Energy selloff deepens as crude slides; Diamondback, Noble, peers hit hard

Energy equities came under heavy selling pressure on Wednesday, with oil and gas producers and drilling companies posting steep losses as crude oil prices pulled back sharply from recent highs.

October West Texas Intermediate crude fell $3.40, or 3.21%, to settle lower, according to Nasdaq. The decline accelerated after weekly U.S. Energy Information Administration data showed crude inventories fell by only 640,000 barrels — a smaller draw than the expected 1.5 million barrels — while gasoline supplies rose unexpectedly by 794,000 barrels. A rally in the U.S. dollar index to a 1.5-month high also weighed on energy prices.

Nasdaq reported that losses deepened after U.S. Energy Secretary Wright said 18 million barrels of crude and refined products moved through the Strait of Hormuz on Tuesday, easing global supply concerns. Additional pressure came from Saudi Arabia’s statement that it aims to restore about half the capacity of its East-West pipeline within days, following a shutdown last week due to drone strikes. The 750-mile pipeline, which normally carries 7 million barrels per day, was closed late Friday after Houthi rebel attacks.

Diamondback Energy fell 8.2% to $194.18 on volume of 4.6 million shares, according to AlphaStreet. The Permian Basin-focused producer was among the hardest hit in the sector. At least eight peers posted significant declines alongside Diamondback, with EOG Resources down 5.5%, ConocoPhillips off 4.8%, Devon Energy falling 4.3%, and EQT dropping 3.9%. AlphaStreet noted that no company-specific news — no earnings miss, analyst downgrade, or operational warning — drove the decline; instead, investors fled the entire exploration and production space.

Noble Corporation shares sank 5.9% to $43.78, AlphaStreet reported. The offshore driller was part of a broader coordinated decline in the drilling sector: KEGX plunged 9.3%, PTEN dropped 6.5%, and HP fell 4.8%. The synchronized move pointed to shifting sentiment around crude oil prices and rig demand, rather than company-specific issues, according to AlphaStreet. Trading volume for Noble reached 546,639 shares.

Occidental Petroleum also traded lower on Wednesday, with Benzinga reporting that energy equities experienced broad profit-taking alongside the crude pullback. No specific percentage decline for Occidental was provided in the summary source.

The combined selloff reflects renewed concern about oil market fundamentals. While supply risks from the Middle East and Ukraine have supported crude in recent weeks — including a 3.75-month high on Tuesday after Saudi Arabia’s pipeline shutdown — Wednesday’s data and commentary suggested some near-term easing. Nasdaq noted that the International Energy Agency last Friday warned that high oil prices and restricted supply would cause the biggest drop in global oil demand this year since the Covid-19 pandemic, though it also raised its 2025 global oil deficit estimate to 1.7 million barrels per day due to the US-Iran conflict.

For energy producers and drillers, softer crude prices often translate into tighter exploration budgets and pressure on rig contracts and dayrates. The sharp, synchronized declines across multiple subsectors indicate that investors are repricing near-term expectations, according to AlphaStreet’s analysis. Diamondback’s 8.2% drop outpaced most majors, suggesting heavier selling pressure or less defensive positioning among its shareholder base.

The Energy Information Administration’s weekly report was described as mostly bearish for crude and products. EIA crude inventories fell 640,000 barrels versus a 1.5 million barrel draw expected, while gasoline supplies rose by 794,000 barrels. Distillate supplies also increased more than anticipated.
