Abstract
A method of completing a wellbore in a hydrocarbon-containing subterranean formation includes injecting a completion fluid into the wellbore to form a hydrostatic gradient at a hydrocarbon-producing depth in the wellbore. The completion fluid is an aqueous solution including 10 to 20 w/v % of a dicationic surfactant of Formula (I) having an alkyl linker and a lipophilic tail. The completion fluid reduces a torque of the wellbore by at least 25% at a temperature of at least 150° F.
