Sincerely, tach Sayers Contracted Engineering Manager, OCS (281)615-1408 From: Zach Sayers Date: May 6t'', 2019 LELLO L!0"] RE: Gubik Test Well #2 Executive Summary • • • •„ Well Backaround The Gubik Test Well #2 was drilled by the U.S. Navy in 1951. This well was drilled to a TD of 4,620' MD with the 11-3/4" casing string having been set at 810' MD. Producible quantities of gas were found, then the well was left with two downhole cement plugs below the productive zones. While tripping out of the hole in preparation for a third plug, the well suffered a blowout. Once the blow-out was contained, the well was filled with fresh water and a wellhead was installed. During pre abandonment inspections it was noted that a small amount of gas was leaking from the wellhead. Fresh water was left in the wellbore above the upper most cement plug; however the Oct. 2018 visit showed gas production to surface indicating that a solid ice plug is not in the well. The max pressure observed at surface was 280psi. This well has extensive surface debris and drilling muds associated with it, including one nearby rathole. Operations Summary: The existing well was entered on 2/22/2019 with slickline tools and found ice in the wellbore at 135'. Slickline made attempts to bail through the ice plug while methanol was pumped from surface. Slickline tools were unsuccessful at breaking through an ice plug to open casing. At 170' a slickline bailer pulled out of the rope socket and was left in hole. All fishing attempts were unsuccessful, and the tool was left in the hole. The well was then lubricated and bleed to kill the well, while fresh water was squeezed into the well and allowed to freeze. The well was monitored for explosive gasses and an exception was made to cut the existing wellhead off so that a larger bore wellhead and subsequent BOP could be nippled up. After BOPS were tested and the rig was moved over the well, additional attempts were made to fish the slickline tools with no success. A drilling BHA was made up and ran into hole to ream and thaw the wellbore. After 20' of progress, erratic torque and abnormal drilling parameters prompted the team to pull the BHA out of hole. A cone of the tricone bit was found to be loose indicating that the slickline fish was damaging the bit during rotation. The decision was made to thaw out the wellbore with the 1.90" workstring with a mule shoe. Initial fluid used was a 9.5 ppg NaBr fluid. Gas cut returns, gas bubbling, and surface methane readings prompted the team to weight up from 9.5 to 10.5, then 11.0, then 11.5, 12.0, and finally 12.3 ppg before operations could safely control gas break out at surface. From Surface to 1,200' TVD thawing and clean out operations occurred in an underbalanced fluid column to the 1792ft gas zone, due to the constraints of the existing wellbore obstructions and requirement to get heavy kill weight fluids placed deep in the well to provide adequate hydrostatic column. Due to this under -balanced situation, gas flow had to be controlled at surface constantly as the workstring was lowered into the wellbore. The well was thawed down to the 11-3/4" surface casing shoe at 810' MD. Almost continuous wellbore flows occurred while breaking through ice plugs and required circulation out through the surface control equipment at surface. Operations were halted to develop a contingency plan forward for potential loss circulation as the BHA enters the open hole. An additional 112,000# of NaBr salt was brought to location to provide loss circulation contingency to keep the hole full if losses occurred. On 3/09/2019 the workstring thawed below the 11-3/4" casing shoe into the open hole. Continual kicks were observed as the workstring deepened into the open hole. The most notable kick occurred at 1,200'. The kick was circulated out of hole and on 3/12/2019 the well was deepened to 1,290' before taking loss circulation. The decision was made to place a cement plug at this depth rather than deepening the well further and risking a poor cement job caused by the dynamic fluids column of the loss circulation zone. From: Zach Sayers Date: April 251", 2019 • • • RE: Gubik Test Well #2 Executive Summary • • • • -" On 3/13/2019 a 32 bbl 16.0 ppg Class G cement plug was set in the open hole using the balanced plug method from 1,290 to 1,000' MD. On 3/15/2019 the plug was tested to 650 psi successfully with TOC confirmed at 995' MD. On 3/15/2019 a 32 bbl 16.2 ppg Class G cement plug was set in the open hole and across the 11-3/4" casing shoe using the balanced plug method from 910' to 720' MD. On 3/17/2019 the plug was tagged at 768' MD then a pressure test was attempted to 500 psi. After 10 minutes the pressure bleed off indicating that the cement was squeezed away into the open hole. The workstring was ran in hole and tagged the new TOC at 797' MD. A second plug of 16bbls was mixed and pumped from 797' MD to 661' MD using the balance plug