Dielectric well logging with radially oriented coils |
| 摘要 |
A dielectric well logging system has its coils aligned radially, rather than in alignment, with respect to the longitudinal axis of a sonde which moves the coils through a borehole. Improved shielding is also provided. The coils have different and improved response characteristics.
