Introduction

Reservoir Characterization & Modeling (RCM) is a fundamental discipline in petroleum engineering and geoscience that integrates geological, geophysical, petrophysical, and engineering data to develop a comprehensive understanding of subsurface reservoirs. Effective reservoir characterization enables organizations to reduce uncertainty, optimize field development plans, improve hydrocarbon recovery, and support informed decision-making throughout the asset lifecycle.

As reservoirs become increasingly complex, accurate characterization and modeling have become essential for understanding reservoir architecture, fluid distribution, rock properties, connectivity, heterogeneity, and production behavior. Modern reservoir studies rely on integrated workflows that combine multiple data sources to create realistic subsurface models capable of supporting drilling, completion, production, and reservoir management strategies.

This course provides participants with a structured understanding of reservoir characterization and modeling principles, methodologies, and applications. Participants will learn how geological, geophysical, petrophysical, and dynamic reservoir data are integrated to build static and dynamic reservoir models that support field development and production optimization.

The program combines theoretical foundations with practical industry applications, enabling participants to understand the complete reservoir modeling workflow from data acquisition and interpretation through model construction, uncertainty analysis, simulation support, and field development planning.
