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

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 l - 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.

Thank you, Patricia. 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?

Re: Wells Pilgrim Spring I (PTD 179078), Pilgrim Spring 2 (PTI) 179085)
Dear Ms. Anderson:
In October, 1979 the Alaska Oil and Gas Conservation Commission (AOGCC or Commission)
issued permits to drill the subject wells. 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 entity 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.aubert@alaska.r ov.

I'm writing in response to your September 30, 2009, letter wherein you requested a letter to verify suspended,
long-term shut-in and observation wells. 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

Re: Failure to Respond to Request for Information (20 AAC 25.300)
Status of Oil and Gas Wells
Dear Mr. Hagenson:
Under 20 AAC 25.300 you are required to provide information requested by the Alaska
Oil and Gas Conservation Commission (Commission). On January 28, 2009 the Commission
requested verification of suspended, long-term shut-in and observation wells. To date you have
provided no response to the Commission.
This correspondence constitutes the Commission's final request for you to verify the
wells as suspended, long-term shut-in or observation wells. If the requested information has not
been received by the Commission by the close of business on December 1, 2009, you will be
considered in violation of 20 AAC 25.300 and the Commission will take such action as it deems
appropriate including, but not limited to, initiation of a public hearing, initiation of an
enforcement action, and imposition of penalties as authorized under AS 31.05.150.
If you have any questions regarding this request, please contact Winton Aubert at

Thank you. Although we have no one on staff who was here during that time, it does appear with some of the
documents we uncovered that it was a division in Department of Commerce and not a part of AEA or old APA. Fred —
regardless of that issue, we can still help get this issue addressed.

I have our geothermal project manager looking into this and we have a call into Gwen at UAF. 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)?

Attached is a copy of a letter we received regarding DCCED well closure obligations from the Pilgrim Springs Geothermal
project from 1979-1982.
The operator is listed as DCCED Division of Energy and Power. Did that migrate into AEA, and can you help me run this

We need to come up with an abandonment plan or plan of suspension. We also likely need to apply for an

As operators or landowner of record, you are advised that the ten geothermal wells drilled in the
area of Pilgrim Springs, Alaska (see attached list) must either be plugged and abandoned in
compliance with 20 AAC 25.105 and 20 AAC 25.112 or suspended under 20 AAC 25.110. Alaska Oil
and Gas Conservation AOGCC regulations can be found at the following internet address:
llttp;fAdoa.a{aska,g¢y1Qgc%R_egulations/Reglndex.4tm1. A Sundry application form (Form 10-403)
for the submittal of a plan of abandonment or a plan of suspension for a well to the AOGCC can he
found at: tlttp:/jdoa,aaiaska.gov/ogc/formslforms.html. Please note that each application for
Sundry Approval must include a well schematic diagram showing the well's current condition and a
well schematic diagram showing proposed downhole well design changes to comply with
applicable regulations for plug and abandonment or suspension.
Pilgrim Springs Geothermal Wells
September 12, 2014
Page 2 of 2
If the AOGCC does not receive an acceptable plan and schedule for all ten wells within ninety (90)
days of receipt of this letter, the AOGCC will notice a public hearing to determine whether remedial
action is necessary with regard to the wells and which entity will bear responsibility for
compliance.
The applicable University of Alaska, Fairbanks Alaska Center for Energy & Power's (UAF) lease will
be expiring soon relative to the PS# 12-1, PS 12-2, PS 12-3 and PS 13-1 wells. Under 20 AAC
25.105, all permitted wells on a property must be properly abandoned before expiration of the
operator's rights. Upon expiration of the lease, if these wells are not plugged and abandoned to the
satisfaction of the AOGCC, UAF's bond will be forfeited. Forfeiture of the bond will not relieve UAF
of responsibility for plugging and abandoning of the welts under AS 31.05. If Unaatuq, LLC desires
to take over operatorship of these four wells, a Designation of Operator Form (Form 10 411) must
be submitted to and approved by the AOGCC, as provided under 20 AAC 25.020 in addition to Filing
the bond required by 20 AAC 25.025.

Subject: Pilgrim Hot Springs
Winton,
I would like to confirm that the work conducted through the Alaska Center for Energy and Power
(University of Alaska Fairbanks) at Pilgrim Hot Springs is purely intended for research
purposes. 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.

Pilgrim Spring Geothermal Drilling and Testing Program - Notes and Coordinates
for Wells
From: Steve Davies
A total of six exploratory geothermal wells have been drilled at Pilgrim Springs, located about 60 miles
north of Nome, Alaska. 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

Development, 62 p.

Center for Energy and Power.
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 Beverly 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.

MEMORANDUM TO FILE
From: Waylin Sieler
Date August 3, 2010
Subject: Pilgrim Hot Springs
Six wells located at Pilgrim Hot Springs were drilled without permits to drill. 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. The permit numbers allocated are as follows:

6-29-10 Preliminary Reconnaissance Trip Report
Pilgrim Hot Springs Geothermal Exploration
Prepared by: Peter Illig, Alaska Center for Energy and Power, University of Alaska Fairbanks
Goals
Our preliminary trip to Pilgrim H.S. was intended to locate, map, and determine the status of all 6 wells located
at Pilgrim Hot Springs, including those on adjoining MINC land, and to get a general feel for stable ground in the
area and potential challenges associated with ground-based surveys planned for later this summer.
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.

Pilgrim Hot Springs Wellhead Repair
Prepared by: Dan Brotherton, Arctic Drilling, Inc. & Markus Mager, ACEP
Overview
This task was completed in two phases, including:
1) an initial site visit in July 2010 to assess the condition of the six existing wells and develop a work plan
for replacing the wellhead assemblies as needed, and
2) a second trip to the site to complete the work outlined in the work plan. 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

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).

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).

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.

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.

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.

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.

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.

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).

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).

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

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.

replace valve before this well can be accessed with instruments.

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.

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.
