The present invention provides a bi-directional ball seat and method of use. In at least one embodiment, the present invention provides a fluid control system that includes a radial protrusion that can be selectively engaged and disengaged upstream and/or from a ball seat. For example, a ball can be placed in a passageway, engaged with a downstream ball seat, and the radial protrusion radially extended into the passageway distally from the seat relative to the ball. A reverse movement of the ball is restricted by the active radial movement of the radial protrusion into the passageway. The control system can be used to control a variety of tools associated with the well. Without limitation, the tools can include crossover tools, sleeves, packers, safety valves, separators, gravel packers, perforating guns, decoupling tools, valves, and other tools know to those with ordinary skills in the art.
A method of using a fluid control system for a hydrocarbon well, the control system comprising a first portion having at least one actuator, an inner sleeve slidably disposed with the first portion and forming a longitudinal passageway, and at least two radial protrusions disposed at least partially in the inner sleeve and exposed to the passageway, the at least two radial protrusions being adapted to selectively extend into and retract from the passageway, the method comprising:
