing string using drillpipe and a welhead running tool. The 20" casing was cemented through drillpipe. The wellhead landed on the 30" stub with steel gusset plates on the wellhead section. (Figure 2-3 gives a schematic interpretation of the 20" low-pressure wellhead housing.) A 17-1/2" surface hole was drilled to the 13-3/8" casing point. 13-3/8" casing and the high-pressure 13-5/8" subsea wellhead component were run using a wellhead running tool on drillpipe or on casing. The casing was cemented and the 13-5/8" wellhead section landed and sealed on an internal profile in the 20" wellhead section. After running and cementing the 13-3/8" casing string, the 13-5/8" wellhead section extended above the 20" section. A high pressure 13-5/8" riser was attached to the wellhead using a diver installed clamp. All subsequent drilling operations were conducted through this riser. 9-5/8" casing was hung inside the 13-5/8" housing using the forerunner of the modern stack- down mudline hanger system. (Figure 2-4 gives a schematic interpretation of the Cameron Streamline Subsea Wellhead System in the drilling configuration for deeper sections of the hole.) When the well was suspended, the 13-5/8" high-perssure riser was detached and a corrosion cap was clamped into the 13-5/8" hub on the wellhead. The corrosion cap was equipped with a 2/16" 5000 psi gate valve on top. Assuming the above procedure was followed, Figure 2-5 shows a schematic interpretation of the anticipated wellhead geometry at the 22064 No. 1 location. Figures 2-6 and 2-7 show Cameron Streamline Subsea Wellhead System components. According to Mr. Deitz, Pan American Petroleum Corporation ordered eleven of these systems for exploratory drilling operations in Cook Inlet.

Cameron Streamline Subsea Wellhead System Circa 1966 Figure 2-7 13 The present condition of the wellhead is unknown, as it has not been inspected any time during the last twenty-eight (28) years. The area in which the wellhead is located experiences very strong tidal currents, high corrosion rates and high suspended and bottom sediment transport rates. To our knowledge, other abandoned subsea wellheads in Cook Inlet have no post-abandonment inspection history either, so no assumptions on wellhead condition can be made based on parallel experience. An evaluation of the condition of the wellhead is essential before deciding on any future course of action. 2.4 REVIEW OF CIRCA 1967 STANDARD INDUSTRY PRACTICES AND AOGCC REGULATIONS The AOGCC regulations in place at the time the Redoubt Shoal State 22064 No. 1 well was drilled (1966-1967) contained the specifics on well plugging and abandonment that are listed below: Rule 201. PROCEDURE FOR PLUGGING. Each abandoned hole or well shall be plugged by or on behalf of the owner, operator or producer who is in charge of the well and responsible therefor. Unless a different method and procedure shall be approved by the Commission upon application by the owner, operator or producer on Form No. P- 15, the method and procedure for plugging the well shall be as follows: 201.1 The bottom of the hole shall be filled to, or a bridge shall be placed at, the top of each producing formation open to the well bore, and in either event a cement plug not less than fifty (50) feet in length shall be placed, whenever possible, immediately above each producing formation open to the well bore. 201.2 A cement plug not less than fifty (50) feet in length shall be placed at approximately fifty (50) feet below all fresh-water-bearing strata. 201.3 A plug shall be placed at or near the surface of the ground in each hole. 201.4 The interval between plugs shall be filled with heavy-mud-laden fluid. 201.5 An uncased hole shall be plugged with heavy mud up to the base of the surface string, at which point a plug of not less than fifty (50) feet of cement shall be placed. Within thirty (30) days after plugging of any well, the owner, operator or producer responsible therefor who plugged or caused to be plugged the well shall file with the Commission, an affidavit of Form No. P-15, setting forth in detail the method used in plugging the well. Rule 202. MARKER, WELL. The exact location of the abandoned hole shall be shown by a steel marker at least four (4) inches in diameter and at least ten (10) feet long set in concrete and extending at least four (4) feet above ground level. (Not a factor in offshore operations) With the possible exception of the interpretation of the surface plug, it appears that these regulations have been satisfied in the suspension/abandonment of the subject well, however the well files do not contain copies of P&A Form No. P-15. Redoubt Shoal State 22064 No. 1 14 At the time the Redoubt Shoal State 22064 No. 1 well was drilled, it was common practice to set downhole plugs sufficient for abandonment, but declare the well "suspended" in order to hold a lease. Subsequently, these wells were declared "plugged and