Abstract

​

The paper presents the steps for running a geomechanical model for steam injection modeling. Two types of rock integrity failure are analyzed: tensile and shear failure. In the present case, shear failure of cap rock occurs after 40 months of steam injection. Such failures should be taken into account in subsequent reservoir simulation modeling through coupling the geomechanical and reservoir simulation models.

Key words:

​

maximum steam injection pressure, rock damage, thermal-hydraulic-mechanical model, land surface displacement, shear failure, tensile failure
