In June 2001, PdVSA held its first non-associated Natural Gas licensing round for 11 exploration blocks, of which it awarded six. A consortium led by Total won the Yucal Placer Norte and Sur blocks, with other blocks awarded to Repsol-YPF, Pluspetrol, and Petrobras. In April 2004, Total began first production in the Yucal Placer blocks, with an initial output of 100 million cubic feet per day (MMcf/d). Through later stages of the project, Total planned to bring output up to 300 MMcf/d. The Yucal Placer blocks contain an estimated 1-2 Tcf of natural gas reserves. Repsol-YPF announced In December 2004 that it had made a gas discovery in the Barrancas Block, in southwest Venezuela, which contains an estimated 2-6 Tcf of natural gas reserves. The first phase of the project, scheduled for completion in late 2005, will feed an 80-MW power station in Portuguesa, with a second stage to supply a 450-MW power station in Obispos by the end of 2006.
