Abstract: The disclosure provides a packing monitor, method, and gravel pack system for real-time monitoring of a particulate for improved gravel packing. Via the real-time monitoring, the quality of the gravel pack can be detected in real-time. Accordingly, a top-off procedure can be performed without additional tripping of the inner service tool string. Detecting when the gravel pack is approaching screen-out can also be determined in real-time. Detecting when screen-out is approaching allows the operator to prepare to stop pumping in case of miscalculations or early screen-out. In one example, the packing monitor includes: (1) a packing detector configured to, when stationary within the wellbore, obtain measurements indicating presence of a particulate in an annulus of the wellbore at different positions along a length of a screen; and (2) a packing controller configured to determine, based on the measurements, a status of the particulate in the annulus at the different positions.

Abstract: A steering lock locks a steering member with a lockbolt movable along an axis between locking and unlocking positions. A first member having a first cam surface is rotatable by an actuator in a first direction for locking the lockbolt. A second member having a second cam surface is engaged with the first cam surface. The second member is translatable along the axis in a locking direction by rotation of the first member. An unlocking spring is compressible through a range of movement of the second member in the first direction to store increasing potential energy. The cam surfaces are engaged such that unlocking of the lockbolt is carried out by the stored energy in the unlocking spring, which is released in a continuously increasing manner controlled by the actuator as the first member is rotated by the actuator in a second direction opposite the first direction.

Abstract: A steering lock for inhibiting rotation of a rotary steering member having a rib. A lockbolt is movable along a first axis between steering member-locking and -unlocking positions. A shuttle moves between a non-blocking position, in which the shuttle does not obstruct movement of the lockbolt from the steering member-locking position, and a blocking position, in which the shuttle obstructs movement of the lockbolt out of the steering member-locking position. An actuator is coupled to the shuttle and operable to drive the lockbolt to the steering member-locking position by moving the shuttle from the non-blocking position to the blocking position. The lockbolt is unbiased along the first axis.

Abstract: A steering lock for locking a rotary steering member against rotation. A lockbolt is movable along a first axis between steering member-locking and -unlocking positions. A shuttle moves between a non-blocking position, in which the shuttle does not obstruct movement of the lockbolt from the steering member-locking position, and a blocking position, in which the shuttle obstructs movement of the lockbolt out of the steering member-locking position. An actuator drives the lockbolt to the steering member-locking position by moving the shuttle to the blocking position. An output gear is drivable by the actuator. A rotary drive member has a first portion formed with gear teeth meshed with the output gear, and a second portion formed with a driving structure engaged with a follower structure of the shuttle, whereby the shuttle is configured to translate axially toward and away from the first axis when the rotary drive member rotates in place.

Abstract: An actuation device for a steering lock is operable to selectively lock a rotary steering member against rotation. A lockbolt is movable along a first axis between a steering member-locking position and a steering member-unlocking position. A shuttle is movable between a non-blocking position in which the shuttle does not obstruct movement of the lockbolt from the steering member-locking position to the steering member-unlocking position and a blocking position in which the shuttle obstructs movement of the lockbolt from the steering member-locking position to the steering member-unlocking position. An actuator is coupled to the shuttle and operable to move the shuttle from at least one of the non-blocking position and the blocking position to the other of the non-blocking position and the blocking position. The actuator has an output defining a second axis that is substantially perpendicular to the first axis.

Abstract: A steering lock for selectively inhibiting rotation of a rotary steering member having a rib includes a lockbolt movable along a first axis between a steering member-locking position, in which a distal tip of the lockbolt is positioned in interference with the rib, and a steering member-unlocking position, in which the distal tip of the lockbolt is positioned out of interference with the rib. A shuttle is movable between a non-blocking position, in which the shuttle does not obstruct movement of the lockbolt from the steering member-locking position to the steering member-unlocking position, and a blocking position, in which the shuttle obstructs movement of the lockbolt out of the steering member-locking position. An actuator is coupled to the shuttle and operable to drive the lockbolt to the steering member-locking position by moving the shuttle from the non-blocking position to the blocking position. The lockbolt is unbiased along the first axis.
