Development of software for asphaltene and wax precipitation modeling incorporating formation damage by asphaltene deposition in oil reservoirs Desarrollo de un software para el modelamiento de precipitación de asfaltenos y parafinas incorporando daño de formación por depositación de asfaltenos en yacimientos de petróleo

Abstract

This article describes different thermodynamic models to predict the precipitation of organic material (paraffin and asphaltenes) using state equations that predict the time at which precipitation starts. We describe a physico-mechanic model for asphaltene deposition that quantifies the amount of asphaltene deposited around a well at different time intervals. Was subsequently developed a program called SMAP that allows characterize and splitting the Cn t component, lumping the pseudo-components, model the asphaltene and paraffin precipitation, quantify, analyze and predict formation damage by asphaltene deposition in the reservoir By comparing the results with experimental data found in other articles, the CMG and some actual field data, it is possible to do the validation and accurate assessment of the project.
