Abstract: A method for mapping sub-surface resistivity contrasts comprising making multi-channel transient electromagnetic (MTEM) measurements using at least one electric source with grounded input current electrodes or one magnetic source with current in a wire loop or multi loop and at least one electric field or magnetic field receiver, measuring the resultant earth response simultaneously at each receiver using a known recording system, measuring the system response by measuring directly the current in the wire at the source using effectively the same recording system, using the measured system response to recover the impulse response of the earth from each measured earth response, and creating from such impulse responses a sub-surface representation of resistivity contrasts.

Abstract: A method for removing cultural noise from a measurement of the field generated by an electromagnetic source, such as a current bi-pole or a magnetic loop source, the method comprising: simultaneously measuring the electromagnetic signal at a field measurement position and a calibration position close to the field measurement position, but in a null field of the source; using the field measurement and the calibration measurement to compute a filter that estimates the component of the field measurement that is correlated with cultural noise; convolving the computed filter with the calibration measurement to yield the estimated cultural noise component, and subtracting that component from the field measurement.

Abstract: A method for estimating the effects of an airwave in marine electromagnetic data measured using a source and at least one receiver. The method involves measuring the electromagnetic response at two different under water source-receiver separations and using measurements at the larger separation to estimate the airwave response at that separation. The airwave effect in the response measured at the shorter separation can then be determined using the estimated airwave response at the larger separation.
