REMOVABLE DOWNHOLE ARTICLE WITH FRANGIBLE PROTECTIVE COATING, METHOD OF MAKING, AND METHOD OF USING THE SAME

A method of opening an orifice in a downhole article includes forming a downhole article having an orifice, the orifice having a selectively removable plug sealingly disposed therein, the selectively removable plug comprising a selectively removable plug body formed of a plug body material and a selectively removable sealant coating formed of a coating material disposed on an outer surface of the plug body. The method also includes disposing the article within a wellbore. The method further includes exposing the selectively removable plug to a first wellbore fluid that is configured to selectively remove the sealant coating and provide a fluid access to the plug body. The method further includes exposing the selectively removable plug body to a second wellbore fluid through the fluid access that is configured to selectively remove the plug body and using the second wellbore fluid to break the sealant coating into a plurality of pieces.
