Phase Behavior of Petroleum Reservoir Fluids

Karen Schou Pedersen earned a PhD in liquid physics at the Technical University of Denmark. Her work with liquids at a fundamental level continued in positions as a research associate at the University of Edinburgh and at the nuclear research center Institute Laue-Langevin, Grenoble, France. She founded Calsep A/S in 1982, worked for Calsep as a senior principal consultant until 2022, and was responsible for software development and projects within reservoir fluid modeling and flow assurance. She is the author of more than 60 publications on the phase behavior of oil and gas mixtures. Her current position is Senior Principal Consultant at Kapexy Aps, a company specializing in reservoir fluid modeling. Peter Lindskou Christensen earned a PhD at the Technical University of Denmark. In the 1980s, he was employed at Risø National Laboratories in Denmark, where he was responsible for PVT modeling for use in reservoir simulation studies. For a 10-year period in the 1990s, he was an associate professor at the Technical University of Denmark and taught thermodynamics, unit operations, and oil and gas technology. After leaving the university, he became a senior principal consultant at Calsep A/S, where he developed new techniques for matching experimental PVT data and was engaged in several fluid modeling projects. Peter is today a senior consultant at Kapexy Aps. Jawad Azeem Shaikh earned an MSc in petroleum technology at the University of Pune in India. His current position is Sales Director and Principal Consultant of Calsep FZ LLC in Dubai where he has been responsible for several projects carried out in collaboration with the local oil industry within the design of enhanced oil recovery studies, equation of state modeling, and reservoir fluid communication. Before joining Calsep, he was an advanced studies supervisor for Core Laboratories International BV in Abu Dhabi. His job functions at Core Laboratories included technical support to field engineers to carry out fluid sampling as well as project coordination and data evaluation within PVT, compositional, and enhanced oil recovery projects. He has authored several papers and articles on sampling, PVT lab work, fluid communication, and equation of state modeling.
