DIVERTER PLUGS FOR USE IN WELL BORES AND ASSOCIATED METHODS OF USE |
摘要 |
Zonal isolation of well bores is often desirable for performing downhole operations such as stimulation operations. In certain embodiments, diverter plugs (310) for achieving zonal isolation in a casing string (330) in a well bore may comprise a mandrel (313) having a first end and a second end; a compressible body (315) attached to and surrounding a longitudinal portion of the mandrel; and a sealing nose (317) 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 (323) sized to mate with a portion of the sealing nose of the diverter plug. Associated methods are also provided.
