  • SURVEYING USING VERTICAL ELECTROMAGNETIC SOURCES THAT ARE TOWED ALONG WITH SURVEY RECEIVERS
    Publication number: 20100013485
    Abstract: A system to perform a marine subterranean survey includes at least one vertical electromagnetic (EM) source and at least one EM receiver to measure a response of a subterranean structure that is responsive to EM signals produced by the vertical EM source. At least one tow cable is used to tow the EM source and EM receiver through a body of water.

  • Prospecting system using rotating superconducting electromagnetic dipole
    Patent number: 4165480
    Abstract: A prospecting system uses a rotating superconducting electromagnetic source which is swept over a frequency range with a magnetometer type receiver sensing the induced field. The effective dipole is rotated in a horizontal plane parallel to the ground surface with the sensed induced magnetic field being in the vertical axis.
