A method of enhancing oil recovery from an oil bearing formation through secondary fluid displacement. The method includes the step of injecting a second displacement fluid of a second density as a secondary fluid displacement into an oil bearing formation which has been subjected to a primary fluid displacement by a first displacement fluid of a first density from one of above or below a production zone. The first displacement fluid and the second displacement fluid are immiscible in oil. One of the first displacement fluid and the second displacement fluid has a density that is greater than oil and the other of the first displacement fluid and the second displacement fluid has a density that is less than oil. The secondary fluid displacement is in the same direction as the primary fluid displacement to displace oil remaining in the formation that was not displaced by the primary fluid displacement. The injection of the second displacement fluid is controlled to prevent displacement of substantial quantities of the first displacement fluid from the formation and avoid having to alter the position of the production zone as injection of the second displacement fluid continues.
