Claim Text:
1. A method of fracturing a formation surrounding a wellbore comprising the steps of: (i) providing a tubular 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 for selectively obturating a throughbore of the tubular; (ii) running the tubular into the wellbore; (iii) isolating an annulus between the exterior of the tubular and the wellbore to thereby create at least two isolated zones; (iv) selecting any zone to be fractured; (v) opening, such as remotely opening, the flow path in the portion of tubular corresponding to the selected zone so as to allow fluid to flow between the interior and the exterior of the tubular; (vi) isolating, such as remotely isolating, the throughbore of the tubular so as to obturate the throughbore by closing the throughbore isolation means in the portion of tubular corresponding to the selected zone so as to prevent fluid from flowing along the throughbore; and (vii) fracturing at least part of the formation surrounding the well.
