US West Texas Intermediate (WTI) crude oil futures were at $ 53.64 per barrel at 0138 GMT, up 54 cents, or 1 per cent, from their last close.
International Brent crude futures were up 0.9 per cent, or 53 cents, at $ 62.95 per barrel.
Jeffrey Halley, senior market analyst at futures brokerage OANDA in Singapore said oil prices were boosted after “Saudi Arabia announced it was cutting daily production and exports by a further 500,000 barrels per day (bpd) on top of its agreed OPEC quota cut”.
The Organization of the Petroleum Exporting Countries (OPEC), which Saudi Arabia de-facto leads as the world’s top crude oil exporter, said on Tuesday that it had cut its output by almost 800,000 bpd in January to 30.81 million bpd.
Supply issues in Venezuela, another OPEC member, are also bolstering oil markets as the South American country suffers a political and economic crisis, with Washington introducing petroleum export sanctions against state-owned energy firm PDVSA.
Despite the political rifts between Venezuela and the United States, American refiners have in the past been some of the biggest customers of Venezuelan crude. These customers have fallen away after Washington imposed sanctions earlier this year.
Venezuela has tried to find alternative customers, especially in Asia, but under US pressure many buyers there are also shying away from dealing with PDVSA.
“Oil production is rapidly falling and companies that normally resell Venezuelan crude have not found ways to mitigate the effect of the US sanction,” Barclays bank said in a note issued on Tuesday.
