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.
