One embodiment of the present invention provides a method of inhibiting metal corrosion during a subterranean treatment operation comprising using an acidic treatment fluid comprising ... 08/10/06 - 20060178277 - Fracturing method using aqueous or acid based fluids An improved method and fracturing fluid for hydraulic fracturing of a subterranean formation, the fracturing fluid including a surfactant, a water soluble or dispersible anionic organic salt, an acid and a low molecular weight organic solvent. ... 07/27/06 - 20060166840 - Drilling fluids containing biodegradable organophilic clay where M− is an anion such as a chloride, methyl sulfate, bromide, acetate, or iodide ion; R1 is an alkyl group such as a saturated hydrocarbon with 10 or more carbons; R2, R3, and R4 are the same or different alkyl groups such as a methyl, ethyl, or benzyl group, ... 07/27/06 - 20060166839 - Methods of using drilling fluids containing biodegradable organophilic clay Methods of treating a wellbore comprise displacing a drilling fluid comprising an organophilic clay treated with a quaternary ammonium surfactant having an amide linkage into the wellbore. Methods of drilling a wellbore comprise: applying torque to a bit within the wellbore and concurrently applying force to urge the bit to ... 03/02/06 - 20060046939 - Alcohol acidizing composition for treating a well to increase production An alcohol acidizing system for use in acidizing and cleanup in oil wells and gas wells. The system comprises an aqueous acid, such as hydrochloric acid, and at least one of an alkyl alcohol, such as methanol, ethyl alcohol, iso-propanol or the like, or any mixture thereof, an acetylenic alcohol ... 01/26/06 - 20060019836 - Multicomponent viscoelastic surfactant fluid and method of using as a fracturing fluid There is a viscoelastic fluid. The fluid has one or more cationic surfactants selected from the group consisting of certain quaternary salts, certain amines, and combinations thereof; one or more anionic polymers/anionic surfactants; one or more of certain zwitterionic/amphoteric surfactants; and water. There is also a method of fracturing a ... 10/13/05 - 20050227876 - Drag-reducing agent for use in injection water at oil recovery The present invention relates to the use of a drag-reducing agent in an amount of 50-400 ppm in water having an electrolyte content of 0.01-7% by weight. The drag-reducing agent comprises two zwitterionics, each comprising acyl containing surfactant and an anionic surfactant, where the hydrophilic group is a sulphate, a ... 06/23/05 - 20050137095 - Acidizing stimulation method using viscoelastic gelling agent A method of acidizing a subterranean formation involves the use of a composition containing a solution of a viscoelastic amidoamine oxide surfactant and an HF-containing acidizing solution. The composition typically contains from about 0.1 to about 8 weight percent of surfactant solution and from about 92 to about 99.9 weight ... ### FreshPatents.com Support |
