Gravity Structural Inversion for Salt Body?
Dear community, I am a newbie in setting up 3D models for gravity inversion and forward modelling and need your advice on how to structurally inverted for the top of salt surface w/o using VALEM? (1) The input surfaces I use for structural Inversion are very conceptual as I do not have seismic data to further constrain…

Standalone python script to read gdb to numpy array
Hi, a simple processing task I'd like to share with my work colleagues requires reading a gdb to a numpy array. I need this simple script to standalone without the need for a licence key. I also understand that there is an external API with low-level functions for just this task. Can anyone give me some instructions on how…

Datamine to geosoft voxel problems
Problem: Oasis crashes during import of 6GB Datamine file, when attempting to convert it to Geosoft voxel models. Tried this on OM 6.4, then on 8.4 with pretty much similar results. Is it due to RAM issue (I checked OM instances are only using about 160 Mb out of my 16GB RAM). Have anyone encountered similar issues before?…

Strip log Parameters
Currently total 32 parameters can be shown in striplog at once. Previously it was 16. I have a requirement of displaying 40 parameters as of now. Is it possible that you roll out some update or patch to increase that amount? Or is there any script to run or anything that i can do on my side?

Interval data in 3D view
Good day. I want to ask you. How can I show interval data in the 3d view as tube ? And when I import data as shape file, my data show as small point, I can't change size. How can I change size of point ? Thank you in advance.

Create section from Line
Good day. I want to ask you, can I with target arcgis, to create section from selected line. And this line must be draw before It. For example it will be shape file or graphick line. IN the 3D Analyst for creating section, first draw lani in the dem or tin, and then we can see section getting from this line. Tnank you very…

Does the quiet mode in oasis montaj really makes the process faster for large files ?
Recently I came across a statement: When a script is executed, the oms program displays progress information on screen. If you want, you can suppress this feature, and improve the performance of your computer, reducing the time it takes to process large files. To enable quiet mode, type /Q after the project name in the…

no fill color
I want to color some grids but in some instances I want to put a color as invisible in order to highlight and show only the relevant colors I am interested in. Is there an option to put a color as invisible (i.e. no fill), for instance in the same way the the color options of excel or power point work for coloring cells…

VOXI, Why the "predicted data" not equal to "Gz_FWD" when i use a same model??
Hi I'm trying to extract the inverted model from VOXI and then input it for FW calculation in "starting model". The problem is that the predicted data from VOXI (the Fw calculation data) is unequal to the Gz_FWD (Fw calculation). These two gravity data (predicted data and Gz_FWD) also showed the difference value average of…

VOXI inversion of Density model of bouguer gravity seems not to be reality.
Hi I'm confusing about density Voxel model which inverted from VOXI Inversion. The inverted density voxel model of my bouguer gravity data (removed linear trend already) consisted of 2 layers (basin and basement) doesn't seem to be geological idea. This inverted density model show low density contrast at the deepest depth…
