BP Begins Drilling Relief Well at Gulf Oil Spill
- The company began work on the well early Sunday afternoon, but only announced that work had been begun Tuesday morning. The relief well also in 5,000 feet of water beneath the Gulf of Mexico, is planned to intercept the existing well around 13,000 feet below the seabed and permanently seal it.
A relief well is designed to intersect an existing well bore and pump heavy fluids and cement in to stop the leaking oil. BP has described it as the only way to definitively plug the oil leak.
