“…The outcome of these tests is the solubilization ratio curves, interfacial tension, microemulsion viscosity, and ternary diagrams for different blends of surfactants and cosolvents depending on the difficulties of the oil and brine compositions, and temperature (Dean et al, 2022; Delshad, 1986; Flaaten et al, 2009; Fortenberry et al, 2013; Lake et al, 2014; Levitt et al, 2009; Satoh, 1984; Zhao et al, 2008). These data are used to model the microemulsion behavior in dynamic coreflood tests and field projects (Anderson et al, 2006; Dwarakanath et al, 2008; Flaaten et al, 2009; Hirasaki et al, 1997; Veedu et al, 2010, 2015).…”

Modeling the complex phase behavior of microemulsions has been the subject of research for decades for hydrocarbon oil and organic contaminant recoveries. The empirical Hand model has been the standard scheme for calculating phase behavior in reservoir simulators. On the other hand, the hydrophilic–lipophilic deviation (HLD) model in conjunction with the net curvature and average curvature models (HLD‐NAC) has provided some theoretical basis for modeling microemulsions. While the HLD‐NAC has been successful in describing salinity scans, only recently an HLD‐NAC approach was devised that could represent binodal curves with physical behavior, resulting in a succession of new microemulsion flash algorithms. While these new algorithms claimed to include the effects of cosolvent, there are only few works in the literature, which give an in‐depth description of the cosolvent modeling. Furthermore, to the best of our knowledge, no work has investigated the capability of HLD‐NAC models for predicting data for different cosolvent concentrations nor did any work present a comprehensive study of the application of HLD‐NAC against Hand model for formulations including cosolvents. This paper aims to contribute in filling such gap. We modify different versions of the new HLD‐NAC approach with physical binodal curves by providing more flexibility into controlling the binodal heights with the cosolvent concentration and investigate how well they can calibrate and predict data. Experimental data sets were considered here. The results suggest that some of the HLD‐NAC approaches produced negative solubilization ratios and the Hand model gave better predictions of the ternary diagram for extreme salinity values.

“…However, if system is simulated in the optimum salinity, consequently, good recovery can be observed. On the other hand, finer grid blocks have larger simulation time which is not feasible especially in the field scale optimization [4]. Yuan et al [5] truly stated that water flooding is more sensitive than polymer flooding to the coarse grid blocks.…”

In the current work, three scenarios were considered including water, polymer, and surfactant/polymer flooding for a heterogeneous sandstone reservoir in the Asmari Field located at the South West of Iran in a simulation work. No injection of chemical flooding has been done on this typical reservoir. Most of Enhanced Oil Recovery methods were considered to be water and gas injection in this reservoir so far. UTCHEM was used as a 3D, and compositional simulator to model of chemical flooding process. Sensitivity analyses of vital parameters have been carried out and the results of simulation work were presented.
