Reservoir modelling and production forecasting are critical inputs in this scenario for effective management. The spatial distribution of reservoir properties describing the reservoir and associated output profiles is difficult to estimate since naturally occurring reservoirs are extremely heterogeneous and nonlinear in nature. In terms of reservoir properties and history matching, an accurate model constructed with the aid of data obtained from the reservoir, can lead to more effective reservoir management, and such models can be created using mathematical modelling and optimization techniques. This chapter covers a variety of optimization strategies that can be used for output forecasting and background matching. Simulated Annealing (SA), Scatter Search (SS), Neighborhood algorithm (NA), Particle Swarm Optimization (PSO), and Ant Colony Optimization are examples of gradient-based and non-gradient-based optimization techniques (ACO), The application of Ensemble Kalman Filters (EnKF) and Genetic Algorithms (GA) to reservoir output history matching and efficiency. The chapter also goes into recent developments and adaptations of these techniques.

Prediction of Pressure Gradients for Multiphase Flow in Pipes https://journalgazett.com/prediction-of-pressure-gradients-for-multiphase-flow-in-pipes/ https://journalgazett.com/prediction-of-pressure-gradients-for-multiphase-flow-in-pipes/#respond Thu, 06 May 2021 04:29:12 +0000 https://journalgazett.com/?p=10789 Owing to the varying flow rates of the different phases, pressure traverse in multiphase flow varies from single phase flow. The majority of multiphase flow pressure traverse correlations are designed for vertical wells, but the Beggs and Brill model is one of the few that is used for inclined pipes. The aim of the project is to demonstrate how the model can be improved. This project is focused on research into multiphase fluid flow in pipes of any inclination, with an emphasis on the Beggs and Brill flow model. The Beggs and Brill and Beggs and Brill Traverse models were compared in two cases: liquid holdup correction and differences in the Gas Liquid Ratio (GLR). Pressure gradient forecasts are far from reliable as compared to measured data in the field due to the observational existence of the Beggs and Brill model. The aim of this project is to reduce the error margin between expected and measured pressure gradient values. The Beggs and Brill Traverse Model was found to be a better prediction method than the Beggs and Brill model for the same reservoir, fluid, and pipe properties. For GLR above 400 scf/stb, prediction errors increased with pipe length, whereas they were more reliable for pipes between 12,000 and 17,000 ft and pressures between 3,000 and 4,500 psi. The Beggs and Brill Traverse Model, on the other hand, is constrained by the correlations used to compute fluid properties. In order to effectively design tubing and optimal production strategies, it is important to predict pressure drop in vertical multiphase flow.

Research on Dry Matter Production, Nutrient Cycled and Removed as Well as Soil Fertility Changes in Yam-Based Cropping Systems with Herbaceous Legumes in the Guinea-Sudan Zone of Benin https://journalgazett.com/research-on-dry-matter-production-nutrient-cycled-and-removed-as-well-as-soil-fertility-changes-in-yam-based-cropping-systems-with-herbaceous-legumes-in-the-guinea-sudan-zone-of-benin/ https://journalgazett.com/research-on-dry-matter-production-nutrient-cycled-and-removed-as-well-as-soil-fertility-changes-in-yam-based-cropping-systems-with-herbaceous-legumes-in-the-guinea-sudan-zone-of-benin/#respond Thu, 06 May 2021 04:28:39 +0000 https://journalgazett.com/?p=10787 Deforestation and soil nutrient degradation are common outcomes of traditional yam-based cropping systems (shifting cultivation, slash-and-burn, and short fallow). The aim of this research was to see how yam-based systems with herbaceous legumes affected dry matter (DM) production (tubers, shoots), nutrient removal and recycling, and soil fertility changes. Traditional smallholder systems (1-year fallow of Andropogon gayanus-yam rotation, maize-yam rotation) were compared to yam-based systems with herbaceous legumes (Aeschynomene histrix/maize intercropping-yam rotation, Mucuna pruriens/maize intercropping-yam rotation). The experiment was performed with 32 farmers, eight in each location, during the cropping seasons of 2002 and 2004. A partial nested model with five factors: Year, Replication, Farmer, Site, and Treatment was used to conduct a randomised full block design with four treatments and four replicates for each of them. Dry matter (DM) output (tubers, shoots), nutrient contribution to the systems, and soil properties were studied using analysis of variance (ANOVA) and the general linear model (GLM) procedure at depths of 0–10 and 10–20 cm. In contrast to conventional systems, yam-based systems with legumes greatly improved DM removal and recycling, complete N, P, and K recycling or removal, and soil chemical properties (SOM, N, P, K, and pH water). Interactions between treatment, farmer, and year treatment affected yam tuber dry matter development significantly. In yam-based systems with legumes, the amounts of N, P, and K recycled in the yam shoot were substantially higher than in conventional systems.

