Basic Petroleum Geology

Objectives

This course provides an introduction to petroleum geology and operational and wellsite geologi-cal procedures. Delegates will be instructed in the physical and chemical properties of the major sedimentary rocks and will be able to examine hand specimens and drill cuttings of all the major rock types. The origin, migration and trapping of hydrocarbons is covered together with a review of key sedimentary and geological features such as folding and faulting. The effect of geology on key drilling practices such as mud systems, bit selection and performance and directional drilling is also discussed. The course is highly practical, includes a comprehensive manual and is pre¬sented in an informal style to promote maximum participation and discussion.