method. On 3/20/2019 the TOC was tagged at 664' MD and pressure tested to 500psi successfully. An Artic Cement Platform was lowered into the cased hole and set at 167' MD. On 3/21/2019 a 20 bbl, 16.0 ppg cement plug was pumped from 167' to surface inside the 11-3/4" IA. The workstring was pulled out of hole and laid down. On 3/23/2019 the plug was tested to 500 psi successfully with TOC confirmed at surface. The remaining wellhead and stub of 11-3/4" casing were cut off and capped with an API marker plate 5' below ground level. The OA was confirmed to have cement to surface. The Conductor by casing jacket annulus was grouted with cement till flush with the cut-off level. The surface equipment was rigged down and removed from location. The well cellar area was back filled with fresh fill and all surface debris was cleaned from location. Operations were completed on 3/23/2019.

Efforts to close rams around drill pipe failed as mud and gas were blowing out at such a rate that it was impossible to see results. After the well sanded up it was found that the drill pipe had been lifted enough to free the slips and had dropped down the hole. The well blew wild and ignited in about 5 minutes: In only 3 or 4 minutes the rig collapsed. The well sanded up in a few hours, but enough gas from an upper sand was escaping from the casing to flame about 4-6 feet high. Two days after the original blowout, the well again blew out with volume and force about the same as the first time, but it again sanded up within a few hours and continued to burn with a flame about 4 or 5 feet high. Wreckage was cut away with a torch before extinguishing the blaze, in order to remove the Shaffer gates which were still usable. After the blaze was extinguished with carbon dioxide, the hole was filed with water. The 204 barrels of water required to fill the hole indicated that the top of the bridge was approximately at 1,800 feet. The only zone in this well which showed by formation test to have high-pressure, large volume gas was between 1,810 and 1,858 feet. Simpson Core test 16 At 800 feet gas ignited accidentally on Aug. 31, 1949. Pumped 600 gal water into hole but most of it blew out. Equipment moved. Melting of ice and sloughing around hole made funnel -shaped cavity 25 ft in diameter. Flame went out Sept. 2, 1949, although gas was still flowing. Water in hole was allowed to freeze, but the gas continued to flow. sown OCT 012014. 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 priman- regulator- 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-visitedin 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.

Gubik Test Well #2 is 17 miles east of Umiat and 55 miles south of Nuiqsut. It is approximately 2 miles outside of the National Petroleum Reserve in Alaska boundary. The last site visit to the Gubik Test Well #2 was in July 2012. Site Description: Gubik Test Well #2 is within the floodplain on the west side of the Chandler River [Figures 1-2]. Vegetation is primarily mosses, sedges, and willows. The willows are thick in the areas once disturbed by drilling operations. There are several well -traveled trails in the willows, likely created by the bears frequently observed in this area. A drill pad does not exist. The gravel bar and adjacent tundra provided a sufficient working surface. There are several large timbers remaining around the wellhead, as they once enclosed the wellhead [Figures 3-41. These timbers toppled over sometime between 2000 and 2002. A small, but steeply sloped pile of hardened bentonite is present approximately 15 feet to the west of the wellhead. Directly adjacent to that is a small pile of drilling muds. A minor amount of rusting metal debris is contained within the area between the two piles [Figures 5-6]. An open rat hole is located approximately 6 feet to the southeast of the well [Figure 7]. The rat hole has been thrust several feet out of the ground by an active freeze/thaw process. It was approximately 1 foot above ground level in 2002, but by 2012, the rat hole was sticking up nearly 5 feet. Surface Risk Assessment: High Justification: The Gubik Test Well #2 leaks a small amount of methane into the atmosphere, resulting in a possible impact to air quality. It is unclear whether the pile of bentonite clay was used or simply stockpiled. If used, then the clay could contain a small amount of trace hydrocarbons, which could have naturally attenuated over the long amount of time it has been present onsite. The Chandler River is less than 100 feet from the well, but the river has not been a threat to the well since it was drilled in 1951. That trend apparently will continue as the channel of the Chandler River closest to the well location is a secondary channel that is becoming cut off by the main channel [Figure 2]. There is no indication that the well has a negative effect on surrounding surface waters, nor is there any impacts to visual resources at this site.

