.... It also should be noted that Viscous slickwater allows to better control frac height growth due to lower effective pressure. Combination of these two factors in theory, should lead to a decreased resulting water cut in case of close water contact. Absence of a negative effect of the fluid...

... and injection rates of injection wells, the change in the density and composition of the produced fluids ( Burdakov D.A., Walcott D.S., 2019 ). More specifically, the changes in water cut, daily injection and production rates, gas-oil and gas-liquid ratios, fluid properties (oil density and APG composition...

... sidetracking. While keeping the production rate of the mainbore, this technology provides for an additional production from a lateral bore and allows to operate the well at the planned bottomhole pressure. upstream oil & gas analysis show producing well mainbore multi-stage fracturing water cut...

... and gas breakthroughs in the wells, which will help to decrease the water cut or GOR if a breakthrough occurs. The AICD operating principle consists in the reaction of a floating disk to the viscosity and density variations in reference to oil in the fluid passing through the device. As a result...
