BP are suing Halliburton for damages arising from the Deepwater oil spill in the Gulf of Mexico that resulted in the deaths of 11 oil workers and a massive spillage in the gulf of Mexico, the worst ever in US history.

Halliburton produced the cement cap that was designed to seal the well in the event of an emergency and it failed to do so when the initial safety mechanism to prevent blow outs collapsed.

The spillage has cost BP £9 billion in clean up costs and compensation that will probably end up more than double this sum and the Halliburton action is one of a number as BP looks to share the blame and financial loss.
