Download or read book 3C Seismic and VSP: Converted waves and vector wavefield applications written by James Gaiser and published by SEG Books. This book was released on 2016-06-30 with total page 637 pages. Available in PDF, EPUB and Kindle. Book excerpt: 3C seismic applications provide enhanced rock property characterization of the reservoir that can complement P-wave methods. Continued interest in converted P- to S-waves (PS-waves) and vertical seismic profiles (VSPs) has resulted in the steady development of advanced vector wavefield techniques. PS-wave images along with VSP data can be used to help P-wave interpretation of structure in gas obscured zones, of elastic and fluid properties for lithology discrimination from S-wave impedance and density inversion in unconventional reservoirs, and of fracture characterization and stress monitoring from S-wave birefringence (splitting) analysis. The book, which accompanies the 2016 SEG Distinguished Instructor Short Course, presents an overview of 3C seismic theory and practical application: from fundamentals of PS-waves and VSPs, through to acquisition and processing including interpretation techniques. The emphasis is on unique aspects of vector wavefields, anisotropy, and the important relationships that unify S-waves and P-waves. Various applications and case studies demonstrate image benefits from PS-waves, elastic properties and fluid discrimination from joint inversion of amplitude variations with offset/angle (AVO/A), and VSP methods for anisotropic velocity model building and improved reservoir imaging. The book will be of interest to geophysicists, geologists, and engineers, especially those involved with or considering the use of AVO/A inversion, fracture/stress characterization analyses, or interpretation in gas-obscured reservoirs.

Book Synopsis Land Seismic Case Studies for Near-Surface Modeling and Subsurface Imaging by : Öz Yilmaz
Download or read book Land Seismic Case Studies for Near-Surface Modeling and Subsurface Imaging written by Öz Yilmaz and published by SEG Books. This book was released on 2021-06-30 with total page 1056 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written for practicing geophysicists, “Land Seismic Case Studies for Near-Surface Modeling and Subsurface Imaging” is a comprehensive guide to understanding and interpreting seismic data. The culmination of land seismic data acquisition and processing projects conducted by the author over the last two decades, this book contains more than nearly 800 figures from worldwide case studies—conducted in both 2D and 3D. Beginning with Chapter 1 on seismic characterization of the near-surface, Chapter 2 presents near-surface modeling by traveltime and full-wave inversion, Chapter 3 presents near-surface modeling by imaging, and then Chapter 4 includes detailed case studies for near-surface modeling. Chapter 5 reviews single- and multichannel signal processing of land seismic data with the key objective of removing surface waves and guided waves that are characterized as coherent linear noise. Uncommon seismic data acquisition methods, including large-offset acquisition in thrust belts to capture the large-amplitude supercritical reflections, swath-line acquisition, and joint PP and SH- SH seismic imaging are highlighted in Chapter 6, and Chapter 7 presents image-based rms velocity estimation and discusses the problem of velocity uncertainty. The final two chapters focus exclusively on case studies: 2D in Chapter 8 and 3D in Chapter 9. An outstanding teaching tool, this book includes analysis workflows containing processing steps designed to solve specific problems. Essential for anyone involved in acquisition, processing, and inversion of seismic data, this volume will become the definitive reference for understanding how the variables in seismic acquisition are directly reflected in the data.

Book Synopsis S-wave Velocity Estimation Using Converted-wave VSP Data by : Minyu Zhang
Download or read book S-wave Velocity Estimation Using Converted-wave VSP Data written by Minyu Zhang and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the key benefits of zero-offset vertical seismic profile (VSP) is to provide accurate velocity information in the vicinity of boreholes. For 3-component VSP, we usually pick the first break times of direct downgoing S-wave to estimate the S-wave velocity. However, the direct downgoing S-wave arrivals may be too weak to pick precisely. To mitigate this disadvantage, I present a new S-wave velocity estimation method using converted (P-to-S) waves in VSP data. Traveltimes of the strongest converted PS-wave are used to build an S-wave velocity model. Two synthetic traveltime datasets are generated and used to test the method. The first one, without noise, is used to investigate the sensitivities of results to different initial models. The inversion results are slightly different: the RMS error between the true velocity and the inverted velocity varies from 1 m/s to 10 m/s for different initial models. The second test, with random noise, explores the sensitivities of results to errors in picked traveltimes. Results show that the RMS error of output velocity varies from 2 m/s to 92 m/s when the RMS error of input traveltimes ranges from 0.1 ms to 8 ms. In addition to the synthetic tests, real 3-component zero-offset VSP and offset VSP datasets from the Huabei oil field, China are examined using the proposed method. The VSP survey used a dynamite source and 3-component receivers, with the receiver depth from 360 m to 2020 m. The inversion results show that, from 360 m to 900 m depths, the S-wave velocity derived from offset VSP fits quite well with that obtained from zero-offset VSP. The Vp/Vs is approximated 2.8 and the lithology is mudstone with sandstone. From 910 m to 2020 m, the S-wave velocity derived from offset VSP is close to that from zero-offset VSP. The Vp/Vs is around 1.7 and the lithology is primarily limestone and dolomite.

Book Synopsis Well Seismic Surveying and Acoustic Logging by : Jean-Luc Mari
Download or read book Well Seismic Surveying and Acoustic Logging written by Jean-Luc Mari and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approaches that are typically applied in deep exploration geophysics, combining different seismic and logging methods, can be technically adapted for certain geotechnical or hydrogeological surveys or some site characterizations in the framework of seismic hazard studies. Currently it is entirely feasible to implement this type of geophysical surveying if the situation requires. After reviewing the current state of knowledge regarding borehole measurements of subsurface shear velocities applied to the geotechnical field, this book illustrates the feasibility of carrying out vertical seismic profiles (VSPs) and logs in this field. This approach also illustrates the value of combining velocity measurements of formations provided by borehole seismic tools (VSP) and acoustic (sonic) tools. An innovative example of the application of borehole seismic and logging methods is then presented in the case study of a relatively near-surface (from 20 to 130 m) karst carbonate aquifer. It shows how a multi-scale description of the reservoir can be carried out by integrating the information provided by different 3D-THR surface seismic methods, full waveform acoustic logging, VSP with hydrophones, borehole optical televiewer and flow measurements. In this book the authors provide readers with guidelines to carry out these operations, in terms of acquisitions as well as processing and interpretation. Thus, users will be able to draw inspiration to continue transferring petroleum techniques and other innovative methods for use in near-surface studies.

Book Synopsis Mob Control: Models of Threshold Collective Behavior by : Vladimir V. Breer
Download or read book Mob Control: Models of Threshold Collective Behavior written by Vladimir V. Breer and published by Springer. This book was released on 2017-01-24 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents mathematical models of mob control with threshold (conformity) collective decision-making of the agents. Based on the results of analysis of the interconnection between the micro- and macromodels of active network structures, it considers the static (deterministic, stochastic and game-theoretic) and dynamic (discrete- and continuous-time) models of mob control, and highlights models of informational confrontation. Many of the results are applicable not only to mob control problems, but also to control problems arising in social groups, online social networks, etc. Aimed at researchers and practitioners, it is also a valuable resource for undergraduate and postgraduate students as well as doctoral candidates specializing in the field of collective behavior modeling.
