In this research attempts were made to estimate the in-situ stresses acting on a hydrocarbon reservoir based on routine activities of acid injection in oil reservoir. It was found that the relation between the re-opening pressure of fracture and principal in-situ stresses can be estimated using rock mechanics equations for the circular underground cavities. An appropriate relation between the m...

finding a minimum allowable radius length of a circle horizontal curve is essential to reduce earthwork cost or damage to the forest ecosystem, as well as make driving more comfortable. the present study is conducted i) to analyze different radius lengths of circle horizontal curves using an integrated approach consists of a civil3d in concert with the field surveys, and ii) to propose a set of...

One of Hungary's strategic water sectors is the supply drinking water, which relies heavily on so-called riverbank filtration systems. About 35-40% national comes from filtered aquifers. Today in Hungary, 40% population; nearly four million people's daily needs are met In future, 75% our sources will be bank-filtered, means that they also great importance for future resource management. The mai...

Digital oilfield is the main means to increase production and income. Developing ultra-short radius sidetracking horizontal wells in old requires high-performance well trajectory control. In this paper, flexible drill pipe designed by bionics principle, logging tool monitor borehole real time using gamma ray technology. The combination of can realize remaining oil recovery between dense pattern...
