What Exists Beneath the Place Where Conrad Schlumberger Achieved the First (1912) Electrical Prospection Experiment

The first experimental demonstration of the voltage distribution at ground surface achieved by C. Schlumberger in 1912 was in fact located over the remains of the ancient Val Richer Cistercian abbey. The electrical survey of these remains allowed the location of the ancient church and cloister. It also permitted the deeper ground resistivity to be known thus a better understanding of the 1912 results.
