Abstract: A downhole system for multistage fracturing wherein a stopper assembly is installed in a plugging device in manner that allows pressure integrity from above the plugging device, and the stopper assembly is further configured to allow a bore of the plugging device to open with an at least minimal pressure from therebelow in order to remove a stopper from a baffle in order to open a flow path through the plugging device in either direction.

Abstract: A downhole tool suitable for use in a wellbore, the tool having a cone mandrel having a dual-cone outer surface. The downhole tool includes a carrier ring disposed around one end of the cone mandrel. There is a slip disposed around or proximate to an other end of the cone mandrel. The cone mandrel has inner flowbore extending therethrough from the proximate end to the distal end.

The downhole tool includes a carrier ring disposed around one end of the cone mandrel, and a seal element disposed around the carrier ring. There is a slip disposed around or proximate to an other end of the cone mandrel.

Abstract: A downhole tool suitable for use in a wellbore, the tool having a double cone having a dual-cone outer surface. The downhole tool includes a carrier ring disposed around one end of the double cone, and a slip disposed around or proximate to an other end of the double cone. There is a guide assembly engaged with the slip.

Abstract: A downhole optic fiber wet-connect system includes first and second matable portions of a tool body; first and second matable portions of a connector. Further included is a first magnet associated with one of the first and second matable portions and a second magnet associated with the other of the first and second matable portions, the first and second magnets being oriented to attract one another; a first opening in one of the first and second matable portions of the tool body; a second opening in the other of the first and second matable portions of the tool body; and at least one of the first and second openings in the first and second matable portions of the tool body configured and dimensioned to loosely receive one of the first and second matable portions of the connector therein and a method for wet-connecting an optic fiber in a downhole environment.

First and second matable portions of a connector body further including a first magnet associated with one of the first and second matable portions of the connector body, and a second magnet associated with the other of the first and second matable portions of the connector body. The first and second magnets being oriented to attract one another. A first opening in one of the first and second matable portions of the tool body. A second opening in the other of the first and second matable portions of the tool body. At least one of the first and second openings in the first and second matable portions of the tool body being configured and dimensioned to laterally loosely receive one of the first and second matable portions of the connector body therein and method.

Abstract: An inflatable packer having a sealing section, with noncontinuous ribs, is provided in combination with a ribbed element, which provides anchoring capabilities in tandem with the partially ribbed element which provides sealing capabilities in downhole applications.
