The company’s businesses are divided in three major segments: Upstream, Downstream, and Other Businesses. The Downstream sector is by far the largest segment, generating over 90 percent of BP’s total revenues. Downstream generally includes the processing and final distribution of fuels, lubricants and petrochemicals. North America and Africa are the most important regions for BP’s oil production.
BP was linked with a number of environmental, health, and safety violations over the last few decades. The latest and most remembered accident is the Deepwater Horizon oil spill in the Gulf of Mexico in April 2010, the largest marine oil spill in history. The U.S. government estimated the quantity of spilled oil at some 4.9 million barrels. Until year-end of 2013, the oil spill has cost the company some 28 billion U.S. dollars due to various payments.
