Sorry, but I can see that this is the bottom of the core we took and to me it looks like a fairly tight sandstone but am no Geo so prefer others with more actual experience to take a stab at waht if any sifnificance this sample demonstrates..I mean they wouldn't show it if it was non-porous tightly bound sstone would they...
Is that a fracture going from middle to left at 2807.4??
