LA DEFENSE (dpa-AFX) - Total SA (TOT, TTFNF.PK, TTA.L) announced that a well intervention operation has stopped the G4 well leak on the Elgin complex, 240km from Aberdeen in the UK North Sea.
The well intervention operation, which involved pumping heavy mud into the leaking well, began on May 15 and the leak was stopped 12 hours later. The G4 well had been leaking following an incident on March 25, which led to 238 people being quickly and safely evacuated from Elgin and an adjacent drilling rig, the Rowan Viking.
From an estimated initial gas flow rate of around 2 kg/second, the leak had progressively decreased to an estimated 0.5 kg/s.
Since the beginning of the incident, experts from Total and specialist contractors have been working to stop the leak. During the coming days, these teams will closely monitor the G4 well in order to confirm the complete success of the intervention.
