20090095472 | WELL TREATMENT FLUID COMPOSITIONS AND METHODS OF USE THAT INCLUDE A DELAYED RELEASE PERCARBONATE FORMULATION - A well treatment fluid and method of use includes water, at least one hydratable polymer, an optional crosslinking agent, and a delayed release percarbonate formulation effective to reduce initial viscosity of the fluid after a period of time. Also disclosed are processes for fracturing a subterranean formation. | 04-16-2009 |
20100200239 | FRICTION REDUCING COMPOSITIONS FOR WELL TREATMENT FLUIDS AND METHODS OF USE - Friction reducing compositions for use in well treatment fluids generally include an aqueous fluid; a polymeric friction reducer; and 3,5-dimethyl-1,3,5-thiadiazinane-2-thione. It has been found that the combination of the polymeric friction reducer; and 3,5-dimethyl-1,3,5-thiadiazinane-2-thione unexpectedly and synergistically increases friction reduction and inversion behavior, where applicable. Also disclosed are methods for the fracturing of a subterranean hydrocarbon bearing formation to stimulate the production of the hydrocarbons by injecting the friction reducing composition. | 08-12-2010 |
20100218950 | BIOCIDE FOR WELL STIMULATION AND TREATMENT FLUIDS - A well stimulation and or treatment fluid that includes water, other additives, and a biocide consisting of 3,5-dimethyl-1,3,5-thiadiazinane-2-thione in an amount effective to inhibit bacterial growth and minimize antagonistic reactions between the biocide and other additives. Also disclosed are well injection compositions, stimulations, squeezing, waterflood, packing, cement compositions, and methods for cementing. | 09-02-2010 |
20110278008 | WELL TREATMENT FLUID COMPOSITIONS AND METHODS OF USE THAT INCLUDE A DELAYED RELEASE PERCARBONATE FORMULATION - A well treatment fluid and method of use includes water, at least one hydratable polymer, an optional crosslinking agent, and a delayed release percarbonate formulation effective to reduce initial viscosity of the fluid after a period of time. Also disclosed are processes for fracturing a subterranean formation. | 11-17-2011 |
20130165352 | Well Treatment Fluid Compositions and Methods of Use That Include a Delayed Release Percarbonate Formulation - A well treatment fluid and method of use includes water, at least one hydratable polymer, an optional crosslinking agent, and a delayed release percarbonate formulation effective to reduce initial viscosity of the fluid after a period of time. Also disclosed are processes for fracturing a subterranean formation. | 06-27-2013 |
