Short Bio

Christos Chatzichristos was born in Larisa-Greece (1966) and studied Mining and Metallurgy Engineering at the Technical University of Athens (1990). He obtained his PhD in Petroleum Engineering in 1996 (Dept. of Petroleum Engineering, Heriot Watt University, UK). In 1997, he was employed as a temporary Lecturer in the University of Crete teaching Drilling Engineering. In 1998, he joined the Institute for Energy Technology, Dept. of Reservoir Technology (IFE, Norway), initially as a Marie Curie grant-holder and later as a Senior Scientist. In 2005, he joined the Institute of Nuclear Technology & Radiation Protection at the National Center of Scientific Research "Demokritos" as a Postdoc Fellow and belongs to the permanent scientific staff of the Institute from 2007. Over the years he has built his expertise in reservoir simulation, reservoir characterization and reservoir monitoring. He has worked for more than 30 fields worldwide (North Sea, South America, West & North Africa, Persian Gulf and Southeastern Asia) and collaborated with many field operators: Statoil, Conoco-Philips, Norsk Hydro, BP, Total, CEPSA, Wintershall.

Presentation Title: Tracer Technology for Improved Reservoir Description


Tracers are chemical substances that are applied in minor quantities in a process to keep track on fluid flow. They are ideally inert compounds, which follow only the fluid under investigation. They are used widely by the oil industry for reservoir monitoring and improved reservoir description. Interwell tracer tests are carried out in order to establish the well-to well communication and to monitor the Secondary or Tertiary recoveries. Push n’ Pull Single Well Tracer Tests are carried out to measure The Residual Oil Saturation in order to evaluate the effectiveness of the EOR applications.
