Structural Styles and Fracturing in Compressive Basins

Dr. Shankar Mitra
Descripción del instructor

Holds the Monnett Chair and Professorship of Energy Resources at the University of Oklahoma. He received his Ph.D. degree in Structural Geology from Johns Hopkins University in 1977. He spent 19 years at ARCO Research and Exploration as Senior and Principal Research Geologist, Director of Structural Geology, Manager of Geological Research, Exploration Director, and Senior Exploration Research Advisor. His primary interests are in the development of structural concepts and methods and their application to exploration and production problems. He was an Associate Editor of the A.A.P.G. Bulletin for 9 years. He is a two-time recipient of A.A.P.G.’s Wallace Pratt Best Paper award and the Cam Sproule Best Paper award.

ABOUT COURSE

 

COURSE OBJETIVE

Compressive structural provinces contain complex trap-forming structures, which are not well imaged on seismic data. The objective of the course is to discuss the use of 2-D and 3-D structural models and techniques for constructing maps, seismic interpretations, balanced cross sections and 3-D interpretations. Controls of structural styles on fracture potential will also be discussed. Models of trap-forming structures for fold-thrust belts, foreland basement structures, and inversion structures will be presented. Numerous examples of productive structures from compressive basins will be discussed. Problem sets will provide hands on experience in interpreting subsurface structures using seismic and well data.

 

WHO SHOULD ATTEND

Exploration and Production Geologists and Geophysicists. The course is designed for geoscientists working in complex Compressive structural provinces, who need to apply structural models and 2-D and 3-D structural methods to improve structural and seismic interpretations and evaluate fracture potential for prospect evaluation and field development.
