Implementación del método isoconversional como herramienta diagnostico para un modelo cinético de reacción propuesto a un proceso de combustión in situ en un crudo Colombiano
A pesar de que la combustión in situ (CIS) es considerada como un método EOR con un gran potencial; es mucho más complejo que otros métodos térmicos debido a la difícil comprensión de la cinética de reacción, los múltiples mecanismos de desplazamiento y a la intensa dinámica de cambio de fase.

Modelo Cinético De Reacción
Principio Isoconversional.
Although in situ combustion (ISC) is considered as a great potential EOR method it is more complex than other thermal methods because of the difficult understanding of the reaction kinetics
the multiple displacement mechanisms and intensively changing phase dynamics. In fact
most failed ISC projects are attributed to the inaccuracy and / or lack of study of the kinetics due to its complexity and limited experimental capacity to identify dominant reaction mechanisms in the process. In order to evaluate field-scale ISC performance and make reliable predictions under different operating conditions is important to build a suitable reaction kinetic model that allow represent oil oxidative behavior. In this sense
it is necessary to have a data interpretation tool in order to establish the validity of the kinetic reaction model proposed. The isoconversional principle is considered as a promising method for identifying the complicated multi-component
multi-step reaction kinetics during the ISC process
being a model-free data interpretation method that naturally separates activation energy from the reaction model. The isoconversional technique characterizes the effective activation energy versus oil conversion on a graph called "isoconversional fingerprint" which is unique and unrepeatable for each type of crude
but all should exhibit a similar trend. From this
we pretend to establish the validity of a kinetic reaction model that should be able to reproduce by numerical reservoir simulation a similar trend to an isoconversional fingerprint obtained experimentally in case of not having the real as is the case of study.
