  • Rotating control device, cool fluid circulation system and methods of operation
    Patent number: 8499854
    Abstract: Systems and methods for cooling a Rotating Control Device (RCD) and RCD insert during drilling operations are described. The system includes a body for connection between the RCD and a hot drilling fluid return outlet of a well head, the body including an inlet for injecting cool drilling fluid adjacent the RCD insert and an outlet for removing partially warmed drilling fluid. During operation, cool drilling fluid is circulated through the inlet and outlet such that cool drilling fluid is in direct contact with hot drilling fluid recovered from the well in a buffer zone adjacent the hot drilling fluid return outlet.
