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.

Hydraulic ,fracturing, is essential for producing gas and oil at an economic ,rate, from low permeability sands. Most ,fracturing, treatments use water and polymers with a gelling agent as a ,fracturing fluid,. The water is held in the small pore spaces by capillary pressure and is not recovered when drawdown pressures are low.

The formation of scale deposits upon tubing, casing, perforations, and even on the formation face itself, can severely constrict ,fluid, flow and reduce the production ,rate, of oil and gas wells. In addition to lost production, a considerable portion of the workover budget is expended in efforts to remove these deposits and prevent their recurrence.

15/2/2021, · It should be noted that various divalent cations (e.g., Ca 2+, Mg 2+, Ba 2+, Sr 2+) can form stable scale deposits (e.g., CaCO 3, MgCO 3, CaSO 4) in the wellbore when reusing PW for hydraulic ,fracturing, operations, thereby limiting the efficiency of friction reducers, accelerating corrosion ,rate, in the reservoir, and even blocking pipelines and wells (Chang et al., 2019b), which pose a ...

Since the nanoscale pores dominated in the shale, the induced high capillary force was considered to be the primary factor for the ,fracturing fluid, spontaneously imbibing into the formation (Yang et al., 2017). For the second one, a great debate also appeared about whether the low ,flowback rate, is good or bad for the shale gas production.
