Abstract
Stimulation operations can be conducted by isolating portions of a subterranean formation adjacent to a highly deviated well bore. The planned settled height of a sand plug in a well bore adjacent a first zone of the subterranean formation is determined. The first zone is then perforated using a hydrajetting tool which is oriented so as to form perforations below the planned settled height of the sand plug.
