Book Synopsis Seismic Forward Modeling of Fractures and Fractured Medium Inversion by : Xiaoqin Cui
Download or read book Seismic Forward Modeling of Fractures and Fractured Medium Inversion written by Xiaoqin Cui and published by Springer. This book was released on 2017-06-09 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: This detailed book systematically investigates subsurface geological fractures using rock mechanics, geology, and geophysics. Based on geological fracture mechanisms and fracture boundary conditions, it presents new finite-difference equations for the simulation of seismic wave responses to geological fractures, and proposes innovative AVO inversion equations for the accurate estimation of the rock properties of the fractured medium. It employs schematics, snapshots, color images and charts to demonstrate the mechanical characteristics of the fractures, the seismic wave-field response to the fractures, the seismic data attributes of the fractures and the rock properties of the fractures obtained via inversion. It provides a new methodology for enhancing geological fracture detection technology and for the accurate delineation of fractured reservoirs that ultimately benefits reservoir and mining engineers, geologists and geophysicists in terms of optimizing reservoir recovery, well performance and mining safety.

Book Synopsis Reflection Coefficients and Azimuthal AVO Analysis in Anisotropic Media by : Mark Naumovich Berdichevskiĭ
Download or read book Reflection Coefficients and Azimuthal AVO Analysis in Anisotropic Media written by Mark Naumovich Berdichevskiĭ and published by SEG Books. This book was released on 2002 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: Observing offset-dependent seismic reflectivity has proven to be a valuable exploration tool for the direct detection of hydrocarbons. This monograph provides a comprehensive review of reflection coefficients and their approximations in isotropic media, followed by an in-depth discussion of reflection amplitudes in anisotropic media. No prior knowledge of seismic anisotropy is assumed, and considerable effort is spent to introduce wave propagation and medium parameterizations useful for surface seismic applications in the presence of anisotropy. The first anisotropic model discussed is transverse isotropy with a vertical axis of symmetry (VTI media), typically used to describe shale sequences. Then the study of VTI reflection coefficients is extended to transverse isotropy with a horizontal axis of symmetry (HTI) - the symmetry system that describes a system of parallel vertical cracks. Analysis of the "Shuey-type" approximate HTI P-wave reflection coefficient makes it possible to devise fracture-detection algorithms based on the inversion of azimuthal differences of the P-wave AVO gradient. The monograph also presents analysis of shear- and converted-wave reflection coefficients for HTI and orthorhombic models, discusses practical aspects of applying the azimuthal AVO analysis, and mentions promising recent results.

