ALMATY, April 2 (Reuters) - An ecological organisation in Kazakhstan said on Tuesday that a European satellite had spotted an oil spill in the northern Caspian Sea near Kazakhstan's giant Kashagan oil field.

Kashagan, one of Kazakhstan's largest oil fields, is being developed by the North Caspian Operating Company (NCOC) consortium, which includes Shell, Eni, TotalEnergies and Exxon Mobil.

The Kazakh energy ministry, the consortium and the environment ministry did not immediately respond to Reuters questions about the alleged spill, which was reported by the Globus environmental group. (Reporting by Reuters)
