Electromagnetic method and apparatus for determining the nature of subterranean reservoirs using refracted electromagnetic waves |
摘要 |
A method for investigating subterranean strata. An electromagnetic field is applied using a dipole antenna transmitter and this is detected using a dipole antenna receiver. Phase information is extracted from a refracted wave response and used to identify the presence and/or nature of a subterranean reservoir.
