Effects of impurities on geological storage of CO2

1st July 2011

Topic(s): Carbon capture, use and storage (CCUS), CO2 storage, CO2 utilisation

This study provides a review of existing information and published research on the potential impact of CO2 waste stream purity on storage engineering and associated costs. A range of storage scenarios are considered, including deep saline aquifer formations, depleted gas fields and CO2-EOR schemes, although the study focuses primarily on deep saline formations since this scenario has the largest theoretical storage capacity and the most significant potential for complex geological reactions.

Particular aspects considered include:

  • the potential effects of impurities on behaviour and storage capacity calculations;
  • effects on the rate of geochemical reactions with both formations and caprock associated buoyant forces and trapping mechanisms;
  • potential effects on injectivity, reservoir permeability and caprock integrity both near well-bore and deeper in the formation; and
  • potential for corrosion of well components and estimated impacts on system reliability if not mitigated.
