Method for enhancing the operational life of production parts in the oil and gas industry

A method for improving the operational life of a production part for use in underground oil recovery or production comprising:

• coating the production part with a layer of epoxy/phenolic to reduce a loss rate of the production part by improving corrosion resistance and mitigate pitting.

A method for improving the operational life of a production part for use in underground oil recovery or production comprising:

• coupling the production part(s) with a sacrificial anode to reduce a loss rate of the steel production parts by improving corrosion resistance and mitigate pitting.

12, A corrosion resistant production part comprising:

• a production part;
• and
• a layer of corrosion resistant alloy to reduce a loss rate of the steel production part by improving corrosion resistance and mitigate pitting.

The corrosion resistant production part of claim 12, wherein the corrosion resistant alloy is a nickel based alloy.

The corrosion resistant production part of claim 12, wherein the corrosion resistant alloy is stainless steel.

The corrosion resistant production part of claim 12, wherein the production part includes any one or more of:

• a steel sucker rod, couplings, pump parts, and tubes.

A corrosion resistant production part comprising:,

• a production part;
• and
• a corrosion resistant nickel based alloy coating.

A production part assembly having a corrosion resistant coating, the production part assembly comprising:

• a production part;
• and
• a built-up corrosion resistant alloy layer adhering to the production part, the corrosion resistant alloy layer having been deposited onto the production party by first spraying a first quantity of powdered alloy particle onto a prepared production part using a jet of gas, the gas being at a temperature below the fusing temperature of the metal particles, and the jet of gas having a velocity sufficient to cause the alloy particles to merge with one another upon impact with the production part and with one another so as to form an initial continuous alloy coating adhering to the surface of the production part, and then applying successive quantities of alloy particles over the initial continuous alloy coating using the jet of gas so as to form a coating incorporating the initial continuous alloy as its base and having an overall thickness that is a predetermined thickness.
