Abstract
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 method for increasing a service life of an oilfield operational component positioned to be used in an oilfield operation, the method comprising:
- at least partially coating an oilfield operational component positioned to be used in an oilfield operation to obtain a first coating layer on the oilfield operational component to enhance wear resistance of the oilfield operational component, such that the oilfield operational component exhibits a comparison factor indicative of an increased resistance to wear greater than about 2, the comparison factor being indicative of a first amount of time during which a portion of the coating wears to a first depth divided by a second amount of time during which a portion of the oilfield operation component without the coating wears to a second depth equal to the first depth;
- incorporating the oilfield operational component into an oilfield operation;
- exposing the oilfield operational component to fluid flow in the oilfield operation for a first period of time, the first period of time ranging from about 500 hours to about 2000 hours;
- at least partially removing at least a portion of the first coating layer from the oilfield operational component;
- and
- at least partially coating the oilfield operational component to obtain a second coating layer on the oilfield operational component, one or more of the first coating layer or the second coating layer comprising trifunctional silane, silanol fluid, and filler,
- the one or more of the first coating layer or the second coating layer being positioned to reduce a wear-rate of the oilfield operational component as exposed to fluid flow associated with the oilfield operation.

- exposing the oilfield operational component to fluid flow in the oilfield operation for a second period of time after at least partially coating the oilfield operational component to obtain the second coating layer on the oilfield operational component;
- and one or more of:
- the second period of time ranging from about 500 hours to about 2000 hours;
- or
- a ratio of the first period of time to the second period of time ranging from about 1.0 to about 1.5.
