'R ALAS KA ENERGY AUTHORITY March 9, 2015 Commissioner Cathy Foerster Alaska Oil and Gas Conservation Commission 333 West 7th Avenue Anchorage, AK 99501 Re: Pilgrim Hot Springs Geothermal Wells Docket No: OTH-14-019 Dear Commissioner Foerster: The Alaska Oil and Gas Conservation Commission (AOGCC) has requested that the Alaska Department of Commerce, Community, and Economic Development (DCCED) submit a plan to suspend or plug and abandon six geothermal wells: Pilgrim Springs 1 - 5 and Mary's Igloo 1. The Alaska Energy Authority (AEA) is working on behalf of DCCED to develop a plan for these wells in compliance with 20 AAC 25.105 and 20 AAC 25.112. Alan Baldivieso, AEA geothermal program manager, has consulted with Patricia Bettis and Guy Schwartz at AOGCC to gather information and outline the steps required to plug and abandon all six wells. Alan has also contacted representatives of local landowners to confirm this is the preferred outcome. Based on these conversations and recommendations from AOGCC staff, AEA proposes to solicit bids through AEA's procurement process and select a contractor to perform the work; submit applications for sundry approval for the six wells to AOGCC; plug the wells according to the accepted plan with work estimated to be completed by September 30, 2015. I understand AOGCC staff has voiced support with the proposed course of action. Please let me know if you require additional information.

We have gathered substantial historical information and believe a proposed plan for the wells with the current project proponents is the solution although it remains unclear as to the specifics of DCCED's current responsibility and best path forward. Any action regarding the wells for which DCCED is listed as the operator appears to require coordination with the land owners Unataaq and Mary's Igloo Native Corporation. Regardless, pending completion of this research and sorting out these responsibilities, we would like to request a 60 day extension. We understand that ACEP has been or will be in contact with you regarding the four wells for which ACEP is the operator of record. Please feel free to contact me at any time regarding this matter.

The Alaska Energy Authority (AEA) is working on behalf of DCCED to develop a plan for these wells in compliance with 20 AAC 25.105 and 20 AAC 25,112. Alan Baldivieso, AEA geothermal program manager, has consulted with Patricia Bettis and Guy Schwartz at AOGCC to gather information and outline the steps required to plug and abandon all s>x wells. Alan has also contacted representatives of local landowners to confirm this is the preferred outcome. Based on these conversations and recommendations from AOGCC staff, AEA proposes to solicit bids through AEA's procurement process and select a contractor to perform the work; submit applications for sundry approval for the six wells to AOGCC; plug the wells according to the accepted plan with work estimated to be completed by September 30, 2015. I understand AOGCC staff has voiced support with the proposed course of action. Please let me know if you require additional information.

I spoke with Chris and he sent the attached report detailing the repairs that the University had done to some of the wellheads. Based on the conversation I had with Guy this morning, the application for sundry approvals will need to include specifics from the contractor that is ultimately selected to perform the work. I have identified several contractors that are familiar with the Pilgrim Hot Springs wells, but will need to accept bids through our procurement process prior to awarding the contract. I anticipate that the earliest the work can begin will be in July, although the road to the site may be clear of snow earlier than usual this year. I will specify that the work be completed by Sept 30, 2015. Is this approach to plugging and abandoning the 6 wells acceptable?

We have gathered substantial historical information and believe a proposed plan for the wells with the current project proponents is the solution although it remains unclear as to the specifics of DCCED's current responsibility and best path forward. Any action regarding the wells for which DCCED is listed as the operator appears to require coordination with the land owners Unataaq and Mary's Igloo Native Corporation. Regardless, pending completion of this research and sorting out these responsibilities, we would like to request a 60 day extension. We understand that ACEP has been or will be in contact with you regarding the four wells for which ACEP is the operator of record. Please feel free to contact me at any time regarding this matter.

