Abstract: An annular drilling device is provided that employs an active or passive, stationary sealing element. More specifically, rotating annular drilling devices commonly used depend on externally pressurized sealing elements that are energized by wellhead pressure or hydraulic pressure to grip a rotating drill pipe and rotate with the drill string. Thus, a plurality of rotary seals and bearings must be used. Here, however, the passive or active sealing element is stationary, thereby eliminating the need for bearings, etc. The passive or active stationary sealing element is made of a low-friction material that contacts the drill pipe, creates a seal, and does not adversely affect drilling operations.
