Improved methods for stabilizing unconsolidated subterranean formation particulates and reducing permeability of a subterranean formation to water. Some methods describe methods of stabilizing unconsolidated subterranean formation particulates and reducing the permeability of water comprising providing a portion of a subterranean formation that comprises unconsolidated formation particulates; introducing a fluid comprising a relative permeability modifier into at least a portion of the subterranean formation so as to at least partially reduce the permeability of that portion of the subterranean formation to water; and, introducing a fluid comprising a consolidating agent into at least a portion of the subterranean formation so as to at least partially consolidate the unconsolidated formation particulates.

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.

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.

Methods that comprise: providing a carrier fluid comprising a delayed breaker; providing a plurality of proppant aggregates comprising a binder fluid and a filler material; suspending the plurality of proppant aggregates in the carrier fluid; introducing the carrier fluid into the subterranean formation at or above a pressure sufficient to create or enhance at least one fracture, the carrier fluid comprising the plurality of proppant aggregates suspended therein; allowing the carrier fluid to break so as to reduce the viscosity of the carrier fluid; and recovering at least a portion of the carrier fluid from the at least one fracture wherein at least a substantial portion of the plurality of proppant aggregates remains in the at least one fracture so as to create a high porosity propped fracture.
摘要:
Light weight high strength particles and methods of treating subterranean producing zones utilizing the particles are provided. The light weight high strength particles of the invention are basically comprised of sintered mixtures of a base material and hollow microspheres.
摘要:
The present invention relates to methods of stabilizing an unconsolidated portion in a subterranean formation and stimulating fluid production from the stabilized portion. Some embodiments of the present invention provide methods of substantially stabilizing a portion of a subterranean formation penetrated by a well bore and stimulating fluid production therefrom comprising placing a stabilizing composition into a near well bore area of a portion in a formation to create a stabilized portion; and, stimulating the stabilized portion so as to place the well bore in fluid communication with both the stabilized portion in the near-well bore area and an unstabilized portion of the formation in the far-well bore area.
