A drilling rig was transported to the Montara platform to drill a relief well to intercept the leaking well. The leak came to an end by pumping heavy mud into the well and wellbore, alleviating pressure to stop the oil flow and cementing – ‘capping’ the leak (WIKI).
PTTEPAA had four unsuccessful attempts in plugging the leak but prevailed on the fifth. The operation was difficult and challenging as the relief well needed to intercept a small pipe 2600m below the seabed. Approximately 3400 barrels of the mud were pumped into the relief well to plug the leak. When the interception was made- as the initial attempt of pumping mud down the well was occurring the fir broke out on the well platform, causing further delays to the operation.
