Basics of Geology, Geophysics & Petrophysics for Engineers and Other Disciplines
En español/Spanish version
Course overview
This course covers basic concepts, principles and applications of geology, geophysics and petrophysics as applied today in the E&P business at an awareness to knowledge level. This course, available in 3 or 5 day forms, provides an overview treatment of the role of Geoscience in exploration, exploitation design and production of hydrocarbon resources. This course focuses especially on what in geology, geophysics and petrophysics is important to drilling, production and reservoir engineers and others who work on or with integrated E&P teams in today’s industry environment. Emphasis is placed on the fundamental principles, business value and practical applications of Geoscience disciplines not detailed theory, using case histories and examples/exercises as appropriate. This course can be customized for specific needs of clients.
The course is designed for
Business professionals other than Geoscientists in the Oil & Gas Industry, who wish to understand the principles of the main Geoscience disciplines, and their applications in today’s E&P industry. The course is also appropriate Geoscience new hires. Attendees should have already completed a Basic Introduction to E&P Industry.
