..., while others function as crystal modifiers. 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...

Paper Number: OTC-29868-MS
... 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...
