From:Davies, Stephen F (OGC) To:Cassi Campbell Cc:Kair, Michael N (OGC); Guhl, Meredith D (OGC); Junke, Kayla M (OGC) Subject:RE: Discovery of Prudhoe Bay Date:Friday, March 3, 2023 10:55:52 AM Cassi, Q: I'm trying to confirm the date of oil discovery at Prudhoe Bay. I'm finding conflicting information saying both 3/12/68 and 3/13/68. Are you able to confirm? Short Answer: March 12, 1968. Details: Page 304 of the well history file (Permit 167-011) for the Prudhoe Bay State #1 exploratory well, which is the discovery well, shows that Drill Stem Test #5 (DST #5) , conducted from 9,505’ to 9,825’ measured depth on 3-12-68, produced at a rate of 1,152 barrels of oil per day (BOPD). NOTE: 0% means no water was produced during the test. 1320 MCF/D means associated natural gas flowed at a rate of 1,320 thousand cubic feet per day (which equals 1,320,000 cubic feet per day), 26.9 degrees is in units of degrees API, which is a measure of the oil viscosity, 1140 GOR is the gas-to-oil-ratio, for the test, TP 200 psi means the tubing pressure was 200 psi, and the well was flowed through a ¾-inch choke valve during the test. I did not see any separate description for operations conducted on 3-13-68 within this well file. DST #4 previously conducted on 3-10-68 failed. Earlier DST #3 flowed oil to the surface, but at a rate estimated less than 100 barrels per day. Previous DST #2 yielded only gas, and initial DST #1 flowed a small amount of gas and recovered some oil from the drill pipe but no flow rate was provided. So, based on my quick review of the 349-page scanned well history file, I would say that 3-12-68 was the first date that flow tests recovered oil in significant quantities from the Prudhoe Bay State #1 discovery well. You can review the page in the well history file for Prudhoe Bay State #1 shown above by opening AOGCC’s DataMiner application on our website, clicking on the key word “Wells” or the blue-colored “Wells” box on the AOGCC Data Miner page, typing the Permit Number for the well 167011 into the box beneath the column label “Permit”, clicking on the blue-colored number 167011 in the Permit column, which is a hyperlink that opens the scanned well history file, clicking the “Sign In” button (the user name and password are filled in automatically), waiting 2 or 3 seconds and then clicking the “OK’ button on the “Change your password” message (these steps are needed because we have had problems on our website being clogged by web-crawler bots that constantly take up all of our licenses for this software), typing the page number 304 into the box to the right of the down-arrow near the top of the page, and clicking the “Go” button.

Contingent Approval 399-094 (6/16/99) - ~eview Approval number 399-094 to our Application for Sundry Approvals was contingent upon a satisfactory structural review for. imposed wind loading. A structural review was undertaken as part of the design of the monument and the mounting to the well casing by a registered structural engineer. Attached is a copy of the structural design criteria including the design assumptions specifying a safety factor of 1.5. The design was checked for wind loading of 100 mph and met the criteria. His analysis concludes that the existing well casing configuration should provide ample support for the monument. However, if any problems are detected, guy wires are an option.

Michael Bill AR3B-6003-93 242-2603 ARCO DISCOVERY WELL PRUDHOE BAY STATE #1 ARCO MONUMENT STRUCTURAL DESIGN CRITERIA GENERAL DESCRIPTION: The new monument sculpture will resemble the ARCO Spark and will be made up of 16" Dia. x .500 wt. Pipe. The monument will stand approximately 35 feet high above pad grade. The spark sign itself will have an overall dimension of 26'x26'. The monument will be welded to a wide flange beam at the bottom. The monument beam will then bolted to a 2" pile cap plate and supported by pipe stubs welded to the 13.37Y' and 20" Dia. well casing ring. The pile cap system will basically consist of a 2"cap plate welded to a 16"Dia. pipe stub and a 18" Dia. pipe stub welded to the 16" pipe stub. It was noted that the top of the 13"Dia. well casing had been cut 5" below pad grade. WELL CASING CONFIGURATION: Information received from Mike Bill indicate that within the 13.375" Dia. well casing there is also an 8" casing string. In addition, there is also a 20" and 30" Dia. casings strings surrounding the 13.375" dia. casing. All casings in between appear to be filled with cement/slurry. A sketch of the well configuration is enclosed as Attachment 1. DESIGN ASSUMPTIONS: Wind Load = 1 OOmph (applied to the broad side of the monument) Fy (steel) = 36 ksi (plates), 50 ksi (shapes) Bolts = ASTM A-320 or better Safety Factor = 1.5 DESIGN REFERENCE FOR WIND LOADS: ASCE STANDARDS ASCE 7-88 Uniform Building Code 1994 ARCO Spec CRT-SS-NS-30001 ANALYSIS The structure was checked primarily for wind induced loads using 100 mph wind. The wind load was applied on the broad side of the monument for maximum load results. A 1.5 factor of safety was used in the design analysis as required per ARCO Spec. It was assumed the critical point of failure to the structure would be at the cap plate connection for shear and overturning. A conservative approach was used in determining wind load coefficients in the calculations. The existing well casing configuration string and foundation should provide ample support for the monument. Heat transfer was not considered a major problem since the only heat source to the structure would be radiant heat from the sun. The multiple casings and surrounding concrete will help suppress any heat transfer to the permafrost areas. Other Historically, We are not aware of any foundation failures to slurried support piles due to radiant heat transfer on the slope. Deflection to the structure was analyzed and considered minimal (1" range). This would indicate the structure is fairly stiff and that we should not anticipate any problems or failures due to vibration. RECOMMENDATIONS: Guyed wires attached to the structure and anchored to pad could be employed for additional stability.

