... performance. Pumping data such as treating pressures, injection rates, and proppant concentrations were used to determine, in real-time, the number and type of fractures created during the hydraulic fracture treatment. This allowed for operational adjustments to be made to optimize pumping rate and proppant...

.... Meanwhile, the addition of 1.0 wt% AOS reduced the apparent viscosity of the hydraulic fluid to 0.56 cP. Higher viscosity is crucial to ease the flow of the hydraulic fracturing fluid to create the fractures and bring the proppant into the fractures created. The flow loop test showed that the hydraulic...

... and retention time within the rock formation. It is well known that proppant is considered as one of the main additives in simulating unconventional wells, and its primary function is to maintain a conductive fracture during well production. Beyond that, it can serve as a matrix to deliver chemicals deep...
