ABSTRACT:
A method for removing floating immiscible liquids from a well containing both the floating immiscible liquids and water, where the floating immiscible liquids and water meet at a water interface, by controlling a cone of depression within the well. A removal system for removing said floating immiscible liquids is used including a microprocessor, a discharge water line and an upper water interface sensor where at least a portion of the discharge water line is located within the well. The upper water interface sensor is located within the well at a sensor location. The method includes the steps of inserting a modulating control valve into the discharge water line, the modulating control valve being connected to be controlled by the microprocessor, opening the modulating control valve when the water interface rises up to the sensor location, closing the modulating control valve when the water interface falls below the sensor location, and operating the microprocessor to open and close the modulating control valve at a rate which keeps the water interface at a substantially static level.
