Abstract: A method of predicting hydraulic fracturing and associated risks of hydraulic fracturing operation is proposed. The methods use the mathematical simulation which allow to predict the geometry of a hydraulic fracture and location of fluids, propping agents (proppant), fibers and other materials therein. Reconsidering the fracturing design allows to remedy the possible risks (overflush, screen-out, bridging, gel contamination, temperature effects).

Abstract: A method of stimulating a subterranean formation includes acquiring stimulation treatment input data, simulating a transport of at least one material transport present in a stimulation treatment design with a transport simulator model, determining and preparing the treatment design and performing the stimulating treatment according to the selected treatment design. As recited, simulating includes assuming that for each time stage of the stimulation treatment a velocity field for the at least one material transport and a stimulated flow domain geometry are known and calculating at each time stage the distribution of at least one physical quantity of the at least one material transport using a Lagrangian approach.

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.
