Abstract
A method of removing dope from a tubing system in a wellbore includes the step of, prior to setting a production packer, reverse circulating fluid within a tubing-casing annulus (TCA) so that is flows from the tubing-casing annulus into a first tubing and propels at least one wiper plug within the first tubing in an uphole direction, thereby wiping the inside of the first tubing and removing excess dope.