The well was Plugged and Abandoned on April 14, 1985. ARCO plans to change the location and form of the abandonment marker placed on the well. In 1985, a steel plate was welded to the casing stub with pertinent well information bead welded on the plate. A new monument marker will be placed at the site later this summer and secured to the casing stub. A steel plate containing the well information required under 20 AAC 25.120 will then be welded to the monument. Attached is a photo of the planned monument taken in the fabrication shop. Commemorative plaques may also be located at the well site and/or on the Central Gas Facility pad. This plan was discussed and verbally approved in concept on May 11, 1999 by Commissioner David Johnston in a conversation with Willy Friar and Jim Short of this office.

Inc. P. O. Box 100360 ,Anchorage. AK 99510-0360 Dear Messrs. Johnson and Gurule' Re:.' ARCO Alaska, Inc. Inactive Drilling Waste Disposal Facility Closure - Prudhoe Bay State #1 6'~"~1 The Alaska Department of Environmental Conservation (ADEC) has received and completed its review of your submitted documents requesting approval for closure of BLM/USGS Drilling Waste Disposal Facilities on the North Slope in the National Petroleum Preserve Alaska. These sites have been reviewed in accordance with the ADEC Interim Site Assessment Guidance for Inactive Drilling Waste Sites, June 1991. A site visit was made in August 1994 to those sites that received public comments during the closure public notice period: Cape Halkert. East Teshekpuk No. 1, Ikpikpuk No. 1, East Simpson No. 1, and East Simpson No. 2. The correspondence describes our review procedures. 'puts forward the department's findings, and takes action upon the request to close numerous sites. Currently, the second draft of Alaska's new Solid Waste Regulations,' 18.AAC 60, are under review, and this second draft contains a chapter on Inactive Reserve Pit closures. The closure criteria in this proposed regulation parallels the closure criteria in the 1991 Guidance Document. Closure under the 1991 Guidance Document should constitute closure under the proposed Solid Waste Regulations if they are adopted as current drafted. The qualitative risk screening procedure required in the above referenced document determines whether a site presents negligible levels of risk, or if it is a significant risk generator. A decision scheme is then employed to establish (1) whether or not there is a basis of concern, and (2) whether or not a waste site is likely to present significant'risk to human or environmental receptors. Messrs. Johnson and Gurule January 19. 1995 .~RCO Inactive Drilling Waste Disposal Facility. Closure Approval The first step in this screening criteria is establishing a basis of concern: "If the waste site has released contaminants or there are mechanism for potential releases and there are receptors nearby, then. there may be cause for concern, and the waste site should be studied further." and "If there is no release of contamination or no mechanisms for potential releases and there are no receptors nearby, then there is not a basis for concern and t_he waste site should be considered closed." The criteria that are measured at a waste site to satisfy the above logical arguments are: Evidence of release of chemical contamination at the waste site in excess of Alaska Water Quality Standards for one or more target compounds, or Mechanism for potential release, and Proximity. of the waste sire to biological receptors. If'either of the first two criteria and the last criteria are met. there is a basis for concern, and before proceeding with Step 2. a corrective action plan shall be prepared for the sire which shall identify, alternative ways to correct or mitigate the basis of concern, prevent its recurrence, and select a preferred approach. Corrective action alternatives shall be described at a conceptual level, and the selection of a preferred approach shall be based on balancing protectiveness with implementability and cost-effectiveness. The second step determines whether contamination at a waste site present a risk to receptors that is significant. If risk is found not to be significant, it is considered to be "negligible." The finding or significant risk is based on the likelihood of exposure and the likel[:no~od of adverse consequences of exposure: "For risk to be considered significant, the receptors must be vulnerable to exposure, and the consequences of exposure must be 'adverse' to human or animal health or the environment," and. conversely, "If exposure is unlikely or the consequences of exposure are not 'adverse,' then the risk is negligible. If risk at a waste site is signficiant, then corrective action should be taken. The criteria ii, at are measured at a waste site to satisfy, the logical arguments above are exposure criteria and consequence criteria. Messrs. Johnson and Gurule January. 19, 1995 AA~,CO Inactive Drilling Waste Disposal Facility Closure Approval Exposure Criteria: Receptor exposure is considered to be likely when: Contaminant release mechanisms are judged significant, or Containment migration is judged significant, or One or more contaminants are environmentally persistent. If exposure is found to be unlikely, a finding of negligible risk is made on the basis of absence of a likely exposure item and the action plan is evaluated under the Impact/Benefit Evaluation step. The purpose of this step is to determine whether the benefits of taking a corrective action would be greater than the impacts of taking such a corrective action. If any one of the exposure criteria are satisfied, a finding is made that exposure is likely.' Further screening continues to evaluate Consequence Criteria. Cbnsequence Criteria: Adverse consequences of exposure to contaminants from reserve pits are considered to be likely when: (a) The duration or frequency of exposure is sufficient to cause adverse health and environmental effects. This is evaluated by reviewing human and wildlife use patterns at a given waste site, waste site accessibility, and ground and surface water uses. and either: (b) The quantity, or concentration of one or more contaminants exceeds pertinent t'ederal or state water quality criteria or standards protecting health and/or the environment. Measured contaminant concentrations in the water will be compared with health and environmental standards and criteria for each target contaminant, to identify, exceedances. When only human populations are at risk. health criteria are used. When only populations at risk are nonhuman (e.g., fish. wildlife, vegetation), environmental criteria and standards are used: or (c) One or more contaminants exhibit high acute toxicity. The NIOSH toxicity rating system (NIOSH 1974) will be used to identify contaminants highly toxic to mammals. This information will be used to determine whether a target compound exhibits acute high toxicity.. If the duration and frequency term is insufficient to cause adverse effects, there is no need to evaluate the other two consequence criteria, and a finding of negligible risk is made. If the duration and frequency term is sufficient, but neither of the other two consequence criteria Messrs. Johnson and Gurule January 19. 1995 .-KRCO Inactive Drilling Waste Disposal Facility Closure'Approval are met. a finding of negligible risk is made. The action plan is then evaluated under the Impact,.'Benefit Evaluation step. If the duration and frequency of exposure is determined to be sufficient to cause adverse effects and either of the other two consequence criteria are satisfied, then a findin~ is made that adverse consequences are likelv, and the risk at a waste site is said to be significant. If the screening indicates that risk is significant, then the responsible parry shall proceed with implementations of corrective actions. Sites Considered For Closure Based upon the above referenced criteria from the June 1991 INTERIM SITE. ASSESSMENT GUIDANCE FOR INACTIVE DRILLING WASTE SITES. one wellsite has been reviewed for closure: Prudhoe Bav State The decision to grant closure approval on these sires is based in parr on a review of the inactive drilling waste site assessment documents listed below which you have submitted. site visits during August 1994. ana the February. 25. 1994 USGS document that provides technical response to public comments on this site.

