en.Wedoany.com Reported - Beacon Offshore Energy LLC is simultaneously advancing two development projects in the deepwater Gulf of Mexico: the Monument field has spudded its first development well, while the Zephyrus field has brought its second production well online.
Located at Walker Ridge Block 315, the Monument field's first development well reached a total depth of 32,250 feet, encountering 245 feet of net pay (true vertical thickness) in the Lower Wilcox reservoir, confirming pre-drill assessments of reservoir quality. The operator stated that Beacon will continue drilling a second development well before the two-well program is completed, with first oil from the Wilcox reservoir expected by the end of 2026.
The Monument field will be tied back to the Shenandoah floating production system, operated by Beacon, via two wells and a 17-mile subsea tieback system. This system serves as a regional hub platform specifically for the northwestern Walker Ridge area, covering the Shenandoah, Monument, and Shenandoah South fields. Partners include Navitas Petroleum and Talos Energy Inc.
At the Zephyrus field in Mississippi Canyon Block 759, the Zephyrus #2 well was completed in the first quarter of 2026 and began production in late April, with output from Miocene sandstone intervals.
The field already had the Zephyrus #1 well brought online at the end of 2025, and combined peak production from the two wells is expected to exceed 20,000 barrels of oil equivalent per day.
The Zephyrus development project ties back to the West Boreas subsea infrastructure operated by Shell plc, with produced fluids processed on the Olympus tension-leg platform in the Mars corridor. Partners include Houston Energy, HEQ II, Red Willow Offshore, Westlawn Americas Offshore, and Murphy Exploration & Production.
