GL5045: INTRODUCTION TO PETROPHYSICS AND ITS ROLE IN THE OIL AND GAS INDUSTRY (2018-2019)

Last modified: 22 May 2019 17:07


Course Overview

Petrophysics is fundamental to understanding the properties of hydrocarbon fields both for initial static volumes in place and potential and actual dynamic performance. It lies at the centre of all subsurface activities, whether in the context of open-hole evaluation of new wells, cased-hole operations on producing wells, or in an integrated team building reservoir models for asset evaluation, field development or reservoir management. The key aims of this course are to teach: the principles of petroleum exploration, development and production to staff entering the industry for the first time, and enough basic understanding to perform a simple reservoir evaluation.
