Abstract
A system includes a drill pipe and a rotating control device including a housing defining a bore through which the drill pipe extends during a managed pressure drilling operation, a sealing element disposed in the housing that is configured to seal against the drill pipe to block fluid flow through an annular space surrounding the drill pipe, a bearing assembly disposed in the housing that enables the sealing element to rotate relative to the housing, and means for detecting eccentricity or misalignment of the drill pipe within the rotating control device during the managed pressure drilling operation.