BLM Open File Report 127 • May 2013 125 Gubik Test Well #2 SUBSURFACE INFORMATION Well Information Legacy Wells Summary Report Well History: Gubik Test Well #2 was spudded by Arctic Contractor on Sept. 10, 1951, and was completed Dec. 14, 1951, reaching a total depth of 4,620 feet. A very strong blow of gas was encountered while drilling, in excess of 8 million cubic feet per day, which eventually resulted in a blowout while attempting to plug this well. The well blow went wild and ignited, causing the drill rig to collapse. After the hole sanded up on its own, two days later the hole reopened and blew with the same force. After seveal hours, the hole once again sanded up on its own. After the flame was extinguished with carbon dioxide, the hole was filled with 204 barrels of water. A wellhead was put on the well and it was left in a suspended status. Upon completion, the well was junked and abandoned. The BLM conveyed the surface and subsurface lands with the Gubik Test Well #2 site to the Arctic Slope Regional Corporation on Sept. 27, 1995. The U.S. Navy set one cement plug at 2,300 feet prior to suspending the well in December 1951 [Figure 8]. Well Condition: A very small amount of gas is seeping where the bell reducer attaches to the adapter flange (just below the only valve). It is difficult to hear the seep unless standing adjacent to the adapter flange. • Wellhead Components: The wellhead consists of 1 single valve (closed) without any gauges. Geologic Setting: The Gubik Test Well #2 is on the south flank of the Gubik anticline, 240 feet to 270 feet structurally lower than Gubik Test Well #1. The drilled stratigraphic section is identical to that of Gubik Test Well #1, except for an additional 250 feet of younger Cretaceous rocks (Barrow Trail member of the Schrader Bluff Formation) at the top. The average dip of the beds from the top of the hole to the bottom of the Seabee Formation is 6 to 7 degrees. In the undifferentiated Chandler and Ninuluk formations, the dip is 3 degrees. This lower dip may only be apparent due to the excessive hole deviation of 4 degrees recorded at 3,825 feet. The dip in the Grandstand Formation averages 4 degrees, but the normal fault (mentioned below) may affect it. Although only 200 feet of the Topagoruk Formation was penetrated in Gubik Test Well #2, the lowest two cores show an increase in dip to 13 degrees, similar to that of the Topagoruk Formation in Gubik Test Well #1. Excessively high dips are not present in Gubik Test Well #2. Slickensides were noted at 1,916, 4,252, and 4,415 feet. Approximately 200 feet of section in the middle of the Grandstand Formation present in Gubik Test Well #1 is missing in Gubik Test Well #2. This is possibly because the section was cut out by a normal fault at 4,270 feet. Another possibility is that the missing section represents an unconformity. Regionally, however, there is no evidence for an unconformity within the Grandstand Formation (Robinson and Bergquist 1958). Development Potential: Industry has shown interest in this general area, as exploration has occurred on neighboring State of Alaska lands. Gas is the primary commodity in this area, but development is not likely until the construction of a gas line occurs for transportation to market. Groundwater Resource: None. Fresh water aquifers are not present due to the thick, continuous permafrost in this area. Other Information: With the discovery of the well seeping a minor amount of gas, it is considered a well that will need to be plugged in the near future. 126 BLM Open File Report 127 9 May 2013 • Legacy Wells Summary Report Gubik Test Well #2 Subsurface Risk Assessment: i.�l � Justification: Gubik Test Well #2 is leaking a minor amount of methane into the atmosphere.

