摘要： A method of testing the electric field recording of a marine electromagnetic sensor cable including electrodes is provided. The method includes causing time varying current to flow between at least one pair of current electrodes disposed along the marine electromagnetic sensor cable. The flow of current generates a voltage in a body of water, thereby causing a secondary field impressed on a pair of sensor electrodes disposed along the marine electromagnetic sensor cable. A potential difference between the pair of sensor electrodes is measured. Accuracy of the electric field recording is inferred from the measured potential difference.

摘要： A method for interpreting transient electromagnetic survey data includes measuring transient response of a medium over a plurality of switching events. The measured transient response to a first one of the current switching events is modeled. Transient response to the model for at least one current switching event prior in time to the at least a first current switching event is calculated. The calculated transient response is summed with the first event measured response and the sum is compared to the electromagnetic survey measurements. The model is adjusted and the calculating summed transient responses is repeated until a difference between the summed calculated responses and the survey measurements falls below a selected threshold.

摘要： A method for determining spatial distribution of properties of the Earth's subsurface includes obtaining seismic data over a survey area of the Earth's subsurface. Controlled source electromagnetic survey data are obtained over substantially the same survey area. An initial model of the Earth's subsurface for each of the seismic data and the electromagnetic data is generated. Further data may include gravity, magnetics, seismics any type and borehole data. Each model is optimized on at least one model parameter. Consistency is determined between the models; and the at least one model parameter is adjusted and the optimizing and determining consistency are repeated until the models are consistent. Constraints are successively derived from the data sets and also cross checked against reservoir data where available.
