Automatic chemical treatment system with liquid level sensor in chemical tank for calibration and chemical dispensing rate control

Abstract

A wellbore chemical treating system include a storage vessel for containing a treating chemical. A chemical dispenser is in fluid communication between an outlet of the vessel and a well for selectively controlling the flow of the chemical from the vessel to the well. A liquid level sensor is disposed in the storage vessel. A controller is in signal communication with the liquid level sensor and is configured to operate the chemical dispenser. The controller is configured to adjust an operating time of the chemical dispenser based on changes in a liquid level measured by the liquid level sensor over a selected period of time.
