Laboratory Measurements of Basic Rock Mechanical Properties
About the Skill Module
Laboratory testing is considered one of the most reliable sources for characterization of mechanical rock properties. This skill module provides a profound understanding of the laboratory tests commonly conducted in the practice of petroleum geomechanics. It explains how to efficiently understand, interpret, and use the results of these tests in geomechanical workflows.
Target AudienceGeoscientists, petrophysicists, completion and drilling engineers or anyone involved in unconventional reservoir development
You Will Learn
Participants will learn how to:
