PRESSURE COMPENSATED DISCONNECT SYSTEM AND METHOD

摘要

A disconnect for facilitating release of a tool at a downhole, wellbore location. The disconnect utilizes an upper portion and a lower portion connected at least in part by a shear member. The disconnect uses a plurality of pressure areas to selectively expose the lower portion to balanced, counteracting axial forces. The pressure areas allow release or disconnection of the upper portion from the lower portion upon application of a predetermined tensile load without subjecting the tubing to an undesirably high tensile load.
