Package Description

This training package provides an in-depth exploration of advanced seismic characterization, specifically focusing on the indirect determination of shear wave velocity in slow formations using full-wave sonic logging techniques. Through a comprehensive set of PDF and video tutorials, the course covers the essential theory and formulations required to correlate the formation’s Poisson’s ratio with the shape of the P-wave packet—a method critical for scenarios where shear wave velocity is lower than the borehole fluid velocity. The curriculum features a rigorous, line-by-line investigation of the specific code types involved, including the FORTRAN source code used to process data via high-pass filtering and peak amplitude analysis, as well as the ABAQUS model designed for finite element simulation of acoustic wave propagation.

By engaging with these specialized workshop materials, users will master the “Indirect determination of shear wave velocity” methodology, learning to identify anomalous Poisson’s ratios and effectively interpret sonic logs that would otherwise be considered unreliable. The training guides learners through the practical application of the P-wave packet shape factor theory, enabling them to execute numerical simulations using ABAQUS/Explicit to validate field data. Ultimately, this course equips engineers and geophysicists with the computational and analytical skills necessary to extend the range of full-wave sonic logging applicability, ensuring accurate velocity profiling in complex geotechnical investigations involving soft or “slow” rock formations.

What will you learn?

Based on the provided text, you will learn a methodology for the indirect determination of shear wave velocity ( $V_S$ ) in “slow” formations where $V_S$ is lower than the fluid velocity, using full-wave sonic logging. The text explains how to correlate the shape of the P-wave packet (specifically its amplitude and duration) with the formation’s Poisson’s ratio to derive accurate velocity profiles. Additionally, you will learn how to implement this approach using finite element simulations (ABAQUS) to establish the correlation and FORTRAN code to process raw sonic log data.

Who is this course for?

This course is designed for geotechnical engineers, civil engineers, and geophysicists involved in seismic characterization projects who need to interpret full-wave sonic logs in challenging “slow” formations. It is also targeted at professionals interested in applying numerical methods (like Finite Element Analysis) and custom programming (FORTRAN) to solve complex wave propagation problems in borehole environments.

Why do I have to pay for this training?

Master a specialized workflow to rescue seismic data in ‘slow formations’ , effectively solving the industry-wide failure of standard semblance processing to distinguish rock shear waves from fluid arrivals. This training bridges the gap between theory and practice, teaching you to execute complex ABAQUS finite element simulations and custom FORTRAN algorithms to correctly derive shear wave velocities.

What do you get by purchasing this package?

By purchasing this package, you will get access to the following:

Training video: To facilitate your learning experience, we provide video tutorials that complement the PDF guide. These videos offer an in-depth explanation of the theory and guide you through each workshop, demonstrating exactly how to analyze the files and interpret the results.
