Biographical Sketch: 

Turgay Ertekin has had extensive experience with the development and application of fluid flow models in porous media. He has been deeply involved in the mathematical modeling of flow problems using various techniques for 40 years. He has taught courses in fluid flow dynamics in porous media at the graduate and undergraduate levels and has directed the research work of graduate students on reservoir modeling and reservoir engineering. His research efforts with his graduate students have produced 45 Ph.D. and 95 M.S. theses, while 6 M.S. and 14 Ph.D. students' research works are still in progress. Ertekin has given more than 300 invited lectures, paper presentations and seminars and more than 30 workshops and short courses throughout the world, and has authored or co-authored more than 250 publications including four books and four book chapters. Ertekin has served on the Society of Petroleum Engineers Editorial Board holding various positions including a two-year term as the Executive Editor of the Formation Evaluation Journal and currently is an editor-in-chief of the Journal of Petroleum Exploration and Technology.

B.Sc. (Petroleum Engineering), Middle East Technical University, 1969

Research Interests: 
  • Advanced reservoir simulation models
  • Artificial expert system applications in reservoir engineering
  • Coalbed methane degasification
  • Pressure transient analysis applications in complex reservoir systems
  • Unconventional gas and oil reservoirs
Active Research Projects: 

Turgay Ertekin's current research deals with the flow of gases in unconventional gas reservoirs, coal seam degasification process, well test analysis for composite reservoirs, enhanced oil recovery techniques, artificial neural network applications in petroleum and natural gas engineering, and reservoir characterization. Over the course of years, Ertekin and his research groups have developed several multiphase, compositional, multidimensional isothermal and nonisothermal numerical flow models that simulate the performance and applicability of some thermal and nonthermal recovery techniques in petroleum reservoirs.
