Extensional terranes provide some of the world's largest known and most prolific oil provinces and are the fundamental underpinning of most continental and deepwater margins. As one of the most common structural styles, they are present on all continents and form most continental shelves. The advent of 3D seismic technologies has revolutionized structural mapping, but the most realistic geologic interpretation of these structures is only as good as our ability to recognize and exploit the fundamental characteristics of the forms that are possible. This is the aim and purpose of this course. This course presents outcrop, subsurface, and seismic data along with model analogs to support structural interpretation in a wide range of extensional environments: thin-skinned environments along with the underlying, often hyperextended passive margins as well as intracontinental rifts. Fault linkage, relay ramp, transfer systems, and intrabasinal structural geometries are investigated in 3D using predictive kinematic and restorative thinking. The course covers the field level all the way up to basin-scale architecture, and the role of salt and strike-slip tectonics in the development of extensional basins. The typical traps related to extensional geometries are surveyed using real-world examples, with some review of deformational effects on reservoir quality. Exercises include typical seismic examples and field studies. The fundamentals of fracture dynamics are covered in connection with the evolution of extensional faults, as are such important topics as fault sealing issues and inversion. The instructor is happy to accept examples from your company for analysis in the class as one of the demonstration exercises. Please contact PetroSkills for a list of the information and support data required, as well as the necessary lead-time. The 3-day classroom course is followed by a 2-day field trip to the Death Valley area to reinforce the material from the classroom. "Now I see what they mean." - Geologist from Latin America, after the field trip "Good examples used that mostly fit what we see in the field." - Geologist II, United States "Liked fault geometrics and the structural restoration. I also appreciated fault linkages and traps in relay ramps and accommodation zones." - Participant, Nigeria |
Designed For: Exploration and development geologists, geophysicists, engineers, and managers responsible for the interpretation and drilling of extensional environments. |

Instructors: DR. JAMES W. GRANATH is a consulting structural geologist based in Denver, Colorado, who has worked in academia as well as the minerals and petroleum industries. Since 1976 he has taught at SUNY Stony Brook and spent 18 years in Conoco in research, international exploration, and new ventures. In 1999 he opened a consulting practice focused on structural geology and tectonics as applied to exploration problems, interrupted only by brief periods of work with Forest Oil and Midland Valley Exploration in Denver. He is a member of AAPG, AGU, GSA, and RMAG, and is a certified petroleum geologist (#5512) and a Texas Professional Geologist (#733). He is the author of numerous research papers and co-edited several multi-author compendia. His expertise lies in seismic interpretation and integration with structural analysis, fracture analysis, regional synthesis, and prospect and play evaluation. He holds his PhD from Monash University in Australia, and a BS and MS from of University of Illinois at Champaign-Urbana.
