Please refer to the documentation for functions from_array2D, from_array3D and from_array4D to see how the arrays are interpreted. The SEG-Y (sometimes SEG Y or SEGY) file format is one of several data standards developed by the Society of Exploration Geophysicists (SEG) for the exchange of geophysical data. Conversion is essential for users who need to analyze or visualize seismic data using different software tools. ABSTRACT R To support SEG-2 data import into MATLAB , I have modified a SEG-2 con-verter from the Colorado School of Mines Center for Wave Phenomena Seismic Unix package to convert SEG-2 files to corresponding MATLAB files. 2 (Icon7EFCFA81. mat). Description The seisio module provides methods to read and write seismic data in typical standard formats such as SEG-Y, SEG2 (read-only) or SU and can be easily extended.

SEG-Y files can be of different revisions or standards, including custom ones. Python Package Seismic processing and analysis are at the center of several activities ranging from exploration and production of reservoirs to hydraulic fracturing and underground gas storage. It improves on other implementations by having few non-standard library dependencies (only numpy) and being able to read file headers containing any field supported by the SEG2 standard. Added import of Geometrics . How can I do that? Subcommittee of the SEG Engineering and Groundwater Geophysics Committee, S.
