Abstract: An auxiliary operation device for a droplet dispenser includes a droplet sensor, an imaging device and a processor. The droplet sensor has a detected area located between a droplet dispenser and a target area, wherein the droplet sensor detects a droplet output from the droplet dispenser, and outputs a corresponding droplet detection signal. The imaging device captures an image of the target area. The processor obtains a dripping time point at which the droplet passes through the detected area according to the droplet detection signal, and determines whether the target area is shielded within a first time range according to the image, so as to evaluate whether the droplet has successfully dropped into the target area. The above-mentioned auxiliary operating device of the droplet dispenser can objectively determine whether the droplets successfully drops into the target area, and improve the accuracy of judgment.

Abstract: A method of analyzing flowback of a downhole system includes generating active flowback data by monitoring an active flowback from a wellbore. Historic flowback data for historic flowback from the wellbore is used to determine a flowback cluster. The flowback cluster is selected based on comparing the active flowback data to the historic flowback data and determining one or more data instances of the historic flowback data that have features that are similar to that of the active flowback data. Based on the flowback cluster, one or more thresholds may be determined in order to generate an alert when the active flowback data exceeds the thresholds.
