Title: (DA) Improved CSEM Survey Method
Abstract:
(DA) There is disciosed a method of performing a controlled source electromagnetic survey, which inciudes in one embodiment deploying a receiver and an electric dipole source. The source defines a dipole axis. An electromagnetic field is transmitted from the electric dipole source. First and second horizontal components of an electromagnetic field response are detected using the receiver. A vertical component of the electromagnetic field response is then estimated using the detected first and second horizontal components of the electromagnetic field response.
