Abstract

Los datos se comunican desde los sensores en una localizacion del fondo del pozo cerca de una broca de perforacion al equipamiento de superficie. La comunicacion con el equipamiento de superficie puede ser directa o puede pasar a traves de una serie de nodos. En algunos casos, los nodos se reconfiguran inteligentemente para obtener las velocidades de datos deseadas, alcanzar los objetivos de administracion de energia y/o compensar los nodos fallidos.
