Abstract The producing basins located in Los Andes region of Colombia are often subject to active tectonic stresses and severe faulting. This is exacerbated by uneven formation pressure due to preferential depletion or injection. Due to the large horizontal stresses, the casing often deforms plastically, resulting in buckling, shearing and ovalization. Consequently, the ability to re-entry the well may be compromised, the production can be impacted, and the mechanical properties of the tubulars can also be affected. The well presented in this study was evaluated using Multifinger Caliper, Electromagnetic thickness measurements and Segmented cement tools. The presence of casing deformation is sometimes masked by the processing steps involved in the data conditioning of the internal radius measurements. Multifinger caliper data automatically corrected for eccentricity does not show obvious signs of deformation, although the pipe tortuosity can be severe. In this well, different deformation mechanisms are identified, and a procedure is proposed to characterize the type and magnitude of these events. Apart from corrosion and internal casing wear, the remnant mechanical properties of the pipe are also impacted by deformation and might result in reduced burst and collapse ratings. Electromagnetic thickness data is used to evaluate this aspect. Integrating the multifinger caliper results with the cement evaluation logs show that the main deformed intervals lack of annular cement isolation. This was key to understanding the nature of the faults, that not only contribute to well deformation, but are also conductive pathways that lead to fluid and cement losses. Correlating the deformed intervals and sections with poor cement with the geological descriptions of the field allows identifying, and sometimes predicting, problematic faults and potential high-stress regions of the formation. This has an immediate impact on the field development plans, well design and surveillance programs. Moreover, by establishing a clear workflow to identify and characterize deformation through internal radius evaluation (multifinger caliper or ultrasonic logs), the analysts are better equipped to face similar situations in future evaluation jobs, and also capable to re-analyze existing logs in the field. This study highlights the value of data integration in cased hole logging integrity evaluation. The combination of the casing integrity and cement logs leads to a deeper understanding of the fields' faulting and stresses, which allows identifying wells that require interventions and integrity evaluation, and is vital information for the management of the reservoir and future well placing.
