MOL/XOMs HOD 1 is located in the "donut" in your map.

Mako 7 is a significant well on a huge site with a pipeline connection ,going through all of the known formations.Reentering that well XOM could test any of the formation or drill a new one (HOD 1 new) nearby.

If EXXON wants to walk away or has decided to do so,the decision should be around soon.What´s the use of delaying such a decision for another few month ?
