CEMENT EVALUATION AND CASING ECCENTRICITY DETECTION WITH CBL IN NON-CONCENTRIC CASING STRING WITH NARROW ANNULUS
Disclosed herein is a workflow for evaluating the cement between a casing string and the surrounding formation in a wellbore and for determining casing string eccentricity using sector cement bond log (CBL) data. This method involved using a cement bond logging tool with an extended acquisition time window to capture multiple interface echoes. From this sector CBL data, a data matrix of waveform information is generated, with each row representing waveform data from different azimuthal sectors. Through singular value decomposition, the principal components of the matrix are identified. Subsequent component analysis emphasizes significant components of waveforms. The significant waveform components are then used to model waveforms using local cluster modeling. The method proceeds by analyzing decomposed data to pinpoint cement zones, compute an eccentricity index for casing deviation, and detect cement channels.
