Abstract
A method for determining an end-of-stage (EoS) state indication of a fracking operation occurring at a fracking site comprises: receiving an end-of-stage (EoS) detection model; receiving wellsite activity data; determining a positive activity data health indication in relation to the wellsite activity data using the EoS detection model; determining an idle activity indication from the wellsite activity data using the EoS detection model; receiving wellsite stage data; determining a positive stage data health indication in relation to the wellsite stage data based on the EoS detection model; and determining a positive EoS state indication from the wellsite stage data using the EoS detection model.
