- the freeze wells are placed in the formation so that the low temperature zones overlap and form a low temperature zone around the treatment area.
- the low temperature zone established by freeze wells is maintained below the freezing temperature of aqueous fluid in the formation.
- Aqueous fluid entering the low temperature zone freezes and forms the frozen barrier.
- the freeze barrier is formed by batch operated freeze wells.
- a cold fluid, such as liquid nitrogen, is introduced into the freeze wells to form low temperature zones around the freeze wells. The fluid is replenished as needed.

The thick barrier may ensure that breakthrough of the frozen barrier established by the freeze wells does not occur.
- Horizontally positioned freeze wells and/or horizontally positioned freeze wells may be positioned around sides of the treatment area. If the upper layer (the overburden) or the lower layer (the underburden) of the formation is likely to allow fluid flow into the treatment area or out of the treatment area, horizontally positioned freeze wells may be used to form an upper and/or a lower barrier for the treatment area. In some embodiments, an upper barrier and/or a lower barrier may not be necessary if the upper layer and/or the lower layer are at least substantially impermeable.
- portions of heat sources, production wells, injection wells, and/or dewatering wells that pass through the low temperature zone created by the freeze wells forming the upper freeze barrier wells may be insulated and/or heat traced so that the low temperature zone does not adversely affect the functioning of the heat sources, production wells, injection wells and/or dewatering wells passing through the low temperature zone.
- Spacing between adjacent freeze wells maybe a function of a number of different factors. The factors may include, but are not limited to, physical properties of formation material, type of refrigeration system, coldness and thermal properties of the refrigerant, flow rate of material into or out of the treatment area, time for forming the low temperature zone, and economic considerations. Consolidated or partially consolidated formation material may allow for ⁇ a large separation distance Between freeze wells. A separation distance between freeze wells in consolidated or partially consolidated formation material may be from 3 m to 20 m, 4 m to 15 m, or 5 m to 10 m. In an embodiment, the spacing between adjacent freeze wells is 5 m. Spacing between freeze wells in unconsolidated or substantially unconsolidated formation material, such as in tar sand, may need to be smaller than spacing in consolidated formation material. A separation distance between freeze wells in unconsolidated material may be from 1 m to 5 m.
- Freeze wells may be placed in the formation so that there is minimal deviation in orientation of one freeze well relative to an adjacent freeze well. Excessive deviation may create a large separation distance between adjacent freeze wells that may not permit formation of an interconnected low temperature zone between the adjacent freeze wells.

- Spacers 120 may position inlet conduit 118 in canister 116 so that an annular space is formed between the canister and the conduit. Spacers 120 may promote turbulent flow of refrigerant in the annular space between inlet conduit 118 and canister 116, but the spacers may also cause a significant fluid pressure drop. Turbulent fluid flow in the annular space may be promoted by roughening the inner surface of canister 116, by roughening the outer surface of inlet conduit 118, and/or by having a small cross-sectional area annular space that allows for high refrigerant velocity in the annular space.

- Protective sleeve 136 may be stainless steel tubing or other tubing.
- Various types of refrigeration systems may be used to form a low temperature zone. Determination of an appropriate refrigeration system may be based on many factors, including, but not limited to: type of freeze well; a distance between adjacent freeze wells; refrigerant; time frame in which to form a low temperature zone; depth of the low temperature zone; temperature differential to which the refrigerant will be subjected; chemical and physical properties of the refrigerant; environmental concerns related to potential refrigerant releases, leaks, or spills; economics; formation water flow in the formation; composition and properties of formation water, including the salinity of the formation water; and various properties of the formation such as thermal conductivity, thermal diffusivity, and heat capacity.

- Dynalene ® HC-50 Dynalene ® Heat Transfer ⁇ lu ⁇ cls (W ⁇ teiiaU ' KimsylvaniaJ ' ⁇ .S ' .A.)) or FREEZIUM ® (Kemira Chemicals (Helsinki, Finland)
- Aqua ammonia is a solution of ammonia and water with a weight percent of ammonia between 20% and 40%. Aqua ammonia has several properties and characteristics that make use of aqua ammonia as the formation refrigerant desirable. Such properties and characteristics include, but are not limited to, a very low freezing point, a low viscosity, ready availability, and low cost.
- Formation refrigerant that is capable of being chilled below a freezing temperature of aqueous formation fluid may be used to form the low temperature zone around the treatment area.
