Total Oil Recovery Technique

Page last modified
February 22 2024

TORT offers non-invasive recovery of attic oils and similar for cleaning and decommissioning operations.The system uses a lightweight fluid for oil displacement. This fluid can be pumped directly from reservoir tanks or batched between Aubin EVO-Pigs to deliver the fluid in an efficient manner reducing overall total volumes used during de-oiling/de-cruding.

As an immiscible fluid, TORT does not mix with the recovered oils allowing for easy separation and recovery/processing.

TORT has been deployed by a Global Operator and Global Service Company, operating in the North Sea.
