The Poisson-Boltzmann equation is a partial differential equation that describes the electrostatic potential in a system of charged particles, accounting for the effects of ionic concentration and the dielectric properties of the medium. It is widely used in physical chemistry and biophysics to model interactions in electrolyte solutions and biomolecular systems.

This study was conducted to investigate the phenomenon of oil removal from inside pores using a selfdesigned microfluidic test kit. An artificial micromodel chip as a representation of porous rocks has been created with a uniform pore... more
In recent years, controlling the salinity and composition of the injected water has become an emerging enhanced oil recovery (EOR) technique, often described as low salinity (LS) waterflooding. This work is done with the intention to... more
The long-held industry view that the Low Salinity Effect (LSE) depends mainly on rock-fluid 10 interactions has led to failures and successes that can be explained by fluid-fluid interactions. 11 Therefore, elevating our knowledge about... more

CO2 convective mixing in water has been visualized in Hele-Shaw and PVT cell experiments but not at the pore scale. Furthermore, CO2 convective mixing in a three-phase system (i.e., CO2 in the presence of both water and oil) has not been... more
The implementation of polymer injection on a field scale needs a preliminary laboratory test to analyze the performance and flow behavior of polymer injection in a porous media. Compared to coreflooding method, micromodel provides the... more
Direct pore-scale visualizations using micromodels for low salinity water injection (LSWI) have revealed that the contact between low salinity water and crude oil can provoke formation of water-in-oil micro-dispersions. This experimental... more
A preliminary enhanced oil recovery (EOR) screening was completed for the Ben Nevis Formation, Hebron Field, offshore Canada. Polymer flooding was determined to be the most viable methodology based on the oil and reservoir properties and... more
Low Salinity Waterflooding (LSW) is a promising technology for improving oil recovery in secondary and tertiary stages over the conventional waterflooding (HSW). As widely reported in the literature, this emerging recovery approach has... more
This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will... more
In situ mixing by dispersive transport of salt and viscous fingering between the injected low-salinity (LS) brine and high-salinity (HS) formation brine can jeopardize the performance of low-salinity waterflooding (LSWF). In our previous... more

In microfluidic studies of improved oil recovery, mostly pore networks with uniform depth and surface chemistry are used. To better mimic the multiple porosity length scales and surface heterogeneity of carbonate reservoirs, we coated a... more
Low salinity water (LSW) flooding is a commonly used technique to recover remaining oil. Efficiency of this method can be improved by decreasing salinity of the injected fluid during LSW flooding. However, the environment of low salinity... more
Low-salinity water (LSW) flooding is one of the newest EOR techniques which has more advantageous over other EOR techniques. This research employed a heterogeneous synthetic three-dimensional reservoir to model LSW flooding for a... more
In this report a mathematical model, which is based on the electrostatic potential and elastic/ mechanical properties, is presented for formation and stability prediction of DNA-dendrimer nanocluster. This model is built upon the... more
Iron minerals are hydrophobic minerals predominately found in sandstone formations with their role in wettability alteration not fully understood. With the reservoir rock being a complex system of multiple minerals, the control of... more
The results of many previous studies on low salinity/controlled ions water (CIW) flooding suggest that future laboratory and modeling investigations are required to comprehensively understand and interpret the achieved observations. In... more
After the publication of this article in 2018, we found that a similar set of methods to measure capillary pressure of paper membranes as a function of saturation was described by Buser 1 in a Ph.D. thesis in 2016. We request all... more
Wettability alteration is the principal low-salinity-effect (LSE) in many oil-brine-rock (OBR) systems. Our recent experimental results have demonstrated that wettability alteration by low salinity is slow. It is expected that the... more
The efficiency of low salinity waterflooding, particularly during tertiary mode injection, is highly controlled by in situ mixing between the stagnant regions holding high salinity water (HSW) and the flowing regions containing low... more
A DNA-dendronlzed polymor nano--cluster Is generally formed by wrapping the DNA aromd a dendronized polymer which has a cylindrical shape. The e1eclrostatic free energy in terms of different contribution of fixed and mobile charges and... more
