Carbon Capture & Storage (CCUS) – Rig INSPECTION

ADC Energy Ltd. Carbon Capture Semi Submersible



Carbon Capture, Utilisation and Storage (CCUS) , will undoubtedly be a vital part of reducing global greenhouse emissions. Thus the use of previous exploited and now depleted oil and gas wells presents a potential CO2 storage solution.  Drilling rigs and specialist vessels will therefore be integral to enabling this solution.

Drilling Rigs and specialist vessels are required during the following CCUS project phases:

  • Exploration & Appraisal Phase
    • Drilling exploration wells to provide input into studies to determine storage site suitability.
  • Development Phase
    • Drilling wells for CO2 injection and, in some cases for saline aquifers, brine pressure release wells.
    • Specialist vessels e.g. for the installation of pipelines and cables.
  • Operations and Maintenance Phase 
    • Potential requirement for rigs to be used to work-over injections wells, as well as drill intervention wells in the event of well leakage. 
  • Decommissioning Phase 
    • Drilling Rigs or Well Intervention Vessels for operations such as Well plugging and abandonment.  


Drilling Rig and Vessel Operational Assurance 

ADC recognise the drilling rig is more often than not the largest project cost item for our clients. The risks of un-planned downtime or unexpected safety issues are significantly reduced by proactively identifying risks through systematic rig inspection.

Our belief is that such an investment should be evaluated to the highest possible standard given the potential financial risks and commercial exposure rig downtime can present.
