A renowned expertise

 

Storengy is one of those rare companies that combines all the expertise necessary for the qualification, development and commercialisation and operation of storage sites for all four technologies available.

 

 

Design and development


• Storengy is involved from the very beginning of a storage project, during the site's evaluation phase, both for underground storage and surface facilities.
• Qualifying potential sites:

  • analysis of petrophysical and geological data from logs
  • core testing
  • interpretation of 2D and 3D seismic studies
  • geological and hydrogeological structure studies
  • reservoir engineering

• Development of new structures, for all types of storage.
• Drilling of exploration, operation and control wells. Performing tests on wells.


Reservoir modelling at the heart of Storengy's activities


• Geoscience expertise:

  • exploring potential sites and operating site reservoirs in the production phase
  • geophysics (2D, 3D and 4D seismic data acquisition and interpretation, structural interpretation and reservoir characterisation)
  • petrophysics (log and core analysis)
  • sedimentology
  • stratigraphy
  • hydrogeology
  • reservoir engineering (simulation of multi-phase fluid reservoirs)

 

Internationally renowned for its salt caverns expertise


• Site identification
• Cavern leaching (watch the film here) and technical and contractual brine management
• Geomechanics (cavern stability and surface subsidence)
• Thermodynamic behaviour
• Salt chemistry
• Exploration assignments and on-site missions in the operational phase

 

Well assignments

• Work preparation and well architecture design
• Steering heavy operations (drilling, work-over and snubbing)
• Maintenance operations, wireline and log analysis
• Drilling (watch the film here), cementing, design and equipment assessment
• Long-term operational supervision of wells:

    • heavy maintenance operations (work-over and snubbing)
    • wireline, log analysis, and well integrity management

 

Surface facility, design operation and maintenance

Operation and maintenance


• All operation tasks:

  • remote continuous management of surface facilities
  • site manoeuvres, reception, outside operator monitoring and management
  • industrial safety management

• Computer-aided maintenance management

  • management of sub-contracted maintenance services

 

New facility design and surface facility operation expertise


All industrial areas are covered. Expertise is applied to project and operational teams to maximise facility operation (treatment process engineering, compression expertise, automation and instrumentation, IT, electricity, piping, civil engineering, etc.).


Project management: prime contractor and project owner assistance, site works coordination, and outsourced engineering contracting (EPCC and EPCM).

 

R&D and new storage technology

Research & Development

• Multi-disciplinary research programme leveraging on both internal expertise and that of GDF SUEZ
• Numerous partnerships with other entities (IFP Energies Nouvelles, Ecole des Mines de Paris, Ecole Polytechnique, SMRI, etc).

The areas of research cover, for example:


• Geosciences

  • development of 1D and 3D (multi-fluid) proprietary tools for reservoir modeling
  • production well supervision
  • salt cavern creation and monitoring software
  • creation of pilot lined rock caverns
  • long-term behaviour of aquifers

• Surface facilities

  • process modelling (two-phase flow in pipelines and treatment quality)
  • compressor unit behavior
  • pipeline integrity (corrosion and metallurgy)
  • detection and gas quality measurement
  • health, safety and environment (impact of products used and hazardous phenomena modelling)

• Wells

  • research and development
  • new technologies and intervention protocol testing

 

New storage technologies


• Biomethane
• Compressed air storage
• CO2 storage

 

Sales & Marketing and asset performance management


Sales & Marketing


• Sales of storage capacity operated
• Regulation & energy market analysis expertise
• Innovative products & services to meet market expectation
• Market analysis:

  • assessment of energy and gas requirements
  • identification of needs in terms of modulation and flexibility
  • identification of potential suppliers of flexibility

 

Asset performance management


• Monitoring storage performance:

  • checking reservoir and well productivity
  • monitoring water and sand production levels
  • checking surface facility performance
  • managing reservoir production by arbitrating the use of wells
