Abstract: A composition of a packer fluid including biodiesel glycerin which can be used in deep and ultra-deep wells in environments containing CO2 and a process of using the same. This fluid may have a specific mass of at least 1.15 g/cm3, adequate viscosity for pumping at less than 2,000 cP and corrosive potential of up to 3 mm in 30 years. In addition, the packer fluid is compatible with the elastomers normally employed and does not degrade when exposed to temperatures lower than 100° C. The packer fluid is injected into an oil well as part of a well packer process.
