摘要
A system for offshore hydrocarbon electromagnetic prospecting is described. The system includes a transmitter generating electromagnetic energy and injecting an electrical current into a flooded vertical cable. Electromagnetic fields generated by this current in the medium are measured by total field magnetometers or gradiometers. The measured response, which is sensitive to the resistivity of targets, is used to search for and identify hydrocarbon reservoirs. A method for offshore hydrocarbon electromagnetic prospecting is described as well.