The location was clean and free of debris, with the exception of a cable in a pit about an eighth of a mile north of the well bore. Also, there was a pit west of the well bore that needed'to be filled. There'were 3 mounds of gravel and a berm around a fuel tank that needed to be leveled, and a small spot at the south end'of the location that needed to be filled~ The well marker was made and.well dat.a bead welded on a steel plate, but not welded to casing on the well bore yet. Location work above to be performed before I can approve a location clearance. I informed Cold Weather Corporation that all the above fractions had to be performed for a location clearance. I talked to Lonnie Smith and Blair Wondzell about the mud pits north'of the drill site that were not filled, and was informed that ARCO and the State agreed to leave the pits open as grass has grown in and around them. Pictures were taken to verify this rePort. Monday, July 28~ 1986: I went back to Prudhoe Bay State #1 and k0und ~he mounds Were leveled and marker plate welded to the casing stub with the following data: 'ARCO Alaska, Inc., Prudhoe Bay State ~1, 2316' FNL, 1190' FEL, Sec.. 10, Ti"IN, R14E, UM.

Box 100360 Anchorage, AK 99510-0360 Telecopy No. (907) 276-7542 Re: Location Clean-up - Prudhoe Bay State #1 Dear ~. Hart: Prudhoe Bay State ~1 well was originally completed in June, 19~8, .was reworked in November and December' 1970, and has not produced since May, 1970. . 'The location was inspected .in 1983 -- by a Commission representative and an 'ARCO representative -- and it was noted that the pad was in terrible condition with.wood piling protruding above ground level and metal flare line supports still in the flare pits. (See. Detail ~3.) After the 1984 joint inspection, which showed no improvement (see Detail #4), and follow-up letter to ARCO, the well was plugged and abandoned in April, 1985. A joint inspection in 1985 resulted in a work plan being develope, d by ARCO (see Detail #10); but our June 19, 1986 inspection showed that no work had been done on the location (see the attached four photographs), and the abandonment marker as proposed by ARCO (see Detail #7) was apparently not installed. It is incumbent upon ARCO to clean up. this location during this su ~nvner season so that location clearance can be effected this summer. At your early convenience, please advise us as to your plans to effect location clean-up consistent with the scope of work outlined in Detail ~10. ~ionnie C,/ S~ith Commissioner jo/A. BEW. 30 Attachments: Details, Photographs ' . . t ' f Ala a MEMO ~ "'".U ,. ~ ~,sRA M S a~ o s.k TO: ~il rton DATE: June 27 1986 ' C~'ai~ ~ ' h~~-' FILE NO.: D .ADA .130 Lonnie C. Smit TELEPHONE NO.: Commissioner ~~ SUBJECT: Doug Amos Petroleum Inspector THRU: FROM: Abandonment Inspection ARCO Prudhoe Bay St. # Permit No. 67-11 Prudhoe Oil Pool Thur:~day, ~une 19, 1986: I accompanied Mike Lucich, ARCO representative, to conduct the clean-up inspection for the ... abandonment of Prudhoe.Bay State ~1 location. As the attached p~otos show, this location is in very poor condition. Before final abandonment status is granted, I recommend that the Co._mm~issi. on require ARCO to: cut at ground level'" and remove from location all wood and metal pilings; remove all metal debris; use the gravel from..'the flare pit.and from the gravel pad to the west of flare pit to cover the areas where the pilings were cut off; weld plate over casing stub with the operator name, lease name, well number and surface location of well as per AOGCC; 20 AAC 25.120 bead welded to the plate. I filled out an AOGCC Surface Abandonment Report and took photos, of the location. These are attached. In summary, I conducted the clean-up inspection for final abandonment of ARCO's Prudhoe Bay State ~1 well. The location is not in suitable condition for abandonment. Attachments DETAILS - PRUDHOE BAY STATE .