Impact of injected CO2 on reservoir mineralogy during CO2-EOR
An investigation of the impact of injected CO2 on reservoir mineralogy was completed as part of the geochemical monitoring and modelling of the Pembina Cardium CO2 Monitoring Project southwest of Drayton Valley, Alberta, Canada.

An investigation of the impact of injected CO2 on reservoir mineralogy was completed as part of the geochemical monitoring and modelling of the Pembina Cardium CO2 Monitoring Project southwest of Drayton Valley, Alberta, Canada. Oil production at the pilot is primarily from the upper two of three stacked sandstone units of the Cardium Formation in the Pembina field. Core analyzed included samples from each of the three sandstone units, and encompassed three distinct time periods: pre-water flood (1955), pre- CO2 flood (2005), and post- CO2 flood (2007).
