Seismic Inversion

Seismic reservoir characterization aims to build 3-dimensional models of rock and fluid properties, including elastic and petrophysical variables, to describe and monitor the state of the subsurface for hydrocarbon exploration and production and for CO₂ sequestration. Rock physics modeling and seismic wave propagation theory provide a set of physical equations to predict the seismic response of subsurface rocks based on their elastic and petrophysical properties. However, the rock and fluid properties are generally unknown and surface geophysical measurements are often the only available data to constrain reservoir models far away from well control. Therefore, reservoir properties are generally estimated from geophysical data as a solution of an inverse problem, by combining rock physics and seismic models with inverse theory and geostatistical methods, in the context of the geological modeling of the subsurface. A probabilistic approach to the inverse problem provides the probability distribution of rock and fluid properties given the measured geophysical data and allows quantifying the uncertainty of the predicted results. The reservoir characterization problem includes both discrete properties, such as facies or rock types, and continuous properties, such as porosity, mineral volumes, fluid saturations, seismic velocities and density.  Seismic Reservoir Modeling:  Theory, Examples and Algorithms  presents the main concepts and methods of seismic reservoir characterization. The book presents an overview of rock physics models that link the petrophysical properties to the elastic properties in porous rocks and a review of the most common geostatistical methods to interpolate and simulate multiple realizations of subsurface properties conditioned on a limited number of direct and indirect measurements based on spatial correlation models. The core of the book focuses on Bayesian inverse methods for the prediction of elastic petrophysical properties from seismic data using analytical and numerical statistical methods. The authors present basic and advanced methodologies of the current state of the art in seismic reservoir characterization and illustrate them through expository examples as well as real data applications to hydrocarbon reservoirs and CO₂ sequestration studies.

This volume elucidates the design criteria and principles for steel structures under seismic loads according to Eurocode 8-1. Worked Examples illustrate the application of the design rules. Two case studies serve as best-practice samples.

The seismoelectric method consists of measuring electromagnetic signals associated with the propagation of seismic waves or seismic sources in porous media. This method is useful in an increasing number of applications, for example to characterize aquifers, contaminant plumes or the vadose zone. This book provides the first full overview of the fundamental concepts of this method. It begins with a historical perspective, provides a full explanation of the fundamental mechanisms, laboratory investigations, and the formulation of the forward and inverse problems. It provides a recent extension of the theory to two-phase flow conditions, and a new approach called seismoelectric beamforming. It concludes with a chapter presenting a perspective on the method. This book is a key reference for academic researchers in geophysics, environmental geosciences, geohydrology, environmental engineering and geotechnical engineering. It will also be valuable reading for graduate courses dealing with seismic wave propagation and related electromagnetic effects.

The book introduces all the aspects needed for the safe and economic design and analysis of connections using bolted joints in steel structures. This is not treated according to any specific standard but making comparison among the different norms and methodologies used in the engineering practice, e.g. Eurocode, AISC, DIN, BS. Several examples are solved and illustrated in detail, giving the reader all the tools necessary to tackle also complex connection design problems. The book is introductory but also very helpful to advanced and specialist audiences because it covers a large variety of practice demands for connection design. Parts that are not taken to an advanced level are seismic design, welds, interaction with other materials (concrete, wood), and cold formed connections.

Founded in 1928 as a “living diary” by the great Milanese architect and designer Gio Ponti, domus has been hailed as the world’s most influential architecture and design journal. With style and rigor, it has reported on the major themes and stylistic movements in industrial, interior, product, and structural design.This fresh reprint of the 1970s domus coverage brings together the most important features from an era marking seismic changes in architecture and design. It was a time when individualism gained momentum as a novel style, and we began to notice the first postmodernist tendencies. Faced with the global energy crisis, architects and designers imbued their methods with a new ecological awareness. For work to be featured in the magazine it had to offer function, spatial clarity, intellectual persuasion, relevant originality, and/or grace. Those groundbreaking projects and practitioners that made the cut include Shiro Kuramata, Verner Panton, Joe Colombo, Richard Meier, the modernist structures by Foster Associates and the Centre Georges Pompidou by Renzo Piano and Richard Rogers.domus distilledSeven volumes spanning 1928 to 1999Over 4,000 pages featuring influential projects by the most important designers and architectsOriginal layouts and all covers, with captions providing navigation and contextIntroductory essays by renowned architects and designersEach edition comes with an appendix featuring texts translated into English, many of which were previously only available in ItalianA comprehensive index in each volume listing both designers’ and manufacturers’ names.

Published by the American Geophysical Union as part of the Special Publications Series. Tectonic, Climatic, and Cryospheric Evolution of the Antarctic Peninsula presents the analysis of data collected during the SHALDRIL program, which sampled the most complete Cenozoic stratigraphic section in the Antarctic Peninsula. The stratigraphic intervals sampled fill major gaps in the existing stratigraphic record in the region, which is believed to have been the last place in Antarctica to become fully glaciated and, as such, the last refugium for plants and animals living on the continent. Providing previously unpublished results from studies aimed at improving our understanding of the changes in climate, glacial setting, and fauna and flora that took place over the past 30 million years, the volume highlights include discussions of marine seismic and drill core records documenting the initial growth and expansion of an ice sheet across the northernmost Antarctic Peninsula continental shelf in the northwestern Weddell Sea. The book features: Detailed vegetation and phytoplankton evolution from greenhouse through icehouse conditions in Antarctica's last refugium Sand grain texture and micromorphology indicating ice sheet control of weathering style Exhumational history around the Drake Passage margins from thermochronology and sediment provenance Comprehensive review of the opening of the ocean passageway between Antarctica and South America and the associated regional tectonics. Tectonic, Climatic, and Cryospheric Evolution of the Antarctic Peninsula will be of interest to geologists, climatologists, and glaciologists interested in climate and cryosphere evolution and those factors that regulate it.

In this important book, one of Latin America’s foremost critical theorists examines the use and abuse of memory in the wake of the social and political trauma of Pinochet’s Chile. Focusing on the period 1990–2015, Nelly Richard denounces the politics and aesthetics of forgetting that have underpinned both the protracted transition out of dictatorship and the denial of justice to its survivors and victims. What are the perils and social costs of a culture of forgetting? What forms do memories of injustice take in newly formed democracies? How might a history of violence and an ethics of reparation be reconciled in post-autocratic societies? In addressing these and other questions, Richard exposes the abuses of the past and the present while also attending to the residues of memory that are manifested in street protests, literature, and the media, and in artistic practices from architecture and urban design to installation and film. While cultural artifacts can be powerful devices for resistance and critique, Richard argues that they can also be complicit in reproducing and collaborating with forms of institutional and political oblivion. Both within Chile and beyond, Richard offers a trenchant critique of how authoritarian regimes and neoliberal states whittle away at memory’s critical capacity. At a time of seismic political realignments in Latin America and internationally, Eruptions of Memory makes a powerful case for the ethical, political, and aesthetic value of memory.
