Abstract: A FAC tool for use in a well comprising a well casing. The FAC tool comprises a top drive connection for coupling the tool to a top drive; a push plate; a telescoping section coupling the push plate to the top drive connection; a packer cup configured to seal an annular space between the FAC tool and the well casing when the packer cup is energized; a packer element system comprising at least one packer moveable between a locked position in which the at least one packer is not energized, and an energized position, the packer element system being configured to seal the annular space between the FAC tool and the well casing when in the energized position; and a slip system comprising at least one slip, the slip system configured to lock the packer element in the energized position.

Abstract: A method and apparatus for communicating coded messages in a wellbore between a transmission node and a reception node is provided. The coded messages are messages are impressed upon a fluid column which extends between the transmission node and the reception node. A transmission apparatus is provided at the transmission node which is in communication with the fluid column, for altering pressure of the fluid column to generate at least a portion of the coded message. A reception apparatus is provided at the reception node. The reception apparatus includes a rigid structural component with an exterior surface which is in direct contact with fluid column and an interior surface which is not in contact with the fluid column, and a sensor assembly which detects elastic deformation of the rigid structural component. The transmission apparatus is utilized to alter pressure of the fluid column in a predetermined pattern to generate at least one coded message.
