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.

Abstract: Systems for stimulation a formation include a plurality of variable frequency drives, each in communication with at least two high pressure pumps. A variable frequency drive actuates at least two electric motors associated with the high pressure pumps, such that the pumps pressurize fracturing fluid, proppant, or combinations thereof for flowing the fracturing fluid, proppant, or combinations thereof into the formation.

Abstract: Systems, units, 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, propylene carbonate, 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.

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.

Abstract: The present invention relates to servicing fluids for use in subterranean operations. More particularly, the present invention relates to improved servicing fluids comprising optimized hydrocarbon blends and methods of using such servicing fluids in subterranean formations. One embodiment of the preset invention provides a method of treating a subterranean formation comprising the steps of providing a servicing fluid comprising a hydrocarbon blend wherein the hydrocarbon blend comprises at least about 65% hydrocarbons having from 6 carbons (C6) to eleven carbons (C11); and placing the servicing fluid into the subterranean formation. Another embodiment of the present invention provides a subterranean servicing fluid comprising a hydrocarbon blend wherein the hydrocarbon blend comprises at least about 65% hydrocarbons having from 6 carbons (C6) to eleven carbons (C11).

Abstract: Improved methods and apparatus for completing an unconsolidated subterranean zone penetrated by a well bore are provided. The methods basically comprise the steps of placing a slotted liner having an internal sand screen disposed therein with dividers extending between the screen and liner, isolating the slotted liner and the well bore in the zone and injecting particulate material into flow paths formed by the dividers between the sand screen and the slotted liner and into the annulus between the slotted liner and the well bore to thereby form packs of particulate material therein to prevent the migration of fines and sand with produced fluids.
