Evaluation of Selected Salts for Potential Application for Optimized Salinity Water Fooding in Niger Delta Crude Oil-Rock Systems: A Laboratory Approach.

This work has assessed the comparative performance of four salts (NaCl, K₂SO₄, CaCl₂, and MgSO₄) in the optimized salinity water flooding mode. This was done by carrying out core flooding tests using crude oil, brines and cores sourced from a Niger Delta field. Inter-facial Tension tests were also performed on each crude brine system to understand the specific role of fluid-fluid interaction. The results obtained from the study are quite interesting as additional recovery ranging from 5-26% were obtained in the secondary and tertiary mode. [ABSTRACT FROM AUTHOR]
