It said its replacement cost profits rose to USD 16.5 billion from the USD 4.7 billion for the same period last year, largely reflecting a one-off gain from the sale of its stake in TNK-BP.
The replacement cost figure omits gains or losses in inventories, making it similar to net profit figures used by US oil companies. BP's non-replacement cost net profit was USD 16.6 billion against USD 5.7 billion this time last year.
BP announced last month that it was buying back $8 billion of shares using money from the sale of its stake in Russian joint venture TNK-BP to Rosneft. BP now holds a total 19.75 percent interest in Rosneft.
The results come at a very uneasy time for the company, which has been functioning under a cloud since the 2010 well blowout in the Gulf of Mexico that killed 11 workers. Some 200 million gallons of oil spilled, smearing the shoreline of several states and fouling the Gulf of Mexico.

Even as it tries to deal with the aftermath of 2010, BP is streamlining and undergoing dramatic change, said equity analyst Keith Bowman of Hargreaves Lansdown Stockbrokers. He said the oil giant continues to shrink, with production down 5 percent year-over-year, "although new production opportunities are being cultivated."
"In all, underlying progress is being made," Bowman said. "However, until the uncertainty of US legal settlement is lifted, BP remains a higher risk investment in a traditionally lower risk sector, with consensus opinion currently denoting a hold, albeit a strong one."
The second phase of the trial will start in September. This part of the trial will explore BP's efforts to stop the flow of oil and assess how much spilled.
"While the final decision rests with the court, BP believes the evidence and testimony presented at trial confirms that it was not grossly negligent and that the accident was the result of multiple causes, involving multiple parties," the company said in a statement.
