"Performance-Based Reservoir Characterization of Unconventional Reservoir Systems"

Model-based well performance analysis and forecasting has become quite popular in recent years; however it is a challenging task due to the low/ultra-low permeability nature of unconventional reservoirs as well as to the complexity (e.g., geology, PVT, etc.).  Advanced models, which could account for non-linearities such as multi-phase flow/complex PVT, stress dependent properties, are required for more robust analysis and forecasting.  However, it is practically impossible to analyze and forecast each well using the advanced models in a developed field due to time constraints.  The focus of this presentation is to demonstrate a practical methodology, which is efficient in terms of time constraints, and sufficient to incorporate complex flow behavior, for the analysis and forecasting of producing wells in a particular area/field in an unconventional reservoir.  Results of this workflow could provide insights in terms of establishing reservoir management strategies and provide recommendations on field development.
