I want to know if it is possible to construct a 3D structural model for a certain area using "Midland Valley Move software" by utilizing boreholes only.
You can construct a 3D structural model using boreholes in Move software. Indeed, you can construct it in other free or cheaper-licenced programs. However, the most important thing to bear in mind or what you should ask yourself is: what is the purpose of this "3D structural model" and what really means for you a "3D structural model".
One thing is to construct a fence diagram (which usually is in 3D or quasi-3D) using formation tops or stratigraphic information (e.g., lithology, thickness, etc) from the boreholes, a fence diagram like that one suggested by Bayan Hussien, which is very useful to correlate stratigraphically. However, from a fence diagram, you will hardly construct a reliable structural model even a 2D structural model!. So, a reliable structural model must be at least balanced or geometrically consistent, in this way, you should have more structural data and a seismic line will be very useful to interpret structures.
Another important thing is the space between boreholes, you must consider that the greater spacing the greater unknown information in between (uncertainty increase dramatically).
Please consider the above examples (image) constructed from borehole data. In case #1, from the stratigraphic correlation in the fence diagram, you can infer a simple structural model with horst and graben structures related to planar normal faults. However, in case #2, from the same data/information you could interpret another structural model related to listric faults. So, the important point is, what is the detail or purpose of your work, depending on the latter, you can assess if move software is what really do you need or the advantages/disadvantages of constructing a (likely complex) "3D structural model" using only a limited borehole data.
Move software is very useful when you have a seismic line or very dense structural information.
Anyway, I hope I have understood your question correctly and be able to help a little.
@Huber A. Rivera Rosado. Thanks for your insight. Could you kindly share some free packages for creating fence diagrams? I am very much interested in trying my hands on them. Thank you.
I think it is available to construct a structure model depending on well logs only, but without seismic data, the accuracy of this model will be very low.
