Methods of conducting coiled tubing operations

A method of conducting a coiled tubing operation, comprising:

• applying a friction-reducing coating onto a surface of a metal substrate through use of a carrier fluid pumped onto the metal substrate in a liquid phase, wherein a carrier fluid to coating ratio is within a ratio of X:Y by weight wherein the value X is within a range of 5 to 8 and the value Y is within a second range of 2 to 5 and wherein the carrier fluid is of at least one of toluene, glycol, butyl acetate, t-butyl acetate and ethylene glycol;
• curing the friction-reducing coating onto the surface of the metal substrate to form a layer of the friction-reducing coating in contact with the surface of the metal substrate, wherein a surface energy of the layer of the friction-reducing coating is lesser than a surface energy of the surface of the metal substrate wherein the friction-reducing coating is composed of a single layer of silicon dioxide, aluminum oxide, and titanium dioxide;
• forming a tubing string from the metal substrate such that the surface of the metal substrate forms an inner surface of the tubing string, the tubing string having a central annulus, the inner surface, and an outer surface;
• and
• coiling the tubing string onto a spool.
