As I said, I know nothing about it but only speculated about a possible cavern size. If, instead, it's big sponge, then, like other depleted reservoirs (sponges)we needn't worry about them collapsing, right? Well, not exactly. When the incompressible liquid is removed from the reservoir rocks they may collapse a bit as the porosity goes to zero. There has been subsidence observed in Long Beach and the sea floor of North Sea and other places, but as far as I know these have all been shallow reservoirs and it occurred over a long time. I can't imagine how subsidence could be a problem at Macombo at this point in time. Best, JRH