~1 · 2~ 3, 4~ ~ 6, Subject well was spudded April 27, 1967 and was completed as the Prudhoe Bay discovery well on June 24, 19~5. During November and December, 1970, remedial work was performed because of bad casing. This work was completed January 4, 1971. On Monday, August 15, 1983 our Petroleum Inspector, Ben LeNorman, inspected this location and noted that the pad was rough with piling protruding through the gravel pad, and the pits were open. Therefore, he recommended that it was in an unacceptable condition to be classified as a suspended location. This was conveyed to ARCO Alaska, Inc. by letter dated September 20, 1983 signed by Commissioner Lonnie C. Smith. Subsequently, ARCO ~equested by Sundry Notice dated October 18, 1983 a one (1) year extension to complete clean-up requirements on subject well. On Sunday, August 19, 1984 our Petroleum Inspector, Bobby Foster, and ARCO's Prudhoe Bay Field Drilling Supervisor, Kirk White, inspected the location and discussed the condition, of the wellhead and the location. ~Mr. White was told that all of the wooden pilinms would have to be cut off below ground level, including tho~e out in the tundra~ all of the trash needed to be removed; the location graded; and the outlets on the' Christmas tree plugged if the well was to be maintained in a suspended status. By letter dated September 20, 1984 to W. S. Congdon, Commissioner Lonnie C. Smith notified ARCO that in spite of his September 20, 1983 letter to ARCO, as of August 24, 1984 "no progress had been made in improving the clean-up of this location which is in poor condition." It further stated: "To complete satisfactory clean-up for suspension, the wooden pilings both on and off the pad will have to'be cut off at or below grade, trash removed, the location leveled, a proper well Sign installed, and the outlets to the Christmas tree plugged." A September 12, 1984 Sundry' Notice from ARCO (received at the Commission October 16, 1984), signed by T. L. Fithian, proposed to plug an.d abandon Prudhoe Bay State #1 by the following procedure. DETAILS page 2 7~ 8~ e 10. . · . Spot 50' cement plug extending to the surface in 7" casing. Install prefabricated blind flange with abandonment post marker per 20 AAC 25.120. Clean up location per 20 AAC 25.170. . Notify AOGCC 24 hours before plug and abandonment. Estimated start: March 1, 1985. This was approved on October 16, 1984 by Lonnie C. Smith. A Sundry Notice dated March 7, 1985, signed by T. L.. Fithian, requested a change from the September 12, 1984 Sundry Notice in that a metal plate be welded onto the top of the wellhead with the required information bead welded onto the top of the plate. This was approved by the Commission on March 11, 1985. On April 13, 1985 Petroleum Inspector Harold Hawkins witnessed the placement of the cement surface plug inside the 7" casing from 50' tO the surface. The marker plate was to be installed later. A "Subsequent" Sundry Notice dated June 4, 1.985 reported the operation as follows: Started P & A operations @ 0600 hfs, 4/12/85. Removed tree. Ran 60' of 1-1/2" tubing and spotted 25 sx AS ll. Cut 13-3/8" casing 5" below pad level. Pumped an additional 25. sx AS 11 (top job). Witnessed by H. Hawkins,. AOGCC. Welded marker on top of 13-3/8" well cap. Spread gravel and cleaned up location. P & A operations completed { 1200 hfs, 4/14/85. On July 26, 1985 Petroleum Inspector Doug Amos inspected the location with ARCO Alaska's Dick Palinko who wrote a memo to Kirk White/Doug Stoltz in which he listed the "Scope of Work" as follows: DETAILS page 3 · · 3, · Flare pit to be backfilled with existing gravel around perimeter to adjacent surrounding ground level, after removing or cutting off metal in pit. Pickup & remove all metal, wood, & debris from entire pad plus 2 burn pits on N. end of location, wood posts to be cut off 6" below ground level & holes baekfilled. ARCO to. provide burnable & metal dumpsters on new Gas Injection Pad in back of CCP for debris removed from clean-up. Excess gravel from flare pit entrance road to be utltzed to cover 2 specific areas where large amounts of metal debris will have to be picked up on S/E corner of pad in a water filled trench and on E side of pad on dry ground. Any gravel left over from burn pit entry road after trench, bad spots, post holes have been covered or filled should be put into old mud pit adjacent to burn pit on W/side of location.,' so that road will be leveled to existing adjacent tundra ground level. Remove a minimal amt of gravel from around casing 'on well & weld an identification plate to casing with appropriate information. This plate will remain exposed until final P & A inspection by AOGCC Rep & photographed by him & then covered with gravel by ARCO. 'ALASKA OJ.i, AND GAS CL;~SERVA'fi~.; ......

