Pipe dope restricting fluid communication between a well bore and a subterranean formation is contacted with a liquid perhaloalkane having no more than three carbon atoms per molecule, such as 1,1,2-trichloro-1,2,2-trifluoroethane, to improve fluid communication. The halocarbon can also be contacted with pipe dope on tubulars to remove the pipe dope from the tubulars. |
