Sentinel Subsea is a technology company specialising in monitoring the integrity of oil & gas wells.

In contrast to traditional methods, our in-situ technology provides continuous real-time well integrity monitoring even in the most remote subsea environments.

Our low-cost, easy to deploy and environmentally friendly well monitoring systems let well operators comply with regulatory inspection requirements without the need to schedule vessel based subsea inspection.

Sentinel Subsea’s solutions can be applied to any well throughout its life cycle.

Cost efficient environmental stewardship is the foundation of a thriving, 21st century energy industry.

Sentinel Subsea holds the key.


Sentinel Subsea has a range of systems that are easily installed subsea and require no active power source. Our systems are configured to suit differing well requirements:

Hydrocarbon Detection System. Our detection systems are installed subsea in order to capture the typical gas (C1 –C5) and/or fluid hydrocarbons that emanate from a subsea well should there be a loss of containment. Once hydrocarbons are detected they degrade our proprietary locking material, this mechanism releases an alert beacon to surface.

Tracer Detection System. Our tracer detection systems work by in a similar way to the HDS but rather than detecting well hydrocarbons, the system monitors for our Tracer Fluid (SWIFT). SWIFT is simply sealed in a shut-in or suspended well, and will only enter the subsea environment should there be a loss of containment.



Our unique technology brings a number of fundamental benefits to well operators, ensuring optimum environmental safety, lower monitoring costs, and reduced risk from exploration to final abandonment.

“…the value this technology will bring is multi-faceted. It negates the need for annual or biannual inspections - an important contribution to lowering costs. Operators have the confidence to deploy some of the alternative abandonment technologies, knowing that should there be an issue it would be caught early, and remediation would be simpler and cheaper.”― The Oil & Gas Technology Centre
