Abstract: 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.

Abstract: A controlled-gelation aqueous solution is proposed. The solution contains a hydrophobically-aggregating gelling agent, and an effective amount of an inhibitor which suppresses hydrophobic aggregation of the gelling agent. The inhibitor is soluble in water so that when the controlled-gelation aqueous solution contacts aqueous media the inhibitor disperses and gelation occurs. However, the inhibitor is substantially insoluble in hydrocarbons so that when the controlled-gelation aqueous solution contacts hydrocarbon media the inhibitor continues to suppress said hydrophobic aggregation and gelation is suppressed. The solution may be used to control the flow of water into oil wells, making it possible to reduce the water cut.

Abstract: A C-plate assembly for use in a cable-guided fishing assembly is disclosed. The disclosed invention provides a C-plate assembly in which a closure member is slidable from an open position, which allows a wellbore tubular or other item to be positioned in the cut-out section of the C-plate base, to a closed position, which closes the opening to the cut-out section and thereby prevents the wellbore tubular or other item from being unintentionally knocked free from the cut-out section during a fishing operation. The closure member is locked in place in the closed position by inserting the ends of a movable handle extending off of one side of the C-plate base into openings in the C-plate base. The ends of the movable handle are spring loaded to allow for the ends to be pulled out of the openings in the C-plate base such that the closure member can be “unlocked” and moved from a closed position to an open position during operation.
