... Abstract There has been a large number of laboratory tests run in the past, looking at recovery of heavy oil by chemical flooding (polymer, surfactant and SP or ASP systems). These tests have all shown a potential for significant incremental oil recovery from chemical injection compared...

... years. The topic has however become more popular in the recent years due to higher oil prices. Foam is generated by the introduction of surfactant along with the steam into the reservoir and reduces its mobility, thus improving the sweep efficiency and reducing heat losses. There has been no review...

... products were selected that are non-toxic, non-flammable and non-carcinogenic. The elaborated set up and test procedure enables identification of the most effective product and to optimize its concentration. In the first phase of this evaluation Dispersants based on biodegradable Surfactants are tested...

...-low interfacial tensions and high solubility. Deep understanding of microemulsions and surfactant technology can be used to systematically develop a custom solution depending on the well requirements and crude oil characteristics. Viscosity measurements and microscopy techniques were used...

... Abstract Alkali-surfactant-polymer (ASP) flooding is a commercially viable enhanced oil recovery method. The complexity of chemical interactions, multi-phase flow, emulsification, capillary number changes and upscaling issues, especially in highly heterogeneous reservoir, make field designs...
