摘要： To provide an exploration system that electromagnetically explores a target structure, including: a magnetic field generation apparatus that generates a magnetic field toward the target structure; and a magnetic field detection apparatus that detects a magnetic field that propagates from the target structure, the propagated magnetic field being generated due to the magnetic field generated by the magnetic field generation apparatus, wherein the magnetic field detection apparatus has a communication part that transmits information of the detected magnetic field to an external device in synchronization with a timing at which the magnetic field generation apparatus generates the magnetic field and a timing at which the generation of the magnetic field is stopped.

摘要： A vertical bipole source in a borehole generates a vertical bipole flow. The vertical bipole flow generates mutually orthogonal time-domain B-field data. Magnetic receivers at a surface location receive the time-domain B-field data and determine elements of a hydrocarbon reservoir using a 3D EM inversion technique. The vertical bipole source may extend into the borehole or be a virtual bipole source located at a surface location above a reservoir.
