Two smaller study areas within the North area are later studied over a longer monitoring period and include additional drainage...

... in the subsurface, as shown by the formation testing data. Detachment surfaces were interpreted as faults with a highly conductive, low-angle surface on the resistivity image and with high gamma ray log (GR) readings. The natural fracture system in the study area appears to be controlled by the detachment surfaces...
