OREANDA-NEWS. Mexico's main oil-producing complex will start to decline in late 2017, state-run Pemex says.

Shallow-water Ku-Maloob-Zaap (KMZ) became Mexico's largest oil producing field in 2009, displacing the historic Cantarell complex which remains in decline.

Pemex upstream director Gustavo Hernandez Garcia told delegates at an oil conference in Stavanger, Norway, today that the company is working to extend the life of KMZ.

"We have been working to manage that decline, to extend the recovery factor of that field, because it is highly productive," he said.

KMZ currently produces around 850,000 b/d and includes the three fields in its name plus the Bacab and Lum fields, located in Campeche bay.
