Karoon Energy approved drilling the Who Dat East and Who Dat South wells in the US Gulf of Mexico, with LLOG as the operator.

The drilling cost, estimated at US$67-$77 million ($102.9- $118.2 million) net to Karoon, is part of a joint venture agreement.

Who Dat East aims to delineate a 2001 discovery and test additional targets, holding an estimated 17 MMboe of gross unrisked 2C contingent resources and 35 MMboe of gross unrisked 2U prospective resources, with a 62% probability of success.

This increases Karoon's 2024 capex by US$117-134 million ($179.6-$205.7 million).
