3. Project of commercialization of technologies of the Ministry of Education and Science of the Republic of Kazakhstan and the World Bank (2012-2014) “Development and implementation of polymer flooding technology to increase oil recovery“.
Research supervisor: Professor S. E. Kudaibergenov.
Project goal: Development and subsequent commercialization of polymer flooding technology to increase oil recovery in Kazakhstan’s oil fields.
Results: The technology of polymer flooding for increasing oil recovery has been developed. The proposed technology leads to a decrease in the permeability of the flooded filtration channels, a redistribution of filtration flows, an increase in the coverage of the reservoir by flooding and, as a result, an increase in oil flow rates from neighboring producing wells. The formation of a solid gel structure in reservoir water with high mineralization leads to blockage of the pore space and redistribution of filtration flows. 234 and 160 cubic meters of polymer solution in the concentration range 0.2-1.0% were injected into injection wells No. 3383 and No. 3065 of the Kumkol field. According to the results of the OPI for the period from October 1, 2013 to September 1, 2014 (for 11 months), the amount of additional oil produced from 6 producing wells amounted to 5890 tons. Within the framework of the proposed technology, the consumption of the polymer reagent for the extraction of 1 ton of oil is 10-50 times less than the current technologies of gel-polymer flooding.
4. Project of commercialization of technologies of the Ministry of Education and Science of the Republic of Kazakhstan and the World Bank (2013-2014) Grant program for senior and junior researchers 2013 “Development of composite hydrogel scrapers for cleaning the internal cavity of oil pipelines“.
Research supervisor: Sadakbayeva Zh. K.
Project goal: development of technology for the production of composite hydrogel “scrapers” with specified properties for cleaning the internal cavity of main oil pipelines, gas pipelines and water pipelines of different diameters and complex profiles from mechanical impurities, asphalt-resin-paraffin deposits (AFS), corrosion products, gas and water-salt accumulations.
Results: Composite gels based on polyacrylamide and clay minerals were tested on a model oil pipeline under conditions close to real conditions. The principal possibility of using composite hydrogels for cleaning the internal cavity of main oil and gas pipelines of different diameters and complex profiles from mechanical impurities, ASPO and water-salt accumulations is shown. The method of scaling the synthesis of composite hydrogel scrapers, the scheme of the installation for the synthesis, as well as the scheme of the temporary chamber for launching the scraper is developed. The technological regulations for testing scrapers in experimental-industrial conditions have been prepared. In 2015, the Industrial Development and Industrial Safety Committee of the Ministry of Investment and Development of the Republic of Kazakhstan issued a permit for the production and use of PIG-1 hydrogel scrapers for cleaning oil pipelines.
5. Joint Project with Xingjian University, Urumqi “DEVELOPMENT OF COMPOSITE HYDROGEL “PIGS” FOR CLEANING OF INTERNAL SURFACE OF PIPELINES” (2015-2016).
Principal Investigators: Prof. Shimei Xu, Prof. S. Kudaibergenov.
Project summary. The proposed project targets at development of the technology for fabrication of composite hydrogel “pigs” with desired properties, to be applied for cleaning the inner chambers of the varied diameter and complex shape oil-truck pipelines from the debris, mechanical impurities, sand, asphaltene-tar-paraffin deposites (ATPD) and water-saline accumulations. The scientific novelty of the topic consists of development of fundamental basics of composite hydrogel materials fabrication via immobilization of inorganic nano- and microparticles within hydrogel matrix by in situ (single-stage) polymerization. Being flexible and mechanically strong, unlike mechanical analogues, hydrogel “pigs” can freely pass through the pipelines of various shape and size, allow good hydraulic seal with the inner pipeline surface, provide explosion and fire safety, and absorb water when moving along the pipeline; they can be introduced into the pipeline without standard inlet-outlet “pig” chambers. The project originality arises from the suggested technology simplicity, low price and availability of the starting materials, and versatility of the composites (they can be used for oil and petrochemical products transporting as well as anti-corrosion treatment of the inner pipeline surfaces before operation). Periodic treatment of the pipelines with the hydrogel “pig” will significantly increase their efficiency, prevent their corrosion, and prolong the operation time.
