This course will provide knowledge and understanding of how to use the Omega software processing package to process a land 2D seismic dataset through a classic time processing sequence. It will include the parameter review of production flows. The use of the Interactive Velocity Analysis application (InVA) will be covered to pick a stacking velocity field.
Alongside this the participant will learn the appropriate QC for each step of the processing sequence and how to sort data to different domains. At the end of this class participants will be have the skills needed to be a contributing member of a production processing team.333
Introduction, Project Set-up, Reformat and Merge Geometry
At the end of the session the student will be able to reformat an example SEG-Y dataset and be able to explain the key parameters. They will create a geometry database and merge it with the seismic data. They will be able to sort from shot domain to CMP domain and generate an initial velocity field.Day 2
Noise Attenuation, Surface Consistent Deconvolution and Amplitude Analysis
At the end of day two the student will be able to choose parameters for and test random and coherent noise attenuation and surface consistent techniques. They will be able to QC the results and discuss and the effects before and after stack.Day 3
Velocity Picking, Residual Statics
At the end of this session the student will be able to prepare the data are for velocity analysis and pick and analyze velocities using InVA. They will be able to generate residual statics, apply them to the data and QC the result.Day 4
Migration Preparation, Migration and Post Stack Processing
At the end of this session the student will be able to create and QC migration velocities, prepare the data for time migration and choose appropriate post-stack processing parameters.
This course is intended for geophysicists with a basic understanding of Omega who wish to learn how to use the software to process a 2D land time dataset.
An understanding of the concepts underlying seismic data processing and common data processing challenges. Participants without any prior knowledge of Omega must have taken the Fundamentals of Omega class before enrolling for this class.
