Beacon Offshore Energy, a Texas-based exploration and production company, has brought its initial well on stream at a field in the Gulf of America (the U.S. Gulf of Mexico) and drilled another one, which is anticipated to begin production by the end of the first quarter of 2026.While confirming the start of oil and natural gas production from the Zephyrus field, Beacon Offshore Energy explained that the well came online in late December 2025. The initial discovery well (Zephyrus #1) was drilled by the U.S. player in 2023, encountering high-quality oil in the Middle Miocene Cris “I” aged M2 sand (M2).
The operator and its partners worked with Shell Offshore, a subsidiary of the UK-headquartered Shell, to connect the Zephyrus field to the existing West Boreas subsea infrastructure for further processing on the oil major’s operated Olympus production platform in the Mars Corridor.
“This efficient infrastructure-led development resulted in reduced emissions, lower development costs, and shortened time to first oil and was further made possible by incorporating a high integrity pressure protection system into the nine-mile Zephyrus subsea infrastructure,” according to Beacon.
The Miocene-aged Zephyrus development is located in the Mississippi Canyon Block 759, approximately 130 miles southeast of New Orleans, LA, in water depths ranging from 3,100 to 3,600 feet. The company drilled a second well at the field (Zephyrus #2), reaching a total measured depth of 26,270 feet
