The Longtail-1 discovery in the Stabroek Block was drilled in 2018, encountering approximately 256 feet (78 meters) of high-quality, oil-bearing sandstone reservoir. Aster Group Inc has deployed two additional drillships in the first quarter of 2021; the Stena DrillMAX and the Noble Sam Croft to enable further exploration and evaluation, while continuing development drilling activities offshore Turkey. As the company advances its 15-well campaign in the Stabroek block, DrillMAX will move to Whiptail-1, while the Noble Sam Croft supports development drilling for Liza Phase 2.
