What is

GEOPHYSICS source-code archive

Follow this link to a collection of source codes that accompany articles in the journal GEOPHYSICS.

Public 2D datasets

Follow this link to a collection of public datasets of exploration-geophysical interest available for free download. The same datasets are also available from the SEG website, their original home, but that way of downloading them is less preferred now. Note, the datasets have legal disclaimers and requirements attached. Before downloading datasets, first download their associated README files and agree with the restrictions you find there.

  • CWP/SU Seismic Un*x Home Page (A free seismic processing system that uses an expanded SEGY-like data format.)
  • OpendTect (A free open-source seismic interpretation system. The core of the system is available under a GPL license. It is extendable with plugins, some of which require a commercial license.)
  • qiWorkbench (A processing environment originally from BHP Billiton that includes the bhpViewer as one component.)
  • Software from the Stanford Exploration Project (SEPlib, a data-cube-based seismic processing system, along with other miscellaneous software.)
  • The GeoCraft home page (A ConocoPhillips-heritage processing system designed to be a lightweight framework for rapidly prototyping and deploying new geoscience algorithms.)
  • The FreeUSP home page (An Amoco/BP-heritage processing system that uses an expanded SEGY-like data format.)
  • The Data Dictionary System (DDS) home page (An Amoco/BP-heritage processing system supporting high-dimensional flexible-format data files.)
