Download or read book Theory and Practice of High Resolution Seismic HRS Geo Technology Application written by Vladimir L. Trofimov and published by Springer Nature. This book was released on 2024-03-08 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book outlines the scientific, methodological and practical foundations for applying High Resolution Seismic HRS-Geo Technology in order to build detailed 2D and 3D seismic acoustic models in the form of acoustic impedances (AI) and reflection coefficients (RC) and the most important geological indicators. The monograph is a continuation of the book by the same authors "Oil and Gas Reservoir Prospecting and Exploration: High-Resolution Seismic HRS techniques and technology". Particular attention is paid to improving the process of searching for AI and RC models using the vector of objective functions, in which various types of residuals between real and model data are iteratively calculated. The well-known criteria for predicting the oil and gas potential of productive deposits from the standpoint of the system analysis principles and the set of geological indicators found from the HRS data are analyzed. The features of solving the main seismogeological problems using HRS-Geo Technology modules are shown, illustrated by numerous examples, and using a special (optimal) processing graph and a set of additional seismic record regularization procedures that provide maximum detail of high-resolution seismic data. The book is meant for scientists and specialists involved in in-depth complex geological interpretation of seismic data in the search and exploration of oil and gas deposits, as well as students of geophysical and geological specialties, graduate students of these specializations and developers.
Download or read book Shallow High resolution Reflection Seismics written by Jan Brouwer and published by Pergamon. This book was released on 1998 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book covers all aspects of acquisition, processing and interpretation of shallow reflection seismic data for geotechnical and environmental purposes. Chapter 1 provides a thorough exposition of (i) the mathematical foundations of digital seismics, (ii) the physics of wave propagation in solids, (iii) the mathematical tools for the analysis of wave fields. This theoretical part is based extensively on first principles, thus the book can be used as a stand-alone reference to all aspects of shallow reflection seismics. Chapter 2 describes the field instruments, including the physical principles underlying them and their modern implementation, and the acquisition techniques that allow to obtain the best data under the given technical and operational constraints. Chapters 3-5 describe the processing required to maintain the resolution of seismic data without sacrificing other attributes of the data. The discussion is particularly thorough in where the required techniques go beyond the standard processing steps known from exploration seismics. Chapters 6-10 describe the use of portable vibrators in geotechnical surveying, that was pioneered by the authors and their colleagues. The first four of these chapters, that describe the special techniques required and some of the opportunities offered by the use of these tools, are based on experience with the portable P-vibrator, while chapter 10 was added after the recent introduction of the portable S-vibrator to shallow surveying. All five chapters are accompanied by data from actual surveys. The book closes with six case histories from different settings in Western Europe based on impact sources weight drop and explosives.

