Geology & Reservoir

Geology & Reservoir

Reduce exploration risk and optimize field development with our comprehensive geoscience expertise, from sedimentology to seismic reservoir characterization, and from basin modeling to asset valuation. Our services span the natural resources life cycle and we have experts who understand the challenges faced at each step. For New Ventures and Exploration teams we provide support for proving new play concepts, ranking prospects and selecting drilling locations. We help asset teams build reservoir models, model economics, produce field development plans, and de-risk development drilling with on-site services. Our satellite mapping services provide remote exploration insight, and production surveillance, including pollution and ground motion monitoring.

CGG's Geology & Reservoir teams bring together the full scope of our geoscience knowledge and capability to provide solutions for your exploration, development and production challenges. We offer:

  • Comprehensive geoscience knowledge, tools and data
  • Valuable insight into all aspects of natural resource exploration and exploitation
  • Helping our clients to:
    • Gain a competitive advantage for frontier exploration
    • Reduce exploration risk
    • Optimize field development
    • Increase recovery and maximize return on investment
    • Improve cost and efficiency

We achieve this through the combined skills of some 500 experts located in some 24 regional centers who are aligned as single solution provider to best serve the needs of our clients.