abandoned" without any additional work, once the need for the suspended well had passed. This was acceptable as long as the necessary plugs had been set at the time the well was suspended. During that era, the AOGCC was fairly generous on what constituted an acceptable "surface" plug. Many offshore wells drilled in this time period had surface plugs set with tops three or four hundred feet below the mudline to facilitate possible future re-entry. This may have been the intention in the case of the subject well. 3.0 PROPOSED PROGRAM OF INVESTIGATION Prior to considering any regulatory relief regarding a surface plug, AMOCO will conduct a field investigation that has the following objectives: · · Relocation of the wellhead. Determine if gas is leaking from or around wellhead. Determine physical condition of the wellhead and assess the options for re-entering the well, if necessary. Relocation of Wellhead: The wellhead will be relocated by radio-positioning techniques which duplicate the original location survey insofar as possible. The site will be surveyed by side scan sonar to verify the existence of the wellhead and assess general site conditions. Bathymetry will be run concurrently with the side scan survey. Determination on gas leaking from wellhead: Once the wellhead has been relocated, a diving/survey vessel will be securely moored approximately 100 feet away from the' wellhead. An image scanning sonar will be lowered into the water column at slack tide and the wellhead will be scanned for leaking gas. Due to the absence ofsubsea visibility resulting from suspended sediment in the water, the sonar survey is required to observe the wellhead. Obviously, a serious leak would have been seen on the surface previously, since the area is heavily fished in summer months, but a small leak would probably go undetected and would surface intermittently some distance from the wellhead due to the current. The image scanning sonar survey is the only technique which can clearly detect gas in the water column. This survey is necessary to prepare for the diving work to follow. Determination of Physical Condition of Wellhead: The diving/survey vessel will be repositioned over the wellhead and divers deployed for a physical inspection. Diving will necessarily be limited to slack tide periods. The wellhead may have to be water blasted clean of any accumulated marine growth before definitive information can be gained. Depending on what has been observed on sonar records, black water photography may be required to adequately assess the condition of the wellhead. The diving/survey vessel will be equipped for this eventuality. The diving work will confirm the 'size and condition of wellhead components, verify the type of corrosion cap used and the presence or absence of any check or manual valve on the cap. Redoubt Shoal State 22064 No. 1 15 The diving work will also provide information that will be used to assess chances of successfully re- entering the well if that proves necessary. AMOCO feels the above work, while expensive, can be accomplished with a high expectation of achieving all objectives. The results of this work will be provided to the AOGCC for evaluation. Any further work will be dependent on survey results and the outcome of meetings with the AOGCC. There is no assurance at this time that the wellhead can be re-entered. The wellhead has been unobserved for twenty eight years and attempting to re-enter the well may compromise what integrity presently exists. For this reason, AMOCO is reluctant to pre-commit to a course of action that may ultimately prove impossible or unwise to carry out. The survey and diving work will have to be completed by June 16, 1995 in order to avoid conflicting with the commercial drift net salmon fishery which heavily uses the well site area. Tidal excursions in the area of the well are in the 15 to 20 ft. range. AMOCO proposes to conduct the inspection work between June 4 and June 8, 1995 to take advantage of minimal tidal ranges, and maximum periods of slack water. This will optimize the efficiency of underwater operations insofar as possible. If any additional work is required, it is recommended that it be deferred until after the close of the commercial fishing season. / 4.0 REQUESTED AOGCC ACTIONS AMOCO requests that the AOGCC schedule an informal meeting to discuss options regarding the abandonment of the Redoubt Shoal State 22064 No. 1 well, and the proposed program of investigation described herein. Due to seasonal operational constraints resulting from the commercial fishery in the area, we suggest this meeting be held in early May 1995 in order to allow time to get the work done. AMOCO will prepare a report covering the results of the diving and survey work. Following the submittal of this report, we request that AOGCC schedule another meeting to review the report and discuss reasonable abandonment options, based on survey results.

