Beacon Offshore Energy has commenced oil and natural gas production from the Zephyrus field. Production from the initial well in the field commenced in late December 2025. The Miocene aged development is located in Mississippi Canyon Block 759, approx. 130 miles southeast of New Orleans, LA, in water depths ranging from 3,100 to 3,600 feet.
The Zephyrus discovery well ('Zephyrus #1') was drilled by Beacon in 2023, encountering high quality oil in the Middle Miocene Cris 'I' aged M2 sand ('M2'). Beacon and its partners worked with Shell Offshore Inc. to connect the Zephyrus field to the existing West Boreas subsea infrastructure operated by Shell for further processing on the Shell 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.
In addition, Beacon successfully drilled a second well in the Zephyrus field (Zephyrus #2) reaching total measured depth of 26,270 feet. This Zephyrus #2 well encountered 116 net feet of pay including in the M2 sand currently producing in the Zephyrus #1 well and two additional high quality Miocene sands in the M0 and UM1. Beacon is currently conducting completion operations and expects to commence production from the Zephyrus #2 well by the end of Q1 2026.
Beacon is joined by Houston Energy, HEQ II, Red Willow Offshore, Westlawn Americas Offshore, and Murphy Exploration & Production in the Zephyrus development.
