  1. Complex approach to increasing the productivity of wells

  2. During more tan 20 years of hard work in several countries, our company has developed our own technologies and our own chemicals por increasing the productivity of oil and gas Wells. We own more than 300 patents for different technologies and chemicals, and run our own chemicals manufacturing facilities.

  3. Our technologies and chemicals allow us to solve a wide range of problems in oil and gas wells, increasing significantly their productivity. Improving Wells productivity using: -Acid Treatments. -Water-isolated compositions. -Heat treatments. -Reagents for removing of hydro-carbons in the bottom-hole formation zone. Supression and exploration of Wells, using special chemicals. Protection of Wells from corrosión and formation of hidrates.

  4. Some of our technologies

  5. INCREASING OF WELLS PRODUCTIVITY 1. Technology of multifunctional active hydrogenpulse action on the zone of drilling with fuel-oxidation mixtures containing high-energy components withhydroreactive action and catalyzers for decomposition of paraffin . The technology has been tested and applied in the wells of the East of Poltava, Bugrevatskogo, Tevlinsko-Russkinskoye, Kozievskogo and other fields. A big number of wells were put into operation fromthe inactivity. In Wells with marginal productivity, the production rate was increased from 2 to 27 times. Comparable performance results can be achieved only by using hydraulic board. However, it costs more than the proposed technology. And the cost of our procedure is completely paid off within 5-8 months of working of the repaired well.

  6. INCREASING OF WELLS PRODUCTIVITY 2. Limiting water penetration into wells with water repellent injection to the bottom-hole formation zone with subsequent elimination with alcohol-cement suspensions in partial jamming of oil and gas wells. Advanced technology, tested in several Russia's gas and oil fields and Ukraine. The use of this technology allows at the initial stage of the appearance of water to prevent flooding into the well and stabilize the hydrocarbon production without water.

  7. INCREASING OF WELLS PRODUCTIVITY WATER ISOLATION TECHNOLOGY • Technology allows you to: • create indestructible barrier by Crystal-forming impurities; • increase output of hydrocarbons by changing the surfactant properties of the rocks; • keep the duration of isolation – not less than 2-3 years.

  8. INCREASING OF WELLS PRODUCTIVITY WATER ISOLATION TECHNOLOGY Stages of technological process of water influx issolation in productive stratus 1 1-Lifting of the cone formation water in the zone of the perforation interval

  9. INCREASING OF WELLS PRODUCTIVITY WATER ISOLATION TECHNOLOGY Stages of technological process of water influx issolation in productive stratus 2 2 –injection of natural gas to displace water coning

  10. INCREASING OF WELLS PRODUCTIVITY WATER ISOLATION TECHNOLOGY Stages of technological process of water influx issolation in productive stratus 4 3 3-Injection of water isolation chemicals 4-Pushing the isolation chemicals with a high pressure gas injection.

  11. INCREASING OF WELLS PRODUCTIVITY WATER ISOLATION TECHNOLOGY Stages of technological process of water influx issolation in productive stratus 5 5-Created isolation barrier with a marble-like structure

  12. INCREASING OF WELLS PRODUCTIVITY 3. Reanimation of the bottom-hole area by the joint action of phosphorus-containing complex active chemicals and variable pressure in the well. Tested in the fields of Ukraine and Western Siberia. Proposed method in our last and improved version, allows to increase the productivity of wells in an average of 86% and is the most effective among all tested methods of chemical stimulation.

  13. INCREASING OF WELLS PRODUCTIVITY 4. Complex technology for killing, development and conservation of the wells in high-permeability reservoirs and reservoir with variables pressures using inverted dispersions (emulsions and suspensions) with density 550 ÷ 1450) kg/m3. Innovative technology , without analogues for gas wells. Used in many Russian, Ukranian and Kazajstan fields like Urengoĭand Yamburgskoye. This technology allows to increase the strength of the used microspheres and allows to re-use at least 10 times the lightweight chemical dispersions̆ and this way to bring the technical and economic parameters of the well repairing to the optimal indexes.

  14. INCREASING OF WELLS PRODUCTIVITY 5. Casing perforation of the productive layers using surface-activeand chemical active acidic systems with hydrocarbon basis with regulated density (490 - 2100 kg/m3) The casing perforation using hydrocarbon based surface-active chemicals increase the productivity of wells in an average 18%. Using our hydrocarbon based SAS in acid system we obtain an average incrementation of the well productivity around 65%.

  15. INCREASING OF WELLS PRODUCTIVITY 6. Liquidation of the flows between strings and gas flows into wells using low-viscosity reactive reagents or sealing polymer solutions on an organic basis. Used mainly for underground gas storage wells. The Cost-effectivity is significantly higher tan other methods.

  16. INCREASING OF WELLS PRODUCTIVITY 7. Drilling inverted suspension of microspheres for the opening of productive formations with anomalous formation pressure. Provide an effective blocking of the pore space of the well walls, prevents the absorption of liquids and deterioration of permeability and porosity parameters of the productive area. Depending on the drilling conditions they are divided into lightweight, which are used at low reservoir pressure and heavy weighted used in wells with high formation pressures.

  17. PROTECTION OF PIPELINES AND EQUIPMENT FROM CORROSSION 1. Chemical and electrochemical protection of pipelines and gas field equipmentfrom corrosion by using new generation corrosion inhibitors, conservation lubricants and protective coatings with vegetable oil base. This technology has been developed in our laboratory on a newly synthesized materials on vegetable oil base. On toxicological and environmental safety this materials exceed all existing analog materials on petrochemical base by 2.8 - 9.7 times, and on the protective effect - in 3-7 times, on the protection against corrosion and for longevity of use - in 1,6-6,0 times.

  18. OIL AND LUBRICANTS IN VEGETABLE BASE 1. New generation of oils and lubricants on vegetable oil base for reliable performance of compression systems of gas pumping stations. We have created a new generation of lubricants that have no analogues in the world practice. Their Toxicity - low toxic substance of the 4th class in dangerous substances classification, environmentally - from to 2 - 10 times less aggressive than the lubricants in the market, and their efficiency – is higher in 6-18 times.
