Such an agreement would need to achieve four things : fix a realistic new overall ceiling on opec ' s annual production ( which means 16 million barrels a day or less ) ; be sufficiently flexible to allow output to adjust to the sharp seasonal swings in world oil demand ; see that individual countries ' production quotas are both observed and effectively policed and look like lasting whatever happens to non - opec output 这样一个协议应当解决四个方面的问题：一是，从总体上为欧佩克制定一个新的、切实的年度产量上限（意味着每天1600万桶或更少） ；二是，在世界石油需求季节性剧烈波动面前给予充分的灵活性，允许对产量进行调整；三是，确保每个国家均按照配额生产并且得到有效的监控；四是，不论非欧佩克成员国的石油输出如何变化，恒守自己的原则。
