  • Method for Acquiring and Interpreting Transient Electromagnetic Measurements
    Publication number: 20080183391
    Abstract: A method for interpreting transient electromagnetic survey data includes measuring response of subsurface Earth formations to a plurality of time separated transient electromagnetic fields imparted thereto. An amplitude time decay of a selected one of the measured responses is modeled. An amplitude from the modeled amplitude time decay is added to a one of the measured responses later in time than the selected measured response if the amplitude is less than a selected threshold. The method includes at least one of storing and displaying a result of the adding.

  • Method for acquiring and interpreting transient electromagnetic measurements
    Patent number: 7356411
    Abstract: 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.
