Light intervention vessel perforates North Sea wells
The light well-intervention vessel CSO Seawell re-entered and reperforated two active subsea water-injection wells in Statoil's Heidrun field, offshore Norway. Coflexip Stena Offshore Norge AS, operator of the vessel, says one of the wells re-entered at Heidrun was in 340-m water, which is 150 m greater than the previous record for such an intervention.
