Petrophysics - SP003
Petrophysics Tools for Geoscience
This course builds a working understanding of the common openhole logging tools and measurements used in traditional petrophysical analysis; the measurement principles and the main qualitative and quantitative aspects of their analysis are considered for each individual log type. This geoscience stream also explores how openhole logs can be used to interpret facies, depositional environment, and sequence stratigraphy. It concludes by introducing dipmeter and borehole image logs for geological interpretation. In combination with the Foundation course, the overarching objective is to increase familiarity with the language, concepts and tools used in the field of petrophysics and their geological interpretation.
- Understand the measurement principles and integration of data obtained from openhole logging, mudlogging and core analysis
- Describe the principles and measurements of traditional openhole logs; Gamma Ray, Spontaneous Potential, Bulk Density, Neutron, Sonic, Nuclear Magnetic Resonance, and Resistivity logs
- Determine shale volume, porosity and water saturation from these traditional openhole logs
- Consider how openhole logs can be used to interpret sedimentary facies, depositional environment, and sequence stratigraphy
- Understand the measurement principles and geological interpretation of dipmeter and borehole image logs.
