OBM SENSOR WITH A SINGLE LOOP ANTENNA |
| 摘要 |
<p>A method and apparatus for downhole resistivity imaging uses an antenna coupled to a power source through a directional coupler. Measured reflectivity values are indicative of the antenna impedance and the formation resistivity, particularly if some compensation is made for the antenna inductance.</p> |