Download or read book Application of Seismic Interferometry to Imaging a Crystalline Rock Environment at an Active VMS Mine in Flin Flon Manitoba Canada written by Eric Alexander Roots and published by . This book was released on 2016 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seismic interferometry is a technique by which the Green's function or impulse response between two receivers is recovered through the cross-correlation of the transmission responses recorded by those receivers. This technique has found several applications, including the generation of virtual shot gathers from ambient seismic noise for use in seismic reflection processing. In March of 2013, 336 receivers were deployed over the volcanogenic massive sulphide (VMS) deposit found at the Lalor mine in Manitoba, Canada. Approximately 300 hours of ambient seismic noise was recorded for the purpose of testing the effectiveness of seismic interferometry in imaging a crystalline rock environment. A time-domain beamforming algorithm was implemented to determine the locations of the sources present during recording. The results indicate that the vast majority of the recorded noise originated from mine and ventilation shafts located at the Lalor mine. Synthetic experiments were conducted to determine the effects such a source distribution would have on the application of seismic interferometry in the presence of dipping reflectors. The experiments show that if sources are located only on one side of a receiver line, the dip and lateral extents of reflectors will not be imaged properly. A technique involving beamforming and F-K filtering was developed to remove surface wave noise originating from near-field sources. Using this technique, the raw data was processed into virtual shot gathers free of surface wave noise. Virtual shot gathers were generated along 4 of the receiver lines and processed as separate 2-D reflection datasets. The resulting reflection profiles are compared against coincident DMO-stacked data from a larger 3-D active seismic survey conducted over the Lalor mine. Using this comparison in conjunction with knowledge of the local geology, events recovered in the passive reflection profiles are interpreted as either real reflections or spurious events, and possible explanations of their origin are given.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive overview of relative fidelity preservation processing methods and their applications within the oil and gas sector. Four key principles for wide-frequency relative fidelity preservation processing are illustrated throughout the text. Seismic broadband acquisition is the basis for relative fidelity preservation processing and the influence of seismic acquisition on data processing is also analyzed. The methods and principles of Kirchhoff integral migration, one-way wave equation migration and reverse time migration are also introduced and illustrated clearly. Current research of relative amplitude preservation migration algorithms is introduced, and the corresponding numerical results are also shown. RTM (reverse time migration) imaging methods based on GPU/CPU systems for complicated structures are represented. This includes GPU/CPU high performance calculations and its application to seismic exploration, two-way wave extrapolation operator and boundary conditions, imaging conditions and low frequency noise attenuation, and GPU/CPU system based RTM imaging algorithms. Migration velocity model building methods in depth domain for complicated structures are illustrated in this book. The research status and development of velocity model building are introduced. And the impacting factors are also discussed. Several different velocity model building methods are also represented and analyzed.

Available in PDF, EPUB and Kindle. Book excerpt: Seismic Reflection Processing coherently presents the physical concepts, mathematical details and methodology for optimizing results of reservoir modelling, under conditions of isotropy and anisotropy. The most common form of anisotropy - transverse isotropy - is dealt with in detail. Besides, practical aspects in reservoir engineering - such as interval isotropic or anisotropic properties of layered media; identifying lithology, pore-fluid types and saturation; and determining crack/fracture-orientations and density - form the core of discussions. This book incorporates significant new developments in isotropic and anisotropic reflection processing, while organizing them to improve the interpretation of seismic reflection data and optimizing the modeling of hydrocarbon reservoirs. It is written primarily as a reference and tutorial for graduate/postgraduate students and research workers in geophysics.

Available in PDF, EPUB and Kindle. Book excerpt: Seismic refection surveying is a well proven geophysical method for delineating in detail the deep structure of sedimentary basins. Recently, it has also been applied in igneous and metamorphic (crystalline) rock environments. For cost and access reasons most of the data collected in crystalline terrains has been acquired by 2D crooked line profiling. But where the survey geometry is significantly irregular and the geologic structures have cross-profile dip, standard 2D imaging procedures severely underperform. My research has focused on finding remedies for the above problems by exploring and developing processing methods which usefully exploit the 3D character of crooked line data, or by finding methods of imaging that are more tolerant to the errors. To these ends I have designed the following data manipulation processes: (1) '3D prestack migration of 2D crooked lane data'. Despite obvious data limitations, bands of reflectivity recorded in crooked line data are preserved and positioned to their true subsurface locations. (2) ' Optimum cross dip analysis'/'stack'. This algorithm first analyzes cross-profile dip of the imaged reflectors and then collapses recorded bands of reflectivity into single events. (3) 'Amplitude stack'. This is a simple procedure used as a measure of last resort when 1 and 2 fail to yield 3D structural information. From tests on synthetic data and two field data sets from the Archean Superior Province, I have found that: (1) When 2D crooked line geometry forms a 3D swath of data wider than a significant fraction of the Fresnel Zone radius at the depth of interest. 3D prestack migration will focus events in space well enough for interpretation. The process is, however, computationally cumbersome; (2) Although the cross dip stack does not output a 3D volume like prestack migration, and it retains only the stronger of overlapping reflective responses, it does provide most of the same interpretative information; (3) Amplitude stacks are surprisingly effective in imaging general structural trends. In general, it is often possible to recover the 3D geometry of the structure imaged by a 2D crooked line survey.