Integrated Weed Management in Ginger (Zingiber officinale) for Higher Productivity in Plains of Assam https://journalgazett.com/integrated-weed-management-in-ginger-zingiber-officinale-for-higher-productivity-in-plains-of-assam/ https://journalgazett.com/integrated-weed-management-in-ginger-zingiber-officinale-for-higher-productivity-in-plains-of-assam/#respond Thu, 06 May 2021 04:22:58 +0000 https://journalgazett.com/?p=10785 During 2014-15 and 2015-16, a field experiment was conducted at the Assam Agricultural University’s Instruction-cum-Research Farm in Jorhat district, Assam, India, to identify a suitable combination of ginger and cowpea intercropping, as well as various weed management practises, to effectively manage weeds in ginger. Since it is a widely spaced and long-lasting crop, growers have plenty of opportunities to use the available vacant space throughout the rhizome’s early growth stage to plant any short-term leguminous intercrop. Four legume intercropping systems and four weed control practises were considered in a total of 16 treatment combinations. Legume crop intercropping Cowpea planted between rows of Ginger and incorporated at 40 days after sowing (DAS) or between alternate rows of Ginger and incorporated at 40 days after sowing (DAS) and pre-emergence application of Metribuzin 500 g ai ha-1 + hand weeding (HW) at 70, 100, and 140 days after planting (DAP) produced better ginger growth and rhizome yield.

Manually Operated Onion Bulblet Planter over a Traditional Method of Planting: A Comparative Study https://journalgazett.com/manually-operated-onion-bulblet-planter-over-a-traditional-method-of-planting-a-comparative-study/ https://journalgazett.com/manually-operated-onion-bulblet-planter-over-a-traditional-method-of-planting-a-comparative-study/#respond Thu, 06 May 2021 04:22:21 +0000 https://journalgazett.com/?p=10783 In the college of Agricultural Engineering JNKVV Jabalpur, a study was conducted to compare the planting of onions using a manually operated onion bulblet planter versus the hand planting process (Traditional method of planting). An inclined plate metering unit was used to create a manually operated onion bulblet planter. The established planter’s output was assessed in terms of field efficiency and the percentage of missing hills. It also compares the cost and time required to operate an established planter to hand planting. The results showed that with a chisel style furrow opener, the field efficiency was 83.33 percent and the missing index percentage was 2.22 percent. It was discovered that manually operating an onion bulblet planter cost Rs. 1790. 81 per hectare of land, compared to 65 man days and Rs. 9300 for one hectare of land using the hand planting process. When compared to the conventional method of planting, the planter can save time and labour.

Research on Real Time Implementation of Fuzzy Based Buck Boost Converter Using LabVIEW https://journalgazett.com/research-on-real-time-implementation-of-fuzzy-based-buck-boost-converter-using-labview/ https://journalgazett.com/research-on-real-time-implementation-of-fuzzy-based-buck-boost-converter-using-labview/#respond Thu, 06 May 2021 04:21:31 +0000 https://journalgazett.com/?p=10781 Virtual instrumentation is characterised as the use of industry-standard computer technology to construct user-defined instrumentation systems by combining measurement and control hardware and software. Using LabVIEW, this paper proposes a two-input fuzzy logic controller (FLC) for buck boost converter output-voltage regulation. As two inputs to the controller, the output voltage has been used as a closed loop feedback to evaluate the output error (e) and the shift in error (e). The inductance and capacitor in the buck boost converter were chosen to ensure continuous operating mode (CCM) and low output voltage ripple. The FLC has a strong output voltage response when compared to the PID controller response, according to the experimental results. This study successfully demonstrated that LabVIEW and Fuzzy Logic controllers can be used to create a method for selecting controller modes.

Study on Reading and Writing Abilities of Thai and Migrant Students on the Use of Phonics Method https://journalgazett.com/study-on-reading-and-writing-abilities-of-thai-and-migrant-students-on-the-use-of-phonics-method/ https://journalgazett.com/study-on-reading-and-writing-abilities-of-thai-and-migrant-students-on-the-use-of-phonics-method/#respond Thu, 06 May 2021 04:20:52 +0000 https://journalgazett.com/?p=10779 Using the phonics approach, this study looked at the reading and writing abilities of Thai and immigrant students. The students in this study were from Wat Sirimongkol School in Samut Sakorn Province, and they were in Grade 1 Thai and immigrant students. Purposive sampling was used to pick the students who were sampled. Pre- and post-test reading and writing skill assessment forms were used as testing methods in this report. Multivariate analysis of variance, or MANOVA, was used to interpret the collected data. The study discovered that Grade 1 Thai and migrant students who had received Phonics training performed better on the first and second post-tests than on the pre-tests, with a statistical significance of.01. The phonics approach allows students to practise reading and writing from beginning to end, giving them more opportunities to rehearse of sound and practise reading and writing, and thus has a huge positive effect on their learning.

