  • Smart circulation sub
    Patent number: 11091983
    Abstract: A circulation sub assembly for circulating fluids in a subterranean well includes a circulation sub body that is a generally tubular shaped member with a sub central bore. A circulation port extends through a sidewall of the circulation sub body. A valve member is moveable between a closed position where the valve member prevents a flow of fluid through the circulation port and an open position where the valve member provides a fluid flow path through the circulation port. An actuation assembly includes an isolated hydraulic fluid system operable to move the valve member between the closed position and the open position. A control system includes an electronic processor, a memory, a data transmitter, and a data receiver. The control system is operable to instruct the actuation assembly to move the valve member between the closed position and the open position.
