What We Plan to do in 2009? Small Library of GPU modeling and migration codes. Full tests on range of topics for phase encoded modeling, migration, and imaging. migration, and imaging. Development of Hidden Markov Models.. Further improvements on matching filter Wyoming field test for getting signal from noise. Strong effort on waveform inversion (using Q adjustments) of land data. Perhaps elastic inversion tests. of land data. Perhaps elastic inversion tests. 3D preconditioned LSM applied to field data. Finish up LSD applied to VSP and SSP data.
