Abstract: Rotating control device related oilfield pressure control is accomplished by upper (26a) and lower (26b) seal members configured to seal around a tubular (40), a chamber (44) defined between the upper and lower seal members; and wherein fluid enters and/or exits the chamber via some device or structure (60, 70). Such a device or structure could be a relief valve (60), a first accumulator (70), a pressure control valve, an orifice, and/or a void space in a seal member in a location which contacts the tubular.
