Abstract: Methods and systems for integral storage and blending of the materials used in oilfield operations are disclosed. A modular integrated material blending and storage system includes a first module comprising a storage unit, a second module comprising a liquid additive storage unit and a pump for maintaining pressure at an outlet of the liquid additive storage unit. The system further includes a third module comprising a pre-gel blender. An output of each of the first module, the second module and the third module is located above a blender and gravity directs the contents of the first module, the second module and the third module to the blender. The system also includes a pump that directs the output of the blender to a desired down hole location. The pump may be powered by natural gas or electricity.

Abstract: Methods relating to servicing fluids that comprise gelled liquefied petroleum gas or servicing fluids that comprise a conventional gelled hydrocarbon fluid with liquefied petroleum gas are provided. In one embodiment, the methods of the present invention comprise providing a LPG servicing fluid comprising LPG and a gelling agent; pressurizing the LPG servicing fluid with one or more high-pressure pumps; introducing proppant particulates into at least a portion of the LPG servicing fluid using one or more high pressure pumps; and introducing the LPG servicing fluid comprising proppant particulates into at least a portion of a subterranean formation at a rate and pressure sufficient to create or enhance at least one or more fractures therein. In one embodiment, a gelling agent may be metered into the LPG on-the-fly.

Abstract: Methods and systems for integral storage and blending of the materials used in oilfield operations are disclosed. An integrated material blending and storage system is disclosed with a storage unit, a blender located under the storage unit, a liquid additive storage module having a pump to maintain constant pressure at an outlet of the liquid additive storage module and a pre gel blender. Gravity directs a first input from the storage unit, a second input from the liquid additive storage module and a third input from the pre-gel blender to the blender.

Abstract: A method is provided for treating at least a portion of a well. The method includes the steps of: (a) simultaneously introducing into a mixer at least: (i) a first stream comprising water; (ii) a second stream comprising a dry, hydratable, viscosity-increasing agent for water, wherein the second stream is substantially free of water; and (iii) a third stream comprising a non-hydratable, insoluble particulate; wherein at least the first and second streams are not mixed prior to being introduced into the mixer; (b) mixing the first, second, and third streams in the mixer to form a pumpable mixture, wherein: (i) the mixer creates at least a sufficiently-high shear rate to disperse the viscosity-increasing agent and the insoluble particulate in the pumpable mixture; and (ii) the pumpable mixture has or is capable of developing a substantially-higher viscosity than the viscosity of the first stream; and (c) introducing a treatment fluid comprising the pumpable mixture into a wellbore.

Abstract: Methods and systems for integrally processing the materials used in oilfield operations are disclosed. An integrated material processing system is disclosed with a storage unit resting on a leg. A feeder couples the storage unit to a first input of a mixer and a pump is coupled to a second input of the mixer. The storage unit contains a solid component of a well treatment fluid. The feeder supplies the solid component of the well treatment fluid to the mixer and the pump supplies a fluid component of the well treatment fluid to the mixer. The components are mixed in the mixer and the mixer outputs a well treatment fluid.
