UPDATE 1-Petrobras beats expectations with $2.7 bln Q2 profit
(Adds additional Petrobras results)
RIO DE JANEIRO, Aug 9 (Reuters) - Brazil's state-controlled oil company Petroleo Brasileiro SA on Friday reported second-quarter profit of 6.20 billion reais ($2.71 billion), reversing a year-earlier loss that was its first negative result in 13 years.
The result beat the average estimate of 5.08 billion reais of 12 analysts in a Thomson Reuters survey. In the second quarter of 2012, the company lost 1.35 billion reais.
Petrobras, as the Rio de Janeiro-based company is known, also reported that it had net sales, or total sales minus sales taxes, of 73.63 billion reais, 8.20 percent more than a year earlier and missing the survey's estimate of 75.06 billion reais.
Second-quarter earnings before interest, taxes, depreciation and amortization (EBITDA), a measure of the company's ability to generate profit from oil production, refining and other operations, rose 71 percent to 18.09 billion reais from the same quarter a year earlier.
The EBITDA result beat the survey average of 16.13 billion reais.
