Abstract:
A tool assembly and method for completing a well are provided. The tool includes debris relief features that enable use in solids-laden environments, for example in the presence of sand. Forward and reverse circulation pathways to the isolated interval are present to allow clearing of debris from the wellbore annulus while the sealing device remains set against the wellbore.
