We propose that comparing the temperature records of relocated new meteorological stations to those of old meteorological stations is a better method for evaluating the urbanization contribution than the current methods. On the Web of Science and the China National Knowledge Infrastructure, previous studies on temperature records of paired old and relocated new meteorological stations were searched and selected. As a result, we gathered temperature data from 57 paired stations and discovered that the old stations' temperature was 0.66 ℃ higher than the new stations' (-0.90 to 1.63 ℃). The urbanization process may be responsible for more than 60% of the current temperature rise trends. Furthermore, there are strong correlations between periods of global warming and regional rapid urbanization, implying that rapid urbanization causes overestimation of global warming trends. Finally, the IPCC's assessment of global warming should be revised in the next report based on paired urban and rural temperature datasets from globally relocated meteorological stations.","PeriodicalId":355186,"journal":{"name":"Petroleum and Chemical Industry International","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131335130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Babalola","doi":"10.33140/pcii.05.01.09","DOIUrl":"https://doi.org/10.33140/pcii.05.01.09","url":null,"abstract":"Production enhancement from oil and gas fields is of key importance to operators. In order to achieve enhanced production, well stimulation techniques are often deployed to maximize recovery from oil and gas wells. Matrix acidizing is the most prominent technique deployed among other well stimulation techniques; considering its relatively lower cost, compared to hydraulic fracturing. Also of importance is the suitability of matrix acidizing to generate extra production and restore original productivity in wells that are damaged. Matrix acidization involves injection of an acid solution into the reservoir formation, at a pressure below the fracture pressure to dissolve some of the minerals within the rock with the key objective of removing damage near the wellbore, subsequently restoring the natural permeability and improving the well productivity. The standard acid treatments used in this work were HCl-HF (mud acid) formulations to dissolve the plugging minerals, mainly silicates (clays and feldspars). Experiments were carried out on sandstone samples that had been immersed in drilling fluid to allow cake formation and mud cake samples to evaluate the effectiveness of the formulated acids in well stimulation. Three standard mud acid concentrations were prepared, (13% HCl-3% HF, 17% HCl-5% HF and 24% HCl-6% HF).Results derived from the experiments indicated that the highest concentration of acid used (24% HCl-6% HF), gave a good result (8.05% of the original mass was dissolved). For the experiments involving the mud cake, the highest concentration of acid used (24% HCl-6% HF) gave a good result (94.86% of the original mass was dissolved). This showed that the higher concentration mud acid was a good candidate for skin removal in sandstone reservoirs, and wellbores that have been damaged by drilling fluid invasion.","PeriodicalId":355186,"journal":{"name":"Petroleum and Chemical Industry International","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128866356","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chemical systems produce chemical cells that take chemical compounds and move them into a cell, where they then react with another compound to produce a product that will then move outside the cell, while other compounds remain inside the cell. Cells connect to create multicellular organisms. Many different organisms are present at different levels. A few cells produce more complex structures, such as towers. A few towers may react to produce cities. Cites create a larger metropolis. Simple compounds are able to create unusually complex structures, such as machines that can switch between algorithms. Chemical systems may grow to infinity, forming incredible structures and behaviours. Every experiment was performed using two simple inorganic compounds. The duration of each experiment was minutes. The size of the chemical systems was usually measured in cm. We studied complex structures, behaviour’s, and level of “intelligence”.

This study aims to investigate sectoral interconnections and participation in the EPA that would facilitate further possible opportunities for the JapanAfrican businesses. The methodology employed is the Computable General Equilibrium model integrated with the Global Trade Analysis Project version 10A Multi-Region Input-Output database. We first modified the GTAP’s structure form to develop a long-run closure under steady-state and thereafter examined the African Continental Free Trade Area-Japan Economic Partnership Agreement (AfJEPA) with several EPAs scenarios relying on the quantitative comparison of economic impacts of different technical measurements. As a result, the AfJEPA can provide new possible opportunities for Africa-Japan businesses, such as contributing to the existing African and Japanese mega-regional trade agreements. Specifically, the electronics, petroleum and coal, and chemical, rubber, and plastic industries in Africa would see the highest percent growth. Likewise, the Japanese industries would improve their productivity in the motor vehicles and transport equipment, chemical, rubber, and plastic, and textiles and apparel industries. To sum up, trade facilitation and knowledge transfer, which policymakers can improve concrete action and investment, would considerably stimulate African and Japanese real GDP. Thus, potential growth would rely on deep regulation policy through a degree of openness and initial level of trade barriers to each country.","PeriodicalId":355186,"journal":{"name":"Petroleum and Chemical Industry International","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129856439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At a time when climate change, energy prices, energy poverty and environmental impacts are the focus of discussion and intervention in the other countries of the European Union, Portugal is managed by twelfths and without the possibility of changing public policies. The electoral decision will take place on 30 January 2022 and will then have a set of coalition negotiations, governance program adjustment and presentation of a new state budget for approval and discussion in specialty, and a long period is expected before real changes to the twelfth management system can be made. Among the various themes, the economic, social and environmental impacts of energy, especially oil and its replacement, of future decisions are unknown. Portugal has committed to achieving carbon neutrality by 2050 as a contribution to the global and European targets undertaken in the implementation of the Paris Agreement. Meeting this target requires a reduction in greenhouse gas emissions of more than 85% compared to 2005 emissions and a carbon sequestration capacity of 13 Mton. Decarbonisation is also an investment and job creation strategy. By 2030, Portugal is expected to reach a target of 47% renewable energy in gross final energy consumption and a 20% renewable energy target in transport. Accelerate the implementation of the National Energy and Climate Plan 2030 and the Roadmap for Carbon Neutrality 2050, promoting regional roadmaps for carbon neutrality, elaborating five-year carbon budgets that define a multi-year horizon, defining methodologies for assessing the legislative impact on climate action and eliminating administrative constraints that create disproportionate context costs without capital gains. Portugal has exceptional conditions to become an example of environmental sustainability vis-à-vis its European partners. Instead of using the environmental perspective as a weapon against economic development, the dimension of sustainability must be incorporated into the growth model itself. The specificity of Portugal, situated in the far west of Europe and with the Atlantic as its second frontier, makes the transatlantic relationship more important than for any other European country. Not ignoring the geopolitical forces centered on Asia and the Pacific, it is necessary to strengthen the Atlantic community, to deepen the relationship with the US and to strengthen the link to the countries of Latin America, to enhance Portugal's role in the point of access to Europe of goods and energy","PeriodicalId":355186,"journal":{"name":"Petroleum and Chemical Industry International","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114793146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
