... analysis of an ESP GH, specifically the consequences of mechanical breakdown of impeller blades. Solids, such as scale, sand and debris upstream of the ESP, can cause mechanical failures or wear of exposed parts. Impellers or augers used in rotating gas separators and gas handlers are at higher risk...

...Friction Losses Flows in the impeller and diffuser are treated as channel flows. In the analysis, we assume fluid fills all space in the impeller channels and diffuser channels. Zhu et al. (2021) proposed the following set of equations to estimate the friction losses across the ESP stages...

... of testing different impeller combinations up to 90% intake GVF. The findings present a potential economical option for managing high GVF flows in ESP operation, beneficial to boosting and maximizing production from a field asset. The pump used was a two-stage, radial-type centrifugal pump with 3.78-inch...

... wear reservoir society of petroleum engineers bearing impeller flow stage Introduction Electrical Submersible Pumps (ESPs) were determined to be the most efficient Artificial Lift technology for an onshore field in the Middle East as they are able to produce at very low bottom-hole...

... behaviour under a range of operating conditions. We also present examples of highly resolved, quantitative velocity fields acquired within impeller and diffuser passages. This information provides improved understanding of the fluid mechanics and can be used directly for design purposes or for validation...
