  • Method for treating fractured subterranean formations with controlled solids setting in wellbore
    Patent number: 11220894
    Abstract: Methods may include using geometrical and mechanical properties to generate a model of one or more intervals of a wellbore; designing a fluid pumping schedule for a wellbore treatment fluid system; simulating flow of a fluid system containing solids using the model of the one or more intervals of the wellbore, wherein simulating comprises determining the flow rate distribution within the wellbore and modeling the settling and resuspension of the solids within the flow of the fluid system; and updating the fluid pumping schedule based on the output determined from the simulated flow of the fluid system. Methods may also include determining the critical velocity of the fluid system for various concentrations of one or more of solids and additives; and selecting the concentration of the one or more of solids and additives based on the critical velocities determined.
