Abstract

A rupture apparatus () often deployed within a wall of a casing string () of an oil and gas well, comprising a housing () defining a housing bore () with a bore inlet and a bore outlet; a carriage carrying a rupturable component () the carriage being moveable in the housing bore between a rupturable position, an open and a closed position. Thus the bore can be opened or closed or closed subject to rupture of the rupturable component (). Moreover, after rupture the bore can still be closed. Wireless signals are normally used to for control, especially electromagnetic or acoustic signals. A pressure balancing port () may be defined in a wall of the housing allowing fluid communication between at least a portion of the housing bore, and an outside of the housing which can pressure-balance the carriage such that it remains stationary unless actuated.
