Red, go to post 125248 and on the link of the 3D seismic go to page 2. There are 2 graphs on that page and the second one shows a "Timeslice" graph. Strangest graph I have seen of the area and repeated requests to eoim to evaluate went unanswered. Is this the type of graph you are describing re: 4D? Again, if anyone on the board has the expertise to decipher the graph it would be appreciated.
