    摘要: The present invention provides reduced-density coated particulates and methods for enhancing the transport of such particulates into well bores and fractures, and for enhancing the conductivity and permeability of subterranean formations using such particulates, and for sand control treatments using such particulates. The reduced-density, coated particulates of the present invention generally comprise particulate having a surface and a coating wherein the surface comprises a porous or partially hollow geometry and coating is capable of trapping a fluid between the particulate's surface and the coating.

    摘要: The present invention is directed to a low cost method and apparatus for fracturing a subterranean formation. The invention involves using a centrifugal pump to combine a fracture fluid, a sand suspension and liquid additive and discharge a mixture of these components into a high pressure pump that injects the mixture into the subterranean formation. The apparatus employs a control pinch valve to precisely control the amount of sand suspension being added to the mixture. The apparatus eliminates the need for expensive blenders, other equipment and associated personnel and provides a low cost means of fracturing the subterranean formation.

    摘要: The present invention is directed to a method and apparatus for fracturing a subterranean formation which use a fracturing tool. The fracturing tool includes a hydrajet tool, with at least one fluid jet and at least one fracturing port extending through the liner. The fracturing tool further includes a rotating sleeve with at least one interior fracturing port and at least one interior fluid jet port. Finally, the fracturing tool may include a power unit capable of changing the orientation of the rotating sleeve. During fracturing operations, fracturing fluid is pressured through the fluid jet to form microfractures. The orientation of the rotating sleeve may then be changed and fluid may be forced through the fracturing ports to form fractures by the stagnation pressure of the fracturing fluid.