This location was again inspected by our representative, Bobby Foster on August' 24, 1984 accompanied by Kirk White, ARCO rep- resentative. 'As of that date, no progress had b. ee.n made in improving the clean-up of this location Which is in poor condition. . To complete satisEactory clean-up for suspension, the wooden piling both on and 'off the pad will have to be cut off at or below grade, trash removed, the location leveled,, a proper well sign installed and the'outlets to the christmas tree plugged.

The slides and thin sections'have ndw been placed in the State's public library of specially prepared .well materials.

The resultant re- servoir fluid exhibited a dev¢ point of 4, 305 psis at the reservoir temp- erature 180°F.

A-7048-a _Analyt!cal Procedure ttydrocarbon Compositional Analyses The samples of separator gas and separator liquid were analyzed by the conven~ lional low temperature distillation method and the results are reported on Page 4 showing both composition of each sample and the computed analysis of the well stream based on the gas-liquid ratio of the primary separator. The separator liquid production was calculated from the measured stock tank production by applying the determ'ined shrinkage factor. · Equilibrium Cell Determinations Following the compositional analyses, portions of the primary separator liquid and gas were phy.sically recombined in their produced ratio in a variable volume, glass-windowed equil{brium cell. Determinations On this mixture were divided into the following two main categories: 1. Dew point pressure determination and pressure-volume relations on a ... constant weight of reservoir fluid at the reservoir temperature. The procedure consisted of establishing equilibrium between gas and liquid phases at a low pressure and measuring the volumes of liquid and gas in equilibrium at that pressure The pressure was then t:~i~ed by the iCijec'tion'0'f mercury into'the ~ell and phase equilibrium established again at the higher pressure. This procedure was repea- ted until all of the liquid phase had vaporized at which point the satura- tion pressure was observed. The cell pressure was then raised above the dew point pressure in order to determine the supercompressibility characteristics of;the single phase vapor. As a check on all readings and particularly to verify the dew point, the cell pressure was incre- mentally reduced, equilibrium establishe~l and volumetric readings made. Reported. on Page 5 are the relative volume relations and specific volumes of the reservoir fluid over a wide range of pressures as well as deviation factors of the single phase vapor above the dew point. Al'so reported on Page 5 are the dew point pressures resulting from recombin'ations at gas-liquid ratios above and below the ratio measured at the time of sampling. II. Compositions of the produced well stream and the amount of retrograde condensation resulting from a stepwise differential depletion. This procedure consisted of a series of constant composition expan- sions and constant volume displacements with each displacement being ... terminated at the original cell volume. The gas removed during the constant pressure displacement was charged to the low temperature fractional distillation equipment for analysis. The produced volumes of reservoir gas, the determined compositions, computed GPM content and respecti of retrograd 8, both in tc carbon pore ye deviation factors are presented on Page 6. 'The volume e liquid resulting from the gas depletion is shown on Page rms of barrels of reservoir liquid and percent of hydro- space.

(Continued) and liquid remaining in the t'eservoir after depletion to abandonment'pressure. Ecluilibrium Flash Calculations The produced compositions and volumes from the depletion study were used in conjunction with equilibrium constants to calculate cumulative stock tank liquid and separator gas recoveries resulting from conventional separation. These data are reported on Page 7 of the rePort. Gas .plant products in both the 'primary separator gas and°the full well stream are also reported, All recoveries are e.xpressed in terms of one MMSCF of well stream fluid in place at de,w pein( conditions.

