Poromechanics Modeling Forecasts Production, Analyzes Productivity Decline

This paper describes a full-field and near-wellbore poromechanics coupling scheme used to model productivity-index degradation against time.

Full-field model and wellbore model coupling. The top plot is the full-field reservoir model with 12 wells; the bottom plot is the detailed half-well model. A full-field model can be coupled with multiple wellbore models.

Productivity index (PI) decline is caused by different mechanisms in both the wellbore region and the far field. Damage in the wellbore region can be simulated by detailed wellbore modeling. A newly developed full-field and near-wellbore poromechanics coupling scheme is used in the complete paper to model PI degradation against time. Near-wellbore damage and field and well interactions are identified when applying the coupling scheme for a deepwater well.
