Analysis of Hydrodynamic Methods for Enhancing Oil Recovery

In the modern world, the hydrocarbons represent a raw material for various industries, therefore, the fight against the problem of extracting residual oil is relevant and important at this stage of human development. In connection with the high demand for hydrocarbons and the rise in world oil prices, research is being actively carried out on methods for enhancing oil recovery. Hydrodynamic methods of enhanced oil recovery represent one of the most effective and relevant methods by which the residual oil can be extracted. According to this, the current article pays special attention to several types of hydrodynamic methods forenhancing oil recovery. In this work it has been focused on three main types of hydrodynamic enhanced oil recovery methods; unsteady (cyclic) waterflooding, changing the directions of flows and forced fluid Extraction.
