ExxonMobil has made a discovery at Longtail-3 in the Stabroek Block offshore Guyana. Drilling at Longtail-3 encountered 230 feet of net pay, including newly identified, high quality hydrocarbon bearing reservoirs below the original Longtail-1 discovery intervals. The well is located approximately two miles south of the Longtail-1 well. It was drilled in more than 6,100 feet of water by the Stena DrillMAX. The Longtail-1 discovery in the Stabroek Block was drilled in 2018, encountering approximately 256 feet of high-quality, oil-bearing sandstone reservoir. ExxonMobil 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 Guyana. 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. In other drilling activity in the Stabroek Block, the Mako-2 evaluation well confirmed the quality, thickness and areal extent of the reservoir. When integrated with the previously announced discovery at Uaru-2, the data supports a potential fifth floating production storage and offloading vessel in the area east of the Liza complex. The Koebi-1 exploration well in the Stabroek block has shown evidence of non-commercial hydrocarbons. By the first quarter of this year more than 2,600 Guyanese and 600 local suppliers were supporting ExxonMobil’s activities in country. Guyanese staff have completed more than 40,000 hours of training in Guyana, Trinidad and Tobago, and the United States. The Stabroek Block is 6.6 million acres (26,800 square kilometers). ExxonMobil affiliate Esso Exploration and Production Guyana Limited is operator and holds 45 percent interest in the Stabroek Block. Hess Guyana Exploration Ltd. holds 30 percent interest and CNOOC Petroleum Guyana Limited, a wholly-owned subsidiary of CNOOC Limited, holds 25 percent interest.
