The Government of Angola forecasts oil output will rise by 10 percent in 2015, to average 1.84 million barrels per day, according to a revised 2015 budget passed by Parliament last week.

The new budget states the overall oil output will reach 669.8 million barrels for full-year 2015.

Oil accounts for around half of Angola’s gross domestic product, 80 percent of tax revenues and 90 percent of export earnings, Reuters news agency reports.

The Portuguese-speaking country is Africa’s second largest oil exporter. Several major international oil producers have operations in Angola, including China’s Sinopec.

Iraq in January overtook Angola to become China’s second-largest oil supplier, just behind Saudi Arabia.

Angola’s state oil company Sonangol is expected to auction 15 new oil and gas blocks this year, the company’s Chairman, Francisco de Lemos Jose Maria, said last month.
