o>r r • THE STATE Department of Environmental 011-1LASKL'1 GOVERNOR SEAN PARNELL RECEIVED FEB 0 7 2014 February 4, 2014 A0GCC Certified Mail, Return Receipt Requested Article No.: 7012 2210 0002 1216 2391 Wayne Svejnoha BLM — Division of Resources 222 W 7th Ave, #13 Anchorage, Alaska 99513 Conservation Division of Spill Prevention and Response Contaminated Sites Program File: 320.38.010 SCANNED 0 2 2014 Re: Potentiall Responsible Party Notice Letter and Information Request NPRA Legacy Wells - General Hazard ID: 26125 Ledger Code: 14339387 Dear Mr. Svejnoha: 610 University Ave. Fairbanks, Alaska 99709-3643 Main: 907.451.2181 Fax: 907.451.5105 This letter is to advise you that the Alaska Department of Environmental Conservation (ADEC) has identified the 136 legacy wells within the National Petroleum Reserve in Alaska (NPRA) as potential contaminated sites. Some of these wells require extensive cleanup of oil and other hazardous substances released to the environment. Since you are identified as a current or past owner and/or operator of these sites, please be advised you may be financially responsible or liable for the investigation and /or cleanup of any hazardous substance contamination that might be present. Alaska Statute 46.03.822 establishes who is liable for contamination. Records available to the ADEC indicate that you meet one or more of the following criteria: » owned or controlled the hazardous substance at the time of its release; » own(ed) or operate(d) the property or facility from which the release occurred; » owned or operated property at which the hazardous substance came to be located; and » arranged for transport, disposal or treatment of hazardous substances that were released. Site History From 1944 through 1982 the US Government drilled 136 wells to explore for oil and gas resources in the NPRA. It is our understanding that other federal agencies and some private companies may have operated or managed these sites in the past. We have also been informed that 23 of these well have been conveyed to public and private entities. The ADEC currently lists 14 of the 136 legacy wells on our database of contaminated sites. The Bureau of Land Management (BLM) is identified as the responsible party for the following sites. Wayne Svejnoha 0 2 February 4, 2014 • BLM Cape Halkett Drill Site (File # 300.38.108) • BLM East Simpson #2 (File # 300.38.109) • BLM East Teshekpuk Drill Site (File # 300.38.110) The U.S. Army Corps of Engineers, under the Formerly Used Defense Sites program, is working with ADEC under the Defense States Memorandum of Agreement on cleanup actions at the 11 Umiat test well sites. BLM is identified as the landowner in our records, and as such is identified as a potentially responsible party in addition to the Department of Defense: C Umiat Test Wells 1-11 (File # 335.38.001) The information contained in these files is part of the public record. Our databases are accessible on the Internet at: http://dec.alaska.gov/spar/csp/db_search.httn Additional Actions Needed ADEC sent a letter on July 11, 2013, identifying an additional 15 legacy well sites with confirmed releases (enclosed). As stated in the letter, ADEC recommends that BLM develop a plan to address known, suspected, and unknown releases at the legacy well sites, in coordination with the appropriate regulatory agencies. We expected a response to this letter before now. Please respond to this letter within 30 days. After we receive and review your response we will determine what additional actions will be taken regarding each site with known or suspected contamination. In addition, with your response, please complete and return the enclosed questionnaire requesting more information about past operators. In accordance with Alaska Statute Title 46, ADEC is authorized to provide regulatory oversight for any contamination response efforts initiated by the responsible party. However, if response actions by the responsible party are not satisfactory to ADEC, we may then assume the lead role in the investigation and cleanup efforts. In the event that State response actions are necessary, the responsible parties may be held financially liable for any response actions taken by the State. Alaska Statutes 46.04.010 and 46.08.070 establish cost recovery procedures for certain costs, including oversight activities, incurred by the State in responding to pollution incidents. If you are determined to be a responsible or liable party, ADEC may bill you at a later date for our expenditures associated with this pollution incident. Expenses for which we may seek reimbursement include: Staff time associated with general or technical assistance; work plan review; project oversight; general project management; legal services; interest; travel; equipment and supplies; and any contracting costs. Pursuant to Alaska Statute 46.08.075, the State may also file liens against all property owned by a person who is responsible or liable for State expenditures. Please respond in writing within thirty (30) days from the date of this letter addressing your intended actions with respect to this pollution incident. If you believe someone else is responsible for this pollution incident (e.g., a past owner or operation of the site) or if you have any questions concerning this matter, please contact Mr. Fred Vreeman at (907) 451-2181. The attached "ADEC Information Request" describes the minimum information expected in your response. Additional information may needed to evaluate the risks and responses required at each legacy well site.

ADEC has also reviewed the response by the Alaska Oil and Gas Conservation Commission (AOGC). We concur with the response by ACIGC and have no further comment regarding the priorities. We do have comments about the investigation and cleanup plans presented in the report. With this letter we arc outlining regulatory requirements related to the environmental work that is proposed and required as part of these cleanups. ADEC is concerned that the 2013 Legacy Wells Strategic Plan prepared by the BLM does not include either assessment of the contingency for assessment of known, likely, or unknown but possible contaminant releases. In addition, BLM plans for surface cleanup of these wells should be made clear in the plan. At least one of these legacy wells has extensive PCB contamination and has resulted in a multi-year cleanup totaling tens of millions of dollars. At others, solid waste disposal practices have resulted in releases to the environment with estimated cleanup costs in the hundreds of millions. Known releases documented in the records we reviewed include crude oil, gasses, refined oil and fuel, drilling fluids that include various organics, metals, and other chemicals, and unknown contaminants from drums and other containers observed to be damaged and abandoned at the various well sites. There are 13 legacy well sites with known releases currently on the DEC contaminated sites list. Many of these are in the process of being addressed, cleaned up, and closed. From our Waited records review there are 15 additional legacy well sites with confirmed releases. These should be prioritized for initial records reviews and then added to the BLM contaminated sites list under our cooperative agreement. Suspected releases include fuel releases from operations, storage, and fuel spills at the sites, impacts to various surface water bodies from spilled fluids during drilling and breaches of containment at reserve and flare pits, continued surface runoff from drilling fluids uncontained at several sites, and down -hole substances that were ejected from the holes over time or during blowouts or drilling operations. 1 Wayne Sve noha ? July 11, 2013 Y The.BLN-1 plan to address these known, suspected, and unknown releases at legacy well sites is notably absent from the documents presented to date. The three primary regulatory agencies that need to be involved in the plan are ADEC — Contaminated Sites, Alaska Oil & Gas Conservation Commission, and ADEC — EH/Solid Waste. Other agencies will need to be consulted. as well. Below we provide recommendations for a coordinated plan using the Uniform Federal Policy for Quality Assurance Project Plans (UFP-QAPP) that will involve all of the regulatory agencies in one coordinated manner. This will allow BLM to address these sites in a consistent and coordinated project which fulfills all of the regulatory requirements so that the sites do not need to be re -visited in the fu=e xvhen they are closed after this project. Attached are our comments on each specific well. The acronyms used on the list include terms that are typically used in a CERCLA type investigation however they are also suitable for investigations conducted under the State of Alaska cleanup rules. These include the following; Historical Records Review (HRR) 'chis is recommended for almost all of the well sites. Much of the information required for these reviews is already contained in various reports and appendices or in BLM files. The Historical Records Review should document the type of releases that might have occurred from drilling operations as well as historical use of the site, and should capture all available information on the drilling fluids used and any product produced or released. Preliminary Assessment (PA) This is recommended for almost all of the well sites. A Preliminary Assessment is a limited scope investigation that provides an assessment of information about a site and its surrounding area to distinguish between sites that pose little or no threat to human health or the environment and sites that require further investigation. The PA is a CERCLA defined document and typically does not require sampling. Site Inspection (SI) If the PA recommends further investigation, then an SI is necessary. The SI is a CERCLA defined document, and it is analogous to an initial report of contamination under state cleanup rules. On some legacy well drillings sites it is evident now that an Sl is required just from a review of the reports. An SI investigation typically includes the collection of samples to determine what contaminants are present at the site and whether they are being released into the environment. An approved site specific workplan is required under both CERCL-A and 18 AAC 75 prior to SI sampling. The SI typically is not intended to develop a full site characterization, but is limited to determining the presence or absence of a release. If contamination is found after completion of the HRR, PA, and SI then a RI/FS under CERCLA, or a Site Characte-rizatiowlteportandcleanup-Alas,under-l-fi-AAC7iis`required. -- ----- - -- — --------- - DEC recommends that BLM incorporate into the strategic pian the processes outlined in this letter. A team of agencies composed of AOGC, DEC -CS, EPA as required, and DEC -EH should address regulatory and technical requirements for these well closures. By cooperating and working together with the regulatory agencies BLM will save time and expense, and regulatory uncertainties will be avoided. The strategic plan should reference a project to prepare a generic workplan. DEC suggests that BLM utilize the generic UFP-QAPP workplan format for the required environmental work. If properly prepared, the workplan could encompass most of the investigations and cleanups required at these sites over multiple years. At other multi -site projects we have found this to be an effective way to reduce uncertainties and risk in these types of investigations. A very small site specific FSP could then be developed as BLM approaches each drilling site. Regulatory decisions made during workplan development would provide more certainty in the planning process for cleanups.

