Prof. of Geophysics!) out going

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 2 D color bar) • Prototyped the following new algorithms • Constrained 3 D 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) 4

AASPI 2012 Geologic Focus • Barnett Shale • Woodford Shale • Mississippi Lime • Red Fork Channels • Fractured Basement • Conglomerate “Wash” (Mexico) 5

Most applications have a flow chart 8

Many applications now have gray “Theory” boxes 9

Followed by instructions defining parameters and how to complete the GUI 10

These are followed by references and examples 11
