UPDATE 1-Pemex says Ku Maloob Zaap field producing at peak

VERACRUZ, Mexico, June 11 (Reuters) - Mexico's Ku Maloob Zaap oil field is currently producing at a peak 830,000 bpd and will continue to produce at that level for the next seven years, Hector Salgado, an engineer at the state-run oil company Pemex, told reporters on Thursday.

Pemex officials said earlier this year the field, which is now Mexico's single largest producer of oil, could begin to decline in 2010.

"We now think that Ku Maloob Zaap will produce at this level for seven more years," Salgado said following a presentation which described a multi-year study that re-evaluated the potential of the Ku Maloob Zaap field.

Ku Maloob Zaap overtook the Cantarell field as Mexico's most productive oil field this spring. Pemex has been struggling to replace output lost at Cantarell due to natural declines. (Reporting by Robert Campbell)
