Techlog Acoustics Processing and Interpretation

This course teaches the theory, processing and interpretation of sonic waveforms using Techlog platform. Participants will learn how to QC raw data such as waveforms, and slowness projections. Participant will also learn how to perform field data slownesses relabeling and process acoustic data for formation slownesses and anisotropy. Also, dispersion analysis tools will be explained in detail to allow users to define the most appropriate parameters for their processing.

Furthermore, Slowness processing based on Slowness Time Coherence (STC) technique is covered in detail. Acoustic anisotropy using cross-dipole data is covered from the theory, acquisition, to the final processing of acoustic anisotropy results.

This course includes practical exercises to enhance the learnig experience.
