BP is facing charges of between $2 billion and $3 billion in the third quarter as a result of planned divestments, with the UK supermajor set to hit $10 billion of asset sales by the end of this year.

The London-based giant has also warned of a "significantly higher" underlying effective tax rate in its third-quarter result due to various factors - including the impact of Hurricane Barry in the US Gulf of Mexico - that have chopped 100,000 barrels of oil equivalent per day off its production.
