Abstract
A method for treating surfaces of equipment comprising applying a Self Assembled Monolayer of a moiety to at least one surface of the equipment, wherein the equipment is selected from the group consisting of level sensors, sucker rods, turbine meters, Coriolis meters, magnetic flow meters, down hole pumps, check valves, valves, cables, drill bits, wire lines, and pigs, and the moiety may be present in di or tri headed form or as a bis, gem-bis or tris headed form, and is a phosphonate, and equipment having at least one surface comprising such a treated surface.
Claims23
A system comprising
- a liquid environment that comprises at least one contaminant selected from the group consisting of paraffins and asphaltene;
- and,
- a surface residing within the environment comprising a Self Assembled Monolayer of a moiety, wherein the moiety comprises a di or tri headed or as a bis, gem-bis or tris headed form, and is phosphonate;
- wherein the monolayer resists deposition of paraffins or asphaltenes on the surface residing within the environment.
A system comprising
- a hydrocarbon environment;
- and,
- a surface residing within the environment comprising a Self Assembled Monolayer of a moiety, wherein the moiety comprises a di or tri headed or as a bis, gem-bis or tris headed form, and is phosphonate;
- wherein the monolayer is anti-paraffin.
A system comprising
- a hydrocarbon environment;
- and,
- a surface residing within the environment comprising a Self Assembled Monolayer of a moiety, wherein the moiety comprises a di or tri headed or as a bis, gem-bis or tris headed form, and is phosphonate;
- wherein the monolayer is resistant to an initial affixation of paraffin or asphaltene on the surface.