The Commission is currently reviewing records for the purpose of identifying Alaska wells that have not been properly plugged and abandoned, and which thus may constitute safety or environmental hazards. Our records reveal that the wells identified above require remedial action to bring them into com- pliance with current Commission regulations. This remedial work will include cementing the wells in accordance with 20 AAC 25, Article 2. AOGCC is contacting you to request assis- tance in identifying current property ownership so that the required action can be taken. The Commission is also sending copies of this correspondence to the Catholic Church Fairbanks Diocese, to the entiy identified as Mary's Igloo, and to Mr. Steve Haagenson, Executive Director of the Alaska Energy Authority, to make them aware of the potential hazards presented by these wells. It is our intention to have the responsible well owner properly plug and abandon the wells. Should the owner fail to do so, then AOGCC intends to contract to plug and abandon the wells, reserving the right to hold responsible parties financially accountable for costs incurred. If you have questions regarding this finding, please contact Mr. Winton Aubert, Senior Engineer, at 907-793-1231 or winton.aubertai alaska. mov.

Subsequent to receiving the letter, AEA's Mike Harper conferred with Winton Aubert of your office. To the best of our knowledge, there has been no significant activity at Pilgrim Hot Springs since 1982. Our brief research shows that the only interest has been potential development of the geothermal hot springs in the area. However, most significant is the ownership of this parcel containing the wells. It is our understanding that Pilgrim Hot Springs is owned by the Catholic Church for surface estate while the local Native Corporation, Mary's Igloo, is subsurface owner. If you desire further information about land issues you may wish to contact Irene Anderson of Bering Straits Native Corporation in Nome. There has been talk of further research and exploration with the Mary's Igloo group possibly partnering with Alaska Center for Energy and Power at UAF. There is data that one can easily attain through the internet, but i have included two reports that will provide some background. If you desire further information please feel free to contact David Lockard, PE with our office at(907)771-3062.

The years associated with the drilling from "Division of Energy and Power" is probably old AEA nea APA (Alaska Power Authority). This is an interesting puzzle and I was not aware of this deadline or requirement prior to your email earlier today. It will take us at least a day to close the loop with UAF and come up with a plan, we are researching our library on old documentation. I agree with you, we need to apply for an extension. Patricia — do you know why this was not sent to AEA directly? Do the original documents from 1979 and 1982 mention Alaska Power Authority (I think the name change to AEA happened in 1990)?

The purpose of our project, funded primarily through the Department of Energy, is to test the validity of an innovative geothermal exploration technique which involves an advanced airborne infrared survey. To verify this technique we will conduct ground truthing using more traditional geophysical and geologic techniques, as well as collection of new data from six existing wells which will all be used to develop a conceptual model of the site. Eventually, we plan to confirm this model through the drilling of two 500ft gradient holes and two 2500ft confirmation holes to identify the recharge point for the hot springs and measure total heat loss to the surface to correlate to our airborne infrared data. Please let me know if you need any additional information, I am happy to provide it.

