Navitas Petroleum, holding 53% working interest in the LLOG-operated Shenandoah project in the northwest quadrant Â of the Walker Ridge (WR) protraction area in the deepwater central Gulf of Mexico, announced on 28 July 2020 that Beacon Offshore Energy (part of Blackstone Group) signed a preliminary agreement to acquire LOG's 30.95% stake in the project. This would increase Beacon's working interest from the current 15.95% to 46.9%. There was no mention whether Navitas or Beacon would assume operatorship.  Earlier this month, a USD 250 million contract was awarded to Transocean for drilling and completing services at Shenandoah using the "Deepwater Atlas" drillship which is still under construction. In the 15 July 2020 announcement, Transocean indicated a Final Investment Decision (FID) for the project is expected by 31 March 2021.  The development will include initial production from four wells (out of a total of eight), manufacturing and installation of subsea facilities, pipelines and a designated production platform. The platform will have a production capacity of over 70,000 boe/d and will be based on a regional-hub production model which LLOG successfully implemented at the Delta House and Who Dat fields. First oil for the field, which is estimated to hold 281 MMboe, is expected in 2023, but could be delayed.  The Shenandoah unit covers blocks WR 51 (G31938), WR 52 (G25232) and the northern half of WR 53 (G28148). The field, discovered by Anadarko in 2009, consists of Paleogene-aged reservoirs and sits in about 5,600 ft (1707 m) of water, approximately 171 mi (276 km) southwest of the onshore support base at Port Fourchon, Louisiana.
