Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.
Technology Reports of Kansai University (ISSN: 04532198) is a peer-reviewed journal. The journal covers all sort of engineering topic as well as mathematics and physics. the journal's scopes are
in the following fields but not limited to:
Permeability is the most essential parameter in reservoir characterization, reservoir management, and forecast the future performance of the reservoir. Permeability is directly measured from core routine analysis and well testing, these techniques are of highly costs; for that reason, a correlation is to be generated in order to estimate permeability in un-cored wells. Cross plot shows that Mishrif reservoir consists mainly of limestone with an amount of sand and little shale. Plot of permeability versus porosity for well Amarah-5, show a (correlation coefficient) of (0.6767) by using best fit line. The flow zone indicator method shows that Mishrif formation consists of eight units of flow (hydraulic units), and the obtained regression was with correlation coefficient between (0.872 - 0.994). By using Grace Program (Alternative Conditional Expectation) to generate a correlation, using normal logarthim of gamma ray, and neutron porosity as independent parameters, which gives correlation coefficient of 0.809. The flow zone indicator correlation is the best regression to estimate permeability; because the reservoir is divided into multiple units which reduce heterogeneity
Screw air compressors have been widely used for a long time due to its advantages such as compactness, high performance, and stability. There are many studies on these machines, but there are still many problems, especially about the screw pairs machining based on the envelope theory, to study. This paper focuses on the method for disc tool profiling and selecting the position of the disc tool to avoid undercutting phenomena, assessing the influence of the angle formed by the disc tool axis and the workpiece axis on machining errors. Research results can be used to design, locate the disc tool, and select machines to meet the required accuracy of the air compressor screw pair
