Dr. Hassan Eltom
Assistant Professor, Department of Geosciences
Dr. Eltom is an Assistant Professor at the Department of Geosciences. His research focuses on carbonate sedimentology, chemostratigraphy, sequence stratigraphy, and diagenesis, the processes that control the quality of hydrocarbon reservoirs. His major area of interest is to understand pore system in carbonate reservoirs, particularly carbonate with complex large pores (cavern, vuggy, breccia, and burrow porosity). Dr. Eltom interdisciplinary research integrates geological, geophysical, petrophysical, geostatistical, and reservoir simulation data to quantitatively address questions regarding controls on flow properties of carbonate with large pores. Dr. Eltom has several publications in refereed journals and conferences. He worked with Schlumberger overseas as a geologist for four years (2006 – 2010), with KFUPM as lecturer and researcher for four years (2010 – 2014), and with Kansas Interdisciplinary Carbonates Consortium (KICC) – the University of Kansas as Post-doc for five years (2014 – 2019).
