description Excessive water production has become one of the major problems in the mature oilfield. To mitigate this issue, polymer-based gel technique of the chemical method is favoured compared to the mechanical method due to its various advantages such as wide application in reservoirs and adjustable chemical properties. Currently, polymer with the less environmental effect is highly preferred over conventional polymer. The performance of palm oil-based polyurethane as a water shutoff agent was studied. The monomer used to synthesize palm oil-based polyurethane is methylene diphenyl diisocyanate (MDI) and palm oil-based polyol. The functional groups of gel’s structure and its thermal stability were characterized via Fourier transform infrared spectroscopy (FTIR) and thermal gravimetric analysis (TGA). Its gelation behaviour in term of gelation time and gel strength were studied.
