SPE Talk on the Geomechanics of CO2 Sequestration

Updated: Mar 19, 2021

Along with three other geomechanics experts, PetroGem's Dr. Mehrdad Soltanzadeh will be delivering a talk about the geomechanics of CO2 Sequestration.

Principles and Challenges of Geomechanical Assessment of CO2 Storage Containment

Abstract: Injection of CO2 can compromise the sealing characteristics of the caprock and, hence, the containment of the stored fluid. Several of the attributes leading to this issue are related to the mechanical response of the rock to the low temperature and high pressure of the injected fluid.

This talk explores the principles of geomechanical assessment of caprock integrity through reviewing a variety of CO2 sequestration studies in Canada. These studies range from site selection for sequestrating in deep aquifers to its storage in depleted hydrocarbon reservoirs and CO2 injection for enhanced oil recovery. This presentation reviews different rock mechanical responses including stress change, deformation, and failure mechanisms to pore pressure and temperature change. It will also discuss application of pr

obabilistic and statistical analyses for considering the influence of uncertainty in geomechanical properties and modeling.
