Fracturing-Fluid Flowback Simulation with Consideration of ...

Fracturing-fluid flowback is a complex process, involving fluid transport, proppant transport, fracture closure, as well as their interactions. Proppant transport has long been recognized in modelling fracture propagation during the fracturing-fluid pumping process.

Fracturing-Fluid Flowback Simulation with Consideration of ...
Fracturing-Fluid Flowback Simulation with Consideration of ...

Involving the fluid-particle hydrodynamic process and hydraulically created fracture network, fracturing-fluid flowback in hydraulically, fractured shale wells, is a complex transport behavior. However, there is limited research on investigating the influence of proppant transport on the fracturing-fluid flowback behavior and flowback data analysis.

Fracturing Fluid Flowback — Reaction Engineering International
Fracturing Fluid Flowback — Reaction Engineering International

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.

FLOWBACK AID FOR FRACTURING FLUIDS - Schlumberger ...
FLOWBACK AID FOR FRACTURING FLUIDS - Schlumberger ...

A flowback aid may be included in the, fracturing fluid to reduce capillary pressure and water blocks,,, thereby improving the kinetics of the flowback and preventing or minimizing the leaving-behind of, any, substantial amount, of the fracturing fluid. Flowback aids, such as surfactants, have also been shown to aid in the “clean-up” of the proppant pack, thereby accelerating the flow of hydrocarbons through the …

16/4/2020, · Fracturing fluids and additives. PetroWiki. Jump to navigation Jump to search. Fracturing fluids are, pumped into the well to create conductive fractures and bypass near-wellbore damage in hydrocarbon-bearing zones., The net result is an expansion in the productive surface-area of the reservoir, compared to the unfractured formation.

Zero Flowback Rate of Hydraulic Fracturing Fluid in Shale ...
Zero Flowback Rate of Hydraulic Fracturing Fluid in Shale ...

A, high flowback rate, of hydraulic fracturing fluid (HFF), yields a high gas production rate in a tight sand gas reservoir., This idea is well followed when it comes to the hydraulic fracturing of a shale gas well.
