This book is devoted to the most important and urgent problems arising during the operation of underground gas storage facilities (UGS) and associated with the destruction of the reservoir and sand production into the wells. UGS facilities play a special role in ensuring high reliability of stable and guaranteed gas supplies to consumers. However, despite many years of experience in UGS well operation, there is still no sufficiently substantiated geomechanical model of reservoir failure and a mathematical description of the processes occurring in the reservoir-well system, taking into account the peculiarities of the mechanical behavior of reservoir rocks during cyclic injection and extraction of gas. As a result, there are no reliable criteria for establishing a rational regime for the operation of an UGS wells in conditions of a possible destruction of reservoir rocks. Further development of underground gas storage direction requires the introduction of innovative technologies that can be used both in the design of new UGS facilities and to extend the safe and efficient operation of existing underground gas storage facilities. To solve these problems, the most promising technologies, taking into account their efficiency, relatively low cost and environmental safety, are those based on the geomechanical approach.The book is addressed to specialists in the development and operation of underground gas storage facilities, as well as specialists in geomechanics of oil and gas fields. It can be useful for students and graduate students studying in the speciality "Development of oil and gas fields".

The book addresses the issues of the channel evolution in neotectonically active domains of India. It aims at readers of India as well as abroad, interested in earth sciences, geomorphology, tectonics, physical geography and river forms and processes of India. 

From earthquakes to the northern lights and tsunamis to glacier movement, the author explains thousands of phenomena in the world around us. All of this is done using language that is simple and understandable, and at the same time this book does not try to deceive the reader, as materials of this nature often do, but uses exact physical formulas where they are needed.This book serves as an invaluable reference for physics teachers and should inspire high school students to study physics. Many of them will very likely be able to understand that riveting events and phenomena lie behind those very same formulas that just yesterday seemed so boring.This is an excellent and unique way of easily submerging oneself into the world of science and a non-stop intellectual challenge that lures the reader in much more than any game of chess.Sir Andre Geim, 2010 Nobel Prize Laureate in PhysicsThere are plenty of high school students who continue to find science interesting today. Dmitry Livanov¿s book, which is both useful and held in high regard, is written precisely with these young people in mind.This book can be used by teachers who want to expand the narrow scope of subject material in their classes and enable students to broaden their perspective about how to apply the laws of physics in order to understand such a complex natural object as planet Earth. This book will be of interest to high school students and graduates of high schools, specialized high schools and preparatory schools who want to test their understanding of physics, astronomy and geography. This book strengthens the foundation of scientific knowledge in today¿s world, which repeatedly tests the strength of the collective body of science.Evgeniy Yamburg,Member of the Russian Academy of EducationPrincipal, School #109, Moscow Dmitry Livanov was able to write a book thatis interesting both for those who are just beginning to become familiar with physics, and for those who for various reasons have forgotten much of what they knew at one time. He succeeded in doing this because he himself knows and loves physics and because physics¿as the most important part of human culture¿is interesting to him.I hope that readers of this book will not only recognize the usefulness and importance of physics, but also appreciate its beauty and allure.Andrey Furchenko,Doctor of Physics and Mathematics,Aide to the President of the Russian Federation

This book presents the first report and interpretation of the deformation, structural style, and geo-tectonic evolution of a 600km2 area of the Ladakh batholith, NW India, centred on the city of Leh, Ladakh. The Ladakh (and westerly Kohistan ) batholith comprises a large component of the Jurassic-Oligocene Kohistan-Ladakh Arc-Terrane (KLA), with magmatism spanning island arc, continental margin, and post-Himalayan collision tectonic environments. The KLA is bounded to the north by the Shyok-Northern Suture and to the south by the Indus Suture. The batholith illustrates basement thick-skin tectonic deformation and is divided/partitioned into a series of crustal blocks separated by lateral accommodation structures which allow independent movement in horizontal and vertical space. Thin skinned deformation within the adjacent sedimentary molasse Indus Suture Rocks produced large thrust stacks that predominantly moved towards the N-NE. Whilst deformation within cover sequences influences the basement structures, and helps break up the basement into crustal blocks, there is a clear distinction in deformation between the basement and cover sequences. Basement batholith deformation is more complex and heterogeneous, reflecting the variable transmission of tectonic stress within crystalline crust and the presence of a wide range of precursory inherited weaknesses and anisotropies. Models of time-space deformation are presented using data derived from field and extensive photograph / photo-mosaic image interpretation. The batholith was deformed during at least Palaeocene-Pliocene times at crustal depths that correspond to the ductile-brittle transition zone and shallower.

