Petrophysics for CCS

Course summary

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 CCS stream also explores the petrophysical monitoring of CO2 before considering how pulsed neutron logging can integrated into the CCS petrophysical toolkit. It concludes by discussing capillary pressure determination. 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 for CCS.

Learning outcomes

  1. Understand the measurement principles and integration of data obtained from openhole logging, mudlogging and core analysis
