Published: September 2024

Despite the fact that small rivers are called Small, their importance in terms of ecology is high. This is because the condition of large rivers will depend on smaller rivers. The degradation of small rivers negatively affects the state, is an important and urgent task. The purpose of the study was to geochemically analyze the composition of the waters of small rivers in the Syryms district and assess their quality. Water samples were taken from each river ecological state of medium and large rivers, because they feed at the expense of these small rivers. It is easy to see that every day the waters of these rivers are receding and the banks are expanding. Currently, one of the main tasks that environmental science sets for itself is to monitor the ecological state of water bodies. In connection with the conditions of increasing anthropogenic factors, determining the ecological state of small rivers plays an important role in maintaining the composition of the natural ecosystem. Small rivers are very sensitive to anthropogenic factors and react to these factors in the opposite way. The study of the chemical composition of small river waters, as well as their ecological state, is an important and urgent task. The aim of the study is a geochemical analysis of the composition of small river waters in the Syrymsky district and an assessment of their quality. Water samples were taken from each river to determine the composition of the water quality. The cameral stage was held in the laboratory of environmental and biogeochemical testing of M. Utemisov West Kazakhstan University. Chemical analysis was carried out using the widely used methods GOST 26449.1 — 85. After analyzing the indicators of water samples taken from the research area, it was found that the maximum raual concentration level did not exceed, except for the total hardness.

The concept of spirituality in V. Ptushkin’s compositional, particularly piano creativity: on the 75th anniversary of the Master
Authors: Rumiantseva A. 
Published: September 2024

The relevance of the article conditioned by the modern immediacy of the problem of maintenance of spiritual values, by the necessity of the research of regional features of composer’s schools and specifics of embodiment of spiritual instructions in V. Ptushkin’s compositional, particularly piano creativity, that hasn’t got an exhaustive coverage in modern national musicology.
The purpose of the article is to highlight the specifics of the concept of spirituality as the worldview and axiological center of V. Ptushkin’s compositional, particularly piano creativity.
The methodology of the article is based on comparative, historical-typological, interpretative method, methods of generalization, stylistic and genre analysis.
The results. The article highlights the concept of spirituality, represented as a concentrated reflection of the humanistic orientation of V. Ptushkin’s compositional, particularly piano creativity and a means of affirming spiritual values in a dialogue with the spiritual experience of mankind, appeals to the signs of cultural eras, genre model of the past — requiem, choral, spiritual cantata, concerto grosso, in the reproduction of eternally relevant images and themes — symbols of spirituality, in particular the image of Virgin Mary as the ideal of humanity’s existence and the positioning of the sublime and the earthly as the poles of worldview and human existence. It is revealed that the specificity of the embodiment of the concept of spirituality in the work for two pianos “The Sublime and the Earthly” is related to: understanding its significance through the prism of comparing personal and universal principles and allusions to the signs of the Renaissance, Classicism, romanticism; resonance with worldview guidelines of the culture of the border of XX–XXI centuries; functional mobility; the variability of performing teams; compositional and structural abnormality. The global significance of the concept of spirituality is imprinted in the work on the following levels: texture — in large-scale vertical chords, chronotope and dynamics — in powerful orchestral sonority, tonal organization — in the affirmation of major constructions, genre — in the movement from lyrical, individualized elegy to anthem as a reflection of the human unity.
The scientific novelty of the article is due to the substantiation of the concept of spirituality as a worldview basis of V. Ptushkin’s work and the study of the peculiarities of its embodiment, in particular in the play «The Sublime and the Earthly».
The practical significance of the article is determined by the possibility of using the results of the study in performing and pedagogical practice.
Prediction of shear wave velocity in three sedimentary rocks in East Baghdad oilfield using multiple regression analysis
Authors: Jawad Ali K. , Hadi Farqad A. 
Published: September 2024

Shear wave is a crucial parameter for assessing the wellbore stability, the stress response, and rock deformation. It is essential for constructing the mechanical earth model (MEM) for many applications related to reservoir geomechanics including wellbore stability, sand production, hydraulic fracturing, and fault reactivation. However, shear sonic data is often omitted during the well-logging measurements for cost and saving purposes. To overcome this challenge, recent research has been focused on determining shear wave velocity through the use of core plugs, empirical correlations, artificial intelligence techniques, and multiple regression to quantify and evaluate the mechanical properties of subsurface formations without performing direct measurements at the wellbore. The greatest difference between this study and the literature is to predict the shear wave velocities for three sedimentary rocks based on conventional well logs.
This study has been conducted on datasets of two wells drilled in the East Baghdad oilfield, for which there is a lack of shear wave data. Two formations (Tanuma and Zubair formations) within the production section of this field were conducted to develop new models for determining the shear wave velocity using multiple regression analysis. These two formations primarily consist of three lithologies: limestone, sandstone, and shale. Before the model development, data analysis on the selected data was applied to figure the most influential parameter(s) in determining the shear wave velocity. The results of the developed models are then compared with the previous models in the literature.
The results showed that the multiple regression analysis technique is a powerful technique in determining shear wave velocity with high-performance capacity. The correlation coefficient ( ) and the root mean square error (RMSE) were 0.84 and 0.092 for limestone, 0.84 and 0.0972 for sandstone, and 0.86 and 0.0796 for shale respectively. Furthermore, the performance of the developed models is well matched to the actual shear wave data rather than the Castagna correlations. The findings of this study are effective in determining shear wave velocity for future applications related to reservoir geomechanics without needing costly well-log or core measurements.

