Claim 0:
1. A method for determining an integrity of a diversion in a multi-stage fracturing operation, the method comprising:
flowing a fracturing fluid into a wellbore during a fracturing operation of a first stage of the wellbore, thereby forming a fracture at a location of the first stage;
sensing fracturing fluid pressure via a sensor during the fracturing operation and communicating sensed pressure data to a controller;
sensing a flow rate of the fracturing fluid via a sensor during the fracturing operation and communicating the sensed flow rate data to the controller;
the controller plotting 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;
carrying diverter particulates in the fracturing fluid and depositing the diverter particulates in the fracture, thereby diverting the fracturing fluid away from the fracture;
plotting the data points as the diverter particulates are being deposited in the fracture and determining an integrity of a diversion formed by the deposited diverter particulates based on a progression of the plotted data points displayed on the plot;
identifying a cluster of data points plotted at a constant flow rate, and wherein additional carrying of diverter particulates in the fracturing fluid is initiated in response to identifying the cluster of data points; and
determining 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.
