20060211580 - Well treating compositions containing water superabsorbent material and method of using the same: A well treating composition containing a polysaccharide-based water-superabsorbent material has particularly applicability as a thermal insulating, fracturing or acid stimulation fluid. The water-superabsorbent material is capable of absorbing, at a minimum, its own weight. Particularly effective are biodegradable materials containing guar gum and carrageenan. The composition may further contain a...

20060205603 - Method for inhibiting hydrate formation: A method for inhibiting the formation of gas hydrates in a petroleum fluid having hydrate-forming constituents is claimed. More specifically, the method can be used to treat a petroleum fluid, such as natural gas conveyed in a pipe, to inhibit the formation of a hydrate flow restriction in the pipe....

20060205604 - Membrane forming in-situ polymerization for water based drilling fluids: A method of increasing shale formation stability with a water based drilling fluid, the method including: delivering to the shale formation a drilling fluid formulated to include an aqueous fluid; a first reactant which is a soluble monomer, oligomer, or polymer with exposed ketone, aldehyde, or aldol groups or with...

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...

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...

20060205607 - Methods of treating subterranean zones and viscous aqueous fluids containing xanthan and a combination cross-linker-breaker: Viscous aqueous fluids containing xanthan biopolymer gelling agent and a combination cross-linker and delayed breaker are provided. A viscous cross-linked aqueous treating fluid of the invention comprises water, a xanthan polymer gelling agent, and a combination cross-linker and delayed breaker for said xanthan biopolymer gelling agent....

20060205608 - Filter cake degradation compositions and methods of use in subterranean operations: The present invention relates to methods and compositions for degrading filter cakes in subterranean formations, and more specifically, to improved methods and compositions for degrading filter cakes that comprise acid-soluble portions and polymeric portions. In one embodiment, the present invention provides a method of degrading a filter cake comprising an...

20060205609 - Esterquat acidic subterranean treatment fluids and methods of using esterquats acidic subterranean treatment fluids: The present invention relates to acidic treatment fluids that comprise an acid fluid and an ester-containing quaternary ammonium compound (“esterquat”) and methods of their use. 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...

20060199742 - Water-soluble, low substitution hydroxyethylcellulose, derivatives thereof, process of making, and uses thereof: This invention relates to water-soluble hydroxyethylcelluloses (HECs) and derivatives thereof having a hydroxyethyl molar substitution (HE-MS) from about 0.7 to 1.3. These HECs are more efficient in thickening aqueous systems than prior art HEC products and show unique rheology in low water activity systems. These HECs can be distinguished from...
