Designed For:
- Those who have a basic understanding of surface seismic acquisition and processing, but only limited knowledge of borehole seismic.
- Geophysicists needing higher resolution images than surface seismic can provide,
- Geophysicists who need to validate seismic processing parameters and imaging models using borehole seismic.
- Geophysicists wanting to learn how to use borehole seismic as a cost-effective reservoir monitoring tool.
Goal:
To enhance the participants’ knowledge, skills, and abilities necessary for understanding the applications of Borehole Seismic Data to Exploration, Reservoir Description, and Production, to be able to identify borehole seismic solutions to common seismic interpretation problems.
Objectives:
By the end of this course, participant will be able to familiar with the latest borehole seismic techniques in:
- High resolution imaging using 2D and 3D VSP surveys;
- Anisotropy determination and fracture analysis;
- Reservoir monitoring using time lapse VSP and crosswell seismic;
- Alternative acquisition schemes such as SWD and DAS.
- The design, planning and execution of advanced surveys and be comfortable with the interpretation of these surveys.
