Beacon Offshore Energy LLC has begun production at its Shenandoah Field in the Gulf of America, the deepwater upstream company said July 25.
The Shenandoah floating production system (FPS) is located on the Walker Ridge, 150 miles off the coast of Louisiana. It’s in a water depth of approximately 5,800 ft with a nameplate capacity of 120,000 bbl/d and 140 MMcf/d.
Production from the first of four producing wells began on July 25. Beacon will ramp up first-phase production during the third quarter with a target of 100,000 bbl/d.
First production comes a month later than originally expected. Beacon had said the FPS was in its final stages of being hooked up and commissioned in May.
Shenandoah’s reserves are located at reservoir depths of approximately 30,000 ft true vertical depth and are being developed using high pressure 20,000 psi technology, Beacon said. The company expects to use the technology at other similarly situated fields in the Inboard Wilcox trend.
Shenandoah was developed as a regional host of additional discoveries, including the Beacon-operated Monument and Shenandoah South. Together with Shenandoah, the discoveries are expected to hold recoverable resources of almost 600 MMboe.
Beacon has sanctioned the development of the Shenandoah South discovery in Walker Ridge 95 in water depths ranging from 5,800 ft to 6,000 ft. The E&P will connect a subsea tieback development to Shenandoah FPS via a 3-mile flowline and a dedicated riser connection.
Shenandoah South will involve the drilling and completion of two wells, with initial production from the first well expected in second-quarter 2028. Beacon said 74 MMboe of 2P resource is expected from Shenandoah South.
