Abstract

Un dispositivo de aislamiento para un tapón de fractura, el dispositivo de aislamiento que incluye un asiento de bola que tiene una superficie de asiento y una bola configurada para entrar en contacto con la superficie de asiento, en donde un perfil de la superficie de asiento corresponde a un perfil de la bola. Un tapón de fractura que incluye un mandril que tiene un extremo superior y un extremo inferior, un elemento de sellado dispuesto alrededor del mandril, y un asiento de bola dispuesto dentro de un agujero central del mandril, en donde el asiento de bola incluye una superficie de asiento que tiene un perfil no lineal. Un método para aislar zonas de una formación de producción, el método que incluye correr un tapón de fractura hacia el fondo del pozo hacia una localización determinada entre una primera zona y una segunda zona, disponer una bola dentro del tapón de fractura, y asentar una bola en un asiento de bola del tapón de fractura el asiento de bola que incluye una superficie de asiento que tiene un perfil que se corresponde sustancialmente con el perfil de la bola.
