DiSECCS Project

Carbon

Diagnostic Seismic toolbox for the Efficient Control of CO2 Storage (DiSECCS)

 

The project is led by NERC British Geological Survey and will bring together monitoring datasets from the world's three industrial scale CO2 storage sites at Sleipner (offshore Norway), Snohvit (offshore Norway) and In Salah (Algeria) to develop and test advanced and innovative monitoring tools and methods for the measurement and characterisation of pressure increase, CO2 migration and fluid saturation changes and geomechanical response.

Overall project objectives

 

Induced pressure increase in storage reservoirs, might, in certain circumstances, have the potential to produce significant seismicity and reduce containment integrity. This is a potentially serious issue as it would impact directly on storage integrity and, by extension, would reduce the number of reservoirs that are suitable for large-scale storage. Viewed strategically this could impact on government climate change and energy policy because it has the potential to significantly reduce national storage capacity inventories.

The principal high-level objectives of DiSECCS therefore are as follows:

  • To develop monitoring tools and protocols to predict, measure, characterise and control pressure increase, induced seismicity and geomechanical stability in storage reservoirs.
  • To identify the spectrum of reservoir types that, with appropriate characterisation and monitoring, are suitable for large-scale storage without unwanted geomechanical effects.
  • To further improve detailed understanding of storage processes to help optimise storage in suitable reservoirs and maximise their storage capacity.
