An administrator overseeing compensation payouts for people and businesses affected by the BP 2010 Macondo oil spill in the Gulf of Mexico said more than $5billio had already been issued.
A total of 62,162 claimants have been paid $5.037 billion.
The payments come after a settlement in 2012 tied to the explosion of the Deepwater Horizon drilling rig.
The disaster killed 11 workers and also caused the largest US offshore oil spill.
Oil major BP previously said it expected to pay $7.8billion to resolve claims under the settlement, however by February this had increased to $9.9billion.
BP shareholders have been urged today to reject chief executive Bob Dudley’s $15.3million pay package at the annual general meeting, which is currently taking place.
Mr Dudley’s remuneration was 5% up on the previous year while the group’s annual replacement cost profit slumped by 66%.
Shareholder advisory group PIRC described the package as “excessive” and advised investors attending the meeting in east London to vote against it.
Mr Dudley’s basic salary rose 3% to $1.8 million (£1.2 million) but his annual cash bonus was 57% lower at $1 million (£680,000).
