Equation of State Primer - Historical Development of the Cubic EOS to Present Day Forms

Includes a Live Event on 07/12/2022 at 10:00 AM (EDT)

The development of the van der Waals (VDW) cubic equation of state (EOS) more than century ago was a watershed moment in the prediction of volumetric, thermodynamic and phase equilibrium properties of fluids. A brief account of the historical contributions to EOS development prior to VDW is offered. The equation proposed by Johannes Diderik van der Waals in his celebrated thesis presented in 1873 at the University of Leiden is then analyzed. A chronological walk through of the most important developments in cubic EOS from the early 1900s to present is summarized. The application of cubic EOS to mixtures and the development of mixing rules are briefly described. Finally, a critical discussion of various EOS parameters including model parameters, characterization parameters, and tuning parameters is presented.

While the VDW EOS provided a description of real gases and the transition to condensed liquid phase, its accuracy suffered beyond simple gases like helium or methane. Today's current form of cubic EOSs with multiple adjustable parameters could suffer a similar fate when applied "out-of -the-box" to complex mixtures at high-pressures, such as encountered with reservoir fluids.

The proper use of EOS in production measurement and allocation applications is currently being addressed in the development of API MPMS Ch. 20.4 - Phase Behavior Application in Upstream Measurement (of which the author was the founding chair and is now a working group member). The upstream production applications include allocation, multiphase flow meter and virtual flow meter configuration, and assurance of PVT properties derived from surface samples.

Dr. Robbie Lansangan

Dr. Robbie Lansangan is a recognized industry expert in production measurement and allocation, sharing his knowledge in industry standards development under the American Petroleum Institute (API) and International Organization for Standardization (ISO) banners. His foundational training in Chem. Eng., understanding of metering technologies and product development, and a keen sense of the oil and gas business has made him an extremely valuable asset in the role of Measurement Engineering Technical Authority for a major oil company. From his early years as postdoctoral fellow engaged in research in enhanced oil recovery, to the delivery lead role for multiphase metering and subsea pumping for a major capital project, culminating in an assurance role in measurement systems design for major projects, proved to be a wealth of broad-based industry experience that allows him to bring a unique perspective to the subject of upstream production measurement.

Robbie has published numerous peer-reviewed articles and has given lectures and presentations in local and international settings. He received the BP Upstream Technology Award in 2013 for commercialization and a co-author of several patents on multiphase metering technologies. Robbie holds a Ph.D. degree in Chem. Eng. from the University of Tulsa. He also received post-graduate certifications from The University of Manchester (UK) in Engineering Management and Project Leadership, Management and Communications from George Washington University School of Business. His hobbies include indoor rock climbing, long range target shooting and culinary activities.
