Abstract
A method of recovering oil from a reservoir that contains it, crossed by an injection well at least and a production well at least, whose method includes the steps of: A) to produce said deposit through the well or production wells by means of propulsion with gas in solution and reduction of the pressure to a point below the pressure of the bubble point but within the critical gas saturation of said deposit to the existing pressure in it; B) finish said propulsion with gas in solution and inject water into said reservoir through the well or injection wells mentioned while maintaining the existing pressure in said reservoir and simultaneously causing said reservoir to be produced through the well or production sites mentioned above. A point at which the speed of oil production has reached a predetermined point of completion; C) finishing said injection of water and causing said reservoir to be produced through the well or production wells mentioned by propulsion with gas in solution and decrease of the pressure to a point below the pressure of the bubble point but within the critical saturation of gas from said deposit to the pressure then existing therein; D) finishing said propulsion with gas in solution and injecting water into said reservoir through the well or injection wells mentioned and simultaneously causing said reservoir to be produced by the well or production wells mentioned up to a point where the production rate of oil has reached a predetermined completion point and E) then repeat steps (a) and (b) to the point where the reservoir abandonment pressure is reached.
