An introduction to: velocity model building




Ian Jones

This book sets-out to give the reader a non-mathematical understanding of the basic principles of migration and of building a velocity model of the earth's subsurface. The intended readership includes anyone who has to work with, or to understand, how contemporary seismic images are created: what are the underlying principles and pitfalls? How is a velocity model typically built and what are the consequences of not getting it right? Concepts such as uncertainty and non-uniqueness are discussed as are the ways in which these topics translate to risk-reduction and reliability in the final image. The different ways of representing a velocity model are reviewed as are the techniques used for picking velocity and anisotropy related information. A review of the principles of tomography is presented, to familiarize the reader with the techniques that underpin all contemporary velocity model update. Also, the physics behind anisotropy and its consequences for obtaining images in ?true? geological depth are discussed. An historical overview of velocity model building techniques over the past 30 years is presented to give the reader a feel for how the black art of model building has evolved in tandem with the increase in computer power and the emergence of powerful interactive graphics, covering the evolution from a purely linear compartmentalized industrial process towards a fully interactive multidisciplinary approach to iteratively building a reliable subsurface velocity model. The book concludes with a look at emerging and future trends: the promise of velocity-independent imaging and the potential of full waveform inversion.

From seismic interpretation to modelling and assessment of o




Yury Ampilov

In this publication the author pays special attention to the cross-disciplinary problems of the geosciences: seismic processing and interpretation, geological and hydrodynamic modelling and he analyses the contradictions of the applied methods. The author states that narrow specialization in geosciences has hindered unbiased subsurface investigation. There is a need for new specialists who are able to integrate knowledge from the different fields. The book provides critical but unbiased analysis of the interpretation possibilities of seismic exploration when forecasting rock properties. Moreover, compared to the Russian version, this edition gives a more extended analysis of seismic inversion algorithms. This book will be useful for geologists, geophysicists, engineers involved in the development of hydrocarbon fields and other, cross-disciplinary specialists.

Integrated geophysical models




Paolo Dell'Aversana

The growing interest for electromagnetic and gravity methods, together with the availability of high quality seismic data, justifies the development of efficient methodologies for combining heterogeneous geophysical information into multi-parametric models. This book discusses different approaches for building integrated geophysical models using seismic, electromagnetic and gravity data. The book will focus mainly on land and offshore geophysical data acquired at the surface. However, also borehole data will be considered as a fundamental support for geophysical integration. Integrated acquisition techniques will be included in the discussion, but the focus will be mainly on integrated model building. Target audience: a) Exploration geophysicists and geologists b) Reservoir geophysicists, petrophysicists, geologists, engineers c) Exploration and reservoir managers d) Academics dealing with seismic and/or non-seismic methods e) Students and researchers in geology and geophysics Integrated geophysics is one of the most important problems in geosciences. In fact it has received considerable attention in the technical literature since about 1960. However it is difficult to find books dealing with a comprehensive discussion about quantitative integration of the most recent seismic and non-seismic methods applied in the O&G industry. Moreover many techniques discussed in the book here proposed are unedited or only partially discussed in few specific articles.;

Numerical earth models




Jean-Laurent Mallet

In this book the main problems related to the construction of an Earth-Model are presented and discussed. The first three chapters are dedicated to the classical methods that can be used to build numerical models, in particular, the author proposes: - some of the classical modeling techniques used in Computer Aided Design (CAD) to model surfaces and their inadequacy for modeling complex geological objects, in particular: - classical interpolation techniques used to model surfaces; - topological models used to describe the connections between surfaces and volumes; - an overview of geomodeling methods dedicated to the discrete modeling of geological objects, in particular: - the Discrete-Smooth-Interpolation method (DSI); - meshing techniques to model surfaces and grids; - a presentation of the classical ?Shared-Earth-Model? (SEM) paradigm consisting in a Structural-Model (SM) plus a Property-Model (PM): SEM = SM + PM - a discussion concerning the problems raised by the (in) compatibility between the Structural-Model (SM) and the Property-Model (PM).

Principles of seismic velocities and time-to-depth conversio




Mac Al-Chalabi

Despite its fundamental importance for acquiring an accurate picture of the subsurface, the topic of time-to-depth conversion on the basis of true propagation velocities has never been addressed in the form of a comprehensive, dedicated book. The present book has long been overdue for bridging this obvious gap in geoscience. Geophysicists proficient in data processing fully appreciate that depth imaging, despite the excellence achieved in data quality and lateral positioning, does not amount to true or accurate depth conversion. This is because modelling "velocities" in processing (described in the book as "pro-velocities") can often be quite different from the actual propagation velocities. The many forms of velocities, their interrelationships, their derivation, their assessment and the various factors that could affect their stability and accuracy, are all thoroughly covered. Common misconceptions are brought to notice. The main thrust is for the use of these velocities for time-todepth conversion. Extensive details of depth conversion procedures are established, together with velocity models, each to suit the various depth conversion situations arising in practice. Factors affecting depth conversion results and estimation of the associated uncertainty are extensively covered. Clarity and simplicity of presentation and practical applicability are a prime consideration. Demystifying some topics that are vague to a majority of geoscientists (e.g. anisotropy) also receives ample attention. The book is written for the interpretation geophysicist working in exploration and development, for the seismic processor seeking a wider perspective on the quality of output and on the provision of the data to help the "frontline" geoscientist, for the geologist using geophysical methods as a tool at various levels of detail in the evaluation of the subsurface, and for the geoscientist at large.

