Asphaltene Precipitation in Algerian Oilfields: Experimental Investigation and Field Mitigation

Chemical Engineering Transactions, 2014
This study addresses two aspects for mitigating the asphaltene precipitation and deposition problem in Algerian oilfields: experimental study and field solution to the deposition problem. In the experimental study and in order to differentiate cases with

Lean HC gas injection pilots analysis and IPR back calculation to examine the impact of asphaltene deposition on flow performance

Petroleum Research, 2019
Gas injection is one of the most economical and effective approach to improve oil recovery. However, outcome of such approach is contingent to reservoir heterogeneities impacting gas override and fingering. Furthermore, injected fluid composition and its

Asphaltene Precipitation Modeling of Sadi Formation in Halfaya Iraqi Oil Field

Journal of Engineering, 2019
Asphaltene is a component class that may precipitate from petroleum as a highly viscous and sticky material that is likely to cause deposition problems in a reservoir, in production well, transportation, and in process plants.

In‐situ asphaltene capture with iron oxide nanoparticles in steam‐assisted gravity drainage (SAGD) for improved recovery and partial upgrading of bitumen

The Canadian Journal of Chemical Engineering, EarlyView.
Key improvements obtained by incorporating nanoparticles into a lab‐scale SAGD process configuration. The bar plots show enhanced oil recovery, reduced viscosity, and increased asphaltene adsorption in nanoparticle‐assisted scenarios compared with conventional SAGD.
