🎉Two New Courses on Res2DInv!🎉
Hello Seequent Community! We’re excited to announce not one, but two brand-new Res2DInv courses now on the Seequent Learning Centre! 📘 AGS | Geophysical Inversion Theory in Res2DInv If you’ve ever wondered why Res2DInv behaves the way it does, this course is for you. It covers the geophysical concepts that power the…
Beyond 1D: Smarter TDEM Inversion for Complex Geology
Why do some inversion results look nothing like the geology you expect? We recently shared some thoughts around this topic as a conference. We discussed practical strategies for tackling this challenge using advanced TDEM techniques. ✅ What we explored: Working with TDEM data to map conductive bodies Comparing inversion…
How to show shapefile labels on a map in Geosoft Oasis montaj?
Hello everyone, I’m currently working on a mineral exploration project using magnetic data in Oasis montaj. I’ve added a shapefile containing mineral index locations within my study area, but I’m not sure how to display the labels (i.e., the mineral index types) on the map. Could anyone please guide me through the steps to…
How to get a defined boundaries of a masked grid?
Hello everyone, I masked my grid using a polygon to only include my area of interest, AOI (within the polygon). However, the grid boundaries are not well-defined. My polygon is rectangular but the masked grid has irregular or 'zigzag' outer boundaries. Is there a way to get these boundaries clear (shaped as rectangle…
Removal of Line Artifacts
Hello everyone, My gravity data has been previously levelled but I observe noises that could be line artifacts since they seem to be following the survey lines. I don't have the line levelling extension to use. Based on several references, this could be improved by applying directional cosine filter. However, the filter…
New Community Champion - Jack Chanmala - Geophysics
Hey everyone, My name is Jack Chanmala, and I’m excited to join this community! I’ve spent my career in exploration geophysics and mining, working across the spectrum—from junior exploration companies running drill rigs to major mining operations like Rio Tinto, where I focused on iron ore projects. Over the years, I’ve…
Null Data Affects the Grid?
Hi everyone, Some columns in my dataset have null values of 999999.99. I am trying to grid these columns, and they look odd. The 'background' where no acquisition lines are available, appear in single color. While the areas with lines are shaded in a different color. Could the null values be the culprit of this issue? If…
Residual-Regional Separation (FTG)
Hi all, a new learner here. I am working on FTG data on Oasis montaj and still familiarizing myself with the geophysics workflow. I want to separate the residual-regional anomalies of the FTG data. This can be done by wavelength filtering, right? However, I am confused on how to decide the cut-off wavelength for filtering.…
Ground Gravity Deliverable Standards
Is anyone aware of a document that defines standards for deliverables on a modern gravity survey? Most archives I have received include both the instrument dump files and a database or spreadsheet containing the final data including the primary location and gravity data, the corrections applied on the meter (if…

With a background in geophysics and hands-on experience using Oasis Montaj, I’m here to help professionals like you get the most out of our software. Whether it’s troubleshooting, best…
Problemas con el 3D del Res2Dinv
Hola a todos Tengo un problema al representar las tomografías en la sección 3D. El caso es que salen en coordenadas geográficas decimales y no reconoce ese formato, por lo que se tiene que poner la coordenada del primer punto a mano. El problema es que no encuentro la manera de girarla, ya que sale en orientación N-S.…
Constraining geological model with uncertain geophysical data
I have geophysical data which i want to use to constrain model developed with drill hole data. In some areas, the quality of the geophysical data is poor at shallow depth. Is there a way to condition Leapfrog to "down-weight" data for this region while still using the entire data?
Map so slow
Don’t know what happens but when I add any layer to my map always need to refresh it(refresh means zoom in or out) before It is displayed or removed
2D SEG-Y Elevation Issue
Using the new Geophysics module in Leapfrog Geo I've been trying to import some 2D SEG-Y files that I have downloaded from SARIG (line 86AK-7) The profiles plot in the correct XY location however they plot well below the topographic surface. I've played around with different import parameters but the best I can get is…
