Introduction to Petroleum Drilling

Target audience
The course is designed for personnel who work in the exploration industry but have little or no exploration-specific technical background. This includes administration staff, technical support staff, and those in management or professional roles whose background is in a field other than Earth Science.
The Drilling course is an ideal follow-up for those who have previously attended the Basic Exploration Short Course and would like a more detailed understanding of the drilling process. However, that is not a pre-requisite as both courses are entirely self-contained.

Course objectives:
The drilling of an oil well is seen as the culmination of the exploration process, but to the lay person it is a mysterious and complex undertaking which has a language all of its own. This course highlights the multi-disciplinary nature of the business, examines the tools and methods used in exploration drilling, and provides an understanding of the technical terminology and jargon used.
