Shell is continuing its relationship with AGR’s riserless mud recovery (RMR) system with a new $4.7m (£3m) deal.
The contract is for multiple development wells on Shell’s Prelude Floating LNG development off Australia’s north-west coast.
The contract is for three years with the option of two one-year extensions.
RMR allows engineered mud to be used in the top-hole section of a well, enabling a much more stable foundation for successful drilling, with all mud and cuttings being returned to the rig. There is no discharge to the seabed.
