Borehole Geophysics
Wireline logging measures physical properties along a borehole wall, trading the spatial coverage of surface methods for depth-registered detail. Combining logs (gamma, resistivity, sonic, neutron, density, caliper) turns a single hole into a calibrated column of lithology, porosity, and fluid content.
Learning Objectives
Undergraduate Core: By the end of this module, you will be able to:
- Match common environmental logging tools to their measured signal and investigation volume.
- Interpret gamma, induction, neutron, televiewer, nuclear magnetic resonance, fluorescence, and flowmeter responses jointly.
- Recognize borehole-fluid, casing, diameter, invasion, and tool-position effects.
- Separate a measured log response from a calibrated formation-property estimate.
Graduate Extension
Evaluate vertical resolution, environmental corrections, response-function mixing, petrophysical calibration, and joint interpretation with surface geophysics.
