  • 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.

  • METHOD FOR CORRECTING MAGNETIC BASED ORIENTATION MEASUREMENTS FOR LOCAL BIASING FIELDS
    Publication number: 20090128138
    Abstract: A method of determining an orientation of a data acquisition system deployed on a seafloor includes measuring horizontal magnetic fields using detectors on the data acquisition system while the data acquisition rotates and descends to the seafloor or rises from the seafloor. Resting horizontal magnetic fields are measured after the data acquisition system is on the seafloor. A heading of the data acquisition system on the seafloor may be determined based on maximum and minimum horizontal magnetic fields measured during the descent and the resting horizontal magnetic fields.
