Welcome and overview of aaspi accomplishments and software development

AASPI 2012 Software Development

  • 85% of the port to multiplatform performance (Linux and Windows 7)

    • GUI connection to application programs via parameter files

    • Device independent graphics

    • C library utilities to simplify GUI maintenance and port

    • implemented “intelligent” GUI defaults and expanded GUI provided documentation

    • two python scripts to replace shell scripts (only 30 to go!)

    • all but one SEP module (Math) gone!

  • Developed and released (some in December 2012) the following new algorithms

    • gtm – clustering using generative topographic maps

    • cwt – Marcilio’s version of spectral decomposition with bandwidth extension

    • Phase residue mapping of unconformities

    • High resolution (factor component) velocity analysis

    • complex_stratal_slice (stratal slices of complex spectral components)

    • complex_pca_spectra (PC-filtering of complex stratal slices)

    • crossplot (plots two attributes and displays against a 2D color bar)

  • Prototyped the following new algorithms

    • Constrained 3D least-squares prestack time migration (input for diffraction imaging)

  • Developed multiple utilities

    • aaspi_mpi_kill (kills MPI jobs)

    • aaspi_cleanup (cleans up the large number of intermediate files)

    • aaspi_set_default parameters (sets installation or personal defaults)

    • aaspi_geometric_workflow (defines a common multiattribute workflow)


Welcome and overview of aaspi accomplishments and software development

AASPI 2012 Geologic Focus

  • Barnett Shale

  • Woodford Shale

  • Mississippi Lime

  • Red Fork Channels

  • Fractured Basement

  • Conglomerate “Wash” (Mexico)