ADEC has also reviewed the response by the Alaska Oil and Gas Conservation Commission (AOGC). We concur with the response by AOGC and have no further comment regarding the priorities. We do have comments about the investigation and cleanup plans presented in the report. With this letter we are outlining regulatory requirements related to the environmental work that is proposed and required as part of these cleanups. ADEC is concerned that the 2013 Legacy Wells Strategic Plan prepared by the BLM does not include either assessment or the contingency for assessment of known,likely, or unknown but possible contaminant releases. In addition, BLM plans for surface cleanup of these wells should be made clear in the plan. At least one of these legacy wells has extensive PCB contamination and has resulted in a multi-year cleanup totaling tens of millions of dollars. At others, solid waste disposal practices have resulted in releases to the environment with estimated cleanup costs in the hundreds of millions. Known releases documented in the records we reviewed include crude oil,gasses,refined oil and fuel, drilling fluids that include various organics,metals,and other chemicals, and unknown contaminants from drums and other containers observed to be damaged and abandoned at the various well sites. There are 13 legacy well sites with known releases currently on the DEC contaminated sites list. Many of these are in the • process of being addressed,cleaned up, and closed. From our limited records review there are 15 additional legacy well sites with confirmed releases. These should be prioritized for initial records reviews and then added to the BLM contaminated sites list under our cooperative agreement. Suspected releases include fuel releases from operations, storage, and fuel spills at the sites,impacts to various surface water bodies from spilled fluids during drilling and breaches of containment at reserve and flare pits, continued surface runoff from drilling fluids uncontained at several sites, and down-hole substances that were ejected from the holes over time or during blowouts or drilling operations. , Wayne Svejnoha 2 July 11, 2013 The BLM plan to address these known, suspected, and unknown releases at legacy well sites is notably absent from the documents presented to date. The three primary regulatory agencies that need to be involved in the plan are ADEC —Contaminated Sites,Alaska Oil& Gas Conservation Commission, and ADEC—EH/Solid Waste. Other agencies will need to be consulted as well. Below we provide recommendations for a coordinated plan using the Uniform Federal Policy for Quality Assurance Project Plans (UFP-QAPP) that will involve all of the regulatory agencies in one coordinated manner. This will allow BLM to address these sites in a consistent and coordinated project which fulfills all of the regulatory requirements so that the sites do not need to be re-visited in the future when they are closed after this project. Attached are our comments on each specific well. The acronyms used on the list include terms that are typically used in a CERCLA type investigation however they are also suitable for investigations conducted under the State of Alaska cleanup rules. These include the following; Historical Records Review (HRR) This is recommended for almost all of the well sites. Much of the information required for these reviews is already contained in various reports and appendices or in BLM files. The Historical Records Review should document the type of releases that might have occurred from drilling operations as well as historical use of the site, and should capture all available information on the drilling fluids used and any product produced or released. Preliminary Assessment (PA) This is recommended for almost all of the well sites. A Preliminary Assessment is a limited scope investigation that provides an assessment of information about a site and its surrounding area to distinguish between sites that pose little or no threat to human health or the environment and sites that require further investigation. The PA is a CERCLA defined document and typically does not require sampling. Site Inspection (SI) If the PA recommends further investigation, then an SI is necessary. The SI is a CERCLA defined document, and it is analogous to an initial report of contamination under state cleanup rules. On some legacy well drillings sites it is evident now that an SI is required just from a review of the reports. An SI investigation typically includes the collection of samples to determine what contaminants are present at the site and whether they are being released into the environment. An approved site specific workplan is required under both CERCLA and 18 AAC 75 prior to SI sampling. The SI typically is not intended to develop a full site characterization, but is limited to determining the presence or absence of a release. If contamination is found after completion of the HRR,PA,and SI then a RI/FS under CERCLA, or a Site Characterization Report and cleanup plan under 18 AAC 75 is required. DEC recommends that BLM incorporate into the strategic plan the processes outlined in this letter. A team of agencies composed of AOGC, DEC-CS, EPA as required, and DEC-EH should address regulatory and technical requirements for these well closures. By cooperating and working together with the regulatory agencies BLM will save time and expense,and regulatory uncertainties will be avoided. The strategic plan should reference a project to prepare a generic workplan. DEC suggests that BLM utilize the generic UFP-QAPP workplan format for the required environmental work. If properly prepared,the workplan could encompass most of the investigations and cleanups required at these sites over multiple years. At other multi-site projects we have found this to be an effective way to reduce uncertainties and risk in these types of investigations. A very small site specific FSP could then be developed as BLM approaches each drilling site. Regulatory decisions made during workplan development would provide more certainty in the planning process for cleanups.

Foerster Commissioner Alaska Oil and Gas Conservation Commission 333 W. 7th Avenue, Suite 100 Anchorage, Alaska 99501-3539 Re: 20 MC 25.300 (Request for Information)—Status of Oil and Gas Wells Dear Ms. Foerster, This letter is in response to your request concerning the status of the North Slope Borough, (NSB), Gas Wells SB - 8, SB - 11, EB— 15 and EB— 19. Currently all four wells are suspended. The NSB plans to drill several wells in both the East Barrow and Walakpa gas fields in 2010 and 2011. As part of the drilling program we tentatively plan to plug and abandoned Wells SB-8, SB-11, SB-13, EB-15, EB 19, EB 20, and NSB-2. As our drilling program firms up I will be able to provide you with our final plan and schedule. In addition we are still evaluating returning well SB-9 to production and reworking Well EB-21. Attached is a chart of the BGF wells showing their current status and our future plans. Wells that are already plugged and abandoned are not included in this chart. If you are in need of addition information you can contact me at 852-0285 or at kent.arinade @north- slope.orq Sinc y, Kent M.

RE: Husky/U.S.N. South Barrow #14 Sec. 25, 22N/17W, U.B.M. North Slope, Alaska FINAL MICROPALEONTOLOGICAL REPORT The following final micropaleontological report is based on picking, examination and checklisting of 72 ditch samples covering the interval 53 feet to 2250 feet. Enclosed you will also find a 1" to 100' faunal distri- bution log, a faunal checklist and a sketched correlation chart comparing this well with the South Barrow #'13 well. Below is a generalized age summary of the South Barrow : : 14 well. 53-80' A thin deposit of shallow water sediment caps the early Cretaceous in this well. Elphidium acutum, E. clavaturn and E. bartletti characterize this interval. These strata probably represent inner neritic Pleistocene deposition.

The faunas found in the uppermost portion of this interval (above 500') probably represent middle to outer neritic deposition. Faunas occurring between 500 feet and 1000 feet suggest a gradual deepening from middle neritic to possibly upper bathyal depths. Due to the low abundance and poor preservation of the faunas below 1000 feet all that can be said about the environment of deposition is that it was probably marine, but there is not enough evi- dence to tell whether it represents very shallow or very deep marine deposition. It has been suggested that high latitude faunal diversity and abundance diminishes in both directions from the shelf edge. Two possible local correlation points occur at 110 feet and 410 feet which appear to be recognizable in the South Barrow #12, South Barrow #13 and Iko Bay #1 wells. -2- ANDERSON, WARRE.SSOCIATES, INC. . ------~-_._- ----~----~---~-----~~._._----------_._--~~ _m____________··____ --------.. ----------- RE: Husky/USN - South Barrow #14 80-13701 (con It.) AGE: ENVIRONMENT: Aptian to Albian Uppermost Portion - Middle to Outer Neritic Middle Portion - Middle Neritic to Upper Bathyal Lowermost Portion - Probable Marine 1370-1750' This interval is characterized by occurrences of the follow- ing species: Bathysiphon scintillata, Gaudryina tappanae, G. tailleuri, Recurvoides sp., Haplophragrnqides duoflatis, H. inflatigrandis, H. goodenoughensis and arenaceous spp. These species suggest a Neocomian age for these strata. This interval correlates with the unit called Neocomian to Late Jurassic in reports on the South Barrow #12 and Iko Bay #1 wells. After examining and comparing Foramini- fera and Palynomorphs from several wells to the east we now feel that this assemblage is best assigned a Neocomian age rather than a Late Jurassic age. The dominantly agglutinated nature of this assemblage sug- gests that it was deposited in turbid waters. The rela- tively good abundance and diversity indicate a probable outer neritic to upper bathyal depositional site.

This interval is the same as the interval called Jurassic (undifferentiated) in earlier reports on the South Barrow #12 and Iko Bay #1 wells. The depositional environment of these strata could have been as shallow as middle neritic or as deep as middle bathyal.

BE: Eusky/USN - South Barrow ,14 1750-1900' This ass~~blage contains forms suggestive of t~e Late Jurassic but it could conceivably still be Early Creta- ceous, so we have had to spread the age to reflect this uncertainty. This interval is the same as the interval called Jurassic . (undifferentiated) in earlier reports on the South Barrow #12 and Ixo Bay #1 wells. The'depositional environment of these strata could have' been as shallow as middle neritic or as.deep as middle bathyal.

"In terms of Prudhoe Bay and things like that, it's not a big strike," Lt. Cmdr. Anthony Corcoran said yesterday. "In terms of supplying Barrow and the Naval Artic Research Lab, it is significant," The well was spudded Jan. 27 by the Navy's operator on the reserve, Husky Oil NPR Operations Inc. Corcoran said the firm tested a gas sand equiva- lent to the Barrow sand but in a new reservoir. He said the flow rate through a three -eighths -inch, choke was about 2.4 million cubic feet per day, with an open flow potential of about 7 million cubic feet per day. "It's not something we'd build a commercial line to export or anything like that," he said, but "it will help insure a continued gas supply for the Barrow area." Gas sands on the 23 million -acre reserve already are being used to supply the Arctic research lab and Barrow, the northernmost community in the United States. TI".4 %_ -I '? -'? ? " i .

