Iraq’s West Qurna 2 oilfield has been temporarily shut down for maintenance until March 2, according to a state oil official familiar with the field’s operations.

According to the official, the upkeep involved drilling new wells and connecting new pipes. He talked on the condition of anonymity because he was not permitted to make public remarks.

West Qurna 2 produces around 400,000 barrels of crude oil per day (bpd). Iraq, OPEC’s second-largest production, shipped 3.2 million barrels per day on average in January, according to its oil ministry.

According to a Reuters source, Iraq will make up for the output gap later.

The outage of West Qurna 2 will extend until March 14, according to the Iraq Oil Report, an industry publication.
