Squeezing the inhibitor into the reservoir can prevent deposition of asphaltenes in the near-wellbore area. It is important that the inhibitors are added to the crude oil before the asphaltenes become destabilized and flocculation occurs. Asphaltene dispersants do not prevent precipitation, but maintain...

The present invention provides a method of asphaltene control in a hydrocarbon fluid, the method employing a composition comprising: a dispersant of formulae (I) or (II), including salts thereof, wherein T or T' is hydrogen or a polymerizing terminating group; A is C16-20 alkylene or alken...
Monte Carlo computer modeling has been applied to interpret some unexpected trends of molar mass of the Puerto Ceiba asphaltene clusters at different concentrations of inhibitor, assuming that inhibitors efficiency is directly related to their adsorption on the surface of asphaltene or its complexes. It...
Furthermore, asphaltene adsorption onto the reservoir rocks was studied in the presence of a recently developed asphaltene inhibitor. The inhibitor significantly reduced asphaltene adsorption at any initial concatenation of asphaltene. Moreover, changes in the rock permeability due to asphaltene precipitation...

stronger these interactions for a particular inhibitor, the better performance its likely to have[118]. The effect of inhibition is not permanent, and there would be a point where the inhibitor would become ineffective due to continued stress such as long residence time in a system. In that ...
