Description

Active monitoring: This course aims at presenting through lectures the theory and the principles of active monitoring seismic methods. At the end of this lecture, the students would be able to define a feasibility study and a 4D seismic workflow, identify the seismic parameters sensitive to a change in fluid in a reservoir coupled to the effects of production on these parameters. Some order of magnitude of 4D effect on seismic data would also be given during this course.
 

Compétences visées

At the end of this unit, the student will be able to:

• Identify the parameters of a reservoir that are likely to change with a fluid substitution
• Carry out a feasibility study on the expected seismic response in a reservoir in the event of a change of fluids in place
• Define the best network strategy in order to record and analyze micro-seismic event
• Apply modern technique for seismic event detection and location
• Process seismic event records in order to retrieve information about the stress state
• Use the seismic signal to monitor variation of the seismic velocity and interpret them in terms of reservoir mechanics
