Abstract:
A method for forming a coating upon a wellbore tool includes forming a pattern of features supported by a body and forming a coating over the pattern of features. Forming the pattern of features includes forming a first feature and forming a second feature spaced from the first feature by a first width at a first elevation and by a second width at a second elevation, the second width being different than the first width, and the first elevation being further from an interior region of the body than the second elevation. Also disclosed is a wellbore tool comprising a coating covering a pattern of features and a method of utilizing a wellbore tool in a subterranean formation, the method including forming a pattern of features, forming a coating over the pattern of features, and disposing the wellbore tool in a borehole.
