CO2 monitoring platform

Our vessel-based installation system and process provides a simple and low-cost way of installing the fibre optic bore hole arrays.

We provide the power and telemetry platform for 3rd party fibre optic seismic sensors and interrogators.

Seismic surveys can be performed prior to CO2 injection at the storage site to present a baseline understanding of how the site performs.

Repeat seismic surveys can be performed to track the CO2 plume within the formation, throughout the injection process and after it has ceased.

It is then possible to review seismic data to track the plume as it migrates through the formation.

Measurement data is collected, confirmed,  and then sent back onshore via a satellite or mobile network where scientific data analysis reviews can  take place against the baseline plan.

If the CO2 plume is not migrating through the formation as planned or enters weak spots at higher concentrations than expected, injection rates can be adjusted or stopped whilst the situation is investigated.

Prior to our subsea sensor array being deployed, a pre-site survey and baselining will be conducted to determine the current levels of dissolved gasses, currents and seasonal variations at the site.

Using an engineered solution based on the subsea sensors’ continual monitoring takes place. The baseline ensures any changes are due to a leak rather than seasonal fluctuations.

Sensors can detect and measure low levels of dissolved gas combined with other data points (or sensors such as PH) to determine the magnitude and location of a leak to the water column.

Collected data is then sent back onshore via a satellite or mobile network where an automated scientific data analysis review takes place.

If a leak is detected, a lightweight fast boat/ROV mounted additional sensor can be deployed to further investigate and diagnose any alert prior to instigation of leakage solution.
