We are pleased to announce the 2019 RING Meeting to be held in Nancy on Sept, 10-13.

Join us to celebrate the 30th anniversary of the RING-Gocad Consortium, learn and exchange about research for integrative numerical geology!

Please use the meeting web page to access more information (call for papers, registration, logistics). We look forward to meeting you in Nancy!




SIGMA is a research library developed by the RING team.The version uploaded for this training has programs for acoustic modeling, extended imaging, and structural interpolation.

In this tutorial, Part I

  • Seismic modeling
  • Seismic imaging

In this tutorial, Part II

  • Finite difference structural interpolation

The RING team wishes you a merry holiday season, and a happy and peaceful year 2018 !

RING's (salt) Chrismas Tree. Happy Holiday Season!

This RING Christmas Tree was generated with SKUA-GOCAD using the stochastic method of Nicolas Clausolles, see Nicolas's IAMG 2018 award on salt modeling.
