BP has handed the bill for clearing up the disastrous 2010 Deepwater Horizon oil spill to Halliburton, the US contractor it claims botched the cement work on the failed rig. The oil group has filed a suit in New Orleans seeking "the amount of costs and expenses incurred by BP to clean up and remediate the oil spill, the lost profits from and/or diminution in value of the Macondo prospect, and all other costs and damages incurred by BP related to the Deepwater Horizon incident and resulting oil spill", according to the filing.BP did not specify the amount of damages it is seeking from Halliburton, which provided cement contracting services on the well in the Gulf of Mexico. But it previously estimated the clean-up will cost $42bn (£27bn). The oil firm wants Halliburton to pay damages "equal to, or in the alternative proportional to Halliburton's fault," to cover clean-up costs and any government fines BP may face. A Halliburton spokeswoman said: "Halliburton stands firm that we are indemnified by BP against losses resulting from the Macondo incident."[also refers to Cameron Intl., Anadarko, Weatherford, Transocean]
