Production of Sudan's Nile Blend has dropped to around 90,000 barrels per day (bpd), down from 100,000-110,000 bpd two months ago, an industry source said Friday. 

It was not immediately clear what had caused the fall in production. Of the total output, around 50,000 bpd is currently processed domestically, the source said, leaving approximately 40,000 bpd or around 1.2 million barrels a month for exports.

 The medium sweet grade is produced at Sudan's Block 2 and 4 operated by the Greater Nile Petroleum Operating Co., a joint venture between China National Petroleum Corp, Malaysia's Petronas and India's ONGC Videsh .

Production in South Sudan's Unity State was believed to be still down, after being halted in December due to violence in the region.

Petronas and ONGC Videsh are expected to jointly load a 600,000-barrel cargo in June, although the cargo had not been offered to potential buyers yet, the person said.
