Distributed fiber optic sensing presents unique features that have no match in conventional sensing techniques. The ability to measure temperatures and strain at thousands of points along a single fiber is particularly interesting for the monitoring of elongated structures such as pipelines, flow lines, oil wells, and coiled tubing. Sensing systems based on Brillouin and Raman scattering are us...

Steel pile pipes used for offshore applications and port construction are subject to high levels of corrosion. To protect the top end steel pipe against aggressive corrosion conditions, splash zone is coated with epoxy. For a strength system applications, requirement long term durability coating was specified as C5 (H) Im2 according ISO 12944. The specimens glass flake reinforced epoxy were exp...

The safety of lifelines, as the most important urban facilities, under different conditions highly depends on the safe design and performance of these buried structures. This cannot be achieved unless their actual behaviors are well understood and considered at the designing stage. A new physical model was developed in Amirkabir University of Technology to study the behavior of buried pipes und...

Drilling volumes should be increased in order to increase hydrocarbon production, but this is impossible without the usage of high-quality drilling tools made modern structural materials. The study has analyze design, technological and operational methods performance various materials highlighted prospects method applications. scientific novelty consists development a new analytical model PDC d...

Abstract Daqing Oilfield as the world’s largest application area of alkali–surfactant–polymer (ASP) flooding, in recent years, with increase aging wells, eccentric wear and deformation sucker rod pipe during oil production has become more serious. In order to study effect emulsion lubrication ternary composite flooding on tubing, this paper establishes a calculation model for depth tubing under...
