Seismic Data Analysis Techniques in Hydrocarbon Exploration explains the fundamental concepts and skills used to acquire seismic data in the oil industry and the step-by-step techniques necessary to extract the sections that trap hydrocarbons as well as seismic data interpretation skills.
It enhances the ability to interpret seismic data and use that data for basin evaluation, structural modeling of a fault, reservoir characterization, rock physics analysis, field development, and production studies.
Understanding and interpreting seismic data is critical to oil and gas exploration companies. Arming young geoscientists with a reference that covers the key principles of seismic data analysis will enhance their job knowledge, skills and performance. A fundamental grasp of seismic data enhances employability and aids scientists in functioning effectively when working with seismic data in industry.
- Edited by a team of petroleum geoscientists with more than 30 years of experience in hydrocarbon exploration and data analysis at O&G companies.
- More than 200 figures, photographs, and illustrations aid in the understanding of the fundamental concepts and techniques used to acquire seismic data
- Takes an easy-to-follow, step-by-step approach to presenting the techniques and skills used to extract the geologic sections from acquired seismic data.
- Enhances the geoscientist’s effectiveness when using seismic data for field development and other exploration and production studies
Primary audience includes exploration geoscientists and seismologists in O&G. Secondary audience includes students at the upper undergraduate/graduate levels.

"…the book probably belongs on every beginning geophysical student’s bookshelf or at least in the department library...readers will gain an appreciation for the factors that might limit the accuracy of a seismic interpretation."--The Leading Edge, January 2015
“This book was recommended by my professor this semester for the course in Engineering and Exploration Geophysics and I must say - This is the best book I’ve seen around. The book talks to the reader. A job well done”. -- Jubril Davis, North Carolina State University, USA
"As far as exploration geophysics is concerned, it’s one of the best books I read in my life. The book covers in a very simple comprehensive manner, all geophysicist should keep in his library for reference. Expecting similar type of books in the future.” -- Vishnu Rajanbabu, Sr.Geophysicist/Seismic Interpreter at Reliance BP Exploration & Production Ltd, India
“This book would be a great benefit for all those concerned with seismic data analysis”. -- Mourad Wassef, CEO at Petromina Energy, Egypt
