  • Patent number: 9850422
    Abstract: Systems, compositions, and methods usable to stimulate a formation include a first supply subsystem adapted to provide a first medium to the formation and a pressure subsystem that includes a pump in communication with the first medium to pressurize the first medium to a pressure sufficient to stimulate the formation. Usable media can include non-gelled liquid alkanes, halogenated hydrocarbons, foamed hydrocarbons, a fluidized solid proppant material that behaves as a liquid under threshold conditions, or a liquid material adapted to solidify under threshold conditions. A proppant can be supplied in addition to the first medium when performing fracturing operations. Usable proppant can include materials having a size or density adapted to facilitate buoyancy, hollow materials, composite materials, porous materials, or crystalline materials.

  • Publication number: 20160281484
    Abstract: Systems for stimulation of a formation include a variable frequency drive configured to receive and output medium voltage power and in communication with high pressure pump. A variable frequency drive actuates an electric motor associated with the high pressure pump, such that the pumps pressurizes a fracturing fluid, proppant, or combinations thereof for flowing the fracturing fluid, proppant, or combinations thereof into the formation.

  • Publication number: 20080006410
    Abstract: The present invention is directed to methods for extracting a kerogen-based product from subsurface (oil) shale formations, wherein such methods rely on fracturing and/or rubblizing portions of said formations so as to enhance their fluid permeability, and wherein such methods further rely on chemically modifying the shale-bound kerogen so as to render it mobile. The present invention is also directed at systems for implementing at least some of the foregoing methods. Additionally, the present invention is also directed to methods of fracturing and/or rubblizing subsurface shale formations and to methods of chemically modifying kerogen in situ so as to render it mobile.

  • Publication number: 20050189112
    Abstract: The present invention relates to gelled fluids and methods for using liquefied petroleum gas in subterranean operations. More particularly, the present invention relates to servicing fluids that comprise gelled liquefied petroleum gas or servicing fluids that comprise a conventional gelled hydrocarbon fluid with liquefied petroleum gas and methods of using such servicing fluids in subterranean formations. One embodiment of the present invention provides a method of treating a subterranean formation comprising the steps of providing a gelled LPG fluid comprising liquefied petroleum gas and a gelling agent; and placing the gelled LPG fluid into the subterranean formation. Another embodiment of the present invention provides a method of treating a subterranean formation comprising the steps of providing a combined LPG servicing fluid comprising liquefied petroleum gas and a conventional hydrocarbon servicing fluid; and placing the combined LPG servicing fluid into the subterranean formation.
