Comparison
A StarSteer Alternative for Geosteering Teams
StarSteer is an established geosteering package from ROGII with a deep feature set. GeoMaster is a newer, browser-based platform with public pricing. Here is an honest comparison, using only what ROGII states publicly.
Everything in the StarSteer column is taken from ROGII’s own public description of the product, checked on 1 September 2026: rogii.com/products/starsteer. Where ROGII does not state something, this page says “not stated” rather than “no” — a marketing page cannot prove a product lacks a feature. If anything here is out of date or wrong, tell us and we will correct it.

When StarSteer is the better choice
- →You need stochastic resistivity inversion, which GeoMaster does not do.
- →You want a machine-learning auto-steer capability in production today — GeoEngine is still in development.
- →Your team already runs the ROGII toolchain and your data lives in Solo.
- →You need the depth of a mature product with many years of field use behind it.
When GeoMaster is the better choice
- →You want to see the price before talking to anyone. Every GeoMaster plan and limit is public.
- →You want to start on a free plan and try it on a real well before committing.
- →You want dogleg severity, apparent-to-true dip, TVD and net pay handled across the survey set as standard.
- →You want one browser workspace with no install, for geologists, drillers and client reps at once.
Try it on a real well before you decide
The free plan covers one project with no card required, so you can put GeoMaster on your own data rather than take a comparison table’s word for it.
