Abstract
A downhole tool has at least one diverter valve. The at least one diverter valve is 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 the gravel pack operation makes its way up the wellbore.
