Basic Petroleum Geology - BG - Blended, Virtual Delivery


About the Course

This course is designed to introduce anyone to the basic concepts of Petroleum Geology. An important goal of the course is to explain the vocabulary and context of Petroleum Geology so that participants can learn and understand the role of the Geologist in the overall process of Petroleum Exploration and Production, for both Conventional and Unconventional Resources. The course is supplemented by a large number of case histories and examples that concretely illustrate the concepts and principles presented in the course material.

This program is comprised of the PetroAcademy Skill Modules listed in the Course Content section. Each module ranges from 3-5 hours of self-paced or virtual instructor-led activities.

Target Audience

Petroleum industry personnel in need of basic geological training, including engineering, geophysical, technical support, and administrative personnel.
