WebbIn this case, some mitigation actions can be taken, for example HCO (or even slurry oil) recycle. In many refineries, the HCO product has a low value. Hence HCO recycle is common practice to produce coke and help the heat balance in FCC units processing light feeds. ... As regenerator temperatures cool, catalyst circulation rate (CCR) ... WebbThe FORM-A-SQUEEZE slurry lost-circulation (LC) plug can be used to stop losses occurring in any water-based and nonaqueous-base fluid and can be easily mixed in freshwater, seawater, or oil- or synthetic-based fluids. It was designed to be used as an openhole remedial and preventive lost-circulation squeeze
WebbWhere conventional circulation cementing places the cement slurry below drilling fluid and spacer fluids in the annulus, and thereby normally leads to density-stable configurations, reverse cir-culation places the cement slurry above the normally lighter … Webb22 okt. 2024 · At the same time, this thixotropic cement slurry is easily reversed to a fluid state by resuming circulation or by applying some shearing force to it.
