Course Content

  • NATURAL GAS: AS A STORABLE ENERGY

      • Why store natural gas? Needs expressed by suppliers, administration and network operators.
      • How? Summary presentation of the different storage systems: depleted reservoirs, aquifers, salt domes.
      • LNG storage tanks, etc.
      • Where? History of underground gas storage, storage sites in Europe and worldwide. Maps and tables by types of storage, per country and stored volumes.
      • Gas storage and its environment: noise, exhaust, surface footprints, landscape integration, local taxes, workforce.
  • STORAGE TYPES

      • Fluid flow in porous media. Reservoir modeling.
      • Depleted reservoirs, aquifers, salt domes, LNG storage tanks.
      • For each type of storage, presentation of development conditions, geological and structural characteristics, their specificities, the inherent hazards, the operational constraints, the repartition of sites throughout the world, etc.
  • STORAGE EQUIPMENT

      • Wells: drilling specificities, downhole and surface equipment.
      • Gathering network.
      • Gas compression: why, when and how?
      • Extracted gas treatment: dehydration, sweetening, odorization.
      • Auxiliary equipment: manifolds, instrumentation and control system, safety, treatment of effluents.
      • Metering: primary meter, correctors, data processing.
  • COMPRESSION

      • Characteristics of compressors specific to natural gas storage sites: compression ratio, runtime frequency, environment related issues (exhaust gases, noise, etc.), power types.
      • Types of compressor units: driver type (engine, electrical motor, gas turbine, etc.), reciprocating or centrifugal compressor, etc.
      • Comparison between gas turbine and motor drivers, fuel gas and electricity power.
  • GAS TREATMENT

      • At the wellhead: hydrate prevention by heating or methanol injection.
      • In the station: dehydration, sweetening, odorization.
      • For each treatment, presentation of the treatment target, risks, regulation aspects, treatment techniques, common processes used for gas treatment and product regeneration, effluent treatment.
  • ECONOMICAL ASPECT OF GAS STORAGE

      • Life cycle of a gas storage site.
      • Estimated values for CAPEX and OPEX for each storage type.
      • Pricing of access of third parties to storage facilities in France: analysis of the price breakdown, taking into account constraints and specificities of the storage.
      • Simulation of cost price per kWh, stored or delivered, for common site configurations.
