Abstract

An unbalanced sub-assembly includes a turbine and a shaft coupled to the turbine at a first end of the shaft. The unbalanced sub-assembly is capable of rotating and imparting a vibration to the casing in response to a fluid being passed through the casing. A rupture disc is positioned on one end of the unbalanced sub assembly. The rupture disc is configured to rupture above a specified differential pressure threshold caused by fluid flowing through the vibration assembly. The rupture disc is capable of allowing the fluid to bypass the unbalanced sub assembly when the rupture disc is in a ruptured state. The rupture disc directs fluid through the unbalanced sub assembly when the rupture disc is in an un-ruptured state.
