Introduction

• Bulletin Course Description

  • GEOP 510 Seismic Data Analysis (2-3-3)
    Amplitude variation with offset, anisotropy, dip moveout processing, seismic migration algorithms, time-lapse studies, multicomponent recording, converted modes, deterministic and statistical deconvolution, wavelet shaping, wavelet extraction, multiple suppression, and automated static correction. Processing packages such as Seismic Un*x, Hampson-Russell, Focus, and ProMax will be used during this course.
