Uncompensated electromagnetic wave resistivity tool for bed boundary detection and invasion profiling |
摘要 |
<p>A resistivity tool and associated method include measuring the phase shift of an electromagnetic signal at different locations. Preferably, this is accomplished by a resistivity tool having three receivers. The difference of the phase shifts at the different locations indicates with precision the depth in a borehole of a bed boundary. The preferred resistivity tool also yields improved radial resolution.</p> |
