In a monthly report, the Organization of the Petroleum Exporting Countries said non-OPEC producers would boost supply by 1.66 million barrels per day in 2018. That was the fourth straight rise from 870,000 bpd forecast in November, Reuters reported.
"For 2018, higher growth is expected on the back of the projected increase in US shale production following a better price environment not only for shale producers, but also for other countries such as Canada, the UK, Brazil and China," OPEC said of the outlook for non-OPEC supply.
This would lead to "a higher quarterly distribution throughout the year with a record-high level projected for the fourth quarter", OPEC said.
OPEC, Russia and several other non-OPEC producers, but not the United States, began to cut supply in January 2017 in an effort to erase a global glut of crude that had built up since 2014. They have extended the pact until the end of 2018.
The deal has helped boost oil prices, which topped $71 a barrel this year for the first time since 2014 and were near $65 on Wednesday. But it has also encouraged a flood of shale, fueling a debate about the curbs' effectiveness.
Oil pared much of an earlier gain on Wednesday after the release of the OPEC report.
Iran's Oil Minister Bijan Namdar Zanganeh has said OPEC could agree at its next meeting in June to start easing the curbs in 2019.
He also said OPEC should aim for oil around $60 to contain shale growth.
Top exporter Saudi Arabia, however, said in February it was premature to discuss an exit strategy.
Faster-than-expected growth in demand due to a robust world economy has added a tailwind to the OPEC supply effort.
Although OPEC, in the report, slightly raised its estimate of growth in world demand to 1.6 mbd, it now projects the expansion in supply outside the group will exceed gains in demand.
This brings OPEC's view closer to that of the International Energy Agency, which expects a less rosy 2018 supply/demand balance.
