Permeability measurements indicate whether the fracturing fluid damages the formation during hydraulic fracturing that in turn reduces oil productivity during flowback. While coreflooding is useful for comparing the performance of different flowback aids, it is unable to resolve the mechanisms associated with porescale transport.

Flowback Procedure: Manifolded Frac tanks are set in a line and positioned near the EC unit. When the Flowback begins the returned Frac Fluids are used to fill up all of our source tanks. A pump is set near the Ec unit pumping the returned Frac Fluids through the EC for treatment and into a 500 bbl Weir tank.

Injection of fracturing fluid with much more proppant is the next stage. Sand or ceramic granules are mixed with water and chemical additives in special units that are called blenders. Subsequently, pumps sets inject the mixture through the manifold (a device that interconnects all pumps sets and delivers all fluids injected to and recovered from the well) and the wellhead into the borehole.
