RGM: Random Geological Model Generation package
We develop a Fortran package for generating realistic random geological models, including seismic images, faults, relative geological time (seismic horizons), and salt bodies, via a multi-randomization method. The generated models can be used to train machine learning models, e.g., MTI-MTR.
The work was supported by Los Alamos National Laboratory (LANL) Laboratory Directory Research and Development (LDRD) project 20240322ER. LANL is operated by Triad National Security, LLC, for the National Nuclear Security Administration (NNSA) of the U.S. Department of Energy (DOE) under Contract No. 89233218CNA000001. The research used high-performance computing resources provided by LANL's Institutional Computing program.
The work is under LANL open source approval reference O4778.
A manuscript associated with the code is under preparation and will be released pending separate approval.
RGM depends on FLIT.
The code is written in Fortran. To install RGM,
cd src
make
The compiled library file (with a name librgm.a) and module files will be at the directory lib.
We include several simple examples to use RGM in example. To try these examples,
cd example
make
The compiled executables will be at example/bin. Running these executables will generate images/faults/salt bodies in the directory. All the generated files will be in little-endian single-precision raw binary format, with dimensions specificed in the respective codes.
The Makefile in the example directory can serve as an example on how to use RGM in your code, including path inclusion and link of the compiled library/modules.
