Abstract
A method of conducting a gravel pack operation comprising lowering a fluid control assembly into a wellbore and supplying a fluid mixture comprising gravel into an annulus between the fluid control assembly and the wellbore to form a gravel pack. A washout assembly surrounds a pre-determined length of the fluid control assembly to remove gravel pack from around the predetermined length. A tattle-tale sub provides an indication of the location of the washout assembly relative to the fluid control assembly. The placement of a cement or inflatable packer is controlled relative to the pre-determined length of the fluid control assembly.