March 18, 1977 MEMORANDUM TO FILE - SOUTH BARROW WELL NO. 14 SUBJECT: Pressure Buildup Survey and Open Flow Potential Analysis I. Pressure Buildup Analysis A. Summary of Results: 1. Initial reservoir pressure is extrapolated to be 963 psia. 2. The kh product has been calculated to be 346.28 md. ft. 3. Assuming s productive thickness of the main producing sand is 22' from the logs, the calculated average permeability to gas 1s 15.74 md. 4. The average calculated mobility of gas is 1356.90 md.1 cp. 5. The skin effect calculated 1 hour after shut in is -1.78. The corresponding pressure difference is -23 psi. 6. The effective wellbore radius is calculated to be 1.48 ft. 7. The actUal reservoir productivity index is calculated to be 17.32 KCFD/psi. 8. The order of magnitude radius of investigation for the transient pressure buildup is calculated to be 270 ft. B. Discussion: The bottomhole pressure buildup survey on the South Barrow Well No. 14 was conducted as a 72 hour shut in commenced after a stable flow period of 10 hours, following and as a part of the Open Flow Potential Test conducted on the well. The pressure data was recorded on Amerada pressure gauges run on wireline and hung in the well opposite the main producing sand. The raw data is presented in Cameo report for the subject well and test. Further analysis of the data was necessary to define the pressure buildup response. The data analysis procedure is outlined below. The data were replotted in the conventional gas analysis manner and are attached as figures 1, 2, and 3. Critical properties of the gas were calculated from the gas compositional analysis of samples from DST NO.1, analyzed by Chemical and Geological Laboratores of Alaska, Inc. Since the production history of the well prior to shut in had consisted of several flow rates, the multiple rate history was incorporated into the analysis. Figure 4 depicts the rate, time history of the well. I-I . . c. Results: 1. The initial reservoir pressure of 9&3 psia was derived from the extrapolation of the curve of figure 3. The value agrees with the final measured values obtained during the final 26 hours of the pressure buildup. 2. From analyais of the slope of the straight line portion of the buildup. the kh product was calculated to be 346.28 DId. ft. Average reservoir flowing temperature and pressure were used to calculate the average physical properties of the gas. 3. The calculation of average permeability requires the assumption of a productive thickness and the require- ment that the total production come from this thickness. Log analysis indicates the thickness of the main productive sand to be 22 ft. As a result, the calculated average permeability to gas is 15.74 md. 4. The average mobility to gas is calculated to be 1356.90 DId./cp. at average reservoir flowing temperature and pressure. 5. The calculated skin effect is -1.78, and the corresponding pressure difference is -23 psi. Since the well had been recently drilled and not subject to stimulation treatment, it is unlikely. that a negative skin should be evidenced at this time. However, the determination of the s1dn is a function of the flow rate and pressure distribution around the wellbore. As such. it is sensitive to the completion scheme employed. Since the well is completed with a slotted liner type completion, other intervals are open to pro- duction besides the main sand. This being the case, the assumption that the entire production is attributable to the main sand may be slightly in error. Minor production may be derived from other zones. resulting in an abnormally low skin calculated in the main sand. Qualitative inspection of the buildup curve indicates that: some small layering effect. probably in the absence of cross flow. is present with a reservoir preasure nearly the same as the main sand. 6. As a result of the above. and assuming for practical pur- poses that the entire production is attributable to the main sand, the effective wellbore radius is calculated to be 1. 48 ft. 7. Tbe reservoir productivity index is calculated to be 17.32 HCFD/psi. 8. Using the van Poolen equation as an order of magnitude estimate, the radius of investigation for the transient 1-2 . . pressure buildup is calculated to be 270 ft. It must be remembered that this is an estimate only. II. Open Flow Potential Analysis A. SUllllllary of Results: 1. The Absolute Open Flow Potential of the Well is 3.700 MCF!D. 2. The exponent (n) of the back-pressure curve is 0.56. ~ The angle of the slope of the back-pressure equation .). is 60.950. B. Discussion: The Open Flow Potential Test was conducted as a multi-point stabilized back pressure test. Kinor problems were encountered with hydrate formation but were overcome without incident by lubricating alcohol and blowing down as required. Flow measurements were taken by means of a 21n. critical flow prover. Bottomhole flowing pressures were calculated from flowing surface pressures by means of the Smith Equation. at average values of pressure. temperature and physical properties. Reservoir pressure was determined from the pressure buildup analysis discussed previously. The data were plotted and analyzed using the conventional multi- point back-pressure analysis and plot and is attached as figure 5. C. Results: 1. Data used in plotting back~pressure curve.

Conclusions The testing equipment and procedures were adequate to effectively determine the basic reservoir properties and to determine the Open Flow Potential of the well.

Dmÿden SUBJECT: Drilling Program Barretÿ Area Fiscal Year 1977 ~ ' During the meeting of May 12th which. was attended by Maurice Fishburn, we discussed the shallow prospects in the Barrow area. It is the Operator's understanding that your office will require the drilling of Barrow #13 where the rig is presently located. Assuming that this order does not change, we bave selected one exploràtory location which could be drilled. after completion of Barrow #13~ The recommended location is NW ~, Section 25, Tòt.¡nship 22 N, Range 17 t"1. This location \vill be less than one ~ile east· of the South Barrow #12 well. The South Barrow #12 encountered two good sands on which core analyses were favorable. The upper'sand is pdssibly gas bearing and the lower sand may be oil productive. We have reviewed the information available on the South Barrow #12 and are unable to understand why the lower sand (sag river?) did not yield more oil. We really do not know how the test was attempted and suspect that it is a mechanical failure. I have taken a small sample of the oil from the well and placed it in the refrigerator where it did not congeal at temperatures of around 40 degrees. Judging from the core analyses, it would seem that the reservoir should have given up more fluid than it did. This well is recommended subject to budget limita- tions, repair of the Carwell rig and succe~sful completion of Barrow #13. --------- J~,jD: Ijb íí . } I , .i1. ~"I V i ¡ r !

Allard SUBJ: Potential Lower Cretaceous Pay Intervals - South Barrow Well N~ From log and sample analysis, three Lower Cretaceous sands are present that appear to be hydrocarbon bearing. These sands, between 1575' and 1655', are from 6 to 10 feet in thickness, each separated by 20 to 25 feet of shale. The 10\ver two sands, 1612' to 1621' and 1645' to 1655', are 1,;'lOrthy of testing; whereas the upper sand, 1575 to 1581', is quite sha1y and does not appear to be of reservoir quality. Log calculated parameters on the lower two sands are 21 percent porosity and 25 percent water saturation. These sands are e~ected to produce gas. Mr. Armor Kane's analysis indicates that the upper sand may produce some oil; hmvever, I believe that"'sand is siltier than the lower one. These sands are behind 7" casing and can be easily tested. The cement band is good above and below each sand. These sands also correlate to thinner, less developed sands in South Barrow Well No. 12. ~t is important to note that there could be some disadvantages in testing these sands depending on the final disposition of this well. If the well is to become a gas producer from the Barrow sand, eÀ~osing other sands in the same wellbore could result in crossf1ow if the different zones have signifi- cantly different pressures. Cement squeezing cannot be considered a permanent seal. Should the upper sands produce hydrocarbon liquids, gas handling would be significantly complicated by removing and disposing of the liquids in that particular area. It is recommended that the zones be tested. 1f the zones produce liquids or _are significantly different in pressure from the Barrow sand, the well should be suspended and not completed as'a Barrow sand producer. Each zone should be tested separately. Drillable retainers should be used for zone separation during testing. The reco~~ended perforating interval for each zone is: 1646' to 1654' and 1613' to 1621'. All perforating should be done with casing guns at two shots per foot. The referenced log for perforating is the FDC/CNL/GR dated 2-5-77. . B. R.

REPORT OF ANALYSIS CLAY SWELLING SUSCEPTIBILITY SOUTH BARROW NO. 13 NORTH SLOPE, ALASKA Core samples from 2318-44 feet. PROCEDURE: Due to the low air permeability on all samples that did not contain fractured IIKII, all samples were pulverized and made into a homogeneous composite. A 50 gram sample was placed in a cell and the permeability measured immediately after saturation of the sample with test fluid. Additional permeability measurements were made 15 minutes after saturation and results expressed in % flow reduction. RESUL TS: FLUID City of Anchorage Water(80 mg/l TDS) Calcium Chloride- 1000 mg/l Calcium Chloride- 5000 mg/l Calcium Chloride- 10000 mg/l Calcium Chloride- 20000 mg/l Calcium Chloride-100000 mg/l Sodium Chloride - 1000 mg/l Sodium Chloride - 5000 mg/l Sodium Chloride - 10000 mg/l Sodium Chloride - 20000 mg/l Sodium Chloride -100000 mg/l Potassium Chloride- 10000 mg/l Potassium Chloride- 20000 mg/l Potassium Chloride-100000 mg/l % FLOW REDUCTION 82 46 40 33 29 22 50 42 29 28 21 30 29 22 I REMARKS & CONCLUSIONS: Additional testing was performed utilizing Halliburton 15% HCl plus inhibitor and surfactant. After saturation with fresh water, 3 samples showed no improvement with Halliburton fluid. Analysis on pulverized samples using Baroid diesel base mud showed very 1 ittle invasion after subjected to 3 1/2 hours of testing. ,-~ ~ ~"'" ,. .- ".. , -.. . -~._.~ -2- (Lab. #5292 continued) Conclusions of the above analysis indicate that the formation tested contains a "clayll material that is very susceptible to fresh water. Fluids \:'lith a concentration of 20000 mg/l and higher have the least detrimental effect on these IIcl ays". After the swell i ng has been compl eted it appears to be irre- versible. All tests indicate drilling with a diesel based mud should prevent any additional damage caused by these swelling "claysll. [it ~K!] . . I IL ff.9!X! ~Mn1, k r .. .~ - .

