Fracturing fluid trapped in the micro-nano induced cracks is difficult to flowback due to the strong capillary force, but under the capillary force, the liquid can move from induced cracks to small pores, which can greatly increase the main gas flow channel, and thus after well shut-in for a time, shale gas can flow out of the formation.

Flowback fluid, goes through the open topped ,flowback, tanks before being stored for reuse. If gas is expected or detected in the ,flowback,, it is diverted to the sand filter and separator. Any separated gas is then sent to the flare. ,Flowback fluid, is sent to the frac tanks for reuse in the ,fracturing, process.

15/1/2018, · Hydraulic ,fracturing, is the process of pumping ,fluid, into a wellbore at an injection rate too high for the formation to accept without breaking. During injection, the formation’s resistance to flow increases, and the pressure in the wellbore increases to a value called the break-down pressure, which is the sum of the in-situ compressive stress and the strength of the formation.