Seismic geomechanics




Jorg Herwanger

Three-dimensional geomechanical models have seen a rapid increase in use by the oil and gas industry, with applications from drilling to reservoir management. Yet few university programmes include applied geomechanics as part of their curriculum. This course aims to fill this gap and presents currently available methods to build, calibrate and interpret 3D and 4D geomechanical models. The course participant will become comfortable with stress and strain tensors, understand the basics of deriving elastic and strength properties, learn how to use seismic data to build geomechanical models and understand the importance of calibrating geomechanical models with observations.

Seismic imaging




Etienne Robein

The book presents the various seismic imaging methods currently in use in the Oil and Gas industry in a unified and almost equation-free approach. Guided step by step through each method well illustrated by figures and examples, the reader will discover differences between time and depth imaging, how they impact the quality of the seismic image, the distinction between Kirchhoff, Gaussian Beam and other Beam techniques, principles of ray-based tomography and how it may be used after wave-equation methods, in what sense two-way Reverse Time Migration differs from one-way Shot Point migration, what are the emerging routes for migration velocity analysis, what can we expect from Full Waveform Inversion and at what cost, how 3D and wide azimuth acquisition impact imaging, and answers to many other questions.

Seismic multiple removal techniques




Eric Verschuur

Multiple reflections have been a major problem since the beginning of seismic exploration. In the last five decades a range of methods have been developed to suppress these refl ections and enhance the primaries. This book provides an overview of these techniques, starting with the deconvolution-based methods from the 1960s, via the move-out discrimination techniques of the 1980s and ending up with wave-equation based methods from the 1990s and their 3D extensions as developed in the 2000s. Furthermore, the current challenges in multiple removal and their relation with seismic imaging and inversion are treated. Besides this overview, the book also discusses processing concepts that are required to better understand various technologies, such as high-resolution seismic data transforms (Fourier, Radon), adaptive fi ltering techniques, wave-equation based forward and inverse wave propagation and the processing of seismic data in different transform domains. The emphasis is not to thoroughly treat the mathematics but to present some understanding of the physical concepts behind each method, illustrated with clear examples.

Seismic reservoir characterization




Philippe Doyen

In this publication, Philippe Doyen reviews some of the most widely used workflows for constraining 3-D earth models with seismic data. They typically involve a sequential process where seismic data are first inverted to elastic properties. Inverted data are then depth-converted and transferred into the earth model framework, where the seismic attributes are used to guide the interpolation of reservoir properties between the wells. Geostatistics provides a number of tools for this purpose, including generalized regression techniques such as cokriging and kriging with external drift, stochastic simulation with seismic constraints and geostatistical inversion. These techniques are reasonably well-established and their application can lead to significantly better constrained earth models. So what are the remaining challenges for seismic data integration in earth models? In particular, what are the main limitations or bottlenecks with current approaches that need to be addressed in order to make this integration more widely applicable? In the last few paragraphs, Philippe Doyen lists some of the future challenges and new directions in seismic earth modelling.

Seismic surveillance for reservoir delivery from a practitio




Olav Barkved

Time-lapse seismic surveys or 4D seismic offers snapshots of a producing hydrocarbon reservoir and its surroundings and is the most common seismic surveillance technique in the oil and gas industry. New developments of this technology includes permanent seismic installations; observations of changes outside the reservoirs and a link to geomechanics and the use of passive recordings. In this book we are using examples from the Valhall field to illustrate examples of seismic surveillance that will include data examples from marine towed 4D, frequent surveying using permanently installed sensors, in-well recordings and analysis of passive data, including micro seismicity. Some of the historical 4D examples, an update on the state of use of permanent recordings systems are also discussed.

The principles of quantitative acoustical imaging




Eric Verschuur

This book presents a systematic approach to imaging of acoustic reflection measurements and the extraction of media property information from the image amplitudes, based on wave theory. Although the approach is valid for a wide range of acoustical frequencies and applications, there is a bias towards seismic imaging, because imaging the earth is one of the most challenging of all acoustical imaging applications. In addition, in oil and gas exploration and production applications the need to obtain quantitative information on the media properties of the object to be imaged is most strongly felt. However, the methods presented are equally valid for ultra-sonic non-destructive testing, or medical diagnostic applications. The theory of acoustic wave propagation is presented, from the constituent equations Hooke and Newton, to the acoustic wave equation, to wavefield extrapolation and to extraction of image amplitudes. A feature of this book is the careful analysis of every step in these processes in terms of the linearity of the wavefields in the media property representation they are inverted for. Alternatively, the extrapolated wavefields can be inverted directly for the media properties. Towards the end of the book it is demonstrated that significantly higher resolution quantitative information can be obtained if the non-linearity is taken into account.

Velocities, time-imaging and depth-imaging; principles and m




Etienne Robein

There are numerous textbooks and publications on seismic processing, and in particular migration. However, we do not know of any work giving an overview of the many types of 'velocities' used in Seismics and how they relate to the different methods involved in the creation of the seismic image. This text reviews the imaging methods used in the oil and gas industry today, with a unique emphasis on this relationship between imaging and velocity. It addresses imaging in both time and depth domains, spanning the range of complexity from NMO correction to sophisticated pre-stack migrations. Recent tools, such as inversion and demigration, and new directions, e.g. accounting for anisotropy have also been tackled. The work is comprehensively illustrated with a total of more than 200 figures. The book should therefore be of interest to students looking for a complete introduction to seismic imaging techniques and their respective theoretical and practical merits and limitations. It is equally written to serve as a reference book for industry professionals, both generalists and specialists, who wish to revise standard techniques or take a look at some of the newer developments. In particular, interpreters, who participate in more and more tasks involving seismic velocities, will find answers to many of the questions which arise when, for example, tying seismic images to wells, creating post- and pre-stack time migration velocity fields, building a velocity model for depth migration or simply converting maps from time to depth.
