30/12/2013, · The process has been used over a million times since the 1940s but has seen exponential growth with the introduction of new technologies such as horizontal drilling that allow access to deposits heretofore unavailable (Sakmar, 2011). Today, 90 percent of oil and gas wells in the U.S. use hydraulic ,fracturing, (Michaels, Simpson, & Wegner, 2010).

Profile control and water shutoff are indispensable both in secondary oil recovery (i.e., water injection or gas injection) and tertiary oil recovery (special fluid injection). The mechanism of profile control and water shutoff to improve oil recovery is to improve the sweep efficiency [145,146,147]. In recent years, with the reservoir conditions that implementing profile control and water shutoff are more and more …

The model is based on the following main assumptions: (i) natural fractures activate via a slippage mechanism following the Coulomb–Mohr criterion; (ii) stress perturbations due to the activation of neighbouring natural fractures are neglected; (iii) ,fluid, flow is mainly within the activated natural fractures and the growth of a tensile fracture is neglected; and (iv) the rock is saturated with a ,fluid, whose viscosity is much smaller than the viscosity of the injected ,fluid,.

In U.S. Pat. No. 5,330,005, a method of controlling proppant backflow from an underground formation is disclosed wherein the addition of fiber materials to the mixture used for hydraulic fracturing and to the well gravel-packed filter reduces proppant backflow and/or the production of fine grained grit in the packing, thus stabilizing the packing and reducing the consumption of high polymer fluids.
