Abstract

Summary

Disturbing reservoir equilibrium by production or injection causes changes in saturation, pressure, and temperature, hence, substantial alterations on the stress state of a reservoir. In addition to vertical p-wave and s-wave velocity changes, the anisotropy parameters vary during production activities due to both pore pressure and saturation change. The anisotropic nature of stress-induced velocity change must be considered in 4D seismic analysis. Therefore, coupling fluid substitution with geomechanical modelling as demonstrated need to be considered. This work addresses the integrated modelling of 4D seismic response and how geomechanical stress direction calculation can be embedded in the petro-elastic modelling and fluid substitution.
