The composition of the completion fluid for deep wells and ultraprofundos in environments containing CO2

摘要

The composition of the completion fluid for deep wells and ultraprofundos in environments containing Co ~ 2 ~ the present invention describes a composition of a completion fluid which comprises glycerol of biodiesel to be used in deep wells and ultraprofundos in environments containing C The ~ 2 ~.This fluid shows mass specifies at least 1.15 g / cm3, viscosity suitable for pumping less than 2000 CP and corrosive potential of up to 3 mm in 30 years. In addition, the composition of completion fluid is compatible with elastomers normally employed and not degrade when exposed to temperatures lower than 100 198 C.
