Resistivity measurement through metal casing using magnetic field and magnetoacoustic phenomena |
摘要 |
Measurements of acoustic velocities are made through a case borehole in the absence and presence of an applied magnetic field. A formation resistivity parameter may be estimated from differences in the acoustic velocities.
