1/2/2019, · Indeed, surfactant is usually used as an additive to reduce the capillary trap of the ,fluid, in rock matrix to promote the ,flowback of fracturing, fluids (Jiang et al., 2013). The reason is that DR of surfactants results from rod-like micelles produced by association, which is not stable by itself.

The hydraulic ,fracturing, process involves the injection of fluids, gas, proppant and other additives under high pressure into a geological formation to create a conductive fracture. The fracture extends from the well into the coal reservoir, creating a large surface area through which gas and water are produced and then transported to the well via the conductive propped fracture channel

Oil recovery from reservoirs, indeed, depends on different ,factors, such as the Mobility Ratio (M) and Capillary Number (N c).The first represents the oil capacity to move through the pores. If M >1, more ,fluid, needs to be injected to obtain an optimal oil saturation into the pore. While M <1, means that mobility ratio is favourable.
