The oil spill disaster in the Gulf of Mexico and then the series of events, that forced the British oil company to even change its CEO, has in money terms cost it more than $6 billion.

British Petroleum (BP) said that the total expense on the whole even was$6.1 billion. And this amount is expected to increase even more since the company expects to have to pay out massive compensation payouts.

The total expenditure includes spill response, relief well drilling, the "static kill" and cementing of the damaged well, grants to Gulf states, claims paid and federal costs.

It had announced last week that the hole has been finally closed and cemented. The oil well was opened after an explosion took place on the Deepwater Horizon rig April 20 that killed 11 workers.

The good news is that the expenses are still way below of what the company had anticipated.

They were expecting the cost to be close to $32.2 billion and would have pushed it into a loss of $16.9 billion. This was the biggest quarterly loss that it had faced.
