| This presentation will show you why labeling is “old thinking” and how labeling generates discontinuities and simulation errors in compositional processes.
Current compositional simulators include compositional equation-of-state fluid models, but do not account for compositional effects on relative permeability, capillary pressure, and grid-block flux calculations. Relative permeability, for example, is still based on “old thinking” related to labeling of phases as “oil, gas, and water.” Labeling causes significant discontinuities that can result in inaccuracies and instability in simulations of compositional processes, such as those for enhanced oil recovery (EOR). Several example cases, including water-alternating-gas and surfactant flooding, are given using a new type of compositional simulator with all labels removed.
One component of the novel simulator is the development of an equation of state (EoS) for relative permeabilities that eliminates phase labeling.
The relative permeability model is physically based and captures complex hysteresis effects through saturation and phase connectivity as well as changing wettability, interfacial tension, and pore morphology.
Results show increased robustness, improved accuracy, faster computational times, and less instabilities when phase labeling is removed. |

The Distinguished Lecturer Program is one of SPE’s most popular programs. Each season 30 to 35 experts from the oil and gas industry are selected to share their knowledge on the latest technologies and trends with SPE members. Established in 1961 with just three lecturers, the esteemed program now sends Distinguished Lecturers to SPE sections three times a year to give a total of more than 550 lectures all over the world.
The purpose of the program is to provide SPE sections with outstanding speakers for section meetings, and to recognize the professional contributions of the selected Distinguished Lecturers. The program promotes SPE’s mission to collect, disseminate, and exchange technical knowledge. It is funded primarily by the SPE Foundation through member donations, as well as a contribution from Offshore Europe. SPE appreciates the companies that allow their professionals to serve as lecturers and the additional support from AIME. |
