Seismic QI: An End-User's Guide
Description
This book offers a practical guide to quantitative interpretation (QI) products for reservoir modelling and uncertainty analysis. Its content and format make it accessible to readers with and without a geophysical background.
Understanding the geological meaning, or meanings, of the seismic response can be challenging, especially in unexplored or under-appraised areas. It falls to geologists and reservoir modellers to integrate the seismic response and geological data into reservoir models, prospect evaluations and uncertainty analysis. The authors provide these end-users with a guide on how to extract the most value from QI products and incorporate them into reservoir models; further, they illustrate how to translate QI results into meaningful inputs for common, and not so common, modelling workflows.
After a concise and accessible introduction to rock physics, the book provides an overview of a range of inversion techniques used in the industry, and presents real-world examples capturing the highs and lows, benefits and limitations. This gives end-users the tools they need in order to play an active part in all stages of the QI workflow.
This book will benefit all geologists, reservoir modellers, technical professionals working in integrated sub-surface teams, and non-technical experts who need a sound grasp of QI techniques in order to evaluate commercial decisions based on their outputs. Advanced students of petroleum geology will also find this book of interest.

Persons
Dr Mark Bentley has been in the oil and gas industry since 1986, initially as a production geologist with Shell, working in the UK, Oman (PDO) and the Netherlands and subsequently training and consulting with TRACS (now owned by AGR Petroleum Services) based in Scotland. He has spent most of his career working in or leading integrated study teams on a wide variety of reservoir assets. His specialist technical fields of expertise are 3D reservoir modelling and scenario-based approaches to handling subsurface uncertainty and risk, including the associated behavioural heuristics, and he is the co-author of the textbook 'Reservoir Model Design' with Prof Philip Ringrose. He has written and delivered tailored training courses for International and National Oil Companies on every continent except Antarctica.
Dr Peter Rowbotham is a quantitative geophysicist with over twenty years of experience with Elf, Shell, AGR TRACS and currently Apache in Aberdeen. His specialist skills lie in Quantitative Interpretation areas, such as AVO, 4D and seismic inversion. In the last decade he has also led integrated subsurface teams for studies and drilling operations, training and performing operational geophysics. Although based in the UK, he has worked with marine seismic data throughout the North Sea/West of Shetlands, Africa and South America, and onshore seismic data from Europe, the Middle East and North Africa.
Dr Liz Chellingsworth is a geoscientist with sixteen years' experience in the oil and gas industry, initially working for Hydrosearch, Fugro and ffA and for the last ten years with AGR TRACS. She has a strong background in geophysics and geology and has worked as a project manager and geoscientist on a range of projects from exploration and appraisal through to development. Her key skills areas include seismic attribute analysis, integrating geophysical and geological data for reservoir modelling, prospect evaluation and play fairway mapping, as well as Risk and Uncertainty assessment. Dr Chellingsworth also teaches classroom and field-based courses on topics such as Seismic Attributes, Risk and Uncertainty and Reservoir Modelling for the training division of AGR TRACS.
