This was my first research report for my Master’s degree in 1999 (DEA: Diplôme d’Etudes Approfondies), almost 25 years ago. This was the first time a numerical model was publicly presented to the Master’s jury. Based on seismic stratigraphy, we…
The main aim will be to export nav file from the seismic software (here we use kingdom) and to import it in QGIS. You could also have nav files in ASCII format (i.e. txt files: start where *** are displayed).…
You find an interesting map, for instance in an article and you want to import it in your QGIS project. The main aim will be to redraw some features (points, lines) that you need in your study (creating a structural…
Using QGIS is essential in starting a project as it will concentrate all spatial data needed for displaying or exporting in other softwares such as Kingdom or Petrel. First, you must download the latest stable version here: https://www.qgis.org/en/site/index.html QGIS has…
Loading well data can be a nightmare. The very important thing is to check whether the window is displayed in time (TWT). Have a look at the top of the window and select either TWT or TVD (in meters) or…
Interpreting faults in seismic data leads to numerous mistakes (or misunderstanding). The most important thing is: In seismic softwares, a fault = one fault plane ! It has consequences on how to manage large collections of faults. It means that…
ndSerf is a freely available application for the visualisation and analysis of surfaces. Applications include visualisation of landscapes; geomorphological analysis; gaming; GIS file conversion; map output; archaeological mapping and analysis; surface modelling and many others. It runs on any platform…
Picking horizons is one of the most useful things to do for interpreting seismic data in sedimentary basins. Please find below some tricks based on a very long experience in seismic interpretation using Petrel: In general: Right click on “interpretation…
Please find below some usefull links. The list will be updated on a regular basis. > Youtube links: Some basics in Petrel How to load checkshots and define formation tops in Petrel How to load 2D seismic with nav files:…
Loading seismic is a real challenge as geophysicists use their own way to store data in segy files 🙁 They are supposed to write parameters in headers. However, due to various actions (copying files, folders, exporting seismic profiles from third…