This area is governed by Conservation Order No. 159, issued September 12, 1979, which requires a permit to drill from the Commission for "all wells to be drilled or borings into the soil for any purpose and to any depth in Sections 29, 30, 31, and 32, T4S, R30W, KRM, Sections 35 and 36, T4S, R31 W, KRM, and Sections 2,3,and 4, T5 S, R31 W, KRM..." Three of these wells, Pilgrim Spring 1, 2, and 3 received permits to drill during 1979 (Permit Nos. 1790780, 1790850, and 1790900). Commission well history files indicate that Pilgrim Spring 1 and 2 were drilled to approximately 150' measured depth and suspended on November 25 and 20, 1979, respectively. There are no records in the Commission's well history file 1790900 to indicate that Pilgrim Spring 3 was drilled. During the summer and fall of 1982, Woodward -Clyde Consultants (Woodward -Clyde), under contract to the Alaska Division of Energy and Power Development, conducted an intensive drilling and testing program at Pilgrim Springs.' The initial well drilled was Pilgrim Spring 3, which had been previously permitted by the Commission. This was followed by the drilling of three additional, unpermitted wells: Pilgrim Spring 4, Mary's Igloo 1, and Pilgrim Spring 5. The results of this program are summarized in Woodward -Clyde's 1983 report, a copy of which has been placed in well history file 1002740. In 2010, Peter Illig of the Alaska Center for Energy and Power at the University of Alaska, Fairbanks conducted a reconnaissance trip to the site to Pilgrim Springs to locate and determine the status of the existing geothermal wells.2 Descriptions and photos of each wellhead indicate that all six wells are shut- in rather than suspended, as indicated by artesian flow and mineralization. The exact location coordinates for these wells are problematic. Coordinates for Pilgrim Spring 1, 2, and 3 listed as footages from section lines on the permits to drill were converted to latitude/longitude using the Commission's RBDMS database. These coordinates are shown on the accompanying satellite photograph by small yellow squares (Figure 1). Latitude/longitude coordinates stored in the RBDMS 1 Woodward -Clyde Consultants, 1983, Phase II: Results of Drilling, Testing and Resource Confirmation, Geothermal Energy Development at Pilgrim Springs, Alaska, Contract 82-0782 with the Alaska Department of Commerce and Economic Development, 62 p. 2 Illig, Peter, 2010, 6-29-2010 Preliminary Reconnaissance Trip Report, Pilgrim Hot Springs Geothermal Exploration, Alaska Center for Energy and Power. 0 0 Coordinates provided by Illig in UTM, meters, when converted to NAD 83 lattude/longitude using CorpsCon 6.0, plot at the locations indicated by yellow stars on Figure 1. Well locations spotted by Illig on an air photo that accompanies his 2010 reconnaissance trip report are more difficult to translate to the satellite photo. It appears as though Illig's photo is rotated about 20 degree clockwise from north and is also severly stretched along its north -south axis. A prolonged trial and error session was needed to squeeze and rotate this air photo to approximate a close match of the streams and lakes to the satellite photo. But the match is not perfect: lakes and stream meander loops do not match closely between the photos. The well locations from the best -match fit between the air and satellite photos are indicated by the red circles on Figure 1. Accompanying Woodward -Clyde's 1983 report on the results of drilling and testing is a site map that, when uniformly scaled, matches the satellite photo almost exactly. The locations for the Pilgrim Spring and Mary's Igloo wells are indicated on Figure 1 by small, blue circles. When uniformly scaled, the USGS topographic map of this area also nearly perfectly matches the satellite photo and Woodward - Clyde's map. This topographic map is the source for the yellow section lines depicted on Figure 1. Because of the nearly exact match between the map accompanying Woodward -Clyde's 1983 report, the USGS topographic map and the satellite photo, and because Woodward -Clyde field personnel spent weeks in the field (rather than the single day spent by Illig), it is judged that the most accurate locations for the Pilgrim Spring and Mary's Igloo wells are those mapped by Woodward -Clyde. Based on these locations and the section lines derived from the USGS topographic map overly, the best estimates for the well locations are presented in the table, below.

These wells were presumably drilled prior to 1979, when Conservation Order #159 established AOGCC jurisdiction over the Pilgrim Hot Springs area (hence, drilling permits were not required). Well files currently exist for PS -1, PS -2, and PS -3, respectively. Only recently did the AOGCC learn of the existence of three additional wells. Utilizing a reconnaissance trip report prepared by Peter Illig of the Alaska Center for Energy and Power (ACEP), the AOGCC determined that the three wells previously known were in -fact wells PS -1, 2, and 3, respectively. Wells identified as PS -4, PS -5, and MI -1 (in the ACEP report) are the previously unknown wells. The information collected about these wells was collected and their respective well files were created.

