Abstract

Corrosion and/or calcium scale deposition on a surface in contact with corrosion forming components and/or scale forming components within a subterranean formation may be decreased, prevented, and/or inhibited by contacting the surface with at least one protein. The protein(s) may be or include, but is not limited to, at least one aspein protein, at least one aspolin protein, at least one dentine protein, at least one DRICH-1 protein, at least one nacrein protein, at least one SMDT-1 protein, derivatives thereof, fragments thereof, mimetics thereof, and combinations thereof. The surface may be or include, but is not limited to a metal surface, a plastic surface, a ceramic surface, a painted surface, a coated surface, and combinations thereof.

Claims (12)

1. A method comprising circulating an additive composition into a location selected from the group consisting of a subterranean reservoir wellbore, a refinery feed, and combinations thereof;

wherein circulating the additive composition occurs before, during, or after circulating a base fluid;

wherein the base fluid is selected from the group consisting of a drilling fluid, a completion fluid, a production fluid, a servicing fluid, an injection fluid, a refinery fluid, and combinations thereof;

wherein the additive composition comprises at least one protein selected from the group consisting of at least one aspein protein, at least one aspolin protein, at least one dentine protein, at least one DRICH-1 protein, at least one nacrein protein, at least one SMDT-1 protein, derivatives thereof, fragments thereof, mimetics thereof, and combinations thereof;

wherein the location comprises a fluid composition comprising the base fluid, the additive composition, and at least one foulant forming component, wherein the at least one foulant forming component comprises at least one member selected from the group consisting of metal carbonates, metal sulfates, metal oxides, metal phosphates, and combinations thereof; and

wherein the additive decreases foulant deposition.

2. The method of claim 1 , wherein the at least one aspein protein comprises an amino acid sequence that is at least 75% homologous to the amino acid sequence of SEQ ID NO:1; wherein the at least one aspolin protein comprises an amino acid sequence that is at least 75% homologous to the amino acid SEQ ID:2, the amino acid SEQ ID:3, and mimetics thereof; and combinations thereof.

3. The method of claim 1 , wherein an amount of the at least one protein within the additive composition ranges from about 0.01 wt % to about 10 wt % as compared to the total base fluid.

4. The method of claim 1 , further comprising at least one additional component selected from the group consisting of a scale inhibitor, a corrosion inhibitor, a surfactant, a biocide, a demulsifier, and combinations thereof.

5. The method of claim 4 , wherein the at least one scale inhibitor is selected from the group consisting of polyacrylates, polymaleates, hydroxypropylacrylates, phosphonates, soy protein polymers, polysaccharide based inhibitors, polyaspartic acid based inhibitors, and combinations thereof.

6. The method of claim 1 , wherein the at least one protein comprises at least one modification selected from the group consisting of a linker, a label, a tag, and combinations thereof.

7. The method of claim 1 where less foulant formation occurs in the presence of the at least one protein as compared to an otherwise identical fluid composition absent the at least one protein.
