A method of fracturing a formation surrounding a wellbore is provided. A completion string including a tubular is provided, including at least two portions, each portion comprising an annulus isolation means, a selective flow path between the interior and the exterior of the tubular and a throughbore isolation means. The tubular is run into the wellbore. One isolates an annulus between the exterior of the tubular and the wellbore to thereby create at least two isolated zones. One selects any zone to be fractured and remotely opens the flow path in the portion of tubular corresponding to the selected zone. Further, one remotely isolates the throughbore of the tubular by closing the throughbore isolation means in the portion of tubular corresponding to the selected zone and fractures at least part of the formation surrounding the wellbore.
