Correlations for Oil Recovery Efficiency of a Niger Delta Well under Emulsion Flooding Operations: A core Sample Analysis

This study presents a core sample analysis of emulsion flooding for enhanced oil recovery in Niger Delta reservoirs using palm oil mill waste materials (oil palm mills effluent and palm bunch). The experiment investigates the effect of emulsion viscosity on oil recovery efficiency. Results show that increasing emulsion viscosity improves oil recovery, with the 40/60 emulsion ratio yielding the highest recovery efficiency of 55.2%. A predictive model was developed, and the predicted recovery efficiencies were in good agreement with experimental values with 95.2% accuracy.