". I r Hay 14, 1976 TO: LCDR Terrence J. l~oods , Officer in Charge, NPR #4 FROM: ~. w. Do~..¡den SUBJECT: Drilling Program BarretV' Area Fiscal Year 1977 'During the meeting of Hay 12th which. was attended by Maurice Fishburn, we discussed the shallow prospects in the Barrow area. It is the Operator's understanding that your office will require the drilling of Barrow *13 where the rig is presently located. Assuming that this order does not change, we have selected one explorâtory location which could be drilled. after completion ~f Barrow #13~ The recommended location is ~~v ~, Section 25, To,.¡nship 22 N, Range 17 11. This location \vill be less than one ~ile east-of the South Barrow #12 well. The South Barrow #12 encountered two good sands on which core analyses· \V'erefavorable. The upper' sand is pdssibly gas bearing and the lower sand may be oil productive. We have reviewed the information available ón the South Barrow #12 and are unable to understand why the lower sand (sag river?) did not yield more oil. We really do not know how the test was attempted and suspect that it is a mechanical failure. I have taken a small sample of the oil from the well and placed it in the refrigerator where it did not congeal at temperatures of around 40 degrees. Judging from' the core analyses, it would seem that the reservoir should have given up more fluid than it did. This well is recommended subject to budget limita- tions, repair of the Carwell rig and succe~sful completion of Barrow #13. J\.]D : Ij b ~ h ¡ f' . " jl L.'lJ ..-, v j , j i cc: I1r.

Navy South Barrow Well No. 14 is located in the East Barrow Gas Field in the National Petroleum Reserve in Alaska, formerly Naval Petroleum Reserve No. 4 (Figure 1). The designation "East Barrow Gas Field" is now applied to those wells which were earlier identified as "South Barrow Gas Field, East Area". The South Barrow Gas Field and the East Barrow Gas Field are now recognized as two separate fields. The well is located 2300' from the west line and 1800' from the north line of protracted Section 25, Township 22 North, Range 17 West, Umiat Meridian (Latitude: 71°13'58.79" North; Longitude: 156°18'11.02" West). The Alaska State Plane Coordinates are X = 699,955 and Y = 6,303,590, Zone 6. Elevations are 12' ground level, 17' drilling pad and 31' Kelly bushing. Drilling related operations started November 20, 1976, with mobilization of construction crews and equipment for the building of the drilling location. Rig-up operations began January 18, 1977, with the rig being moved from the South Barrow No. 13 location. Operations at South Barrow No. 14 ended on March 10, 1977. The well was drilled to a total depth of 2,257 feet. The primary objectives of the well were the Barrow Gas sand and the Sag River Sandstone. At the conclusion of the drilling and evaluation operations, the well was killed with calcium-chloride water and a retrievable bridge plug set above the productive interval. The well was suspended as a productive natural gas well. A kill string was installed in the hole when the well was suspended. Husky Oil NPR Operations, Inc. supervised and directed the drilling and completion operations as prime contractor for the Navy. Parco, I nc. was the labor contractor. The rig used was the Navy's Cardwell Model H. ~ SOUTH BARROW WELL No.14 ...rmow.«;¿ _ e 1:"4 {/ 7hÞ' C"MP ,coo/¡>,. sf" _ lON~lY Sl:"4 II' c II ~,"'" /, . . , )/ , , i-,........._-;"_ i ",I'~~ '."\.. .1 eOfJ~:t..r\ I "'J-- '-.~ oJ (j \ \ J ".."ú".......

DRILLING SUMMARY Field operations at the South Barrow No. 14 location were started on November 20, 1976, with the mobilization of construction crews and equipment required to build the drilling pad. The rig move from South Barrow No. 13 began on January 18, 1977, and actual placement of components and rig-up began the same day. Rig-up was completed in 10 days and the well spudded at 1:30 a.m., January 28,1977. Rig move operations were delayed somewhat due to the unavailability of equipment and condition of the support equipment used in the rig move. Some time was also lost during the drilling of the conductor hole. The locking pin which connected the drive sub to the auger dropped out resulting in a fishing job to retrieve the auger. The conductor hole was drilled to 53' KB, and 20" conductor was set and cemented to surface with 53 sacks of Permafrost cement. A 16" annular blowout preventer and diverter lines were installed on the 20" conductor. A 13-1/2" hole was drilled from 53' to 1048'. Two 13-1/2" stabilizers were run in the drill string to limit deviation. The hole was logged from 1048' to the bottom of the 20" conductor with a 01 L/SP and a BHC-Sonic/GR. After logging, 10-3/4" surface casing was run and landed at 1042'. The casing was cemented to surface with 760 sacks of Permafrost cement. A 10" 3,000 psi blowout-preventer stack was installed on the 10-3/4" casing. Choke manifold and kill lines were also installed. The casing, blowout preventer, choke and kill lines were tested to 1,250 psi. The casing was drilled out with an 8-1/2" bit and the formation was tested to a 0.68 psi/ft. equivalent gradient. An 8-1/2" hole was drilled to 1950'. The well was logged from 1950' back into the 10-3/4" shoe at 1042' as follows: 01 L/SP; BHC-Sonic/GR; FOC/CNL/CAL/GR; and HOT-Oipmeter. The sidewall-core gun initially would not go below 1050'. The hole was conditioned and deepened to 1955'. The sidewall-core gun was again run, ten cores were shot and ten were recovered. A 7" intermediate production casing string was run to 1947' and cemented to surface with 760 sacks Permafrost cement, tailed in with 125 sacks Class "G" cement. The float collar and shoe joint were drilled out leaving five feet of cement above the shoe. A CBL/VOL/CCL/GR log was run and it indicated an acceptable cement job behind the casing. I n order to minimize possible formation damage, a calcium chloride-ligno-sulfonate mud system was mixed. To accomplish the mixing and conversion to the inhibitive mud, the mud mixing system had to be rebuilt and modified. The mud guns, jets, and mud line to the hopper were modified, requiring approximately one day to change over the mud. The tubing head and blowout preventer had been nippled up prior to cleaning out the 7" casing. The casing and blowout preventer were tested to 1,250 psi. The shoe was drilled out with a 6" bit. The formation was tested to a 0.78 psi/ft. equivalent gradient. 2 . . I I I I I I I I I I I I I I I I I I I A 6" hole was drilled from 1955' to 2257'. Drill Stem Test No. 1 was conducted on the way down over the interval 1947' to 2100', with a packer set in the 7" casing at 1890'. A 500 psi nitrogen cushion was used and bled off when the tool was opened to eliminate a sudden pressure differential on the formation. I n summary, the well flowed gas at an approximate rate of 2.5 MMCFPD during the final flow period of the test. A lost-circulation/gas-kick situation developed at 2257' while attempting to cut a core. The core barrel packed off while trying to break circulation on bottom and 60 barrels of mud were lost. The core barrel was pulled into the 7" shoe at 1947' and, while building mud weight and volume, the well kicked. Approximately 69 hours rig time were used to bring the well under control and a total of 550 barrels of mud were lost. The well was controlled with a 10.7 ppg mud containing 30% lost-circulation material. After controlling the well, an open-hole plug of 25 sacks of Class "G" cement (with 2% calcium-chloride accelerator) was spotted at 2257'. The top of the plug was tagged at 2114' and polished off to 2128'. The open hole was logged from 2128' back into the casing shoe at 1947' as follows: DIL/SP; BHC-Sonic/GR; FDC/CNL/CAL/GR; DLL/SP; MLL; HDT- Dipmeter. Shot 11 sidewall cores and recovered 11. At the conclusion of logging, the top of the plug was found at 2191', 63' deeper than its origi nal depth. A second pi ug of 15 sacks of accelerated Class "G" cement was spotted at 2191' and the top dressed to 2130'. The lost-circulation material was cleaned from the mud system. The hole was conditioned and a 5-1/2" slotted liner was run. On the first attempt, it would not go below 700'. After pulling it and repairing the Brown Oil Tools liner hanger and packer assembly, the liner was rerun and hung with the shoe at 2125'. The hanger was at 1826' and the packer at 1822'. The blowout preventers were tested to 1,400 psi and 2-7/8" tubing run to 2079' (tail 12' below lowest slots in 5-1/2" liner). The tree was nippled up and tested to 3,000 psi. Preparations were made to conduct a multi-point back-pressure test on the well. The mud was reversed to calcium-chloride water in an attempt to flow the well. This failed, the calcium-chloride water was displaced with nitrogen to 600 psi, and the nitrogen bled off to bring the well in. The well was cleaned up by alternating the gas flow through the tubing and the annulus. Alcohol was injected into the tubing and annulus to prevent hydrate formation. The multi-point test was run and a 72-hour pressure buildup taken with bottom-hole recorders hung at 2073' on a wire line. At the conclusion of buildup, a static gradient su rvey was conducted. Calculated absolute open flow was 3.7 MMCFGPD. The test is detailed in Appendix I. Also, an analysis of gas recovered is in Appendix II. After testing, the well was completed. The well was killed with 10.8 ppg calcium-chloride water and blowout preventers were nippled up and tested to 1,250 psi. The tubing was pulled, a retrievable bridge plug was run on the tubing, and was set at 1772'. One joint of tubing was laid down 3 I I I I I I I I I I I I I I I I I I I . . and the tubing string was hung at 1754', with the bridge plug running tool on the bottom. The tree was nippled up and tested to 3,000 psi. The rig was released at 7:00 a.m., March 1,1977. A wellhead shelter was constructed and placed over the wellhead. All logs from the South Barrow Gas Field were recorded on magnetic tape, and computer log interpretation presentations were prepared using Schlumberger's Saraband synergetic log system. The hole was, for all practical purposes, "straight". The maximum deviation of 1-3/4° occurred at 2182' in the 6" hole. The remainder of the hole was drilled at 1° or less deviation. Detailed drilling information, in the form of bit records, mud summary, time analysis, and casing and cementing reports, is included in the body of this report. 4 I . .

