Hydraulically controlled burst disk subs and methods for their use
Abstract:
A method and apparatus for treating a subterranean section surrounding a wellbore with a fluid. In one embodiment, the apparatus comprises a three-dimensional tubular element capable of fluid flow in a wellbore with at least one burst disk with a pre-determined pressure rating positioned at a desired location on the tubular wherein the burst disk ruptures at the pre-determined pressure at the desired location on the tubular in the wellbore. The method provides the ability to choose the order in which the subterranean interval sections surrounding a wellbore are treated with fluid.
