Iran has shut down a number of oil wells in the Khuzestan province due to massive floods hitting the country’s south, according to Mehr news agency, Reuters reported.

Closing the wells led to a production loss of up to 20,000 barrels per day (b/d) of crude oil.

“There are no oil leaks at the Hoor al-Azim wetland area. We have closed 10 to 12 oil wells there, as a precautionary measure to prevent any environmental damages,” said Touraj Dehghani, Head of Iran’s Petroleum Engineering and Development Company (PEDEC).

Iranian authorities say oil exports have not been affected by the floods.
