... lining structure are studied based on the three-dimensional finite element calculation theory, so as to determine the optimal thickness of concrete lining. The maximum tensile stress of 20cm lining during operation is about 8.73MPa, and that of 120cm lining during operation is about 4.68MPa. The maximum...

..., along with increasing the wall thickness of the production casing, will help reduce the failure length of the cement sheath. The study results have important implications for controlling wellbore integrity in shale oil wells. INTRODUCTION Multi-stage hydraulic fracturing technology for horizontal...

... Natural, bedded salt formations can be considered as host rocks for cavern storage of hydrogen produced by the conversion of excess energy to hydrogen via electrolysis. There are three active facilities in the US and one facility in the UK stores hydrogen in salt caverns (Zivar et al., 2021). Thick salt...

The study finds that when the cement sheath missing thickness ratio increases to 1/5 to 3/5 or the missing angle exceeds 30°, the casing is prone to yield failure. When the missing angle is 60°or 120°, the cement sheath is prone...
