  5. Improving well productivity using: TECHNOLOGY OF THE COMPANY ESPROENKO EXPORT SL • Acid treatments • Water-isolating compositions • Heat treatments • Reagents for removing of hydrocarbons in PZP • Suppression and exploration of wells using special solutions • Protection of wells from corrosion and formation of hydrates • Ultrasonic treatment using installations of оwn production

  6. ESPROENKO EXPORT SL HIGHER PRODUCTIVITY WELLS INACTIVE DISPERSED SYSTEMS OF POWDERED REAGENTS The effectiveness of using the nitricacid and substances on its basis enables: - effective reaction with the layer; - products of reaction with the layer reduce the viscosity of oils with a large content of asphalt and tar components; - produce the de-emulsifying effect on the watered layer oil.

  7. To prevent the corrosive effects of acids in the borehole equipment it is transferred to an inactive form.-nitric acid with urea-urea nitrate salt forms a (NC) for response:HNO3 + CO(NH2)2 [CO(NH2)2HNO3]. ESPROENKO EXPORT SL Urea nitrate – a white crystalline substance with density of 1746 kg/cu.m. Corrosion activity of the powder:wet (dry)-3989 g/m 2-hour at 0.37% water content-0.06 g/m 2-hour. content of nitric acid in dry product- 48% Fig. 2. Dependence of urea nitrate corrosion changes on temperature

  8. Nitrate urea (urea complex nitric acid) is resistant to its physical and chemical composition of up to 110° c. ESPROENKO EXPORT SL • During the dilution with water there is a gradual breaking down of urea into nitrate source with formation of products-nitric acid and urea. This makes it possible to increase the depth of the layer when exposed to complex, compared with pure acids. Fig. 1. The dependence of solubility of urea nitrate changes in water on temperature

  9. Since the destruction of the complex by diluting it with water, declining concentrations of nitric acid in solution, then choosing one or another degree of dilution is adjustable and depth of productive layer acid exposure. When you make a reagent in excess, you can maintain the concentration of nitric acid in solution-4.8% -26.5. The dependence of concentration of nitric acid on the temperature of the fluid is described by the following formula: Cнк = 0,000074T3 - 0,012T2 + 0,885T - 8,6 where T is the temperature of the solution, С. Urea has the ability to improve the wettability of the rock, increasing the effectiveness of acid exposure during removal of reaction products of bottom hole formation zone pore space. ESPROENKO EXPORT SL

  10. Urea nitrate for delivery to the bottom hole of the well and the impact on the bottom area of productive layer, use organic liquid: anhydrous oil, heavy oil, light oil, condensate. Solvent power of urea nitrate relative to urea quartz and clay minerals (fig. 4): in 9 times lower than HCl; the 4.5/ -5.5 times lower than HNO3 ESPROENKO EXPORT SL

  11. ESPROENKO EXPORT SL Urea nitrate and compositions on its basis can be used to increase the productivity of sand collectors and injectivity of injection wells because urea is pretty well dissolved silicate making up species (table 1). Limitations depending on lithological compound rocks, as in the case of using hydrofluoric acid, are missing.

  22. Effectiveness of GTS in production wells depends upon the possibility of withholding agents in aquifer of insulating the manifold. Therefore, typing in an insulating liquid substances and was giving it a magnetic operated liquid property, you can deduct magnetic active insulating solution of magnetic field in the aquifer of the collector-in hole, permanent magnet ESPROENKO EXPORT SL

  23. ESPROENKO EXPORT SL The well device is connected by a parallel set of permanent magnets 1 (fig. 2) included in the magnetic circuit using two magnetic circuits 2. Permanent magnets are shifted relative to 1 magnetic circuits 2 and non-working face that increases the resistance to flow out of the butt end of a magnetic tape system and leads to a redistribution of the magnetic the flow towards the working face. Elementary magnet systems are placed around the circumference of a cylindrical magnetic enclosure 3 and pointing at each other to strengthen the magnetic field on the surface of the device by "pushing out" the last out. To prevent bypass surgery within the magnetic system of permanent magnets filled cavity sealing nonmagnetic material, elementary magnet systems are placed around the circumference of a cylindrical magnetic enclosure 3 and pointing at each other to strengthen the magnetic field on the surface of the device by "pushing out" the last out. To prevent bypass surgery within the magnetic system of permanent magnets filled cavity sealing nonmagnetic material.

  24. Schematically the process isolation in water production wells is implemented as follows. Secrete oil-and water-saturated reservoir intervals. Prepare an aqueous solution of polyacrylamide with addition of substances, magnetic-active alkali metal carbonate and surfactant, aqueous solution polyvalent metal. Flushed down the saturated magnetic field generator shooting interval (SGMP). Tie the wellhead with special equipment and pump into a well insulating solution. Then stir up the solution of water-soluble salt two-or trivalent metal. This is a solid structure that prevents entry of isolating water in the well. The waterproofing barrier of magnetic active particles of matter under the influence of a constant magnetic field effectively isolates the water-bearing stratum of. ESPROENKO EXPORT SL

  25. The formation of a solid structure is contributed by: -presence of magnetic active substance in a polymer solution; -formation of cross-linking in the polymer; -deposition of insoluble precipitate by reacting alkali metal carbonate and soluble salts of polyvalent metal which provides reinforcement and bolsters a structure of oil well screen 3Na2CO3 + Al2(SO4)3 + 3H2O  3Na2SO4 + 2Al(OH)3 + 3CO2; -formation during the reaction sintering carbon dioxide surfactant. Based on these studies in fishing practices it is possible to implement the following process flow diagrams-insulation of cracks formation and isolation of a watered formation interval.
