Methods and Software for Interpolating/Modelling of Stratigraphic Well Data in 2D/3D?

Question

I have some geologic well data. The lithologies have been interpreted, and stratigraphic columns have been drawn. The columns have been adjusted for elevation, and correlation has been done between seemingly continuous layers.Is there a more sophisticated 2D/3D program, preferably open source or free trial (I'm a student), that could be used to map the area better with an interpolated or block diagram result?

Answer 1

Yes! There are several methods and software options for interpolating and modeling stratigraphic well data in 2D and 3D. Below are some recommendations based on your needs:

1. Open-Source and Free Software

a) QGIS + Plugins

1. QGIS (Quantum GIS) is an excellent open-source GIS platform that supports geological interpolation.
2. Plugins like QGIS 3D or SGeMS (Stanford Geostatistical Modeling Software) allow for geological modeling.

b) GemPy (Python)

1. An open-source 3D geological modeling package that uses implicit modeling techniques.
2. Works well for stratigraphic correlation and interpolation between wells.
3. Requires Python but offers great flexibility.

c) Leapfrog Viewer

1. While Leapfrog Geo is proprietary, Leapfrog Viewer allows you to visualize models shared with you.
2. If your institution has a license, you may be able to access Leapfrog Geo for implicit stratigraphic modeling.

d) GeoModeller (Free Trial)

1. A 2D/3D geologic modeling software designed for stratigraphic and structural geology.
2. Provides implicit modeling tools for interpolating stratigraphic layers.

e) Visible Geology

1. A web-based simplified stratigraphic modeling tool.
2. Good for quick block diagrams and cross-sections.

2. Proprietary Software with Student Licenses/Free Trials

a) Petrel (Schlumberger)

1. Industry-standard software for stratigraphic and reservoir modeling.
2. Offers powerful interpolation methods (Kriging, IDW, etc.).
3. Student licenses may be available through university partnerships.

b) Move (Midland Valley)

1. Excellent for structural and stratigraphic modeling.
2. Free trial and student licenses available.

c) Surfer (Golden Software)

1. Useful for 2D stratigraphic interpolation.
2. Generates contour maps, cross-sections, and block diagrams.

d) RockWorks

1. Great for subsurface geologic modeling and lithologic interpolation.
2. Offers free trials and student discounts.
