Classification: CPC F  E | IPC E  F

Claim 18:
19. A method (2882) comprising:
receiving 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 (2883);
predicting pressure in a well using a model, an intended pumping rate, and at least a portion of data indicative of an actual pumping rate and a well head pressure estimate, wherein the well is fluidly coupled to the one or more pumps (2884);
generating, in a predicted pressure mode, a pumping rate control signal using the predicted pressure and a pressure threshold (2885) and utilizing a pressure friction model that predicts a friction pressure that is a function of pumping rate and a fluid friction property; and
transmitting the pumping rate control signal via a control interface to control operation of the at least one of the one or more pumps (2886).
