Coding and Decoding Seismic Data: The Concept of Multishooting, Volume One, Second Edition, offers a thorough investigation of modern techniques for collecting, simulating, and processing multishooting data. Currently, the acquisition of seismic surveys is performed as a sequential operation in which shots are computed separately, one after the other. The cost of performing various shots simultaneously is almost identical to that of one shot; thus, the benefits of using the multishooting approach for computing seismic surveys are enormous. By using this approach, the longstanding problem of simulating a three-dimensional seismic survey can be reduced to a matter of weeks. Providing both theoretical and practical explanations of the multishooting approach, including case histories, this book is an essential resource for exploration geophysicists and practicing seismologists. Investigates how to collect, stimulate, and process multishooting data Addresses the improvements in seismic characterization and resolution that can be expected from multishooting data Provides information for the oil and gas exploration and production business that will influence day-to-day surveying techniques Covers robust decoding methods of undetermined mixtures, nonlinear decoding, the use of constraints in decoding processes, and nonlinear imaging of undecoded data Includes access to a companion site with answers to questions posed in the book

Researchers in the field of exploration geophysics have developed new methods for the acquisition, processing and interpretation of gravity and magnetic data, based on detailed investigations of bore wells around the globe. Fractal Models in Exploration Geophysics describes fractal-based models for characterizing these complex subsurface geological structures. The authors introduce the inverse problem using a fractal approach which they then develop with the implementation of a global optimization algorithm for seismic data: very fast simulated annealing (VFSA). This approach provides high-resolution inverse modeling results—particularly useful for reservoir characterization. Serves as a valuable resource for researchers studying the application of fractals in exploration, and for practitioners directly applying field data for geo-modeling Discusses the basic principles and practical applications of time-lapse seismic reservoir monitoring technology - application rapidly advancing topic Provides the fundamentals for those interested in reservoir geophysics and reservoir simulation study Demonstrates an example of reservoir simulation for enhanced oil recovery using CO2 injection

Students and professors of hydrology, ecology, land-use management, forest and range management, soil science, physical geography, soil and water conservation, and watershed management will welcome this revision of the 1969 edition of An Outline of Forest Hydrology by John D. Hewlett and Wade L. Nutter. The student pursuing a career in forest and wildland resources soon learns that no science is more fundamental to the art of land management than hydrology, but hydrology as a science traditionally has been subordinated to hydrology as technique. Older texts have focused on methods and applications to the exclusion of principle, occasionally leaving the hydrological effects of land use and vegetation to be interpreted from techniques rather than from knowledge of process. Soil, atmospheric, and vegetal phases of the hydrologic cycle of have neglected in many texts intended for the college student. Hewlett’s new book focuses on natural processes and is intended to guide further study and to serve as a base for class lectures. The subject matter is organized to introduce key ideas and principles and to provide consistent terminology and clear graphic material to aid the student in comprehending the complex literature of hydrology.

Information-Based Inversion and Processing with Applications examines different classical and modern aspects of geophysical data processing and inversion with emphasis on the processing of seismic records in applied seismology. Chapter 1 introduces basic concepts including: probability theory (expectation operator and ensemble statistics), elementary principles of parameter estimation, Fourier and z-transform essentials, and issues of orthogonality. In Chapter 2, the linear treatment of time series is provided. Particular attention is paid to Wold decomposition theorem and time series models (AR, MA, and ARMA) and their connection to seismic data analysis problems. Chapter 3 introduces concepts of Information theory and contains a synopsis of those topics that are used throughout the book. Examples are entropy, conditional entropy, Burg's maximum entropy spectral estimator, and mutual information. Chapter 4 provides a description of inverse problems first from a deterministic point of view, then from a probabilistic one. Chapter 5 deals with methods to improve the signal-to-noise ratio of seismic records. Concepts from previous chapters are put in practice for designing prediction error filters for noise attenuation and high-resolution Radon operators. Chapter 6 deals with the topic of deconvolution and the inversion of acoustic impedance. The first part discusses band-limited extrapolation assuming a known wavelet and considers the issue of wavelet estimation. The second part deals with sparse deconvolution using various 'entropy' type norms. Finally, Chapter 7 introduces recent topics of interest to the authors. The emphasis of this book is on applied seismology but researchers in the area of global seismology, and geophysical signal processing and inversion will find material that is relevant to the ubiquitous problem of estimating complex models from a limited number of noisy observations. Non-conventional approaches to data processing and inversion are presented Important problems in the area of seismic resolution enhancement are discussed Contains research material that could inspire graduate students and their supervisors to undertake new research directions in applied seismology and geophysical signal processing

The objective of seismic exploration is to delineate the subsurface structure of the earth. A large variety of computer-processing methods are available to transform the observed seismic data into a form that is more useful to the seismic interpreter. An important subdivision of these methods comes under the heading "Seismic Inversion and Deconvolution". Most seismic data are recorded either by geophone that measures particle velocity, or else by hydrophone that measures pressure. A dual sensor incorporates both a geophone and a hydrophone so simultaneous measurements of both particle velocity and pressure are obtained. Unprecedented improvements in inversion and deconvolution are made possible through the use of "Dual-Sensor Technology". The purpose of Seismic Inversion and Deconvolution, Part B: Dual-Sensor Technology is to provide the fundaments of dual-sensor technology. Previous work together with new results are brought together into a self contained whole. By using dual sensors in the acquisition of seismic data, new avenues are opened up that revolutionize all aspects of seismic inversion and deconvolution. Dual-sensor technology can lead to images of the subsurface of the earth that were previously thought unattainable. The implications for the oil industry are far reaching. Great new reserves of petroleum are waiting to be discovered through the use of dual sensor technology. Today, the main application of this work is with ocean bottom cable (OBC) methods. However, it is anticipated that dual sensor technology will soon be applied not only to all aspects of seismic oil exploration, but also to other disciplines involved with remote sensing.

Twilight in the Desert reveals a Saudi oil and production industry that could soon approach a serious, irreversible decline. In this exhaustively researched book, veteran oil industry analyst Matthew Simmons draws on his three–plus decades of insider experience and more than 200 independently produced reports about Saudi petroleum resources and production operations. He uncovers a story about Saudi Arabia’s troubled oil industry, not to mention its political and societal instability, which differs sharply from the globally accepted Saudi version. It’s a story that is provocative and disturbing, based on undeniable facts, but until now never told in its entirety. Twilight in the Desert answers all readers’ questions about Saudi oil and production industries with keen examination instead of unsubstantiated posturing, and takes its place as one of the most important books of this still–young century.
