This course builds on GL5015/5515 (Introduction to petrophysics and its role in the oil and gas industry). Students will learn how to integrate real log and core datasets to fully describe the variation in reservoir properties and how they may be distributed in oil and gas wells. Relating wireline data to core is important, as core analysis provides the only direct and quantitative measurement of the intact reservoir properties and provides essential calibration data for reliable formation evaluation. This course provides students with a solid grounding in the acquisition and evaluation of routine (RCA) and special (SCAL) core analysis datasets.
