The adsorption behaviour of aqueous solutions of anionic surfactant and polymeric surfactant derived from Jatropha oil onto sand surface was investigated in connection of their application in enhanced oil recovery. The loss of surfactant by adsorption on reservoir rock must be premeditated for proper design of injected surfactant slugs in a chemical enhanced oil recovery. The sand particles used in the present study as representative of reservoir rock were characterized by Fourier transform infrared and energy-dispersive X-ray analyses.Adsorption properties were studied as a function of time and concentration for both surfactant and polymeric surfactant. The equilibrium adsorption data were fitted with the Langmuir, Freundlich, Temkin, and Redlich-Peterson isotherm models. Thermodynamic studies revealed that the adsorption of surfactant and polymeric surfactant were spontaneous in sand-aqueous system. The kinetics of adsorption was explained using different equations, namely, the Lagergren first-order equation, the pseudo second-order equation, and the intraparticle diffusion equation. The kinetic parameters in each model were identified and measured in order to explain adsorption dynamics.

Ionic liquids (IL) have emerged as a prospective new material for a wide range of industrial applications, owing to their unique structures and properties. Hence, understanding the structure–property relationships of IL is very important for both fundamental and industrial applications. In this study, a series of imidazolium‐based IL with different chain lengths, namely C8mimBF4, C10mimBF4 and C12mimBF4, were synthesized. Their molecular structures were confirmed by proton nuclear magnetic resonance (1H NMR) and Fourier transform infrared (FTIR) analysis. Thermal gravimetric analysis (TGA) revealed that the IL synthesized were thermally stable in the desired temperature range. Dynamic light scattering (DLS) results of IL was analyzed in order to understand the effect of alkyl length on micellar size. Conductivity and surface tension measurements were carried out to determine the adsorption and aggregation characteristics in aqueous solutions. The influences of temperature as well as alkyl chain length on viscosity were also investigated. Surface adsorption parameters such as surface excess, minimum area, effectiveness and efficiency were also determined from equilibrium surface tension data. A careful analysis of the thermodynamic aspects of air‐ionic liquid aqueous systems reveals that free energies of adsorption are favoured over micellization for all systems.

Hybrid CO₂ EOR using polymer‐assisted carbonated low salinity waterflood to improve CO₂ deliverability and mobility

A hybrid polymer‐assisted carbonated low‐salinity waterflood (PCLSWF) is a low‐salinity waterflood‐based enhanced oil recovery (EOR) co‐injecting CO2 and polymer. In the hybrid process, the low salinity of make‐up brine enhances CO2 deliverability into a reservoir due to the salting‐out phenomenon. This PCLSWF introduces the following synergetic effects: 1) wettability modification; 2) decreasing oil viscosity; 3) increasing brine viscosity. These effects are evaluated in core‐ and pilot‐scaled systems. First, the PCLSWF induces ion‐exchange of Ca2+ and improves wettability following MIE (multi‐components ionic exchange) theory. The wettability modification effect is enhanced in the pilot‐scaled system because the low pH of the PLCSWF dissolves more cemented calcite mineral producing Ca2+ and resulting in more ion‐exchange of Ca2+. Secondly, a lot of dissolved CO2 in brine is transferred into oil, consequently decreasing the viscosity and density of oil. Finally, polymer injection increases the viscosity of the displacing fluid. Although it undergoes mechanical and chemical degradation, it still improves mobility ratio and sweep efficiency. In the pilot‐scaled system, the PCLSWF enhances oil recovery up to 12%, 6%, and 2% over the low salinity waterflood (LSWF), low salinity polymer flood (LSPF), and carbonated low salinity waterflood (CLSWF) respectively. The optimization process maximizes the efficiency of the PCLSWF, and it is recommended that tertiary PCLSWF is deployed following the secondary CLSWF. The optimized injection design of the PCLSWF increases the net present value up to 18% more than the LSWF. © 2017 Society of Chemical Industry and John Wiley & Sons, Ltd.
