Abstract: The present disclosure describes systems and methods for flow-activated plug assembly flow seat initiation, which in some aspects may comprise sealing a plug within a downhole bore, and may include a plug assembly comprising a frustoconical tube; a tubular mandrel positioned longitudinally through the frustoconical tube and having port(s) fluidly connecting a mandrel bore with the bore of the frustoconical tube, and having a shear member extending from the mandrel; and a ball configured to fluidly seal the proximal end of the tubular mandrel; wherein the tubular mandrel is configured to move between a first position having a fluid passageway through the ports and a second position wherein the shear member has been sheared away when a predetermined fluid pressure is applied to the plug assembly and the tubular mandrel is positioned relative to the frustoconical tube such that the port(s) are blocked, closing the fluid passageway.

Abstract: A downhole tool comprising magnesium is placed in a well bore in a subterranean formation for performance of a downhole operation. After performance of the downhole operation, rather than mechanically retrieving or removing the tool, at least a portion of the magnesium in the downhole tool is dissolved by contacting the downhole tool with an aqueous ammonium chloride solution.

Abstract: The present disclosure describes systems and methods for setting and sealing a plug in a casing within a downhole bore, including deploying into the casing a plug assembly comprising a tubular metal seal; deploying into the casing a setting tool; expanding the tubular metal seal radially to a first radial diameter with the setting tool by moving the setting tool longitudinally such that a tapered exterior portion of the first end of the setting tool engages a tapered interior portion of the first end of the tubular metal seal; and removing the setting tool from the casing. The method may comprise expanding the tubular metal seal radially to a second radial diameter by pumping fluid into the plug assembly such that the exterior of the tubular metal seal engages an interior of the casing.

Abstract: The present invention is directed to disposable composite downhole tool formed of a resin-coated fiber. The fiber is formed of a degradable polymer, such as a poly(lactide) or polyanhydride. The resin is formed of the same degradable polymer as the fiber. It chemically bonds to the fiber, thereby making a strong rigid structure once cured. The fiber may be formed into a fabric before being coated with the resin. Alternatively, the fiber is formed of a non-biodegradable material.
