Book Synopsis Application of 3-D Vsp in Reservoir Characterization by : Prajnajyoti Mazumdar

Download or read book Application of 3-D Vsp in Reservoir Characterization written by Prajnajyoti Mazumdar. This book was released on 2010-09. Available in PDF, EPUB and Kindle. Book excerpt: Development of unconventional reservoirs like tight- gas sandstones differs from conventional oil and gas reservoirs. Conventional surface seismic measurements generally do not give results that can drive the business in tight-sandstone fields because of its failure in reservoir-scale lithology and fracture identification. In this monograph we use an uncommon 3-D VSP survey done with horizontal vibrators and multi-level 3-C geophone tool to detect the lithology and fracture distribution in the subsurface.

Download or read book Demonstration of High-resolution Inverse VSP for Reservoir Characterization Applications written by . This book was released on 1991. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this project is the determination of inverse vertical seismic profiling (VSP) measurements using new experimental field instrumentation capable of providing at least an order of magnitude improvement in the resolution of structural details in comparison with conventional seismic images. This two-year project will entail instrumentation tests under controlled field conditions during the first year followed by full-scale field demonstration tests in a representative oil-bearing reservoir formation during the second year. An automatic time-picking program and a tomographic inversion program developed for processing interwell seismic data were generalized for processing reverse VSP data. A technical paper was submitted for publication to Geophysics. The paper is entitled; A Wax-Embedded Borehole Seismic Detector for High-Resolution Measurements.'' A copy of this manuscript is enclosed in the Appendix. 3 figs., 1 tab.

Book Synopsis Reservoir Characterization II by : Lake

Download or read book Reservoir Characterization II written by Lake. This book was released on 2012-12-02. Available in PDF, EPUB and Kindle. Book excerpt: Reservoir Characterization II contains the proceedings of the Second International Reservoir Characterization Conference held in Dallas, Texas in June 1989. Contributors focus on the characterization of reservoir processes and cover topics ranging from surface roughness in porous media and reservoir characterization at the mesoscopic scale to shale clast heterogeneities and their effect on fluid flow, permeability patterns in fluvial sandstones, and reservoir management using 3-D seismic data. This book is organized into six sections encompassing 43 chapters. The first 20 chapters deal with reservoir characterization at the microscopic, mesoscopic, and macroscopic scales. Topics include low-contrast resistivity sandstone formations; the use of centrifuge and computer tomography to quantify saturation distribution and capillary pressures; and cross-well seismology as a tool for reservoir geophysics. The chapters that follow deal with reservoir characterization at the megascopic scale; fractal heterogeneity of clastic reservoirs; heterogeneity and effective permeability of porous rocks; and drilling fluid design based on reservoir characterization. A chapter that outlines a procedure for estimating permeability anisotropy with a minipermeameter concludes the book. This book is a valuable resource for students and practitioners of petroleum engineering, geology and geological engineering, petroleum exploration, and geophysics.

Book Synopsis 3C Seismic and VSP: Converted waves and vector wavefield applications by : James Gaiser

Download or read book 3C Seismic and VSP: Converted waves and vector wavefield applications written by James Gaiser. This book was released on 2016-06-30. 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.
