going• Brad Wallet – (Ph.D. – Geophysics) – to Schlumberger

• 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 Software 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 (Aliya Urazimanova 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)
