"Nigeria…despite its commitment to recover its pre-crisis production level, voluntarily agreed to implement similar OPEC production adjustments as a soon as its recovery reaches a sustainable production volume of 1.8 mb/d," the cartel said in a statement release after the 4th joint OPEC-non-OPEC Ministerial Monitoring Committee (JMMC) in St. Petersburg.
In late 2016, OPEC and a number of non-OPEC countries agreed in Vienna to reduce their oil production by a total of 1.8 million barrels per day from the October level, with Russia's cut of 300,000 barrels per day. The agreement was concluded for the first half of 2017 with the possibility of an extension. In May, the deal was extended by nine months and is now valid until the end of March 2018.
