Oil prices slipped on Tuesday, reversing earlier gains, as concerns of a possible global recession curtailing fuel demand outweighed supply disruption fears, highlighted by an expected production cut in Norway.

Brent crude fell $1.49, or 1.3%, to $112.01 a barrel by 1020 GMT.

U.S. West Texas Intermediate (WTI) crude fell 15 cents, or 0.1%, to $108.28 a barrel, from Friday's close. There was no settlement for WTI on Monday because of the Independence Day public holiday in the United States.

"Oil is still struggling to break out from its current recessionary malaise as the market pivots away from inflation to economic despair," Stephen Innes of SPI Asset Management said in a note.

Investors are becoming more concerned as the latest surge in gas and fuel prices added to worries about a recession.

In South Korea, inflation in June hit a near 24-year high, adding to concerns of slowing economic growth and oil demand.

Data showed business growth across the euro zone slowed further last month, with forward looking indicators suggesting the region could slip into decline this quarter as the cost of living crisis keeps consumers wary.

However, supply concerns still loomed. Earlier in the session, WTI rose more than $3 and Brent more than $1 on reports of output disruption in Norway.

Norwegian offshore workers began a strike that will reduce oil and gas output, the union leading the industrial action told Reuters.

The strike is expected to reduce oil and gas output by 89,000 barrels of oil equivalent per day (boepd), of which gas output makes up 27,500 boepd, Norwegian producer Equinor has said.

"Oil prices are ... benefiting from the strike in Norway, so far impacting only modest volumes, and the sharp increase in Saudi official selling prices for August, suggesting that Saudi exports might not increase that much next month," UBS analyst Giovanni Staunovo said.

Saudi Arabia, the world's top oil exporter, raised August crude oil prices for Asian buyers to near record levels amid tight supply and robust demand.

The official selling price (OSP) for August-loading Arab Light to Asia was raised by $2.80 a barrel from July to $9.30 a barrel over Oman/Dubai quotes, people familiar with the matter said, close to the record high premium of $9.35 per barrel hit in May.

"We suspect corrections in the energy market during the second quarter may end up being short-lived, with the risk of a prolonged period of high prices the most likely outcome," said Ole Hansen, head of commodity strategy at Saxo Bank, adding prices would trade within a wide range of $100 to $125.
