Abstract
An integrated managed pressure drilling ('MPD') riser joint includes an annular sealing system that allows for the installation, engagement, service, maintenance, disengagement, removal, or replacement of one or more sealing elements while maintaining a pressure tight seal on the annulus without a drill string isolation tool, or equivalent thereof. The integrated MPD riser joint is limited to the annular sealing system and a flow spool, or equivalent thereof, disposed directly below the annular sealing system, without any intervening pressure containment devices or systems. Advantageously, the integrated MPD riser joint does not require a drill string isolation tool, or equivalent thereof, and may be substantially shorter in length and weigh substantially less than a conventional integrated MPD riser joint. The reduction in size and weight enables adoption of MPD technology in applications where conventional integrated MPD riser joints are not economically feasible or are otherwise precluded from use.