6. No.3397/GF4 of the SC of the Ministry of Education and Science of the Republic of Kazakhstan (2015-2018) “Development of technology for obtaining hydrophobic-modified polymer additives for inhibiting paraffin deposition and reducing the temperature of oil flow loss“.
Research supervisor: Professor S. E. Kudaibergenov.
Project goal: Development of hydrophobic modified polymers to prevent paraffin deposition processes and reduce the flow loss temperature of high-viscosity and high-paraffin oils of Kazakhstan stored in tanks and transported through oilfield and main pipelines.
Results: Pilot tests of depressant additives based on hydrophobically modified polymers as inhibitors of the deposition of AFS of crude oil from the Kumkol field were carried out in cooperation with the STC of KazTransOil JSC on a model oil pipeline. The depressor efficiency of additives was determined, the effect of additives on changes in rheological parameters was studied, and the high efficiency of additives for inhibiting the formation of AFS was shown. when the polymer additive KRO-2 (active concentration 500 ppm) is added to the oil, the amount of released ASPs is 1 g. While in the absence of a polymer additive, 56.2 g of ASPO is deposited in the inner wall of the model oil pipeline. This indicates a high efficiency of inhibition of AFS by polymer additives. The developed samples of depressants based on hydrophobically modified polymers in combination with an industrially used additive based on an ethylene and vinyl acetate (EVA) copolymer are highly effective against the oil of the Mangyshlak field and the Buzchi-Mangyshlak oil mixture, which leads to a decrease in the flow loss temperature of the model oil mixture to -12 and-150C. When using combined depressant additives for the Buzachi-Mangyshlak oil mixture, the efficiency of inhibition of ASPO reaches 99-100%. The certificate of testing of depressant additives of the KRO series together with STC “KazTransOil”was received.

Research supervisor: Professor V. B. Sigitov.
Project objective: To develop formulations of drilling fluids (BR) based on some polysaccharides that are prone to flocculation and self-organization in water-salt environments, for drilling in complicated mining and geological conditions.
Results: on the basis of a mixture of gellan, starch and xanthan, the formulations of seven new clay-free and low-clay BRS were developed. Experimental and industrial tests (OPI) of a new drilling mud were conducted during the drilling of the ore zone, which showed its high performance characteristics. Based on the results of the OPI, the technological regulations for the use of drilling mud were prepared.

11. IRN: AR08855552. SC MES RK (2021-2023) Synthesis and research of thermo-and salt-sensitive polyampholytic nano-and microgels.
Research supervisor: prof. Kudaibergenov S. E.
Project aim. Synthesis and research of thermo-and salt-sensitive polyampholytic nano-and microgels in combination with hydrophobic/hydrophilic monomers for potential use in medicine and oil production.
Results in 2020: A triple phase diagram is constructed consisting of a mixture of organic solvents (toluene-pentanol), a surfactant (sodium dodecyl sulfate, DDSN), water, or a mixture of monomers (the sodium salt of 2-acrylamido-2-methyl-1-propanesulfonic acid, APMSN, and (3-acrylamidopropyl) trimethylammonium chloride, APTACH). The sizes of dispersed particles in the microemulsion composition were determined by the method of dynamic laser light scattering. It is shown that the size of the dispersed medium in the case of an AMPSN solution is from 4 to 11 nm, depending on the total concentration of the aqueous phase in the system. For a system with APTAH, the size of dispersed particles is 4-5 nm. In this case, the microemulsion is destabilized due to the interaction of positively charged monomers with negatively charged DDSN molecules. For the compositions APTAH 25–AMPSN 75 and APTAH 50–AMPSN 50, the sizes of dispersed particles are 4-11 nm. Polyampholytic nano-and microgels based on APTAH and AMPSN were synthesized under conditions of inversion microemulsion polymerization. Radical polymerization of AMPSN and APTAH of three compositions (75: 25, 50:50 and 25:75 mol. %) in microemulsions of the “water in oil” type in the presence of a crosslinking agent N, N-methylene bisacrylamide (MBAA), and polyampholite nanogels were obtained. The average hydrodynamic dimensions and morphology of hydrogel nano-and microgels, which in the initial state are from 4 to 12 nm, and in the swollen state-40-80 nm due to water adsorption, are determined.
