2. The traditional approach to solving the problems of PRM
Today PRM paradigm is based on the use of two methods (in order of
priority):
1. 4D seismic on reflected waves (subtraction 3D cube reflectors)
2. Passive surface microseismic monitoring (plan to do)
Our new approach: CSP-PRM within the concept of CSP-
Approach
The proposed new paradigm CSP-PRM is based on the use of two
methods (in order of priority):
1. Surface microseismic monitoring, based on the method
MicroseismicCSP
2. 4D seismic on scattered waves using the method FtactureCSP
(subtraction CSP-diffractor cubes)
CSP- Permanent Reservoir Monitoring (CSP-PRM)
