TOTAL E&P Australia (Total) has signed up to use AGR’s Riserless Mud Recovery (RMR®) system.
The contract is for two exploration wells to be drilled over the next year in the Browse Basin off North West Australia.
Bernt Eikemo, AGR’s Vice President of the Enhanced Drilling Solutions (EDS) division (Asia Pacific), said: “AGR is delighted to be part of Total’s drilling team during the forthcoming exploration campaign. We hope that this is the start of a long, successful relationship with Total E&P Australia.”
He added: “Our previous experiences with several operators in the Browse Basin and the North West Shelf have shown that unconsolidated sand formations become much more benign when drilled with RMR® using a proper mud system.”
RMR® has been used by Total on several other projects internationally but this is the first time that the operator has used the system in Australia.
The main reason for using RMR® on these wells is to be able to drill through the unconsolidated sands of the Grebe Formation. It is renowned for stuck-pipe problems when drilling riserless using seawater and sweeps.
RMR® enables the use of weighted, engineered mud in the top-hole section. All mud and cuttings are returned to the rig with no discharge to the seabed. The top-hole section can be drilled more safely, quickly and with less impact on the environment.
RMR®, together with its sister technology the Cutting Transportation System (CTS™), has been deployed on more than 500 wells worldwide to date.
