摘要： The present invention provides methods and compositions for treating clay-bearing aggregates, particularly those used for construction purposes, whereby inclusion of fines is maximized due to minimization of clay washing which tends to remove such fines, and whereby performance of the aggregate-containing construction material is enhanced. Exemplary methods comprise introducing to clay a water-soluble, functionalized polyamine comprising a water-soluble polyamine formed by reacting an amine compound with an epoxy compound, the polyamine thus reacted being functionalized through the use of certain halide, sulfate, or epoxy compounds.

摘要： The present invention relates to subterranean drilling operations, and more particularly, to drilling fluids that may be used to drill a well bore in a subterranean formation that may demonstrate improved shale inhibition and methods of using such drilling fluids in subterranean formations. One embodiment of the methods of the present invention provides a method of drilling a well bore in a subterranean formation comprising providing a drilling fluid comprising an aqueous-based fluid and a shale inhibiting component comprising a nanoparticle source; and placing the drilling fluid in the well bore in the subterranean formation. Another embodiment of the present invention provides a method of flocculation comprising providing a fluid comprising suspended particles, and adding a shale inhibiting component comprising a nanoparticle source to the fluid comprising suspended particles to form flocculated particles.

摘要： Aqueous-based insulating fluids that have greater stability at high temperatures with lower thermal conductivity may be used, for example, in applications requiring an insulating fluid such as pipeline and subterranean applications. For example, a method may include providing an aqueous-based insulating fluid in an annulus between a riser column and an outer casing disposed thereabout, the riser column connecting a wellbore penetrating a subterranean formation to a floating surface rig; and flowing a fluid through the riser column and the wellbore.
