Abstract: Hydraulic fracturing is considered as an effective approach for the development of tight oil reservoirs. Unlike conventional reservoirs, after a large volume injection of the fracturing fluid, the flowback rate in tight oil reservoirs is considerably lower whereas the underlying mechanism explaining water retention remains unclear.

The check-valve assembly, which includes a ceramic ,nozzle,, a ceramic or aluminum ball, and an aluminum plate, is used instead of the standard ResFlow ICD ,nozzle, assembly within the ICD housing. The check-valve assembly prevents ,fluid, loss through the nozzles during washdown and then controls the flow of hydrocarbons during production in the same way as a conventional ResFlow ICD.

Multistage hydraulic fracturing is a key technique for the effective exploitation of tight reservoirs. In the process of multistage hydraulic fracturing, a large amount of fracturing fluid is injected into the formation. However, field data show that the flowback rate of the fracturing fluid after fracturing is generally no higher than 30% [1].

The nozzles induce back-pressure on the flow inlet. The smaller the throat diameter is, the greater the back-pressure is. Therefore, proper sizing of the nozzle is important. Flow through the nozzles was characterized using CFD simulations and a sizing methodology has been proposed.
