Book Description
The measurement of some of the physical properties of the soils and rocks penetrated by bore holes provides information of value to the soil engineer. Electrical resistivity, radiation, and acoustical properties are particularly useful. The measurements continuously recorded in terms of depths give a detailed log on which geological and physical changes are indicated. In a typical case, the field operations are conducted as follows: (1) A small number of test wells scattered over the area of interest are drilled, cored, and logged with one or several appropriate probes; (2) additional holes are then drilled between the test wells; and (3) these holes are logged but not cored. By correlating the logs and the core data the geology of the area and some of the rock properties can be mapped. None of the methods reviewed, however, can be used to measure dynamic properties. The main advantages of geophysical logs are that detailed information is readily obtained at the well sites and at a lower cost than if each hole were cored. The equipment used for the logging of shallow holes is small, light, rugged and simple. No special technician is needed for its operation.

Book Description
The first edition of this book demystified the process of well log analysis for students, researchers and practitioners. In the two decades since, the industry has changed enormously: technical staffs are smaller, and hydrocarbons are harder to locate, quantify, and produce. New drilling techniques have engendered new measurement devices incorporated into the drilling string. Corporate restructuring and the "graying" of the workforce have caused a scarcity in technical competence involved in the search and exploitation of petroleum. The updated 2nd Edition reviews logging measurement technology developed in the last twenty years, and expands the petrophysical applications of the measurements.

Book Description
Proceedings of an International Symposium and Workshop on Borehole Geophysicsfor Mining and Geotechnical Applications, held in Toronto in August 1983. The contents include 41 papers and summaries of two afternoon workshops oninstrumentation and on interpretation and are arranged in order ofpresentation, in groups of papers on logging applications, calibrationaspects, EM methods, applied potential methods, acoustic methods, magneticborehold radar, magnetometric resistivity, gravity, x-ray and other nuclearmethods. The five papers from the earlier 1981 Geological Survey of CanadaMineral Logging Workshop concern inverse filtering of gamma ray logs, borehole IP, EM, resistivity and seismic measurements, and log calibrationand quality control.

Book Description
Geotechnical investigation, which is usually implemented to obtain baseline information of ground and groundwater, is the focus of this book. Authored by practitioner and academic who is extensively involved in geotechnical ground investigations over four continents, this book covers both large scale preliminary ground investigation and intrusive detailed investigation, as well as specialized in-situ testing to obtain advanced geotechnical parameters of soils. Both surface and borehole geophysical methods used in geotechnical investigation, including methods of sampling and tools to obtain good quality soil samples are also discussed and presented in the book.Written for advanced undergraduate and graduate students, researchers and practitioners in the fields of geotechnical engineering, geoenvironmental engineering, and ground investigation, the book also provides guidelines on presenting factual geotechnical data and preparing factual reports.Related Link(s)

Book Description
The scope of engineering seismology includes geotechnical site investigations for buildings and engineering infrastructures, such as dams, levees, bridges, and tunnels, landslide and active-fault investigations, seismic microzonation, and geophysical investigations of historic buildings. These projects require multidisciplinary participation by the geologist, geophysicist, and geotechnical and earthquake engineers. A key objective of this book (SEG Investigations in Geophysics Series No. 17) by Öz Yilmaz is to encourage the specialists from these disciplines to apply the seismic method to solve the many challenging engineering problems they face. The broader scope of engineering seismology also includes exploration of earth resources, including groundwater exploration, coal and mineral exploration, and geothermal exploration. While focusing on the application of the seismic method to geotechnical site investigations, this book includes many case studies in all of the applications of engineering seismology.
