Model 2552 -Flow Sensor

The formations surrounding the well are subjected to an alternating square wave voltage applied through the upper and lower injection electrodes. After each injection cycle, the resulting potential difference in a section of the formations is analyzed as it decays over time. The shape of this decay curve is related to the “chargeability” of the formations. A high load capacity indicates that the induced electro-chemical potentials can develop within the formations as a result of ion transfer between the pore fluids and the semiconductor metallic mineral grains present within the rocks.
