The Organization of the Petroleum Exporting Countries and Azerbaijan are discussing deepening cooperation, including possible Azeri membership of OPEC, two sources familiar with the talks told Reuters on Monday. Azerbaijan, along with some other non-OPEC nations led by Russia, and OPEC are cutting oil production jointly by 1.8 million barrels per day (bpd) in an effort to stabilize oil markets and boost the price of crude. The arrangement is due to run until the end of this year.  OPEC Secretary-General Mohammad Barkindo visited Baku from March 17-19, holding talks with Azeri President Ilham Aliyev on Sunday and with Energy Minister Parviz Shahbazov on Monday.  “Barkindo and the energy minister discussed prospects of future cooperation between Azerbaijan and OPEC,” one of the sources said. “There are three options. First – OPEC membership, the second – to become an associate member and the third – to continue cooperation the way it is now.”
