Abstract
Una herramienta de perforacion para localizar una perforacion blanco que contiene un miembro conductor a partir de una segunda perforacion y dirigir la trayectoria de la segunda perforacion con relacion a la perforacion blanco incluye un excitador de corriente electrica que tienen un espacio aislado; un magnetometro de tres ejes colocado dentro de un bastidor no magnetico colocado dentro de un tubo no magnetico, el mantenimiento de tres ejes esta colocado debajo el excitador de corriente electrica; una broca de perforacion colocada debajo del magnetometro de tres ejes; un tubo hueco conectado entre el excitador de corriente electrica y el magnetometro de tres ejes; y una herramienta de medicion mientras se esta perforando. El excitador de corriente genera una corriente electrica a traves del espacio hacia la parte de la herramienta que esta debajo del espacio aislado. En un metodo, se genera una corriente a traves del espacio aislado hacia la porcion de la herramienta debajo del espacio aislado hacia el material conductor en la perforacion blanco retornando a una porcion del ensamble de fondo de pozo arriba del espacio aislado produciendo de esta manera un campo magnetico blanco. Efectuar una medicion del campo magnetico blanco en el ensamble de fondo de pozo y el campo magnetico terrestre; y determinar la posicion de la segunda perforacion con relacion a la perforacion blanco. Despues guiar el ensamble de fondo de pozo para perforar el segundo pozo a lo largo de una trayectoria con relacion a la perforacion blanco.
