Directional drilling 3D visualization modeling

[xiaohua00921]

What is your question?
Hello, in your example, the unknown model is imported into the drilling data visualization 3D modeling, your data are all vertical drilling data, I wonder if you could provide some data like directional drilling and be able to visualize an example of modeling? Because as you know directional drilling data is oriented by inclination and azimuth.

A little help would be greatly appreciated.

Hi @xiaohua00921,

if you look through all the examples at the gempy page and on the way input data is loaded (e.g from csv files), you will see that data for surface points is added using xyz coordinates. This does mean that you cann add surface boundary information any way you like, there is no restriction to follow a vertical drillhole.

Let me know if this answers your question.

Cheers,
Jan

Hello, javoha.
This modeling based on the drill data xyz is helpful for me, but I still want to ask one thing, the columns in the online data don't seem to correspond very well, including the column with the name of 789, I would like to ask you to help me to answer what these columns represent and how they are used in the modeling process, I always feel that some of the data is not used, this question may cost you a lot of time. I would like to thank you very much for your generous help.

Also, I would like to ask you, when you say that the vertical drill holes are unrestricted, do you mean that based on these corresponding drill hole data, according to your gempy algorithm, it is possible to successfully connect them into such a directional trajectory (a line with direction)? My research direction is 3D modeling of coal mining, mainly based on the existing borehole data, interpolating each layer of lithology according to your corresponding method (if the data volume is large enough), and then updating this model according to my subsequent data afterwards, I wonder if gempy can be used in my direction, do you think it can be?

Addendum To the first reply, I'll show you the borehole data in your example, it's in this graph, can you please elaborate on the meaning of this,altitude,base,formation,top,_top_abs,md, for example his altitude, is this altitude the z-value of the borehole, and base is based on who? base is an altitude based on who? The meaning of these data and so on. Thanks again if you can answer my questions.
