Riserless mud recovery (RMR™)
There's more to this concept than the name might indicate. Drilling without risers is not just an efficient way to make the top hole when seabed conditions complicate this initial phase of exploration drilling.
Just as unique, in an exploration drilling context is the system witch allows the operator to collect used drilling fluid and cuttings from the seabed and pump them back to the rig. This enables engineered fluids to be used as there are no discharges to sea. This also enables precise volume control to be implemented on the topholes. Combined, this will impact well construction.
A large number of successful drilling operations have proved our RMR technology to be a highly reputable and beneficial solution for drilling top holes in difficult seabed conditions, as well as reducing the conductor/casing strings. By using the RMS system operators have eliminated the use of 20" conductors, and successfully reached a setting dept of 13 5/8" casing down to more than 2350 meters depth. RMR - Zero discharges and cost-effective top hole drilling!
The RMR provides a number of benefits such as:
