Tight oil reservoirs are commonly developed by a combination of horizontal wells and multistage hydraulic ,fracturing, techniques. The characterization of complex fracture networks after ,fracturing, treatments is the common challenge for unconventional reservoirs. Tracer ,flowback, profiles can reveal a fracture network at an individual stage.

Fracturing Fluid Flowback REI has recently developed a computational model to predict, flowback, of hydraulic fracturing fluids after stimulation has been completed. Using a combination of force and stress balances and computational fluid dynamics, our model is able to simulate many of the complex physical interactions that play a role in determining flow back rate and overall fluid recovery.
