Multistage hydraulic ,fracturing, is a highly effective method for creating multiple transverse fractures to improve gas and oil reservoir production. It is critical to minimize the fracture spacing while also ensuring transverse propagation of fractures in multi-fractured horizontal wells. In this paper, a 3D fully coupled pore pressure-stress model based on the extended finite element …

31/5/2018, · 3. ,Fracturing fluids,. The formation of fractures in reservoir rocks is initiated by ,fracturing, fluid injection under high pressure to hydraulically break the rock, hence producing the stored hydrocarbons. Fracture ,treatment, and ,fracturing, fluid design are essentially dependent on the unique properties of reservoirs.

Describing an example treatment scheme for incoming fracturing flowback water, Kimball says that the oxidant ClO 2 could be used to break oil emulsions, destroy friction reducers and kill bacteria. Hydrocarbons could then be removed by dissolved air flotation, where fine bubbles diffusion floats oil, grease and total suspended solids (TSS).

No-Damage Stimulation By Use of Residual-Free Diverting Fluids

In an RDF treatment, a hydraulic fracture will be generated first. Then, the RDF system will be injected into the formation as a diverting fluid. When fiber enters the formation, it will temporarily block the opened hydraulic fracture, increasing the net pressure and re­orienting the hydraulic fracture until a new fracture in a new direction is generated.
