Description
TELESCOPIC FRAC WATER TANK
Field of the Invention [0001] The invention relates to water tanks for use in frac operations, and more particularly large volume, transportable, steel water tanks with integrated secondary containment and pumping system compatibility.
Background of the Invention
Field of the Invention [0001] The invention relates to water tanks for use in frac operations, and more particularly large volume, transportable, steel water tanks with integrated secondary containment and pumping system compatibility.
Background of the Invention
[0002] Large volumes of water are required for hydraulic stimulation (referred to as fracture) of wellsites. In order to store large volumes of water, either many traditional horizontal rectangular tanks, or many traditional vertical cylindrical tanks, are needed, often in conjunction with a geomembrane lined open top tank (which is prone to damage and leaks).
[0003] Open top tanks are large volume tanks with a large surface footprint.
They are usually circular, which is an inefficient use of space. Using open top tanks requires transferring fluid from the tank to a frac tank farm for use by the frac equipment. Open top tanks are lined with a geomembrane liner that is fragile and prone to damage and leaks. The liner is not reusable, and is expensive to replace. Specialized pumping equipment is required to use with these tanks. It is difficult to safely get all of the fluid in a tank from the tank bottom, resulting in some waste.
Open top tanks are expensive to clean and decommission, and can cause a major incident in the case of tank failure, as there is no secondary containment. These tanks are not compartmentalized and in case of a failure, the entire volume of water may be lost. There are also limits on the height of these tanks, resulting in large footprints as the capacity per area of land is low

There are also limits on the height of these tanks, resulting in large footprints as the capacity per area of land is low
[0004] Vertical cylindrical 400bbl tanks are a standard oilfield tank, widely used in Canada.
Volume is normally 400bbl, or 60m3 capacity. At best, they can be transported in pairs on one truck. The cylindrical tanks require elaborate manifolds and many hoses to properly connect the tanks for frac use. As the tanks have no built in containment, the tank farm is typically bermed and lined. Matting is required underneath the tanks. Matting and manifolds and hoses typically require at least one full additional truck load. The cylindrical tanks also take up a large footprint on an area/volume basis.

Matting is required underneath the tanks. Matting and manifolds and hoses typically require at least one full additional truck load. The cylindrical tanks also take up a large footprint on an area/volume basis.
[0005] Rectangular Tanks are either mobile with an axle, or skidded, and are widely used in the U.S. These rectangular may have volumes up to 100m3, although 80m3 is more common. These tanks have all the disadvantages of the vertical tanks, and require an even larger surface footprint. In addition, they can only be transported or moved as single tanks, which adds to the transportation and set up cost.
[0006] What the current tanks used in frac operations lack are having built in secondary containment, and integrated or compatible pumping systems, and a tank design that is easily transportable but also high volume.
Summary of the Invention
Summary of the Invention
[0007] The telescopic frac water tanks according to the invention provide large volume fluid storage, a compact footprint, with minimal transportation and installation cost. The system combines three components, namely a large volume horizontal telescopic tank that is highway transportable; easily integrated pumping systems; and built in secondary containment
[0008] The tank according to the invention is used to support the hydraulic stimulation (fracture) of shale gas wells. A pad operation for such frac operations likely includes at least three of these tanks, each having a volume of at least 500m3. A first tank serves as a primary storage/receiving tank, and supplies fluid to a second tank. The second tank is used in place of the traditional frac tank farm and suction manifold, and the frac equipment blender and charge pumps are tied directly into the second tank. The third tank is used for flowback storage and transfer, replacing the traditional flowback tank farm.
[0009] Large volume storage is thereby realized via one transportable tank according to the invention. The tank is adjustable in height once delivered to the location, to allow for large volume capability.
Setup and installation of the tank is fast, resulting in significant transportation cost savings. The incorporated containment prevents environmental spills, and the included recirculation pump transfers fluid from containment back into the tank, if necessary.
The incorporated pumping systems and tank connections further increase functionality, and eliminate the need for additional equipment. Each tank can replace up to 8 standard vertical tanks, or 6 standard horizontal tanks.

[0010] A system using the tanks according to the invention is capable of transferring high volumes of water to the frac equipment, pumping at high pressure off the pad to offsite storage, and receiving and transferring flowback water to the primary pad storage tank.
In addition, pumping systems allow for fluid circulation to prevent line freeze problems, as well as circulation through a water heater. Incorporated light masts can eliminate additional surface rentals, such as light towers, and incorporated weirs allow compartment separation and can be used for sand settling, chemical injection, and other functions.

Figures 5A through 5D each represent an alternative sealing means. Additional sealing is provided by grease injection and gasket material 55 between inner tank wall 40 and exterior wall 60. Grease injection nipples 45 may be positioned at regular intervals to allow grease injection.
[0025] As seen in Figure 5A, projection 100 at the bottom and outside of interior tank wall 40, is sized to fit indentation 110 at the top and inside of exterior wall 60. Gasket material 55 is positioned between projection 100 and indentation 110.
[0026] An alternative embodiment is shown in Figure 5B, in which mating projection 120 at the bottom outside edge of interior tank wall 40 meets mating projection 130 at the top inside edge of exterior tank wall 60. Gasket material 55 is positioned between projections 120, 130.
[0027] Figure 5C shows another embodiment of a seal, wherein dividers 140 at the bottom of inner tank wall 40 from channels 150. Inflatable rubber hoses 160 run through each channel 150, and are inflated when the inner tank wall 40 is raised. Between each rubber hose 160 and exterior wall 60 are rubber sealing gaskets 170.
[0028] Figure 5D shows yet a further embodiment of a seal, in which gasket 55 on pivotable member 180, is positionable under inner tank wall 40, after inner tank wall 40 has been raised.
Inner tank wall 40 then seals by using gravity as inner tank wall 40 rests on pivotable member 180 which pivots on hinge 185.
Inner tank wall 40 then seals by using gravity as inner tank wall 40 rests on pivotable member 180 which pivots on hinge 185.
[0029] Containment tray 70 is positioned around the base 80 of exterior tank wall 60 to contain any leakage that may slip through the seals at the junction of interior tank wall 40 and exterior wall 60. A built in transfer pump (not shown) may be present to transfer any fluid collected in the containment tray back into the main tank 10.
[0030] Exterior wall 60 includes a plurality of flanged and valved connection ports (not shown) to allow for fluid transfer and reception.
[0031] Figure 6 shows an alternative embodiment of the invention in which outer wall 200 is raise by hydraulic rams 50 relative to inner wall 210. An example of a sealing mechanism for this embodiment is shown in Figure 7, in which inward extension 220 at the bottom of outer wall 200 meets outer facing extension 230 of inner wall 210. Rubber inflatable seal members 240, as shown in Figure 8, may be positioned on either inward extension 220 or outward extension 230 facing the other extension. When the rubber seal meets, they flatten, and may be inflated, creating a seal between inner wall 210 and outer wall 200.
[0032] Tank floor 90 may be gently sloped and have a fluid outlet at the base 80 to allow for ease of extraction of the fluid. Built in pumping systems (not shown) may be present to allow transfer of fluid between tanks 10, transfer of fluid off site, and circulation of fluid through heaters and pipelines to prevent freezing. Alternatively, the pumping systems may be positioned nearby, and in fluid communication with tank 10 via hoses and the like.
[0033] When frac job is finished, the tank 10 is drained, inner (or outer) tank wall 40 is lowered to transport height, tank 10 is winched onto standard high-bed tractor trailer, and can be moved from the site. Typical volume of tank 10 would be 500m3, based on a two tier tank wall design.
