Abstract: A frangible disk sub includes a housing, a carrier movably disposed in the housing, and a frangible disk sealedly disposed in the carrier. The sub further includes a breaker concealed within a breaker housing and a breaker housing movement inhibitor. A method includes pressuring the disk to exceed a threshold pressure, moving the disk, carrier and breaker mechanism relative to the housing. The method further includes causing the breaker to contact the stop, exposing a hard point of the breaker, and driving the disk into the hard point.

Abstract: A downhole tool includes a tubular having an outer surface, an inner surface, a recess extending from the inner surface toward the outer surface, and an opening extending from the outer surface to the recess. A hydraulic passage extends through the tubular. The hydraulic passage includes an inlet, a first and a second branch. The second branch is fluidically exposed at the inner surface. A piston is arranged in the recess. A locking ring is arranged radially inwardly of the piston and a member is arranged in the tubular spaced from the inner surface. Application of hydraulic pressure in the first branch urges the piston radially inwardly clamping the locking ring against the member and application of hydraulic pressure in the second branch urges the member axially in a first direction relative to the tubular.

Abstract: An indexing valve system includes a first tubular having an outer surface portion, an inner surface portion defining a passage portion, and a plurality of indexing components. A second tubular is axially aligned with the first tubular. The second tubular includes an outer surface section, an inner surface section defining a passage section, and a plurality of indexing members that selectively inter-engage with the plurality of indexing components. The inner surface section including a plurality of indexing elements. An insert extends into, and is axially shiftable relative to, the passage portion and the passage section. The insert includes an outer surface supporting an indexer that selectively engages with the plurality of indexing elements to rotate the second tubular relative to the first tubular.

Abstract: An indexing valve system includes a tubular having an inner surface portion defining a passage portion, a first plurality of indexing components provided on the inner surface and a second plurality of indexing components provided on the inner surface portion. A valve sleeve is arranged in the passage portion. The valve sleeve includes a first plurality of indexing elements that selectively engage with the first plurality of indexing components, a second plurality of indexing elements that selectively engage with the second plurality of indexing components, and an inner surface section defining a passage section. The inner surface section includes a plurality of indexing step members. An insert extends into the passage section. The insert includes an outer surface supporting an indexer that selectively engages with the plurality of indexing step members to shift the valve sleeve between the first plurality of indexing components and the second plurality of indexing components.
