Single-Course English 5 ECTS

Enhanced oil recovery and carbon dioxide storage

Overall Course Objectives

To provide knowledge of the modern methods of enhanced oil recovery (EOR). The course describes: 1) PHYSICAL PHENOMENA occurring under two-phase flows in porous media; 2) Engineering ideas behind the EOR, and 3) MATHEMATICAL MODELS of the EOR and carbon storage processes.

Learning Objectives

  • Describe classification of the methods of EOR, and necessity for their application
  • Describe the underlying physical concepts and the derivation of the basic transport equations for multiphase flows in porous media, and in particular, the classical Buckley-Leverett (BL) theory of waterflooding
  • Describe the methods of reservoir simulation
  • Solve graphically the BL equation in one dimension and calculate basic parameters of waterflooding, like time of the water breakthrough, saturation at the breakthrough front etc.
  • Evaluate criteria for physically reasonable laboratory studies of the waterflooding. Describe practical problems and new phenomena occurring under the visualization experiments with application of the X-ray computer tomography scanner
  • Evaluate the effect of gravity on waterflooding and other methods of the EOR, in particular, on the stability of displacement
  • Evaluate the effect of heterogeneity; classify the reservoirs according to the flow regimes (viscous-dominant, capillary-dominant etc.); apply analytical methods of upscaling
  • Describe the principles of application of miscible and immiscible gas injection, their advantages and shortcomings; Predict the main parameter of the gas injection, the minimum miscibility pressure, with the help of a software
  • Describe the principles of engineering application and underlying physical mechanisms of carbon dioxide injection and water-alternate-gas (WAG) injection
  • Select a chemical (surfactant, polymer/micellar) etc. for chemical flooding, on the basis of their known properties
  • Describe and evaluate the processes occurring under carbon dioxide injection in the aquifer or in a depleted oil reservoir.
