Zadig,
Permiability while at the most simplistic is inversley correlated with depth it does not always hold true. For example the October 2006 report on Fols 1 well shows that the lowest seams did not have the lowest number and only one seam had .1mD measurement.

The other important aspect with permiability is that the Fols 2 well was designed to exploit directional fractures which will increase the relative porosity of the coals. As to what extent Fols 2 will hopefully show this.

The information about the pump casing being too big came directly from two directors of the company. I know it is hard to believe that such a simple mistake could be made but it can.
