 UPDATED!  How to Create a New RadExPro Processing Project and Load Input Data

The tutorial is aimed at absolute beginners in RadExPro software who want to quickly get started. It is a basic guideline describing the concept of RadExPro processing projects and giving a step–by–step instruction of how you can create a project and load seismic data into it (which is the very first step in RadExPro before you start any seismic processing).

 UPDATED!  High–Resolution Offshore Mutichannel Seismic Data Processing in the RadExPro Software

The tutorial describes a conventional workflow for high–resolution offshore data processing in RadExPro, including data load, geometry assignment, geometry QC, preprocessing, interactive velocity analysis, stacking, post–stack Kirchhoff migration and printing the results. It can be used as a basic guideline for the real–life processing tasks.

 UPDATED!  Computing Seismic QC Attributes, Fold and Offset Sampling in the RadExPro Software

Here we discuss one of the stages of seismic data QC (either in–field, on boad a ship, or in the office)—computing QC attributes (amplitudes, frequencies, SNR), CMP fold and offset sampling. This is a step–by–step tutorial based on a fragment of an on–shore 3D survey.

 UPDATED!  Creating Seismic Survey Map, Fold and Offset Sampling Maps, Singal–to–Noise Ratio Map in the RadExPro Software (Working with Cross–Plots)

The tutorial is addressed to those who use RadExPro for seismic QC—the process of map generation (including survey map, CMP fold and offset sampling maps, SNR map) is described in detail. The maps are created using the CrossPlot module of the software. The demo project contains a specially prepared 3D dataset: with trace heades only (data was truncated to 1 sample per trace to keep the size reasonable), containg geometry and pre–calculated values of fold, offset sampling and SNR.

Seismic Reflection Data Processing in the RadExPro Software

All standard stages of basic CDP processing are covered, from geometry definition to stacking, that is the so–called minimal processing sequence. Creating of a new RadExPro processing project, data load and assigning geometry, data display and interactive analysis, sorting, preprocessing (amplitude recovery, spectral widening, bandpass filtering, trace equalization, muting), interactive velocity analysis, NMO–correction, stacking and display of the resulting CMP stack are discussed.

VSP Data Processing in the RadExPro Software

The tutorial covers all standard stages of basic VSP processing, from data input to building a velocity model, tying VSP data to seismic survey data and printing out the results. Creation of a new RadExPro Plus processing project, data load, assigning geometry, picking of first arrivals of the P– and S–waves, component orientation, estimation of the deconvolution parameters, reflected wave field separation, building of velocity model, corridor stack trace, VSP migration and VSP–CMP transformation, tying of VSP data to seismics are discussed.

 UPDATED!  Plus-Minus Method of Refraction Seismic Data Analysis in RadExPro Software

The tutorial describes interpretation of seismic refraction data using the Plus-Minus method in the RadExPro Easy Refraction module. All steps are discussed: data loading, geometry assignment using the new intuitive Near–Surface Geometry Input module, first break picking, assigning travel–time segments to different layers and, finally, inversion of the travel times and building a layered velocity model of the subsurface.

 UPDATED!  Multichannel Analysis of Surface Wave (MASW) in the RadExPro Software

The tutorial is addressed to those who want to learn how to process surface wave data in the RadExPro using the MASW method. All processing stages, including the data loading, geometry assignment using our brand–new interactive module, extraction of dispersion curves, joint inversion of the fundamental and higher modes, and building of the resulting Vs cross–section are described.
