Patent number: 10125592Abstract: Improved methods and systems for treating subterranean formations using a sub-surface mixing system are disclosed. The disclosed system includes a well head and a first flow line that directs a blender fluid from a blender to the well head. A second flow line directs a Liquefied Petroleum Gas stream to the well head. A static mixer is positioned downhole and is fluidically coupled to the well head. The well head directs the blender fluid to the static mixer through a first flow path and it directs the Liquefied Petroleum Gas stream from the well head to the static mixer through a second flow path. The static mixer then mixes the blender fluid and the Liquefied Petroleum Gas stream.Type: GrantFiled: August 8, 2013Date of Patent: November 13, 2018Assignee: Halliburton Energy Services, Inc.Inventors: Leonard R. Case, Jason E. Bryant, Loyd Eddie East

Patent number: 8834012Abstract: 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.Type: GrantFiled: May 6, 2010Date of Patent: September 16, 2014Assignee: Halliburton Energy Services, Inc.Inventors: Leonard R. Case, Ed B. Hagan, Calvin L. Stegemoeller, Ron Hyden

Patent number: 8727004Abstract: 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.Type: GrantFiled: June 1, 2009Date of Patent: May 20, 2014Assignee: Halliburton Energy Services, Inc.Inventors: Brad R.
