The delayed gel breaking properties will lead to the controlled breaking of the fracturing fluid that reduces ... 10/19/06 - 20060234873 - Thermal stability agent for maintaining viscosity and fluid loss properties in drilling fluids A method of increasing the thermal stability of an aqueous wellbore fluid that includes a viscosifying agent, involves formulating the wellbore fluid so as to include an effective amount of a thermal stability compound selected from the group of gallic acid, gallow tannins, esters of gallic acid, salts of gallic ... 10/19/06 - 20060234872 - Low damage treatment fluids and methods of using the same The invention relates to novel wellbore treatment methods and fluids using compositions formed from an aqueous medium, a regularly substituted hydrophilically functional polysaccharide having a degree of substitution from about 0.1 to about 0.5, wherein the percent of insoluble polysaccharide is about 10% or less, and a crosslinker. The wellbore ... 10/19/06 - 20060234871 - Sealant composition comprising a gel system and a reduced amount of cement for a permeable zone downhole A sealant composition for servicing a wellbore comprising at least one gel system, a leak off prevention material and water. ... 09/14/06 - 20060205606 - Methods and compositions of controlling the rheology of a diutan-containing well treatment fluid at high temperatures The invention provides a method for treating a subterranean formation penetrated by a wellbore, the method comprising the steps of formulating a treatment fluid and introducing the treatment fluid through the wellbore. The treatment fluid comprises water; diutan; and a sufficient amount of salt to increase the density of the ... 09/14/06 - 20060205605 - Well treatment composition crosslinkers and uses thereof This invention relates to compositions used in treating subterranean formations, which include a hydrated polymer, and a dry blended multi-functional component. The hydrated polymer and dry blended multi-functional component are mixed at the ground surface of a wellsite, and subsequently injected into the formation providing controlled delay in crosslinking to ... 08/10/06 - 20060178276 - Energized fluids and methods of use thereof The present invention relates to novel aqueous wellbore treatment fluids containing a gas component, a heteropolysaccharide, an electrolyte, and a surfactant, wherein the fluids may further include an organoamino compound. The fluids exhibit good rheological properties at elevated temperatures. Methods of using fluids containing at least an aqueous medium, a ... 07/27/06 - 20060166837 - Methods of treating subterranean formations with heteropolysaccharides based fluids Disclosed are methods of treating subterranean formations with rapidly hydratable treatment fluids based upon heteropolysaccharides. In particular, the invention relates to treatment methods with fluids containing a heteropolysaccharide, aqueous medium, and an electrolyte, wherein the fluids may further include a gas component, a surfactant and/or an organoamino compound. The fluids ... 07/27/06 - 20060166836 - Energized fluids and methods of use thereof The present invention relates to novel aqueous wellbore treatment fluids containing a gas component, a heteropolysaccharide, an electrolyte, and a surfactant, wherein the fluids may further include an organoamino compound. The fluids exhibit good rheological properties at elevated temperatures. Methods of use of fluids comprising at least an aqueous medium, ... 05/04/06 - 20060094604 - Method and biodegradable super absorbent composition for preventing or treating lost circulation A lost circulation material and method for treatment employing the material is provided that has particular utility in offshore applications because the material may be used with saltwater or brine, as well as with fresh water, and is biodegradable. The material comprises a biodegradable superabsorbent polysaccharide polymer that is preferably ... 04/06/06 - 20060073988 - Fast hydrating guar powder, method of preparation, and methods of use A guar or a guar derivative powder having a D50 particle size of less than 40μ which reaches at least 70% hydration within 60 seconds at about 70 degrees F., is disclosed. The powder can be used in applications such as drilling fluid; fracturing fluid; gravel packing fluids; completion fluid; ... 12/08/05 - 20050272612 - Galactomannan based well treating fluids A well fracturing fluid is shown which includes an aqueous base fluid, a hydratable polymer, such as a guar gum, and a suitable crosslinking agent for crosslinking the hydratable polymer to form a polymer gel. The hydratable polymer has a higher molecular weight which is achieved by improvements in the ... 11/03/05 - 20050245401 - Propped fracture with high effective surface area Propped fractures in formations from which fluids are produced are described that have wormholes extending out into the formations from the faces of the fractures at locations distant from boreholes. Methods are given for creating such propped fractures having wormholes in which either a closed propped fracture is formed and ... 10/13/05 - 20050227874 - Composition and method for fracturing subterranean reservoirs A composition and method for fracturing subterranean reservoirs by including a partially esterified, polyalkoxylated polyols as an oxidizing breaker retarder in the aqueous fracturing fluid to delay its gel breaking properties with the oxidizing breaker.