Notes on Geographic Coordinates When acquiring GPS points for this project, we determined it would be best to use Universal Transverse Mercator (UTM) as normal distances between lat long lines are distorted due to the high latitude arctic location of the site. UTM provides an easy to use square grid system. For this report I used NAD 1927 Alaska (5003), and the units are in meters. Please make sure that when using coordinates in the area to use this coordinate system. Site Overview Pilgrim Hot Springs is road accessible, although the last mile or so is in bad shape. There is a fair amount of stable ground in the surrounding area, and it seems possible to access all 6 existing wells with equipment needed to replace the wellheads without the aid of helicopter during appropriate times of the year. There are numerous historic buildings, including the church, dominating the north section of the area. To the south is the MI -1 (see figure 7), with the Mary's Igloo well being furthest west. Well Descriptions We were able to locate all 6 wells during the trip, and have provided current descriptions of their condition below, with images from the wellheads included in Figures 1-6. Figure 7 shows the relative locations of all the wells. My colleague, Dan Brotherton, is preparing a plan to refit wellheads for all but one or two of these wells so they can be accessed to collect additional data. We have located the original well completion diagrams and other critical information related to the original drilling program in the report 'Results of Drilling, Testing, and Resource Confirmation — Geothermal Energy Development at Pilgrim Hot Springs, Alaska' prepared by Woodward -Clyde Consultants in 1983. This report will be very helpful in developing a plan to rework the individual wells as needed. PS -1 (0503536mW 7218438mN) This well is located furthest north (closest to the church and nearest the main trail). It may very well be the hottest of the wells and appears to have significant artesian flow as evidenced through the leakages. The wellhead has a thick layer of silicious deposits on the exterior which has capped some of the leaks. This well will need to be refitted for further use. PS -2 (0503477mW 7218374mN) Located SW from PS -1 is PS -2. This well seems to be in fairly good shape, and is marked by a large white PVC tube. It is located close to the ground, and does not seem to be leaking. It does not appear necessary to replace this wellhead, although access with appropriate instrumentation may necessitate retrofitting a 2in valve to the wellhead. PS -3 (0503411mW 7218346mN) West of PS -2 is PS -3. It stands out clearly when surveying the area due to its higher wellhead compared to the others. It is also leaking, and will require refitting in order to access the hole. The silicious seal has sealed past cracks in the metal, however there is a constant artesian flow from at least unsealed leak. PS -4 (0503475mW 7218298mN) This is the well which feeds the main hot tub on the property. It leaks considerably, and has a few tubes connected to the wellhead which are presumably used to feed the tub. As with all the wells described thus far, it will require extensive work to be fully operational. PS- 5 (0503478mW 7218122mN) PS -5 is the located furthest to the south. Additionally, it is in the best shape of all of the wells. The valves seem to be operational, and there is little rust on the wellhead. Hot water comes out of the valve that we tested which is attached to a garden hose. Getting to the well should not present an issue, however it should be noted there is a lake that was covered with a floating mat of grass that both Dan and I fell into. MI -1 (0503262mW 7218327mN) MI -1 is located furthest west on the field. It was drilled for a hot water source on behalf of Mary's Igloo Native Corporation (MINC). It has extensive damage to the upper part of the well, where a large crack can be seen in the wellhead. The flow is constant from the crack, with much of it being sealed with silica. This wellhead should also be replaced if it is to be accessed in the future for research or development purposes. Conclusions Dan Brotherton will be writing a report suggesting further steps to be taken on the existing wells to make them operational. This report will be shared with the well owners, Unaatuq, LLC and MINC. The next step will be to map culturally sensitive areas (grave sites, historical buildings, etc.) and property boundaries. This task is scheduled for late July or early August. Prior to this trip we will set up a phone conference with all the parties involved to address questions and concerns regarding that trip, to go over schedules, and to develop a backup plan. Figure 7, which is located on the next page, includes all of the well locations and some of the buildings on the property. Once more information on historic sites, and other important cultural features are identified, they will be added to this map. Any future drilling objectives will take all of this information into account so that any effects are minimized.

