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

Figure 6

Effect of aspect ratios, AR (first row) on ERT tomograms, resulting from wedge-like CO2 plume scenario W42 (Figure 3, second row) with 30 Ωm plume resistivity for 4-pole configurations βhtp, αβvcs and opt (see Figure 2 and Table 3 for symbols) between two borehole electrode arrays (●). All models show root mean square errors of less than 1%. Solid lines refer to target boundaries.