- the following equation (the Sanger equation) may be used to model the time /; needed to form a frozen barrier of radius -R around a freeze well having a surface temperature of T/.
- Ay- is the thermal conductivity of the frozen material
- c v y and c m are the volumetric heat capacity of the frozen and unfrozen material, respectively
- r 0 is the radius of the freeze well
- v s is the temperature difference between the freeze well surface temperature T s and the freezing point of water T 0
- v o is the temperature difference between the ambient ground temperature T g and the freezing point of water T 0
- L is the volumetric latent heat of freezing of the formation
- R is the radius at the frozen-unfrozen interface
- R A is a radius at which there is no influence from the refrigeration pipe.

- the temperature of the formation refrigerant is an adjustable variable that may significantly affect the spacing between freeze wells.
- EQN. 1 implies that a large low temperature zone may be formed by using a refrigerant having an initial temperature that is very low.
- the use of formation refrigerant having an initial cold temperature of -30 0 C or lower is desirable.
- Formation refrigerants having initial temperatures warmer than -30 0 C may also be used, but such formation refrigerants require longer times for the low temperature zones produced by individual freeze wells to connect.
- such formation refrigerants may require the use of closer freeze well spacings and/or more freeze wells.
- the physical properties of the material used to construct the freeze wells may be a factor in the determination of the coldest temperature of the formation refrigerant used to form the low temperature zone around the treatment area.
- Carbon steel may be used as a construction material of freeze wells.
- ASTM A333 grade 6 steel alloys and ASTM A333 grade 3 steel alloys may be used for low temperature applications.
- ASTM A333 grade 6 steel alloys typically contain little or no nickel and have a low working temperature limit of -50 0 C.
- ASTM A333 grade 3 steel alloys typically contain nickel and have a much colder low working temperature limit. The nickel in the ASTM A333 grade 3 alloy adds ductility at cold temperatures, but also significantly raises the cost of the metal.
- the coldest temperature of the refrigerant is from -35 0 C to -55 0 C, from -38 0 C to -47 0 C, or from -40 0 C to -45 °C to allow for the use of ASTM A333 grade 6 steel alloys for construction of canisters for freeze wells.
- Stainless steels such as 304 stainless steel, may be used to form freeze wells, but the cost of stainless steel is typically much more than the cost of ASTM A333 grade 6 steel alloy.
- the metal used to form the canisters of the freeze wells may be provided as pipe. In some embodiments, the metal used to form the canisters of the freeze wells may be provided in sheet form.
- the sheet metal may be longitudinally welded to form pipe and/or coiled tubing. Forming the canisters from sheet metal may improve the economics of the system by allowing for coiled tubing insulation and by reducing the equipment and manpower needed to form and install the canisters using pipe.
- a refrigeration unit may be used to reduce the temperature of formation refrigerant to the low working temperature. In some embodiments, the refrigeration unit may utilize an ammonia vaporization cycle. Refrigeration units are available from Cool Man Inc. (Milwaukee, Wisconsin, U.S.A.), Gartner Refrigeration & Manufacturing (Minneapolis, Minnesota, U.S.A.), and other suppliers.
- a cascading refrigeration system may be utilized with a first stage of ammonia and a second stage of carbon dioxide.
- the circulating refrigerant through the freeze wells may be 30% by weight ammonia in water (aqua ammonia).
- a single stage carbon dioxide refrigeration system may be used.
- a temperature monitoring system may be installed in wellbores of freeze wells and/or in monitor wells adjacent to the freeze wells to monitor the temperature profile of the freeze wells and/or the low temperature zone established by the freeze wells.
- the monitoring system may be used to monitor progress of low temperature zone formation.
- the monitoring system may be used to determine the location of high temperature areas, potential breakthrough locations, or breakthrough locations after the low temperature zone has formed.
- Periodic monitoring of the temperature profile of the freeze wells and/or low temperature zone established by the freeze wells may allow additional cooling to be provided to potential trouble areas before breakthrough occurs. Additional cooling may be provided at or adjacent to breakthroughs and high temperature areas to ensure the integrity of the low temperature zone around the treatment area.
- Additional cooling may be provided by increasing refrigerant flow through selected freeze wells, installing an additional freeze well or freeze wells, and/or by providing a cryogenic fluid, such as liquid nitrogen, to the high temperature areas.
