Occidental Petroleum (NYSE: OXY) announced Thursday that it has drilled into a significant oil accumulation in the deepwater Gulf of America, previously known as the Gulf of Mexico. The Bandit exploration well, located in Green Canyon Block 680, encountered a thick section of high-quality, oil-bearing sandstone—a discovery that not only bolsters Occidental’s portfolio but also hands a tidy deepwater win to its joint-venture partners Chevron (NYSE: CVX) and Woodside Energy (NYSE: WDS).
Geologists described the pay zone as “full-to-base” high-quality sand, indicating excellent reservoir continuity and high oil saturation, which typically translates to substantial per-well recoverable volumes. Occidental and its co-owners are currently evaluating data to determine next steps, with early plans pointing toward a subsea tie-back to a nearby Occidental-operated production facility. If executed, such a development scheme would drastically lower capital costs and accelerate the project’s path to first oil.
The Bandit prospect is a textbook deepwater joint venture. Occidental, the operator, holds a 45.375% working interest. Chevron follows with 37.125%, while Australia’s Woodside Energy retains 17.5%. For Chevron, the discovery reinforces its already formidable Gulf of America footprint. For Woodside Energy, it validates the company’s strategic pivot toward expanding its U.S. deepwater exposure. With crude prices buoyed by ongoing geopolitical friction, the marginal value of new ultra-deepwater barrels has rarely been higher.
Yet the significance of Bandit extends beyond the raw resource count. The well, drilled to a depth exceeding 40,000 feet, ranks among the deepest ever attempted in the Gulf. Successfully navigating the extreme pressures and temperatures at such depths represents an engineering milestone in its own right. Industry analysts estimate that a successful development in this fairway could yield upwards of 230 million barrels of oil equivalent (BOE) per well—a figure that dwarfs the average well performance in the Permian Basin.
“This discovery demonstrates the continued importance of the Gulf of America as a strategic source of reliable domestic oil supply that supports long-term energy security,” said Jeff Simmons, Senior Vice President, Subsurface Technology and Chief Petrotechnical Officer at Occidental.
The timing of the announcement adds an extra layer of market resonance. Shares of Occidental, Chevron, and Woodside Energy have all posted robust gains this year on the back of elevated oil prices tied to geopolitical instability. The Bandit breakthrough delivers a fresh dose of certainty to the deepwater sector. While the global debate over the pace of the energy transition rages on, the seabed of the Gulf of America is quietly laying down the next line of defense for U.S. production.
