... conditions. The Dynamic Asphaltene Inhibitor Test used a simple dynamic flow equipment consisting of capillary coil and filter to detect asphaltene precipitation and deposition independently. Based on Asphaltene Inhibitors experimentally screened through a series of Dynamic Asphaltene Inhibitor Test, four...

..., the injection pressure of carbon dioxide would be kept above the minimum miscibility pressure. Thus carbon dioxide is miscible with the oil present in the reservoir. This paper primarily focuses on understanding the effect of crude oil composition on the change in wettability and asphaltene precipitation...

... Abstract Carbon dioxide miscible flooding is known as a very efficient and challenging enhanced oil recovery (EOR) method. Besides the high oil recovery efficiency, the asphaltene precipitation and deposition is believed to be triggered by a perturbation of the thermodynamic equilibrium present...

... Abstract This work was motivated for establishing a robust asphaltene flow assurance engineering using asphaltene inhibitor to mitigate the risk of asphaltene precipitation in tubing. For this purpose, the best candidate was selected through asphaltene dispersant test (ADT). Furthermore, its...

... at the onset of asphaltene precipitation for the samples (∆RI) are less than 0.045 while the CII for the four crude oil samples A, B, C, and D are 1.09, 1.43, 5.64 and 5.83 respectively. These indicate that all the oils investigated have high tendency to precipitate asphaltene. wax remediation wax...

... type of nanofluid, additional tests were performed including the effects on asphaltene precipitation using a flow assurance system. The experimental results show that, the Aluminum oxide nanofluid at a concentration of 0.05 wt.% reduced the emulsion viscosity by 25%. The mixed nanofluid of Silicon...

... remediation asphaltene precipitation reservoir fluid sampling revisited Introduction Shutting in the reservoir to build-up pressure again will re-dissolve gas into the oil 7 . Obtaining a stable GOR is more difficult for saturated oil reservoirs. However, by flowing at a lower rate a stabilized...

... bottom-hole fluid samples have built the onset pressure curve of asphaltene precipitation, which indicated the asphaltene deposition in the near wellbore region under the production conditions. 1 Then the intensive laboratory tests have been carried out to evaluate some commercial additives in terms...

... Abstract Asphaltenes precipitation is one of the major operational problems affecting oil production in the Bangestan reservoir in south of Iranian fields. Precipitation of asphaltenes in reservoirs, wells and production facilities can have severe detrimental impact on the economics of oil...