The study of vortex and wave flows is one of the traditional problems of fluid mechanics, the practical importance of which has grown significantly in recent years. Consideration of the processes of substance transfer in such complex systems as natural water bodies is fraught with many difficulties of a methodological and fundamental nature: the extreme complexity of conducting a full-scale experiment, the complexity and variability of hydrophysical fields of the ocean and hydrometeorological conditions during research, and also, in some cases, the complexity and the variability of the properties of the transferred substance. In this connection, it is of particular interest to study the transfer of markers in stationary vortex and wave flows, which can form in laboratory facilities with constant external conditions. In this case, it is possible to avoid problems associated with the spatial and temporal variability of natural sources of vortex formations and directly trace the dependence of the characteristic flow parameters or the characteristics of the movement of solid or other objects placed during. This book presents the results of experimental and theoretical studies of the dynamics and structure of multiphase vortex flows and the nature of the transfer of three types of markers: solid-state (ice, plastic), immiscible with water (oil, oil, diesel) and soluble (aniline dyes, uranyl). The results will be important, first of all, for a better understanding of the behavior of various impurities in the circulation flows and more accurate prediction of their distribution in natural conditions (in a stratified hydrosphere and atmosphere).

One of today¿s major geoscientific controversies centres on the origin of the Archean granite¿greenstone terranes. Is the geology of these scattered remnants of our planet¿s early crust consistent with the theory that modern-style plate-tectonic processes operated from the early Archean, or does it indicate that tectonic and magmatic processes were different in the Archean? Earth has clearly evolved since its initial formation, so at what stage did its processes of crustal growth first resemble those of today? The logical place to seek answers to these intriguing and important questions is within the best-preserved early Archean crust. The Pilbara region of northwest Australia is internationally famous for its abundant and exceptionally well-preserved fossil evidence of early life. However, until recently the area has received much less recognition for the key evidence it provides on early Archean crustal evolution. This book presents and interprets this evidence through a new stage-by-stage account of the development of the Pilbaräs geological record between 3.53 and 2.63 Ga. The Archean Pilbara crust represents one fragment of Earth¿s oldest known supercontinent Vaalbara, which also included the Kaapvaal Craton of southern Africa. Recognition of Vaalbara expands the background database for both these areas, allowing us to more fully understand each of them.

This book addresses the problems of mathematical relations between global and classical coordinate references from the practical applications point of view. It presents a large cartographic and numerical information set, which provides great values for practical and academical use based on the classical Albanian coordinative reference (ALB1986/ALB1987). This information is reflected from the positional point of view in the new modern Albanian satellite reference ALBPOS (Albanian Positioning System) or ALBCORS (Albanian Continuous Operation Reference Stations System). The main purpose of this Monograph is to summarize coordinative references applied in Albania in different periods, both classical and modern. Relevant transformation models between traditional/classical reference ALB1986 / ALB1987 and GNSS satellite reference are presented. The book furthermore recommends the mathematical models of the relationship in plan and height, between the Albanian classical reference and the global/European coordinate references (ITRF, EUREF). It serves to professionals involved in fundamental geodetic works as well as all working with GNSS or developing GIS applications.

This book presents an easy-to-use tool for time series analysis and allows the user to concentrate upon studying time series properties rather than upon how to calculate the necessary estimates. The two attached programs provide, in one run of the program, a time and frequency domain description of scalar or multivariate time series approximated with a sequence of autoregressive models of increasing orders. The optimal orders are chosen by five order selection criteria. The results for scalar time series include time domain stochastic difference equations, spectral density estimates, predictability properties, and a forecast of scalar time series based upon the Kolmogorov-Wiener theory. For the bivariate and trivariate time series, the results contain a time domain description with multivariate stochastic difference equations, statistical predictability criterion, and information for calculating feedback and Granger causality properties in the bivariate case. The frequency domain information includes spectral densities, ordinary, multiple, and partial coherence functions, ordinary and multiple coherent spectra, gain, phase, and time lag factors. The programs seem to be unique and using them does not require professional knowledge of theory of random processes. The book contains many examples including three from engineering.
