Public releases show the prospect to be heavily faulted with complex structuring. This is a good style of prospect to apply 3D to image the faults and help map them.

Sometimes large prospects are mapped and drilled on 2D - and if hydrocarbon bearing then the company 3Ds. But more and more companies 3D if the cost is 1/4 - 1/2 times the cost of the well.

Time to record a marine 3D is heavily dependent on the tides and wind state (do know the weather patterns but in a straight the tides would be significant) but all but biggest ones are weeks not months.
