"BP Plc filed a lawsuit for more than $42 billion against Halliburton, which cemented the blown-out well which caused the Gulf of Mexico oil spill, after claiming a similar sum from rig owner Transocean.
Analysts said BP had little chance of winning the cases and was more likely trying to force the companies to settle. Management experts said pursuing the lawsuits could further damage BP's already battered reputation as well as reveal yet more embarrassing details of the way the disaster was handled."
