| Popis: | To address harsh brine issues of mature fields, extended surfactants with outstanding hardness tolerance were selected in this research. The involved surfactant and site crude oil were characterized against the hydrophilic-lipophilic deviation (HLD) theory (i.e., K, Cc and EACN values of the system). A surfactant-only formulation was successfully developed with a predictive tool of the HLD theory based on the microemulsion phase behaviors. The developed surfactant slug can be easily prepared in harsh formation brine of 161,860 mg/L total dissolved solids (TDS) without any water pre-treatment with fast coalescence rate ( |
