Choosing the Best Geosteering Software
Every comparison uses only what the other vendor states publicly, with the source and the date it was checked. Where they do not state something we say so, rather than claiming they lack it, and each page says plainly when the other product is the better choice.
GeoMaster vs StarSteer
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.
Read the comparison →GeoMaster vs ZoneVu
ZoneVu by Ubiterra is a cloud subsurface platform spanning drilling, geosteering and completions. GeoMaster is narrower and focused on geosteering, with public pricing and a free plan. Here is an honest comparison, using only what Ubiterra states publicly.

There is no single best geosteering software for every team. The right choice depends on how you steer, where your data lives, and what you can spend. These are the questions we would ask of any vendor, including us.
Which steering methods does it support?
Model-based steering to a structural or petrophysical model, stratigraphic steering against a type well, or both. Check that correlation, flattening and dip handling work the way your geologists already interpret.
Where does it run?
Desktop software needs installing and licensing per machine. Browser-based geosteering software lets the rig, the office and the client see the same well without VPNs or file transfers.
How does data get in?
LAS import covers offline and post-well work. Live wells need a WITSML connection. Ask which versions are supported today, whether pulls are scheduled or on demand, and what is on a roadmap.
Is the survey mathematics right?
Dogleg severity, TVD and apparent-to-true dip should use the minimum curvature method. You can check any tool against our free calculators.
What does it cost, and can you try it?
Many vendors do not publish prices. Look for a free plan or a trial long enough to steer a real well before you commit.
Where is your data stored?
Ask about data residency, encryption at rest and in transit, and whether your well data is ever used to train models.
