On Friday 01.03.2019 Prof. Vassilios Kelessidis visited our University for the first scheduled seminar of 2019: "Drilling optimization revisited: How close are we to drilling optimization while drilling (DOWD)?"

Dr. Kelessidis made it through all ranks in Mineral Resources Engineering Department at Technical University of Crete between 2000-2016.He was for four years  (2012-2016) at Texas A&M at Qatar, as Program Chair (2 years) and Professor of Petroleum Engineering. He joined Petroleum Engineering at Khalifa University in Abu Dhabi in January 2017- December 2018 as a Professor and Department Chair. 

Dr. Kelessidis has worked for over 9 years with different Schlumberger companies in Houston, France and England, working on drilling fluid issues, surface logging, kick control, cementing operations, drilling hydraulics, drilling optimization.

His main research interests are on, drilling engineering, drilling optimization, cuttings transport, drilling fluid development, drilling fluid rheology, formation damage, studying rock-bit interaction, and on new cement formulation. His activities extend to rock typing and understanding rock petrophysical properties and interaction of rock surfaces with formation fluids and mud filtrates and to fluid mechanics and multiphase flows.

He has 41+ journal and 62+ refereed conference papers, more than 1110 citations and h-index of 18. He is leading author of Chapter 5 – Drilling Hydraulics, in ‘Fundamentals of Drilling Engineering’ edited by: Mitchell Miska in 2011 (SPE Textbook Series). He is Associate Editor in SPE Drilling and Completion Journal since October 2016 and September 2019- June 2020, SPE Distinguished Lecturer.
