  • Methods and systems for using a combined electromagnetic source electrode and deflector
    Patent number: 9664811
    Abstract: Disclosed are methods and systems for marine geophysical surveying that include a combined electromagnetic source electrode and deflector. An example embodiment discloses an electromagnetic source assembly comprising: a deflector-source electrode, wherein the deflector-source electrode comprises an electromagnetic source electrode integrated into a deflector; a separate electromagnetic source electrode; and a power source coupled to the electromagnetic source electrode and the separate electromagnetic source electrode.
    Type: Grant
    Filed: December 19, 2012
    Date of Patent: May 30, 2017
    Assignee: PGS Geophysical AS
    Inventors: Johnathan P. Linfoot, Oliver Colin Peppe
  • Stationary source for marine electromagnetic surveying
    Patent number: 9239401
    Abstract: Disclosed are methods and systems for using electromagnetic sources that are substantially stationary in a body of water while electromagnetic field signals are detected with electromagnetic sensors towed through the body of water. An embodiment discloses an apparatus comprising: a vessel; a first electromagnetic source coupled to the vessel and configured to have a dipole moment oriented in a first direction; and a second electromagnetic source coupled to the vessel and configured to have a dipole moment oriented in a second direction, wherein the second direction is generally orthogonal to the first direction. Another embodiment discloses a system comprising: a sensor streamer configured for towing in a body of water, wherein the sensor streamer comprises a plurality of electromagnetic sensors disposed at spaced apart positions; and an electromagnetic source assembly configured for deployment at a substantially stationary position in the body of water.
