A downhole tool used in the pressure isolation of adjacent subterranean formations. The downhole tool may comprise flow restriction devices along the outer circumference for impeding flow along the length of the tool. The tool may further comprise a perforating gun and an accumulator. Impeding flow along the length of the tool provides a dynamic flow restriction within the wellbore that precludes fluid flowing from one subterranean zone to an adjacent zone.

Perforating gun assembly and method for controlling wellbore fluid dynamics

An anchoring sub used in combination with hydrocarbon exploration and production tools, such as perforating guns and logging devices, within a wellbore. The anchor sub is reversible and includes a mandrel, a slip assembly and a slip cone, where the slip assembly selectively travels up and down the mandrel and is able to mate with the slip cone. The anchor sub secures itself to the inner circumference of a wellbore when the slip assembly is mated with the slip cone. Mating and de-mating of the slip assembly with the slip cone is accomplished by selective up and down movement of the anchor sub.
