... present in traditional WI where the injected water short-cuts from injection to production wells leaving regions of oil saturated rock unrecovered (Needham and Doe, 1987). In addition to the injection of water-soluble polymer the injection of surfactants has been recognised since the 1970s (Healy...

.... The experimental temperatures were 50°C, 60°C and 70°C respectively. Some important factors such as water volume fraction, mixture velocity, temperature and surfactant, were analyzed how to affect the pressure drop characteristics. The large difference between the viscosities measured by a viscosity meter...

... ABSTRACT The conventional treatment process cannot meet the need for treatment of produced water from alkaline/surfactant/polymer flooding(ASP produced water) in Daqing oilfield. In this study, a new type of hydrophilic fibre ball medium was developed through surface modification method...

.... Moreover, injecting citric acid and SDS solution, anionic surfactant, and the reversal of the electrode were carried out in order to remove accumulated heavy metal in the cathode region. The following conclusions are obtained from this study. In the treatment of the electrokinetic, the removal effect...

... ABSTRACT A study was conducted to evaluate the removal of polycyclic aromatic hydrocarbon (in this case Naphthalene) from sand and a kaolinite/sand mix using an anionic surfactant, sodium dodecylsulfate (SDS). Results indicated that the adsorptive capacity of the kaolinite dominated...

... a simplified model problem which consists of pair vortices under the free surface as a flow driver and a thin surfactant layer is examined numerically the flow field is solved by using a standard finite difference scheme and the interface is traced by a front tracking method. The surfactant is assumed...
