摘要： Hybrid inversion processing techniques are implemented that result in improved speed and accuracy of determining formation properties using log data, for example, from an multi- component induction logging tool. Logging data relating to the formation of interest is obtained and used as an input. High frequency noise is then removed from the logging data and bed- boundary determination is performed using the logging data. An adaptive low pass filter is applied to the logging data and the logging data is inverted. The inverted logging data is correct and enhanced by determining one or more weights based on one or more quality indicators. The inverted logging data may then be visually interpreted and used to adjust one or more drilling parameters.

摘要： Hybrid frequency/time-domain modeling may be used to compute the synthetic transient response to an eddy]current pulse for use in a high]dynamic]range and efficient inversion method for pulsed]eddy]current pipe inspection tools. In accordance with some embodiments, frequency]domain response signals are computed for a plurality of frequencies and converted, by frequency]to]time]domain transformation, to a first synthetic transient response signal. A time boundary associated with an onset of spurious oscillations in the first synthetic transient response signal is then automatically determined, and a second synthetic transient response signal beginning at the determined time boundary is determined directly with a time]domain numerical technique. A portion of the first synthetic transient response signal ending at the time boundary may be combined with the second synthetic transient response signal.

摘要： A calibration system for an electromagnetic (EM) tool includes a processor. The processor employs the EM tool to measure responses at each of a plurality of channels. The processor records the measured responses at each of the channels in an EM data log for the channel. The processor determines a nominal value of each of the channels, as being equal to a histogram peak of the EM data log. The processor selects one or more calibration points from the EM data log for a particular channel, based on a difference between the nominal value of the particular channel and the measured response at the calibration point being greater than a particular threshold. The processor determines a plurality of parameters by reducing a misfit between synthetic data and both the nominal values of the channels and the measured responses of the channels at the selected one or more calibration points.
