20100270023 | Methods and Compositions for Packing Void Spaces and Stabilizing Formations Surrounding a Wellbore - Methods are provided that include a method comprising mixing particulates with a consolidating agent emulsion to form a slurry; creating a foamed slurry by adding a foaming agent and a gas to the slurry; placing the foamed slurry into a portion of a subterranean formation so as to create a particulate pack; and flushing the particulate pack with a postflush fluid. In some embodiments, the consolidating agent emulsion composition comprises a resin composition. Additional methods are also provided. | 10-28-2010 |
20120006551 | Compositions and Methods of Treating High Temperature Subterranean Formations - Well treatment fluids and methods of treating high temperature subterranean formations of up to about 500° F. (260° C.) are provided. The well treatment fluids and methods utilize a high molecular weight synthetic copolymer and a pH buffer than maintains a pH in a range of about 4.5 to about 5.25 for the fluids. The high molecular weight synthetic copolymer is derived from acrylamide, acrylamidomethylpropanesulfonic acid, and vinyl phosphonates. The well treatment fluids may be energized or foamed. | 01-12-2012 |
20130025869 | Thermally Stable, Nonionic Foaming Agent for Foam Fracturing Fluids - A method foamed fracturing may include providing a wellbore that extends into a subterranean formation and introducing a foamed fracturing fluid into the subterranean formation at a pressure sufficient to create or enhance at least one fracture in at least a portion of the subterranean formation. The foamed fracturing fluid may generally include an aqueous base fluid, a sugar derivative foaming agent, and a gas. | 01-31-2013 |
20130098622 | DOWNHOLE POLYMER FOAM APPLICATIONS - A method of treating a subterranean formation penetrated by a wellbore by contacting an energized fluid with the subterranean formation; and reducing a partial pressure of the energized fluid by an amount sufficient to form polymeric foam structure within the subterranean formation | 04-25-2013 |
20130327531 | Viscoelastic Surfactant Fluids and Related Methods of Use - Viscoelastic surfactant based aqueous fluid systems useful as thickening agents in various applications, e.g. to suspend particles produced during the excavation of geologic formations. The surfactants are zwitterionic/amphoteric surfactants such as dihydroxyl alkyl glycinate, alkyl ampho acetate or propionate, alkyl betaine, alkyl amidopropyl betaine and alkylimino mono- or di-propionates derived from certain waxes, fats and oils. The thickening agent is used in conjunction with an inorganic water-soluble salt or organic additive such as phthalic acid, salicylic acid or their salts. | 12-12-2013 |
20140008074 | Fracturing System and Method for an Underground Formation - A method for fracturing a downhole formation, includes: preparing an energized fracturing fluid including mixing gaseous natural gas and a fracturing base fluid in a mixer; injecting the energized fracturing fluid through a wellhead and into a well; and continuing to inject the energized fracturing fluid until the formation is fractured. An apparatus for generating an energized fracturing fluid for use to fracture a downhole formation, the apparatus includes: a fracturing base fluid source; a natural gas source; and a mixer for accepting natural gas from the natural gas source and fracturing base fluid from the fracturing base fluid source and mixing the natural gas and the fracturing base fluid to generate the energized fracturing fluid. | 01-09-2014 |
20160075932 | Foamed Fluid Compositions Having High Salinity Using Anionic Surfactants and Methods Therefor - An effective amount of at least one anionic surfactant may be present within a high salinity foamed fluid composition in an effective amount to generate an IFT as low as 10 | 03-17-2016 |
