Welcome and overview of aaspi accomplishments and software development

AASPI 2011 Software Development

  • 75% of the port to multiplatform performance (Linux and Windows 7)

    • aaspi_io – C++ code to read/write files and command lines

    • GUIs – C++ graphical user interfaces

    • all higher level aaspi algorithms

  • Developed and released the following new algorithms

    • som2d – clustering of waveforms/stacking patterns at each trace

    • som3d – clustering of attribute vectors at each voxel

    • nmo_mp – non-stretch normal moveout using matching pursuit

    • sof_prestack – prestack structure-oriented filtering

    • azim_offset_mig – simple prestack Kirchhoff time migration

    • aaspi_util_prestack – GUIs and scripts to handle migrated data

  • Prototyped the following new algorithms

    • Constrained 3D least-squares prestack time migration (working)

    • cwt, cwt_inverse, and bandwidth extension (needs aaspi_io)

    • Phase residue mapping of unconformities (needs aaspi_io)

    • High resolution (factor component) velocity analysis

  • Improved the following existing algorithms

    • sof3d – near total restructuring

    • dip3d – simplified and streamlined Kuwahara window options

    • spec_cmp, sof3d – significantly improved spectral balancing

AASPI 2011 Workflow Development

  • Calibration of curvature anomalies with outcrop analogues and image logs (Evan Staples – Hunton Lime; Trey White – Mississippi Lime; Nabanita Gupta – Woodford Shale)

  • Correlation of core linked to seismic attributes via depositional environment models (Nabanita Gupta)

  • Prediction of sand production from time-lapse AVO analysis (Sunday Amoyedo)

  • Prediction of geomechanical properties and well-bore stability through attribute-generated structure models, well logs, and prestack impedance inversion and time-lapse seismic (AliyaUrazimanova and Sunday Amoyedo)

  • Integration of outcrop flow directions, seismic stratigraphy, λρ-μρ inversion, and production data to identify sweet spots, Chicontepec Bain (Supratik Sarkar)

  • Developed and perfected constrained least-squares constraints and data prediction capabilities (Alejandro Cabrales-Vargas, Shiguang Guo)
