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.

While there is a consensus in the literature that embracing nanodevices and nanomaterials helps in improving the efficiency and performance, the reason for the better performance is mostly subscribed to the nanosized material/structure of the system without sufficiently acknowledging the role of ,fluid, flow mechanisms in these systems. This is evident from the literature review of ,fluid, flow ...