CASING INTRODUCTION Casing programmed for South Barrow Well No. 14 was as follows: 20" conductor at ±80'; 10-3/4" at ±1200'; 7" at ±2500'; and a 2-7/8" production string if the well was to be completed. Actual casing run was 20" at 53', 10-3/4" at 1042', 7" at 1947'. A 5-1/2" slotted liner was run from 1822' to 2125', and a 2-7/8" string of production tubing hung at 1754' to complete the well. The 2-7/8" tubing had originally been run to 2079' for testing of the well, then was pulled, a retrievable bridge plug set at 1772', and the 2-7/8" tubing re-hung at 1754'. 33 I . I I .

I I I March 18, 1977 I MEMORANDUM TO FILE - SOUTH BARROW WELL NO. 14 SUBJECT: Pressure Buildup Survey and Open Flow Potential Analysis I 1. Pressure Buildup Analysis A. SUllllllary of Results: I 1. Initial reservoir pressure is extrapolated to be 963 psia. 2. The kh product has been calculated to be 346.28 md. ft. I 3. Assuming a productive thickness of the main producing sand is 22' from the logs. the calculated average permeability to gas is 15.74 md. 4. The average calculated mobility of gas is 1356.90 md./cp. I 5. The skin effect calculated 1 hour after shut in is -1.78. The corresponding pressure difference is -23 psi. I 6. The effective wellbore radius is calculated to be 1.48 ft. 7. The actual reservoir productivity index is calculated to be 17.32 MCFD/psi. I 8. The order of magnitude radius of investigation for the transient pressure buildup is calculated to be 270 ft. B. Discussion: I The bottomhole pressure buildup survey on the South Barrow Well No. 14 was conducted as a 72 hour shut in commenced after a stable flow period of 10 hours, following and as a part of the Open Flow Potential Test conducted on the well. The pressure data was recorded on Amerada pressure gauges run on wireline and hung in the well opposite the main producing sand. The raw data is presented in Camco report for the subject well and test. Further analysis of the data was necessary to define the pressure buildup response. The data analysis procedure is outlined below. I I I The data were replotted in the conventional gas analysis manner and are attached as figures I, 2, and 3. Critical properties of the gas were calculated from the gas compositional analysis of samples from DST No.1. analyzed by Chemical and Geological Laboratores of Alaska. Inc. Since the production history of the well prior to shut in had consisted of several flow rates. the multiple rate history was incorporated into the analysis. Figure 4 depicts the rate. time history of the well. I I I I I-I c. . . I I I Results: I 1. The initial reservoir pressure of 963 psia was derived from the extrapolation of the curve of figure 3. The value agrees with the final measured values obtained during the final 26 hours of the pressure buildup. I 2. From analysis of the slope of the straight line portion of the buildup, the kh product was calculated to be 346.28 md. ft. Average reservoir flowing temperature and pressure were used to calculate the average physical properties of the gas. I 3. I The calculation of average permeability requires the assumption of a productive thickness and the require- ment that the total production come from this thickness. Log analysis indicates the thickness of the main productive sand to be 22 ft. As a result, the calculated average permeability to gas is 15.74 md. I 4. The average mobility to gas is calculated to be 1356.90 md./cp. at average reservoir flowing temperature and pressure. I 5. The calculated skin effect is -1. 78, and the corresponding pressure difference is -23 psi. Since the well had been recently drilled and not subject to stimulation treatment, it is unlikely that a negative skin should be evidenced at this time. However, the determination of the sldn is a function of the flow rate and pressure distribution around the wellbore. As such, it is sensitive to the completion scheme employed. Since the well is completed with a slotted liner type completion, other intervals are open to pro- duction besides the main sand. This being the case, the assumption that the entire production is attributable to the main sand may be slightly in error. Minor production may be derived from other zones, resulting in an abnormally low skin calculated in the main sand. Qualitative inspection of the buildup curve indicates that some small layering effect, probably in the absence of cross flow , is present with a reservoir pressure nearly the same as the main sand. I I I I 6. As a result of the above, and assuming for practical pur- poses that the entire production is attributable to the main sand, the effective wellbore radius is calculated to be 1.48 ft. I 7. The reservoir productivity index is calculated to be 17.32 MCFD/psi. I 8. Using the van Poolen equation as an order of magnitude estimate, the radius of investigation for the transient I I I 1-2 I I . . I I I pressure buildup is calculated to be 270 ft. It must be remembered that this is an estimate only. II. Open Flow Potential Analysis I A. Summary of Results: I 1. The Absolute Open Flow Potential of the Well is 3,700 MCF/D. 2. The exponent (n) of the back-pressure curve is 0.56. 3. The angle of the slope of the back-pressure equation is 60.950. I B. Discussion: The Open Flow Potential Test was conducted as a multi-point stabilized back pressure test. I Minor problems were encountered with hydrate formation but were overcome without incident by lubricating alcohol and blowing down as required. I Flow measurements were taken by means of a 21n. critical flow prover. Bottomhole flowing pressures were calculated from flowing surface pressures by means of the Smith Equation, at average values of pressure, temperature and physical properties. Reservoir pressure was determined from the pressure buildup analysis discussed previously. I I The data were plotted and analyzed using the conventional multi- point back-pressure analysis and plot and is attached as figure 5. C. Results: 1. Data used in plotting back-pressure curve.

Conclusions The testing equipment and procedures were adequate to effectively determine the basic reservoir properties and to determine the Open Flow Potential of the well. Should more rigorous determinations be necessary, the test equipment should be upgraded and testing pro- cedures carefully planned and executed to derive the maximum useful ~;¿¡:u~ j M.

