Abstract: An anchor for a linear actuator includes a body, a mandrel with at least two slip-receiving portions, and one or more slips. The body can be coupled to the linear actuator and the mandrel can be coupled to the power rod of the linear actuator. The linear actuator can power on and cause the power rod to move in an uphole direction toward the linear actuator. Moving the power rod can cause the mandrel to move in an uphole direction. The slip can respond to the mandrel moving in an uphole direction by expanding outward. The mandrel can continue to move in the uphole direction until the slip is received at a second slip-receiving portion.

Data based on an acoustic signal generated during a hydraulic fracturing operation in a wellbore formed through a subterranean formation can be received. An expected total flow rate of fluid being injected into the wellbore can be determined based on the data. An actual total flow rate of the fluid being injected into the wellbore can be determined. A screen-out that occurred can be identified by comparing the expected total flow rate and the actual total flow rate.
