| Syllabus | Introduction to 2D seismic acquisition and geometry: types of sources and receivers, digital data, data sorting, reading and writing SEGY data, introduction to OSDU. CMP processing: normal moveout, velocity analysis and stacking. Static corrections: concept of datum and surface consistency, field, residual and refraction statics. Coherent noise suppression: multiple suppression by prediction error filtering, radon transforms, SRME; ground roll attenuation with source and receiver arrays, and FK filtering. Random noise attenuation with FX deconvolution. Post stack time and depth migration: exploding reflector model, migration by wavefield extrapolation, Kirchhoff migration, migration by diffraction summation, Fresnel zone and seismic resolution. Convolutional model and well to seismic tie. Computation and analysis of seismic attributes. Elastic wave equation, reflection and transmission coefficients, Zeoppritz equations and AVO. |
