A method of hydraulic fracturing includes providing a fracturing fluid to a pump. The pump includes a pressure sensor for measuring pressure at a fluid end. The method further include injecting the fracturing fluid from the pump into a wellhead via the fluid end, obtaining a first pressure measurement at a discharge side of the fluid end via the pressure sensor, obtaining a second pressure measurement at the discharge side of the fluid end via the pressure sensor, determining a pressure differential between the first pressure measurement and the second pressure measurement, and determining an operational condition of the fluid end based at least in part on the pressure differential and a known or estimated correlation between the pressure differential and the operational condition.

Systems and methods for fluid end health monitoring

A method comprising obtaining a first location of a first pointer contact on an input surface; calculating a restricted area proximate the first location; processing the first pointer contact; and inhibit processing of a second location of a second pointer contact within the restricted area.
