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.

Storengy combines all the expertise necessary for the qualification, development and commercialisation and operation of storage sites. The company designs builds and operates all types of underground gas storage (UGS) facilities, and offers its customers top-quality services based on its extensive know-how. Storengy is one of the few operators in the world to combine skills as varied as market analysis, subsurface sciences, drilling and completion techniques, underground reservoir engineering, operation of surface industrial facilities and industrial safety. Relying on this expertise, Storengy has become one of the world leaders in underground natural gas storage. We provide our customers with innovative products through its experience in offering Sales & Marketing services on various markets and their relevant regulatory environment. Storengy develops and operates underground natural gas storage sites in France, Germany and United Kingdom. 

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 is 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
  • Sratigraphy
  • Hydrogeology
  • Reservoir engineering (simulation of multi-phase fluid reservoirs)

Internationally renowned for its salt caverns expertise:

  • Site identification
  • Cavern leaching 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 modelling
  • 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 behaviour
  • Pipeline integrity (corrosion and metallurgy)
  • Detection and gas quality measurement
  • Health, safety and environment (impact of products used and hazardous phenomena modelling)

Wells
