Abstract
Methods for estimating the solvency potential for various chemical additives used for asphaltene deposit remediation or inhibition have been developed. These methods can be used for remediating or inhibiting asphaltene deposition in various applications including upstream production (e.g., near-wellbore, downhole, flow-lines, separators), midstream processes (e.g., pipe lines, transport, and storage), and downstream (e.g., hydrocarbon refining).
