Mapping Subsurface Structures – MSS
Not just a collection of rules of thumb, this class presents the fundamental concepts and techniques required to accurately construct structure maps in 3D so that you will get the most out of your data. Principles and techniques are illustrated by solving numerous exercises by hand (with drafting tools and a calculator) using strategies and workflows analogous to those that participants will use back at the office using computers. Participants will be prepared to develop more accurate structural models of reservoirs, avoid dry holes, find new traps in old fields, extract the maximum information from exploration wells, and validate or recognize errors in existing interpretations. Dr. Richard Groshong's book, 3D Structural Geology, is included with the course materials
"The course gave a very good basic understanding of structured geology as a whole. For me, not being a geologist, this helped a lot to clarify concepts, terms for my general career development." - Junior Geophysicist, Austria
"It is applicable to my job, especially the QC of the structural maps." - Exploration Geologist, United Arab Emirates

The course was well organized.
The course gave a very good basic understanding of structured geology as a whole. For me, not being a geologist, this helped a lot to clarify concepts, terms for my general care...
I really enjoyed to do the exercises. It was more easy to understand the theoretical part.
