Petrophysics is the study of physical and chemical rock properties and their interactions with fluids. A key aspect of Petrophysics is measuring and evaluating rock properties by acquiring well log measurements. These petrophysical measurements help petrophysicist, reservoir engineers and other relevant professionals in reservoir characterization to identify productivity.

During this course, the basic concepts of petrophysical rock properties such as porosity and permeability and mineralogy will be covered. The relationships between these parameters and in situ fluid saturation will be discussed. Calibrate porosity andpermeability values from core and log sources for improved saturation calculation.

Understand and apply at a basic level the theory and operation of major well logging tools to methods for interpretation of these parameters will be applied. Apply basic cased-hole logging, borehole image, and LWD/MWD. Select petrophysical tool combinations for specific applications. The understanding of acceptable well log data will be addressed.

This course is prepared to provide the basic interpretation, concepts and fundamentals on which to develop the petrophysical knowledge and capabilities necessary for geologists, geophysicist, engineers and beginner petrophysicist. Assess the impact of petrophysical analyses on technical uncertainty estimates of reservoir. Analyze and integrate log, core, geoscience and engineering well data for well and field development projects.
