Nov 29 (Reuters) - Daily oil output at Kazakhstan's giant Kashagan field dropped 38% to 33,000 metric tons on Tuesday due to a storm in the Black Sea which has disrupted the shipments of Kazakh crude, Kazakhstan's energy ministry said on Wednesday.

The disruption is expected to lower Kazakhstan's oil production by 631,700 metric tons this week, the ministry has said. (Reporting by Alla Afanasyeva Writing by Olzhas Auyezov Editing by Mark Potter)
