Abstract
A rotating control device includes an inner seal assembly configured to be disposed around a drill string and includes at least one pressure seal. The rotating control device includes an outer body configured to be operatively coupled to a blowout preventor. The outer body includes a primary cavity configured to receive, at least partially, the inner seal assembly, and a secondary cavity configured to direct fluid flow and including at least one ramping surface configured to reduce a pressure fluctuation. The primary cavity and the secondary cavity are fluidly connected by a passageway therebetween. The rotating control device also includes at least one outer seal configured to prevent fluid leakage between the outer body and the inner seal assembly; at least one outer bearing assembly configured to facilitate rotation of the inner seal assembly; and a fluid outlet fluidly connected to other drill equipment configured to manage a wellbore pressure.
