摘要： A method of fracturing a formation surrounding a wellbore comprises 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;
(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) remotely opening the flow path in the portion of tubular corresponding to the selected zone;
(vi) remotely isolating the throughbore of the tubular by closing the throughbore isolation means in the portion of tubular corresponding to the selected zone; and
(vii) fracturing at least part of the formation surrounding the well.
