Patent attributes
A well tool comprising a housing comprising ports and defining a flow passage, an actuator, a dual magnetic sensor actuation assembly (DMSAA) in signal communication with the actuator and comprising a first magnetic sensor up-hole relative to a second magnetic sensor, and an electronic circuit comprising a counter, and wherein, the DMSAA detects a magnetic signal and determines the direction of movement of the magnetic device emitting the magnetic signal, and a sleeve slidable within the housing and transitional from a first position in which the sleeve prevents fluid communication via the ports to a second position in which the sleeve allows fluid communication via the ports, wherein, the sleeve transitions from the first to the second position upon recognition of a predetermined quantity of magnetic signals traveling in a particular direction.