- Providing additional cooling to potential problem areas before breakthrough occurs may be more time efficient and cost efficient than sealing a breach, reheating a portion of the treatment area that has been cooled by influx of fluid, and/or remediating an area outside of the breached frozen barrier.
- a traveling thermocouple may be used to monitor the temperature profile of selected freeze wells or monitor wells.
- the temperature monitoring system includes thermocouples placed at discrete locations in the wellbores of the freeze wells, in the freeze wells, and/or in the monitoring wells.
- the temperature monitoring system comprises a fiber optic temperature monitoring system.
- Fiber optic temperature monitoring systems are available from Sensornet (London, United Kingdom), Sensa (Houston, Texas, U.S.A.), Luna Energy (Blacksburg, Virginia, U.S.A.), Lios Technology GMBH (Cologne, Germany), Oxford Electronics Ltd. (Hampshire, United Kingdom), and Sabeus Sensor Systems (Calabasas, California, U.S.A.).
- the fiber optic temperature monitoring system includes a data system and one or more fiber optic cables.
- the data system includes one or more lasers for sending light to the fiber optic cable; and one or more computers, software and peripherals for receiving, analyzing, and outputting data.
- the data system may be coupled to one or more fiber optic cables.
- a ' single Tiber optic cable may ' be several kilometers long.
- the fiber optic cable may be installed in many freeze wells and/or monitor wells.
- two fiber optic cables may be installed in each freeze well and/or monitor well.
- the two fiber optic cables may be coupled together. Using two fiber optic cables per well allows for compensation due to optical losses that occur in the wells and allows for better accuracy of measured temperature profiles.
- a fiber of a fiber optic cable may be placed in a polymer tube.
- the polymer tube may be filled with a heat transfer fluid.
- the heat transfer fluid may be a gel or liquid that does not freeze at or above the temperature of formation refrigerant used to cool the formation.
- the heat transfer fluid in the polymer tube is the same as the formation refrigerant, for example, a fluid available from Dynalene ® Heat Transfer Fluids or aqua ammonia.
- the fiber is blown into the tube using the heat transfer fluid. Using the heat transfer fluid to insert the fiber into the polymer tube removes moisture from the polymer tube.
- the polymer tube and fiber may be placed in the protective sleeve, such as 1 A inch 304 stainless steel tubing, to form the fiber optic cable.
- the protective sleeve may be prestressed to accommodate thermal contraction at low temperatures.
- the protective sleeve may be filled with the heat transfer fluid.
- the polymer tube is blown into the protective sleeve with the heat transfer fluid. Using the heat transfer fluid to insert the polymer tube and fiber into the protective sleeve removes moisture from the protective sleeve.
- two fibers are positioned in the same stainless steel tube.
- the fiber is placed directly in the protective sleeve without being placed in a polymer tube.
- the fiber optic cable is strapped to the canister of the freeze well as the canister is inserted into the formation.
- the fiber optic cable may be coiled around the canister adjacent to the portions of the formation that are to be reduced to low temperature to form the low temperature zone. Coiling the fiber optic cable around the canister allows a long length of the fiber optic cable to be adjacent to areas that are to be reduced to low temperature. The long length allows for better resolution of the temperature profile for the areas to be reduced to low temperatures.
- the fiber optic cable is placed in the canister of the freeze well.
- FIG. 4 depicts a schematic representation of a fiber optic temperature monitoring system.
- Data system 140 includes laser 142 and analyzer 144. Laser 142 injects short, intense light pulses into fiber optic cable 146.
- Fiber optic cable 146 is positioned in a plurality of freeze wells 114 and monitor wells 148.
- Fiber optic cable 146 may be strapped to the canisters of the freeze wells as the canisters are installed in the formation.
- the fiber optic cable is strapped to supports and inserted into the monitor wells.
- the protective sleeve of the fiber optic cable may be suspended in the monitor wells without an additional support.
- Backscattering and reflection of light in fiber optic cable 146 may be measured as a function of time by analyzer 144 of the data system 140. Analysis of the backscattering and reflection of light data yields a temperature profile along the length of fiber optic cable 146.
- the data system is a double ended system.
- the data system may include one or more lasers that send light pulses into each end of the fiber optic cable.
- the laser includes one laser. The laser sends pulses to each end of the fiber optic cable in an alternating manner. The return signals received by the data system allows for compensation of signal attenuation in the optical fiber.
- computer control system 150 is in communication with the fiber optic temperature monitoring system and the formation refrigeration circulation system.
- the formation refrigeration circulation system may include refrigeration system 152.
