Discipline: Petrophysics
Level: Basic
Duration: 5 days
Instructor:Jesus Sotomayor


Petrophysics is fundamental to all aspects of the petroleum business. Principles, applications, and integration of petrophysical information for reservoir description will be discussed in depth. Through a combination of class discussion and exercises, participants will learn how to conduct competent quick-look evaluations. Using data from open hole logs, logging while drilling, and core data you will evaluate porosity, permeability, and saturation in a variety of reservoirs. Knowing how to integrate petrophysical information with other data sources will improve participants ́ ability to assess technical risk when examining hydrocarbon opportunities.


Beginners geoscientists and engineers using petrophysical data and other technical staff at all experience levels wanting a fundamental background in the petrophysical discipline.
