... = flowback analysis), was recently introduced to accelerate information obtained from a DFIT. After the pump-in stage, a brief shut-in (~ 5 minutes) is followed by flowback of the well at a (rule-of-thumb) initial flowback rate of 2-5% of the injection rate for (typically) 2-4 hours. Recent studies have...

... of stress-relief from rock-acid reaction, early in the treatment. The enhanced fluid leak-off resulting from acid reaction requires employing appropriate gel type and volumes in the pad stages; also, the injection rates must be designed to promote uniform fluid distribution across the multiple sleeves...

... accurately. However, instead of opting for a complex deep learning algorithm like Shen et al. (2020) , we opted to implement a simpler rule-based model to improve operational efficiency of the tool. Therefore, at each new timestamp we look to see whether our injection rate and pressure are high enough...

..., a laboratory-based 30-foot horizontal clear apparatus with three perforation clusters is used. Fresh water (~1 cp) is utilized as the carrier fluid to transport the proppant. This research incorporates the effect of testing three different injection rates each at four different proppant concentrations...

... Abstract Water hammer is oscillatory pressure behavior in a wellbore resulting from the inertial effect of flowing fluid being subjected to an abrupt change in velocity. It is commonly observed at the end of large-scale hydraulic fracturing treatments after fluid injection rate is rapidly...

This experimental work shows that viscosity has a greater impact on the proppant transport than fluid density does, thus implying a larger impact on the resulting fracture conductivity...
