... is a precursor to virtually zero CO2 emissions in the future. Liquefied hydrogen storage tanks are considered a non-toxic and reliable way to achieve this goal. However, many aspects still need to be clarified for the fracture resistance of the inner tank, which is the key to the safe storage of liquefied...

... ABSTRACT Control of ductile fracture propagation to ensure arrest is critical to design of pipelines transporting dense-phase CO 2 . Two factors that control crack arrest are fracture resistance and decompression pressure from the escaping fluid. Current engineering methodologies treat...

... ABSTRACT The fractures in Permian stratum of Shunbei oil and gas field are well developed, the formation fracture pressure is low, and the leakage problem is very severe during the cementing jobs. It is difficult to solve this problem by using traditional low-density cement slurry and staged...

... ABSTRACT Predicting crack initiation and its growth in marine concrete is still a major challenge. In present work, the fidelity of the peridynamics (PD) theory in predicting marine concrete fracture is investigated through a comparative study. PD predictions for fracture propagation paths...

... Abstract Fracture ballooning frequently occurs in deep water drilling and is often confused with a well kick, which may lead to costly well control procedures. Although it has been studied for almost 30 years, less effort has been made with respect to deep water wells. Specifically...
