Sentence examples for sand plugs from inspiring English sources

The staged fracturing technology with sand plugs inside fractures was carried out in the mode of single-stage perforation and single-stage fracturing.

In this paper, the staged fracturing technology with sand plugs inside fractures and the staged fracturing technology with temporary plugging balls were tested in casing deformation wells.

In the present study, NGR is defined as the volumetric proportion of sandbodies (channel lags, point bars, and sand plugs and crevasses) to the total volume of the reservoir.

For the performance factor, the higher the value, the longer the screen occurs sand plugging.

Therefore, it is hard to inject the proppant into the fractures thus leading to sand plugging (Olsen et al. 2009).

Compared with the conventional fracturing, this technique can effectively increase well production, decrease the volume of fracturing proppant, and lower sand plugging risks.

The fracture spacing that satisfies the requirement of preventing sand plug as well as creating large field of fracture network is optimal.

These issues are attributed to the high fracturing pressure, limited fracture extension because of sand plugging, significant horizontal stress contrast, and discontinuities produced during hydraulic fracturing.

The lower Morrow estuarine system displays the classical tripartite division of wave-dominated estuaries (i.e. seaward-marine sand plug, fine-grained central bay, and sandy landward zone), but tidal action is also recorded.
