Pressure Transient Analysis—From Past to Future

Erdal Ozkan


Pressure transient analysis was one of the most important reservoir characterisation tools when we had limited technologies and capabilities in the past. Today, despite the drastic changes in the ways we characterise reservoirs, pressure transient analysis remains to be one of the key technologies in our toolbox. This is because of the continuous adaptation of the pressure transient analysis theory and practice to the changing needs and the technological environment. This course presents the fundamental philosophy of pressure transient analysis, documents its progress in time, and explores its evolution into the future. A perspective of the capabilities pressure transient analysis offers for the characterisation of complex conventional and unconventional reservoirs is also provided.

Erdal Ozkan is a professor of Petroleum Engineering at the Colorado School of Mines. He is also the director of Unconventional Reservoir Engineering Project (UREP) Consortium and the co-director of the Marathon Center of Excellence for Reservoir Studies (MCERS). He has BS and MS degrees from Istanbul Technical University and a PhD degree from the University of Tulsa, all in Petroleum Engineering. He has over 25 years of teaching and research experience at Istanbul Technical University, University of Tulsa, and Colorado School of Mines.

Ozkan’s main research interests are reservoir engineering, modelling fluid flow in porous media, pressure transient analysis, unconventional reservoirs, and horizontal and multilateral well technology. He has presented and published over 100 papers, co-authored a book, and contributed to several others. Ozkan has been actively involved in the organisation of many technical conferences and served as the executive and associate editor of leading petroleum engineering journals, such as the SPE Reservoir Evaluation and Engineering, Journal of Petroleum Science and Engineering, Journal of Energy Resources Technology, and Journal of Natural Gas Science and Engineering. He also serves as a referee for several US and international research foundations. He was a member of the SPE Reservoir Description and Dynamics Advisory Committee and a Technical Director of the SPE Research and Development Technical Section.

Ozkan is the recipient of the SPE Lester C. Uren (2013) and Formation Evaluation (2007) awards. He is a Distinguished Member of the Society of Petroleum Engineers (SPE) and he served as an SPE Distinguished Lecturer on shale-gas reservoirs (2011-2012). He is also a member of the American Society of Mechanical Engineers (ASME) and Society of Industrial and Applied Mathematics (SIAM).