Mohr, chief of exploration for Arctic Contractors (written communi- cation, 1952): Gas deposits discovered in 6 sands between 1,066 and 1,875 feet in the Gubik 1 were found to extend down the structural dip to some undetermined points beyond Gubik 2. Assuming that gas extends down the dip to a uniform sea -level elevation on all parts of the anticline in each of these sands., the areal extent of the gas deposits would exceed 7,000 acres A seventh gas sand of "the Tuluvak tongue" in Gubik 1 does not carry gas as far down the structure as well 2, where it is found to be water bearing. An -eighth gas sand, at 1,905 feet to 1945 feet in Gubik 1, becomes impervious and nonproductive somewhere between 1 and 2. A tight sand, which might yield some gas if further tested,was topped at 3,242 feet in 1 and 3,513 feet in 2. An important gas sand at 3,460 to 3,615 feet in 1 is water bearing in 2 at 3,781 to 3,903 feet. An untested belt, or zone, of this sand extending from 1 to 2 and covering 4,800 acres of the structure, might yield gas, water, or oil over an extensive area of the anticline; but a third well about halfway down the dip be- tween 1 and 2 would be required to test the fluid content in this belt. The fact that good oil saturation was, found within a few hundred feet below this sand in the .2 well is a strong suggestion that this sand might carry an oil deposit between 1 and 2. The oil saturation found in the 2 well at 4,031 to 4,060 feet, and 4,233 to 4,254 feet, also signifies the possibility that these sands might be better developed and capable of oil production at some i TEST WELLS, GUBIK AREA, ALASKA other location on the Gubik anticline. Their stratigraphic posi- tion corresponds roughly to that of the Umiat pay sands. A significant feature of the basal part of the gas sand at 1,810 to 1,880 feet in Gubik 2 is the presence of true oil saturation and some free oil below the highly porous and permeable, gas -bear- ing part of the sand. If this represents a true gas -oil contact, as seems to be the case, then by drilling somewhat farther down the dip, the highly porous and permeable part of the sand should be found at the level of the oil and should yield prolific oil pro- duction. LOGISTICS A large working force was used to move the drilling rig about 1 % miles southeast from Gubik test well 1 to the site of Gubik test well 2. The rig was not unitized, and the season was bad for moving. However, Gubik test well 2 was ready to spud within a month after the completion of 1. One thousand and eight hundred tons of material, hauled by cat train, was used in drill- ing Gubik test well 2; 200 tons was flown in using the large airstrip at Gubik test well 1. An additional strip for bush planes was constructed near Gubik test well 2. The camp setup was similar to that of the first well - 2 quonset huts, 10 jamesway huts on sled runners, and 6 wanigans were used. The personnel, vehicles, and drilling equipment remained the same. The following materials were consumed during the drilling of Gubik test well 2: 564,000 gallons of water, 89,821 gallons of diesel fuel, 7,517 gallons of 72 -octane gasoline, 960 gallons of lubricating oil, 295 gallons of thread lubricant, and 358 pounds of grease. DRILLING OPERATIONS RIG FOUNDATION The derrick and drawworks were mounted on piling. The remainder of the equipment such as tanks, and pumps were mounted on timbers laid on the river gravel. DRILLING NOTES The following table is composed of selected notes from the drilling records.

