This directory contains the seven observed wells.
The well observations are transformed in to a (3D) simulation box
of size [0,2000]x[0,5800]x[0,15].
The format of the well files is
X_1 Y_1 Z_1 facies_1
.
.
.
X_n Y_n Z_n facies_n

Facies_i is the observed rock type in the reservoir (corresponds
to colour in the marked point process) between position (X_i,Y_i,Z_i)
and (X_{i+1},Y_{i+1},Z_{i+1}).
