Ghana has became the world's latest oil producer, pumping oil for the first time from a field off the country's Atlantic coast.
The opening of the valves comes just three years after the discovery of the oil -- one of the largest recent oil discoveries in West Africa.
Initial commercial production is expected to generate around $1 billion of annual crude revenues, making Ghana the sub-Saharan Africa's seventh-largest oil producer.
Ghana's parliament is still debating proposed laws to regulate the industry.
