Classification: CPC F  E | IPC E  F

Claim 0:
1. A system (2800) comprising:
one or more processors (2810);
memory (2820) accessible to at least one of the one or more processors;
a data interface (2830) that receives data acquired by one or more sensors operatively coupled to one or more pumps, wherein the one or more sensors comprise a pump discharge pressure transducer and a pumping rate sensor;
a control interface (2840) that transmits control signals to at least one of the one or more pumps;
a modeling component (2850), operatively coupled to at least one of the one or more processors, that predicts pressure in a well using a model, an intended pumping rate, and at least a portion of the data indicative of an actual pumping rate and a well head pressure estimate, wherein the well is fluidly coupled to at least one of the one or more pumps;
a pumping rate adjustment component (2860), operatively coupled to at least one of the one or more processors, that, in a predicted pressure mode, generates, using a predicted pressure of the modeling component and a pressure threshold, a pumping rate control signal for transmission via the control interface; and
a pressure change rate component, operatively coupled to at least one of the one or more processors, that generates a pressure change rate using a well head pressure estimate and historical pressure data and that outputs the pressure change rate to the modeling component, wherein the modeling component generates the predicted pressure using the pressure change rate.
