ABSTRACT:
A method and system capable of economically removing a liquid from a liquid reservoir, such as oil from an oil reservoir, by withdrawing limited quantities of the liquid in discrete steps. The system includes a dipping unit sized to be received in a passage to the reservoir, such as a casing of an oil well, and a unit for lowering and raising the dipping unit within the passage. The dipping unit is configured and oriented to have an upper end portion and a lower end portion when within the passage. The dipping unit includes a chamber, a feature for enabling a liquid to enter the chamber when at least its lower end portion is submerged in the liquid within the reservoir, and a feature for releasing the liquid from the chamber. In use, the dipping unit is lowered within passage to a liquid reservoir to enable liquid to flow into the chamber of the dipping unit when at least a lower end portion of the dipping unit is submerged in the liquid within the reservoir, and then raising the dipping unit within the passage so that the liquid is released from the chamber.
