This dissertation addresses recurrent questions in hydrocarbon reservoir characteri¬zation. In particular, the major focus of this research volume is microtextural characterization of source rock fabric as well as elastic and transport properties of source rocks. Source rocks are one of the most complicated and intriguing natural materials on earth. Their multiphase composition is continually evolving over various scales of length and time, creating the most heterogeneous class of rocks in existence. The heterogeneities are present from the submicroscopic scale to the macroscopic scale, and all contribute to a pronounced anisotropy and large variety of shale macroscopic behavior. Moreover, the effects of the multiphase composition are amplified within organic-rich rocks that contain varying amounts of kerogen. Despite significant research into the properties of kerogen, fundamental questions remain regarding how the intrinsic rock-physics properties of the organic fraction affect the macroscopic properties of host rocks. Because we do not fully understand the elastic properties of either the organic matter or the individual clay minerals present in source rocks, seismic velocity prediction in organic-rich shales remains challenging. Conventional measurements of 'macroscopic' or 'average' properties on core plugs are not sufficient to fully address the degree of property variation within organic-rich rocks. Alternatively, most analyses of organic matter rely on samples that have been isolated by dissolving the rock matrix. The properties of the organic matter before and after such isolation may be different, and all information about sample orientation is lost. In addition, comprehensive characterization of organic-rich rocks has been hindered by several factors: sample preparation is time-consuming, and the nanogranular nature of this rock type makes it difficult to link effective elastic properties to maceral properties, such as elastic moduli, composition, maturity, and quality. These difficulties have prevented us from building large databases, without which we cannot establish the accurate rock-physics models needed for inverting field geophysical data. I approach this issue using atomic-force microscopy based nanoindentation, coupled with scanning electron and confocal laser-scanning microscopy as a tool for visualization and identification of the organic part within shale, and to perform nanoscale elastic-property measurements. First, the microfabric of a set of source rock samples is characterized. The spatial and temporal link between organic matter and the stiff silicate mineral matrix is established, which leads to proposal of alternative Rock Physics modeling approach to organic-rich source rocks. Based on the nanoindentation measurements, I obtain elastic properties of source rock phases and provide several applications of these (nanoindentation-derived) elastic properties within a number of geomechanical problems. Finally, transport properties of various source rock formations are discussed based on comparison to more conventional reservoir rocks.

More often than not, it is difficult or even impossible to obtain directly the specific rock parameters of interest using in situ methods. The procedures for measuring most rock properties are also time consuming and expensive. Engineering Properties of Rocks, Second Edition, explores the use of typical values and/or empirical correlations of similar rocks to determine the specific parameters needed. The book is based on the author's extensive experience and offers a single source of information for the evaluation of rock properties. It systematically describes the classification and characterization of intact rock, rock discontinuities, and rock masses, and presents the various indirect methods for estimating the deformability, strength, and permeability of these components as well as the in situ rock stresses. - Presents a single source for the correlations on rock properties - Saves time and resources invested on in situ testing procedures - Fully updated with current literature - Expanded coverage of rock types and geographical locations

Volume 87 of Reviews in Mineralogy and Geochemistry covers fundamental aspects of the nature of silicate melts and the implications for the systems in which they participate, both technological and natural. The contents of this volume may perhaps best be summarized as structure – properties – dynamics. The volume contains syntheses of short and medium range order, structure-property relationships, and computation-based simulations of melt structure. It continues with analyses of the properties (mechanical, diffusive, thermochemical, redox, nucleation, rheological) of melts. The dynamic behavior of melts in magmatic and volcanic systems, is then treated in the context of their behavior in magma mixing, strain localization, frictional melting, magmatic fragmentation, and hot sintering. Finally, the non-magmatic, extraterrestrial and prehistoric roles of melt and glass are presented in their respective contexts.

Leroy: An Introduction to the Finite-Element Method for Linear and Non-linear Static Problems. The mechanical behaviour of the earth's upper crust enters into a great variety of questions in different areas of the geological and geophysical sciences as well as in the more applied geotechnical disciplines. This volume presents a selection of papers from a CISM course in Udine on this topic. While each of these chapters will make for a useful contribution in its own right, the present bundle also illustrates, by way of examples, the variety of theoretical concepts and tools that are currently brought to bear on earth deformation studies, ranging from reviews of poroelastic field theory to micro-mechanical and homogenization studies, chemomechanics and interfacial stability theory of soluble solids under stress, and finally to an introduction to the finite element method.

Rock microstructures provide clues for the interpretation of rock history. A good understanding of the physical or structural relationships of minerals and rocks is essential for making the most of more detailed chemical and isotopic analyses of minerals. Ron Vernon discusses the basic processes responsible for the wide variety of microstructures in igneous, sedimentary, metamorphic and deformed rocks, using high-quality colour illustrations. He discusses potential complications of interpretation, emphasizing pitfalls, and focussing on the latest techniques and approaches. Opaque minerals (sulphides and oxides) are referred to where appropriate. The comprehensive list of relevant references will be useful for advanced students wishing to delve more deeply into problems of rock microstructure. Senior undergraduate and graduate students of mineralogy, petrology and structural geology will find this book essential reading, and it will also be of interest to students of materials science.
