The fields cross. They dont want an Iraq Kuwait situation. Maybe Oilsearch wants to drill a lot in that area and IOC is not interested in that geography right now. So with OS wanting to move forward and IOC not so motivated, OS flipped the tab. Less fighting over who owns what, if a structure traverses both leases.
I've often wondered about what happens if a field goes across field boundaries that are under license holdings of different operators. Is it first come first served I'm sure that IOC's many fields will be shared possibly with Total as they surround IOC acerage. Please enlighten me on this "problem". tyia ed
