Seismic Emerging of Subsurface Geology Course
Introduction:
The goal of this course is to help those who work with reflection seismic data comprehend and value the fundamental ideas and procedures that produce final images and their corresponding characteristics. In order to establish the goal, guiding principles, parameterization, and constraints of the many processing steps leading to the final seismic images produced by the most recent state-of-the-art imaging techniques, basic seismic imaging principles and techniques are introduced at the beginning of the class. 3D seismic data is the course's main focus. By the end of the course, the participant will be able to identify potential issues introduced or not mitigated by the processing flow, as well as comprehend and value the several phases leading to final interpretable images. Additionally, the participant will comprehend how seismic amplitudes are affected by data processing and acquisition procedures.
Course Objectives:
How To:
- Assess and determine data processing flows for a variety of acquisition and reservoir scenarios
- Determine the most cost-effective imaging or migration technique given acquisition and structural scenarios
- Recognize various noises and how best to mitigate them
- Assess and appreciate the sensitivity of data processing parameters on final images
- Estimate the vertical and lateral resolution of the processing and attribute products
- Understand and examine data acquisition and processing quality control displays
- Ask appropriate questions during data processing steps
- Communicate effectively with specialists in seismic data acquisition, processing, and interpretation
- Appreciate and evaluate the trade-offs between costs, turn-around time, and sophistication of processing and imaging steps
