Encapsulation of particles using brittle coatings for subterranean applications
… which reduce or "break" the viscosity of fracturing fluids, was explored.;The viscosity-reducer was ammonium persulfate. Polyurethane and acrylate coatings were investigated. The coated particles were assessed for dissolution in water before and after being subjected to a compression test. …

Numerical simulation of fluid flow, proppant transport and fracture propagation in hydraulic fractures for unconventional reservoirs.
… The proppant transport and suspension in thin fracturing fluid used in unconventional reservoirs are considerably different from those of fracturing fluids in conventional reservoirs, due to the very low viscosity of fracturing fluids used in the unconventional reservoirs, poor ability to …

Fracture Stimulation by Nano-assisted Foam-based Fluids in High-Temperature Reservoirs
Fracture stimulation, or hydraulic fracturing, has been increasingly implemented to extract and enhance oil and gas production from unconventional resources with very low permeability. In this stimulation technique, fracturing fluid is injected at very high pressure into the underground to initiate …

Characterization of Filter Cake Buildup and Cleanup under Dynamic Fluid Loss Conditions
Hydraulic fracturing is a popular stimulation method in tight gas and shale gas reservoirs that uses a viscous fluid to fracture the reservoir rock and uniformly transport proppant to create a highly conductive path that is kept open by the proppant after fracturing. This method is used to improve …

Investigation of post hydraulic fracturing well cleanup physics in the Cana Woodford shale
Hydraulic fracturing was first carried out in the 1940s and has gained popularity in current development of unconventional resources. Flowing back the fracturing fluids is critical to a frac job, and determining well cleanup characteristics using the flowback data can help improve frac design. It …

Regulating the disclosure of chemical additives in the hydraulic fracturing process: a comparative analysis between Canadian and South African Law
Broadly defined, hydraulic fracturing is a stimulation technique used in the oil and gas industry to create additional permeability through creating fractures in an unconventional gas reservoir. Desktop estimates predict that shale deposits beneath the semi-desert Karoo region in South Africa could …
