MPD Riser Integration Joint

Oil States compact Managed Pressure Drilling (MPD) Riser Integration Joint (RIJ) has been designed to improve safety and increase operational efficiency.
Oil States joint is around half the length and up to 1/3rd the weight of conventional RIJ's, making it easy to handle and fast to rig-up. Hands-free flow line and umbilical stabbing removes the need for man-riding.
Being fitted with twin retrievable stripper packers and bearing assembly, the joint is completely serviceable whilst over well center. Stripper packers are run and retrieved by drill pipe tool removing the need to pull the RIJ from the string or return to the onshore service center to replace annular seals.
