    摘要： Methods and related systems are described for analyzing electromagnetic survey data. Electromagnetic survey data of a subterranean formation is obtained using at least a downhole transceiver deployed in a borehole and a transceiver positioned on the surface, or in the same or another borehole. Limits are defined for casing correction coefficients that account for effects of the borehole casing. A constrained inversion process is performed solving for the casing correction coefficients within the defined limits, and for one or more parameters of a model representing attributes, such as resistivity, of the subterranean formation.

    摘要： To perform a marine survey of a subterranean structure, a vertically oriented electromagnetic (EM) source is positioned in a body of water, where the EM source is coincident with an EM receiver. The EM source is activated to cause transmission of EM energy into the subterranean structure. After deactivation of the EM source, an EM field affected by the subterranean structure is measured by the EM receiver. In an alternative implementation, a survey system is provided that has a continuous wave EM source, a main EM receiver, and an auxiliary EM receiver.

    摘要： A towed marine source to borehole electromagnetic survey system and method for surveying employing the same is disclosed. The system includes a sea vessel adapted for traversal of sea water over a subsea formation, a power supply affixed to the sea vessel and a high moment loop source coupled to the power supply, and a signal generator by a tow cable; said signal generator being affixed to the sea vessel configured to control operating parameters of the high moment loop source. The system also includes a wellbore drilled in the subsea formation, a series of electromagnetic (EM) receivers positioned in the wellbore. Each receiver includes a sensor module having sensing elements to measure one or more of electric fields, electric currents, and magnetic fields produced by the high moment loop source when towed by the sea vessel, and a storage device configured to store data from measurements made by the sensor module. The system further includes a computer processor configured to receive stored data from the receivers and analyze the stored measurement data to determine a location of an electrically resistive formation anomaly at a depth of between 1 to 5 km.
