MORE EFFICINET OIL AND GAS RECOVERY METHOD

17 April 2020 127

Project introduced by REC "Sustainable subsurface management" together with Engineering Academy of the RUDN University is one of the best among R&D and pilot-plan projects presented during the competition organized by RUDN University in the framework with Russian and foreign tech firms collaboration.

The main aim of the competition is to draw attention of the scientists in order to find out the real world experience of the Russian and foreign business. The leading companies are making tasks, which must be solved by research groups.

The project described above meets the interest of the Reservoir Surveillance Services, servicing company in oil and gas industry of Kazakhstan. The main idea of the project is first to research and after to apply the technology for enhancing oil recovery by water-gas stimulation of formation.

Water-gas stimulation is a method for enhancing the oil recovery by inputting the oil-well gas produced at the same place into the oil formation mixed with the water. The mixture decreases the capillary forces, which holds back oil in reservoir and decreases the oil viscosity index that makes the oil recovery process more efficient.

Water-gas stimulation is one of the promising areas devoted to the oil recovery increasing index, because along with the high efficiency one solves the environmental task about associate gas utilization and it means that there is no need to flare it.

Currently, there is a number of water-gas technologies involving the combined and alternate injection of water and gas, and also differ in the use of pumps, compressors, boosters or ejectors to pump the mixture into the well. Each technology works differently depending on the viscosity of the oil and the characteristics of the field. The joint project of the REC "Sustainable subsurface management" and Engineering Academy of the RUDN University will help to form the optimal set of technologies for the fields of a Kazakhstan company.

Russian oil recovery technology is water flooding technology that is not efficient for oil recovery and key point is that such method makes it difficult to use the formation for further oil production. The research of the REC "Sustainable subsurface management" and Engineering Academy of the RUDN University will help to improve the technologies used by the local oil and gas companies.

TECHNOLOGY OF PNRPU SCIENTISTS WILL RESTORE VALUABLE ELEMENTS FROM PRODUCTION WASTE

Now more and more attention is paid to the process of restoration of nitrogen and phosphorus from industrial and agricultural waste. This is connected with the need to implement the concept of sustainable development of society, based on the circular economy. These elements are biogenic, vital for plant growth. Phosphorus reserves are limited, and the process of obtaining nitrogen is energy-consuming. Potential sources of secondary raw materials are water waste from many industries: the fertilizer industry, pharmaceutical products, semiconductor production and agriculture. The recycling of nitrogen and phosphorus allows not only to reduce the consumption of non-renewable mineral resources, but also to reduce the saturation of natural water bodies with biogenic elements, the excess of which leads to swamping of water bodies and to a decrease in the amount of drinking water. To solve this problem, PNRPU scientists have developed a new approach that has increased the efficiency of extracting ammonium (a form of nitrogen) and phosphate (a form of phosphorus) from industrial waste water to 98-99%. The traditional method does not achieve such results. Moreover, the technology of Perm scientists will make it possible to produce domestically produced long-acting fertilizer based on struvite (a phosphate mineral) and will contribute to the import substitution of foreign analogues.

THE MODEL CREATED BY PNRPU SCIENTISTS WILL PREDICT DEFECTS IN LASER POWDER SURFACING

The method of laser powder surfacing is used to restore worn-out or damaged metal parts. A powerful fiber laser creates a molten weld pool, and then metal powder is automatically fed into it. A common problem that occurs in this process is the deformation of the part, being repaired, under the action of internal stresses. This leads to a defect called warping. One of the aims of developing a technological process for the repair of parts by laser powder surfacing is the prediction of warping defects. The determination of the optimal defect-free surfacing mode for specific parts experimentally is unprofitable due to high financial and time costs and often even impossible. The researchers of the PNRPU together with JSC “UEC-Aviadvigatel” developed a mathematical model for calculating warping during laser powder surfacing to solve this problem. The scientists were able to predict with high accuracy the behavior of the part during the surfacing process thanks to numerical simulations. In the future, the development will help in choosing the optimal set of parameters for repairing parts with the most complicated parts.
