Description
Pre-requisites:
Recommended to take ‘Rock physics, Well logs and Well tie for Seismic Exploration and Production’ course first
This course covers time-lapse (4-D) seismic and multi-component (MC) seismic theory and applications. The ability to monitor reservoirs and take appropriate development decisions with 4-D seismic data is key. This requires understanding of complex seismic acquisition, processing, and analysis methods. Further, node technology and elastic FWI imaging is advancing the advantages of multi-component seismic data in the industry. This course shows how to optimally use 4D and MC data (from theory to practical applications) to improve successful asset management and reduce risk. It also allows geoscientist to better communicate with engineers and the engineers to understand usage and pitfalls of 4-D and MC seismic methods. The instructor is one of the most experienced people in the industry in this area with substantial field project execution experience.
