Interfacial Tension Measurement on Sodium Hydroxide Solution as Alkaline Flooding for Light Oil from Thailand
Abstract:
Because of an increasing world-energy demand, water-flooding is not the practical technology to produce more oil due to the high interfacial tension or IFT. To achieve this, enhanced-oil-recovery (EOR) technique like alkaline-flooding becomes more significant. For alkaline-flooding by sodium hydroxide, in-situ surfactant is created between the alkaline solution and the organic acids in oil to reduce IFT thus making oil flow easily. Consequently, the objective of this research is to investigate the effects of alkaline concentration, brine salinity, temperature and pressure on oil production and to measure the IFT from rising drop method for oil in Thailand. The results show that IFT is reduced from 37 to 0.2 mN/m with the increases of temperature, alkaline concentration and brine salinity. However, pressure has less effect on IFT reduction. The results can be applied to use as pre-flooding approach to reduce IFT along with water-flooding for oil recovery with lower cost.
