Abstract:
This disclosure includes riser-component assemblies and methods of assembling the same that are suitable for managed pressure drilling (MPD) systems. For example, this disclosure includes integrated flow spool and isolation tool riser components that can be permanently coupled together and that can be configured to pass through a rotary table or other rig equipment.

Claim (Index 1):
A riser-component assembly having a primary lumen, the assembly comprising:\n a first flange comprising:\n a first mating face configured to mate with a flange of a first adjacent riser segment, and \n a first central flange lumen in fluid communication with the primary lumen; \n a housing permanently coupled to the first flange, the housing having a first opening, a second opening, and a central chamber in fluid communication with the primary lumen and configured to receive an annular seal around a primary axis extending through the first and second openings such that the annular seal can selectively seal an annulus in the housing around a drill string extending through the first and second openings; a second flange comprising:\n a second mating face configured to mate with a flange of a second adjacent riser segment, and \n a second central flange lumen in fluid communication with the primary lumen; and \n a flow diverter permanently coupled to the second flange between the housing and the second flange, the flow diverter having a collar defining a lateral opening in fluid communication with the primary lumen, the collar having a collar lumen in fluid communication with the primary lumen, a main tube having a main tube lumen in fluid communication with the primary lumen, and a valve in fluid communication with the lateral opening, the valve having a longitudinal flow axis that is more parallel than perpendicular to a longitudinal axis extending through the first and second central flange lumens of respective first and second flanges.
