CNOOC International has signed a contract to use Enhanced Drilling’s RMR® Riserless Mud Recovery system for two of the wells on the Golden Eagle Development project in the North Sea.

Zero emissions drilling technology

The recent contract with CNOOC International includes the provision of top-hole RMR® Riserless Mud Recovery services for the duration of the Golden Eagle 2022 development campaign with work due to commence in July 2022. Enhanced Drillings’s RMR® technology eliminates pumping and dumping liquid and waste to seabed, hence, there is zero discharge of chemicals and cuttings during the drilling process.

The RMR® system creates a closed mud system even when drilling riserless, meaning the operator will have full volume control during the riserless drilling. The system will collect all fluids coming out of the well and return it to rig without losing mud or contaminating the mud with seawater. This means that any changes of flow out of the well will be monitored, and any losses and gains will be discovered immediately.

‘Thrilled to be chosen as CNOOC’s partner’’


Everyone operating in the North Sea shares a common goal to achieve a significant reduction of greenhouse gas emissions by 2030, and net zero by 2050.  The zero discharge RMR® Riserless Mud drilling technology can contribute to the path towards Net Zero in 2050, and

"We are thrilled to have been selected by one of the world’s largest energy companies”,

said Bernt Eikemo, VP Sales & Marketing at Enhanced Drilling.
