摘要

A well test system for automatically testing a plurality of wells in an oilfield is disclosed. The system includes means for detecting leaking diverter valves. The system also includes means for purging a test separator as a function of the number of free water dumps and the number of emulsion oil dumps or for alternatively controlling the purging of the test vessel or separator as a function of time or alternatively as a function of the first to occur of a predetermined number of dumps being achieved or predetermined time having elapsed. The system also has means for determining leaking or stuck open dump valves in the water leg or emulsion oil line of the system.
