Developed by three experts to coincide with geology lab kits, this laboratory manual provides a clear and cohesive introduction to the field of geology. Introductory Geology is designed to ease new students into the often complex topics of physical geology and the study of our planet and its makeup. This text introduces readers to the various uses of the scientific method in geological terms. Readers will encounter a comprehensive yet straightforward style and flow as they journey through this text. They will understand the various spheres of geology and begin to master geological outcomes which derive from a growing knowledge of the tools and subjects which this text covers in great detail.
This book offers a compact guide to geological core analysis, covering both theoretical and practical aspects of geological studies of reservoir cores. It equips the reader with the knowledge needed to precisely and accurately analyse cores. The book begins by providing a description of a coring plan, coring, and core sampling and continues with a sample preparation for geological analysis. It then goes on to explain how the samples are named, classified and integrated in order to understand the geological properties that dictate reservoir characteristics. Subsequently, porosity and permeability data derived from routine experiments are combined to define geological rock types and reduce reservoir heterogeneity. Sequence stratigraphy is introduced for reservoir zonation. Core log preparation is also covered, allowing reservoirs to be analysed even more accurately. As the study of core samples is the only way to accurately gauge reservoir properties, this book provides a useful guide for all geologists and engineers working with subsurface samples.
Characterizing the in-place conditions of rock masses commonly depends upon continuous diamond-core drilling for site investigation or resource characterization. However, because of incomplete or inconsistent core descriptions, potentially valuable information may be lost or unavailable for other users. This situation suggested the potential value of photographic core-logging manuals and descriptive codes to facilitate consistency in core description and ease in the transfer and computerization of these descriptions. To that end, this article describes the development of such manuals and codes using the U.S. eastern gas and oil shales as examples. Although the described manual was developed specifically for these rocks because of their energy-related significance, the concept and coding scheme are readily applicable to core description for all types of engineering and geological purposes.
