Abstract
Fouling caused by contaminants onto a metallic tubular, flow conduit or vessel in an underground reservoir or extending from or to an underground reservoir may be inhibited by applying onto the surface of the metallic tubular, flow conduit or vessel a treatment agent comprising a hydrophobic tail and an anchor. The anchor attaches the treatment agent onto the surface of the metallic tubular, flow conduit or vessel.

A method of inhibiting the deposition of contaminants onto a metallic tubular, flow conduit or vessel in a well or extending from or to a well, wherein the surface of the metallic tubular, flow conduit or vessel is treated with a primer to impart reactive functional groups onto the surface, the method comprising:
- (a) pumping into a well a fluid comprising a surface modifying treatment agent comprising an anchor and a hydrophobic tail, wherein the anchor binds to a reactive functional group on the surface of the metallic tubular, flow conduit or vessel;
- and
- (b) inhibiting the deposition of contaminants onto the metallic well tubular surface by exposing the hydrophobic tail of the surface modifying treatment agent to fluids containing the contaminants.
A method of inhibiting the deposition of contaminants onto a metallic tubular, flow conduit or vessel in a well or extending from or to a well, the method comprising:
- (a) applying a primer onto at least a portion of the metallic tubular, flow conduit or vessel and forming a coating from the primer on at least a portion of the surface of the metallic tubular, flow conduit or vessel;
- (b) applying onto the coating a surface modifying treatment agent having an anchor and a hydrophobic tail wherein a reactive site for the anchor is on the coating;
- (c) attaching the anchor of the surface modifying treatment agent onto at least a portion of the reactive site;
- and
- (d) inhibiting the deposition of contaminants from a fluid onto the metallic tubular, flow conduit or vessel by exposing the fluid to the hydrophobic tail.
