Oil futures edged higher, extending gains on the prospect of Opec+ deepening supply cuts to shore up prices that have fallen for four weeks on demand concerns and Middle East supply disruption owing to the Israel-Hamas conflict.
Brent crude futures rose 34 cents to $80.95 a barrel by 0915 GMT. US West Texas Intermediate crude was up 31 cents at $76.20.
The front-month December WTI contract expires later on Monday while the more active January futures gained 38 cents to $76.42.
Both contracts settled 4 per cent higher on Friday after three OPEC+ sources told Reuters that the producer group, comprising the Organization of the Petroleum Exporting Countries (Opec) and allies including Russia, is set to consider whether to make additional supply cuts when it meets on November 26.
Oil prices have dropped by almost 20 per cent since late September while prompt inter-month spreads for Brent and WTI slipped into contango last week. In a contango market prompt prices are lower than those in future months, signalling sufficient supply.
"In light of last week's obliteration of oil bulls, some kind of response was forthcoming from the (Opec) producer group," said Tamas Varga of oil broker PVM.
"If additional cuts are agreed, a short-term price boost is expected, but its longer-term price impact seems dubious as enforcement and adherence will be the salient issue."
Investors are also keeping an eye on Russian crude oil trade after Washington imposed sanctions on three ships that have sent Sokol crude to India.
On Friday Moscow lifted a ban on gasoline exports which could add to global supplies of the motor fuel. That came after Russia scrapped most restrictions on exports of diesel last month.
US energy companies last week added oil and gas rigs for the first time in three weeks, energy services business Baker Hughes said on Friday. The oil and gas rig count serves as an early indicator of future output.
In the Middle East, US and Israeli officials said a deal to free some of the hostages held in the besieged Gaza enclave was edging closer despite fierce fighting. -Reuters
