Abstract
In general, optimal DC Resistivity measurements are made on the line perpendicular to the direction of the anomaly. However, sometimes topographical and environmental constraints can led to non ideal condition and measurements are carried out parallel to the anomaly direction. Interpretation of optimal results for these non-ideal conditions requires modeling in order to see the response of the resulting measurements. This paper discuss the finite difference-based 2D DC resistivity responses modeling for the anomaly parallel to the line of acquisition. Variations in anomaly and host resistivity values, distance between electrodes and Wenner and Schlumberger measurement configurations are used to observe the measurement responses from different conditions.
