Oil spill cost up at $2.35-billion: BP

The cost of cleaning up the devastating Gulf of Mexico oil spill has gone up to $2.35 billion, less than a week after it was estimated at $2.1 billion, BP said today.

This included the cost of the spill response, containment, relief well drilling, grants to the Gulf states, claims paid and federal expenses, BP said.

Meanwhile, adding to the company's woes, the number of claims over the oil spill has gone up to a massive 74,000 from the earlier estimated 65,000.

On 21 June, the energy major had pegged the spill-related costs at $2 billion, up from $1.4 billion in the previous week.

"To date, almost 74,000 claims have been filed and more than 39,000 payments have been made, totalling almost $126 million," BP said in a statement.

Shares of BP plunged to a 14-year-low at 302.35 pence in early trade on the London Stock Exchange.
