Shell Selects Cameron's MARS Tech for First North Sea Application
Shell UK Limited has successfully installed the first of three subsea MARS (Multiple Application Re-injection System) interfaces on its Bittern field in the North Sea. The system has been described as a "USB port for wellheads" and is being adopted by Shell as part of their extended oil recovery (EOR) strategy for the region.
Following the successful commissioning, Shell is now able to complete reservoir stimulation / scale squeeze operations from a ROV support vessel without the need for MODU or diving support. The patented MARS system is a Cameron technology, supplied by DES Operations of Aberdeen.
"Until now operators have been using MARS for multiphase pumping and metering operations but this is a world first for reservoir stimulation," said Ian Donald, Managing Director of DES. "For Shell. MARS offers safer, faster and cheaper operations, with options to extend the functionality for further subsea processing operations."
The remaining two MARS systems are due for installation later this year and when installed will enable Shell to undertake multiple well stimulation campaigns from a single ROV vessel. "We approached DES two years ago to see if their technology could be adapted for our scale squeeze operations, and have worked with DES since then to this successful conclusion," said John Anthony, Shell Project Manager.
In addition to use in the Bittern field, MARS has also been successfully used by BP King in the Gulf of Mexico
and has been selected by Total for use in subsea multiphase metering in West Africa.
