METHODS AND APPARATUSES FOR FORMATION TESTER DATA PROCESSING

摘要

A method for data processing (250) includes transforming measurement data acquired in the time domain during an oilfield operation into a second domain to produce transformed data (251); identifying distortions in the transformed data (252); removing the distortions from the transformed data (252); and transforming back from the second domain to the time domain to produce cleaned-up data. The transforming measurement data may use a Fourier transform or a wavelet transform. The method may further include compressing the cleaned-up data (253) or reconstructing signals from the cleaned-up data (254). A method for data processing includes decomposing measurement data, which are acquired in an oilfield operation, using a low pass filter to produce a first dataset; decomposing the measurement data using a high pass filter to produce a second dataset; removing distortions from the second' dataset to yield a corrected second dataset; and reconstructing a corrected dataset from the first dataset and the corrected second dataset.
