Reservoir Characterization

Reservoir characterization involves the detailed analysis of a subsurface reservoir’s properties, including porosity, permeability, fluid content, pressure, and geological structure. It integrates data from seismic surveys, well logs, core samples, and production history to build models that guide exploration, development, and production strategies.

Frequently Asked Questions

What data sources are used in reservoir characterization?

Common sources include seismic imaging, well logs, core samples, and production data. These inputs help geoscientists and engineers understand the reservoir’s geometry, fluid distribution, and flow behavior.

How does reservoir characterization impact well placement?

Accurate characterization enables optimal well placement by identifying high-quality zones with favorable flow properties. It reduces drilling risk and enhances recovery by targeting the most productive areas of the reservoir.

What role does reservoir characterization play in reservoir modeling of an asset?

Reservoir models simulate fluid flow and pressure behavior over time. These models are essential for forecasting production, understanding well interference, planning EOR strategies, and evaluating economic viability of development scenarios.

How is reservoir characterization evolving with technology?

Advances in machine learning, 4D seismic, and real-time data analytics are improving the precision and speed of reservoir characterization. These tools allow dynamic updates to models and better decision-making throughout the asset lifecycle.
