Abstract

Embodiments include a method for monitoring a fracturing operation that includes positioning a pump at a well site where fracturing operations are being conducted. The method also includes arranging one or more sensors at at least one of a pump inlet or a pump outlet, the one or more sensors monitoring a flow rate of a slurry. The method includes receiving flow data from the one or more sensors. The method also includes determining a pump efficiency, based at least in part on the flow data, is below a threshold. The method further includes adjusting one or more operating parameters of the pump.

First claim

The invention claimed is:

a first sensor providing a suction side flow rate for the electric-powered hydraulic fracturing pump;
a second sensor providing a discharge side flow rate for the electric-powered hydraulic fracturing pump;
a third sensor providing one or more operating parameters for the electric-powered hydraulic fracturing pump; and
a controller communicatively coupled to the electric-powered hydraulic fracturing pump, the first sensor, the second sensor, and the third sensor, the controller including at least one processing unit and at least one memory, the at least one memory including stored software instructions that, when executed by the at least one processing unit, cause the controller to:
determine an efficiency of the electric-powered hydraulic fracturing pump based, at least in part, on the suction side flow rate and the discharge side flow rate;
determine the efficiency is below a target pump efficiency;
adjust the one or more operating parameters for the electric-powered hydraulic fracturing pump;
determine an updated suction side flow rate, after adjusting the one or more operating parameters;
determine an updated discharge side flow rate, after adjusting the one or more operating parameters;
determine an updated efficiency, based at least in part, on the updated suction side flow rate and the updated discharge side flow rate;
determine the updated efficiency exceeds the target pump efficiency; and
store the operating parameters of the electric-powered hydraulic fracturing pump after adjusting the one or more operating parameters.

2. The system of claim 1 , wherein the stored software instructions, when executed by the at least one processing unit, further cause the controller to:
determine a second updated suction side flow rate, after adjusting the one or more operating parameters;