I . . I INTRODUCTION I The South Barrow No. 14 Well is located east southeast of the South Barrow Gas Field and southeast of Barrow, Alaska, on Naval Petroleum Reserve No.4. The well is situated 2300' from the west line and 1800' from the north line of Section 25, Township 22 North, Range 17 West, Umiat Meridian. Drilling related operations commenced November 20, 1976, with mobilization of construction crews and equipment for the building of the drilling location. Rig up operations commenced January 18, 1977, with the rig being moved from the South Barrow No. 13 location. Ope- rations at South Barrow No. 14 ended on March 10, 1977, with the final movement of rig components to storage areas at NARL and pads in the South Barrow Gas Field. I I' I The well was drilled to a total depth of 2257'. The primary objectives of the well were the Basal Jurassic Gas Sand and the Sag River Sand- stone above the Argillite basement rock. At the conclusion of the drilling and evaluation operations, the well was killed with calcium chloride water and a retrievable bridge plug set above the productive interval. The well was suspended with a kill string in the hole. I I Husky Oil NPR Operations, Inc., supervised and directed the drilling and completion operations as prime contractor for the Navy. Parco, Inc., was the labor contractor. The rig used was the Navy Cardwell Rig, a Cardwell Model H, owned by the Navy. I I I I I I- I I I I I i I . . I DISCUSSION I Field operations at the South Barrow No. 14 location commenced on November 20, 1976, with the mobilization of construction crews and equipment required to build the drilling pad. The rig move from South Barrow No. 13 began on January 18, 1977, and actual placement of com- ponents and rig up began the same day. Rig up was completed in 10 days and the well spudded at 1:30 a.m., January 28, 1977. I I Rig move operations were delayed somewhat due to the unavailability and condition of the support equipment used in the rig move. Some time was also lost during the drilling of the conductor hole. The locking pin which connected the drive sub to the auger dropped out resulting in a fishing job to retrieve the auger. The conductor hole was drilled to 53' KB and 20" conductor set and cemented to surface with 53 sacks of Permafrost cement. I I I A 16" annular BOP and diverter lines were installed on the 20" conductor. A 13~" hole was drilled from 53' to 1048'. Two 13~" stabilizers were run in the drill string to limit deviation. The hole was logged from 1048' to the bottom of the 20" conductor with a Dual Induction Laterolog and the BHC Sonic/Gamma Ray log. After logging, 10 3/4" surface casing was run and landed at 1042'. The casing was cemented to surface with 760 sacks of Permafrost cement. I A 10" 3000 psi BOP stack was installed on the 10 3/4" casing. Choke manifold and kill lines were also installed. The casing, BOP, choke and kill lines were tested to 1250 psi. The casing was drilled out with an 8~" bit and the formation tested to a 0.68 psi/ft equivalent gradient. An 8~" hole was logged from 1950' to 1042' with a Dual Induction Latero- log, BHC Sonic/Gamma Ray log, Compensated Formation Density/Compensated Neutron/Gamma Ray log and the High Resolution Dipmeter. Sidewall core guns initially would not go below 1050'. The hole was conditioned and deepened to 1955'. Sidewall core guns were again run. Ten cores were attempted at selected intervals with 100% recovery. A 7" intermediate/ production casing string was run to 1947' and cemented to surface with 760 sacks Permafrost cement, tailed in with 125 sacks Class "G" cement. The float collar and shoe joint were drilled out leaving five feet of cement above the shoe. A Cement Bond/Variable Density/Gamma Ray/Casing Collar Locator log was run to determine the quality of the cement job. I I I 1- I I In order to minimize possible formation damage, a calcium chloride-ligno- sulfonate mud system was mixed. To accomplish the mixing and conversion to the inhibitive mud, the mud mixing system had to be rebuilt and modifed. The mud guns, jets, and mud line to the hopper were modified, requiring approximately one day to change over the mud. I The tubing head and BOP had been nippled up prior to cleaning out the 7" casing. The casing and BOP were tested to 1250 psi. The shoe was drilled out with a 6" bit. The formation was tested to a 0.78 psi/ft equivalent gradient. A 6" hole was drilled from 1955' to 2100'. DST No.1 was run with the packer set in casing at 1890'. The drill pipe I I I ii I . . I was loaded with a 500 psi nitrogen gas blanket to prevent hole sloughing due to the sudden differential imposed as the tool opened. The well flowed gas at an approximate rate of 2.4 MMCFD during the final flow period. Drilling was resumed to 2257'. The core barrel was picked up and run in the hole. While attempting to break circulation, the core barrel packed off and 60 barrels of mud were lost. After pulling to the shoe of the 7" casing and while building mud volume, the well kicked. BOPs were closed and attempts were made to circulate the gas bubbles out. Three lost-circulation material pills were spotted on the bottom with no returns. Total mud loss to this point was 140 barrels. Attempts were made to fill the annulus and regain circulation with no success, losing another 210 barrels of mud, totaling 450 barrels lost. Circu- lation was finally regained with 10.7 ppg mud with 30% lost circulation material. The total mud loss amounted to 550 barrels. I I I I Approximately 69 hours rig time was lost in controlling the lost circu- lation and the kick. Two hours were lost repairing the C-250 mud pump. Much of the time lost was due to the lack of surface mud volume and the poor condition of the mud mixing equipment. I 1 After stabilizing the hole, the core barrel was laid down. A retrievable bridge plug was set and the BOP tested to 300 psi and 1200 psi. The bridge plug was retrieved and a 6" bit was staged in the hole to con- dition the mud and stabilize the system. Gas cut mud was also circulated from the well. The drill pipe was tripped in open ended and an open hole plug was spotted at 2257', using 25 sacks of Class "G" cement containing 2% calcium chloride as an accelerator. The top of the cement plug was tagged at 2114' and polished to 2128'. The hole was logged with the Dual Induction Laterolog, BHC Sonic/Gamma Ray log, Compensated Formation Density/Compensated Neutron/Gamma Ray log, Dual Laterolog/SP log, and the High Resolution Dipmeter. Eleven sidewall cores were shot and recovered. On each successive logging run, the top of the cement plug had been tagged deeper than the previous run. A 6" bit was run and the cement plug tagged at 2191', 63' deeper than the original depth. A second plug was spotted at 2191' with 15 sacks of Class "G" containing 2% calcium chloride as accelerator. The plug was dressed to 2130'. The lost circu- lation material was shaken out of the mud system and the open hole con- ditioned for running a liner. A 5~" slotted liner was run but would not go below 700'. The liner was pulled and repairs made on the Brown Oil Tools liner hanger and packer assembly. The liner was rerun and hung with the shoe at 2125', the hanger at 1826', and the packer at 1822'. I I I I 1- I I The BOPs were tested to 1400 psi and 2 7/8" tubing was run and landed at 2079', with the tail 12' below the lowest slots in the liner. The tree was nippled up and tested to 3000 psi. The well was reverse circulated to 9.0 ppg calcium chloride water but did not flow. I The calcium chloride water was displaced from the well with nitrogen through the tubing with returns from the annulus. After releasing the nitrogen, the well flowed through the annulus. The well was cleaned up, alternating flow from the tubing and the annulus. Alcohol was lubricated into the tubing and annulus to prevent hydrate formation. A 1 1 I iii I . . I multi-point back-pressure test was conducted on the well; and at the conclusion, a 72-hour pressure buildup was conducted with bottom hole pressure recorders hung on wire line at 2073'. At the conclusion of the buildup, a static gradient survey was conducted. The well was killed with calcium chloride water. I I BOPs were nippled up and tested to 1250 psi. The tubing was pulled and a retrievable bridge plug run on tubing and set at 1772'. One joint of tubing was laid down and the tubing string hung at 1754', with the bridge plug running tool on the bottom. The tree was nippled up and tested to 3000 psi. The rig was released at 7:00 a.m., March 3, 1977. I I The rig was rigged down and moved to storage areas at NARL and various pads in the South Barrow Gas Field. The location was cleaned and leveled after the rig components had been removed. A wellhead shelter was con- structed and placed over the wellhead. I All logs from the South Barrow Gas Field were recorded on magnetic tape, and computer log interpretation presentations were prepared using Schlumberger's Saraband synergetic log system. The hole was, for all practical purposes, "straight." The maximum deviation of 1 3/40 occurred at 2182' in the 6" hole. The remainder of the hole was drilled at 10 or less deviation.

I March 18, 1977 I MEMORANDUM TO FILE - SOUTH BARROW WELL NO. 14 SUBJECT: Pressure Buildup Survey and Open Flow Potential Analysis I 1. Pressure Buildup Analysis I A. Summary of Results: 1. Initial reservoir pressure is extrapolated to be 963 psia. I 2. The kh product has been calculated to be 346.28 md. ft. I 3. Assuming a productive thickness of the main producing sand is 22' from the logs, the calculated average permeability to gas is 15.74 md. I 4. The average calculated mobility of gas is 1356.90 md./cp. I 5. The skin effect calculated 1 hour after shut in is -1.78. The corresponding pressure difference is -23 psi. 6. The effective wellbore radius is calculated to be 1.48 ft. I 7. The actual reservoir productivity index is calculated to be 17.32 MCFD/psi. I 8. The order of magnitude radius of investigation for the transient pressure buildup is calculated to be 270 ft. B. Discussion: I I The bottomhole pressure buildup survey on the South Barrow Well No. 14 was conducted as a 72 hour shut in commenced after a stable flow period of 10 hours, following and as a part of the Open Flow Potential Test conducted on the well. The pressure data was recorded on Amerada pressure gauges run on wireline and hung in the well opposite the main producing sand. The raw data is presented in Camco report for the subject well and test. Further analysis of the data was necessary to define the pressure buildup response. The data analysis procedure is outlined below. I I I The data were replotted in the conventional gas analysis manner and are attached as figures 1, 2, and 3. Critical properties of the gas were calculated from the gas compositional analysis of samples from DST No.1, analyzed by Chemical and Geological Laboratores of Alaska, Inc. Since the production history of the well prior to shut in had consisted of several flow rates, the multiple rate history was incorporated into the analysis. Figure 4 depicts the rate, time history of the well. I I I 39 I I I I I· I 1 I I I 1 I I I' I 1 I 1 I C. . . Results: 1. The initial reservoir pressure of 963 psia was derived from the extrapolation of the curve of figure 3. The value agrees with the final measured values obtained during the final 26 hours of the pressure buildup. 2. From analysis of the slope of the straight line portion of the buildup, the kh product was calculated to be 346.28 md. ft. Average reservoir flowing temperature and pressure were used to calculate the average physical properties of the gas. 3. The calculation of average permeability requires the assumption of a productive thickness and the require- ment that the total production come from this thickness. Log analysis indicates the thickness of the main productive sand to be 22 ft. As a result, the calculated average permeability to gas is 15.74 rod. 4. The average mobility to gas is calculated to be 1356.90 md./cp. at average reservoir flowing temperature and pressure. 5. The calculated skin effect is -1.78, and the corresponding pressure difference is -23 psi. Since the well had been recently drilled and not subject to stimulation treatment, it is unlikely that a negative skin should be evidenced at this time. However, the determination of the sltin is a function of the flow rate and pressure distribution around the wellbore. As such, it is sensitive to the completion scheme employed. Since the well is completed with a slotted liner type completion, other intervals are open to pro- duction besides the main sand. This being the case, the assumption that the entire production is attributable to the main sand may be slightly in error. Minor production may be derived from other zones, resulting in an abnormally low skin calculated in the main sand. Qualitative inspection of the buildup curve indicates that some small layering effect, probably in the absence of cross flow, is present with a reservoir pressure nearly the same as the main sand. 6. As a result of the above, and assuming for practical pur- poses that the entire production is attributable to the main sand, the effective wellbore radius is calculated to be 1.48 ft. 7. The reservoir productivity index is calculated to be 17.32 MCFD/psi. 8. Using the van Poolen equation as an order of magnitude estimate, the radius of investigation for the transient -2- 40 1 1 II. 1 1 I- 1 1 1 1 1 I I I 1 1 I I 1 1 . . pressure buildup is calculated to be 270 ft. It must be remembered that this is an estimate only. Open Flow Potential Analysis A. Summary of Results: 1. The Absolute Open Flow Potential of the Well is 3,700 MCF/D. 2. The exponent (n) of the back-pressure curve is 0.56. 3. The angle of the slope of the back-pressure equation is 60.950. B. Discussion: The Open Flow Potential Test was conducted as a multi-point stabilized back pressure test. Minor problems were encountered with hydrate formation but were overcome without incident by lubricating alcohol and blowing down as required. Flow measurements were taken by means of a 21n.critical flow prover. Bottomhole flowing pressures were calculated from flowing surface pressures by means of the Smith Equation, at average values of pressure, temperature and physical properties. Reservoir pressure was determined from the pressure buildup analysis discussed previously. The data were plotted and analyzed using the conventional multi- point back-pressure analysis and plot and is attached as figure 5. C. Results: 1. Data used in plotting back-pressure curve.