DESCRIBE PROPOSED OR COMPLETED OPERATIONS (Clearly state all pertinent details, and give pertinent dates, including estimated date of starting any proposed work. This well is completed as a gas well through perforations 8210-8250'. While preparing the well for flow tests, evidence of damage to production casing' was discovered. The well has been killed with 97# oil base mud. We propose retrieving the tubing, then setting a 500' cement plug in the 7" casing. We will then inspect and replace or repair damaged casing strings. We plan:to complete this well with 2-7/8" tubing set in a packer. We are now moving a rig to this location to do the work. C 0 N Fi D"E N T/A L ! 6.

V, Pasher Freeze-out test on North Slope gas sample · Gentlemen: / ~ '-I I '--.- I "]'- Three cylinders of "300 psi inlet" gas were received from Atlantic _ Richfield Company on July 2, 1970. On August 25, 1970, a freeze- out test was run on this gas. ._ The gas was passed at 328 to 142 psia, through a twelve (12) foot stainless steel tube with an inside diameter of 1/16 inch submerged in a temperature bath controlled at -100°F. The inlet and outlet pressures were monitored by Heise gauges during the run. The' differ- ential pressure was alsomonitored by a Pace Engineering Company differential pressure transducer which recorded continuously on a time chart. No plugging occurred a~ter 11-1/2 hours with a total volume of 52.2 cubic feet of gas passed through. Details concerning time, volume, pressure and weight are given in Table 1. The contents of the freeze-out tube were analyzed and showed an increase in concentration of the higher molecular weight hydrocarbons. Compari- son of the composition of the feed gas and the freeze-out sample is shown in Table 2. The freeze-out tube was also extracted with lot methyl ethyl ketone (M. E. K. ). after the run, and the resulting solution cooled to 0°F. for .twenty-four (24) hours. There were no apparent wax c.r..ystals in the M. E.K. solution. The M. E.K. solution~w-~s t~e~ 'evapo-r-~-~e'~-d-~nd~the resulting residue weighed. Figure 1 shows the apparatus used in this freeze-out experiment. We wish to thank you for this opportunity of serving you.

Separator gas and liquid analyses are reported in Tables 1 and 2..The separator liquid analysis was run by Core Laboratories, Inc., Dallas. The calculated well stream.composition, based on the separator pro- ducts analysis and sampling GOR, is l~resented in Table 3. Table 4 is a copy of the report from the Bureau of Mines, Helium Operations, Amarillo, Texa's, giving their analysis of the sample of Pruclhoe Bay State #1 high separator gas which we sent them. This sample Was sent to the Bureau primarily for helium determination. We also ran the GOR and shrinkage of the separator liquid in.the lab, and the results of these tests are listed in Table 5. .. The field determined hydrogen sulfide and carbon'di'oxide content of the gas were reported in J. Cain's letter No. 02-111 dated 7/23/70. For completeness the fieldacidgas results have also been repokted in Table 1'. ,. , We have sent to P-V-T, Inc., Houston, for wax freeze out'tests several 'containers of high pressure separator 9as fr6m the subject well. Their tests are in 'progress, and we will send out' the results when we 9et their report' The calculated wel.1 stream compositions reported in 'Table'.3 are identical except for the heavy ends. In 'one the heavy ends were lumped together as heptanes plus, while in the other, the Hypercal distillation of the heptanes p'lus fraction in Table 2 was used. Helium and hydrogen sulfide were not included in'the well stream composition. Also, I added the 0.2% distillation loss to the heptanes and assumed that the heptanes plus in the gas was all heptanes. Please advise if you have any questions about these tests or analyses. W. V. Pasher' sj Attachments 01-223 cc: Cecil Chapman, Anchoraqe, Alaska 'A. R. Cast0e, Dallas, Texas H. R.

The gas was~ dehydrated to a measured i'~i'-.'."~0°F dew'." 'point. On April 6 around noon the flow became erratic and the Well shut-in. Otis Wire Line set up on well and found plug at approxi- 700'. Cement, mud, formation sand, and hydr~ates were recovered bailing. This data shows that the well had not been completely i..¢~eaned up. The sand, mud, and cement formed a restricting orfice caus- .."lng pressur~ and temperature drops; thus, reaching hydrate formation tem- '"".'~'.. .pe'rature. The hydrates acted as a binder; thus, plugging well Attempts "..'." .:',i..'. with methanol and "ice picks" were made to break the plug. Finally on '.April ~0, the "ice plug" was disintegrated and the well opened up. The "'separator was bypassed, and the well flowed in excess of 5MMSCF/D for , cleanup. During this flow rate the stream temperature at heater lowered '. and hydrates formed in the heater; thus, shutting well in. On May 2 at .... ' .noon the hydrates were cleaned out and the well opened again. At approxi- · mately 8:~0 A. M., May ~, the well stabilized, and tests began at 10:20 A.M. Separation conditions were 1015 psig and 74°F. The gas stream was .sent through the glycol dehydrator and gas measured downstream of the dehy- .. ..drator. The well flowed in a stabilized condition from 8:~0 A. M., May ~, to 10:'00 P. N., May 5. At this time the well was shut-in because of weather conditions. It is my opinion that since the well .has been'cleaned up, .the well can now be flowed without plugging. All G0R data, sampling, and ['.". other analytical data was collected and witnessed by me. This data is pre- . , ."...'... sented in attached tabular form. "i... '.:!!!.. .: ". Prior to testing and immediately after shutdown the gas flow meter static .'.." .'"' .pressure was checked using a dead weight tester. The flow meter differen- ' ....,'.~:~."' rial pen was checked with a Meriam Portable Field Manometer. Both static ..." and differential pens were in calibration throughout the pressure ranges. ..... ~,. The orfice plate was also checked to ascertain that it was a ~.00 x 1.750 . .:'..,,'.': .Plate. After shut-in, we removed the Floco Meter and sent it to Anchorage. .".' . Here it. was tested by the Ace Tank Co. ARCO's Mr. Winston Toliver wi.tnessed . this test.