- Refrigeration system 152 sends chilled formation refrigerant to wellheads 124 of freeze wells 114 through piping 154.
- the formation refrigerant passes down the inlet conduit of the freeze well and up through the annular space between the inlet conduit and the freeze well canister. The formation refrigerant then passes through the piping to the next freeze well.
- Computer control system 150 may allow for automatic monitoring of the low temperature zone established by freeze wells 114.
- Computer control system 150 may periodically shut down the flow of formation refrigerant to a set of freeze wells for a given time. For example, computer control system 150 may shut down the flow of formation refrigerant to a specific set of freeze wells every 60 days for a period of two days and activate data system 140 to monitor the temperature profile near the shut down freeze wells. The temperature profile of the freeze wells with no formation refrigerant flow will begin to rise.
- Computer control system 150 may monitor the rate of increase of temperature. If there is a problem area, the temperature profile near the problem area will show a greater rate of change than the temperature profile of adjacent areas. If a larger than expected temperature increase occurs at approximately the same depth location at or near two adjacent wells, the computer control system may signal that there is a problem to an operator of the system. The location of the problem area may be estimated/modeled/assessed by comparing the temperature increases between adjacent wells. For example, if the temperature increase in a first well is twice as large as the temperature increase in a second well, then the location of the problem area may be closer to the first well. Extra cooling and/or extra monitoring can be provided to problem areas.
- Extra cooling may be provided by increasing the flow of formation refrigerant to the problem area and/or by installing one or more additional freeze wells. If no problems are detected during the given time, the computer system restarts the flow of formation fluid to the specific set of freeze wells and begins a test of another set of freeze wells. Using computer control system 150 to monitor the low temperature zone established by freeze wells allows for problems to be detected and fixed before a breach of the barrier formed by the freeze wells occurs.
- the fiber optic temperature monitoring system utilizes Brillouin or Raman scattering systems. Such systems provide spatial resolution of 1 m and temperature resolution of 0.1 0 C. With sufficient averaging and temperature calibration, the systems may be accurate to 0.5 °C.
- the fiber optic temperature monitoring system may be a Bragg system that uses a fiber optic cable etched with closely spaced Bragg gratings. The Bragg gratings may be formed in 1 foot increments along selected lengths of the fiber. Fibers with Bragg gratings are available from Luna Energy. The Bragg system only requires a single fiber optic cable to be placed in each well that is to be monitored. The Bragg system is able to measure the fiber temperature in a few seconds.
- the fiber optic temperature monitoring system may be used to detect the location of a breach or a potential breach in a frozen barrier.
- the search for potential breaches may be performed at scheduled intervals, for example, every two or three months.
- flow of formation refrigerant to the freeze wells of interest is stopped.
- the flow of formation refrigerant to all of the freeze wells is stopped.
- the rise in the temperature profiles, as well as the rate of change of the temperature profiles, provided by the fiber optic temperature monitoring system for each freeze well can be used to determine the location of any breaches or hot spots in the low temperature zone maintained by the freeze wells.
- the temperature profile monitored by the fiber optic temperature monitoring system for the two freeze wells closest to the hot spot or fluid flow will show the quickest and greatest rise in temperature.
- a temperature change of a few degrees Centigrade in the temperature profiles of the freeze wells closest to a troubled area may be sufficient to isolate the location of the trouble area.
- the shut down time of flow of circulation fluid in the freeze wells of interest needed to detect breaches, ' potentiaT ' breachesj and ' h ' ot " spots may be on the order of a few hours or days, depending on the well spacing and the amount of fluid flow affecting the low temperature zone.
- Fiber optic temperature monitoring systems may also be used to monitor temperatures in heated portions of the formation during in situ conversion processes.
- the fiber of a fiber optic cable used in the heated portion of the formation may be clad with a reflective material to facilitate retention of a signal or signals transmitted down the fiber.
- the fiber is clad with gold, copper, nickel, aluminum and/or alloys thereof.
- the cladding maybe formed of a material that is able to withstand chemical and temperature conditions in the heated portion of the formation. For example, gold cladding may allow an optical sensor to be used up to temperatures of 700 0 C.
- the fiber is clad with aluminum. The fiber may be dipped in or run through a bath of liquid aluminum. The clad fiber may then be allowed to cool to secure the aluminum to the fiber.
- the gold or aluminum cladding may reduce hydrogen darkening of the optical fiber.
