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.
