Description:	Reducción en la producción de aceite y gas condensan pozos debido a la implementación de parafina siendo un serio problema que enfrentan muchos de los operadores. Muchas investigaciones se han llevado a cabo, y muchos métodos se han desarrollado para limpiar el pozo, tuberías y equipo de superficie de la deposición de parafina, pero no existen muchos estudios sobre la disolución de depósotos de parafina con el fracturas y los espacios de poros en las reservas.
