Sorry list, I had the list moderated until I was sure that messages would be

John;
When I did similar work in the US we used perforated casing that was
available from the people the do irrigation in the farms. The holes were
about 3 cm in dia and every 10 to 15 cm apart. The relationship with
Resistivity was felt to be related to the size of the array with respect the
separation of the holes. We were using a pole-dipole array the was several
times the separation, so it looked OK.
Good Luck!
