ABSTRACT:
A secondary oil recovery method and system utilizing a concentric tank arrangement receiving crude oil from an oil well in the inner tank thereof with the crude oil being heated by a solar furnace to facilitate separation of water, oil and gas with the water being disposed within the outer tank for insulation of the inner tank and for use in an injection well for water flooding with the gas being removed from the inner tank from a dome trap at the top thereof and separated oil being moved to a storage tank or other point of use from the inner tank. The solar furnace includes heat exchange tubes disposed in the inner and outer tanks and oriented in relation to a heat collector panel and provided with a heat exchange medium therein by which solar energy is used to heat the crude oil in the inner tank as well as the water at the bottom thereof and water in the outer tank.