Dear Shareholder: During the past year Atlantic Richfield Company has been engaged in joint exploration with Humble Oil and Refining Company on a 90,000-acre block on the North Slope of Alaska on the shore of the Arctic Ocean at l~rudhoe Bay, which is some 390 miles north of Fairbanks and 150 miles southeast of Point Barrow. Results of this exploration venture have been announced publicly as information became availnble. Our first well, the Prudhoe Bay State No. 1, had 470 feet of gross sand, . primarily gas, but with some oil at the bottom. The upper 30 feet of this Triassic sand tested 40 million cubic feet of gas per day. The lower 14 feet of the same sand tested at rates up to 2,415 barrels of oil per day. We~. Z.. >.~ .......... also tested oil in the Mississippian Carbonate formation from 9,505 to . 9,. 825 feet and the flow rate was 1,152 barrels per day. ~ The second well, the Sag River State No. 1, is located approximately 7 mile's southeast of the first well. We announced on June 25 that the well had cored over 200 feet of oil sand in the Triassic zone. Sabsequent coring and testing · in this second well indicated approximately 300 feet of net oil sand. The bottom 15 feet of this sand tested at a rate of 2,300 barrels of oi.1 per day, with a gas-oil ratio' of 635 to 1, gravity 26.8° Alii, and pour point of minus 10° F. We believed that with the information obtained from this recent coring and testing, a sufficient basis existed for an independent evaluation of the .possible potential' of this discovery. To secure such an independent evaluation, we asked DeGolyer & MacNaughton, a recognized oil consulting engineering firm, to review 'our information. Their letter to us reads as follows: .Mr. L. F. Davis Executive Vice President North American Producing Division Atlantic Richfield Company P. O. Box 2819 Dallas, Texas 75221. July 16, 1968 Dear Sir: Pursuant to your request, we have reviewed the available geology, geophysics, · well logs, recent tests, ,. , .. , , . , and other pertinent data relating to your recent discovery in the general area of Prudhoe Bay, which is on the Arctic Slope adjacent to the Arctic Ocean. This field is some 800 miles north of Cook Irdet in the State of Alaska. In our opinion this important discovery could develop into a field with recoverable reserves of some 5 billion to 10 billion barrels of oil which ~vould rate it as one of the largest petrole, um accumulations known to the world today. This is an entirely new oil province for North America. The major part of the field appears to lie on a 90,000-acre block 'of.leases in which Atlantic Richfield Company and Humble Oil and Refining Company each owns a 50% working interest. Two wells seven miles apart have been drilled to date on this block. , . The estimate of 5 billion to 10 billion barrels is a reasonable expectation for a structure o2 the size indicated by seismic interpretation with the sand characteristics and saturation which have been shown by the productive intervals in the two wells. Very truly yours, DeGolyer and MacNaughton We will continue to drill on the Sag River State No. i until the lower formations are reached which were encountered in the first well. We are planning a drilling program for next winter, invoIving the use of three drilling rigs. We have also undertaken a series of pipeline and transportation studies to determine the most efficient way to bring this oil to market. Commercial development of the field will require a minimum of three to four years. Robert O. Anderson Chairman of the Board , Thornton F.

