“…An example is the innovative technology of plasma-pulse treatment (PPT), which has been tested in oil and gas production, and creates secondary permeability in the reservoir and connects the system of natural fractures (cleavage), thereby increasing the permeability of the reservoir over a large area. The PPT technology itself as well as the references to case studies providing enhancing of oil production with application of PPT are provided in [9,10]. The experience of applying the plasma-pulse technology at oil producing and injection wells has shown a multiple increase in the production/injectivity of treated wells.…”

The contribution of renewable energy sources to the total electricity production in the world is steadily increasing. At the same time, the share of geothermal energy in the overall balance remains unjustifiably insufficient. The prospects for obtaining heat from the earth are limited by a number of technical and technological difficulties, which especially applies to that part of geothermal energy, which is called petrothermal. The article proposes an approach to improve the efficiency of a petrothermal power plant while maintaining the general concept of environmental friendliness.

“…Also, this work examines the basic problems of recovery of residual crude oil from the well. The use of pulsed plasma systems has been proposed as a useful solution [3][4][5]. An experimental study on the intensity of PPS was done by Ageev et al In this work, and pulsed plasma systems are considered a good alternative for hydraulic fractures in low-permeability reservoirs, increasing reservoir rocks' inherent permeability with dynamic shocks.…”

Simulation and experimental studies have been used in this paper regarding the importance of the plasma pulse system (PPS) to create a uniform discharge plasma channel and a strong shock wave. First, the effect of wire geometry on uniform plasma production is simulated. The simulation results show that a wire with a diameter of 0.4 mm and a length of 50 mm is an ideal geometry for the plasma pulse system because it produces a more uniform plasma. Second, the shock wave generation mechanism was investigated experimentally in the explosion process of two wires with thicknesses of 0.2 and 0.4. As the diameter of the wire increases and its resistance decreases, the discharge current peak increases, and the tendency to establish periodic currents increases, so the 0.4 wire gives better experimental results in terms of shock wave power than the simulation results that confirms the smaller the diameter of the wire, the current generated in a pulsed manner in a short period, and sufficient energy is not stored to change the state of the wire and, as a result, to create a strong shock wave in the wire. Finally, it simulated underwater using COMSOL Multiphysics. It shows that the pressure drops immediately after the explosion point. Based on this, a pressure of 20 MPa has been obtained at a distance of 10 cm from the explosion point, and this reduction rate continues exponentially.

Advanced technology of increased hydrocarbons recovery – Plasma Pulse Treatment (PPT) is presented. The explanation of physical impact on the reservoir is given. Examples of laboratory studies and field-testing observed. The physical bases of the PPT are periodic pulses of equal strength, spaced with equal time intervals by discharge current passing through a metal conductor. Shock wave, formed by the explosion of conductor, is propagating radially with supersonic speed, gets out through the perforation holes and provides an elastic compressive and tensile impact on the media. Low frequency waves, propagating deep into reservoir, contribute to the development and formation of new cracks, as well as the transformation of sub-capillary pores into capillary, causing the liquid moves from stagnant zones and channels to the zone of active drainage. The paper presents the description of the physics of a process as well as some calculations and estimates of observed technical parameters. Some estimates and calculations, given in the paper, are based on the principles of nonlinear physics and fluid dynamics. Laboratory studies confirmed substantial changes after PPT application both in oil samples (resulting in viscosity reduction) and core samples (increase of permeability). Microseismic studies, carried out on the field, registered the propagation of waves, created by PPT, on a distance of over 1.3 kilometers away from a treated well. Number of well studies both production and injection ones is presented, showing the long lasting effect of treatment. The overall analysis of over 300 treated wells is given, proving the high efficiency of Plasma pulse technology. Technology, presented and described in the paper, allows increasing the productivity of hydrocarbons wells and involving the reserves of residual and unrecoverable oil into production.