This trip took place September 13th -18th. The goal was to stop the wells from leaking, and make them accessible for instrumentation as part of the DOE funded project 'Innovative Geothermal Exploration of Pilgrim Hot Springs, Alaska'. This report details the work performed on the individual wellheads during the September trip, which included replacing the gate valves on 4 of the 6 wells, including PS -1, PS -3, PS -4 and MI -1. At this time, none of the wells are leaking to the surface although there are still weak points which need to be addressed in the future. Recommendations for future work are outlined in this report. The team performing the work included Dan Brotherton from Arctic Drilling, Richard Eggert, and Max lyapana from Bering Straits Development Company (BSDC), and Markus Mager from ACEP. For each of the four wellheads that were repaired, the team removed the existing gate valves by pumping down the water level in order to access the well and installing new, stainless steel valves. A detailed work description for each well can be found on the following pages. The team did not alter the configuration of the wellheads except for installing an additional fitting on top of the blind flanges capping the gate valves that can accept a 3" stainless standpipe with a tee and a valve to allow future installation of monitoring and logging equipment. A 1" access port with a plug was also built into the top of the blind flange. We recommend installing chains and locks on all the new valves and that all valves should be tested for functionality (opened/closed) at least once a year. Winterization of all the wells is necessary in order to prevent freezing and cracking of the gate valves. A plan for winterization has been forwarded in a separate communication that is attached to this report. Mobilization All new valves (6), parts, tools and supplies, totaling 3,842lbs, were purchased or rented by ACEP and shipped to Nome via Northern Air Cargo (NAC). Additional heavy equipment such as 4 wheelers, trailers, a bobcat and an air compressor were rented in Nome from BSDC. All parts, tools and equipment were transported to the side on September 13th and 14th and staged at the central staging area (Figure 1). Repair work began on the 15th, and tH was completed on the 18 central staging area for repair work Figure 1. Central staging area for repairs. PS-4 (Completed September 14-15`') hottub 9W. PS -4 supplies the water for the hot tub from a tin lower valve. The well was leaking from a % inch hole in the blind flange on top of the 10in well gate valve and from the corroded 2in valves on each side of the 10in casing underneath the 10in valve (Figure 2). The lower bolt flange of the 10in valve was covered with mineral buildup and corrosion scale. There was a small pond around the well at the level of the 2in side valves from the constant leaking and overflow from the tub. The team laid down timbers and planks to create a stable work platform and removed mineral build up and rust scale from the lower bolt flange (Figure 3). After various failed attempts to release the old 10in valve from the well flange, the bolts had to be cut off with a torch (Figure 4 & 5). 3 PS -4 mineral buildup and corrosion scale �_ 11Y I 111 IMW 1' i leaks Figure 2.

