BP has said the cost of dealing with its oil spill in the Gulf of Mexico had risen to eight billion dollars (6.23 billion euros) and it continues to spend around 70 million euros a day.
That estimate came as the oil giant concluded an internal investigation into the causes of the deadly disaster.
BP sources said the findings will likely be released next week
The investigation was led by BP’s head of safety and operations, Mark Bly.
BP said Bly acted in an “independent” capacity, seeking the truth, rather than aiming to bolster the company’s position in legal disputes with the US government and the others involved in the accident.
US politicians have already criticised the terms of the BP probe as being too narrow.
Some media reports citing leaks of parts of the report say lower level employees will be blamed for making mistakes that contributed to the blast.
This could be seen as an attempt by BP to deflect criticism of top management and company culture — something BP was accused of doing after a blast at its Texas City refinery in 2005, which killed 15 workers.
