Petróleos de Venezuela, S.A. is the Venezuelan state-owned oil and natural gas company. It has activities in exploration, production, refining and exporting oil, as well as exploration and production of natural gas. Since its founding on 1 January 1976 with the nationalization of the Venezuelan oil industry, PDVSA has dominated the oil industry of Venezuela, the world's fifth largest oil exporter.Oil reserves in Venezuela are the largest in the world, and the state-owned PDVSA provides the government of Venezuela with substantial funding resources. The government of Venezuela treats PDVSA as a cash-cow, and the company only hires political supporters of the president. Between 2004 and 2010 PDVSA contributed $61.4 billion to the government's social development projects. Around half of this went directly to various Bolivarian Missions, with the remainder distributed via the National Development Fund. Incompetence has led to serious inefficiencies and accidents.

Method for operating a two-stage hydroprocessing system includes introducing a feedstock and a first-stage gas to a first reaction zone a first pressure to generate a first-stage product stream; introducing the first-stage product stream to a first separation unit to separate an intermediate feedstock from a spent gas; introducing the intermediate feedstock and a second-stage gas to a second reaction zone a second pressure which is greater than the first pressure to generate a second-stage product stream; introducing the second-stage product stream to a second separation unit to separate a hydroprocessed product and an intermediate gas; feeding the intermediate gas directly to the first reaction zone as the first-stage gas; feeding spent gas to an amine unit and then compressor to generate recycled gas; and feeding recycled gas to the second reaction zone as the second-stage gas.