ATION SECURITY LIFE BUILDING DENVER~ COLORADO 80202 January 5, 1967 Mr. Thomas R. Marshall, Jr. Department of Natural Resources Alaska Oil and Gas Conservation P. O. Box 1391 Juneau, Alaska 9 ANCHORAGE Dear Mr. Marshall: This will confirm our verbal discussion held in your office December 3, 1966~ relative to ~he Pan American Redoubt Shoal No. 22064 wildcat well located in Section 26, Township ? North, Range 14 West, SM, Kenai Burrough, Alaska. During our conversation, we pointed out drilling of the above well was temporarily discontinued because of ice conditions in the Inlet, and that the hole would be re-entered in the Spring of 1967, as soon as ice and weather conditions permitted. Because of the conditions stated above, we questioned whether the well should be classified as suspended, in the normal interpretation of the State regulations, or if the State regarded drilling operations on the well discontinued temporarily due to ice conditions in the Inlet. In answer tomy question, you furnished a copy of a letter dated December 1, 1966, directed to Tenneco Oil Company in response to their inquiry relative to the Starers position of the handling of well logs and other confidential information of wells drilled in the ia~-ediate vicinity of unleased Federal or State acreage. Your letter offered a proposal for consideration that would protect confidential information filed with the State by the operator on wells drilled offsetting open State or Federal acreage, and at the same time apply with existing State laws and regulations. In view of your pending plans to formalize a State polic~, and seek approval with a policy by the Comaissioner of Natural Resources, you ad- vised that PanAmerican should withhold the filing of confidential data and well logs on the Redoubt Shoal No. 22064 well until such a policy had been approved by the State. We would appreciate your current thoughts and industry'reaction, if any, to the proposal contained in your letter of December 1~ 1966~ to Tenneco Oil Company. In the meantime, we will comply with your suggestion not to file confidential information or well logs on the Kedoubt Shoal well un=il the matter has been clarified. Very truly yours, ~----..- R. W.

E. j. Huizer Water Rights Coordinator Division of Commercial Fisheries ADF~G, Juneau State of Alaska DATE : September 16, 1966 SUBJECT: This memorandum is in reference to the request by Pan American Petroleum Corporation to drill a test well from a floating barge in Cook Inlet approximately 1 mile east of 60° 40' N. Latitude and 1S1° 40' West Longitude. The leased designation is "Redoubt Shoal State, ADL 22064." It is the understanding of the Department of Fish and Game that Pan American Petroleum Corporation wishes to commence work on the test well as soon as possible. The location selected for this well lies in an area heavily utilized by the drift gill net fleet during open salmon seasons in the summer. Early completion of the test Well so that equipment can be removed prior to the opening of the 1967 salmon season will be desirable. It is understood, of course, that favorable results from this initial wildcat well may result in additional test drilling for the establishment of a permanent drilling platform in the area. Should this eventually arise, special precautions relating to the drift .gi!l~.~et fleet will have to be instituted in line with those discusse-~ ~.~i~~p-~'~n~tatives of Pan American Petroleum Corporation, Department of Natural Resources, and Department of Fish and Game earlier this year in Roscoe Bell's office. The drilling of a test well at the proposed location will not adversely affect the fish and game resources of the area if special precautions are taken to prevent any occurence of oil polution. Therefore, the Department of Fish and Game has no objection to the application. cc: C. H.
