WTI, Brent Slip as U.S. Gasoline Average Falls Below $4

Oil benchmarks eased modestly on Tuesday, while U.S. gasoline prices slipped below $4 per gallon for the first time since mid-July, according to live pricing data and OilPrice.com.

WTI crude was quoted at $86.75 per barrel, down 12 cents, or 0.12%, in the day's live data. Brent crude traded at $92.10 per barrel, down 47 cents, or 0.51%. Natural gas rose 8 cents to $3.30.

For Bakken producers, the reported Bakken differential was minus $3.42 versus WTI. That places a Bakken crude price at about $83.33 per barrel, based on the live WTI quote and the differential.

The Bakken formation is North Dakota's primary oil-producing region, and many operators use WTI-linked pricing with a regional differential reflecting transportation, refining demand and basin-specific logistics.

The modest decline in crude came as retail fuel prices continued to ease. OilPrice.com reported that the national average regular gasoline price stood at $3.9788 per gallon as of early Tuesday, down from $4.1493 a week ago and from $4.3669 a month ago.

Prices remain well above the prior year. At this time last year, the national average was about $3.0707 per gallon, according to OilPrice.com. The outlet also said gasoline prices are still about 20% above the seasonal average.

Patrick De Haan, head of petroleum analysis at GasBuddy, told OilPrice.com that the U.S. is likely to see further declines and that the average gasoline price could fall to about $3.70 per gallon by Thanksgiving. He said prices may sink beyond that if the geopolitical situation remains in balance.

A lower gasoline average can signal softer seasonal fuel demand, which may weigh on crude prices, while still leaving retail prices above last year's levels.

The source attributed recent oil-price weakness to renewed hopes that a diplomatic push could lead to some form of an agreement between the United States and Iran.

Diesel, however, remained elevated. OilPrice.com reported the average U.S. diesel price at $6.1572 per gallon on Tuesday, compared with $3.7389 per gallon at the same time last year. It said Middle East fuel exports remain substantially below pre-war levels, contributing to tightness in the global diesel market.

For Bakken operators, the pricing picture splits into two segments. Crude realizations are being pressured by the lower WTI benchmark and the Bakken discount to WTI, while natural gas has moved higher. That mix can affect lease operating economics and royalty calculations, particularly where wells produce associated gas alongside oil.

Royalty owners and North Dakota producers will watch whether the seasonal demand decline and geopolitical developments continue to push crude lower, or whether tightness in refined products keeps oil prices supported. The Bakken differential remains a key number: at minus $3.42 versus WTI, it directly reduces the value of Bakken crude relative to the benchmark.

For royalty owners, realized prices depend on the sales contract, the benchmark, the differential and the value of natural gas. A Bakken discount, or a softer WTI print, can reduce the gross revenue pool available before deductions.
