CASPER, Wyo. — With a 9-cent decline in the average price of gasoline, Natrona County continued to offer Wyoming’s cheapest fuel for the 11th straight week.
The nation’s average price of gasoline also fell 1.4 cents over the last week, standing at $2.99 per gallon, according to GasBuddy data compiled from more than 12 million individual price reports. The national average is down 14.8 cents from a month ago and 6.6 cents from a year ago.
The national average price of diesel has increased 2.5 cents in the last week to stand at $3.663 per gallon.
AAA reports a national average price of $3.03, down 2 cents from last week. Wyoming’s state average fell 1 cent to $2.92, AAA said.
“The national average once again briefly dipped below the $3 per gallon mark, but the drop will be short-lived,” said Patrick De Haan, head of petroleum analysis at GasBuddy. “Gas prices are likely to rebound soon in the Great Lakes states due to ongoing refinery challenges, while a new snag at a California refinery may slow the pace of declines on the West Coast. To top it off, OPEC+ announced another boost to oil production for December over the weekend, though they also signaled a pause in further increases from January through March.
“For now, expect the national average to hover in the low-$3 range, potentially drifting lower once refinery issues are resolved.”
The cheapest fuel in Natrona County on Monday is $2.38 at Shell, 3930 Denis Drive, followed by $2.44 at Sam’s Club, 4600 E. 2nd St., according to GasBuddy’s report.

OIL MARKET DYNAMICS
Over the last week, oil markets have been a bit more tame, balancing new sanctions on Russian oil exports with OPEC’s weekend decision to again raise oil production for the month of December, keeping oil prices in check. In early trade, WTI crude oil was down 3 cents to $60.95 per barrel, a slight drop from last Monday’s $61.53 per barrel fetch. Brent crude oil was also slightly lower in early trade, down 4 cents to $64.73, down from $65.96 last Monday. “Oil prices have moved nearly sideways in recent days. While there is rising skepticism that the latest sanctions on Russian oil companies remove substantial oil supply from the market, large US oil inventory draws last week kept prices supported,” added Giovanni Staunovo, UBS commodities analyst, in an e-mail. “The OPEC+ decision to pause their supply increases during the seasonal weaker Q1 demand period is also giving moderate support.”
