A single-crystalline WO<sub>3</sub>–rGO composite has been successfully prepared and applied into gas detection. Impressively, this permit-3D porous nanostructures display enhanced NO<sub>2</sub> sensing properties.
Results are presented from two-phase flow wax deposition tests using a state-of-the-art, high-pressure, multiphase test facility. Wax was found to be pattern specific and dependent on the velocities of fluids. occurs only along pipe wall in contact with waxy crude oil. An increase mixture velocity results harder deposits, but lower deposit thickness. The buildup trend at low is similar that observed laminar single-phase tests. high turbulent Thinner deposits bottom than top were horizontal...
A Joint Industry Project to investigate paraffin deposition in multiphase flowlines and wellbores was initiated at The University of Tulsa May 1995. As part this JIP, a computer program, based on the molecular diffusion theory, developed for prediction wax during flow pipelines wellbores. program is modular structure assumes steady-state, one-dimensional flow, energy conservation principle. This paper will describe simulator predicting that includes coupling fluid solid-liquid-vapor...
Abstract As a high-efficiency tool to convert rotating kinetic energy hydraulic pressure head, the electrical submersible pump (ESP) is widely used in petroleum industry increase hydrocarbon fluid production rates. Previous studies showed that presence of gas would cause ESP head degradation. Flow behaviors ESPs under gassy conditions, such as pockets, further deteriorate performance. It important investigate flow structure inside with involvement. In this paper, we use Computational Fluid...
Tungsten trioxide nanostructures have received considerable attention due to their enhanced gas sensing properties and promising applications in the field. Herein, tungsten oxide (WO3) with a lamellar structure was prepared by facile but feasible hydrothermal process applied for detection. The structures, morphologies surface characteristics of as-obtained products were characterized X-ray diffraction, photoelectron spectroscopy, scanning electron microscopy, transmission microscopy...
Mesoporous single crystal In<sub>2</sub>O<sub>3</sub> with high specific surface area and oxygen vacancy concentration are prepared for enhanced ethanol gas sensing performance.

Abstract Solids blockage due to wax deposition and/or hydrate formation in subsea flowlines is one of the major risks for deepwater production systems. Blockage causes high pressure drop and even stop oil gas production. The ability determine location, length severity blockages allows operators select cost-effective mitigation or remediation strategies execute corresponding procedures efficiently Due difficulty access flowlines, a remote technique detect highly desirable. This study...
Oil and gas producing rates have increased rapidly with the development of shale oil fracturing technology. Besides, advances in horizontal wells slugging issue, especially complex geometry wells. Therefore, Artificial lift systems, rod-pumps electrical submersible pumps, always suffer from associated require an economical way to avoid problems like lock, pound, interference slugging. Among all kinds downhole separator, gravitational separator are most devices, which can handle severe...
Coal and gas outburst has been one of the main threats to coal mine safety. Accurate prediction is key avoid accidents. The data actual complete by default in existing model. However, fact, missing abnormal value often occur, which results poor performance. Therefore, this paper proposes use correlation coefficient filling real time for first time. identification completed based on Pauta criterion. Random forest model used realize performance sensitivity 100%, accuracy 97.5%, specificity...
