HALBAN As part of a student lecture tour organized by the European Association of Geoscientists and Engineers (EAGE), Prof. Dr. John D. Humphrey, King Fahd University of Petroleum & Minerals, will give a lecture on “understanding carbonate mudrocks”. The lecture will be held next Monday at GUtech. “We are looking forward to an interesting talk by an internationally renown carbonate rock specialist. Carbonate mudrocks are of specific interest to Oman and the wider region as source rocks for oil and gas. Prof. Humphrey has been extensive teaching, research and consultancy experience within the oil and gas and mining industries,” said Prof. Dr. Wilfried Bauer, Head of the Department of Applied Geosciences at GUtech.

Fine-grained, mud-dominated, carbonate rocks can form in a variety of sedimentary environments. While sub-environments of shallow-water tropical carbonate systems are capable of producing muddy facies, this talk focuses on predominantly pelagic carbonates in slope and basin settings. Increasingly, such carbonate mudrocks are becoming the targets of unconventional petroleum system exploration and development. Basinal accumulations of pelagic carbonate (either platform or open ocean derived) can be associated with anoxic to suboxic conditions conducive to preservation of marine organic matter. These organic-rich carbonate mudrocks tend to be brittle and are therefore viable targets for hydraulic fracturing completions. Other carbonate mudrock systems are economically important conventional reservoirs, such as the Upper Cretaceous to Paleogene chalks of the North Sea.

The lecture will consider the sedimentology and diagenesis of pelagic carbonates, including ecological controls on carbonate production, chemical controls on carbonate accumulation, and the effects of burial diagenesis on carbonate mudrock reservoir quality. Case studies of mudstone/chalk reservoirs will be presented.

Dr. John D. Humphrey is Associate Professor and Assistant Chairman of Geosciences at King Fahd University of Petroleum and Minerals. His appointment is in the Department of Geosciences, within the College of Petroleum Engineering and Geosciences. His areas of specialization include carbonate diagenesis and geochemistry, carbonate sedimentology and stratigraphy, carbonate reservoir characterization, unconventional carbonate reservoirs, stable isotope geochemistry, and paleoclimatology. He has been a consultant to the oil and gas and mining industries for thirty years. Dr. Humphrey is a Fellow of the Geological Society of America and a Trustee Associate of the American Association of Petroleum.

Prof. Humphrey received his B.S. degree in Geology at the University of Vermont, where he was elected to Phi Beta Kappa and graduated Cum Laude. Dr. Humphrey received his M.Sc. and Ph.D. degrees from Brown University in Geological Sciences. He was on the faculty of Geosciences at the University of Texas at Dallas from 1986 to 1991. Beginning in 1991, Dr. Humphrey was a professor of Geology and Geological Engineering at Colorado School of Mines. He was twice awarded the Alumni Teaching Award for the top educator at CSM (1998, 2014). He served as Department Head from 2006 to 2013. From 2013 to 2015, he was Interim Director of the CSM Chevron Center of Research Excellence. He retired from Mines in 2015 and joined KFUPM in 2017.
