Three Heavyweights in the Deep
Three companies sit right at the nexus of this development.
First, you have ExxonMobil. With a market capitalisation north of $640 billion, they are the undisputed apex predator here. They sign the cheques and drive the project forward.
Then you have Schlumberger. ExxonMobil might own the rights, but they need Schlumberger's subsea robotics and well construction technology to actually get the gas out of the seabed.
Finally, there is Hess Corporation. Hess holds a direct partnership stake in the block. They are a smaller player, but their fortunes are heavily tied to this specific patch of water.
Hess is arguably the purest play, but pure plays always carry a sharper edge.
