This course provides an introduction to magnetic and subsurface methods for geophysical exploration. An overview of the spectrum of geophysical exploration methods is provided followed by more detailed discussions of magnetic and subsurface methods. Magnetic issues discussed include magnetometers, field intensities and subsurface metals. Subsurface methods discussed include in-hole logging, log analysis, borehole effects, spontaneous potential logging, single point resistance logging, normal resistivity logging, lateral resistivity logging, focused resistivity logging, dipmeter logging, induction logging, nuclear logging, gamma logging, gamma-gamma logging, neutron logging, acoustic logging, acoustic wave-form logging, cement-bond logging, acoustic televiewer logging, caliper logging, temperature logging, conductivity logging, flow logging, hydrophysical logging, and casing logging. Course Outline 1. INTRODUCTION 2. GEOPHYSICAL METHODOLOGY 3. MAGNETIC METHODS 4. SUBSURFACE GEOPHYSICAL METHODS This course will give environmental, geotechnical and civil engineers and other design and construction professionals an introduction to geophysical exploration methods using subsurface and magnetic techniques.
