One of the most popular artificial lift methods is Electric Submersible Pumps (ESP) because it can produce high flowrate even for wells with great depth. Although ESPs are designed to work under extreme conditions such as corrosion, high temperatures and high pressure, their lifespan is much shorter than expected. ESP failures lead to production loss and increase the cost of replacement, because the cost of intervention work for ESP is much higher than for other artificial lift methods, especially for offshore wells.

Therefore, this study is focused on gathering data regarding the AI on how it has transformed the entire world’s corporate sector. The essential application AI in the business world helps the business to perform better in the corporate sector. In this paper, the critical role of artificial intelligence is to grow business in different sectors and also address its ethical and unethical issues. The paper has all the initial background and comprehensive literature regarding AI and machine learning. It is discovered how the technological world has been striving to take their business on to new heights, which requires updated technological changes in internal business activities. Companies can now effortlessly interact with their customers in making their application accessible for the end-users through implementing AI and machine learning. Companies are getting higher profitability and enhancing their performance and achieving economic advantages by integrated AI. Moreover, their technological developments will take human jobs in the future, so, it is suggested that humans should work on their skills and competencies so that they can deal with unemployment. </div>展开更多

This study reviews 27 articles regarding the application of digital technology and artificial intelligence (AI) in radiological scholarship, looking at the incorporation of electronic health system records, digital radiology imaging databases, IT environments, and machine learning—the latter of which has emerged as the most popular AI approach in modern medicine. This article examines the emerging picture surrounding archiving and communication systems in the implementation phase of AI technologies. It explores the most appropriate clinical requirements for the use of AI systems in practice. Continued development in the integration of automated systems, probing the use of information systems, databases, and records, should result in further progress in radiological theory and practice.展开更多