Removing gate valve with Bobcat — note artesian flow from well. PS -4 has an inner Bin and an outer 10in casing. The outer casing is corroded and thin. The 8in/10in annulus (space between the two casings) continued to produce water after the water level inside the Bin casing was drawn down. This indicates a likelihood that they are set to different depths and water is produced from a different production zone in the annular space than through the main hole. In order to weld on new tin nipples, this water would need to be drawn down. We were able to partly draw this water down with a lin suction tube, but it was ultimately decided to not risk changing the tin nipples after it was determined they are corroded but still sound (probably just as sound as the casing). Dan was not confident that the casing could be welded given its state of deterioration, so rather than risk creating a difficult to stop leak, the original nipples were left in place and only the tin valves were replaced with new stainless 2" valves (Figure 6). PS -4 new valves New 2in valves but nipples they attach to were not replaced N, l� �s Corroded old casing and the two nipplesare still weaknesses Figure 6. New valves. The flange on this well is partly eaten away but still appears to be sound. The well is artesian and produces clear water. We installed a new 10in stainless steel valve with reducer flange on top connected to a 3in threaded nipple with a stainless cap. The well has no visible leaks and has been re -connected to the hot tub via one of the new 2in valves. Further repairs on this wellhead will be needed in the near future. The 10in casing and the 2in nipples are thin and will eventually start leaking with no way to control or stop the flow. Dan recommends that the 8-10in annulus be cemented from the bottom up to the top via tremie pipe which would seal off the corroded outer casing from the well water and would extend the life of the well. We are also recommending locks on the 2in valves to guarantee flow to the hot tub, prevent accidently closure (or opening) and to prevent well freeze up since this well will presumably not be shut in through the winter. If this is the case, it is imperative that the 2in valve remains open to prevent the new gate valve from freezing. 1i PS -3 (Completed September 15 -16th) Prior to repairs, this well was leaking through the standpipe at the top of the well and later, after we started to remove buildup and scale (Figure 8), from a hole in the side of the 10in valve (Figure 7). We were unable to plug this leak so we dug a sump hole to drain the fluid and temporarily pump it away from the well and surrounding work space.

Removing scale and buildup. There was significant corrosion to several of the bolts connecting the existing gate valve to the wellhead flange, which necessitated cutting them off with a torch. We were able to drive out some of the bolts once they were cut, but several posed additional challenges and had to be removed in chunks. The torch was damaged during this process. Eventually we were able to remove the old 10in valve and replace it with the new stainless valve and bolts. The lower flange of the wellhead is severely corroded and the new flange bolts are exposed. The flange thickness is about half of original thickness and there is barely enough material left to secure new flange bolts (Figure 9). The well was completed with a new capped gate valve and blind flange, with a 3in nipple and cap. There is a tin valve below the flange which was left in place as it is not currently leaking. Dan was not confident the well casing is sound enough to permit replacement of this valve.

PS -3 is hotter than PS -4 and produces clear water. There is also a 6in inner casing in this well that comes to the top of the 10in casing. Once the old valve was replaced, there were no visible leaks. Figure 10 shows a comparison of the old PS -4 valve flange and the old PS -3 valve flange. PS -3 & PS- -�.. old Valves a. F Figure 10. Old loin valves from PS -3 and PS -4. Note severe corrosion on lower PS -3 flange. Further repairs will be needed to this wellhead soon. Dan recommends cementing the 6-10" annulus from the bottom up with tremie pipe so that the side valve can be removed and the main well flange can be replaced. This will protect the well from a permanent leak if one develops from the corroded casing. MI -1 (Completed September 16 -18th) This well is located on adjacent Mary's Igloo Native Corporation land. The top of the 10in gate valve was split in half, probably due to a freeze break. We were able to open and close the old gate valve but could not completely stop the flow of the well. MI -1 is colder than PS -4, and the water temperature of this artesian well appears to fluctuate. When flowed for a short period of time it produced gray, silty fluids. The well has no visible inner well casing. Due to leaks in the wellhead, a small pond had formed around the well several inches deep. We cleaned out an existing trench leading away from the well and the pond drained away to ground level. We built a work platform around the well and removed mineral build up, rust and scale from the bolts. Dan cut the bolts and drove them out with the torch. We removed and replaced the 10in valve with new stainless steel valve and bolts (Figure 11). The new gate valve is capped with a blind flange with 3in welded nipple and cap. 9 IMAM MI -1 new valve Figure 11. Work commences on MI -1. Note artesian flow prior to pumping. Prior to repairs, the well was also leaking from several holes corroded through the casing below the gate valve flange. These leaks continued after installing, capping and shutting the new gate valve. The casing is paper thin midway between the flange and the cement. Dan welded a sleeve around the casing from about 2in above the cement level up to the flange, totaling about 14in. In order to weld on the sleeve, he completely removed the side valve, nipple and weldolet from the 10in casing. The sleeve stopped the leaks temporarily but the casing below the sleeve is thin and remains a significant weakness (Figure 12). Dan recommends installing a 6in inner casing and cementing the annulus from the bottom to the top via tremie in order to prevent further leaking once the casing corrodes further. KAI 1 MI -1 repair work on casing installation of new sleeves Figure 12. Casing conditions of MI -1. 10 PS -1 (Completed September 18t) PS -1 is the hottest of the repaired wells. This well was buried past the valve handle and covered with several inches of mineral buildup. Before repairs, it leaked out of a corroded two inch elbow from the top of the wellhead, as well as the remains of a tin valve and a lin hole in the top of the well cap (Figure 13). These holes were plugged with sticks driven into the openings after some of the mineral build up was removed. We then excavated around the well to just below the lower valve flange covering an 8ft by 10ft area, dug a sump hole for the water pump and laid down blocking and timbers for a work platform. We removed the mineral build up and de -scaled what remained of the bolts (Figure 14). PS-1� �- before repair work starts Figure 13.

