Activator III, a product developed by Sybron Chemicals, Inc., holds a prominent place in the history of enhanced oil recovery (EOR) techniques. While no longer actively marketed due to the company's restructuring, its legacy as a successful polymer-based flooding agent continues to influence the industry.
Understanding the Need for EOR
Traditional oil extraction methods often leave a significant portion of oil trapped in the reservoir. EOR techniques aim to increase the overall recovery rate by altering the properties of the reservoir or the oil itself. One common approach is polymer flooding, where viscous polymers are injected into the reservoir to displace the oil and enhance its flow towards the production well.
