... of the ethylene oxide (EO) groups in the hydrophilic head known as the cloud point temperature. This study aims to highlight the existence of temperature operating window for nonionic surfactants to optimize oil recovery during EOR applications in unconventional reservoirs. Two nonylphenol (NP) ethoxylated...

... good for wettability alteration and could recover 70-80% of OOIP during spontaneous imbibition. Secondary waterflooding with the wettability altering surfactant increased the oil recovery over the waterflooding without the surfactants (from 29% to 40% OOIP). calcite plate cloud point...

... to the formation, and their impact on shale hardness. Pressure propagation experiments have been performed under high pressure-high temperature conditions. For the silicate muds, an ability to reduce pressure propagation was verified; for others, including cloud point glycols which have been suggested to plug...

... no adjustable parameters for the solid-liquid equilibria. Model predictions are compared to binary solid-liquid, solid-vapor, and solid-liquid-vapor equilibria data with good results. Also, a high-pressure, cold-stage microscope technique was developed to measure cloud points of live oils with which to test...
