Abstract: A frac-ball for use with a well casing segmentation device and a method of controlling fluid flow through a well casing segmentation device are provided. The frac-ball includes a body having a shell configuration defined by one or more walls, with each wall having an exterior surface and an interior surface. The interior surfaces define an enclosed interior cavity. One or more structurally weakened regions are disposed in the one or more walls.

Abstract: A casing segmentation device and system, and a method for selectively providing a fluid flow passage through a casing segmentation device disposed within a well casing segment is provided. The casing segmentation device includes a body and a fracture mechanism. The body has a forward end, an aft end, a plug seat, and an internal passage. The plug seat is configured to receive a mating plug. The internal passage extends between the forward end and the aft end and through the plug seat. The fracture mechanism includes an amount of energetic material and a trigger mechanism. The trigger mechanism is configured to selectively cause a detonation of the amount of energetic material.

Abstract: A frangible joint for a structure is provided. The structure is provided having a first portion and a second portion with a feature defining a fracture plane disposed therebetween. A first housing is coupled to a first side of the first portion, the first housing having a first slot adjacent the first side and a first wall member adjacent the feature. A second housing is coupled to the second portion the first housing, the second housing having a second slot adjacent the second side and a second wall adjacent the feature opposite the first wall. A first expanding tube assembly is disposed within the first slot. The first expanding tube assembly having a first tube containing a first explosive core. A second expanding tube assembly is disposed within the second slot. The second expanding tube assembly having a second metallic tube containing a second explosive core.
