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.
Claims30
A method for preparing a coating composition for application to at least a portion of an oilfield operational component to reduce damage induced by flow of an oilfield fluid, the method comprising:
- providing trifunctional silane;
- providing silanol fluid;
- providing filler;
- combining the trifunctional silane, the silanol fluid, and the filler;
- providing titanium dioxide;
- and
- mixing one or more of the titanium dioxide, the trifunctional silane, the silanol fluid, or the filler to obtain the coating composition, the coating composition being configured to form a coating layer on the at least a portion of the component, the coating layer configured to reduce damage induced by flow of an oilfield fluid, such that the oilfield operational component exhibits a comparison factor indicative of an increased resistance to wear greater than about 2.
A method for adjusting a hardness of a coating configured to protect at least a portion of component configured to be exposed to an oilfield fluid, such that the component exhibits a comparison factor indicative of an increased resistance to wear greater than about 2, the method comprising:
- preparing a coating composition comprising:
- an amount of titanium dioxide;
- an amount of trifunctional silane;
- an amount of silanol fluid;
- and
- an amount of filler, one or more of the amount of titanium dioxide, the amount of trifunctional silane, the amount of silanol fluid, or the amount of filler being mixed to prepare the coating composition;
- and
- one or more of the following:
- increasing the amount of silanol fluid relative to at least one of the amount of trifunctional silane or the amount of filler to decrease the hardness of the coating;
- decreasing the amount of silanol fluid relative to at least one of the amount of trifunctional silane or the amount of filler to increase the hardness of the coating;
- increasing the amount of filler relative to at least one of the amount of trifunctional silane or the amount of silanol fluid to increase the hardness of the coating;
- or
- decreasing the amount of filler relative to at least one of the amount of trifunctional silane or the amount of silanol fluid to decrease the hardness of the coating,
- wherein the coating composition is configured to form a coating layer on the at least a portion of the component, the coating layer configured to reduce damage induced by flow of an oilfield fluid.
A method for adjusting a viscosity of a coating composition for application to at least a portion of an oilfield operational component configured to be exposed to an oilfield fluid, the method comprising:
- preparing a coating composition comprising:
- an amount of titanium dioxide;
- an amount of trifunctional silane;
- an amount of silanol fluid;
- an amount of filler;
- and
- an amount of solvent, one or more of the amount of titanium dioxide, the amount of trifunctional silane, the amount of silanol fluid, the amount of filler, or the amount of solvent being mixed to prepare the coating composition;
- and
- one of:
- increasing the amount of solvent relative to at least one of the amount of trifunctional silane, the amount of silanol fluid, or the amount of filler to reduce the viscosity of the coating composition;
- or
- decreasing the amount of solvent relative to at least one of the amount of trifunctional silane, the amount of silanol fluid, or the amount of filler to increase the viscosity of the coating composition, the coating composition being configured to form a coating layer on the at least a portion of the component, the coating layer configured to reduce damage induced by flow of an oilfield fluid, such that the oilfield operational component exhibits a comparison factor indicative of an increased resistance to wear greater than about 2.
A method for preparing a coating composition for application to at least a portion of a fracturing system component to reduce damage induced by flow of an oilfield fluid, the method comprising:
- providing trifunctional silane;
- providing silanol fluid;
- providing filler;
- combining the trifunctional silane, the silanol fluid, and the filler;
- and
- mixing one or more of the trifunctional silane, the silanol fluid, or the filler to obtain the coating composition, the coating composition being configured to form a coating layer on the at least a portion of the fracturing system component, the at least a portion of the fracturing system component including one or more of:
- (a) at least a portion of a goat head, which exhibits a comparison factor indicative of an increased resistance to wear ranging from about 5 to about 30;
- or
- (b) at least a portion of a frac iron component, which exhibits a comparison factor indicative of an increased resistance to wear ranging from about 2 to about 20.
