... Interfacial tension (IFT) between oil and brine plays a key role in determining the capillary forces in the porous medium. When studying Enhanced Oil Recovery (EOR) methods, it is of great relevance to characterize the IFT. In the case of Pre-Salt reservoirs, CO 2 and water alternated...

... to analyze rock-fluid interactions between synthetic brine, crude oil from a Pre-Salt field and rocks and minerals with similar characteristics to the Pre-Salt formations. We studied the effects of aging time on different solid substrates. We found that, even though unaged quartz showed greater interaction...

...Abstract Abstract Carbonate reservoirs are characterized by neutral or oil-wet surfaces and the injection of water as a secondary recovery method may result in low oil recovery factors. The injection of low salinity brines has shown to be a method that can lead to significant additional oil...

... In the recent past, IOR/EOR technologies have been modified to include the effects of salinity of injected brine on oil recovery. Water Alternating Gas (WAG) is one such tertiary oil recovery process in the field. It greatly improves the synergy of various individual mechanisms underlining EOR...

... Abstract One of the major costs in crude oil production is lifting fluids to the surface for processing. During the lifting process the produced fluid composed of brine and crude oil encounters high shears and pressure drops caused by flowing through electrical submersible pumps or other forms...
