We provide the equilibrium.

Sentinel Subsea delivers the only technology to offer environmental assurance around suspended or decommissioned oil and gas wells. Thousands of wells are due to be suspended or decommissioned over the coming decades. The long-term integrity of those well barriers is critical.

Is there a risk of leakage and environmental damage? Yes.

Who is responsible? The well owner.

Each suspended or abandoned subsea asset is subject to an agreed inspection protocol, approved as part of an Environmental Impact Assessment.

Currently no industry standard monitoring procedure.

Sentinel Subsea has created a revolutionary, environmentally-friendly well integrity monitoring system. By passively monitoring the subsea environment for over ten years, without the requirement for intervention, it provides the decommissioning process with a solution which assures environmental integrity, multiple cost-efficiencies and no operational risk.

An environmental issue -
an eco-friendly solution.

Sentinel Subsea’s technology is a non-invasive, environmentally-friendly, risk-free and low-cost method of meeting optimum subsea asset inspection requirements.

Passively monitoring its environment for over 10 years, the in-situ technology comprises our unique, environmentally-sound chemical, a beacon and its trigger.

We repurpose material from the fish processing industry, which would normally go to landfill, and couple it with chemicals derived entirely from biomass. Sealed into a well at suspension or abandonment stage, this harmless substance will be released to the surface, should the well’s integrity be compromised even slightly. A beacon is then released to surface, where it is activated, producing an alert signal within five minutes of leak detection.


Why Monitor Abandoned Wells

Fast Action, Cleaner Environment: Current well inspection policy can specify a visual inspection every two years; the potential for a leak to remain undetected for some time is a likely potential scenario. Our in-situ technology provides notification as soon as the well loses its integrity. Subsequent remediation action, clean-up costs and financial penalties may therefore be considerably reduced.

  • Industry Reputation: The global oil and gas industry has encountered several well-documented environmental incidents. The resulting reputational damage – and the significant work required to counteract that - cannot be underestimated. Sentinel Subsea’s technology provides oil and gas producers with a straightforward means of demonstrating good environmental stewardship.
  • Driving Decommissioning Innovation: By monitoring well integrity, we provide the peace of mind to help advance decommissioning technology. Driving innovation and efficiency within the sector, our technology is helping to achieve the Oil and Gas Authority’s 35% decommissioning cost reduction target.
  • Reducing Carbon Emissions - Reducing Operating Costs: by replacing current ROV/AUV fly-by inspection with Sentinel Subsea’s passive technology, vessel time and cost is saved.
