Course Overview

Petrophysics is the study of physical and chemical rock properties and their interactions with fluids. While, core analysis is used to define not only the porosity and permeability of the reservoir rock, but also to unearth the fluid saturation and grain density. These petrophysical measurements help petrophysicist, reservoir engineers and other relevant professionals to understand the condition of the well and its productivity. During this course concepts of core preparation, core measurement, core analysis types and procedures will be explained. The petrophysical rock properties such as porosity, permeability, saturation and porosity-permeability relations will be studied. The relationships between these parameters under in-situ conditions will be discussed. The measurements and physics of well logging tools to methods for interpretation of these parameters will be applied. The understanding of well logging environments will be addressed. The trainer will provide the relationship between core analysis data and logging measurements for depth matching, understanding abnormal log readings and to obtain different petrophysical parameters. At the end of the course, the participants will be able to know core-log relations importance in solving or explaining many problems of logging measurement and rock properties. It is also important to define depositional and textural information, reservoir connate water, permeability and lithology.

Who is it for?

The course is designed for all professional with background and experience in petrophysics, whose job requires more extensive knowledge of core and log relations. They include petrophysicists, geologists, geophysicists, geoscientists, reservoir engineers, petroleum engineers and other E&P professionals.
