Реферат: A method of sealing an annulus around a drill-pipe when drilling down-hole comprises: providing a deflated packer on a drill-pipe when drilling down-hole; opening one or more ports to the packer using a ball-activated valve; and circulating drilling fluid to inflate said packer through said one or more ports, to thereby form a seal in the annulus around the drill-pipe. An apparatus to carry out this method is also provided.
