Coating compositions for coating an oilfield operational component, and related methods, may include in some aspects a coating composition having a trifunctional silane, a silanol, and a filler. The coating composition may be applied to a surface of the oilfield operational component that is configured to be exposed to a fluid. The coating composition may be applied to at least partially cover or coat the surface. The coating composition may be configured to chemically bond with a cured primer composition that includes an epoxy.

A corrosion inhibitor composition, which includes (i) a date palm leaves extract, (ii) a benzimidazole compound having at least one a carbamate group, (iii) a pyridine compound, (iv) a thiourea compound, (v) a cinnamaldehyde compound, (vi) a metal iodide, (vii) urotropin, and (viii) a base fluid containing an alcohol and an organic acid. A method of inhibiting corrosion of metal during acid cleaning is also disclosed, whereby the metal is treated with an acidic treatment fluid containing 1 to 5 wt. % of an acid, based on a total weight of the acidic treatment fluid, and 0.1 to 5 vol. % of the corrosion inhibitor composition, based on a total volume of the acidic treatment fluid.

A super concentrate additive solution is disclosed herein. A super concentrate additive solution can be added into a heat transfer fluid to improve corrosion protection performance and to extend the service life of a heat transfer system or the fluids therein. A method includes adding a super concentrate additive solution to a heat transfer fluid to form a super additive heat transfer fluid and adding the mixture to a heat transfer system. A super concentrate additive solution can also be used in flexible production of a high corrosion protection performance heat transfer fluid concentrate, pre-diluted heat transfer fluids, or ready-for-use heat transfer fluids.
