Abstract

1.- Un método para uso en un pozo, que comprende:crear una condicion de sobre balance transitorio en un intervalo de pozo de modo que una presion del intervalo del pozo sea mayor que una presion de reservorio en una formacion adyacente, en donde crear la condicion de sobre balance transitorio hace que una region cercana al pozo de la formacion aumente en presion; y reducir la presion en el intervalo del pozo a una tasa que produzca una condicion de bajo balance relativo en el que la presion en el intervalo del pozo es menor que la presion de la region cercana al pozo de la formacion. 2.- El método de la reivindicacion 1, que ademas comprende disparar una pistola perforadora creando la condicion de sobre balance transitorio, en donde la reduccion de la presion ocurre después de disparar la pistola perforadora. 3.- El método de la reivindicacion 2, en donde la creacion de la condicion de sobre balance transitorio y la reduccion en la presion en el intervalo del pozo se hacen mediante el uso de un dispositivo que tenga un elemento inflable. 4.- El método de la reivindicacion 3, en donde la reduccion de presion en el intervalo del pozo se hace usando una camara de oleada (flujo instantaneo) de la pistola perforadora o deteniendo abruptamente la inflacion del elemento.
