Abstract

This work has assessed the comparative performance of four salts (NaCl, K_2SO_4, CaCl_2, and MgSO_4) 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.
