Abstract

Un método para insertar una herramienta en un orificio de pozo incluye desenrollar una tubería enrollada en el orificio de pozo a una profundidad seleccionada en el mismo; cuando la tubería está a la profundidad seleccionada, la tubería se desacopla, una herramienta se inserta en el interior de la tubería; la tubería se reconecta y la herramienta se mueve a lo largo del interior de la tubería.
