Of the eight RPSA contracts originally awarded by PdVSA, three resulted in the discovery of significant amounts of Oil reserves: La Ceiba, Golfo de Paria Este and Golfo de Paria Oeste (West). ConocoPhillips, the Operator of the Golfo of Paria Oeste block, plans to bring the 55,000-bbl/d Corocoro field onstream, along with equity partners PdVSA (35 percent) and Eni (26 percent). Originally slated for start-up in 2006, first production will now likely not occur until 2007. ConocoPhillips is also actively exploring in its Golfo de Paria Este block.
