... previous research, it is understood that fines migration won't start until the flow velocity is greater than the critical velocity. Through many long-term core flood tests (extended fines migration test), we conclude that the permeability damage induced by fines migration is a function of the pore volume...

... According to Najmi et al. (2016) the critical velocity is defined as minimum velocity needed to keep particles moving along the pipe, which has the same definition as this study. The following Table 2 shows the experimentally measured critical velocity for particle size of 150 µm with five...

... Abstract Sand is often produced with oil and gas even though sand control practices are used. To successfully transport solids in pipelines, the fluid velocity must exceed the critical velocity. Solids transport models are used to predict this velocity. However, for the same input field...

... Loading. It is basically the inability of gas to remove liquids being produced in the wellbore. This occurs when the velocity of gas being produced falls down a particular value known as "critical velocity". The produced liquid will accumulate in the well creating a static column of liquid, therefore...
