Abstract: A downhole tool for connecting an interior of a casing to a formation, the downhole tool including an inner housing extending along a longitudinal axis X; an outer housing that encloses the inner housing and forms first to fourth chambers; a first piston that separates the first and second chambers; a second piston that separates the third and fourth chambers; a port that is configured to fluidly communicate an outside and inside of the downhole tool; and a stopping mechanism that prevents the second piston from opening the port. The second piston is positioned to separate the port into an outer portion and an inner portion to interrupt a fluid communication between the outside and inside of the downhole tool.

Abstract: There is a shaped charge for making an asymmetrical perforation into a casing. The shaped charge includes a case extending along a symmetry axis X and having a back wall and an open end; an explosive material located within the case; a liner located within the case, over the explosive material; a booster material; and an asymmetrical feature. The asymmetrical feature is selected to generate an asymmetrical perforation into the casing.

Abstract: A setting tool (402) for setting a plug in a well, the setting tool (402) including a body (404) extending along a longitudinal axis X; a rod (408) extending along the longitudinal axis of the body (404), from an upstream end (402B) to a downstream end (402A) of the body (404); a chamber (406) formed at the downstream end (402A) of the body; and a restriction element (450) located in the chamber (406). The rod (408) extends through the entire chamber (406) and the restriction element (450) is located between the rod (408) and a wall (404A) of the chamber (406).

Abstract: A fluid control system includes a fluid control device configured to be connected to at least one of two casing elements in a well, for controlling a fluid flow between a bore of the fluid control device and a zone located outside the casing elements; and a tracer material located within an inner chamber of a body of the fluid control device, the tracer material being uniquely associated with the fluid control device. The fluid control device is configured to release, when activated, the tracer material out of the inner chamber.
