Title: Time Discretization schemes in chemical flooding reservoir simulation
Abstract: The injection of chemicals such as polymer, surfactant(s), and alkali into oil reservoirs are referred to as chemical enhanced oil recovery (CEOR) and can significantly increase the oil recovery. Despite of the strong appeal that these techniques offer, the injection of chemicals is expensive and proper field optimization is required to ensure a robust recovery design, which can be obtained with several numerical simulation. Most attempts to develop physic-based reservoir simulator for chemical flooding are frustrated due to the particular physiochemistry of these methods. Therefore, most simulators reported in the literature use the IMPEC (implicit pressure, explicit concentrations) approach, which suffers from time-step restrictions, or fully implicit approaches that do cover the whole range of the microemulsion (ME) phase behavior. Implicit approaches for the surfactant-polymer flood considering all important phase behavior types and dependency on salinity, assuming no gas is present and slightly compressible brine, oil, and surfactant are presented and the effect of different modeling on the simulation performance is investigated and discussed.
Bio: Bruno R. B. Fernandes is a Postdoctoral fellow on the Center for Subsurface Energy and the Environment of the University of Texas at Austin. He received a B.S. in chemical engineering from the Federal University of Ceara, Brazil in 2011. He received a M.S. in chemical engineering from the same university in 2014. He received a PhD in Petroleum Engineering from the University of Texas at Austin in 2019. He is author or co-author of over 27 publications. His interests are on numerical methods applied to reservoir engineering problems, especially those involving time discretization, gridding and spatial discretization techniques.
