2D Model Study of CO₂ Plumes in Saline Reservoirs by Borehole Resistivity Tomography

Figure 2

Tripotential electrode configurations α and β applied for electric resistivity tomography in boreholes (inhole and crosshole) using 4-pole of current (C) and potential (P) electrode pairs. The survey can be conducted in circulating (c) vertical, v (a), lateral, l and horizontal, h (b) modes and tripole-pole, tp-p (c) which is a special type of circulating vertical configuration with fixed C electrodes [24].
