Ultra-Low Interfacial Tension Foam System for Enhanced Oil Recovery

Ultralow interfacial tension in enhanced oil recovery (EOR)

Increasing energy demands require improved methods for enhanced oil recovery (EOR). Chemical EOR methods are most promising for maximum oil recovery, but, so far, limited due to high costs of chemicals and environmental concerns. Therefore, there is a huge interest in optimizing procedures for chemical EOR that minimize the amount of chemicals needed and rely on natural compounds, thus decreasi...

Developing a Compositional Reservoir Model for Investigating the Effect of Interfacial Tension on Oil Recovery

In this paper, a simplified formulation for compositional reservoir simulator is presented. These types of simulators are used when inter-phase mass transfer depends on phase composition as well as pressure. The procedure for solving compositional model equations is completely described. For equilibrium calculation, property estimation Peng Robinson equation of state is used. This equation ...

Microbial Enhanced Oil Recovery, Wettability Alteration and Interfacial Tension Reduction by an Efficient Bacterial Consortium, ERCPPI-2

In the present study, the potential of a bacterial consortium of Enterobacter cloacae and Pseudomonas sp. (ERCPPI-2) for microbial enhanced oil recovery was investigated. Various mechanisms of enhanced oil recovery (EOR) as a result of using ERCPPI-2 and its metabolic products were studied in detail. The obtained results showed that under simulated reservoir ...

Fractional-Flow Models for Foam Enhanced Oil Recovery

George E. P. Box wrote, "All models are false, but some models are useful." In that spirit, we examine fractionalflow models for foam enhanced oil recovery (EOR). This approach has long fascinated practitioners by transforming a physics problem first into a mathematics problem and then into a geometry puzzle. This approach, sometimes called the method of characteristics (MOC), makes many seriou...
