Understanding Seismic Anisotropy in Exploration and Exploitation (second edition)Understanding Seismic Anisotropy in Exploration and Exploitation, second edition

Leon Thomsen
Understanding Seismic Anisotropy in Exploration and Exploitation (second edition) by Leon Thomsen is designed to show you how to recognize the effects of anisotropy in your data and to provide you with the intuitive concepts that you will need to analyze it. Since its original publication in 2002, seismic anisotropy has become a mainstream topic in exploration geophysics.  With the emergence of the shale resource play, the issues of seismic anisotropy have become central, because all shales are seismically anisotropic, whether fractured or not. With the advent of wide-azimuth surveying, it has become apparent that most rocks are azimuthally anisotropic, with P-wave velocities and P-AVO gradients varying with source-receiver azimuth. What this means is that analysis of such data with narrow-azimuth algorithms and concepts will necessarily fail to get the most out of this expensively acquired data. The issues include not only seismic wave propagation, but also seismic rock physics. Isotropic concepts including velocity, Young's modulus, and Poisson's ratio have no place in the discussion of anisotropic rocks, unless qualified in some directional way (e.g., vertical Young's modulus). Likewise, fluid substitution in anisotropic rocks, using the isotropic Biot/Gassmann formula, leads to formal errors, because the bulk modulus does not appear, in a natural way, within the anisotropic P-wave velocity. This updated edition is now current as of 2014.

AVOAVO

Satinder Chopra and John P. Castagna
AVO (SEG Investigations in Geophysics No. 16) by Satinder Chopra and John Castagna begins with a brief discussion on the basics of seismic-wave propagation as it relates to AVO, followed by a discussion of the rock-physics foundation for AVO analysis including the use of Gassmann's equations and fluid substitution. Then, the early seismic observations and how they led to the birth of AVO analysis are presented. The various approximations for the Zoeppritz equations are examined, and the assumptions and limitations of each approximation are clearly identified. A section on the factors that affect seismic amplitudes and a discussion of the processing considerations important for AVO analysis are included. A subsequent section explores the various techniques used in AVO interpretation. Finally, topics including the influence of anisotropy in AVO analysis, the use of AVO inversion, estimation of uncertainty in AVO analysis, converted-wave AVO, and the future of the AVO method are discussed. Equally helpful to new entrants into the field as well as to seasoned workers, AVO will provide readers with the most up-to-date knowledge on amplitude variation with offset.

Remote Sensing in Action: The Curious Case of Sherlock Holmes and Albert Einstein52 Things You Should Know About Geology

Edited by Matt Hall
Every subsurface professional will enjoy these fifty-two short essays by more than forty petroleum geoscientists. The list of authors includes some of the most successful explorationists of our time, as well as some scientists right at the start of their careers. The range of topics could scarcely be broader, covering fieldwork and mapping, beaches and turbidites, and ways to handle the inevitable uncertainty in all geological models.

52 Things You Should Know About Geophysics52 Things You Should Know About Geophysics

Edited by Matt Hall and Evan Bianco
There is something for every subsurface professional in these fifty-two short essays by more than three dozen petroleum geoscientists. The roster includes some of the most prolific geophysicists of our time, as well as some recently qualified scientists. The topics are even more diverse, ranging from anisotropic media to pre-stack interpretation, and from stories of early seismic workstations to career advice for the future.

Remote Sensing in Action: The Curious Case of Sherlock Holmes and Albert EinsteinRemote Sensing in Action: The Curious Case of Sherlock Holmes and Albert Einstein

Enders A. Robinson and Dean Clark
Remote Sensing in Action: The Curious Case of Sherlock Holmes and Albert Einstein (SEG Geophysical Monograph Series No. 18) by Enders A. Robinson and Dean Clark questions a basic assumption of the scientific method — that new theories or experimental results are communicated effectively by traditional methods (e.g., presentations at professional meetings or publication in a peer-reviewed journal) — and suggests that the scientific method needs to be applied to the scientific method itself to find out if other styles of communication might work better. In a highly entertaining format, the book uses the enormously popular fictional characters created by Sir Arthur Conan Doyle to unravel and explain the historical underpinnings of remote sensing. The extended appendices guarantee that all of the science of remote sensing is included in this book of "scientific fiction." The story covers more than 2000 years, beginning with Pythagoras in ancient Greece and ending with Einstein's first article on relativity in 1905. Light-years beyond a traditional science textbook, this detective story set in 1905 will teach students of all ages about the exciting journey of scientific discovery.

Microseismic Imaging of Hydraulic Fracturing: Improved Engineering of Unconventional Shale ReservoirsMicroseismic Imaging of Hydraulic Fracturing: Improved Engineering of Unconventional Shale Reservoirs

Shawn Maxwell
Microseismic Imaging of Hydraulic Fracturing: Improved Engineering of Unconventional Shale Reservoirs (SEG Distinguished Instructor Series No. 17) covers the use of microseismic data to enhance engineering design of hydraulic fracturing and well completion. The book, which accompanies the 2014 SEG Distinguished Instructor Short Course, describes the design, acquisition, processing, and interpretation of an effective microseismic project. The text includes a tutorial of the basics of hydraulic fracturing, including the geologic and geomechanical factors that control fracture growth. In addition to practical issues associated with collecting and interpreting microseismic data, potential pitfalls and quality-control steps are discussed. Actual case studies are used to demonstrate engineering benefits and improved production through the use of microseismic monitoring. Providing a practical user guide for survey design, quality control, interpretation, and application of microseismic hydraulic fracture monitoring, this book will be of interest to geoscientists and engineers involved in development of unconventional reservoirs.

Hydrocarbon Seepage: From Source to SurfaceHydrocarbon Seepage: From Source to Surface

Edited by Fred Aminzadeh, Timothy B. Berge, and David L. Connolly
With the increased resolution power of many geophysical methods, we are seeing direct evidence of seeps on a wide variety of data, including conventional seismic. New methods and technology have also evolved to better measure and detect seeps and their artifacts and reservoir charge and to map migration and remigration routes. In addition, detection of seepage is important for minimizing the risks associated with shallow gas drilling hazards, ensuring platform stability, and preventing well blow-outs. This volume (SEG Geophysical Developments Series No. 16) is organized into three sections, each with a different focus. The first section, "Descriptions and Observations of Seeps," includes field studies, observations of seep environments, migration systems, and use of modern sampling techniques. The second section, "Science of Seepage — Methodology," discusses new techniques including DNA sampling, use of biomarkers, neural network analysis, and remote multispectral analysis. The final section, "Implications of Seeps," shows how seeps may be used to reduce prospect risk and assess risk elements such as trap seal and fault leakage. This volume, copublished by SEG and AAPG, is intended to be a landmark reference for understanding seep occurrences and demonstrating the development and use of new technologies to image them with a focus on exploration and field development applications. It will be a valuable reference to geologists, geophysicists, and petroleum engineers everywhere.
