This book dwells on the fundamentals of seabed seismic in terms of data acquisition, QC and pre-processing. The focus is on receivers placed on the seabed— hydrophones to measure pressure in water (p-waves), geophones or accelerometers to measure vertical particle motion (p-waves) and horizontal particle motion (s-waves). The discussion is mainly on four components (4C) which more or less covers other multi-component seismic techniques. The first three chapters end with a set of exercises that will be of tremendous help within the educational environment. Chapter 1 defines seabed seismic and presents its advantages over conventional marine seismic methods. Experiences or implementation of the technique in some oil fields are given. In chapter 2, some basic signal properties are given, including the PS converted wave process and the derivation of the common conversion point (CCP) approximation formula. Basic data acquisition techniques are treated, including topics like sensor orientation, CCP binning and shear wave splitting. P-wave to S-wave velocity ratio (Gamma) is explained. The basics of QC and processing of seabed seismic data are treated in Chapter 3 where two model processing work-flows are showcased to explain the requisite data processing keys. The improvements in seabed seismic have not been without difficulties. Some of these challenges are treated in Chapter 4.

Download Seismic Exploration Methods Book in PDF, ePub and Kindle
This book describes the seismic methods used in geophys ical exploration for oil and gas in a comprehensive, non rigorous, mathematical manner. I have used it and its predecessors as a manual for short courses in seismic methods, and it has been extensively revised time and again to include the latest advances in our truly remark able science. I once called it, "Advanced Seismic Inter pretation," but the geophysicists who attended the courses always wondered when I was going to start dis cussing interpretation. They discovered at the end that I never did discuss interpretation as they knew it. No men tion was made of reflection picking, posting times, map ping, contouring, and things they already knew perfectly well. Instead, I discussed Fourier transforms, sampling theory, impulse responses, distortion operators, Wiener filters, noise in f-k space, velocity spectra, wave-equation migration, and direct detection of hydrocarbons as each of these topics appeared on the seismic scene. I wanted the geophysicists to think beyond the routine ofinterpre tation, to develop a better understanding of why seismic sections look as they do, to have a better feel for what digital processing is doing, for good or evil, to the seismic data. I attempted to stretch their minds. Whitehead said it best: "A mind once stretched by a new idea can never shrink to its former dimension. " May this book be a suc cessful mind-stretcher. R. L.

This book has been written for those who need a solid understanding of the seismic exploration method without difficult mathematics. It is presented in a format that allows one to naturally progress from the underlying physical principles to the actual seismic method. The mathematics needed for the subject is kept as simple as possible; students only need high school physics and mathematics to thoroughly grasp the principles covered. Dr. Stark has developed this text and honed its content with feedback from hundreds of students over nearly two decades of teaching seismic exploration geophysics. This textbook will teach students the principles for the detection of geologic structures, earthquake zones and hazards, resource exploration, and geotechnical engineering.This title is Winner of 2009 Text and Academic Authors Association "Textbook Excellence Award"

Download Marine Geophysics Book in PDF, ePub and Kindle
Provides a comprehensive review of techniques used to explore the oceans and examines what geophysical observations reveal about the structure and tectonics of the seabed and the Earth's interior. Exploration of the oceans using geophysical methods has had a profound effect on the way we view the structure of the earth and its behaviour through geological time. Geophysics has also played a vital role in the search for petroleum and other natural resources lying beneath the seabed. This volume looks at: * the means of locating observations accurately and determining in detail the morphology of the sea floor * the powerful seismic techniques for imaging the Earth's interior from shallow coastal areas to deep-sea trenches * the gravity and magnetic fields over the oceans, heat flow, electrical and radiometric methods and measurements in offshore boreholes * geophysical observations on the development of the modern oceans, the structure of their deep basins, and the nature of their aseismic and seismically active margins. This book will be of interest to marine scientists and advanced undergraduates and postgraduates following courses on, or undertaking research in, geophysics, marine geology, oceanography, physical sciences, remote sensing, marine surveying and offshore engineering.

Download Ocean Seismo-Acoustics Book in PDF, ePub and Kindle
Seafloor investigation has long been a feature of not only seismology but also of acoustics. Indeed it was acoustics that produced depth sounders, giving us the first capability of producing both global and local maps of the seafloor. Subsequently, better instrumentation and techniques led to a clearer, more quantitative picture of the seabed itself, which stimulated new hypotheses such as seafloor spreading through the availability of more reliable data on sediment thickness over ocean basins and other bottom features. Geologists and geophysicists have used both acoustic and seismic methods to study the seabed by considering the propagation of signals arising from both natural seismic events and man-made impulsive sources. Although significant advances have been made in instrumentation, such as long towed geophysical arrays, ai r guns and ocean bot tom seismometers, the pic ture of the seafloor is still far from complete. Underwater acoustics concerns itself today with the phenomena of propagation and noise at frequencies and ranges that require an understanding of acoustic interaction at both of its boundaries, the sea surface and seafloor, over depths ranging from tens to thousands of meters. Much of the earlier higher frequency (>1 kHz) work included the characterization of the seafloor in regimes of reflection coefficients which were empirically derived from surveys. The results of these studies met with only limited success, confined as they were to those areas where survey data existed and lacking a physical understanding of the processes of reflection and scattering.

This two-volume handbook presents advanced research and operational information about hard minerals and hydrocarbons. It provides information in an integrated, interdisciplinary manner, stressing case histories. It includes review chapters, illustrations, graphs, tables, and color satellite images that present the results of gravity, geodetic, and seismic surveys and of 3-D sea floor sub-bottom visualizations. The data was obtained using satellites, aircraft, and ships from the Atlantic and Pacific Oceans, the Gulf of Mexico, and the Caribbean Sea. Major topics addressed in these volumes include geophysical methods used to explore for hydrocarbons, advanced radiometric and electrical methods for hard mineral searches, the role of geotechnology and seismic acoustics in overcoming geological hazards in selecting drilling sites and pipeline routes, and remote sensing techniques used to determine the physical properties of sediments.