Published: September 2024

A successful synthesis of mesoporous Santa Barbara amorphous (SBA-15) with nanoparticle size was attempted using prepared sodium silicate from Iraqi high silica sand. EO20PO70EO20 copolymer was used as a template at highly acidic conditions (pH < 2). The effect of crystallization temperature of (100, 110, 120, and 130 0C), and crystallization time of (24, 48, 72, and 120 h) on surface properties was studied. The experiments were characterized using XRD, FTIR, AFM, BET, and FESEM. The XRD and FTIR tests represent amorphous SBA-15 without any impurities. Decreasing average particle size distribution increased the surface area, and decreased the porosity (pore volume, and pore size) in all experiments. The texture properties were surface area of 210-756 cm2/g, volume pore of 0.28-0.7 cm3/g, and pore size of 1.94-13.45 nm. The optimum result of surface area was achieved at hydrothermal conditions of 110 0C, and 24 h, while optimum results of pore volume, and pore size were achieved at hydrothermal conditions of 100 0C, and 120 h. Semi-spherical shape of particles appeared at hydrothermal conditions of 120 0C and 24 h. This morphology was transferred to small rods at 130 0C, and to semi-platelets at 120 h.

Published: September 2024

In this study, lead ions were removed from simulated wastewater by batch adsorptive filtration. A three-dimensional printed water filtration was designed using a blender and successfully synthesized from a PLA spool and a 3d printer machine. The filter surface was treated with NaOH solution to hydrolyze the polyester group in PLA. After that, α-Fe2O3 was prepared by the coprecipitation method and coated on the filter through doping and drying. α-Fe2O3 was characterized by X-ray diffraction (XRD), Energy-dispersive X-ray spectroscopy (EDX), and Brunauer-Emmet-teller (BET). The results successfully indicate the synthesis of α-Fe2O3 consisting of 67.3% Fe and 32.7% O2. α-Fe2O3 appeared to have a surface area of 95 m²/g with distinct morphology and functional group. The effect of initial Pb concentration (100-800) ppm and the effect of contact time (5-120) min on the removal process were studied. Lab data was collected, and the adsorption was investigated kinetically. The 3d printed filter system coated by iron oxide showed significant and promised results for wastewater treatment and lead ions removal using this technique. Also, the results showed that the adsorption of Pb ions on the α-Fe2O3 surface fitted with the Langmuir model, with a correlation coefficient (R²) of 98.65%. The kinetic model’s investigations revealed that the pseudo-second-order model was the most fitted model for the process with R² of 99.997%. The highest adsorption saturation capacity was 165.2 mg/g adsorbent.
Analytical and descriptive study of the production behavior for pilot multi-stages hydraulic fracturing wells in southeast Iraq
Authors: Hashim Ameer H. , Al-Jawad Mohammed S. 
Published: September 2024

The hydraulic fracturing technique is a widely used technique worldwide, making it interesting to study. This technique was applied for the first time in Iraq on a tight carbonate reservoir in the Halfaya oil field. In this field, the oil production rates, and flowing pressure were low during production periods reflecting a problem for the development plan designed to increase production using a hydraulic fracture technique. Initially, the hydraulic fracture well showed high oil-producing rates, but then, quickly experienced a high decline failing to keep a stable production rate. To address this problem, it is important to describe and analyze the behavior of pilot hydraulic fracturing wells during their production period, study the inflow performance relationship (IPR), and determine the optimum wellhead pressure above the bubble point pressure (Pb) to avoid loss of lifting energy. Furthermore, it identifies the allowable flow rate to keep stable production, investigates the effect of selecting internal tubing size, and reveals a future production procedure for hydraulic fracture wells.
This study reveals that the transient inflow performance relationship observed in the production history of hydraulic fracture well in the tight carbonate reservoir and traditional inflow performance relationship concepts are not applicable. The optimum wellhead pressure for stability in production for Wells w-5 and w-55 is determined to be 750 and 580 psi with optimum rates of 800 and 450 Bbl/D, respectively. The results also showed that producing at a high flow rate may cause a depletion in the fracture potential storage without giving an opportunity for a reservoir to compensate for the produced fluid into fracturing potential storage. The internal tubing size has a passive effect on the hydraulic fracture well, as an increase in size causes an unstable flow zone. Lastly, future production procedures emphasize keeping wellhead pressures stable or increasing them if they drop. This can be accomplished by re-adjusting the choke size according to any changes observed.
