The amount of ,flowback, varies, and it can be as little as 10% or essentially most of the water. Typically, 20 - 40% of the water returns to the surface. Initially, this water will primarily contain contaminants found in the ,fracturing fluid,. Secondary contaminants include contaminants naturally occurring in the ground.

While evaluation of early gas-production data to assess likely rate decline and ultimate gas recovery has been reported in literature, flowback-water recovery has been given little consideration. Fracture-fluid flowback is defined herein as aqueous phase produced within 3 weeks following a fracture treatment (exclusive of well shut-in time).

19/11/2014, · In laboratory, clear fracturing flowback fluids was obtained by simulating the actual gelling and gel breaking process during fracturing construction in the field. The gelling fluid was prepared with 4 wt% VES and 96 wt% formation water. The gel breaking process was realized by adding 2 wt% kerosene into the gelling system.