When the gate valve was removed, it was evident that the lower flange was almost completed corroded away with no bolt heads remaining and the bolt threads visible from the side of the flange. We used the torch to remove the bolts, removed the old gate valve, cleaned up the flange as much as possible, and installed the new 6in stainless valve topped with a stainless blind flange, 3in nipple and cap (Figure 15). new valve Figure 15. New valve installed on PS -1. Note collapsed suction hose due to high temperatures. This well has a 4in inner casing inside the 6in outer casing, and does not have any lower casing tin valves. There is not much left of the well flange, just barely enough to bolt on the new valve. The well is sealed and does not 12 leak at this time. We backfilled around the well but not to the previous level so it is possible to access valve handle. We left the remaining dirt piled to the side of the excavated area. Dan recommends installing a short (18in) spool section underneath the new gate valve to raise the valve above ground level and permit the well to be backfilled to ground level. This would also eliminate the standing water around the well, which is now below grade. He also recommends cementing the 4in-6in annulus and welding on a new casing flange in order to prevent future leaks. PS -2 This well is buried but inaccessible with rubber tired backhoe. We did not attempt to dig up this well. The wellhead valve is not corroded or leaking. We will attempt to make it accessible for instrumentation in 2011. Figure 16. PS -2 buried but not leaking. We will need to excavate and replace valve before this well can be accessed with instruments. PS -S This well is also not corroded or leaking so we did not replace the valve at this time. We will attempt to make it accessible for instrumentation in 2011. 13 Figure 17. PS -5 still appears to be in good shape, but not accessible by instrumentation. Winterization Plan for Wellheads (Dick Benoit and Gwen Holdmann) The trick to keeping a wellhead from freezing and then breaking during sub freezing weather is to inject a liquid that is both less dense than water and has a very low freezing point into the wellhead. This fluid needs to be environmentally benign so that when (not if) it is spilled or leaks out of the wellhead it does no environmental damage. Typically a food grade vegetable oil has been used in the lower 48. A small pump is used to pump the oil into the highest opening in the wellhead but if the pressures are very low even a hand operated pump may be enough to do the job. We expect this to be the case for the Pilgrim wells. This pump obviously needs to be able to overcome the internal wellhead pressure and can pump at low rates. You will need to know how much oil has been pumped into the wellhead. Enough oil needs to be pumped into the wellhead to push or displace the water down the well to a point below the freezing level, which is probably not more than a few feet. Therefore, it is necessary to calculate the volume of the wellhead above ground and a few feet of wellbore below ground. We expect this might amount of a few tens of gallons per well. It is important to check the wellhead for leaks, no matter how slow, before injecting the vegetable oil. If the oil leaks out of the wellhead then the water will flow back up in the wellhead and freeze. We recommend doing this on the 4 wells with new gate valves prior to hard freeze-up. 14
