A shortcut model to estimate oil production rate in VAPEX process

摘要

An analytical model for estimating the oil production rate in the vapor extraction process (VAPEX) is presented in this work. It regards the most effective properties of fluid and reservoir in the form of the Rayleigh number. The model involves three coefficients (x(1), x(2) and x(3)) that are determined through minimizing an objective function based on the difference between experimental VAPEX data and calculated data. The strength of the model was examined through comparison experimental work. Having an average relative error of 15% against the real data, the model showed its high capability for predicting the VAPEX production rate.