Conclusions I The testing equipment and procedures were adequate to effectively determine the basic reservoir properties and to determine the Open Flow Potential of the well. Should more rigorous determinations be necessary, the test equipment should be upgraded and testing pro- cedures carefully planned and executed to derive the maximum useful ;1/#4 J M.

GEOLOGIC SUMMARY INTRODUCTION The U. S. Navy, South Barrow Well No. 14 is located in the NW 1/4 of protracted Section 25, T22N, R 17W, Umiat Meridian, North Slope Borough, Alaska. The surveyor's plat locates the well 2300' FWL and 1800' FNL of the section (see Figures 1 & 2). The well was drilled in early 1977 by the U. S. Navy to provide additional gas reserves for the village of Barrow, and secondarily, to investigate at this location oil shows which had been encountered in the Sag River Sandstone in the South Barrow Well No. 12. Drilling operations commenced on January 28, 1977. The well was completed as a suspended gas producer in the Lower Barrow sand on March 1, 1977. Good visual sample shows were encountered in several sandstones of the lower part of the "Pebble Shale", in the Lower Barrow sand of the Kingak Formation; and in the Sag River Sandstone. One drill-stem test was conducted in the Lower Barrow sand from 1947-2100' (see Appendix C). No conventional cores were taken although 21 sidewall cores were shot and recovered. In each of the South Barrow wells drilled after South Barrow No. 13, an inhibitive mud system, containing calcium chloride, was used below the intermediate casing (9-5/8" to approximately 1,500 feet, except for 7" in South Barrow No. 14 at 1,947 feet). This was done in order to minimize damage by the swelling of clays, which were known to exist in the Barrow sandstones and the Sag River Sandstone (determined by water susceptibility tests on cores from the South Barrow Nos. 12 and 13 wells). PRE-DRI LUNG PROGNOSIS The South Barrow No. 14 well was drilled with a primary objective of further evaluating the discovery of gas production in the Lower Barrow sandstone established in South Barrow Well No. 12 in March and April of 1974. The secondary objective was to core and test the oil shows which had been found in the Sag River Sandstone of South Barrow Well No. 12. This well was reported to have swabbed an unspecified amount of oil from the Sag River Sandstone before being swabbed dry. Another objective in drilling South Barrow No. 14, was to drill the well using a calcium chloride based mud system in order to minimize formation damage from swelling clays. The presence of swelling clays in potential reservoi r sa ndstones in South Ba rrow No. 12 had been confi rmed by water-susceptibility tests, which were performed on core chips from the Lower Barrow sand, and from the Sag River Sandstone. Damage from fresh-water mud was suspected as being responsible for the poor performance of the Lower Barrow sand in South Barrow No. 12 (360 MCFPD). Core analysis and log calculations had indicated that the sandstone should have been capable of higher flow rates. 1 . . I I I I I I I ,I I I I I I I I I I I I POST-DRILLING SUMMARY The primary objective of the well was satisfactorily met, since the Lower Barrow sandstone tested gas at a rate of 2.5 MMCFPD, substantiating the use of the calcium chloride mud system and providing additional gas reserves in the Barrow area. The secondary objective in drilling the South Barrow No. 14 well was not fulfilled, since lost circulation at 2,257 feet, while preparing to core (the lost circulation presumably occurred in the Sag River Sandstone, which had been topped at 2,240 feet, according to the drilling time), forced the aborting of further drilling, coring, or testing in the Sag River Sandstone. Furthermore, no electric log was obtained through the section, since a cement plug had to be set, sealing off the Sag River Sandstone. 2 --~-~-------------- "T .......

LEGG INTRODUCTION The South Barrow Well No. 14 was drilled in early 1977 by Husky Oil NPR Operations, I nc. under contract to the U. S. Navy. This was one of two Barrow wells (the other was the South Barrow No. 13 well) to be drilled in the final drilling effort of the U. S. Navy before relinquishing the Naval Petroleum Reserve No. 4 to the administration of the Department of the Interior. The objective, in drilling the South Barrow No. 14 well, was to complete the well as a gas producer in the Lower Barrow sandstone for eventual delivery of gas to the village of Barrow. The secondary objective of the well was to evaluate the Sag River Sandstone to ascertain its potential as a possible productive reservoir. An unspecified amount of oil had reportedly been swabbed from the Sag River Sandstone in South Barrow No. 12 well. Apparently, no serious attempt to complete the well in the Sag River Sandstone had been made at that time, partly because of suspected formation damage from swelling clays. Drilling was commenced on January 28, 1977, and the well was drilled to 2,257 feet (driller), losing circulation at that depth while attempting to core in the Sag River Sandstone. The well was completed as a suspended gas producer in the Lower Barrow Gas sand after lost-circulation problems made it necessary to cement-off the Sag River Sandstone, and plug-back for the gas completion. The well was completed, suspended, and the rig was released on March 1, 1977.

