But Total and oil majors have been under increasing political pressure from the United States and its allies over their activities in Iran amid mounting tensions over Iran's nuclear program, which the U.S. and other countries fear is aimed at building weapons but Tehran insists is for producing nuclear energy.

The standoff heightened Wednesday when Iran test-fired long- and medium-range missiles during war games to show it could retaliate against any U.S. or Israeli attack.
The French foreign minister last year urged Total and national gas giant Gaz de France to refrain from investing in Iran.
"Today we would be taking too much political risk to invest in Iran because people will say, 'Total will do anything for money,"' Chief Executive Christophe de Margerie was quoted by the Financial Times as saying Thursday.
Neither the company spokeswoman nor the CEO would say whether Total was pulling out of South Pars or overall investment in Iran.
"Iran remains a priority country in the strategy of Total," Wiler said. "We are still in contact" with Iranian partners, she said.
De Margerie expressed frustration at U.S. pressure on European energy investors in the countries.
