Scheduled to commence in mid-May 2026, the project will be situated at Block 15-2/01 offshore Vietnam's continental shelf. To facilitate this campaign, PV Drilling has successfully mobilized the Gunnlod rig from its strategic partner, Borr Drilling, to provide comprehensive services to Thang Long JOC.