I I I I I I I I I I I I I PLEISTOCENE Pleistocene: 53-80' Lithologies in this interval are primarily sands, containing some carbonaceous fragments and several mollusk shell fragments. The sands are light gray to dark gray, fine to coarse grained and quartzose. I nterbedded with the sands are beds of clay. The clay is gray, sandy, silty, pyritic, and carbonaceous. Shell fragments are present in the clays. Sediments of the Pleistocene are present in the South Barrow No. 14 well from the base of the conductor pipe (53') down to a depth of 80 feet, according to the micropaleontological analysis by Anderson, Warren & Associates, Inc. CRETACEOUS Torok Formation: 80-1364' The Torok Formation is composed, for the most part, of claystones down to approximately 485 feet, where several thin, interbedded sandstones are present. The claystones are gray, gray-brown, and brown, and are typically sandy, silty, frequently contain chert pebbles, and are usually carbonaceous; occasional to rare, thin beds of coal are also present. From approximately 485 to 530 feet is sandstone, which is brown, very fine grained, very argillaceous and silty, typically grading to claystones and shaly siltstones. The sandstones are also micaceous and carbonaceous. No show was observed. Between depths of 530 and 710 feet, the Torok is principally claystone. A thin sandstone, associated with thin coal beds and stringers, is present from 710 to 720 feet. The sandstone is gray to brown, very fine to fine grained, and devoid of any shows. Below 720 feet, the claystones of the Torok become more lithified and alternate with, and grade into, dark gray to black shales. The shales contain frequent pyrite inclusions and are generally silty, grading into and interbedded with very argillaceous siltstones. The lower part of the Torok (1230-1310') includes several thin beds of sandstone.' These sandstones are light gray, very fine grained, carbonaceous and micaceous. The sandstones are argillaceous and silty, and grade to siltstone and shale. No shows were observed in the sandstones. 7 I I I I I I Anderson, Warren & Associates, Inc. picks the top of the Aptian-Albian age, Torok Formation, at 80 feet. The base of the interval is picked at 1,370 feet, which is in very close agreement with the electric-log pick at 1,364 feet. H Pebble Shale": 1364-1723' From 1 ,364 feet, down to a depth of approximately 1,520 feet, the "Pebble Shale" is primarily a dark gray to black shale, grading from flaky to I I I I I I I I I I I I I I I I I I I . . finely fissile, and containing rounded, "floating", frosted quartz grains, which are characteristic of this unit. At 1,520 feet, and persisting down to the base of the "Pebble Shale" at 1,723 feet, is an interbedded sequence of sandstones, siltstones, and shales. The sandstones are gray and brown-gray, very fine to fine grained, silty, argillaceous, and carbonaceous. There is oil staining in the sandstones, ranging from light stain to good overall staining. These s,hows yielded cuts ranging from very weak to very good. Electric logs reveal these sandstones to be very thin, totaling only 23', for the three best developed sandstones which exhibit high resistivity (interpreted as oil or gas). . There is a distinctive gamma-ray increase at a depth of 1,364 feet; this gamma-ray response defines the top of the "Pebble Shale". Anderson, Warren & Associates, Inc. picks the Early Cretaceous, Neocomian age, as beginning at a depth of 1,370 feet, which is in close agreement with the electric-log pick. JURASSIC Kingak Formation: 1723-2130' The Upper Barrow sand has "shaled out" in South Barrow Well No. 14. Producible gas is present in the Lower Barrow sandstone, as evidenced by the drilling of South Barrow Well No. 12 and confirmed in South Barrow Well No. 14. The Kingak Formation, starting at 1,723 feet, is composed of shale, which is dark gray and brown-gray, slightly fissile, silty, frequently sandy, and often contains siderite nodules and chert pebbles. A predominant shale lithology persists down to a depth of approximately 1,910 feet, where the Kingak becomes slightly sandy (correlating to the Upper Barrow sandstone interval), An interbedded sequence of shaly, silty sandstones, siltstones and shales, then persist all the way to the base of the Kingak at 2, 130 feet. The shales are similar to those in the upper part of the Kingak with the sandstones being generally very thin (the exception being the Lower Barrow sandstone, which will be discussed separately), both silty and shaly, and very fine to fine grained. The siltstones are usually gray to brown, very sandy, grading to sandstone, and contain numerous claystone and shale stringers. This enti re sequence of sandstones, siltstones and shales, appears to be completely gradational, each grading into the other. Economically, rocks within the Kingak Formation are the most important sequence in the sedimentary section in the South Barrow wells. Gas productive sandstones in the Kingak, specifically, the Upper and Lower Barrow sands, are the units that provide the gas which is so necessary to the village of Barrow. The top of the Kingak Formation is picked on the basis of electric-log correlations where the datum of 1,723 feet agrees fairly closely with the micropaleontological pick at 1,750 feet. The base of the Kingak, according to micropaleontology, is at 2, 130 feet. There is general agreement with the electric logs. 8 . . I I I I I I I I I I I I I I I I I I I Lower Barrow sandstone: 2057-2083' The Lower Barrow sandstone is represented on the Dual Induction Laterolog by a positive spontaneous-potential (S. P.) development and by a modest resistivity increase, which would not, at first glance, appear to indicate hydrocarbons. The positive S. P. development is caused by the low resistivity of the calcium-chloride drilling mud. The resistivity of the mud is lower than the resistivity of the connate water in the sandstone, hence a positive S. P. deflection. The rather low resistivity in the sandstone is probably a function of invasion by the saline mud filtrate, augmented by the shaliness of the sandstone matrix. Lithologically, the sandstone is light tan, very fine to fine grained, silty, and clayey; it exhibited poor to fair scattered staining, with a fair cut. Log porosities are 24-30%, which is high and is probably optimistically affected by formation gas content and the shaly matrix. The actual porosity is probably around 20%. TRIASSIC Triassic: 2130-2257' The Triassic section, down to the Sag River Sandstone at 2,240 feet, is represented by shales and siltstones. The shales are typically gray, soft, silty to sandy, with sandstone laminae, and with frequent siderite nodules. The siltstones are gray, shaly and sandy, hard, and contain numerous chert fragments. Anderson, Warren & Associates, Inc. have assigned a Triassic age to the sedimentary section below 2,130 feet and continuing down to the total depth of 2,257 feet. Within the Triassic section is the Sag River Sandstone (encountered at 2,240 feet by samples and drilling time). Sag River Sandstone: 2240-2257' (Total Depth) On the bases of drilling time and sample lithology, the Sag River Sandstone was encountered at 2,240 feet. The sandstone is gray, very fine to fine grained, occasional medium grained, rounded, frosted to clear quartz. Good oil staining was reported from the wellsite. There were some traces of a brown, sideritic sandstone, which is very fine to fine grained, shaly and silty,· and with a few inclusions of glauconite. Unfortunately, there were no samples from 2250-2257', because the well lost circulation at 2257'. There are also no electric logs below 2128', because the well was plugged back in order to cu re the lost-ci rculation problem. HYDROCARBON SHOWS AND DRI LL-STEM TESTS As mentioned under the various stratigraphic descriptions, there were several zones of show noted in the South Barrow No. 14 well. Fair to good apparent oil shows were noted in several thin somewhat shaly sandstones in the lower part of the "Pebble Shale". From an examination of the electric logs, in conjunction with observed sample shows, the following zones could merit further evaluation in either this well or some futu re offset well: 9 I I I I I I I I I I I I I I I I I I I . . (1) Sandstone: 1576-1582' (6' net); 21% density porosity; 31% neutron porosity; neutron has "gas effect" and shaliness effect; probable hydrocarbons, likely gas. (2) Sandstone: 1612-1621' (9' net); 27% density porosity; 33% neutron porosity; obvious "gas effect" with neutron and density "cross-over"; definite gas. (3) Sandstone: 1646-1654' (8'); 30% density porosity; 37% neutron porosity; good gas separation between neutron and density curves; obvious gas. The Lower Barrow sand has porosities of 24-30% on the density and 33-37% on the neutron log. The sandstone is fai rly shaly, and this factor, plus the "gas effect", particularly on the neutron, would reduce the apparent porosity to an actual value nearer 20%. There is good "cross-over" separation between the neutron and density curves, indicating probable gas. The Barrow gas sand was drill-stem tested from 1,947 to 2,100 feet with the recovery of gas at a rate of approximately 200 MCFPD. A later production test established a gas potential of approximately 2.5 MMCFPD (see appendix on drill-stem test). The Sag River Sandstone had hydrocarbon shows, as reported from the wellsite. Only 17 feet of the sandstone was penetrated, and lost-circulation conditions prevented coring," testing, or logging of the interval. CONCLUSIONS The South Barrow No. 14 well failed to achieve one of the major objectives. By losing circulation, and thereby failing to core, test or log the Sag River Sandstone in South Barrow No. 14, the question of possible oil production from that formation must await further evaluation by the drilling of an additional well. There is likely additional gas production which could be obtained from th ree sandstones in the lower pa rt of the "Pebble Shale"; however, the thinness of the sandstones and their shallow depths (1576-1654') would likely suppress both the reserves and the deliverability. Additionally, gas hydrate problems, associated with low reservoi r temperatu re, might create production problems. The production test of the Lower Barrow sandstone (2.5 MMCFPD) confi rms that this zone is capable of providing an additional source of gas for the village of Barrow. 10 I I I I I I I I I I I I I I I I I I I . .

I I MEMORANDUM May 17, 1979 I TO: J. M. McCarthy FROM: S. K. Lewis I SUBJ: Production Test, Upper Barrow Sand, South Barrow Well No. 17 I The Upper Barrow Sand was perforated in Barrow No. 17 from 2038' to 2048', from 2054' to 2065', and from 2080' to 2088'. Perforations were at four shots per foot, using a 4" Hyperjet II gun. I After clean up, the well was tested. Testing consisted of an 8-hour Stabilized One-Point flow, a 24-hour buildup, an Equal Time Two-Point flow, and a 72-hour buildup. Back pressure analysis was performed on the three flow periods. I Reservoir analysis was prepared on the stabilized drawdown. Data, calculations, and resultant calculated values are presented below. Back Pressure Analysis I The backpressure slope was established from the Equal Time Two Point flow data. Absolute Open Flow was based on the Stabilized One-Point flow. I Backpressure Parameters n 0.659 AOF 132 McF/D I Drawdown Analysis I The drawdown analysis technique was based on the semilog plot of Pwf vs log Tp and the pressure equation: Pwf : Pi - 28984 q µgBg [log Tp + log k. -3.2275 + 0.86859 sl kh . Øt,¡gCtrw ~ J I Reservoir parameter analysis was based on test results and values of ø, Sw, and h derived from the H. J. Gruy log analysis as published in the Reservoir Engineering and Geologic Study of the East Barrow Field on December 20, 1978. I Calculated Reservoir Parameters I Flow Capacity ~ kh = 1.233145 md.ft.

I I J. M. McC<lrthy -2- May 17, 1979 I Conclusions Based on well performance while being tested and the attached test an<llysis, it is concluded that the Upper Barrow Sand, as penetrated in Barrow Well No. 17, is not a commercially producable zone. I All estimated ultimate Recoverable Reserves in the Upper Barrow Sand which have been assigned to Barrow No. 17 should be removed from current reserve estimates. Based on 640 acre spacing, this would result in a Recoverable Reserve cut of .440 BCF. I I I Copy to: Bob Lantz I I I I I I I I I I 0-2 I I I I I I I I I I I I I I I I I I I I I . .

That is a sub-sea datum of -2078; highest structural point established on L. Barrow sand (well 19) is -1990, giving a gas column about 88 or 90 feet thick. Analysis of gas produced from well 19 indicated about 12% Nitrogen, whereas gas from well 17 had less than 1% Nitrogen. Well 12 had about 7% Nitrogen. The meaning of this information is not clear, but may be related to faulting of the Barrow sand reservoir. Additional information may be forthcoming from the high resolution seismic program of last winter, and certainly from additional drilling. Reservoir quality of the L. Barrow sand does not seem to vary widely among the 4 wells drilled to date in the East Barrow field. The thick- ness varies only from a miximum of 25 feet to a minimum of 19 feet, with downdip wells having thicker sections. It appears to me that well 16 may have crossed a reverse fault. I sug- gest you look at the Gamma-Sonic, and see if you think the section 1750-80 might not be repeated at 1930-60. Hopefully the high resolution seismic will also clarify the possible faulting in the 16. H. J. Gruy and Associates have proposed to have some special core analyses performed on cores of L. Barrow sand from well 17. The material will be shipped to Core Lab in Dallas this week. The information will ,serve to increase the accuracy of the reserve estimate of East Barrow which they will prepare in the near future. There may be a variation of a few feet on some logs for formation tops, and some of you may have already called a top at a different depth. If it is close, can we agree to the calls listed here? If you think the difference is important, let me know and we will argue about it and maybe change the call. If the tops listed here seem close enough to you who will_be using the logs of these wells, we can probably save arguments and misunderstandings if most of us, at least, use the same calls in our mapping of the L. Barrow (top and base), Sag River top, and top of Argillite. Incidentally, I am a little confused by the telescoping substructure on Brinkerhoff rig '31; it was evidently 18 feet high on well' 16 (30-12 = 18); 26 feet high on well 17 (33-7 = 26); and 20 feet high on well 19 (30-10 = 20) Does anyone know the reason for this? 2 . .
