Claim 9:
10. A system for determining an integrity of a diversion in a multi-stage fracturing operation, the system comprising:
one or more processors; and
at least one computer-readable storage medium having stored therein instructions which, when executed by the one or more processors, cause the one or more processors to:
monitor flowing of a fracturing fluid into a wellbore during a fracturing operation of a first stage of the wellbore, wherein the fracturing fluid forms a fracture at a location of the first stage;
sense fracturing fluid pressure via a sensor during the fracturing operation and communicating sensed pressure data to a controller implemented through the one or more processors;
sense a flow rate of the fracturing fluid via a sensor during the fracturing operation and communicating the sensed flow rate data to the controller;
plot, through the controller, data points of the sensed pressure data vs. the sensed flow rate data to a visualization device which is configured to visually present the plotted data points to an operator as a plot;
initiate carrying of diverter particulates in the fracturing fluid and depositing the diverter particulates in the fracture, thereby diverting the fracturing fluid away from the fracture;
plot the data points as the diverter particulates are being deposited in the fracture and determine an integrity of a diversion formed by the deposited diverter particulates based on a progression of the plotted data points displayed on the plot;
identify a cluster of data points plotted at a constant flow rate, and wherein identifying the cluster of data points initiates additional carrying of diverter particulates in the fracturing fluid and depositing the diverter particulates in the fracture, thereby diverting the fracturing fluid away from the fracture; and
determine whether data points continue to populate along a constant flow rate in response to the additional carrying of diverter particulates in the fracturing fluid or whether the data points indicate a change in flow rate in response to the additional carrying of diverter particulates in the fracturing fluid.
