The use of polymeric materials to manage sand production has been widely used in the field of production of the petroleum industry. One of the polymers being developed is <br /> <br /> <br /> <br /> <br /> polyurethane synthesized from castor oil as an alternative polymer in controlling sand production in the oil reservoir. Polyurethane was prepared by polymerization of ricinoleic acid obtained from hydrolysis of castor oil and diisocyanate monomer, MDI, with the mole ratio of 1:1. The modified polyurethanes were made by adding of 0.075 mol PEG 400 and 0.5 mol glycerol, respectively, after polymerization. Polyurethanes were applied to the <br /> <br /> <br /> <br /> <br /> artificial core containing 75% cement and 25% sand with submersion and vacuum immersion methods at various concentration 1-6% (w/v) and drying temperature of artificial core 80 and 100oC. The results in this research were characterized by analysis of hydroxylnumber, <br /> <br /> <br /> <br /> <br /> analysis of functional group by FTIR (Fourier Transform Infrared Spectroscopy), viscosity by viscometer, and surface analysis by SEM (Scanning Electron Microscopy). <br /> <br /> <br /> <br /> <br /> Optimization of polyurethanes on the artificial core observed in the measurement of physical and mechanical properties of rocks were porosity, permeability, and compressive strength. Based on the results obtained, the optimal concentration of polyurethane used in the <br /> <br /> <br /> <br /> <br /> immersion of the artificial core was 5.5%, which resulted in the increase compressive strength about 150-250 psi, the reduce porosity about 2-2.6% and the reduce permeability <br /> <br /> <br /> <br /> <br /> about 3-13 md. The effect of PEG and glycerol in the modification of polyurethanes resulted in the increase compressive strength 190-880 psi, the reduce porosity about 5-6.5% and the reduce permeability about 4-9 md. In addition, the intrinsic viscosity of the polyurethane was <br /> <br /> <br /> <br /> <br /> 0.729 dL/g and increased to 1.350 and 2.677 dL/g with the addition of PEG and glycerol, respectively. Based on the results of modification and optimization of polyurethanes, they can increase the degree of consolidation of the rock, so polyurethanes can be used as an alternative polymer to resolve the problem of the presence of sand in the oil reservoir.
