Abstract
This invention relates generally to articles, devices, and methods for gas hydrate mitigation in deep-sea drilling applications. In certain embodiments, hydrate-phobic surfaces are provided that ensure passive enhancement of flow assurance and prevention of catastrophic failures in deep-sea oil and gas operations.
Claims15
An article for use in a deep sea oil and/or gas recovery operation, the article comprising a surface having receding contact angle of water, θrec of no less than 100°, wherein the article is a fuel gas line or instrument gas line and wherein the surface is a hydrate-phobic surface that inhibits hydrate adhesion thereupon in the presence of oil and/or gas.
An article for use in a deep sea oil and/or gas recovery operation, the article having a surface comprising fluorodecyl polyhedral oligomeric silsesquioxane, the surface having receding contact angle of water, θrec of no less than 100°, wherein the article is a fuel gas line or instrument gas line and wherein the surface is a hydrate-phobic surface that inhibits hydrate adhesion thereupon in the presence of oil and/or gas.
