摘要： Methods for creating packers at a desired location or locations within a wellbore for use in specific wellbore applications. A slurry of fluid medium and hydrolysable particulate matter is flowed to a downhole position and dehydrated. At this location, the particulate matter is released from the fluid medium and accumulated. The continual accumulation of the slurry and consequent deposition of particulate matter creates a degradable packer at the desired location within the wellbore. The particulate matter may be formed of an acid particle which may be removable, degradable, or hydrolysable under certain conditions of temperature, time, hydration, pH, and/or pressure. Either simultaneous with or subsequent to a wellbore activity, the packer is partially or completely removed from the wellbore.

摘要： A dry solid composition is disclosed that, when added to an aqueous liquid, provides a slurry that can be used in sandstone acid fracturing. The slurry generates hydrofluoric acid downhole to etch the sandstone fracture faces created. The chemical and physical properties of the composition result in very uneven etching of the fracture faces, enhancing the fluid conductivity of the final fracture. Optionally, inert masking materials may be included in the dry composition, or added to the slurry, to increase the inhomogeneity of the etching and further increase the fluid conductivity.
