AGR to provide RMR drilling services offshore Sakhalin
An unnamed operator has contracted AGR Enhance Drilling to provide riserless mud recovery (RMR) services this summer offshore Sakhalin Island, eastern Russia.
Drilling operations in the designated area include challenging top-hole conditions and stringent environmental regulations, AGR says.
RMR allows use of weighted mud during top-hole drilling. All mud and cuttings are returned to the rig, without discharge to the sea – this is said to lead to a more stable top-hole, drilled with minimal environmental impact.
