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).
NEW! Diffraction Imaging
This tutorial describes a diffraction imaging workflow in RadExPro. It explains the diffraction separation, the migration of diffractions, as well as the N-th root wavefield computation for the detection of weak diffracted events, and the computation of diffraction energy and semblance attributes. These attributes can then be used to detect and analyze the small subsurface heterogeneities which cause the diffractions.
PLEASE NOTE: This tutorial is intended for RadExPro Professional/Real-Time version 2023.4 to be released at the end of December 2023.
Python Proxy – How to Introduce Your Own Algorithms in Python into RadExPro Software
This tutorial is for those who aim to expand the functionality of RadExPro by introducing their own algorithms in Python via the Python Proxy module. The tutorial contains several example implementations of seismic processing algorithms in Python Proxy, including automatic gain control, deghosting, semblance attribute computation and geophone-to-DAS conversion.
The tutorial assumes that you are familiar with the fundamentals of Python processing language. Before starting the tutorial, it is recommended that you read the section related to the Python Proxy in the RadExPro manual. Note that for Python Proxy to function correctly it is preferred that you install Python on your system before installing RadExPro .
The tutorial is accompanied by a project where each of the presented algorithms can be tested on seismic data
NEW! Advanced Offshore High-Resolution Multichannel Seismic Processing
The input dataset for this tutorial was supplied by Applied Acoustics (L200 sparker, 48 channel streamer).
Basic Processing of High–Resolution Offshore Multichannel Seismic Data
The tutorial describes a conventional basic 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.
NEW! Land Seismic QC Attributes: Computation, Mapping and Interactive Analysis
Here we demonstrate how to compute typical land seismic QC attributes (amplitude, frequency, signal-to-noise ratio) in RadExPro software. The second part of the tutorial is dedicated to interactive analysis of the attribute maps using Interactive QC module.
Using CrossPlot Module for Attribute Mapping
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.
NEW! Processing of Near-Surface Land Reflection Seismic Data in RadExPro
In this tutorial, we demonstrate how a novice user can process data of near-surface seismic reflection (CDP) survey using RadExPro software. We will pass through all standard stages of the basic CDP data processing, from geometry input until stacking and time-to-depth conversion, the so-called minimum processing graph. As an example, we use a seismic reflection SH-wave profile. If your data in on P-waves, you can use the same processing graph, just skip the ‘Subtraction of “left” and “right” shots’ part of this tutorial. We assume that the user is already familiar with the theory of the CDP method and the basic technology of the reflection seismic processing.
NEW! DAS Walkaway VSP Processing
This tutorial is for the users who aim to apply RadExPro for the processing of walkaway vertical seismic profile (VSP) data acquired with distributed acoustic sensors (DAS). The processing flows in the tutorial project contain typical walkaway VSP processing procedures, such as correlation with sweep, geometry setup, noise removal, deconvolution, wavefield separation and migration.
The input dataset is a walkaway VSP survey with both DAS and geophones published as an open-source dataset at Research Data Australia. This dataset was provided under a CC BY 4.0 license. More details can be found at https://creativecommons.org/licenses/by/4.0/.
UPDATED! VSP Data Processing
The tutorial covers all standard stages of basic zero-offset and offset 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 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.
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.
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.
