    摘要： A system and method is provided for filtering in a wellbore during various well related operations while limiting the potential for plugging. A well screen is used for filtering particulates from a fluid at a wellbore location. To remove accumulated material and avoid plugging, the well screen may be flexed via pressure differentials created across the well screen. The flexing of the well screen breaks free the accumulated materials, thereby avoiding premature job failure.

    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.
