* U.S. sanctions on Iran, Venezuela tighten markets
* But soaring U.S. shale output offsets some of the disruptions
* Economic slowdown to weigh on oil prices by Q4 -BNP Paribas

SINGAPORE, Feb 20 (Reuters) - Oil prices hovered near 2019 highs on Wednesday, supported by OPEC-led supply cuts and U.S. sanctions on Iran and Venezuela, but capped by soaring U.S. production and expectations of an economic slowdown.
U.S. West Texas Intermediate (WTI) crude oil futures CLc1 were at $55.93 per barrel at 0042 GMT, down 16 cents from their last settlement, but not far off their 2019 high of $56.33 reached earlier this week.
International Brent crude futures LCOc1 had yet to trade. They also hit a 2019 high of $66.83 per barrel this week.
Prices have been driven up by supply cuts led by the Organization of the Petroleum Exporting Countries (OPEC).
OPEC's - and the world's - biggest oil exporter Saudi Arabia is expected to reduce shipments of light crude oil to Asia in March as part of the effort to tighten markets. as well as some non-affiliated producers such as Russia agreed late last year to cut output by 1.2 million barrels per day (bpd) to prevent a large supply overhang from swelling.
"We have lowered Saudi crude oil output in line with announcements ... (and) are now assuming that Saudi Arabia will produce in the first three quarters of 2019 less than the 10.31 million bpd target it agreed to at the 7 December OPEC, non-OPEC meeting," French bank BNP Paribas (PA:BNPP) said in a note.
Because of the cuts, BNP said it expected oil prices "to rally through Q3 2019", with Brent to average $73 per barrel by then and WTI to average $66.
Another key oil price driver has been U.S. sanctions on oil exporters Iran and Venezuela.
Despite the sanctions, Iran's crude exports were higher than expected in January, averaging around 1.25 million bpd, according to Refinitiv ship tracking data. Many analysts had expected Iran oil exports to drop below 1 million bpd after the imposition of U.S. sanctions last November. against the supply cuts and sanctions is U.S. crude output C-OUT-T-EIA , which soared by more than 2 million bpd in 2018 to a record 11.9 million bpd, thanks to booming shale oil production, which the Energy Information Administration on Tuesday said was expected to keep rising. Paribas said surging U.S. output would feed into lower oil prices towards the end of the year, with Brent to dip to an average of $67 a barrel by the fourth quarter and WTI to average $61.
"U.S. oil production growth, driven by shale, will be increasingly exported in greater volumes to international markets while the global economy is expected to witness a synchronised slowdown in growth," the bank said.