I traveled with Mr. Jerry Tricksy, production superintendent for Atlantic Richfield Company, while in route to witness a test on the subject well. We caught a Sea Airmotive charter flight to Atlantic~s Sag River ~1 location and traveled from there by company chartered helicopter to the Prudhoe Bay location, arriving there at approximately ll=50 a.m. Upon our arrival we found the well to be shut-in, and after discussing previous. test data available on location, it was decided that best test results, for our purposes, could be obtained by rearranging' the separator vent lines, Work was completed and a closed-in tubing pressure was obtained by a dead 'weight tester. The closed-in tubingpressure was 3,102 psig. Due to the type of test desired, the well was opened to a 1/4" adjustable choke which was sradually increased to 28/64. Although the choke had been calibrated previously, there is reason to believe the calibration was not accurate. A. flow rate of 7.3 million cubic feet per day was obtained with 'a flowing tubingpressure of 2,200 psi. Rate was main- tained for one and three-quarter hours when..hydrate formation started blocking the tubing. The flow rate decreased considerably in a matter of five minutes and well.was shut-in. :. Mr. Trickey and I traveled by helicopter to the Dew Line station at Ooliktok where we talked to Mr. Lee Wilson of A~CO's Anchorage office by phone. Mr, Wilson was advised that I would like to see a complete four-point test, but if these problems could not be 'alleviated, I would recommend to the Committee that the information obtained thus far be accepted as a test providing AKCO furnished 'us with notarized results of a drill-stem test made previouslyw~th a bomb..i2"'the hole. Mr. Wilson was agreeable and advised Mr. Tricksy to make one other attempt to test the well. . We returned to location and opened the well at 10=20 p.m. on a'l/2" positive choke with a closed-in tubingpressure of 3,110 psi and a wellhead temperature of 39oF. Tubing pressure bled to 1,400 psi in one minute then to 350 psi after two minutes, with wellhead temperature dropping to 20°F. It was obvious tubing was essentially blocked solid with ice. Well was closed-in and operator released drilling rig in preparation for shut-down for the summer. Due to the confidential nature of information being obtained on North Slope wells, Atlantic had forwarded essentially all data to the Anchorage office and very little information was available on location.except that which developed whtle I was there. The Anchorage office will supply' us with other needed data next week. It is our understanding that only three people in Atlantic~s Anchorage operations have access to all data developed'on this well thus far. Also, in this connection, an extremely "tight-hole" situation has been imposed on data from their Sag River ~l. Outsiders are not permitted to leave their airplanes ... Harry W.

Due to transportation and weather problems, we did not leave the location until 3:30 a.m., June 27, returning to Fairbanks by the same means of transportation used to travel to the location.

VonderAhe Petroleum Engineer SUBJECT; Field Trip Report - Atlantic Richfield Company Prudhoe Bay ~/1 · On April 30 I left Anchorage at 8:00 a.m. via Northern Consolidated Airlines in route to Fairbanks with Chris Woesner, Petroleum Engineer for Atlantic Richfield. There we met Jim Williams who went with us in an Interior Airways plane chartered by Atlantic Richfield Company, arriving at Prudhoe Bay ~1 at 12:25 p.m. Drill stem test ~;8 was under wa_y_~the tool havi~ been opened first at 3:05 p.m. the day befor_e~/'~'~%-6~--fi~e'~inut~s~ it was cloSed-in fg~"-'g~e"'~gur ................ " ....... ~0r~-~-h~ init{al '~sgure, then opened at 4:09 p.m. Blow varied from weak to strong and back to weak again until the .tool was closed at 12:26 p.m. on April 30 for final shut-in pressure. Pulled free at 4:26 a.m.,.,May 1, after a sixteen homr closed-in period. Recovered a little oil, 500' of water cushion, 1,840' of rat-hole mud, and 3,804' of water. Salinity: top, 1,600; middle, 2,000; bottom, 5,100 ppm. On May 2, 1968, ran cement retainer to 9,665' and squeezed perforations with 125 sacks of cement. Started taking fluid 1,200 psi @ two barrels per minute. Twenty barrels to formation at 1,600 psi. Built up to 2,600 psi. Second stage (cement) 2,600 to 3,400 psi then on up to 4,000 psi. Held pressure for five minutes then pulled up to reverse out. Built up to 1,800 psi when casing gave way. Pulled out, found twenty joints drill pipe full of cement. Closed- in and applied pressure at surface. Could not build up pres:sure beyond 175 psi, showing casing had ruptured. Attempting to locate rupture ~ith packer but were unsuccessful by ~fternoon. ..: As it would be a matter of days after the leak was located before it could be repaired and the next stage perforated .for a test, returned home on the 'evening of May 2 via same route and airlines, arriving home at 8:45 p.m. As this well is still on a..":tight hole" basis, I am not including depths of this or other tests in this report, though I have a complete history of all tests made if you wish to study them confidentially.

A reservoir fluid study was performed using these samples, and the results of the study are pre- sented on the. following pages. The separator products were physically recombined in ihe reported producing ratio of 18,011 standard cubi. c feet. of separator gas per Carrel of separa!or liquid at 60° F. ']7he gas and liquid compositions were measured and used in conjunction with the pz'0du¢:ing raf..l:.o to calculate the we!.l stream compo- sition. The remainder of the study was pe..rfor'med wi~,h the recombined fluid sample. The fluid was c:ha_~.ged to a visual cell and heated to th(' reservoir' t. emperatu~e of 180° F. The .(luid was a]lo~ve.d to g~adua!~y' expand at this temperature and a retrograde dew po.-,'..at was observed at 4322 psia. This is extremely near the reported reservoir p~essu~e q£ 4~05 p$ia.