Book excerpt: As our speculative understanding of the physics behind seismic waves has developed, physical and numerical modeling have prominently innovative and now augment applied seismology for better prediction and engineering practices. The interest in seismic inversion techniques has been growing steadily over the last couple of years. Integrated studies are essential to hydrocarbon development projects and inversion is one of the means to extract additional information from seismic data. This has led to some novel applications such as using artificially-induced shocks for exploration of the Earth's subsurface and seismic stimulation for increasing the productivity of oil wells. Obviously, drilling a well and running a set of logging tools gives us much more information. However, the advantage of the seismic method is that coverage can be made over large areas of the earth's surface. This is especially true of the large three-dimensional surveys that are now routinely being acquired. For this reason, seismic inversion is an important processing tool. This book demonstrates the latest techniques and advances in seismic inversion from theoretical approach, data acquisition and interpretation, to analyses and numerical simulations, as well as research applications. The main objective of this work is the development and implementation of a stochastic model algorithm for seismic inversion to improve reservoir characterization. Underground fractures play an important role in the storage and movement of hydrocarbon fluid. Fracture rock physics has been the useful bridge between fracture parameters and seismic response. In this book, we aim to use seismic data to predict subsurface fractures based on rock physics and also proposed the method which uses seismic data to invert the elastic and rock physics parameters of fractured rock. The base idea of this work is precisely to incorporate stochastic simulation and co-simulation methodologies to conceive and implement a model of global seismic inversion and creating uncertainty linked to areas with different seismic quality.
Book Synopsis Seismic Fracture Characterization by : Enru Liu
Download or read book Seismic Fracture Characterization written by Enru Liu and published by . This book was released on 2012 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last three decades, seismic anisotropy has evolved from a purely academic research topic into applications in the mainstream of applied geophysics. Today, nobody doubts that the earth is anisotropic and most (if not all) hydrocarbon reservoirs are anisotropic. Since shale accounts for 70% of sedimentary basins and fractures exist in all reservoirs, seismic anisotropy may be even more extensive than we think. Taking anisotropy into account in seismic processing has improved the quality of seismic images, even though it makes seismic processing more challenging since additional parameters are needed. At the same time, fracture characterization using the concept of seismic anisotropy has added value in reservoir characterization, reservoir management, and has increased recovery and optimized well locations. This book and the associated course provide an introduction to the fundamental concepts of seismic fracture characterization by introducing seismic anisotropy, equivalent-medium representation theories of fractured rock and methodologies for extracting fracture parameters from seismic data. We focus on practical applications using extensive field data examples. Includes cast studies demonstrating the applicability, workflow and limitations of this technologyContains physical laboratory 3D experiments where fracture distributions are known, a Middle East fractured carbonate reservoir and a fractured tight gas reservoir. Builds discrete fracture network models incorporating all data. These models should not only be geologically consistent but also geophysically and geomechanically consistent, so that the models can be used to forecast the behaviour and performance of fractured reservoirs.

How can changes in fracture systems be predicted and controlled? Among other topics, the committee provides a geomechanical understanding of fracture formation, reviews methods for detecting subsurface fractures, and looks at the use of hydraulic and tracer tests to investigate fluid flow. The volume examines the state of conceptual and mathematical modeling, and it provides a useful framework for understanding the complexity of fracture changes that occur during fluid pumping and other engineering practices. With a practical and multidisciplinary outlook, this volume will be welcomed by geologists, petroleum geologists, geoengineers, geophysicists, hydrologists, researchers, educators and students in these fields, and public officials involved in geological projects.
Book Synopsis Understanding the Micro to Macro Behaviour of Rock-fluid Systems by : Richard Paul Shaw
Download or read book Understanding the Micro to Macro Behaviour of Rock-fluid Systems written by Richard Paul Shaw and published by Geological Society of London. This book was released on 2005 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding how fluids flow through though rocks is very important in a number of fields. Almost all of the world's oil and gas are produced from underground reservoirs. Knowledge of how they got where they are, what keeps them there and how they migrate through the rock is very important in the search for new resources, as well as for maximising the extraction of as much of the contained oil/gas as possible. Some contributors to this volume have been trying to understand real rocks in real situations and others have been working on computer models and laboratory simulations. Put together, these approaches have yielded very useful results, many of which are discussed in this volume.
Book Synopsis Static Conceptual Fracture Modeling by : Ronald A. Nelson
Download or read book Static Conceptual Fracture Modeling written by Ronald A. Nelson and published by John Wiley & Sons. This book was released on 2019-10-07 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modelling of flow in naturally fractured reservoirs is quickly becoming mandatory in all phases of oil and gas exploration and production. Creation of a Static Conceptual Fracture Model (SCFM) is needed as input to create flow simulations for today and for prediction of flow into the future. Unfortunately, the computer modelers tasked with constructing the gridded fracture model are often not well versed in natural fracture characterization and are often forced to make quick decisions as to the input required by the software used to create these models. Static Conceptual Fracture Modelling: Preparing for Simulation and Development describes all the fracture and reservoir parameters needed to create the fracture database for effective modelling and how to generate the data and parameter distributions. The material covered in this volume highlights not only natural fracture system quantification and formatting, but also describes best practices for managing technical teams charged with creating the SCFM. This book will become a must on the shelf for all reservoir modelers.
