A unidirectional one-dimensional approach for asphaltene deposition in large length-to-diameter ratios scenarios [PDF]

Journal of Petroleum Science and Engineering, 2018
Abstract Asphaltene deposition in wellbores has been recognized as the cholesterol of petroleum for decades causing billions of dollars in losses to the oil and gas industry every year. This necessitates great efforts in precise and fast forecasting of the production problems induced by asphaltene deposition.
