    Jan 22, 2021 · In the dry system, sand production stops completely when stable retention is established, which is reflected from the single long plateau sand production line. In contrast, fluid systems present an intermittent sand production after stable retention is established, which can be seen from the fluctuated sand production lines. Overall, the intermittent sand production occurs more frequently in the crude oil …
