An experimental study of proppant transport mechanisms to the pump intake in low-flow oil wells

Petroleum Research
The exploitation of low-flow oil wells following hydraulic fracturing is often hindered by residual proppant and proppant production during early production phases, which can infiltrate pumps and drastically shorten their service life.
