Abstract
The present invention provides treated gravel pack screens comprising a metal surface and a hydrophobic surface layer applied thereto, directly or through an intermediate layer. The surface layer comprises a self-assembled monolayer prepared from a fluorinated material having the structure: wherein A is an oxygen radical or a chemical bond; n is 1 to 20; Y is H, F, CHor CF; X is H or F; b is at least 1, m is 0 to 50, p is 1 to 20, and Z is an acid group or an acid derivative. Also provided is a method of reducing deposition of a contaminant on a metal surface of a gravel pack screen, comprising: contacting the surface with the above fluorinated material in a diluent, directly or through an intermediate layer; forming a hydrophobic surface layer on the surface; and introducing a fluid through the gravel pack screen.
