Course Description
Well logging is an important procedure once a borehole has been drilled. This course will impart knowledge of geological and geophysical techniques of logging in order to study the subsurface properties of rocks.
Learning Outcomes
At the end of the course students should be able to
• Describe and explain geological and geophysical techniques of logging of boreholes.
• To describe methods used in logging while drilling.
• To interpret various petrophysical logs in terms of petrophysical properties and facies analysis.
Course Content:
Rock physics, physical properties of rocks: permeability, porosity, density, maganetic susceptibility, elastic properties and resistivity. Review of drilling methods in oil exploration, principles of well logging, formation evaluation, Lithological logging of well cuttings and core. Lithology and grain size analysis. dipmeter logging. Petrophysical logging: self potential, radiometric logging: natural gamma, neutron-gamma logging, gamma ray density logs, sonic logging, temperature logging, nuclear magnetic resonance. Integrated interpretation of various geophysical logs.
Delivery: 30 hours of lectures, 15 hours of Tutorials.
