Kaieteur News – ExxonMobil Guyana Limited (EMGL) has commenced drilling operations at two separate well sites in the Stabroek Block. This is according to notices published by the Maritime Administration Department (MARAD).
MARAD said that EMGL began drilling at the Hamlet-1 well site on June 15, 2025. The drillship MODU Stena Carron will carry out operations at this location until August 31, 2025. The Hamlet-1 well site is located approximately 104.40 nautical miles (193.40 kilometres) off the coast of Guyana and covers an area of 0.29 square nautical miles (1 square kilometre).
The Hamlet-1 prospect was previously identified by EMGL President Alistair Routledge as a key target for new potential oil discoveries. In February this year, Routledge said the company had identified Hamlet-1 as a priority well in the southeast portion of the Stabroek Block, adding, “That well will be called Hamlet- the Hamlet One well. That’s actually looking for an oil play in the southeast portion of the Stabroek Block,” Routledge added.”
Meanwhile, in another notice, MARAD said that drilling has also started at the Lukanani-2 well site, another key location within the Stabroek Block. MARAD said that drilling at this site commenced on June 11, 2025, and is expected to conclude on July 31, 2025. The Stena Carron drillship is also being used at this well, which is situated approximately 110.53 nautical miles (204.39 kilometres) off the coast of Guyana and spans 0.29 square nautical miles (1 square kilometre).
The Lukanani-2 well follows the Lukanani-1 discovery, which was announced in April 2022. Lukanani-1 encountered 115 feet (35 meters) of hydrocarbon-bearing sandstone and was drilled in a water depth of 4,068 feet (1,240 meters). The find contained gas condensate and added to Exxon’s growing list of discoveries in the prolific Stabroek Block.
To date, ExxonMobil has made 46 discoveries in the 6.6-million-acre Stabroek Block. Six projects, namely Liza 1, Liza 2, Payara, Yellowtail, Uaru, and Whiptail, have received regulatory approval for development, and applications have already been submitted for two more projects. Notably, the first three are already producing an average of 650,000 barrels of oil per day (bpd). Production is expected to increase further with the start-up of Yellowtail later this year.
ExxonMobil is also seeking approvals for additional developments at Hammerhead and Longtail, with plans to raise Guyana’s daily oil production capacity to 1.2 million barrels per day by 2027.
