Introduction to Petrophysical Interpretation


About the Skill Module

This skill module introduces the Petrophysical Interpretation of Unconventional Reservoirs. Sources of information for reservoir description are covered and include hydrocarbon generation as a function of temperature and composition, wellsite data, coring, and core analysis, well logs, and dynamic testing. Organic-rich shales can be naturally enhanced beyond the initial porosity and permeability. Methods of enhancement and examples are provided.

Commonly used petrophysical models for volumetric assessment and reservoir quality are presented. Geomechanical properties can be calculated from cores and well logs and are introduced.

The content is suitable for anyone wanting to understand the bases for subsurface resource estimation of organic shales. Previous exposure to subsurface terminology and concepts is assumed.
