.... Carbonates (calcite and aragonite) minerals are the most common depositing minerals. However, the extent of scaling index of carbonates is controlled by the concentration of Ca, HCO 3 , and CO 3 in the water sample. The characterization results confirm the results of modeling part. The results of SEM/EDS...

... chromatography (HPLC) was used to measure surfactant concentrations for thermal stability and coreflood testing. The steam-soak tests did reveal that combining N-octyl-2-pyrrolidone (NOP) with a sulfonate surfactant, alkyldiphenylethersulfonate (ADPES), could substantially improve oil recovery. This was dispite...
