“…Zhantayev et al [12] also used the persistent scatterers interferometry technique for urban subsidence monitoring in the Republic of Kazakhstan. These studies [12] applied COSMO-SkyMed 2011-2013 for Nur-Sultan City and ENVISAT ASAR 2003-2006 radar satellite images for Almaty City. InSAR was also used for other oil and gas fields and mining sites in Kazakhstan like the the Karazhanbas oilfield, etc.…”

This research focused on the quantitative assessment of the surface deformation velocities and rates and their natural and man-made controlling factors at Tengiz Oilfield in Kazakhstan using the Small Baseline Subset remote sensing technique followed by 3D and 2D decompositions and cosine corrections to derive vertical and horizontal movements from line-of-sight (LOS) measurements. In the present research we applied time-series of Sentinel-1 satellite images acquired during 2018–2020. All ground deformation derivatives showed the continuous subsidence at the Tengiz oilfield with increasing velocity. 3D and 2D decompositions of LOS measurements to vertical movement showed that the Tengiz Oil Field 2018–2020 continuously subsided with the maximum annual vertical deformation velocity around 70 mm. Based on the LOS measurements, the maximum annual subsiding velocity was observed to be 60 mm. Cosine corrections of LOS measurements to vertical movement, however, revealed a maximum annual vertical deformation velocity of 77 mm. The vertical deformation confirmed typical patterns of subsidence caused by oil extraction. Detected east-west and north-south horizontal movements at the Tengiz field clearly indicated that the study area crossed by seismic faults is affected by natural tectonic processes. The overall RMSE of 3D decomposed vertical deformation in relationship to LOS measurements and cosine corrections were in the range of 10–13 mm and 6–8 mm, correspondingly. The results of the present research will support operators of oil and gas fields and also other types of infrastructure to evaluate the actual differences of InSAR ground deformation measurements against the required standards and the precision of measurements depending on the operational needs, timeframes and availability of radar imagery.

“…The geospatial information obtained in this way allows us to establish the spectral images of objects due to the deep migration of hydrocarbon fluids and heat and mass transfer of deep matter, leading to changes in soils, soils, and vegetation located on the surface of the study area. The integral effect of these factors is expressed in anomalies associated with both a change in the stress-strain state of the earth's crust and fluid-geodynamic processes, which are detected in space images [11,12].…”

This article contains the first obtained results of measuring the latitudinal variations of the very weak ammonia (NH3) absorption band at 552 nm along the central Jupiter meridian based on spectral observations in 2019. This study is preliminary in nature as the first attempt to clarify the possibility and advisability of further detailed study of this weak ammonia band behavior on the Jupiter disk. We obtained the latitude variations of the equivalent widths and equivalent absorption paths for the 552 nm NH3 band and, for comparison, the same characteristics for the more intense, but also weak NH3 645 nm band. The absorption maximum in both bands is observed in the equatorial zone, where in the center of the disk their equivalent widths are: W (552 nm) = 2.58 ± 0.29 A and W (645 nm) = 6.77 ± 0.25 A. A feature that distinguishes the behavior of the 552 nm NH3 band from the 645 nm NH3 band is a steeper decrease in absorption towards high latitudes, as well as small differences in the positions of absorption extrema in latitudes. The effect of latitudinal differences in the position of the extrema of the methane absorption bands was discovered by us as early as 1999 observations and was later noted also in the ammonia absorption bands. These features reflect structural differences in the Jupiter cloud layer and its troposphere and can serve as one of the means for its (troposphere) optical sounding.

Бұл мақалада уранды жерасты шаймалау әдісі арқылы өндіруді модельдеу есептеулерін MPI параллельдеу технологиясын пайдалану арқылы жүзеге асырылды. MPI технологиясы ғылыми есептеулерде белсенді қолданылады және процесстерді ішкі облыстарға бөлуінің арқасында есептеулерді тездетуге мүмкіндік береді. Есептеудің бастапқы облысы әр жеке процесске арналған ішкі облыстарға бөлініп, барлық процесстердің синхронды жұмыс жасауы үшін әр облыс бірдей нүкте санына бөлінді. Параллель есептеулер алгоритмі әртүрлі процесс сандарын іске қосулармен тексерілді. Бастапқы облыстағы нүктелер саны 360×180×180 құрады. Процесс саны өскен сайын, оған бөлінген нүктелер саны азаяды, яғни есептеу уақытын азайтуға мүмкіндік береді. Жерасты шаймалау технологиясы - бұл ұңғымалар арқылы қабаттарға сілтісіздендіру ерітіндісін айдау және сілтісіздендіру ерітіндісінің кенмен химиялық өзара әрекеттесуі арқылы тау жынысы ішіндегі минералды селективті еріту әдісі. Жерасты шаймалау әдісі тұз, калий, күкірт сияқты әртүрлі қатты заттарды бөліп алуға қолданылатын ерітінді негізінде өндіруші әдістер тобына жатады. Кен қабатын еріткішпен қышқылдандыру, кен денесіндегі сорылатын қышқыл ерітіндісін фильтрациялау және өнімді ерітіндіні сору процестерін қарастырып, реагенттің, сұйық және қатты фазадағы пайдалы компонент концентрацияларының таралулары анықталды.