The Bioterrorist Attacks on America: A Historical Review https://journalgazett.com/the-bioterrorist-attacks-on-america-a-historical-review/ https://journalgazett.com/the-bioterrorist-attacks-on-america-a-historical-review/#respond Thu, 06 May 2021 04:19:44 +0000 https://journalgazett.com/?p=10777 The events surrounding the 9/11 bioterrorist attacks on US civilians, which used anthrax spores, are discussed in this article. The points raised in this article substantiate the flaws in the hunt for “domestic” terrorists, suggesting that Arab agents were involved in the coordinated attacks by sending anthrax spore-laced letters. Since the attacks used a weaponized aerosol version of anthrax, there is suspicion that the spores were manufactured in a nation capable of producing bacteriological arms. Representatives from special interest groups presented the findings of an inquiry into the origins of biological weapons, stating that the operation’s participants had been identified. Finally, this article makes valid points for which further research is essential.

The Linear Chain Clusters in Real Gases https://journalgazett.com/the-linear-chain-clusters-in-real-gases/ https://journalgazett.com/the-linear-chain-clusters-in-real-gases/#respond Thu, 06 May 2021 04:15:54 +0000 https://journalgazett.com/?p=10775 The author’s new class of linear chain clusters is described in this chapter, as well as the methods for evaluating their properties. There are two types of clusters in real gases: linear clusters with a small number of bonds between particles and closely bound two and three dimensional clusters. For several pure gases, the experimental data analysis reveals large temperature and density zones dominated by linear chain clusters. At moderate densities of real gases, expanding the possible energy density sequence by the monomer fraction density yields cluster bond parameters and their equilibrium constants, which can be attributed to this new class of clusters. The computer-aided study of precise thermophysical data for pure fluids using monomer fraction density reveals wonderful properties of these unknown cluster structures in real gases. Extrapolating the properties of these loosely bound clusters to higher densities yields a variety of tightly bound three-dimensional clusters in sub- and supercritical fluids in general, and particularly in CO2. It’s crucial to understand the structure and parameters of the clusters in this gas, which is commonly used in supercritical fluid technologies. The properties of massive three-dimensional clusters of numbers n of particles up to the level of one thousand are discovered by moving from diluted to dense gases step by step. The soft structural transition between dominating cluster fractions with neighbour numbers n and between gas-like and liquid-like supercritical fluids is studied using a logarithmic method to estimate the averaged numbers n of particles in three-dimensional clusters.

Recent Development and Studies: The Consciousness’ Forming by Fractal Education and the Problem of Divinity https://journalgazett.com/recent-development-and-studies-the-consciousness-forming-by-fractal-education-and-the-problem-of-divinity/ https://journalgazett.com/recent-development-and-studies-the-consciousness-forming-by-fractal-education-and-the-problem-of-divinity/#respond Thu, 06 May 2021 04:15:14 +0000 https://journalgazett.com/?p=10773 The paper examines how a person or collective consciousness can achieve a ‘grace level’ (haric level) that is close to the highest possible, as measured by the Divinity. The analysis’ first conclusion is that fractal, networked education, which is obtained from simple to complex and from an individual to a larger group of (of group) consciences, through which the learning of an individual superior consciousness, in particular – teacher, professor, is transmitted to those spiritually guided by transmitting not only his teaching but also his attitude toward the and the formation of individual and fractal consciences of haric level – understood as the highest value level of the psycho-social Good – necessitates a strategy of using the obtained orthodox-scientific teaching, based on the completion of the fundamental principles of orthodoxy: purification, enlightenment, union with the Divinity, fight against evil, with the sc Another inference is that the presence of a divine haric meta-consciousness is possible. The capacity of a single psycho-bio-social entity, understood in the sense of a haric spiritual leader of many haric super-consciences, which are spiritual leaders of a significant number of superior consciences relative to the average level, exceeds that of a single psycho-bio-social entity, resulting in a God with super-normal powers, capable of restoring the Good of the orthodox-scientific kind in the world, will exist more as a judiciator. which includes the orthodox reciprocity principle. It follows that the possibility of Godness’ spiritual leadership of mankind requires energo-informational intervention through advanced technological means such as telepathic amplifiers, which could also explain the transmission of the Holy Spirit and some recorded paranormal phenomena such as “intelligent ghost” cases. As a result, scientific orthodoxy can disqualify God, and the principles of Providence must be changed to include orthodox-scientific collaboration with the Creation, orthodox-scientific leadership of the Creation, and orthodox-scientific protection of the Creation.
