Relief Well technology

Trendsetter Engineering and Add Energy have combined expertise to provide engineering and hardware support services to the industry’s most challenging problems in a nimble and responsive environment. The companies have recently been awarded a contract to supply engineering expertise and access to Trendsetter’s patented Relief Well Injection Spool (RWIS) in support of an operators’ drilling campaign on a newly sanctioned field development.

The RWIS has been designed and built to greatly increase the pumping capacity of a single relief well by enabling the ability to pump in excess of 200 bbl per minute of kill mud through a single relief well, utilising multiple vessels as opposed to the conventional method of multiple relief wells. The RWIS is installed on the relief well wellhead beneath the blowout preventer (BOP) to provide additional flow connections into the wellbore. Using high-pressure flex lines, the inlets enable pumping units from separate floating vessels, in addition to the relief well rig, to deliver a high-rate dynamic kill.

Morten Haug Emilsen, Senior Vice President at Add Energy noted: “The RWIS technology has a huge cost saving potential that enables larger completions and optimised casing design.”
