1. A method for processing formation tester data, comprising:

  • obtaining the formation tester data, wherein the formation tester data are time domain data acquired with a formation tester in a wellbore;

    transforming, using a wavelet transform, the formation tester data into a second domain other than the time domain to produce transformed data;

    identifying distortions in the transformed data by analyzing a distribution of wavelet coefficients;

    removing the distortions from the transformed data to produce de-noised data; and

    transforming the de-noised data from the second domain back to the time domain to produce cleaned-up formation tester data.
