CSP Permanent Reservoir Monitoring

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)

Main proposal for CSP-PRM microseismic (Seafloor&Land)

The layout of surface registrars:

• Inline: 50 m

• Crossline: 100-150 m

Crossline: 300 m Density of sensors: 77 sen./sq. km (39 per cycle)

Crossline: 150 m Density of sensors: 137 sen./sq. km (69 per cycle)

Crossline: 100 m Density of sensors: 193 sen./sq. km (97 per cycle)

Traditional scheme for 4D New scheme for 4D, 150m New scheme for 4D, 100m
