Oct 8 (Reuters) -

The North Dakota Pipeline Authority said on Tuesday oil

production is estimated to be down nearly 60,000 to 90,000

barrels of oil per day (bpd) due to the ongoing wildfires in the

U.S. state.

It is the third-largest oil producing state in the country,

responsible for an output of 1.161 million bpd as of July,

according to data from the U.S. Energy Information

Administration.

"Associated wellhead natural gas production today is

estimated to be down 0.17-0.26 billion cubic feet per day

(bcfd)," Justin Kringstad, the director of the North Dakota

Pipeline Authority, said in an emailed response.

The state has been battling up to six wildfires since Oct.

6, which have led to two fatalities so far, according to local

media reports.

Earlier in the day, Exxon Mobil ( XOM ) said it had shut

some oil wells and production sites in North Dakota due to

multiple wildfires.

"Our teams are working with emergency responders to assess

the damage in areas where wildfires have passed. We will work

with industry partners and the local power co-ops to safely

restart wells and sites over the coming days," Exxon said in a

statement.
