ABSTRACT:
A downhole tool has at least one diverter valve. The diverter valves are used to reduce pressure in a wellbore caused by frictional resistance to fluid flow during a gravel pack operation. The increased pressure tends to be created as the beta wave of a gravel pack operation makes its way up the wellbore.
