Physical methods of enhanced oil recovery (review)
The paper provides an overview of physical methods of enhanced oil recovery: hydro gas-dynamic fracturing, horizontal wells, wave and combined methods. The above overview of the physical EOR shows that each method has its own application scope, advantages and disadvantages, and it is confirmed by the results of pilot tests conducted at different fields of the Russian Federation. Analysis of the literature suggests that physical methods of enhanced oil recovery are promising in terms of efficiency, energy and resources saving, but the choice of the method for the successful treatment of wells bottom area requires evidence-based approach.
