| Περίληψη | Laboratory and field data from the Snorre reservoir oil in the North Sea confirm that asphaltenes, due to the fact that they precipitate when the oil in which they are contained is subjected to considerable compositional changes, can be used as a natural tracer for monitoring the success of a gas miscible flooding during IOR projects. The field data reveal that the change of GOR in producing wells affects the asphaltenes content of the producing oil only in the cases where injection gas has gone into solution. A series of single and multiple -both forward and backward- contacts were performed in the laboratory to simulate the compositional changes that the Snorre reservoir oil undergoes during a gas injection project. The asphaltenes solubility during the single contacts was reduced by increasing the amount of dissolved gas in the oil. During the forward contacts, asphaltenes precipitation increased as the number of contacts increased, while during the backward contacts, the opposite trend was observed. Furthermore, compositional characterisation of the precipitated asphaltenes produced under different experimental conditions provides a better understanding of the precipitation process. | en |
