The short version

  • Each has a real cost: 3DEC pricing is not published; licences are quoted, with subscription and perpetual options; IHS Markit Petra iHS Markit Petra's product page (ihsmarkit.com/products/petra.html) now redirects live to spglobal.com, confirming IHS Markit's merger into S&P Global means the Petra product line is sold under S&P Global rather than as an independent IHS Markit product (redirect observed 19 August 2026).
  • They diverge on capability: 3DEC covers 3D distinct element analysis, IHS Markit Petra covers Well log analysis.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

3DEC

  • Pricing is not published; licences are quoted, with subscription and perpetual options
  • A specialist geomechanical tool rather than general purpose simulation, so it assumes the user is a rock mechanics engineer

IHS Markit Petra

  • IHS Markit Petra's product page (ihsmarkit.com/products/petra.html) now redirects live to spglobal.com, confirming IHS Markit's merger into S&P Global means the Petra product line is sold under S&P Global rather than as an independent IHS Markit product (redirect observed 19 August 2026).
