Technology has been predicted as the last card in combating the ever increasing demand of our commodity; oil and gas. Since the core technique used in exploring for Oil and Gas is the Reflection Seismology; then, modern approach to Seismic data acquisitions and interpretation is of prime essence. A powerful, unconventional Interpretation tool; Spectral decomposition, has been used to visualize (in 3 – D) a thin sandstone reservoir in “X – Field” Niger Delta, Nigeria. The study aimed at mapping thin sandstone beds which have been considered sub seismic or un-mapable using conventional interpretation methods. The suite of Well log data and seismic data were acquired and qualitatively and quantitatively interpreted using RocDok and OpendTect software. The identified thin beds were delineated perfectly using the spectral decomposition tool which was portrayed through amplitude variations. However, new hydrocarbon prospects were identified through similarities of amplitude signature.

This book introduces readers to the field of seismic data interpretation and evaluation, covering themes such as petroleum exploration and high resolution seismic data. It helps geoscientists and engineers who are practitioners in this area to both understand and to avoid the potential pitfalls of interpreting and evaluating such data, especially the over-reliance on sophisticated software packages and workstations alongside a lack of grasp on the elementary principles of geology and geophysics. Chapters elaborate on the necessary principles, from topics like seismic wave propagation and rock-fluid parameters to seismic modeling and inversions, explaining the need to understand geological implications. The difference between interpretation of data and its evaluation is highlighted and the author encourages imaginative, logical and practical application of knowledge. Readers will appreciate the exquisite illustrations included with the accessibly written text, which simplify the process of learning about interpretation of seismic data. This multidisciplinary, integrated and practical approach to data evaluation will prove to be a valuable tool for students and young professionals, especially those connected with oil companies.

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

This book demystifies that art and science of seismic interpretation for those with and without formal geophysical training. From geologists to managers and investors, The Art and Science of Seismic Interpretation is a guide to what seismic data is, how it is interpreted, and what it can deliver.

Over the past several years, there has been a growing integration of data – geophysical, geological, petrophysical, engineering-related, and production-related – in predicting and determining reservoir properties. As such, geoscientists now must learn the technology, processes, and challenges involved within their specific functions in order to optimize planning for oil field development. Applied Techniques to Integrated Oil and Gas Reservoir Characterization presents challenging questions encountered by geoscientists in their day-to-day work in the exploration and development of oil and gas fields and provides potential solutions from experts. From basin analysis of conventional and unconventional reservoirs, to seismic attributes analysis, NMR for reservoir characterization, amplitude versus offset (AVO), well-to-seismic tie, seismic inversion studies, rock physics, pore pressure prediction, and 4D for reservoir monitoring, the text examines challenges in the industry as well as the techniques used to overcome those challenges. This book includes valuable contributions from global industry experts: Brian Schulte (Schiefer Reservoir Consulting), Dr. Neil W. Craigie (Saudi Aramco), Matthijs van der Molen (Shell International E&P), Dr. Fred W. Schroeder (ExxonMobil, retired), Dr. Tharwat Hassane (Schlumberger & BP, retired), and others. - Presents a thorough understanding of the requirements of various disciplines in characterizing a wide spectrum of reservoirs - Includes real-life problems and challenging questions encountered by geoscientists in their day-to-day work, along with answers from experts working in the field - Provides an integrated approach among different disciplines (geology, geophysics, petrophysics, and petroleum engineering) - Offers advice from industry experts to geoscience students, including career guides and interview tips

This book is the published record of the papers presented at a conference of the Norwegian Petroleum Society (NPF) held in Bergen, Norway, on 3-5 October, 1988. The conference was initially proposed and promoted by the Geology and Geophysics Advisory Committee of the Norwegian Petroleum Society consisting of: A. M. Spencer (Chairman), M. Brink,J. D. Collinson, S. Hanslien, D. M. D.James, T. B. Lund, K. Messel, E. Ormaasen and G. Saeland. The programme and more detailed planning of the conference was carried out by a programme committee consisting of: J. D. Collinson (Chairman), O. Eldholm, E. Holter, D. M. D.James, H. Tykoezinski, D. Worsley and S. M. Aasheim. There were 245 participants at the meeting and 36 papers were presented as talks with a further 9 presented as posters. These proceedings are representative of the range of topics covered. The meeting was characterized by a high level of discussion which has influenced several authors in the final preparation of their written papers. These proceedings have been edi ted on behalf of the Norwegian Petroleum Society by J. D. Collinson with help from H. Tykoezinski. The editor and the organizing committee wish to thank all the referees who reviewed papers and all the authors who responded so fully and promptly to their comments. The NPF is most grateful to the University of Bergen for making available their facilities for the conference.
