Lignin from paper waste in interefacial tension (IFT) reduction for oil displacement

This study focusses on lignin potential in reducing interfacial tension (IFT) where primary and secondary recovery only recovers minimal amount of oil in most cases and leaving behind substantial amount of oil in place unrecovered. Commercial surfactant flooding had been used to address this issue w...

description This study focusses on lignin potential in reducing interfacial tension (IFT) where primary and secondary recovery only recovers minimal amount of oil in most cases and leaving behind substantial amount of oil in place unrecovered. Commercial surfactant flooding had been used to address this issue which yielded promising result at the expense of more monetary investment.
