Exxon Mobil Corp. (NYSE: XOM) will focus on drilling and production in Brazil now that it has made extensive acquisitions of oil blocks in the country, the company’s CEO in Brazil, Carla Lacerda, said on Sept. 27.

Exxon also sees new opportunities in Brazil’s biofuels, bioenergy and gas sectors, Lacerda said during a panel discussion at the Rio Oil & Gas convention in Rio de Janeiro.

“We are principally in the exploration phase so my big task now is to drill some wells so that we can start up production some day,” Lacerda said.

Exxon has plowed big money into Brazil to replenish its dwindling reserves, starting with an oil auction in September 2017. Before that, it was among the few oil majors without an exploration presence in Brazil's pre-salt, where billions of barrels of oil are trapped under a thick layer of salt beneath the ocean floor.

The American oil major is expected to bet big on Sept. 28 in an oil auction that could be its last crack at Brazil’s coveted offshore oil for another four years, as a wide-open election spurs fears about barriers to foreign investment.