Started out of hole intending to run in with 10% -in. bit and clean out to approximately 2,200 ft. Well started to flow mud and immediately went out of control with three stands in the slips. Closed blowout preventers around drill pipe in attempt to control well. After estimated 5 min of 0 Notes from drill records --Continued 255 gas blow, the well ignited and burned for approxi- mately 4 days, resulting in the destruction of the rig. Hole bridged itself near 1,800 ft and was filled with water above the bridge and allowed to freeze. Owing to the circumstances it was impossible to set plugs between the various gas sands above 1,800 ft; there- fore, there is nothing but a bridge of sand or cavings to prevent the movement of high-pressure gas from the 1,800 -ft sand upward to any of the various shal- lower permeable sands beginning at 1,134 ft. _ Com- pletion status: at the cellar floor there are an 11 �4-iri. landing base, 114 -in. landing spool, 12 -in. series 900, 104 -in: to 3 -in. sewage, and 3 -in. Hamer plug valve, 6,000-1b test. BLOWOUT After the first cement plug was placed at 2,260 feet, a second plug of 40 sacks was placed at 2,251 feet. After the second plug was in place, the drill pipe was pulled above the estimated top of the cement, and the circula- tion system was run for about 3 hours to clean up the mud. While pulling pipe to change bit, preparatory to running in to feel for top of plug, mud started to blow out when all but three stands were out of the hole. Efforts to close rams around drill pipe failed as mud and gas were blowing out at such a rate that it was impos- sible to see results. After the well sanded up it was found that the drill pipe had been lifted enough to free the slips and had dropped down the hole. The well blew wild and ignited in about 5 minutes. In only 3 or 4 minutes the rig collapsed. The well sanded up in a few hours, but enough gas from an upper sand was escaping from the casing to flame about 4-6 feet high. Two days after the original blowout, the well again blew out with volume and force about the same as the first time, but it again sanded up within a few hours and continued to burn with a flame about 4 or 5 feet high. Wreckage was cut away with a torch before extinguishing the blaze, in order to remove the Shaffer gates which were still usable. After the blaze was extinguished with carbon dioxide, the hole was filled with water. The 204 barrels of water required to fill the hole indicated that the top of the bridge was ap- proximately at 1,800 feet. . The only zone in this well which showed by forma- tion test to have high-pressure, large volume gas was between 1,810 and 1,858 feet. This zone was also the only one on the electric log about which there could be no question of the content being oil or gas. The long normal and lateral resistivities were a great deal higher than the short normal. The volume of fluid required to fill up the hole after it had bridged over following the blowout was the amount required to fill it from 1,802 feet to the surface. There can be little doubt that the gas blowout came from the sand between 1,810 feet and 1,858 feet. • 256 EXPLORATION OF NAVAL PETROLEUM RESERVE NO. 4, ALASKA, 1944-53 DRILL AND CORE BITS A total of 1,445 feet was cored (see pl. 16) using 68 bits, with 82.1 percent core recovery. Thirty-five drill bits were used, three 15 -inch bits, thirty-one 10% -inch bits, and one 7% -inch bit, with an average of 90.5 feet drilled per bit. DRILLING MUD Arctic Contractor's petroleum engineer (written communication 1952) states that— A water -base mud was used to drill to total depth. A 75 pound - per -cubic -foot water-Aquagel drilling fluid was mixed initially; Baroid was used as the mud -weighting agent. Sodium tasmate was used to maintain viscosity at a desirable value; sodium bicarbonate to combat cement contamination; and carboxy- methyl cellulose to control water loss and stabilize the drilling fluid. A total drilling time of 86 days was required to complete the well. This treatment maintained an excellent drilling fluid throughout the period. The mud and tanks were cleaned while the well was standing cemented at 810 ft, and only the mud remaining in the tanks at this time was dumped. In treating the mud, 945 sacks of Baroid, 118 sacks of Aquaggel, 1,510 pounds of quebracho, 190 pounds of sodium bicarbonate, 430 pounds of Driscose, and 150 pounds of tetrasodium pyrophosphate were used. Following table shows the approximate amounts used, by. depth.
