Abstract
The identification of such strong compaction effect in case of poor consolidated formation should be utilize, with the definition of a compaction trend, in the evaluation and proper interpretation of seismic inversion output. As a result, we will get a reliable 3D lithology and formation properties distribution over the field. It will allow to create a reliable geological and reservoir dynamic models, to calculate in-situ and recoverable volumes of hydrocarbon accurately, optimize the field development plan.
Further integration of 3D geomechanical model and reservoir dynamic simulation allows to discriminate sediments natural compaction and compaction associated with reservoir depletion and their impact on reservoir properties and behavior such as porosity and permeability loss resulting in changes of flow rate.
