The Gold-Standard “Bible” for Applied Subsurface Geological Mapping: Extensively Updated for Working Teams’ Latest Advances Long recognized as the most authoritative, practical, and comprehensive guide to structural mapping methods, Applied Three-Dimensional Subsurface Geological Mapping, Third Edition, has been thoroughly updated to reflect recent technical developments, with an emphasis on shale play basins, horizontal drilling, unconventional resources, and modern workflows. The authors of this edition have more than a century of collective experience in hydrocarbon exploration and development, in major, large, independent companies throughout the world. In this long-awaited update, they present revised and new chapters on computer mapping, shale basin exploration, and prospect reserves and risk. They introduce key innovations related to shale reservoirs, hydraulic fracturing, and deviated, horizontal, and directional wells, along with expanded discussions of computer interpretations and mapping. Throughout, the book links theory and practice based on fundamental geoscience principles. These principles will help you integrate all available geological, geophysical, and engineering data, to generate more reasonable and viable subsurface interpretations, and to construct maps that successfully identify reserves. Master core principles and proven methods for accurate subsurface interpretations and mapping Construct subsurface maps and cross-sections from well logs, seismic sections, and outcrop data Work effectively with horizontal and directionally drilled wells and directional surveys Use powerful well log-correlation techniques Construct viable fault and horizon structure maps Balance and interpret compressional, extensional, and strike-slip structures Distinguish between the different structure styles and the characterization of growth structures Understand isochore and isopach maps This book is indispensable for every integrated working team, consisting of geologists, geophysicists, and engineers, that prepares subsurface geological interpretations and maps, as well as for every manager, executive, and investor who uses or evaluates prospects.

Applied Subsurface Geological Mapping, With Structural Methods, 2nd Edition is the practical, up-to-the-minute guide to the use of subsurface interpretation, mapping, and structural techniques in the search for oil and gas resources. Two of the industry's leading consultants present systematic coverage of the field's key principles and newest advances, offering guidance that is valuable for both exploration and development activities, as well as for "detailed" projects in maturely developed areas. Fully updated and expanded, this edition combines extensive information from the published literature with significant material never before published. The authors introduce superior techniques for every major petroleum-related tectonic setting in the world. Coverage includes: A systematic, ten-step philosophy for subsurface interpretation and mapping The latest computer-based contouring concepts and applications Advanced manual and computer-based log correlation Integration of geophysical data into subsurface interpretations and mapping Cross-section construction: structural, stratigraphic, and problem-solving Interpretation and generation of valid fault, structure, and isochore maps New coverage of 3D seismic interpretation, from project setup through documentation Compressional and extensional structures: balancing and interpretation In-depth new coverage of strike-slip faulting and related structures Growth and correlation consistency techniques: expansion indices, Multiple Bischke Plot Analysis, vertical separation versus depth, and more Numerous field examples from around the world Whatever your role in the adventure of finding and developing oil or gas resources–as a geologist, geophysicist, engineer, technologist, manager or investor–the tools presented in this book can make you significantly more effective in your daily technical or decision-oriented activities.

The book includes new material, in particular examples of 3-D models and techniques for using kinematic models to predict fault and ramp-anticline geometry. The book is geared toward the professional user concerned about the accuracy of an interpretation and the speed with which it can be obtained from incomplete data. Numerous analytical solutions are given that can be easily implemented with a pocket calculator or a spreadsheet.

Geologic maps supply a wealth of information about the surface and shallow subsurface of the earth. The types of materials that are present in a location and the three-dimensional structure of the bedrock both can be gleaned from a clearly prepared geologic map. Geologists, civil and environmental engineers, land-use planners, soil scientists, and geographers commonly use geologic maps as a source of information to facilitate problem solving and identify the qualities of a region. Maps reveal the position of many types of natural hazards, indicate the suitability of the land surface for various uses, reveal problems that may be encountered in excavation, provide clues to the natural processes that shape an area, and help locate important natural resources. Suitable for lab courses in structural geology as well as field geology work, Spencer describes representative examples of features found on geologic maps and outlines procedures for interpretation and projection. Geometric techniques are explained using a step-by-step approach. Coverage of mapping methods includes tools that provide necessary data, such as Google Earth, GPS, GIS, LiDAR maps, drones, and aerial photographs. Challenging and engaging exercises throughout the text involve students in the mapping process and stimulate an appreciation of the extent and precision of information presented in geologic maps. Regional geology is an important component of lab and field mapping projects. As such, the Third Edition includes new maps of the Gulf of Mexico Coastal Plain, Rocky Mountain Front Range, Yellowstone region, Moab, Utah, Shenandoah National Park, and Hawai’i. A new chapter devoted to tectonic maps also broadens students’ exposure. Ed Spencer brings over 45 years of teaching experience to the text along with valuable insight and clarity into the interpretation and preparation of geologic maps.
