... under different pores and different SI times. Finally, an experimental core model is established based on the above experimental results. The results show that wettability alteration appears in the oil-wet the core sample. As the contact time increases, the contact angle decreases continuously...

... flooding in B oilfield was assessed by reservoir simulation. This work built a new simulation model and investigated five kinds of formation damage due to asphaltene precipitation, which are porosity loss, permeability impairment, wettability alteration, relative permeability and capillary pressure...

... We investigated the utility of a modified Washburn method, combining results of two sorption experiments, to study wettability alteration processes. The main objective in deploying this technique was to avoid the difficulty of direct contact angle measurements in surfactant solutions...

... SmartWater and alkali/surfactant assisted chemical flooding processes are gaining some attention for enhanced oil recovery in carbonate reservoirs. The wettability alteration toward water-wet conditions caused by electro-kinetic induced favorable surface charge alteration is one main mechanism...

... and wettability alteration to maintain the new acquired permeability in the acid injection phase. The skin factor trend is modeled during injection and clean up phases to assess matrix acidizing interaction with formation. This paper will be focusing on real-time skin trend monitoring model which takes wellhead...

... oil recovery when polymer flooding is over. In this study, a new method was proposed to increase oil production using gas flooding with wettability alteration to gas-wetness when polymer flooding has been completed. The rock wettability was altered from liquid- to gas-wetness during gas flooding...

This however invites the possibilities of induced and aggravated scale deposition if the formation water is rich in divalent cations (as in the case...

... the field of nanotechnology-based EOR, where nanoparticles are used to target various aspects of EOR processes. For instance nanoparticle-based EOR approaches have been developed to promote wettability alteration, viscosity reduction of oil, stabilization of foam or emulsions and interfacial tension...

... the residual oil saturation whereas the low salinity water boosts the production rate by increasing the oil relative permeability through wettability alteration towards more a water-wet state. The latter finding was supported by comparing our simulations with the two corefloods reported by Chandrasekhar...

... Abstract Low salinity water injection (LSWI) is gaining popularity as an improved oil recovery technique on account of being cost effective compared to other water based enhanced oil recovery methods such as chemical and steam flooding. In this paper, the wettability alteration option in our...
