WTI Holds Above $91 as Crude Inventories Tighten

Front-month West Texas Intermediate (WTI) crude oil futures held above $91 per barrel in quiet Sunday trading, supported by a reported drawdown in U.S. commercial inventories. WTI for October delivery traded at $91.48, a marginal gain of 18 cents. The global Brent benchmark saw a stronger increase, rising 76 cents to $96.28 per barrel, according to live price data.

The price support follows data from the U.S. Energy Information Administration (EIA) showing a reduction in nationwide crude stocks. According to Rigzone, crude oil inventories, excluding the Strategic Petroleum Reserve, stood at 424.5 million barrels for the week ending August 28. This week-on-week drawdown indicates ongoing firm demand relative to supply.

The Bakken discount to the WTI benchmark was recorded at -$3.42 per barrel. This differential, which represents the price adjustment for Bakken crude delivered at Clearbrook, Minnesota, is a key metric for North Dakota producers' realized revenue. A stable or narrowing discount in a rising price environment improves wellhead economics for operators across the Williston Basin.

Natural gas prices also saw upward movement, with the front-month contract trading at $2.98 per MMBtu, an increase of six cents. While not a primary driver for most Bakken operators, associated gas revenues contribute to overall project economics.

Market attention remains focused on global supply fundamentals. A separate Rigzone report highlighted the significant, low-cost resource potential of Argentina's Vaca Muerta shale play, estimated to hold 9 billion barrels of oil resource breakeven below $55 per barrel. Andy McConn, director of consultancy EIR, stated that "Vaca Muerta's growth potential and low-cost competitiveness are a rare combination in today's upstream market." This underscores the long-term competitive landscape for international shale plays, though it does not pose an immediate threat to current Bakken supply.

For Bakken operators, the current price environment above $90 WTI, coupled with a differential under $3.50, continues to support strong cash flows and drilling activity. The inventory draw reported by the EIA reinforces the narrative of a tightening physical market, which helps underpin prices. However, traders are likely exercising caution with the U.S. observing the Labor Day holiday on Monday, expecting lighter volume and potential volatility when full trading resumes.

The sustained high prices are a positive signal for continued capital discipline and shareholder returns among publicly traded producers, as well as for the state's oil extraction tax revenues. Operators will be watching for the next EIA weekly report and any signals from OPEC+ regarding production policy for the fourth quarter.
