The article shows that modelling and design definition of the impact requires the differentiation for a specific well-formation system. The authors found that the effective use of acid-clay exposure in terrigenous strata is possible in various geological and technological conditions considering the criteria for the impact applicability and the implementation of a specific impact design. They proposed to use selective acidic solutions of selective action to increase the efficiency of secondary acid treatments.

The paper studies the dynamics of fracture reservoir management during the solution of the problems of the increase in the efficiency of development of oil deposits with hard-to-recover reserves. The directions of the creation of models of multichannel telemetry systems are studied from the point of view of the proposed concepts, as well as the conditions under which the study of well conditions is carried out. The results show that these telemetry systems can function in a well when the sensor elements are integrated, which are based on a single-core armored cable.

The researchers have developed simplified models of the studied formations in the Langepasneftegaz TPP to forecast the effectiveness of using non-stationary waterflooding with flow control and flow diverting technologies. To increase oil recovery and intensify the influx of oil from the reservoirs, they recommended the integration of technologies. The article shows that complex technologies for impacting oil and gas deposits using non-stationary waterflooding aimed at increasing the oil recovery coefficient and limiting the movement of water in the reservoir while stimulating the bottom-hole zones of the reservoir will significantly increase the efficiency of field development.

A new methodological approach is presented in determining design of current clay acid treatments of wells. The proposed scientific and methodological approach allows differentiating for different groups of objects in the Langepass region to determine certain technological parameters of impact on the bottom hole zone of formations, taking into account the features of geological and physical properties of formations and fluids saturating them. In special cases, it is suggested to use acid retarders for reaction with rock. The authors proposed algorithm for determining wells where the maximum effect can be obtained at a specific time.
