Halliburton is accusing BP of lying about the Deepwater Horizon oil rig before the 2010 Gulf oil spill and lying about Halliburton afterward in a suit filed Friday in Texas court. The day before the disaster, BP allegedly gave Halliburton bad info about where gas and oil pockets were in the well so cement work wouldn't be stalled, Bloomberg's Margaret Cronin Fisk explains. After the spill, BP said Halliburton's cement job was "a root cause of the blowout." So Halliburton is suing for "negligent misrepresentation, business disparagement and defamation," Reuters reports.
