The dimensionless imbibition capacity depicts the capacity of shale reservoirs to imbibe ,fracturing fluid,, which has a negative linear correlation with ,flowback, efficiency. In addition, dimensionless time and fracture width are related to the ,fracturing, operations, and are enhanced by increasing the shut-in periods and proppant concentration.

After the simulation work, we conclude that when the formation pressure is higher, the total, flowback, rate increases; for reservoir wettability, the less water wet the reservoir is, the more the total, flowback, rate has. The, influence of fracture, development is diversified; a, fracture, location will determine whether it becomes promotion or, resistance, to the, fracture fluid flowback, process.

Microbial communities in flowback water impoundments from ...

The reuse of ,flowback, for subsequent hydraulic ,fracturing, is now common practice in the Marcellus region (Gregory et al., 2011). It is likely that the microbial community in the recycled ,flowback, served as a seed for these impoundments. Furthermore, the recycling of ,flowback, may lead to the selection of organisms that are resistant to certain biocide treatments (Russel et al., 1997; Chapman, 1998; …

Approximately 10–30% of the ,fracturing fluid, will return to the surface as ,flowback, water (EPA, 2012). In addition, naturally occurring salts, radioisotopes, and other elements will appear in ,flowback, water if there is mixing between the ,fracturing fluid, and the brine present in the formation (Alley et …

However,, fracturing fluid can interact with formation minerals and the connate water therein, resulting in high contents of suspended and dissolved solids in the flowback fluid, [ 20, 21 ]. When this flowback fluid is reused, the proppant-carrying capacity of the gel can be seriously weakened.

1/3/2021, · Wang (2015) suggested that, increasing the contact area between, the, fluid and, the, reservoir promotes, the, fracturing fluid into the, matrix. However, if the capillary force in water-wet reservoirs drives matrix imbibition during fracturing, and then it would serve as the resistance during the flowback.
