摘要:
A method of treating a subterranean formation is provided, the method comprising the steps of: positioning a jetting tool in a wellbore penetrating the subterranean formation, wherein the jetting tool comprises at least one fluid jet forming nozzle; and delivering a curable composition through the jetting tool and to the formation, wherein the curable composition: cures to form a solid substance or a semi-solid, gel-like substance, and is a fluid having a sufficiently low viscosity to penetrate into the formation. The methods according to the invention are particularly suited for treating weakly consolidated or unconsolidated formations with a hardenable resin composition to help consolidate the formation.

A system and method for fracturing an earth formation surrounding a borehole includes an elongate conduit positioned in the borehole. A packer assembly is provided about the conduit and is adapted to seal an annulus between the conduit and the borehole. A packing passage is provided and adapted to communicate a first side of the packer assembly to the annulus between the conduit and the borehole on a second side of the packer assembly. The conduit has at least one inlet into the conduit on the second side of the packer assembly adapted to allow flow from outside of the conduit to the interior of the conduit. The conduit has at least one ported sub having at least one lateral jet aperture therein adapted to direct fluids within the conduit into the earth formation to fracture the earth formation.

Methods for stabilizing portions of a subterranean formation that comprise unconsolidated particulates. In one embodiment, the methods of the present invention comprise: providing a consolidating agent; introducing the consolidating agent into an unconsolidated portion of a subterranean formation through a dynamic diversion tool; and allowing the consolidating agent to at least partially consolidate the unconsolidated portion of the subterranean formation.
摘要:
Methods of stabilizing unconsolidated portions of a subterranean formation are provided. In one embodiment, the methods comprise: creating or enhancing at least two slots in an unconsolidated portion of a subterranean formation along a well bore, wherein the slots are positioned about 180 degrees from each other along the inner surface of the well bore; introducing a consolidating agent into the slots in the unconsolidated portion of the subterranean formation; and creating or enhancing at least one fracture in a portion of the subterranean formation.
摘要:
The present invention provides cement compositions that include degradable materials, and methods of using such compositions in subterranean cementing operations. An example of a method of the present invention includes: providing a cement composition that includes a hydraulic cement, and a degradable material; placing the cement composition in a subterranean formation; allowing the cement composition to set therein; and allowing the degradable material to degrade. Another example of a method of the present invention is a method of enhancing the mechanical properties of a cement composition including adding a degradable material to the cement composition and allowing the degradable material to degrade.
