The Mechanical Impact of CO2 Injection

A019 Abstract The mechanical impact of CO2 injection 1 B. ORLIC B. SCHROOT Netherlands Institute of Applied Geoscience TNO – National Geological Survey PO Box 80015 3508 TA Utrecht The Netherlands. The mechanical impact of CO2 injection into a depleted hydrocarbon field or aquifer is caused by changes in the stress field resulting from changes in the pore pressure and volume of the rock. Mechanical processes can lead to the loss of reservoir and caprock integrity and the reactivation of existing faults. A geomechanical numerical modelling approach to determining the mechanical impact of CO2 injection is presented and demonstrated on
