The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.1 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.5 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.5 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00018 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.42 SJR: 0.217 SNIP: 0.362 CiteScore™:: 2.3 H-Index: 19

RÉSUMÉ

The problems associated with highly viscous heavy oil reservoirs, excessive heat loss to the surrounding formations, low permeability carbonate reservoirs, and the large amount of CO2 emitted during thermal processes have made solvent-based heavy oil recovery methods more attractive than thermal methods. In this study, an extensive experimental investigation was carried out to evaluate the effect of solvent type and drainage height, as the key parameters in vapor extraction, on asphaltene precipitation. Two large visual rectangular sand-packed physical models with heights of 24 and 47 cm were employed to conduct the experimental studies. Propane, methane, and a propane/CO2 mixture were considered as the respective solvents in the experiments. Also, separate experiments were carried out to measure the asphaltene precipitation at different locations in the models. The results show that for almost all of the different solvents used in this study more asphaltene precipitation was observed close to the injection points and at the oil/solvent interface. Comparing the textures of the asphaltene precipitants from different locations in the models, it was found that the precipitants close to the injection points were more brittle, while the precipitants close to the production points were more ductile. After comparing the asphaltene precipitation in the small and large models when various solvents were used, it was observed that in the case of propane injection more asphaltene precipitation was observed at different locations in the physical models.
