Abstract
Improved darts and methods of using these darts in subterranean wells are disclosed. The improved dart (lOO)comprises a foam portion (102) and a rubber portion (104) coupled to the foam portion. A dart nose (106) is coupled to at least one of the foam portion and the rubber portion. The foam portion and the rubber portion are configured to interface with an inner surface of at least one of a well bore wall, a pipe, and a casing string.
