... erosional pattern observed in the field is presented. Throughout this work, six different hydraulic fracturing completion parameters are investigated to determine the respective roles in perforation erosion. The six parameters include proppant size, proppant concentration, proppant sphericity, fracturing...

The well was flowed back between each stage to mitigate the potential for stage interference, facilitate running bridge plugs, and reduce the possibility of undesirable microseismicity. Isolation technology had been a significant concern before the treatment. However, bridge...

A single-phase CFD analysis showed how sand exiting each perforation is taken from a limited ingestion area which...
