Figure 2. Raw logs and inversion results for the interval, 470-500 m, Well E-1 from Australia. Results of 2-D inversion are shown in tracks 3 and 4. The data fit between measured and synthetic HDLL first differences and the absolute voltage V4 are shown in tracks 5 and 6, respectively. The 2-D inversion results and field SFR curves calculated using recorded (offset) voltage V4S are presented in track 7. The corrected SFR curves calculated with application of the synthetic V4 log are shown in track 8.
