France's Total reported a 7.8% decline in second-quarter adjusted net profit to €3.10 billion as lower gas prices and a weaker dollar exchange rate outweighed a rebound in production.
Total bucked an industry-wide trend of falling oil and gas output as its new 220,000 barrel-per-day Dalia field in offshore Angola came on stream, helping to lift production by 1.4%.
It's results compared with a 5% rise in Royal Dutch Shell's underlying profits, and a 12.5% drop in BP's adjusted quarterly net income.
Operating profit slipped 13.7% to €5.76 billion, squeezed by the combination of a weaker dollar, lower gas prices, cost inflation and increased exploration.
Sales fell 4.4% to €39.09 billion - or nearly €5,000 earned per second during the second quarter.
Analysts had forecast average net income of €3.054 billion and operating profit of €5.849 billion.
Total made no comment on its outlook for oil and gas output, which although higher in the first half, was capped by lower OPEC quotas, new disruptions in Nigeria and halted production at its Congo oilfield.
