据石油和天然气管道新闻5月15日消息，欧佩克4月份的石油产量出现下滑，而该组织预计2019年的需求将增加，这表明供应将出现紧缩现象。
欧佩克在其月度石油报告中称，该组织4月日产量环比下降3,000桶，至3,031万桶。尽管产量小幅下降，沙特的日产量也减少4.5万桶。
与此同时，预计今年全球石油需求每天将增加121万桶，达到平均每天9994万桶，2019年欧佩克原油需求每天也将增加30万桶，达到每天3060万桶。
欧佩克还预计美国石油产量将下降。这是由于制约因素限制了向美国墨西哥湾沿岸输送二叠纪石油的能力，以及主要页岩区块较低的钻探和完井活动造成的影响。
预计2019年美国页岩油日产量较上年同期增长132万桶，达到平均788万桶，较2018年预估减少28万桶。

OPEC reduces output while demand rises
OPEC’s April oil output slipped in April, while the oil exporting group projected increased demand in 2019, signalling a crunch in supply.
The Organization of Petroleum Exporting Countries (OPEC) said in its monthly oil report the group’s April output declined by 3,000 barrels per day (bpd) month-on-month to 30.031 million bpd. Although a small decline, Saudi Arabia also reduced output by 45,000 bpd.
Meanwhile, world oil demand for the year is projected to increase by 1.21 million bpd, to average 99.94 million bpd and demand for OPEC crude in 2019 was also revised up by 300,000 bpd to 30.6 million bpd.
OPEC also expects lower production from U.S due to fundamental constraints, mainly limited pipeline capacity to transfer Permian oil to the US Gulf Coast (USGC) as well as lower drilling and completion activity in main shale plays.
Year-on-year growth in U.S. tight crude output for 2019 is forecast at a slower pace of 1.32 million bpd to average 7.88 million bpd, which is 0.28 million bpd less than estimated for 2018.
