ABSTRACT:
Zonal isolation of well bores is often desirable for performing downhole operations such as stimulation operations. In certain embodiments, diverter plugs for achieving zonal isolation in a casing string in a well bore may comprise a mandrel having a first end and a second end; a compressible body attached to and surrounding a longitudinal portion of the mandrel; and a sealing nose attached to the first end of the mandrel. In certain embodiments, systems for achieving zonal isolation of a casing string in a well bore may comprise a diverter plug comprising a mandrel having a first end and a second end, a compressible body attached to and surrounding a longitudinal portion of the mandrel, and a sealing nose attached to the first end of the mandrel; and a landing collar sized to mate with a portion of the sealing nose of the diverter plug. Associated methods are also provided.
