Abstract
A method for determining the distribution of a proppant and associated slurry exiting perforations made in a casing, which is placed in a well, includes receiving settling data describing the proppant settling in the casing; receiving a slip parameter describing a casing velocity of the proppant relative to a perforation velocity of the proppant; calculating with a computing device, based on a constant proppant concentration model, (1) initial flow rates Q'(i) of the proppant through the perforations and (2) initial flow rates Q′(i) of the proppant through the casing, wherein i is the number of perforations; and calculating with the computing device, based on (1) a variable proppant concentration model, (2) the settling data, (3) the slip parameter, (4) the initial flow rates Q′(i) of the proppant through the perforations, and (5) the initial flow rates Q′(i) of the proppant through the casing, normalized flow rates Q′(i) of the proppant through the perforations.
