In order to investigate this, several experiments for precipitating Calcium Sulfate were carried out in the laboratory by mixing Calcium, and Sulfate brines. Following the precipitation process, the solid was filtered out using vacuum filtration. Subsequently...

... 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 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 recoveries...
