Abstract

A unified approach for mechanical compaction modeling in clastic basins is presented. The modeling approach is consistent with natural strain increment formulation often used in plasticity theory. Laboratory and field estimates of constitutive plastic deformation relations for sand-shale mixtures are used in a numerical model that generates estimates of porosity in 3D under various pore pressure, shale content, and loading scenarios. These estimates can be used in a variety of settings to predict various basin and reservoir properties associated with different loading conditions and/or sedimentation processes.
