ANT #4 elevation

[Getitrt2]

If you compare the reservoir volumes in the 2D maps with contour lines using trigonometry Getit, the western side of the new reservoir map has less volume. I think pet saw that and pointed it out.

I am well aware of how that works and that a lower A5 would mean lower volume, without your explaining it to me.  Did you use the trigonometry to calculate new volumes?!  I think Pet also said A6 is also indicated to be higher than A4 and that it appears "they might have moved the western boundary of the field to the west", as I said before, which could provide some offsetting increases to volumes.  Your trigonometry would apply to those also.
