SeisMovie is CGGVeritas’ solution to high-resolution onshore reservoir monitoring.

Using buried sources and buried receiver arrays, data are acquired continuously and autonomously to provide a seamless, high-resolution movie of your reservoir.

The system offers unparallelled sensitivity and can capture subtle and rapid reservoir variations which conventional 4D techniques fail to resolve. SeisMovie is both versatile and environmentally friendly, with a wide range of applications.

The autonomous system works 24 hours a day, recording and pre-processing data on site before transmitting it back to the office for analysis.

FEATURES

• Continuous automated seismic data acquisition
• Remote operation and data recovery
• Buried source and receiver installations for high sensitivity and optimum 4D repeatability
• Versatile and flexible design can target vertical and/or spatial reservoir variations
• Applications for monitoring:
  - Subsurface gas storage
  - Steam and water injection enhanced production
  - Reservoirs with small 4D signatures

BENEFITS

• Captures subtle reservoir variations
• Enables monitoring of previously unsuitable reservoirs
• Provides continuous monitoring for real-time production decisions
• Highly reliable remote autonomous operation
• Minimal environmental impact
• Minimal surface interference at busy production sites

A shot gather summation for 24 hrs of recorded data after basic pre-processing and NMO correction. The frequency content at the base of the reservoir is up to 240Hz. This data is acquired and pre-processed autonomously before being transmitted from the remote site to the office. A noise cone centred on the source location is visible at this preliminary stage.
