The long field development period requires integrated approaches both to updating of geological information and implementation of production enhancement operations. The analysis of available literature about reservoirs with similar conditions in Russia and abroad made it possible to identify a pool of technologies related to improved oil production. An approach to comparative analysis of the effectiveness of applied technologies was offered. In the course of the look-back analysis of production enhancement operati...

Experience in the use of enhanced oil recovery methods shows that the main factor responsible for efficiency of the treatment is the correct choice of a particular technology for certain geological and physical reservoir conditions and the stage of development. Considering complex geological structure and low productivity of high-viscosity oil reservoirs in the Volga-Ural petroleum province, development of an integrated stimulation technology is a priority. The paper presents a promising concept of formation stimu...
