A downhole system for multistage fracturing having at least a first cluster of valves. The first cluster of valves has a frac valve. The first cluster of valves also has a flex valve. A single plugging device is operable to pass through all of the valves of the first cluster of valves and leave all of them closed.

Systems and methods for multistage fracturing

A downhole tool suitable for use in a wellbore, the downhole tool having a packer chassis. There is a first fingered member disposed on the chassis, and also a second fingered member disposed on the chassis. In a run-in configuration, the first fingered member has a slot proximately aligned with a midpoint of a finger of the second fingered member.

Downhole tool with backup ring assembly

A plugging device for use in multistage fracturing a subterranean formation. The plugging device includes a plug body having a distal end, a proximate end, and an outer surface. There are a plurality of grooves disposed on the outer surface, and an index sleeve movingly disposed on the outer surface, the index sleeve configured to engage the plurality of grooves. The index is incrementable with respect to the plurality of grooves from the distal end toward the proximate end.

Systems and methods for multi-stage well stimulation

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.

A downhole system for multistage fracturing having a first cluster of valves, and a second cluster of valves downhole from the first cluster. Each of the first and second cluster of valves has a frac valve. At least one of the first and the second cluster of valves has a flex valve. A single plugging device is used to open all of the valves in the second cluster, but leaves all valves in the first cluster closed.

Systems and methods for multi-stage fracturing

A downhole tool suitable for use in a wellbore, the tool having a chassis or mandrel, with a center element and a plurality of support elements disposed therearound. The downhole tool also includes a first fingered member, and a second fingered member. In a run-in configuration, the first fingered member has a slot axially aligned with a midpoint of a finger of the second fingered member.

An expandable tubular assembly includes an expander for expanding a tubular. The expander may be hydraulically actuated. A bore obstruction object may be received in a receptacle sleeve that is a modular component of the expandable tubular assembly. In this respect, the expandable tubular assembly may be quickly fitted with a receptacle sleeve designed to receive selected type of bore obstruction object.

Apparatus and method for completing a wellbore

A portable, free standing apparatus is provided to support or cradle a hand-held electric hair dryer at various heights and angles, allowing the operator of these types of hair dryers free use of both hands while drying hair.
