Norske Conoco AS and Kvaerner Oil Field Products AS have developed a high-pressure composite drilling riser for field demonstration, which they believe is the world's first.

The digital twin gathers data from a series of sensors clamped at key joints along the riser string. The sensors were installed on the riser pipes using a remotely operated vehicle (ROV).

Each 75-ft. section of aluminum riser (top) weighs 31,000 pounds--33 percent less than the steel risers used on other rigs. A layer of high-density foam adds buoyancy, further reducing weight once ...

The 50 ft/15m long, 22 inch/55 cm ID joint was incorporated into the riser string while drilling three Heidrun live wells, at three different locations in the riser string — just above the stress ...

If there was ever a throwback trend in the drilling industry, Reelwell's riserless drilling method might be the key that opened the floodgates. The RDM-Riserless, as its name implies, drills ...

Robotic devices monitoring the deepwater well where a giant oil rig exploded and sank last week ... The oil was coming from two places in the riser — the 5,000-foot pipe that connects the well ...

Subsequently, the LMRP and the deployed riser string “unintentionally” separated from the rig at the slip joint tensioner ring, and the LMRP and riser dropped to the seabed.
