Reservoir Tube Heater
This invention pertains to an apparatus to efficiently provide a means to heat liquid in the oil and gas fields, specifically fracking operations. The apparatus described herein provides reservoir heaters connected via reservoir transfer tubes and a heat source, located at the bottom of the apparatus, which thoroughly heats liquid as the liquid travels from the bottom of the apparatus to the top of the apparatus.
The invention pertains to the field of providing hot liquid, particularly water for field application in the oil and gas industry. The apparatus comprises a means for effectively and inexpensively providing heated liquid on demand through a novel heating apparatus. Use of the apparatus provides significant quantity of heated water at a fraction of the heating costs currently contemplated for field use.
BACKGROUND OF THE INVENTIONThe oil and gas industry began fracturing rock deposits, i.e., fracking, in approximately 1970. Since that time fracking has developed into the preferred method of gas exploration and recovery.
Liquid, typically heated water, is used in fracking operations. To accomplish fracking, heated liquid is applied or injected into formations. A constant and inexpensive supply of liquid is needed to maintain operations. Current and conventional technology employs a heater coil and boiler design, usually used to heat liquid and has been used in oil and gas field applications from 1950 to current. Again, the liquid most typically used is water.
There is a need for a means to provide significant amounts of heated liquid, typically water, in the oil and gas field. The conventional, current means of providing heated water are often expensive, unreliable, and require multiple apparatuses.
Thus, there is a long felt need for a system or method to effectively and inexpensively provided heated liquid, particularly water, for fracking operations in oil and gas fields.
SUMMARY OF THE INVENTIONAccordingly, it is an object of embodiments of the present invention to provide a means to provide an inexpensive and effective means to heat liquid, including water in remote gas and petroleum fields. The invention, which relates to a reservoir tube heater which flows liquid, typically water, through a series of reservoirs and liquid transfer tubes with a heat source, typically propane burners underneath. Liquid flows through the reservoir tube heater from the lower portion to the upper portion, contrary to current liquid heating systems currently used in the industry.
The present invention is concerned with a new and novel means to supply heated liquid for fracking and other oil and gas filed needs. To achieve the foregoing and other objects, and in accordance with the purposes of the present invention, as embodied and broadly described herein, comprises a reservoir-tube heater apparatus comprising horizontally stacked rows of liquid transfer tubes separating a first column of horizontally layered reservoirs and an opposing second column of horizontally layered reservoirs, said horizontally stacked rows of liquid transfer tubes having a bottom row of liquid transfer tubes, a top row of liquid transfer tubes and multiple rows of liquid transfer tubes therebetween, said first column of reservoirs comprising first reservoir having an opening intake orifice and a row of multiple outlet orifices connected to the bottom row of liquid transfer tubes, a last reservoir having an exit outtake orifice and a row of inlet orifices connected to the top row of liquid transfer tubes, said bottom row of liquid transfer tubes and said top row of liquid transfer tubes connected to multiple reservoir pairs comprised of a bottom reservoir having liquid inlet orifices, a top reservoir having liquid outlet orifices and reservoir transfer tube between the top and bottom reservoirs.
Additional objects, advantages and novel features of the invention will be set forth in part in the description which follows, and in part will become apparent to those skilled in the art upon examination of the following or may be learned by practice of the invention. The objects and advantages of the invention may be realized and attained by means of the instrumentalities and combinations particularly pointed out in the appended claims.
Benefits and advantages of the present invention include, but are not limited to, providing a system, which provides a means to effectively provide heated liquid at a fraction of the energy costs to the oil and gas industry. The invention is easy to use and can function in a variety of terrains without being cost prohibitive.

The flow of the liquid from the bottom of the reservoir tube heater apparatus allows the initial liquid flowing into the apparatus to be heated most at first. As the liquid continues to flow up through the multiplicity of horizontally layered reservoirs and horizontally stacked rows of liquid transfer tubes, the liquid continues to be heated because the heat from the heat source rises. Thus, the design of the instant invention allows for energy conservation and optimization to effectively heat with much less energy than is currently used to heat water in fracking operations. As discussed throughout this application the work liquid is most often to include water, which is most often used in fracking applications.
