LLOG-led joint venture to begin drilling $77 million exploration wells offshore U.S. Gulf of Mexico
(WO) – The Who Dat East and Who Dat South Joint Ventures have approved the drilling of the Who Dat East appraisal/exploration well and the Who Dat South exploration well offshore the U.S. Gulf of Mexico. The total cost of the two wells is expected to be $67-77 million.
Who Dat East. Who Dat East lies approximately 27 km east of the Who Dat Floating Production System (FPS). The Who Dat East well, MC 509-1 (LLOG), is expected to spud in the first half of April 2024, using the Noble Valiant drill ship. The aim of the well is to delineate a discovery made in 2001, and test additional targets in the Middle Miocene section.
The well is designed to test five main reservoir intervals and may be suspended as a potential future producer. Who Dat East is estimated to contain 17 MMboe of gross unrisked 2C Contingent Resources (5.4 MMboe net to Karoo) and 35 MMboe of gross unrisked 2U Prospective Resources (10.7 MMboe net to Karoon), with an aggregate geological probability of success estimated to be 62% .
The well will be drilled as a deviated hole with a total measured depth of approximately 7,925 m and will take approximately 56 days to drill and evaluate.
The Who Dat East JV participants are LLOG (operator, 40%), Karoon (40%) and Westlawn (20%).
Who Dat South. The Who Dat South prospect is located approximately 11 km southwest of the Who Dat FPS. The Who Dat South exploration well, MC 545-1 (LLOG), is expected to spud towards the end of the second quarter of CY24, using the Seadrill West Neptune drill ship.
The objective of the well is to test two targets in the Miocene section, with the shallower target being similar to the reservoir in the G-1 well in Who Dat. The Who Dat South prospect is estimated to contain 31 MMboe of gross unrisked 2U Prospective Resources (7.6 MMboe net to Karoon on a NRI basis), with the geological probability of success estimated to be 52%.
The well will be drilled as a deviated hole with a total measured depth of approximately 7,425 m. It is expected to take approximately 50 days to drill and evaluate.
The Who Dat South JV participants are LLOG (operator, 40%), Karoon (30%) and Westlawn (30%).
