Introduction
Integrated petrophysics is a core discipline in understanding oil and gas reservoir characteristics. It connects well data, core analysis, log interpretation, geological information, and engineering inputs to build a reliable view of reservoir quality and production potential. Effective reservoir evaluation depends on interpreting data as a connected system rather than treating each data source separately.
This course focuses on integrated petrophysics for reservoir evaluation through a practical and structured approach. It explains how to analyze rock and fluid properties, interpret well logs, estimate porosity, saturation, permeability, and shale volume, and evaluate hydrocarbon-bearing intervals. The course also highlights the importance of integration between petrophysics, geology, reservoir engineering, and production in supporting technical decisions related to reservoir development and optimization.
The course is structured over five days in a strong and logical sequence. It begins with the technical foundations of petrophysics and reservoir evaluation, then moves into log interpretation, rock property analysis, saturation and fluid evaluation, integrated petrophysical modeling, and a final integrated application based on a practical reservoir case.
