LLOG lines up three exploration wells in GoM Who Dat area

The Noble Valiant drillship will spud well MC 509-1 after completing its current drilling commitments and mobilizing to the site. The well will target 2C resources of 17 MMboe with an estimated geological probability of success estimated of 62%. 

It should be followed around mid-year by the 31-MMboe Who Dat South exploration well MC 545-1 (LLOG), to be drilled by Seadrill's West Neptune drillship.

Here, the main goal will be to test two intervals in the Miocene section, with the shallower target similar to the reservoir in the field’s G-1 well. If discoveries result, both accumulations would likely be tied into existing infrastructure.

Subject to joint venture approval, the Who Dat West exploration well MC 629 (LLOG) will start drilling in late third-quarter to early fourth-quarter 2024. The total estimated cost of the three-well campaign is in the range $100 million to $120 million.

Production from the field has been impacted of late by delays in bringing the G2 and G4 wells online, lower well productivity than anticipated and bottlenecks in the G-manifold subsea production system.
